Description
SPECIFICATION
A silage feeder for feeding silageto cattle or sheep
This invention relates to a silage feeder for feeding silage to cattle or sheep.
Silage has taken over fro hay as the most important winterfeed for cattle or sheep. The silage used to be mainly eaten by the animals from the face of a clamp but it is more and more being fed to the animals by means of central feeding passages or circular, rectangular ortombstone barrierfeeders. The use ofthe central feeding passages and the feeders enablestheanimalsto begroupedtogetherandthe silage is easier to eat than from the face of a clamp.
A problem exists in thatthe silage must always be fresh. lfthesilage is not fresh, then secondary fermentation occurs and the animals will not eatthe silage. In orderto prevent the secondary fermentation ofthe silage, the central feeding passages and the feeders must be empty before they are refilled. This means thatthe passages and the feeders have to be constantly replenished and this is time consuming to do. Furthermore, it is not always convenient to have to replenish the passages orthefeeders at indeterminate times on a twenty four hour basis.
It is an aim ofthe present invention to provide a silagefeederwhich obviates or reduces the above mentioned problem.
Accordingly, this invention provides a silage feeder forfeeding silage to cattle or sheep, which silage feeder comprises a container for receiving the silage, a feed portion positioned art a bottom parts the container, and an opening between the container and the feed portion, the container having sides which are parallel or which slope outwardly from the top ofthe container towards the bottom of the container, and the silage feeder being such that in use silage loaded into the container is removed and eaten via the opening and the feed portion, whereby the silage is caused to circulate through the silage feeder and be eaten substantially in order of its introduction, so that cattle or sheep cannot ignore existing silage in the silage feeder in favour of freshly introduced silage and so thatthe silage in the silage feeder can be replenished at intervals which are convenient to the person doing the replenishing.
The parallel or outwardly sloping sides of the container are advantageous in that they allow the silage easilyto flow downwardly so that it can be pulled through the opening by the cattle orsheep and eaten. If the container were to be constructed to have sides which slope inwardly to form a funnel arrange ment,then the silagewouldverysoon block up and the cattle or sheep would not be able to pull the silage down and through the opening.
Usually, the silagefeederwill include support means for supporting the container off the ground.
Preferably, the container is a rectangular or circular container. The container may however be of other shapes if desired.
The container may be provided at its top with guard meansforguarding the silage into the container. The guard means may also serve as a lid forthe container.
The container may have a floor which slopes upwaardly towards the centre off the floor.
Usually, the feed portion will comprise one or more feed trays. Also usually, thesilagefeederwill have one or two feed trays.
In one embodiment ofthe silagefeeder, thefeed tray orthe feed trays are such that they extend outwardly with respect to the container.
In another embodiment of the invention, the feed tray or the feed trays are such that they extend inwardlywith respecttothecontainer.Asilagefeeder having one or more inwardly extending feed trays may be more stable in usethan a silagefeederhaving one or more outwardly extending feed trays.
The feed tray or the feed trays may slope down wardlytowards the centre of the container.
The opening should be sufficiently small that it prevents the animals reaching too far into the container. Especially with cattle, the animals may be required to turn their head to pull the silage through the opening from the inside ofthe container. The cattle may be cows, heifers, bulls and bullocks.
The support means may be legs.
The sides of the silage feeder may terminate substantially level with the feed tray orfeed trays so that the legs are exposed. It is however preferred that the sides ofthe silage feeder extend to floor level so that the legs are covered. This arrangement effectively encloses the space between the legs and stops the space becoming filled with spilled silage. With the arrangements in which the legs are covered,thesilage feeder and its immediate surroundings are easierto keep clean.
Preferably, the silage feeder is provided with pads for preventing the legs sinking into soft ground.
Advantageously, the silage feeder includes skids for enabling the silage feeder to be pulled over the ground. The silage feeder can thus be moved relatively easily from site to site. Furthermore, the skids may act as strengthening members for strengthening the silage feeder. The skids may be mounted on the support means.
