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

[0040] Example 1: as figure 1 As shown in the figure, a shovel tooth-spring tooth roller combined peanut picking device of the present invention includes a picking shovel tooth 1, a roller guard 6, a picking roller, a roller slideway 2 and a side plate, and the central axis 7 of the picking roller passes through the two The left and right side plates 10 and 14 of the side are respectively installed on the left and right bearing seats 9 and 15. The picking up spring teeth 5 are evenly arranged on the spring tooth shaft 12 of the picking drum, and a roller is provided between the adjacent picking up spring teeth 5. The guard plate 6, at the front end of the travel, each of the roller guard plates 6 is installed with the same arc-shaped pick-up shovel teeth 1 at the same position to form a row of shovel teeth; during operation, the arc-shaped pick-up shovel teeth 1 are accompanied by the working group. Move forward, shovel the peanut plants on the surface from the ground, make th...

Embodiment 2

[0056] like figure 1 , Figure 4-Figure 7 , Figure 9 , Figure 10 As shown in the figure, when the angle θ between the connecting line between the tangent point (elastic hinge point) of the pick-up shovel tooth 1 and the installation of the guard plate and the center of rotation of the central axis and the ordinate of the central axis is 30°, the radius of the base circle of the shovel tooth is R2 is 75mm, the corresponding center angle α2 is the fourth quadrant as the starting end, and the center angle relative to the starting point is the 97° segment involute, α 0 =60,α n =157°;α 0 is the starting angle of the involute of the shovel tooth, α n is the cut-off angle of the involute of the shovel teeth.

[0057] The phase angles corresponding to the three stations of lifting, pushing and idling are respectively β 1 ~β 3 , where the initial lift angle θ of the lift station 1 is 10 to 60°, the initial lift inclination angle θ 1 In order to pick up the angle between the...

Embodiment 3

[0066] Example 3: The difference between this example and Example 1 is that in this example, the angle θ between the connecting line of the center of rotation of the tangent point between the installation tangent point of the pick-up shovel tooth 1 and the guard plate 6 and the central axis and the ordinate of the central axis is 45 When it is °, the radius R2 of the base circle of the shovel tooth is 42mm, and the corresponding central angle α2 takes the fourth quadrant as the starting end, and the center angle relative to the starting point is a 116° segment involute, α 0 =45,α n =161°;α 0 is the starting angle of the involute of the shovel tooth, α n is the cut-off angle of the involute of the shovel teeth.

[0067] The lifting inclination θ in this example 1 is 13°, and the three phase angles are β1=146°, β2=99°, and β3=115° in the clockwise order.

[0068] like Figure 10 As shown, in this example: in the same section, O is the center of the central axis, and its coo...

Abstract

The utility model relates to a shovel tooth-elastic tooth roller combined peanut picking device, which belongs to the technical field of agricultural machinery. Including pick-up shovel teeth, roller guards, pick-up rollers, roller slides and side plates, the central axis of the pick-up roller passes through the side plates on both sides and is installed on the bearing seat respectively, and the pick-up spring teeth are evenly spaced on the spring tooth shaft of the pick-up roller On the top, there is a roller guard plate between the adjacent pick-up teeth. 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 roller guard plate to form a row of shovel teeth; the roller slideway is fixed. Installed in a side plate and slidingly connected with the spring tooth shaft on the pick-up drum, the invention scoops up the peanut plants by the shovel teeth; the pick-up drum rotates along the roller slideway, and due to the limitation of the roller slideway, the spring teeth wind around with the roller The central shaft rotates and oscillates periodically to realize the actions of lifting, pushing and emptying back to the station. And it can effectively reduce the impact of the roller on the cam slideway, avoid greater stress concentration, and improve the service life of the cam slideway.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a spring-tooth drum type peanut picking device. Background technique [0002] Peanut is an important oil crop and cash crop in the world and even in 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, peanu...
