Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to loaders, grinding chitomel m feed.

The purpose of the invention is to improve the quality of grinding feed.

FIG. 1 shows a feed chopper, side view; in fig. 2 - the same, top view; FIG. 3 shows a separating device, side view; FIG. 4 - The same, top view.

The feed chopper loader consists of an intake organ 1 made of two cutters - drums mounted at the end of a rotary pneumatic pipeline 2 with a fan 3 installed in it and located in front of the fan 3 of the chopping drum 4 with working bodies 5 interacting with counter cutters 6. In the pipeline 2 under the chopping drum 4 a separating device 7 is placed, formed by a series of parallel shafts 8c with ribs 9 fixed to them. The ribs 9 are fixed on the shafts 8 in chess order so that The scraps of one shaft are located between the edges of the second shaft, and the working bodies 5 of the chopping drum are placed in the inter-ribs space.

The pneumatic pipeline 2 above the chopping drum 4 is made curved with the formation of the return channel 10. In addition, in the pipeline 2 (under the inlet end of the separating device 7) there is a hole with a formation between the separating device 7 and the walls of the pipeline 2 of the inlet channel 11, the flow section of which made increasing in the direction towards the exit end of the separating device 7.

To unload the finished product, a discharge deflector 12 is installed on the fan 3.

Loader chopper feed works as follows.

The feed particles separated from the monolith by the intake organ 1 are fed to the chopping drum 4 and the separating device 7, which, by rotating the shafts 8 with the ribs 9, agitates the feed, producing separation, while the chopping drum 4 chops the non-separated particles by interacting its working bodies 5 with counterbores 6,

Particles that are not ground in one revolution of the chopper, are returned through the return channel 10 to be re-crushed.

Separated particles, get into the air inlet 11, otsashayutsya fan 3 through line 2 and discharged through the deflector 12.

Depending on the type of material and the task, all shafts-B with ribs 9 of the separating device 7 rotate either in one direction or in pairs in different directions at different speeds. The edges of the ribs 9 can be made in the form of a blade, smooth or grooved.

Claims (2)

1. LOADER-GRINDER OF FEEDS, containing a suction body and a pneumatic pipe in which a fan and a rotating grinding drum with working bodies are installed, characterized in that, in order to improve the quality of grinding of feed, the grinding drum with working bodies is installed in front of the fan and is equipped with a bottom separating device, made in the form of a deck, consisting of a series of parallel shafts with staggered ribs on them, interlocked by ribs, in the intercostal spaces on which the working bodies of the grinding drum are located, and the pneumatic pipeline above the grinder is curved to form a return channel, and a hole is made in the pipe under the inlet end of the separating device with the formation of an air intake channel between the separating device and the walls of the pipe, the passage section of which is increasing towards the exit end of the separation device. 2. The loader-chopper according to claim 1, characterized in that the ribs are made in the form of flat geometric figures, in which the angles at the vertices are not more than 90. SU ,,, 1250204