Thesilagefeeder may be madefrom a variety of materials. Presently preferred materials for the con tainerandthefeedtraysaregalvanishedsheetsteel and plywood. The silage feeder may have a frame which is made of box iron or angle iron.
The silagefeeder may include adjuster means for adjusting the height ofthe opening. Thus the height of the opening can be varied to suit the size of the animals being fed and alsoto suit differenttypes and lengths ofsilage. The silage may be any desired type of silage such for example as clamp silage or big baled silage. Generally, the silage may be any bulkfeed.
Preferably, the adjuster means are adjustable panels.
Alternatively, if desired, the adjuster means may be a sliding bar. The bar may slide in a pair of grooved tracks. The bar may be located at any desired position by means of pins locating in holes.
The drawing(s) originally filed was (were) informal and the print here reproduced is taken from
a later filed formal copy.
The silage feeder may include towing means for enabling the silage feeder to be towed from site to site.
The silagefeeder can be made in a variety of sizes and itwill obviously be largerforcattle than for sheep.
By way of example only, it is mentioned that a suitable silage feeder for cattle may be 240 cm long, cm wide with legs that are 230 mm high, feed trays that are 230 mm wide, and an opening that is from 415 to 615 mm high. As has been stated, other sizes may of course be employed forthe silage feeder.

Referring to Figures 1 and 2, there is shown a silage feeder 2 forfeeding silage to cattle or sheep. The silagefeedercomprises a container4which is for containing silage and which has vertical sides 6,8, 10, 12. The sides 6,8 are 240 cm long and the sides 10,12 are 120cm long. The container is thus rectangularin shape as shown.
Afeed portion in the form of a feed tray 14 extends outwardly with respect to the side 6. Another feed portion in the form of a feed tray 16 extends outwardly with respect to he side 8. The feed trays 14,16 are provided with upstanding lips 18,20 respectively.
An opening 22 exists between the bottom ofthe side 6 and the feed tray 14. A similar opening 24 exists between the bottom ofthe side 8 and the feed tray 16.
The silage feeder 2 also comprises support means in the form offour legs 26. The legs 26 supportthe container4 offthe ground with the feed trays 14, 16 at a feeding height.
Adjuster means in the form of a sliding bar 28 is provided to control the precise height of the opening 22.
A similar bar (not shown) is provided to control the precise height of the opening 24. Thus the height of the openings 22,24 can be precisely controlled for different sizes of animal and different types and lengths of silage.
In use, the container4will be filled from the top with silage and the cattle or sheep will pull the silage through the openings 22,24. Silage on the feed trays 14,16 can normally first be eaten and when more silage is required, this can fall or be pulled by the animals through the openings 22,24. Since the animals are eating from the bottom ofthe silage, it will be apparent that the container4can always be replenished from the top at a convenienttime and there will be no danger of the animals eating the replenished silage before the silage already in the container 4. Thus, the silage in the container 4 cannot remain sufficiently long during normal use for secondaryfermentation to occur.Thus all the silage will be eaten and, if the silage feeder 2 is sufficiently large, then the hitherto required frequent filling operations can be considerably reduced. The silage feeder 2 could, for example, simply betopped up once per day.
Referring nowto Figures 3 and 4, similar parts as in
Figures 1 and 2 have been given the same reference numerals and their precise construction and operation will notagain be given. Itwill beseenthatthesilage feeder2 shown in Figures 3 and 4 only has one tray 14.
The silage feeder 2 of Figures 3 and 4 can thus be used instead of known tombstone barrier feeders, or it can be lined up in central feeding passages, or it can be employed as a gate in a cattle yard and fed from outside.
Referring nowto Figures 5 to 22, similar parts as in
Figures 1 and 2 have again been given the same reference numerals and their precise construction and operation will not again be given.
