Disc-type adjustable wheat plucker

Abstract

The invention discloses a disc-type adjustable wheat plucker, which comprises a main shaft 3 arranged on a bearing support 5. The main shaft 3 is provided with a ground gripping fluted disc 1, a coupling 16, a shaft sleeve 17 and a plucking disc 23. A first counter shaft 8 and a second counter shaft 22 are respectively connected with the main shaft 3 via a first toothed chain combination 29 and a second toothed chain combination 28. A driving gear 5 on the first counter shaft 8 is meshed with a driven gear 6 arranged on a third counter shaft 21, a fourth counter shaft 20 is connected with the third counter shaft 21 via a third toothed chain combination 7, and the second counter shaft 22 is provided with a ground breaking cutter and hammer unit 18. A transmission device 19 is arranged on the fourth counter shaft 20 and the third counter shaft 21 and is provided with a timing turntable 9 and a gate pole 10. A fifth counter shaft 24 is connected with the main shaft 3 respectively via a fourth toothed chain combination 4 and a fifth toothed chain combination 27 correspondingly arranged on the sleeve 17, and the fifth counter shaft 24 is provided with a locking disc 25 which is provided with a plucking fork 26. The disc-type adjustable wheat plucker has the advantages of simple structure, convenient use and effectively improved labor efficiency.

Description

technical field [0001] The invention relates to an agricultural tool, in particular to a disc-type adjustable wheat pulling machine. Background technique [0002] In the western rural areas, most of the dryland wheat is mainly harvested by uprooting, and after years of experience in agricultural activities and consultations from various sources, it has been confirmed that the harvesting method of uprooting wheat is compared with similar harvesting wheat. The starch content is higher, and the quality and taste of the ground flour far exceed the latter. There are flour mills in our county that specialize in purchasing this kind of wheat-processed and refined flour, and the selling price is more than double that of ordinary flour. However, in the vast western rural areas, for this harvesting method, there are few suitable agricultural machinery to match it. If manpower is used, the labor intensity is high and the labor efficiency is low. [0003] Chinese patent 94243741 propos...

Problems solved by technology

However, in the vast western rural areas, there are few suitable agricultural machinery for this harvesting method. If manpower is used, the labor intensity will be high and the labor efficiency will be low.

[0003] Chinese patent 94243741 proposes "a continuous wheat pulling mechanism", but it is difficult to get rid of the following disadvantages: 1. The volume and weight are huge, and the operation mode is too monotonous, so it is difficult to ensure that the wheat pulling structure is in good contact with the straw and works; 2. Pure 3. After pulling out the wheat, the wheat stalks cannot be arranged in an orderly manner, which brings trouble to people's work; 4. It is difficult to adapt to changing planting types (such as wheat species, rows, etc.) Spacing, degree of thickness, etc.), not suitable for large-scale promotion
