Description

Technical Field

[0001] This utility model relates to the technical field of fruit harvesting devices, specifically an electric fruit harvesting device. Background Technology

[0002] In orchards with densely fruited crops such as jujubes and apples, manual harvesting requires long periods of climbing ladders or repeatedly bending over, resulting in enormous physical exertion for fruit farmers. There is an urgent need for efficient, safe, and low-cost fruit harvesting technology, which has led to the development of fruit harvesting devices.

[0003] A search revealed a utility model patent with Chinese patent publication number CN203416631U, which discloses a simple fruit-collecting device, including a support column, two semi-circular fruit-collecting devices, and a connecting shaft. The two semi-circular fruit-collecting devices are connected and rotated by the connecting shaft, and the support column is located below the semi-circular fruit-collecting devices. Each semi-circular fruit-collecting device includes a fruit-collecting net on its bottom surface and a baffle plate that surrounds the fruit-collecting net. A recessed branch clamp is provided in the middle of one side of each semi-circular fruit-collecting device.

[0004] When the above-mentioned device is in use, in addition to the fruit, a large number of leaves and a small number of branches are knocked off. Therefore, after collection, they need to be sorted again, which greatly increases the workload and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide an electric fruit harvesting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric fruit harvesting device, including a wheelbarrow, with a mounting base fixedly connected inside the wheelbarrow. A collecting component is provided on the top of the mounting base. The collecting component includes a connecting seat one fixedly connected to the outer wall of the top of the mounting base. A connecting seat two is hinged to one side of the outer wall of the connecting seat one. Both connecting seats one and two are provided with a cleaning component. The two cleaning components have identical structures and are symmetrically arranged. The cleaning component includes a connecting column fixedly connected to the outer wall of one side of the connecting seat one. A rotary joint is fixedly connected to one bottom end of each connecting column. An air outlet pipe is coaxially fixed to the rotating end of each rotary joint. Several nozzles distributed at equal intervals are fixedly connected to the outside of the air outlet pipe. The mounting base is provided with an air supply structure, and a shaking component is provided inside the mounting base.

[0007] The system can continuously apply a changing airflow from below the receiving net, ensuring that most impurities within the net are removed and eliminated from subsequent sorting processes, thus reducing labor. The blower installed on the outside of the wheelbarrow is activated, and the airflow generated by the blower is introduced into the rotary joint through a pipe. After passing through its internal channel, it enters the exhaust pipe from the rotating end outlet and is finally sprayed outwards through several nozzles on the outside of the exhaust pipe. Because the nozzles' spray direction is tangential to the exhaust pipe, the airflow generates a tangential reaction force after being ejected. Driven by these multiple reaction forces, the exhaust pipe rotates continuously. The exhaust pipe on the left rotates counterclockwise, and the exhaust pipe on the right rotates clockwise. If leaves approach the receiving net, the rotating airflow can drive the leaves outwards through the holes in the net.

[0008] As a further preferred embodiment of this technical solution, the air supply structure includes a blower fixedly installed on the outer wall of one side of the mounting base, and the air outlet of the blower is connected to the air inlets of two rotary joints through a pipe.

[0009] As a further preferred embodiment of this technical solution, the air outlet direction of the nozzle is tangent to the air outlet pipe.

[0010] As a further preferred embodiment of this technical solution, a support ring is fixedly connected to the top outer wall of both connecting seat one and connecting seat two, and a receiving mesh is fixedly connected inside each of the two support rings. An electric push rod one is fixedly installed on one side outer wall of the mounting seat, and a drive seat is fixedly connected to the output end of the electric push rod one. Two columnar protrusions are fixedly connected to the top outer wall of the drive seat. The edge of the support ring fixed at the top of the connecting seat two is located between the two columnar protrusions. A sleeve groove is opened on the outer wall of the side of the two support rings that are close to each other, and a sponge block is fixedly connected inside each of the two sleeve grooves.

[0011] When the electric push rod initially extends, its output end drives the drive seat to slide outward along the mounting base. The protrusion on the top of the drive seat, near the electric push rod, contacts the inner wall of the movable support ring, thereby pushing the support ring and the connected seat to flip. Then, the pushing device positions the fruit tree between the two support rings. The electric push rod is then controlled to drive the drive seat to reset, and the protrusion on its top, away from the electric push rod, contacts the outside of the movable support ring, thus pushing it to merge with the other support ring. Since the whole composed of the two support rings is inclined and has an opening at the bottom, it ensures that after the fruit is caught, it will slide down the slope in time, avoiding damage from collisions and preventing the device from being crushed by excessive weight.

[0012] As a further preferred embodiment of this technical solution, the shaking assembly includes a mounting frame slidably connected inside the mounting base. An electric push rod II is fixedly installed inside the mounting frame. A pull rod is fixedly connected to the end of the mounting frame away from the mounting base. A push rod adapted to the pull rod is fixedly connected to the output end of the electric push rod II. A transmission structure is provided at the end of the mounting frame located inside the mounting base for transmitting vibration to the mounting frame.