Referring firstlyto Figures 5to 7, there is shown a silagefeeder 2 which is somewhat like the silage feeder 2 shown in Figures 1 and 2. In Figures 5 to 7, the feed trays 14,16 slope as illustrated. Supporting frame bars 30 are employed to support the outer edges ofthe feed trays 14, 16. The floor 32 of the container4 is in two halves 34,36 which gently slope as shown in Figure to meet at a central apex 38. The sliding bar 28 is replaced on either side by a sliding panel 40 for appropriately adjusting the size of the openings 22,24.
In Figures 5to 7, thefeed trays 14,16 are not provided with upstanding lips 18,20 as shown in
Figure 1.The trays 14,16 in Figures 5to7 are formed from sheet metal which is rivetted orwelded to the underside of parts of a box iron frame and also to the frame bars 30. The sloping of the feed trays 14,16 makes it unnecessary to employ the upstanding lips 18,20.
The silage feeder 2 illustrated in Figures 5 to 7 is a double sided heavy duty model intended for cattle.
The legs 26 shown in Figures Sto 7 are shorterthan the legs 26 shown in Figures 1 and 2 so thatthe trays 14,16 are nearerthe ground in the silagefeeder2 shown in
Figures 5to 7. The sloping floor halves 34, 36 help to prevent silage collecting in the bottom of the container 4, since the cattle always reach upwardsforfresh silage.Atriangularframe is fitted to supportthefloor 340fthecontainer4which, in Figures 5to7 is preferably made of plywood instead of galvanised sheet steel.
The silage feeder 2 shown in Figures 5 to 7 is advantageously best sited in the centre of a cattle yard. Clamp silage is the preferred type of silage but generally, any bulkfeed can be used, including big baled silage. The legs 26 are provided with pads42 so thatthe silage feeder 2 will not sink into soft ground, especially when it is fully loaded.
Referring nowto Figures 8 to 10, the illustrated silage feeder 2 is somewhat like the silage feeder 2 shown in Figures 3 and 4. The silage feeder 2 shown in
Figures 8 to 10 is a single sided model that has been designed for cattle. It will be noticed that the silage feeder 2 has a feed tray 14, which slopes and which extends inwardly with respect to the illustrated main frame 44 of the silage feeder 2. By providing the feed tray inwardly ofthe main frame 44, the entire silage feeder2 is given good stability during use.
Itwill be seen from Figures8to 10thatawooden plank 46 has been fitted to the main frame 44 and it acts as a guide at the top ofthe container 4. Thus the plank 46 helps to guide the silage into the container 4.
The other side can also be fitted with a plank 48 as shown in dotted lines if desired. The planks 46, 48 can also serve the dual purpose of acting as lids to close the container 4.
The silagefeeder2 shown in Figures 8 to 10 is provided with hooks for facilitating transportation.
It should be noted that the sides of the container 4 are not parallel but they widen out towards the base.
Such outwardly sloping sides facilitate the downward passage ofthe silage through the container4.
If desired, two or more of the silage feeders 2 may be bolted together in line.
The legs may be made to be adjustable for raising and lowering the height of the silage feeder 2. The legs are fitted with the pads 42 to prevent sinking in soft ground.
The silage feeder 2 shown in Figures 8to 10 can advantageously be placed against a wall, used as a gate to a cattle yard, or it may even be used as a wall itself.
Referring nowto Figures 11 to 13, the illustrated silagefeeder 2 is a double sided model constructed for sheep. The silage feeder 2 may be such that the container 4 holds approximately 350 kilos of silage.
Thesilagefeeder2 has a box iron frame part 50 and the silage is shown as silage 52 in Figure 13. The feed trays 14, 16slope as illustrated in Figure 11. Afeed guide/lid 46 is employed as shown in Figure 11.
The silage feeder 2 is provided with a towing link 54 for facilitating towing the silage feeder 2 from site to site.
If desired, the silage feeder 2 may be provided with wheels and a draw bar. Atray may also be provided to hold blocks or licksforthe animals.
