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] Embodiment 1: as figure 1 As shown, a kind of shovel tooth-elastic tooth drum combined peanut picking device of the present invention comprises picking up shovel teeth 1, a drum guard plate 6, a picking drum, a drum slideway 2 and a side plate, and the central axis 7 of the picking drum passes through two The left and right side plates 10 and 14 on the side are mounted on the left and right bearing housings 9 and 15 respectively, and the picking-up spring teeth 5 are evenly spaced on the spring-tooth shaft 12 of the pick-up drum, and rollers are arranged between the 5 adjacent pick-up spring teeth. Guard plate 6, at the front end of travel, arc-shaped pick-up shovel teeth 1 with the same structure are installed at the same position on each of the drum guard plates 6 to form a row of shovel teeth; Move forward, scoop up the peanut plants drying on the ground from the ground, make the peanut plants leave the ground and move up to a certain height along the arc-shaped shov...

Embodiment 2

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

[0057] The phase angles corresponding to the three stations of lifting, pushing and emptying are respectively β 1 ~β 3 , where the initial lift angle θ of the lift station 1 is 10-60°, the initial lift angle θ 1 is the angle between the pick-up tooth 5 and the Y-axis of the drum along the forward direction of the pick-up device, the three phase angles are β1=...

Embodiment 3

[0066] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the angle θ between the installation tangent point of the pick-up shovel teeth 1 and the guard plate 6 in this embodiment is the same as that of the central axis, and the y-coordinate of the central axis is 45°. °, the radius R2 of the shovel tooth base circle is 42mm, and the corresponding central angle α2 is based on the fourth quadrant as the starting point, relative to the starting point central angle is a 116° segment involute, α 0 =45,α n = 161°; α 0 is the starting angle of the tooth involute, α n is the cut-off angle of the tooth involute.

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

[0068] Such as Figure 10 As shown, in this example: in the same section, O is the center of the central axis, and its coordinate system is (X, Y) as the basic coordinate system; O 1 for The center ...

Abstract

The invention discloses a shovel tooth and elastic tooth roller combined type peanut pickup device, and belongs to the technical field of agricultural machinery. The shovel tooth and elastic tooth roller combined type peanut pickup device comprises picking shovel teeth, roller protection plates, a picking roller, a roller sliding way and side plates; a center shaft of the picking roller penetratesthrough the side plates at the two sides to be installed on bearing pedestals, picking elastic teeth are evenly arranged on an elastic tooth shaft of the picking roller at intervals, and the roller protection plates are arranged between the adjacent picking elastic teeth; 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 to form a row of shovel teeth; and the roller sliding way is fixedly installed in one side plate and is in sliding connection with the elastic tooth shaft on the picking roller. According to the pickup device, the peanut plants are shoveled up through the shovel teeth; the picking roller rotates along the roller sliding way, and the elastic teeth rotatearound the center shaft along with the roller and periodically and repeatedly swing due to the limitation of the roller sliding way, so that actions of lifting, pushing and returning to a station by the elastic teeth are realized; and the impact of the roller on a cam sliding way can be effectively reduced, large stress concentration is avoided, and the service life of the cam sliding way is prolonged.

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 economic crop 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 relies on imports o...