[0013] As a further preferred embodiment of this technical solution, the transmission structure includes a vibration motor fixedly installed on the outer wall of one side of the mounting frame, and a spring is fixedly connected to both sides of one end of the mounting frame located on the mounting base, and both springs are fixedly connected to the inner wall of one side of the mounting base.

[0014] As a further preferred embodiment of this technical solution, a sleeve is fixedly connected to the external support ring of the top of the first connecting seat, and a plug is fixedly connected to the end of the support ring at the top of the second connecting seat away from the mounting seat. The plug is arc-shaped, and the center of the plug coincides with the rotation axis of the support ring. A slot adapted to the plug is opened inside the sleeve.

[0015] This utility model provides an electric fruit harvesting device, which has the following beneficial effects: (1) By setting up a cleaning component, this utility model can continuously apply a continuously changing airflow from below the receiving net, so that most of the impurities in the receiving net can be cleaned to the outside, which can save the subsequent sorting process and reduce the amount of labor. The blower installed on the outside of the wheelbarrow is controlled to start. The airflow generated by the blower is introduced into the rotary joint through the pipe. After passing through its internal channel, it enters the air outlet pipe from the rotary end outlet. Finally, it is sprayed outward through several nozzles outside the air outlet pipe. Since the spray direction of the nozzle is tangential to the air outlet pipe, the airflow will generate a tangential reaction force after being sprayed out. Under the push of multiple reaction forces, the air outlet pipe will continue to rotate. The air outlet pipe on the left rotates counterclockwise and the air outlet pipe on the right rotates clockwise. If there are leaves close to the receiving net, the rotating airflow can drive the leaves outward through the holes of the receiving net.

[0016] (2) By setting up a collection component, the electric push rod is initially extended. The output end of the electric push rod drives the drive seat to slide outward along the mounting seat. The protrusion on the top of the drive seat near the electric push rod contacts the inner wall of the movable support ring, thereby pushing the support ring and the connecting seat connected to it to flip. Then the pushing device makes the fruit tree located between the two support rings. Then the electric push rod is controlled to drive the drive seat to reset. The protrusion on its top away from the electric push rod contacts the outside of the movable support ring, thereby pushing it to merge with the other support ring. Since the whole composed of the two support rings is inclined and has an opening at the bottom, it ensures that after the fruit is received, it will slide down the slope in time, avoiding the fruit from colliding with each other and being damaged, and also preventing the device from being crushed by excessive weight.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 2 , Figure 3 and Figure 5As shown, in this embodiment, an electric fruit harvesting device includes a wheelbarrow 2 (with a battery at the bottom for powering electrical appliances). A mounting base 1 is fixedly connected inside the wheelbarrow 2. A collecting component 3 is provided on the top of the mounting base 1. The collecting component 3 includes a connecting seat 301 fixedly connected to the outer wall of the top of the mounting base 1. A connecting seat 2 is hinged to one side of the outer wall of the connecting seat 301. Both the connecting seat 301 and the connecting seat 2 are provided with a cleaning component 4. The two cleaning components 4 have the same structure and are symmetrically arranged. The cleaning component 4 includes a connecting column 401 fixedly connected to one side of the outer wall of the connecting seat 301. A rotary joint 402 is fixedly connected to one bottom end of the connecting column 401. An air outlet pipe 403 is coaxially fixed to the rotating end of the rotary joint 402. Several nozzles 404 distributed at equal intervals are fixedly connected to the outside of the air outlet pipe 403. The mounting base 1 is provided with an air supply structure. A shaking component 5 is provided inside the mounting base 1.

[0020] The air supply structure includes a blower fixedly installed on the outer wall of one side of the mounting base 1. The blower outlet is connected to the air inlet of two rotary joints 402 through a pipe.

[0021] The air outlet direction of nozzle 404 is tangent to the air outlet pipe 403.

[0022] The blower installed on the outside of the control wheel 2 is started. The airflow generated by the blower is introduced into the rotary joint 402 through the pipe. After passing through its internal channel, it enters the air outlet 403 from the outlet of the rotating end. Finally, it is sprayed outward through several nozzles 404 on the outside of the air outlet 403. Since the air jet direction of the nozzles 404 is tangential to the air outlet 403, the airflow will generate a tangential reaction force after being sprayed out. Under the push of multiple reaction forces, the air outlet 403 will continue to rotate. The air outlet 403 on the left rotates counterclockwise, and the air outlet 403 on the right rotates clockwise. If there are leaves near the receiving net 303, the rotating airflow can drive the leaves outward through the holes of the receiving net 303.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, a support ring 302 is fixedly connected to the top outer wall of both connecting seat 1 301 and connecting seat 2. A receiving net 303 is fixedly connected inside each of the two support rings 302. An electric push rod 304 is fixedly installed on one side outer wall of mounting seat 1. A drive seat 305 is fixedly connected to the output end of the electric push rod 304. Two columnar protrusions are fixedly connected to the top outer wall of the drive seat 305. The edge of the support ring 302 fixed at the top of connecting seat 2 is located between the two columnar protrusions. A sleeve groove is opened on the outer wall of the side of the two support rings 302 that are close to each other. A sponge block 306 is fixedly connected inside each of the two sleeve grooves (which can adapt to tree trunks of different shapes and prevent fruits from falling to the ground through the sleeve grooves).

