Description

Mountain automatic Chinese prickly ash picking device TECHNICAL FIELD

[0002] The back-dragging type Chinese prickly ash picking machine is a device designed to be carried on the body of an operator by a back-carrying belt and to pick Chinese prickly ash by holding and dragging the collecting and conveying mechanism. The storage collecting device moves on the ground, thereby reducing the load pressure of the operator. The back-dragging type Chinese prickly ash picking machine usually comprises a power device (such as a small motor or an internal combustion engine), a picking head, a transmission mechanism, a collecting device, and a back-carrying frame and a back-carrying belt. When in use, the operator carries the back-dragging type Chinese prickly ash picking machine on the body, starts the power device to drive the picking head to work through the operation handle or the control device, so as to realize the rapid and efficient picking of Chinese prickly ash. The picked Chinese prickly ash is collected in a specific device for subsequent processing and storage. When picking Chinese prickly ash, the picker needs to use the picking machine to pick Chinese prickly ash.

[0003] The conventional Chinese prickly ash picking machine is inconvenient for quantitative picking of Chinese prickly ash. After each collection of Chinese prickly ash, additional time and effort are needed for re-sorting and metering, thereby interrupting the continuous picking process and increasing the overall working time, which is not conducive to the subsequent processing of Chinese prickly ash. Moreover, the conventional back-carrying type is to carry the storage mechanism on the operator's body, which increases the pressure on the operator.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Referring to FIGS. 1 to 6 of the present application, the mountain automatic pepper picking device according to the embodiments of the present application comprises:

[0029] The mobile storage mechanism 1 is internally connected with the dosing cylinder 12 sliding up and down, the storage amount in the dosing cylinder 12 is in proportional relationship with the downward movement of the dosing cylinder 12, and the mobile storage mechanism 1 is provided with the meter 7 for visually detecting the downward position of the dosing cylinder 12;

[0030] The back drag assembly 2 is connected with the mobile storage mechanism 1, and the back drag assembly 2 is worn on the staff and can drag the mobile storage mechanism 1 to move forward;

[0031] The collection conveying mechanism 3 is connected at one end to the mobile storage mechanism 1 and establishes a gas path communication relationship with the mobile storage mechanism 1, and the other end of the collection conveying mechanism 3 is provided with the collection box 34, and the materials in the collection box 34 can be conveyed by gas force into the mobile storage mechanism 1;

[0032] The cutting mechanism 4 is fixed on the collection box 34, and the cut materials of the cutting mechanism 4 are collected by the collection box 34.

[0033] In other embodiments, the mobile storage mechanism 1 comprises an outer cylinder 11, a quantitative cylinder 12, a buffer spring 13, a cover plate 14 and a lock catch assembly 15, the bottom of the outer cylinder 11 is rotatably connected with a walking wheel 16, one end of the back dragging assembly 2 is fixedly connected with the outer cylinder 11, a sliding groove 17 is vertically arranged on the inner side wall of the outer cylinder 11, a top of the quantitative cylinder 12 is provided with a frame 19 matched with the sliding groove, the buffer spring 13 is fixed on the frame 19 and used for supporting the downward movement of the quantitative cylinder 12, the cover plate 14 is detachably connected with the top of the outer cylinder 11 through the lock catch assembly 15, and one end of the collection and conveying mechanism 3 is connected with and communicated with the cover plate 14.

[0034] The outer cylinder 11 serves as the main frame of the whole mobile storage mechanism 1, which not only provides a stable mounting space for the internal components, but also plays a good protective role for the stored Zanthoxylum bungeanum, effectively resisting external collision and extrusion and ensuring the integrity of the Zanthoxylum bungeanum.

[0035] It should be noted that the frame can block the gap between the quantitative cylinder and the inner wall of the outer cylinder, ensuring that the Zanthoxylum bungeanum falls into the quantitative cylinder. The frame can smoothly slide up and down by cooperating with the sliding groove of the outer cylinder through the clamping block, thereby adapting to the increasing weight of the Zanthoxylum bungeanum and also playing a certain sealing role to reduce the scattering of the Zanthoxylum bungeanum during storage. The buffer spring 13 is gradually compressed when the quantitative cylinder bears the weight of the Zanthoxylum bungeanum, thereby playing a buffering and supporting role. When the Zanthoxylum bungeanum is taken out and the weight is reduced, the elastic force of the buffer spring 13 can push the frame and the quantitative cylinder back to the original position, thereby preparing for the next round of storage. The support plate 18 provides a firm fixing point for the bottom of the buffer spring 13, ensuring that the buffer spring 13 maintains a stable direction and force during extension and contraction, avoiding the occurrence of spring deviation or instability. The design of the quantitative cylinder 12 can accurately control the amount of Zanthoxylum bungeanum stored each time, making the picking work more standardized and standardized.

[0036] The operator can easily open or close the cover plate through the knob handle on the cover plate, which is simple and quick to operate and improves work efficiency.
