Description

The proposed utility model relates to agricultural engineering and can be used in the transportation and grinding of rolls of hay or straw for bedding, distributing material to animal feeders.

Known conveyor distributor of coarse and succulent feed containing a body placed on the frame with a feed chain-slat conveyor, dispensing beaters and a transverse unloading conveyor located in the front of the body, a drive mechanism of the working bodies, a two-axis pneumatic wheel drive and a tow hitch / 1 /.

A disadvantage of the known device is its narrow purpose, due to the transportation and distribution to the feeders or to litter the animals already chopped material. The lack of a chopping apparatus creates the need for additional equipment for chopping hay and straw harvested in bulky bales and bales. Therefore, in this case, the unit costs of the work on the use of roll feed for farm animals increase significantly.

The closest in technical solution and the achieved result to the proposed utility model includes a feed distributor of roughage and bedding containing a body placed on a frame with a feed chain-slat conveyor, dispensing beaters and a transverse unloading conveyor located in the rear of the body, a drive mechanism for working bodies , pneumatic wheel drive, tow hitch and additional bearings / 2 / - prototype.

This device, designed for transportation and distribution of roughage, is similar in design to an analogue, and therefore the ongoing technological processes in it are similar to processes occurring in an analogue. Therefore, this machine has the same disadvantages as the analogue.

The essence of the proposed utility model consists in the fact that the well-known conveyor-distributor of roughage and bedding containing a body mounted on a frame with a feed chain-belt conveyor, a drive mechanism for working bodies, a pneumatic wheel drive and a tow hitch, the body in the rear part is equipped with a chopping drum knife type with a restrictive grating and a reflective plane placed above it, as well as an anti-counter deck wider than the chopping drum, connected to the rod g hydraulic cylinder mounted on the frame.

As a result of the analysis of literary sources, no identical execution of the proposed device was found. Moreover, distinctive features from the prototype signs give the claimed combination of new properties, manifested in a positive effect.

The installation of a chopping drum with a counter deck in the rear part of the body allows for the transportation, grinding and distribution of rolls of hay or straw in one technological process, which leads to a reduction in the unit cost of the work performed on the use of rolled feed for farm animals.

The presence of a restrictive grill eliminates excessive roll pressure on the knives of the chopping drum, making it difficult to start the machine and increasing the energy consumption of the process of grinding the roll.

Placing a reflective plane above the chopping drum of a knife-type drum contributes to the creation of a directing air stream generated by the rotating drum to feed the chopped feed outward either to the animal or

to the surface of the site as a litter. In addition, the reflective plane serves as a safety device, eliminating the accidental ingress of foreign objects or people into the danger zone during operation.

The installation of an anti-skid deck pivotally under the chopping drum allows the choice of its appropriate position to regulate the degree of chopping of the rolled feed required for the intended purpose (for feed or bedding by animals), or free access to the drum in case of unexpected clogging, breakdown and repair.

The presence of a hydraulic cylinder mounted on the frame and connected by a rod with a counter deck provides for the operational rotation of the deck from the tractor cab to change the degree of chopping of a roll of hay or straw, or to clean the chopping drum in case of unexpected clogging with straw, knitting twine and other foreign objects.

As a result, when the proposed device is operating, a positive effect is achieved that exceeds the effect of the prototype. A new set of features of the claimed device, providing a positive effect, has significant differences.

The figure shows a diagram of the conveyor-distributor of roughage and bedding.

The conveyor-distributor of roughage and bedding, aggregated by a 14 kN class 1 tractor, contains a frame 2 on which a body 3 with a feed chain-slat conveyor 4 is placed. At the rear of the body 3 there is a chopping drum 5 of knife type with a restrictive grill 6 and placed above it with a reflective plane 7. Under the grinding drum 5, the counter deck 8 is pivotally mounted connected to the rod 9 of the hydraulic cylinder 10 mounted on the frame 2. The frame 2 has a towing device 11 and is supported by a wheel drive 12. N frame 2 also has a mechanism mounted

drive working bodies 13, the torque to which is transmitted from the power take-off shaft 14 of the tractor 1.

The conveyor distributor of roughage and bedding works as follows.

Rolls (no more than two) from a stack of straw or hay are loaded into the body of a conveyor-distributor 3 by PKU-0.8A or PF-0.5 agricultural forklifts equipped with a PT-F-500 device for loading rolls. After loading the rolls and arriving at the walking platform, farm animals from the tractor cabin 1 include a power take-off shaft 14, which transmits torque through the drive mechanism 13 to the working bodies. In this case, the chain-slat conveyor 4, due to the translational motion, feeds the straw roll to the restrictive grid 6. In this case, the conveyor 4, interacting with the roll, makes it rotate around the axis. The knives of the rotating drum 5 are embedded in the layer of the counter-rotating roll, remove the feed layer and are fed to the opposing deck 8. The feed layer, passing between the knives of the drum 5 and deck 8, is crushed and thrown out under the influence of centrifugal force and air flow directed from the reflective plane 7 either in animal feeders or on the surface of the site as a litter. As the first roll decreases as a result of its grinding by a chain-slat conveyor 4, a second roll of hay or straw moves in the direction of the grinding drum 5. After grinding the first roll, the second one interacts with the knives of the drum 5, and the process is repeated.

To facilitate the launch of the conveyor-distributor of roughage and litter into operation, namely, to release the cutting knives of the drum 5 from the pressure of the roll or in case of an unexpected clogging of the deck 8 with the drum, the chain-slat conveyor 4 has a reverse stroke. Adjusting the degree of grinding of the feed or cleaning the drum 5 in case of unforeseen clogging is carried out by turning the deck 8 s

using a hydraulic cylinder 10, controlled from the tractor cab 1. Adjustment of doses of straw cutting on the surface of the site as a litter is carried out by the speed of the unit.

During experimental tests of an experimental sample of a feed distributor and distributor of roughage and bedding, winter rye straw was used in rolls weighing 200 ... 240 kg, density 100 ... 120 kg / m ³ and humidity 18 ... 25%. It has been established that the unit capacity is 1.8 ... 2.5 t / h with a power consumption of 25 kW, the unevenness of the finished product output does not exceed 15% with an average particle size of 30 ... 80 mm. The width of the straw cutting distribution for bedding to animals is 2.3 m. The overall dimensions of the machine are 6100 × 2250 × 2300 mm, weight - 2050 kg. The proposed conveyor distributor of roughage with the simplicity of design and reliability of the working bodies can be used to service 50 ... 400 heads of cattle.

The advantage of the proposed utility model in comparison with the prototype is to increase productivity and reduce the unit cost of the work performed on the use of roll feed for farm animals.
