RU2220567C1 - Feeder-grinder for fiber feeds formed into rolls - Google Patents

Abstract

FIELD: agricultural engineering, in particular, feed grinding equipment. SUBSTANCE: feeder-grinder has grinding drums and longitudinal chain-and-plate conveyor, which are mounted inside hopper. Chain-and-plate conveyor is pivotally fixed at its one side and is spring- loaded at its other side and connected to roll retainer by means of lever. Rear part of hopper bottom is inclined toward transverse (discharge) conveyor. EFFECT: uniform distribution of feeds from rolls and reduced power consumption. 1 dwg

Description

 The invention relates to agriculture, to devices for grinding feed.

 Known feed dispenser-chopper, comprising a longitudinal conveyor located in the hopper, feeding bales of bales to rotating chopping beaters equipped with knives. An unloading conveyor [1] is located in front of the feed hopper-chopper hopper.

 The disadvantage of this feed chopper-grinder is the low uniformity of the particle size distribution of the crushed material, high energy consumption, due to the resistance to rotation of the second roll of the first.

 Increasing the uniformity of the distribution of feed formed in rolls and reducing energy intensity is achieved by the fact that the longitudinal chain-slat conveyor is pivotally fixed on one side and spring-loaded on the other and connected to the roll clamp by means of a lever, while the back of the hopper bottom is inclined to side of the transverse (discharge) conveyor.

 The drawing shows a distributor-grinder of coarse feed formed in rolls, General view.

 The distributor-grinder of coarse feed formed in rolls consists of a hopper 1, in front of which there are chopping drums 2 equipped with knife segments 3, and a transverse (unloading) conveyor 4. The longitudinal chain-slat conveyor 5 is pivotally fixed on one side, and on the other, it is spring-loaded with a spring 6 and connected to the retainer of the roll 7, which consists of a vertical and horizontal shelf by means of a lever 8. The drive of chopping drums 2, longitudinal chain-strap 5 and transverse (unloading) 4 transp rterov carried by the tractor PTO through the driveline. Under the grinding drums 2 there is an opposing deck 9 mounted pivotally. On the supply side of the chain-slat conveyor 5, between the grinding drums 2 and the roll, a restrictive grill 10 is installed, which is pivotally connected to the hopper 1. In the rear of the hopper 1 is a fixed frame 11 for the second roll, which is connected by a spring 12 to the retainer of the roll 7.

 The device operates as follows. From the tractor PTO through the gearbox the grinding drums 2, the longitudinal chain-slat 5 and the transverse (discharge) 4 conveyors come into motion. As a result of the interaction of the longitudinal chain-slat conveyor 5 with the roll, the latter begins to rotate around its axis, while the knife segments 3 of the grinding drums 2 remove the layer of feed material, grind it and give it to the transverse (unloading) conveyor 4, through which coarse feed is fed into animal feeders.

 When loading into the hopper 1 of the second roll, it is held with the latch 7, without contacting the previously loaded roll and without exerting lateral pressure on it.

 As the first roll decreases, the spring 6 of the longitudinal chain-slat conveyor 5 is unclenched, moving the lever 8 in the vertical direction until it interacts with the horizontal shelf of the roll retainer 7. The spring 12 is compressed, while the vertical shelf of the retainer of roll 7 occupies a horizontal position, which facilitates free rolling second roll to the feed longitudinal chain-slat conveyor 5. The second roll moves to the first, providing further uniform grinding of feed during loading Kera rolls.

 After the roll has rolled onto the longitudinal chain-slat conveyor 5, the spring 6 is compressed by gravity, releasing the horizontal shelf of the retainer of the roll 7, which under the action of the spring 12 brings the vertical shelf of the retainer to its original position.

 The technical novelty of this invention is the availability of a clamp for the second roll 7. This device consists of a fixed plate 11, fixed at a certain angle, in order to freely move along the inclined plane of the roll to the feeding longitudinal chain-slat conveyor 5. The roll clamp 7 is pivotally attached to the plate consisting of two shelves: vertical and horizontal.

 The horizontal shelf and the fixed plate 11 are connected by a spring 12. Due to the hinged connection, the vertical and horizontal shelf can freely move under the action of force. Under a certain pressure, the vertical shelf tilts, releasing the second roll. The horizontal shelf is as close as possible to the fixed plate 11, the spring 12 is in a compressed state. After the second roll interacts with the longitudinal chain-slat conveyor 5, the pressure on the horizontal shelf disappears, the spring 12 is opened, the vertical shelf of the retainer of the roll 7 is returned to its original position.
