Description

Technical Field

[0001] This invention belongs to the field of fruit harvesting technology, and in particular relates to a portable fruit harvesting machine and its usage method. Background Technology

[0002] In the field of fruit picking, with the development of agricultural modernization, the demand for efficient and convenient picking equipment is increasing. Traditional fruit picking methods mostly rely on manual climbing or the use of simple tools, which is not only labor-intensive but also inefficient. For example, when picking apples, pears and other fruits in orchards, fruit farmers often need to hold long poles or ladders to pick the fruits one by one from the high places. This not only consumes a lot of time and energy but is also prone to damaging the fruit trees due to improper operation. In order to improve this situation, various fruit picking equipment has gradually appeared on the market.

[0003] For example, Chinese patent CN109392458B discloses a fruit-harvesting device, including a vibrating part and a harvesting part, wherein the vibrating part and the harvesting part are connected by a spring; the vibrating part generates vibrational force and transmits the vibrational force to the harvesting part, and the harvesting part contacts the fruit to be harvested and separates the fruit from the tree under the action of its vibrational force. The device provided in this application has a simple and reasonable structure and is easy to install and use. It abandons the traditional method of converting circular motion into linear motion to generate vibrational force, and directly uses a bent shaft to generate vibrational force through circular motion, greatly improving the vibration generation efficiency. It can generate the vibrational force required for fruit harvesting without the need for a high-horsepower drive motor. Due to the small size and low energy consumption of the drive motor, the overall weight of the device is light, which can greatly reduce the workload of workers during use. This device also has the advantages of wide applicability and good harvesting effect. It is worthy of widespread promotion and use.

[0004] However, the above solution lacks convenient telescopic adjustment function, and the extension length of the picking head is fixed, making it difficult to flexibly adapt to the picking needs of fruit trees of different heights or fruits in different positions on the same fruit tree. This leads to operators having to frequently move their positions or even use climbing tools to pick fruits at high places, increasing labor intensity and reducing overall picking efficiency.

[0005] To address these issues, we provide a portable fruit harvester and its usage method. Summary of the Invention

[0006] The purpose of this invention is to provide a portable fruit harvester and its method of use. By combining a retractable and adjustable structure with a vibrating harvesting head, the existing problems of limited harvesting height and low efficiency are solved.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a portable fruit picking machine and its method of use, including a shell, the shell including a control part, an upper mounting part, a lower mounting part, a motor mounting part and a grip part, the upper mounting part and the lower mounting part are arranged in parallel to each other, and both the upper mounting part and the lower mounting part are connected to the front end of the control part, and the grip part is located between the control part and the motor mounting part; The vibration assembly includes a drive motor fixedly connected to the motor mounting part, an outer sliding sleeve movably sleeved in the upper mounting part, and a prism-shaped drive rod rotatably connected inside the control part.

The telescopic assembly includes a threaded sleeve rotatably connected to the interior of the lower mounting portion, a screw threaded inside the threaded sleeve, a fixing block fixedly connected to the exterior of the outer sliding sleeve, and the free end of the screw fixedly connected to the exterior of the fixing block.

[0008] The invention is further configured such that a guide groove is provided at the other end of the swing head, and a rotating disk is fixedly connected to the end of the inner sliding sleeve away from the drive motor. A guide wheel that rolls in the guide groove is rotatably connected to the side of the rotating disk away from the inner sliding sleeve.

[0009] The invention is further configured such that a rotating shaft is rotatably connected inside the control unit, a driven gear is fixedly connected to the outside of the rotating shaft, a driving gear that meshes with the driven gear is fixedly connected to the outside of the drive rod, a prism-shaped guide post is fixedly connected to the end of the rotating shaft away from the drive motor, a connecting sleeve is movably sleeved on the outside of the guide post, and a connector adapted to the connecting sleeve is fixedly connected to the end of the threaded sleeve facing the drive motor.

