Problems solved by technology

For the slide-type spring tooth roller pick-up device, the roller repeatedly impacts the cam disc in the cam slideway, causing the cam disc to be fatigued and damaged, and the pick-up device vibrates periodically, reducing the applicability and stability of the pick-up device
However, there is no slideway-type spring-tooth roller picking device, the spring teeth and the roller have no relative swing, relying on the curvature change of the upper guard plate to solve the pinching effect of the spring teeth on the peanut plants, but increasing the picking height, so that the peanut plants form a "pile" "
The arm-tooth combined pick-up device uses the arm-tooth roller and the spring-tooth roller pick-up device to work together, which can effectively prevent the peanut plants from "piling up", but forms a second blow to the peanut plants, increasing the peanut fruit drop rate and loss rate

Embodiment 1

[0053] Embodiment 1: as Figure 1-Figure 4 As shown, a shovel tooth-tooth roller combined peanut picking device of the present invention includes a pick-up shovel tooth 1, a drum guard plate 4, a pick-up drum and side plates, side plates are arranged on both sides of the pick-up drum, and the central axis of the pick-up drum 5 The left and right side plates 9 and 10 passing through both sides are installed on the left and right bearing housings 8 and 11 respectively, and the pulleys of the pick-up drum are evenly spaced on the central shaft 5, and the adjacent pulleys are provided with The drum guard plate 4 is at the front end of the pick-up device, and the same position on each drum guard plate 4 is equipped with arc-shaped pick-up shovel teeth 1 with the same structure, forming a row of pick-up shovel teeth; when working, the arc-shaped pick-up shovel The tooth 1 moves forward, and the working front end of the shovel tooth 1 goes deep into the ground to scoop up the peanut ...

Embodiment 2

[0069] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the included angle θ between the tangent point of the installation of the pick-up shovel described in this example and the center of rotation of the central axis of the pick-up drum and the Y-axis of the central axis is 0°, and the pick-up The radius of the base circle of the involute curve of the shovel tooth is 60mm, and the corresponding central angle α2 is 62°, α 0 =90°, α n =152°.

[0070] The lifting initial angle θ of the lifting station 1 is 42°, and the three phase angles are β1=118°, β2=72°, and β3=170° clockwise.

[0071] The contact side of the Pulun tooth 2 and the peanut plant is a straight line section, and the installation angle of the Pulun tooth 2 is θ 3 is 20°. In this example, there is a gap of 21 mm left between adjacent guard plates, which is greater than the thickness of the wheel, so that the teeth of the pick-up wheel are stretched out and retracted between the gua...

Embodiment 3

[0073] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the included angle θ between the tangent point of the installation of the pick-up shovel described in this example and the center of rotation of the central axis of the pick-up drum and the Y-axis of the central axis is 45°. The radius of the base circle of the involute curve of the shovel tooth is 52mm, corresponding to the central angle α2=116°, α0=45°, αn=161°.

[0074] The lifting initial angle θ of the lifting station 1 is 10°, and the three phase angles are β1=153°, β2=70°, and β3=137° clockwise.

[0075] The contact side of the Pulun tooth 2 and the peanut plant is a straight line section, and the Pulun tooth installation angle θ 3 is 15°. The gap left between adjacent guard plates is 23mm, which is greater than the thickness of the impeller.

[0076] The lifting station: The center of the base circle is O 1 (9, -36), base circle radius R 1 is 36mm. The maximum length L of the P...

Abstract

The invention discloses a shovel tooth and tooth roller combined type peanut pickup device, and belongs to the technical field of agricultural machinery. The shovel tooth and tooth roller combined type peanut pickup device comprises picking shovel teeth, roller protection plates, a picking roller and side plates; the side plates are arranged at the two sides of the picking roller, a center shaft of the picking roller penetrates through the side plates at the two sides to be installed on bearing pedestals, cattail wheels of the picking roller are evenly arranged on the center shaft at intervals, and the roller protection plates are arranged between the adjacent cattail wheels; at the advancing front end of the pickup device, arc-shaped picking shovel teeth of the same structure are installed at the same position of each roller protection plate, and a row of picking shovel teeth are formed; during working, the arc-shaped picking shovel teeth move forwards, the working front ends of the shovel teeth go deep into the ground surface to shovel up peanut plants, and a picking action is achieved; and the cattail wheels of the picking roller rotate along with the center shaft, so that actions of lifting, pushing and returning to a station of the cattail wheels are realized. According to the shovel tooth and tooth roller combined type peanut pickup device, the peanut plants are shoveledby the shovel teeth; and the subsequent picking actions such as lifting and pushing are completed by the roller with the cattail wheels. The pickup device has the characteristics of small size, high pickup rate, low loss rate and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a shovel tooth-tooth rolling combined peanut picking device. Background technique [0002] Peanut is an important oil crop and economic crop both in the world and in China. As the world's largest peanut production country, China ranked second with a peanut planting area of ​​69.12 million mu in 2018, accounting for about 18% of the world's peanut planting area, and ranked first with a peanut pod output of 17,000kt, accounting for 40.70% of the world's total. , The export volume of peanuts and its products was 685kt, accounting for 20.22% of the world and ranking third. In the production of domestic oil crops, peanut not only ranks first in output, but also has high oil content (about 50%) and good quality. It is one of the important edible oils in my country, and peanut meal is a high-quality feed resource. Especially in the situation that my country mainly relie...
