Problems solved by technology

Due to the large structure and limited speed of the toothed belt pick-up device, it is difficult to realize wide-width and high-speed pick-up operations
The cam slide type elastic tooth roller pick-up device is not only complicated in structure, but the repeated impact of the roller on the cam plate in the slideway is likely to cause wear and tear of the parts and fatigue damage of the cam plate, and the periodic vibration of the pick-up device reduces the picking stability. Upward movement needs to overcome the friction of the guard plate, and the rebound of the spring teeth off the ground will "hit" the peanut plant. During t

Embodiment 1

[0060] Embodiment 1: as Figure 1-3 As shown, a step-by-step peanut pick-up device without guard plate fixed and movable teeth of the present invention includes fixed teeth 1, pick-up roller 3, seedling unloading plate 12, sieve plate 14 and auger 8, and the pick-up roller 3 The two ends of the roller shaft are fixed on the left and right side plates 6, 11 of the shell through the pick-up roller bearing seat 2, and a row of fixed fixed teeth 1 is arranged at the front and bottom of the pick-up roller 3, and the fixed teeth 1 have an arc The front end of the auger 8 is installed behind the pick-up roller 3 through the auger bearing seat, and a sieve plate 14 is arranged under the auger 8, and the sieve plate 14 is connected to the pick-up roller 3 for transition. Connected seedling unloading plate 12; when working, the fixed teeth 1 are drawn into the ground to scoop up the peanut plants and move upwards to a certain height along the arc-shaped working surface under the action ...

Embodiment 2

[0076] Embodiment 2: The difference between this example and Embodiment 1 is that 6 pick-up teeth are used in this example, and the adjacent pick-up teeth are sequentially staggered by a phase angle θ of 15°, forming a "V"-shaped wave arrangement along the axial direction. The reclining angle of the picking teeth on the picking piece 302 is α=25°, and the length of the picking teeth is L 1 =100mm, height h between the tooth end of the pick-up piece 302 and the ground 1 = 30mm.

[0077] The side shape of the fixed tooth 1 is an involute curve, and the radius of the base circle is R 1 260mm, α 0 = 60°, α n = 108°.

[0078] The angle β between the picking teeth and the involute tangent of the seedling unloading plate 12 in the counterclockwise direction is always greater than the clamping angle of the peanut plant, 82°≤β≥115°.

[0079] Described seedling unloading plate 12 and sieve plate 14 are curve plate, respectively by curve and constitute, of which is based on R ...

Embodiment 3

[0081] Embodiment 3: The difference between this example and Embodiment 1 is that seven pick-up teeth are used in this example, and the adjacent pick-up teeth are sequentially staggered by a phase angle θ of 13°, forming a "V"-shaped wave arrangement along the axial direction. The reclining angle of the picking teeth on the picking piece 302 is α=20°, and the length of the picking teeth is L 1 =60mm, height h between the tooth end of the pick-up piece 302 and the ground 1 = 15mm.

[0082] The side shape of the fixed tooth 1 is an involute curve, and the radius of the base circle is R 1 is 150mm, starting angle α 0 =72°, end angle α n = 120°.

[0083] The angle β between the picking tooth and the involute tangent of the seedling unloading plate 12 in the counterclockwise direction is always greater than the clamping angle of the peanut plant, 75°≤β≥80°.

[0084] Described seedling unloading plate 12 and sieve plate 14 are curve plate, respectively by curve and constitu...

Abstract

The invention discloses a fixed tooth and movable tooth combined step-by-step peanut picking device, and belongs to the technical field of peanut harvesting machinery. Comprising fixed teeth, a picking roller, a seedling unloading plate, a sieve plate, a shell and an auger, the two ends of a roller shaft of the picking roller are fixed to a left side plate and a right side plate of the shell through picking roller bearing seats, a row of fixed teeth are arranged below the working front end of the picking roller, each fixed tooth is provided with an arc-shaped working face, and the end, close to the picking roller, of each fixed tooth is tangent to the circumference of the picking roller; the auger is arranged behind the picking roller through an auger bearing seat, a sieve plate is arranged below the auger, and the sieve plate is connected with a seedling unloading plate which is in transition connection with the picking roller and is matched with the auger to form a kinematic pair. The peanut picking process is divided into two steps, the fixed teeth go deep into the earth surface by a certain depth to shovel up peanut plants, then the peanut plants are driven by the picking roller to move upwards, and the picking and pushing process is completed. Peanut plants are unloaded by the seedling unloading plate and then slide into a rear auger.

Description

technical field [0001] The invention belongs to the field of agricultural machinery technology and peanut harvesting machinery technology, and in particular relates to a fixed-moving teeth combined step-by-step peanut picking device. Background technique [0002] Peanut is an important oil crop and economic crop in the world and even in my country. It is also the most competitive agricultural product for export and earns foreign exchange in my country. It has a very high status in China. The perennial planting area of ​​peanuts in my country is 70 million mu, accounting for about 18% of the world's peanut planting area, second only to India and ranking second in the world; the output is 17 million tons, accounting for about 40% of the world's total peanut production, ranking first in the world . In my country's oil crops, the yield of peanuts ranks first, with an oil content as high as 50%. At the same time, peanut meal and straw are high-quality animal feed, which play an i...