[0010] The invention is further configured such that a lever is fixedly connected to the outside of the connecting sleeve, and an insertion port is provided inside the lever; a guide frame communicating with the control unit is fixedly connected to the bottom of the control unit, and the lever is slidably connected to the inside of the guide frame; a spring pin with a wedge-shaped movable end is fixedly connected to the outside of the guide frame, and the movable end of the spring pin is inserted into the inside of the insertion port; a push spring is movably sleeved on the outside of the guide post, and the push spring is located between the connecting sleeve and the rotating shaft.

[0011] The invention is further configured to include a power supply component, which includes a battery pack for supplying power to the entire device. A vent frame is fixedly connected to the back of the battery pack, and a sponge pad is fixedly connected to the side of the vent frame facing away from the battery pack.

[0012] The present invention is further configured such that the picking head includes a fixed base fixedly connected to the end of the swing head away from the drive motor, and the side of the fixed base away from the swing head is fixedly connected to two symmetrically distributed V-shaped hooks and a top rod located between the two V-shaped hooks.

[0013] The invention is further configured such that a protective sleeve is fixedly fitted onto the outside of the swing head and the outer sliding sleeve, and the swing seat is located inside the protective sleeve.

[0014] The invention is further configured such that a control trigger for controlling the speed of the drive motor is installed at one end of the control unit facing the drive motor, and a reversing switch for controlling the rotation direction of the drive motor is installed outside the control unit.

[0015] The invention is further configured such that a shoulder strap is fixedly connected to the outside of the control unit, and a rubber sleeve is fixedly fitted to the outside of the grip unit.

[0016] This invention also provides a method for using a portable fruit harvester, which harvests fruit according to the following steps: S1. Wear the battery pack on your back, then put the shoulder strap on your shoulder, and then hold it on the outside of the rubber sleeve on the outside of the grip. S2. Pull the spring pin so that the movable end of the spring pin is pulled out of the insertion hole of the lever. At this time, the push spring outside the guide post releases its elastic force, pushing the connecting sleeve so that the connecting sleeve is fitted onto the outside of the connector to complete the docking. Then, the drive motor drives the drive rod to rotate, and through the engagement of the drive gear and the driven gear, the rotating shaft drives the guide post to rotate, which in turn causes the threaded sleeve to rotate, causing the screw to move along the axial direction of the threaded sleeve. Through the fixed block, the outer sliding sleeve is pushed out. Then, the rotation direction of the drive motor is changed by the reversing switch outside the operation control unit, causing the outer sliding sleeve to retract. When adjusted to a suitable length, the lever is moved, and then the movable end of the spring pin is inserted into the insertion hole of the lever to complete the positioning. S3. Align the picking head with the branch where the target fruit is located, use the V-hook to hook the branch, or let the top rod hold the branch. Then, pull the control trigger on the control unit with your index finger to start the drive motor in the motor mounting unit. The output end of the drive motor drives the drive rod to rotate. Since the drive rod is prismatic and is movably sleeved in the inner sliding sleeve, it drives the inner sliding sleeve to rotate synchronously. When the inner sliding sleeve rotates, the rotating disk at its end rotates as well, causing the guide wheel to roll in the guide groove of the swing head, forcing the swing head to swing back and forth in the swing seat, driving the picking head to vibrate at a certain frequency. By hooking the branch with the V-hook or holding the branch with the top rod, the mature fruit falls off the branch.

[0017] S4. After the fruit on a single branch has been picked, release the control trigger to stop the drive motor, move the equipment to the next target branch, and repeat the above steps for continuous picking.

[0018] The present invention has the following beneficial effects: 1. This invention aligns the picking head with the branch where the fruit is located, then hooks the branch with a V-shaped hook or pushes it with a rod. Subsequently, the control trigger is pulled to start the drive motor. The drive rod drives the inner sliding sleeve to rotate, causing the guide wheel on the rotating disk to roll in the guide groove of the swing head, forcing the swing head to swing back and forth, causing the picking head to vibrate, so that the mature fruit falls, thereby improving the picking efficiency.

