Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a jujube harvesting and collecting machine. Background Technology

[0002] Jujube harvesting is one of the most labor-intensive and time-consuming operations. The high labor demand for jujube harvesting leads to increased costs. Mechanized harvesting can reduce growers' costs and significantly reduce labor. Existing vibratory harvesting is the most widely used method in large-scale production, achieving efficient harvesting, but it has limitations such as high collection difficulty, high tree damage rate, and inability to harvest jujubes on the ground. Manual picking is prone to causing cuts and bruises; jujubes falling to the ground due to the impact are damaged and prone to rotting, and are also unsanitary. Furthermore, manual harvesting is inefficient, and labor costs have been increasing year by year. Therefore, researching a jujube harvesting and collection machine to solve the existing problems of jujube harvesting and collection is particularly important. Summary of the Invention

[0003] The purpose of this invention is to provide a jujube harvesting and collecting machine to solve the problems of time-consuming, labor-intensive, and inefficient jujube harvesting and collecting methods.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a jujube picking and collecting machine, comprising a first side frame and a second side frame, wherein a jujube clamping and vibration mechanism is provided on the inner side of the first side frame or the second side frame, and the first side frame and the second side frame are detachably connected together through two connectors; a jujube collecting mechanism is provided on both the first side frame and the second side frame, and multiple cleaning mechanisms are installed at the bottom of the first side frame and the second side frame, wherein an air suction pipe is connected to the jujube collecting mechanism, and a fan is mounted on the air suction pipe; a pair of moving wheels are installed at the bottom of both the first side frame and the second side frame, and the moving wheels are driven by a first motor.

[0005] As a preferred embodiment of the present invention, the jujube clamping vibration mechanism includes a vibration arm bracket, a mechanical arm is hinged to the vibration arm bracket, a mechanical claw is provided at the drive end of the mechanical arm, and a vibrator is provided inside the mechanical arm.

[0006] As a preferred technical solution of the present invention, the connector includes a cross buckle and a hydraulic cylinder disposed on the side of the first frame and a slot disposed on the side of the second frame that matches the cross buckle. The telescopic end of the hydraulic cylinder is located inside the cross buckle. Telescopic plates are telescopically inserted on all four sides of the cross buckle. The telescopic plates are hinged to the telescopic end of the hydraulic cylinder. A sensor is disposed on the front side of the slot.

[0007] As a preferred embodiment of the present invention, the jujube collecting mechanism includes a collecting box. A pair of second motors are provided on the side of the collecting box. The drive end of the second motors is connected to a telescopic rod and a support rod. The drive ends of the two telescopic rods are connected to folding cloth support rods. Cloth bags are installed on the folding cloth support rods and the two support rods. A third motor is provided on the lower side of the collecting box.

[0017] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 and Figure 2 As shown, a jujube picking and collecting machine of the present invention includes a first side frame 1 and a second side frame 3. A jujube clamping and vibration mechanism 7 is provided on the inner side of the first side frame 1 or the second side frame 3. The first side frame 1 and the second side frame 3 are connected together in a detachable manner through two connectors 8. A jujube collecting mechanism 2 is provided on both the first side frame 1 and the second side frame 3. Multiple cleaning mechanisms 5 are installed at the bottom of the first side frame 1 and the second side frame 3. An air suction pipe 4 is connected to the jujube collecting mechanism 2. A fan is installed on the air suction pipe 4. A pair of moving wheels 6 are installed at the bottom of both the first side frame 1 and the second side frame 3. The moving wheels 6 are driven by a first motor.

[0020] During operation, the first motor drives the moving wheel 6 forward. When the jujube tree passes the first connector 8, the connector 8 is in the open state. After the main trunk of the jujube tree passes through, the connector 8 locks back in place. Then, the jujube-clamping vibration mechanism 7 clamps the branches of the jujube tree and vibrates them. At this time, the jujubes fall from the jujube tree into the jujube-collecting mechanism 2 for storage. Simultaneously, the fan sweeps up the jujubes that have fallen to the ground and sucks them into the jujube-collecting mechanism 2 through the suction pipe 4. After the jujubes have been collected, the jujube-clamping vibration mechanism 7 releases the jujube tree. As the moving wheel 6 moves, the jujube tree comes into contact with the second connector 8, which is in the open state. The jujube tree passes through the second connector 8, and after passing through, the second connector 8 locks back in place.

[0021] Example 2

[0022] like Figure 3As shown, in a jujube picking and collecting machine of the present invention, the jujube clamping vibration mechanism 7 includes a vibration arm support 701, a mechanical arm 702 is hinged on the vibration arm support 701, a mechanical claw 703 is provided at the drive end of the mechanical arm 702, and a vibrator is provided inside the mechanical arm 702.

[0023] The position of the mechanical claw 703 can be adjusted by the robotic arm 702 so that the mechanical claw 703 can hold the jujube tree.

