Description

Transgürters-spreads are known: fertilizers made in the form of a carriage that is attached to a tractor, whose bottom of the body is blocked by a working branch of the conveyor, feeding the mass of fertilizers in the body towards the crushing drum installed above the conveyor at the rear open end of the body. It is also known in such spreaders to use a pair of removable rotating horizontal discs for dispersing some types of fertilizer. However, these conveyor-spreaders have the disadvantage that the fertilizer feeds onto the discs are uneven and the amount of fertilizers spread is controlled within very narrow limits. As a result, such spreaders are suitable for spreading limestone fats, peat crumb and organic-mineral mixtures of fun.

The described conveyor spreader is designed to spread both organic and mineral health as well as their mixtures, which is ensured by the presence of a wide range of adjustments.

The conveyor spreader has the special character that, with a grinding and uniform spreading of various types of fertilizers, the chopping drum is enclosed in a removable casing equipped with rear and two lateral guide plates, which are installed with the required angle of inclination and thereby ensure uniform feeding of fertilizers to the disks. For the purpose of spreading various fertilizers in the quantities corresponding to agrotechnical norms, the drive of its working bodies is promoted from the tractor, and the transfer to the conveyor is performed through a gearbox with a large number of steps.

FIG. 1 shows a spreader conveyor on the side, in FIG. 2 in plan, in FIG. 3 shows the housing of the chopping drum in the rear; FIG. 4 is a side view of the same casing.

The fertilizer spreader is designed as a vehicle with a body that is attached to the tractor and whose bottom is blocked by a working branch of conveyor 2 assembled on three endless chains 3, enveloping the end stars 4 and 5. The vertical pressure wall 6 is rigidly connected to the upper working branch of the conveyor in the initial position by the end wall of the shank and moving together with the conveyor branch (in Fig. 1 it is shown by a dotted line in the initial position and when approaching the drum). By means of the pressure wall 6, the mass of fertilizer in the body is fed to the chopping drum 7 installed at the rear open end of the body 1 in the liner 30.

To disperse the appropriate fertilizer types, the spreader-conveyor is equipped with two rotating horizontal discs 8 located behind the body / and provided with radial ribs 25.

The conveyor 2, the grinding drum 7 and both discs 8 are driven from the tractor's power take-off shaft using the shaft 9 and the transmission system, and to ensure spreading of various fertilizers in accordance with the agrotechnical norms, the speed-controlled transmission to the conveyor 2 and a box of speeds of 10 with a boat. a number of steps.

To ensure rigidity and reduce weight, the working branch of conveyor 2 is assembled only on: half of its length, corresponding to the length of the body bottom /, and is made of wavy steel plates //. The non-working branch of the conveyor 2 does not have any filling between the lines.

An aggregate feed on both scattering discs 8 fertilizers crushed by a drum 7 through a forked bunker 12 is carried out with the help of a casing 13. The casing has a folding visor 14 at the inlet, which is illuminated by a chain 15 and mounted on the body frame / and the uprights 16.

On the horizontal axis 17, parallel to the shaft of the grinding drum 7 and located on the curvilinear wall of the casing 13, the hinged plate 18 is hinged, adjusted by the inclination angle in the vertical plane with the screw 19.

The opposite side walls of the casing 13 are provided with two plates 20 installed at the required angle of inclination to the vertical planes by turning around the horizontal axes 21 of the side walls of the casing 13. The bolts 22 passing through the openings 23 of the rear wall of the bunker 12 are fixed to fix the position of the plates 20 .

The adjustable flaps 18 and 20 allow to provide a uniform supply of fertilizer from the chopping drum 7 to both spreading discs 8 with a different number of revolutions depending on the seeding rate of the fertilizers.

The drum 7 consists of a series of disks fixed on the vals with intervals between them. The cylinder liner of the drum is formed by several rings inserted and fixed between the discs. On top of the cladding, along the drum-forming, ribs are rigidly attached to its disks, bearing teeth 24 of a coaxial or other shape. The drum with comb strips of the same type mixes the fertilizer intensively and crushes them well. For automatic reversal of the movement of the conveyor 2 after the body has been emptied in gear, a friction clutch 26 is applied, which is controlled by the action of the vertical pressure wall 6 on the system of levers 28 by means of a bar 29.

At the same time, the cam clutch 27 of the conveyor stroke is disconnected and the friction clutch 26 is switched on, making the conveyor 2 and the pressure wall 6 idle towards the front end wall of the body.

In order to use the conveyor spreader for stacking fertilizers in stacks, the casing 13 with a forked bunker 12 and the spreading discs 8 are made detachable.

In winter conditions, removable skis are provided for moving the spreader.

Subject invention

1. Transporter - fertilizer spreader, made in the form of a wagon attached to the tractor, the bottom of the body of which is blocked by a working conveyor with a pressure wall installed on it, using a chopping drum installed above the conveyor at the rear end of the body, and two removable horizontal 1 to scatter crushed fertilizers, such as, for the purpose of crushing and uniform spreading of various types of fertilizers, the crushing drum is enclosed in a removable casing, setting over a forked disk hopper, and provided with one rear and two side guide plates hinged on the wall of the casing and mounted under

the required angle of inclination depending on the type and amount of fertilizer spread.

2. The form of execution of the transnorter-spreader on n. 1, characterized in that, in order to spread fertilizers in the quantities corresponding to agrotechnical norms, its working bodies are driven from the tractor's power take-off shaft, and transferred to the conveyor through a speed box with a number of steps.

3. The form of execution of the conveyor-spreader but PP. 1 and 2, that is, so that in order to automatically reverse the movement of the conveyor after the body has been emptied, a reverse friction clutch is used, which is activated by returning the pressure wall of the conveyor through a system of levers.
