Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The mobile distributor-chopper comprises a hopper (2) mounted on the chassis frame (1). At the bottom of the hopper (2) there are two horizontal counter-rotating longitudinal conveyor (3 and 4) arranged in one plane. Between their turns a cross conveyor unloader (12) is placed. Above the horizontal longitudinal conveyors (3, 4) the blade drum choppers (5 and 6) are mounted opposite one another. Above the blade drum chippers (5 and 6) the comb rakes (8 and 9) are mounted, consisting of a base with rakes (10 and 11) cantilevered attached to it. The bases of the combs (8 and 9) are fixed to the side walls of the hopper (2) and mounted with providing partial coverage by the rakes of the housing of the blade drum chopper (5 and 6). The rakes (10 and 11) are arranged between the blades (7). The ends of the rakes (10 and 11) of one row of the combs are close to the other row and are located beyond the rotation trajectory of the blades (7) of the roller choppers (5 and 6).

EFFECT: improved process of feeding chopped fodder to the conveyor unloader and in the manger is provided, design simplification, and reduction of dustiness of zone of fodder distribution.

Description

The invention relates to agriculture, in particular to mobile devices for distributing feed on cattle farms.

Known mobile feed dispenser containing mounted on the chassis of the hopper, on the bottom of the hopper are placed in the same plane two horizontal counter-rotating longitudinal conveyors mounted with the formation of the gap between their turns, a transverse discharge conveyor, placed at the horizontal junction and installed above them one against the other feed choppers (see Patent No. 2382550, class A01K 5/00, 2008).

In the given mobile dispenser, it is possible to load on horizontal longitudinal conveyors and distribute various types of feed, including formed in rolls. The design of the given dispenser is complicated by the presence of a number of chain transmissions, the metal consumption does not provide high-quality feed when using output at the output due to the low degree of grinding.

Closest to the proposed one is a mobile feed dispenser-grinder, containing a hopper mounted on the chassis frame, feed conveyors mounted in the hopper, an unloading conveyor, knife drum grinders mounted on the frame one against the other, and a “still chamber” adjacent to the choppers (see patent No. 2219765, CL A01K 5/00 2002).

In the process of using the above dispenser, the crushed feed during rotation of the chopper is discharged to the discharge conveyor through the recirculation channel and the “stilling chamber”, while in the recirculation channel the feed is exposed to the oncoming air flow generated by the excess pressure in the chamber, as a result small particles of feed and dust are carried out outside the distributor. The design of the “stilling chamber” is complicated by the presence of a floating conveyor mounted above the unloading one.

The proposed technical solution is aimed at improving the process of feeding chopped feed to the unloading conveyor and the feeder, simplifying the design of the “stilling chamber”, and reducing the dustiness of the feed distribution zone. This is achieved by the fact that in a mobile distributor-grinder of stalk feed containing a hopper mounted on the chassis frame, two horizontal counter-rotating longitudinal conveyors are mounted on the bottom of the hopper, mounted to form a gap between their turns, located at the junction of the longitudinal horizontal conveyors transverse unloading conveyor and knife drum grinders mounted above horizontal longitudinal conveyors against each other, while above the knife Combine tines are installed with drum grinders, consisting of a base with tine racks cantilevered to it, while the bases of the tines are fixed to the side walls of the hopper and mounted to provide a partial tine coverage of the knife drum grinder body, place tines between the knives and bring the ends of the tines together of one row of tines with other nearby, as well as ensuring the location of the ends of the rake outside the trajectory of rotation of the knives of drum grinders, the base of the combs fixed with the possibility of changing the degree of convergence of the ends of the rake.

According to the patent and scientific and technical literature, the claimed combination of essential features is unknown.

Figure 1 shows a mobile chopper-distributor of stalked feed, figure 2 is the same, plan view.

The mobile distributor-grinder of stalked feed contains a hopper 2 mounted on the chassis 1, longitudinal horizontal conveyors 3, 4, drum grinders 5, 6 with chopping elements-knives 7, made in the form of segments or rods, mounted on the side walls of the hopper 2 with the possibility of rotation and fixing their position of the base of the comb rake 8, 9.

The cantilever rake 10, 11 is mounted with a partial coverage of the surface of the drum of the grinders 5, 6 and ensuring their placement between the grinding elements-knives 7, while the ends of the rake of one row are close to the ends of the rake of the other row and collectively the rake 10, 11 form a cone-shaped “soothing” camera. " The transverse unloading conveyor 12, the reflector 13. The gaps between the rake at the inlet sections of the knife elements 7 are made in excess of the gaps in the areas of exit from them, as a result, the feed mass is removed from the knives 7.

The drive of the choppers from the PTO of the traction means, the drive of the feed and the transverse conveyor (as an option) from the hydraulic system of the traction means.

A mobile dispenser-grinder stalked feed works as follows.

The PKU-0.8 or PF-0.5 loader or other means load the feed onto conveyors 3, 4 located in the hopper, the feed distributor is located in the aft passage, includes a PTO, hydraulic conveyors 3, 4, 12.

Conveyors 3, 4 bring the feed to the grinders 5, 6, the feed is ground and knives 7 are introduced into the “still chamber” at extended intervals between the rakes, and then, crossing the narrowed intervals of the rake at the exit from the chamber, the rest of the feed is removed.

The knives of 7 drum shredders intersect the gaps between the rake racks above their ends, while compressing the feed accumulated in the “still chamber”, as a result, the feed pressure on the rake increases, under the influence of rake pressure, within elastic deformation, they move apart and the feed falls onto the transverse unloading conveyor 12 The feed accumulated in the “still chamber” partially serves as a filter of the air flow formed by the rotation of the drum grinders.

In the proposed mobile stalk feed chopper-distributor, the design of a “stilling chamber” is simplified, when loading the hopper with various types of feed, it is possible to obtain a feed mixture, feed losses are reduced, and dust content in the livestock building is reduced during loading of the unloading conveyor.