The silage feeder 2 shown in Figures 1 1 to 13 may be further modified by the introduction of a movable feed bar (not shown).
Referring now to Figures 14to 16, there is shown a silage feeder 2 which is a simply constructed model designed to enable easy loading of feed when the silage feeder 2 is employed in central feeding passages. It will be seen that Figure 15 is in two parts in which Figure 15(a) is a view of the silage feeder 2 from the cattle side; and Figure 15(b) is a view ofthe silage feeder 2 from the central feeding passage side. The silage is fed in through the opening 56 shown in
Figures 14 and 16. Barriers 58 may optionally be employed as shown in dotted lines in Figure 14.
Referring now to Figures 17to 19, the illustrated silage feeder 2 has been specifically constructed to give ease of transportation. It will be seen that the silagefeeder2 is of simple construction and that the container 4 has no floor. Also, the silage feeder 2 has no legs. Without the floor and the legs, the silage feeder 2 is relatively light. It will be seen from Figure 19 thatthe walls 60,62 ofthe container 4 slope slightly outwardly as shown in order to enable a good flow of thesilagethroughthecontainer4.
Asshownin Figurel7,thecontainer4ishexagonal- ly shaped and it is formed in two halves 64,66. These two halves are provided with flanges 68 which enable the two halves 64,66 easily to be bolted together.
Thus, the container 4 and its attached parts can easily be dismantled for facilitating transportation and storage. In the dismantled condition, the dismantled halves 64,66 can fit into each other, thereby reducing the amount of space occupied.
Referring now to Figures 20 to 22, there is shown a silagefeeder2which is circular, sothat it has a cylindrical container4surrounded by a circularfeed tray 14. The cylindrical form ofthe container4 is shown most clearly in Figure 20. The container4 has an opening 22 at its bottom portion 70 through which the silage can be drawn by the animals using the silage feader 2. The silage feeder 2 shown in Figures 20 to 22 is especially suitable for big bales of silage.
Itwill be seen most clearly from Figures 20 and 22 thatthe container4is in two halves 72,74 which are joined together and held in the joined position by bolts 76. Frame parts 78 are provided and these frame parts 78 extend down into the circular feeding tray 14.
Itwill be appreciated that in the dismantled condition, the halves 72,74 can fit into each other so that they provide for each of transportation. The upwardly sloping members 80 give good interlocking when the two halves 64,66 are split and nestled into one another.
It is to be appreciatedthatthe embodiments ofthe invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected.
Thus,for example, the various illustrated silage feeders 2 can be made in any desired shape appropriate to the size of the sheep or cattle to be fed. In Figures 1 to 4, the sides 6,8,10,12 can be extended downwardly to coverthe legs 21. This stops the cattle orsheepkicking spiltsilageinthearea underneath the container4which is defined by the legs 26. Cleaning of the silage feeder 2 and its surrounding area is then made easier.
If desired, the legs 21 can rest on skids for enabling the silage feeder 2 to slide easily over the ground as it is pulled, for example by a tractor. Thus, with skids,the silage feeder 2 can easily be moved to various desired sites. If desired, the feed trays 14, 16 illustrated in
Figures 1 to 4 can be deeperthan shown. Although the sloping feed trays 14, 16 illustrated have not been provided with upstanding lips 16,18, upstanding lips may be employed as desired.
The illustrated silage feeders either have vertical sides or sides which slope outwardly from the top of the containers 4 to the bottom of the containers 4. This enables the silageto fall naturally towards the bottom ofthe containers 4 and the silage does not pack together and block, as will be the case if the sides of the containers 4 slope inwardly. Once the silage has been pulled through the openings 22,24, most of the silage not eaten as it is pulled through the openings 22,24 will drop into the feed trays 14, 16. The feed trays enable silage to be eaten off the feed trays withoutanyappreciabletendancyforthesilageto remain uneaten on the feed trays. Various types of desired silage may be employed so that the silage may be in theform of hay, straw or big bale silage.
