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] Example 1: as Figure 1-Figure 4 As shown in the figure, a shovel tooth-tooth roller combined peanut pickup device of the present invention includes a pick-up shovel tooth 1, a drum guard 4, a pickup drum and a side plate. Side plates are arranged on both sides of the pickup drum, and the center axis of the pickup drum 5. The left and right side plates 9 and 10 passing through the two sides are respectively installed on the left and right bearing seats 8 and 11. The rollers of the pick-up drum are evenly spaced on the central shaft 5. The roller guard 4, at the front end of the pick-up device, each of the roller guards 4 is installed with the same arc-shaped pick-up shovel teeth 1 at the same position to form a row of pick-up shovel teeth; when working, the arc-shaped pick-up shovel The tooth 1 moves forward, the front end of the shovel tooth 1 goes deep into the ground, shovels up the peanut plants, and realizes the pick-up action; the pick-up drum rotates with the cen...

Embodiment 2

[0069] Example 2: The difference between this example and Example 1 is that the angle θ between the tangent point of the installation of the pick-up shovel teeth and the line connecting the center of rotation of the center axis of the pick-up drum and the Y-axis of the center axis is 0°, and the pick-up The base circle radius 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 gear teeth 2 and the peanut plant is a straight line segment, and the mounting angle θ of the gear teeth 2 3 is 20°. In this example, the gap between the adjacent guard plates is 21mm, which is larger than the thickness of the paddle, so as to ensure that the pick-up paddle teeth extend and retract between the guards.

[0072] The lifting station: The base circl...

Embodiment 3

[0073] Example 3: The difference between this example and Example 1 is that the angle θ between the tangent point of the pick-up shovel tooth installation and the line connecting the center of rotation of the pick-up drum central axis and the central axis Y-axis is 45°, and the pick-up The radius of the base circle of the involute curve of the shovel tooth is 52mm, corresponding to the central angle α 2 =116°,α 0 =45°,α n =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 gear tooth 2 and the peanut plant is a straight line segment, and the gear tooth installation angle θ 3 is 15°. The gap left between the adjacent guard plates is 23mm, which is greater than the thickness of the paddle wheel.

[0076] The lifting station: The base circle is centered at O 1 (9, -36), base circle radius R 1 is 36mm. The maximum length L of the gear teeth pr...

Abstract

A shovel tooth-tooth roller combined peanut picking device belongs to the technical field of agricultural machinery. It includes pick-up shovel teeth, roller guards, pick-up rollers and side plates. Side plates are arranged on both sides of the pick-up drum. The wheels are evenly spaced on the central axis, and there are roller guards between adjacent pulleys. At the front end of the pick-up device, arc-shaped pick-up shovel teeth with the same structure are installed at the same position on each of the roller guards to form a Rows of pick-up shovel teeth; when working, the arc-shaped pick-up shovel teeth move forward, and the working front end of the shovel teeth goes deep into the ground to shovel up the peanut plants to realize the picking action; the pick-up roller rotates with the central axis to realize the pick-up wheel lifting The actions of lifting, pushing and emptying back to the station. In the present invention, the peanut plants are scooped up by the shovel teeth; the follow-up lifting, pushing and other picking actions are completed by the pulley roller. It has the characteristics of small size, high pick-up rate and low loss rate.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a shovel-tooth-roller combined peanut picking-up device. Background technique [0002] Peanut is an important oil crop and cash crop in the world and even China. As the world's largest peanut production country, China ranked second in 2018 with a peanut planting area of ​​69.12 million mu, accounting for about 18% of the world's peanut planting area. The peanut pod output was 17,000kt, accounting for 40.70% of the world's total and ranked first. , The export volume of peanuts and products is 685kt, accounting for 20.22% of the world and ranking third. In domestic oil crop production, 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's soybeans mainly rely on imports, pea...
