Embodiment 1

[0027] Embodiment 1: as figure 1 As shown, a kind of axial-flow peanut picking machine of the present invention comprises frame 19, motor 15, transmission device, fruit picking device, cleaning device, feeding port 10, stem row port 8 and discharge port 26, and described fruit picking The device comprises a fruit-picking cylinder 16, a concave screen 17 and a top cover 9, wherein the central axis 34 of the fruit-picking cylinder 16 is installed on the frame 19, the concave screen 17 is installed on the frame 19 and is located below the fruit-picking cylinder 16, and the top cover 9 is fixed. Positioned on the frame 19 above the fruit picking cylinder 16, the feeding port 10 and the stem opening 8 are fixed on both sides of the top cover 9, and the space surrounded by the concave screen 17 and the top cover 9 is the fruit picking room.

[0028] Such as figure 2 As shown, the fruit picking cylinder 16 includes a central axis 34, a fixed frame 30 arranged at both ends of the ce...

Embodiment 2

[0035] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the fruit picking rod 32 in this embodiment is an arc rod, and the angle α inclined to the central axis 34 is 15°. The included angle β between the fruit-picking tooth 31 and the normal direction of the contact point with the central axis 34 is 25, and the radial gap between the fruit-picking tooth 31 outer edge on the fruit-picking bar 32 and the concave screen 17 and the top cover 9 is 20mm. The bending angle γ at the end of the fruit picking teeth 31 is 75°. The anti-wrapping grass structure is provided with two rows of grass teeth 28 . The central angle of the arc of the concave screen 17 is 180°. Grass row tooth 28 is that the end bending angle θ is 125 °, and the angle η between the grass row tooth axis and the contact point normal direction of the main shaft is 25 °.

Embodiment 3

[0036] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the fruit picking rod 32 in this embodiment is a straight rod, and the angle α inclined to the central axis 34 is 20°. The included angle β between the fruit picking tooth 31 and the normal direction of the contact point with the central axis 34 is 30°, and the radial gap between the fruit picking tooth 31 outer edge on the fruit picking bar 32 and the concave screen 17 and the top cover 9 is 30mm. The bending angle γ at the end of the fruit picking teeth 31 is 90°. The anti-wrapping grass structure is provided with two rows of grass teeth 28 . The central angle of the arc of the concave screen 17 is 230°. The grass-discharging teeth 28 have an end bending angle θ of 145°, and the included angle η between the grass-discharging tooth axis and the contact point normal direction of the main shaft is 30°.

Abstract

The invention discloses an axial-flow type peanut picker, and belongs to the technical field of agricultural machinery. The axial-flow type peanut picker comprises a rack, a motor, a transmission device, a peanut picking device, a sorting device, a feeding port, a stem discharging port and a discharging port; the peanut picking device comprises a peanut picking roller, a concave grate and a top cover, wherein a central shaft of the peanut picking roller is installed on the rack, the concave grate is installed on the rack and located under the peanut picking roller, the top cover is fixed to the rack and located over the peanut picking roller, and a space formed by the concave grate and the top cover in an enclosing mode serves as a peanut picking chamber. According to the axial-flow type peanut picker, peanut seedling conveying in the axial direction and continuous peanut picking are achieved; peanut picking bent teeth are beneficial for grabbing peanut seedlings and keep a certain included angle with the generatrix of the roller, therefore, the peanut seedlings can be conveniently transmitted in the axial direction and successfully separated, and winding of the peanut seedlings to the peanut picking bent teeth is reduced; the peanut seedlings can be smoothly discharged out of the peanut picker and cannot be wound through an anti-winding device; the clean picking rate is high, the peanut breakage rate is low, peanut seedling winding and blocking are avoided, and the impurity containing rate of sorted peanut pods is low.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to an axial-flow peanut picker. Background technique [0002] Fruit picking is a necessary part of the peanut harvesting process, and it is also the main cause of peanut harvest loss. Mechanical fruit picking will cause missed picking and damage of peanut pods. The former directly leads to the loss of peanut pods, while the latter is due to the loss of intact shell protection of peanut kernels and the possibility of being infected with Aspergillus flavus during storage. Pods become moldy, leading to greater secondary losses. Due to different mechanical harvesting methods, there are significant differences in peanut plant traits and physical and mechanical properties during fruit picking, and there are also great differences in the structure, principle and performance of fruit picking devices. At the beginning of this century, my country began to study full-feed and ...