[0024] The electric push rod 304 extends, and its output end drives the drive seat 305 to slide outward along the mounting base 1. The protrusion on the top of the drive seat 305 near the electric push rod 304 contacts the inner wall of the movable support ring 302, thereby pushing the support ring 302 and the connected seat 301 to flip. Then, the push device positions the fruit tree between the two support rings 302. The electric push rod 304 is then controlled to drive the drive seat 305 to reset, and the protrusion on its top away from the electric push rod 304 contacts the outside of the movable support ring 302, thereby pushing it to merge with the other support ring 302. Since the whole composed of the two support rings 302 is inclined and has an opening at the bottom, it ensures that after the fruit is caught, it will slide down the slope in time, avoiding damage from collisions and preventing the device from being crushed by excessive weight.

[0025] like Figure 2 and Figure 4 As shown, the shaking assembly 5 includes a mounting bracket 501 slidably connected inside the mounting base 1. An electric push rod 503 is fixedly installed inside the mounting bracket 501. A pull rod 502 is fixedly connected to the end of the mounting bracket 501 away from the mounting base 1. A push rod adapted to the pull rod 502 is fixedly connected to the output end of the electric push rod 503. A transmission structure is provided at the end of the mounting bracket 501 located inside the mounting base 1 for transmitting vibration to the mounting bracket 501.

[0026] The transmission structure includes a vibration motor 505 fixedly installed on the outer wall of one side of the mounting bracket 501. A spring 504 is fixedly connected to both sides of one end of the mounting bracket 501 located on the mounting base 1. Both springs 504 are fixedly connected to the inner wall of one side of the mounting base 1.

[0027] During the wrapping process, the operator positions the tree trunk between the pull rod 502 and the push rod at the output end of the electric push rod 503, and controls the electric push rod 503 to extend, clamping the tree trunk with the pull rod 502 to achieve connection with the tree trunk. At this time, the operator controls the vibration motor 505 to start running, and with the cooperation of the spring 504, the mounting frame 501 begins to vibrate rapidly. The vibration is transmitted to the tree through the pull rod 502 and the push rod at the output end of the electric push rod 503, and the fruit on it will fall with the vibration.

[0028] like Figure 2 and Figure 3 As shown, a sleeve is fixedly connected to the external support ring 302 fixed at the top of the connector 1 301. A plug 307 is fixedly connected to the end of the top support ring 302 of the connector 2 away from the mounting base 1. The plug 307 is arc-shaped, and the center of the plug 307 coincides with the rotation axis of the support ring 302. A slot adapted to the plug 307 is opened inside the sleeve. When the two support rings 302 are combined, the plug will be inserted into the sleeve, which can prevent the ends of the two support rings 302 from being misaligned during use.

[0029] This utility model provides an electric fruit harvesting device, the specific working principle of which is as follows: When the device is working, the control electric push rod 304 begins to extend. The output end of the electric push rod 304 drives the drive seat 305 to slide outward along the mounting base 1. The protrusion on the top of the drive seat 305 near the electric push rod 304 contacts the inner wall of the movable support ring 302, thereby pushing the support ring 302 and the connecting seat 301 connected to it to flip. Then, the device is pushed so that the fruit tree is located between the two support rings 302. Then, the control electric push rod 304 drives the drive seat 305 to reset. The protrusion on its top away from the electric push rod 304 contacts the outside of the movable support ring 302, thereby pushing it to merge with the other support ring 302. Since the whole composed of the two support rings 302 is inclined and has an opening at the bottom end, it is ensured that after the fruit is received, it will slide down the slope in time, avoiding the fruit from colliding with each other and being damaged, and also preventing the device from being crushed by excessive weight.

[0030] During the wrapping process, the operator positions the tree trunk between the pull rod 502 and the push rod at the output end of the electric push rod 503, and controls the electric push rod 503 to extend, clamping the tree trunk with the pull rod 502 to achieve connection with the tree trunk. At this time, the operator controls the vibration motor 505 to start running, and with the cooperation of the spring 504, the mounting frame 501 begins to vibrate rapidly. The vibration is transmitted to the tree through the pull rod 502 and the push rod at the output end of the electric push rod 503, and the fruit on it will fall with the vibration.

[0031] During this period, the blower installed on the outside of the control wheel 2 is started. The airflow generated by the blower is introduced into the rotary joint 402 through the pipe. After passing through its internal channel, it enters the air outlet 403 from the rotary end outlet. Finally, it is sprayed outward through several nozzles 404 on the outside of the air outlet 403. Since the air jet direction of the nozzles 404 is tangential to the air outlet 403, the airflow will generate a tangential reaction force after being sprayed out. Under the push of multiple reaction forces, the air outlet 403 will continue to rotate. The air outlet 403 on the left rotates counterclockwise, and the air outlet 403 on the right rotates clockwise. If leaves approach the receiving net 303, the rotating airflow can drive the leaves outward through the holes of the receiving net 303.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
