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...