[0019] 2. This invention uses a spring pin to disengage it from the lever insertion port. At this time, the spring is pushed to release its elasticity and push the connecting sleeve to fit the connector head and complete the connection. Then, the drive motor drives the drive rod to rotate, which in turn drives the guide column to rotate through gear transmission. This causes the threaded sleeve to rotate and the screw to move. The outer sliding sleeve is pushed out through the fixing block. After that, the reversing switch is operated to change the direction of the motor, which can retract the outer sliding sleeve. This adapts to fruit picking at different heights and positions, thus improving the applicability of the device. Attached Figure Description

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

[0028] Example 1 Please see Figures 1 to 4 The present invention is a portable fruit picking machine, including a shell 100. The shell 100 includes a control unit 101, an upper mounting part 102, a lower mounting part 103, a motor mounting part 104, and a grip part 105. The upper mounting part 102 and the lower mounting part 103 are arranged in parallel to each other, and both the upper mounting part 102 and the lower mounting part 103 are connected to the front end of the control unit 101. The grip part 105 is located between the control unit 101 and the motor mounting part 104. The vibration assembly 200 includes a drive motor 201 fixedly connected to the motor mounting portion 104, an outer sliding sleeve 203 movably sleeved in the upper mounting portion 102, and a prism-shaped drive rod 202 rotatably connected inside the control portion 101. One end of the drive rod 202 is fixedly connected to the output end of the drive motor 201. An inner sliding sleeve 204 is rotatably connected inside the outer sliding sleeve 203, and the other end of the drive rod 202 is movably sleeved inside the inner sliding sleeve 204. The outer sliding sleeve 203 is positioned away from the drive motor 201. A swing seat 206 is fixedly connected to the end of the swing seat 206, and a swing head 208 is rotatably connected inside the swing seat 206. A picking head 210 is fixedly connected to the end of the swing head 208 that is away from the drive motor 201. The prismatic drive rod 202 can stably transmit the power of the drive motor 201 and avoid slippage during transmission. The rotatable connection between the outer sliding sleeve 203 and the inner sliding sleeve 204, together with the rotatable connection between the swing seat 206 and the swing head 208, can convert the rotational motion of the drive motor 201 into the swinging motion of the picking head 210, thereby realizing the fruit picking function.

[0029] Specifically, the other end of the swing head 208 is provided with a guide groove 209. The end of the inner sliding sleeve 204 opposite to the drive motor 201 is fixedly connected to a rotating disk 205. The side of the rotating disk 205 opposite to the inner sliding sleeve 204 is rotatably connected to a guide wheel 207 that rolls in the guide groove 209. The guide wheel 207 rolls in the guide groove 209, which can smoothly convert the rotational motion of the rotating disk 205 into the reciprocating swing motion of the swing head 208, reduce friction and resistance during the movement, improve energy transfer efficiency, and ensure the stability and reliability of the picking head 210's movement.

[0030] Furthermore, it also includes a power supply assembly 500, which includes a battery pack 501 for powering the entire device. A ventilator 502 is fixedly connected to the back of the battery pack 501, and a foam pad 503 is fixedly connected to the side of the ventilator 502 facing away from the battery pack 501. The battery pack 501 provides an independent power source for the device, eliminating the constraints of cables, improving portability, and extending battery life. The ventilator 502 and the foam pad 503 can improve comfort during use and reduce the pressure on the operator. The picking head 210 includes a fixed base 210a fixedly connected to one end of the swing head 208 away from the drive motor 201. Two symmetrically distributed V-shaped hooks 210b and a top rod 210c located between the two V-shaped hooks 210b are fixedly connected to the side of the fixed base 210a away from the swing head 208. The swing head 208 and the outer sliding sleeve 203 are fixedly sleeved with a protective sleeve 600, and the swing seat 206 is located inside the protective sleeve 600. The protective sleeve 600 can effectively protect the moving parts such as the swing head 208, the outer sliding sleeve 203 and the swing seat 206, and prevent external debris from being drawn in and affecting the operation of the equipment.

