Description

The invention relates to machines for harvesting beet plantations using an inclined conveyor for wiping the seeds, composed of grooved slats.

The non-simultaneous ripening of beet juts, both in individual bushes and glomeruli on the stalks of the bush, is the main obstacle to the successful resolution of issues related to the mechanization of harvesting the specified crop. By virtue of this, the harvesting of beet landings is done manually, using the selective method of harvesting in most cases, i.e. cutting of upsetting bushes as they mature,

In the proposed machine, with mechanical continuous harvesting of beet plantations and with the purpose of wiping only mature beet seeds and leaving unripe, green straws for ripening, there is a reciprocating plate provided with rifles like beats on bilings above the carrier branch of the conveyor belt. threshing drums.

The drawing shows a rear view of the machine for cleaning beet landings.

The horizontal belt of the conveyor 2 of the machine on the non-field side is slightly raised and thanks to

(105)

bar 5 moves at an angle to the horizon. The cut-off landings fall on a horizontal canvas 2, which carries them to a plano-continuous conveyor 4, consisting of two endless chains, between which are grooved slats of the type of drum scourges or corners. For a more uniform entry of the stems to the conveyor 4 — the beater 5 is set at the point where the stems descend from the web 2. A threshing plate 6 is installed above the conveyor 4, having return-forward motion and provided with grooves like the threshing drums. The distance between the conveyor 4 and the plate 6 is adjusted by the suspension springs 30, 31.

The beetroot stems are brought up by the conveyor 4 and are simultaneously clamped in the swinging plate 6, and due to the movement of two hard surfaces — at different speeds and in different directions — the conveyor 4 and plate b, as well as the short distance between these surfaces, mature beetroot the seeds on the seedlings of the seeds are wiped and the green seeds left on the stems are dumped from the conveyor 4 onto the cattle board 7. At the point of decline, the partially threshed forward stems from the conveyor 4 to the cattle board 7,

chop bitter 8 is installed. The whole pile and planting stems with green seeds, on a pitched board / are dumped into a straw walker with 9, where the threshed beet seeds are separated from straw.

Straw strawers can be keyboard JO or solid-cascade, through the holes of which beet seeds and coarse heap fall to the below set sieve / 2. An air stream is directed under the sieve 12 of the 5/5 shaft, contributing to the best separation from the pile of seeds, which, falling through the sieve 12, fall into the screw 14, transporting the seeds to the pocket or slat conveyor / 5, and the last to the bunker 16. Left on the keys of the straw walker, the planting stems with a part of green seeds, as well as the heap left from the chaff (without grain) on a sieve 12, slide from the latter onto an ordinary canvas staple, from which they can be dropped to the ground as needed. In order to protect the wounded disembarking stems from cutting and the loss of such, the shearing apparatus of the landing gear against each disembarkation inter-row distance must be equipped with lifters 17, which have the task of raising the diseased stems of the landings.

If a large density of standing planting bushes is observed during harvesting, why on the field side of the runway sheaves losing seeds can be observed due to rupture of intertwined cropped stems of landings from uncut, then in such cases a well-known vertical cutting blade wheel is installed on the field board.

All the working bodies of the sheaves of the track, adapted for harvesting the landings, are driven by the cardan shaft 18 of the tractor. The front part of the cardan shaft / drives the connecting rod of the cutting device 19, and the back part of it with the chain gear 20 via the chain 21 drives the bitters 5 and (9. The conveyor 4 is driven by the cylindrical gear 22 mounted on the bitter shaft 8 and coupled to the gear 23, mounted on the conveyor drive shaft. The straw straw, auger and fan are driven in

movement chain drive from the shaft of the bitter 8. The conveyor 15 operates from the shaft of the screw 14.

The shaft of the bitter 5 drives the canvas conveyor 2 through the cylindrical teeth 24 and 25. The teeth 25 25 simultaneously sitting on the drive shaft of the conveyor are driven by means of a crank to the reciprocating movement the threshing plate 6, the oscillation size of which can change by shifting the fingers 26 in the holes of the teeth 25. The reel 27 rotates from the front end of the shaft, leading the web conveyor 2.

A skate board 2 is installed under the conveyor and, if seeds get onto it, such rolls down into the groove 29, from where the strips of the conveyor 4 can be picked up and carried out on the rolling doyou 7. Adapted in the manner described by the sheaves of the landing ramp, depending on - the width of the landing aisles, will be able to immediately remove three or four of the landing rows.

Piles of upstream stems discharged from the hopper should be laid in equal rows in the transverse direction of the machine, which will allow, after harvesting the landings, to fertilize and plow. Planting heaps will always / be in loose condition, since the landing stalks are very rough and packed in a mess, why the green beet seeds remaining on the stems will be able to reach and ripen freely, and the heaps, subjected to aeration, will dry out quickly. After drying, the heaps can be brought to the threshing ration, for the purpose of the final threshing of the seeds remaining on the stalks or the machine described, it is free to pass near the heap and stationary thresh the seeds following the example of the stationary threshing of grain harvesters from cops.
