Description

Technical Field

[0001] This utility model relates to the field of harvesting machine technology, and in particular to a jujube harvesting machine that is easy to maintain. Background Technology

[0002] A search revealed Chinese patent CN213991729U, which discloses a multi-arm telescopic jujube harvester that is easy to maintain. The machine includes a main body with a fixed block fixedly connected to its top. This invention utilizes a power supply device, a movable slot, an adjusting plate, a first connecting plate, a second connecting plate, a positioning slot, a positioning rod, a storage slot, a push rod, a pressing device, and a fixing device. The adjusting plate moves, causing the first connecting plate to move. The first connecting plate then moves, causing the positioning rod to disengage from the positioning slot behind the power supply device. This pulls the power supply device so that its front positioning slot is no longer in contact with the positioning rod, allowing for convenient disassembly of the power supply device. This solves the problem that existing multi-arm telescopic jujube harvesters use power supply equipment fixed to the machine body with bolts, making disassembly time-consuming and laborious when the power supply malfunctions. This easily maintainable multi-arm telescopic jujube harvester offers convenient disassembly and maintenance.

[0003] The aforementioned patent has the following shortcomings: While the patent facilitates the quick installation and disassembly of the power supply device, which greatly simplifies the operation for maintenance personnel, it places the power supply device on the outside of the machine body, exposing it to the external environment. During the harvesting process, external branches and other impurities may damage the power supply device, and it fails to provide real-time and effective protection. This design not only increases the risk of damage to the power supply device but may also negatively impact the subsequent harvesting process of the jujube. Therefore, it is urgent to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a jujube-picking machine that is easy to maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A jujube-picking machine that is easy to maintain includes a machine body. A protective box is located at one top end of the machine body. A power supply device is located inside the protective box. A removal mechanism is located on one side of the protective box for easy removal and maintenance of the power supply device. The removal mechanism includes trapezoidal grooves on both sides of the protective box's interior. Trapezoidal sliders slide inside each of the two trapezoidal grooves. A common fixing plate is fixed to the top of the two trapezoidal sliders. A dustproof plate is fixed to one end of the fixing plate. An insert is fixed to the top of the dustproof plate near the protective box. One end of the insert is arc-shaped, and the other end of the insert has a through hole. A slot is located at the top of one end of the protective box, and the insert is fitted to the slot. A fixing frame is fixed to one top end of the protective box. A hole is formed between the top of the fixing frame and the top of its inner wall. A limiting rod slides within the hole, and the bottom of the limiting rod passes through the top of the slot's inner wall and fits into the through hole. The limiting rod is inserted into the through hole to limit the position of the dustproof plate.

[0006] Preferably, one end of a spring is fixed to the top of the inner wall of the fixing frame, the other end of the spring is fixed to the top of the protective box, and the spring is located on the outer surface of the limiting rod.

[0007] Preferably, one end of the dustproof plate is fixed with a handle, and the top of the fixed plate is provided with a fixing mechanism for fixing the power supply device.

[0008] Preferably, the fixing mechanism includes a fixing platform fixed to the top of the fixing plate. Limit frames are fixed at the four corners of the top of the fixing platform. The inner wall of the fixing platform is provided with an installation groove, and the same bidirectional lead screw is rotatably connected to both sides of the inner wall of the installation groove. The outer walls of both sides of the bidirectional lead screw are provided with matching sliding blocks. The top sides of the inner wall of the installation groove are provided with communicating through grooves. The tops of the two sliding blocks are fixed with connecting blocks, and the two connecting blocks are fixed with clamping plates through the through grooves. The two clamping plates can clamp and fix the power supply device and facilitate disassembly.

[0009] Preferably, a knob is fixed at one end of the bidirectional lead screw, and a ratchet is fixed at the other end of the bidirectional lead screw. A pawl is rotatably connected to one side of the top of the fixed platform via a torsion spring, and the pawl engages with the ratchet.

[0010] Preferably, the limiting frame has grooves at both ends, and both ends of the two clamping plates are rotatably connected to rollers, which are slidably disposed inside the grooves.

[0011] Preferably, the top of the machine body is provided with a collection basket, the bottom two sides of the machine body are equipped with tracks, and the other end of the top of the machine body is equipped with a telescopic harvesting arm.

[0012] The beneficial effects of this utility model are as follows: 1. Due to the adoption of a removal mechanism, the limiting rod is moved away from the through hole, and then the dustproof plate can be removed from the inside of the protective box using the handle. This moves the fixing plate and the fixing platform out together. The power supply device is then placed on top of the fixing platform, and the power supply device is quickly installed using two clamping plates. The fixing platform is then pushed into the protective box using the dustproof plate, and the limiting rod will re-insert into the through hole to limit the dustproof plate, thus achieving the effect of protecting the power supply device. The fixing plate allows the power supply device to be easily removed for maintenance. The dustproof plate prevents external dust from entering the protective box, and the holes in the dustproof plate allow for heat dissipation of the power supply device, thereby improving the safety of the equipment and saving maintenance time. It is highly practical. Attached Figure Description

The top of the protective box 3 is fixed with a fixing bracket 5. The top of the fixing bracket 5 and the top of the inner wall have a through hole, and a limiting rod 501 is slidably installed in the hole. The bottom of the limiting rod 501 passes through the top of the inner wall of the slot 308 and is adapted to the through hole 307. The limiting rod 501 is inserted into the through hole 307 to limit the dustproof plate 301.