[0024] like Figure 4 and Figure 5 As shown, in a jujube picking and collecting machine of the present invention, the connector 8 includes a cross buckle 801 and a hydraulic cylinder disposed on the side of the first side frame 1, and a slot 803 disposed on the side of the second side frame 3 that matches the cross buckle 801. The telescopic end of the hydraulic cylinder is located inside the cross buckle 801. Telescopic plates 802 are telescopically inserted on all four sides of the cross buckle 801. The telescopic plates 802 are hinged to the telescopic end of the hydraulic cylinder. A sensor 804 is disposed on the front side of the slot 803.

[0025] The cross-shaped latch 801 is inserted into the slot 803. When the telescopic end of the hydraulic cylinder extends, it pushes out the telescopic plate 802 on the cross-shaped latch 801, which then locks inside the port of the slot 803. At this time, the connector 8 is in a locked state. When the telescopic end of the hydraulic cylinder retracts, the telescopic plate 802 retracts and is no longer locked at the port of the slot 803. At this time, the connector 8 is in an unlocked state. When the jujube tree passes through, it can pass between the cross-shaped latch 801 and the slot 803. The sensor 804 is used to detect the position of the jujube tree so as to drive the hydraulic cylinder to achieve the corresponding movement.

[0026] Example 3

[0027] like Figures 6 to 9 As shown, in a jujube harvesting and collecting machine of the present invention, the jujube collecting mechanism 2 includes a collecting box 201. A pair of second motors 207 are provided on the side of the collecting box 201. The driving end of the second motors 207 is connected to a telescopic rod 206 and a support rod 205. The driving ends of the two telescopic rods 206 are connected to a folding cloth support rod 204. A cloth bag 202 is installed on the folding cloth support rod 204 and the two support rods 205. A third motor 211 is provided on the lower side of the collecting box 201. The driving end of the third motor 211 is connected to a small sprocket 210. The small sprocket 210 is connected to a large sprocket 209 through chain transmission. Multiple conveying rods 208 are provided on the chain. A storage box 203 is provided on the side of the collecting box 201. The upper inlet of the storage box 203 is located below the conveying rods 208.

[0028] The second motor 207 is started, which drives the folding cloth support rod 204 and other movements to open the cloth bag 202, so as to collect as many fallen dates as possible, so that the dates fall into the collection box 201 and then onto the conveyor rod 208 of the chain. The third motor 211 is started, which drives the large sprocket 209 to rotate through the chain via the small sprocket 210, so that the chain can rotate in a cycle, so that the dates can be transported to the storage box 203 for collection via the conveyor rod 208.

[0029] The suction pipe 4 is installed on the side of the storage box 203. The jujubes that fall to the ground can be sucked into the storage box 203 by the action of the fan.

[0030] like Figure 10 As shown, the cleaning mechanism 5 includes a sweeping disc 501, and multiple rubber strips 502 are provided at the lower end of the sweeping disc 501. The sweeping disc 501 is driven by a fourth motor.

[0031] The fourth motor drives the sweeping disc 501 to rotate, and the rubber strip 502 can push the jujubes that have fallen to the ground out, so as to collect the jujubes that have fallen to the ground smoothly.

[0032] Compared with existing jujube picking devices, this invention uses an integrated mechanical structure to save space. The vibration of the mechanical claw is transmitted from the trunk to the branches and jujubes, avoiding damage to the jujubes during picking caused by direct contact between the machine and the jujubes. It also ensures that the picking machine does not damage the jujube trees during movement. It has the following features: (1) It can collect jujubes on the tree and jujubes that have fallen to the ground, avoiding waste caused by rotting due to uncollected jujubes. (2) An elastic cloth bag is provided on the outside of the collection box to prevent the jujubes from being damaged by gravity. (3) A foldable cloth bag bracket is used, and the telescopic rod can be retracted when moving in the jujube orchard. The whole device is small and convenient. (4) The cloth bag has a large extension area, which can catch the jujubes that are shaken down to the maximum extent, preventing the jujubes from falling to the ground and causing waste. (5) The gap setting of the conveyor belt can separate the fallen jujubes and broken leaves, avoiding the accumulation of broken leaves and jujubes. (6) A push-pull plate is provided in the storage box. When the push-pull plate is pulled out, the jujubes in the storage box can fall into the prepared packing bag. (7) The sweeping device is equipped with a sweeping disc, which can sweep the scattered jujubes into the middle, and then collect the jujubes on the ground through the air suction device. (8) The harvester is equipped with an air suction mechanism, which can collect the jujubes that have fallen to the ground. (9) The upper surface of the collection box is set as a slope, which allows the jujubes that have fallen onto the vehicle to slide into the foldable cloth bag. (10) The connector includes a hydraulic cross buckle device, a slot, and a telescopic plate. It can be opened after the sensor detects the jujube tree and closed after passing the jujube tree, ensuring that the harvester does not damage the jujube tree during the movement.