[0017] In this utility model, one end of a spring 502 is fixed to the top of the inner wall of the fixing frame 5, the other end of the spring 502 is fixed to the top of the protective box 3, and the spring 502 is located on the outer surface of the limiting rod 501.

[0018] In this utility model, a handle 304 is fixed to one end of the dustproof plate 301, and a fixing mechanism for fixing the power supply device 401 is provided on the top of the fixing plate 302.

[0019] In this utility model, the fixing mechanism includes a fixing platform 4 fixed to the top of the fixing plate 302. The four corners of the top of the fixing platform 4 are fixed with limit frames 402. The inner wall of the fixing platform 4 is provided with an installation groove, and the two sides of the inner wall of the installation groove are rotatably connected to the same bidirectional lead screw 406. The outer walls of both sides of the bidirectional lead screw 406 are provided with matching sliding blocks 407. The top two sides of the inner wall of the installation groove are provided with communicating through grooves 403. The top of the two sliding blocks 407 are fixed with connecting blocks 409, and the two connecting blocks 409 are fixed with clamping plates 410 through the through grooves 403. The two clamping plates 410 can clamp and fix the power supply device 401 and facilitate disassembly.

[0020] In this utility model, a knob 408 is fixed to one end of the bidirectional lead screw 406, and a ratchet 404 is fixed to the other end of the bidirectional lead screw 406. A pawl 405 is rotatably connected to one side of the top of the fixed platform 4 via a torsion spring, and the pawl 405 meshes with the ratchet 404. The ratchet 404 and the pawl 405 can limit the bidirectional lead screw 406 to prevent loosening.

[0021] In this utility model, the two ends of the limiting frame 402 are provided with sliding grooves 412, and the two ends of the two clamping plates 410 are rotatably connected with rollers 411, and the rollers 411 are respectively slidably disposed inside the sliding grooves 412.

[0022] In this utility model, a collection basket 2 is provided on the top of the machine body 1, and tracks 101 are installed on both sides of the bottom of the machine body 1. A telescopic picking arm 102 is installed on the other end of the top of the machine body 1.

[0023] Working principle: In use, first pull the limit rod 501. The limit rod 501 will move away from the through hole 307 and release the limit on the insertion block 306. Then pull the handle 304. The handle 304 will drive the fixing plate 302 to move. The fixing plate 302 will drive the trapezoidal slider 303 to slide inside the trapezoidal groove 309 and move the fixing plate 302 out. Then move the fixing platform 4 out from inside the protective box 3. Then place the power supply device 401 on top of the fixing platform 4. Then turn the knob 408. The knob 408 will drive the bidirectional lead screw 406 to rotate and drive the two sliding blocks 407 with sliding sleeves to move closer to each other. The sliding blocks 407 will drive the connecting blocks 409 to move closer to each other and drive the clamping plate 410 to move. The two clamping plates 410 will drive the rollers 411 at both ends to roll in the groove 412 respectively, and can only restrict the movement of the clamping plates 410 towards and away from each other. At this time, the two clamping plates 410 will supply power. The bottom sides of the device 401 are clamped and fixed, and the power supply device 401 is quickly installed. Then, the ratchet 404 engages with the pawl 405 to prevent the double-ended screw 406 from rotating and causing loosening. Then, the wiring terminal of the power supply device 401 is connected to the wiring terminal of the machine body 1. Then, the dustproof plate 301 drives the fixing plate 302 into the interior of the protective box 3 to protect the power supply device 401. The dustproof plate 301 drives the insertion block 306 into the slot 308. The arc surface of the insertion block 306 first contacts the bottom of the limiting rod 501 and squeezes it. Then, the bottom of the limiting rod 501 moves to the top of the insertion block 306 until it is inserted into the through hole 307, which limits the dustproof plate 301. This achieves the effect of convenient disassembly and maintenance of the power supply device 401, and provides protection for the power supply device 401 when it is working, increasing the stability of the power supply device 401 during operation.

[0024] It should be noted that the telescopic harvesting arm 102, power supply device 401, and track 101 are all existing technologies, well-known to those skilled in the art, and therefore will not be described in detail. Before use, the operator must conduct a comprehensive inspection of the jujube harvester, including the engine, power supply device 401, telescopic harvesting arm 102, and track 101, to ensure the equipment is operating normally. The harvester should then be driven into the orchard, using GPS or a navigation system to find the optimal operating path. Before entering the orchard, obstacles such as low branches and stones should be observed to ensure safe driving. Then, based on the height of the jujube trees and the ripeness of the fruit, the telescopic harvesting arm 102 should be powered by the power supply device 401. The machine supplies power, then adjusts the height, speed, and picking force of the telescopic picking arm 102 to achieve the best picking effect. The mature jujubes are then picked from the tree by vibration, scraping, or clamping. The fallen jujubes are then manually placed into the collection basket 2. After harvesting, the machine is driven back to the designated collection point or loading area, and the jujubes in the collection basket 2 are unloaded into containers for processing or transportation. After harvesting, the machine is cleaned to remove residual jujubes and impurities to prevent equipment corrosion. The power supply device 401 is then quickly disassembled and recharged for future use. This is the process of the jujube picking machine in the jujube harvesting production system.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