[0031] The operation process of this embodiment is as follows: When it is necessary to pick fruit, first align the picking head 210 with the branch where the target fruit is located, use the V-shaped hook 210b to hook the branch, or let the top rod 210c hold the branch, and then pull the control trigger 400 on the control unit 101 with the index finger to start the drive motor 201 in the motor mounting unit 104. The output end of the drive motor 201 drives the drive rod 202 to rotate. Since the drive rod 202 is prismatic and is movably sleeved in the inner sliding sleeve 204, it drives the inner sliding sleeve 204 to rotate synchronously. When the inner sliding sleeve 204 rotates, the rotating disk 205 at its end rotates accordingly, causing the guide wheel 207 to roll in the guide groove 209 of the swing head 208, forcing the swing head 208 to swing back and forth in the swing seat 206, driving the picking head 210 to vibrate at a certain frequency. By using the V-shaped hook 210b to hook the branch and vibrate, or the top rod 210c to hold the branch and vibrate, the mature fruit can fall from the branch, improving the picking efficiency.

[0032] Example 2 Please see Figures 1 to 3 Based on the first specific embodiment, the telescopic component 300 includes a threaded sleeve 301 rotatably connected to the inside of the lower mounting part 103. A screw 302 is threaded inside the threaded sleeve 301. A fixing block 203a is fixedly connected to the outside of the outer sliding sleeve 203, and the free end of the screw 302 is fixedly connected to the outside of the fixing block 203a. The threaded engagement between the threaded sleeve 301 and the screw 302 enables the telescopic adjustment of the outer sliding sleeve 203, changing the extension length of the picking head 210, so that the device can adapt to fruit picking at different heights and positions, thus improving the applicability of the device. The control unit 101 is internally connected to a rotating shaft 303, and externally connected to a driven gear 304. Externally connected to the drive rod 202 is a driving gear 305 that meshes with the driven gear 304. A prism-shaped guide post 306 is fixedly connected to the end of the rotating shaft 303 facing away from the drive motor 201. A connecting sleeve 307 is movably sleeved on the outside of the guide post 306. A connector 308 that matches the connecting sleeve 307 is fixedly connected to the end of the threaded sleeve 301 facing the drive motor 201. The driving gear 305 and the driven gear 304 mesh and transmit power, realizing the power transmission between the drive rod 202 and the rotating shaft 303. The telescopic component 300 can be driven without an additional power source, simplifying the equipment structure. The cooperation between the prism-shaped guide post 306 and the connecting sleeve 307 ensures the stability and accuracy of power transmission, making the rotation of the threaded sleeve 301 smoother.

[0033] Specifically, a lever 309 is fixedly connected to the outside of the connecting sleeve 307. An insertion port 310 is provided inside the lever 309. A guide frame 101a, communicating with the control unit 101, is fixedly connected to the bottom of the control unit 101. The lever 309 is slidably connected inside the guide frame 101a. A wedge-shaped spring pin 311 is fixedly connected to the outside of the guide frame 101a, and the movable end of the spring pin 311 is inserted into the insertion port 310. A push spring 312 is movably sleeved on the outside of the guide post 306, and the push spring 312 is located between the connecting sleeve 307 and the rotating shaft 303. The lever 309 allows the operator to manually control the connection and separation of the connecting sleeve 307 and the connector 308, enabling flexible switching of the telescopic function. The spring pin 311, in cooperation with the insertion port 310, can lock the position of the lever 309 to prevent misoperation. The push spring 312 provides a restoring force to ensure reliable cooperation between the connecting sleeve 307 and the connector 308.

[0034] Furthermore, a control trigger 400 for controlling the speed of the drive motor 201 is installed at the end of the control unit 101 facing the drive motor 201. A reversing switch 900 for controlling the rotation direction of the drive motor 201 is installed on the outside of the control unit 101. The control trigger 400 can adjust the speed of the drive motor 201 in real time, control the swing amplitude and frequency of the picking head 210, and adapt to the picking needs of different fruits. The reversing switch 900 can change the rotation direction of the drive motor 201, and the length of the device can be flexibly adjusted. The control unit 101 is externally fixedly connected to a shoulder strap 700, and the grip unit 105 is externally fixedly fitted with a rubber sleeve 800. The shoulder strap 700 makes it convenient for operators to carry the equipment and reduces the burden on their hands. The rubber sleeve 800 of the grip unit 105 can increase the friction of the hand, prevent the equipment from slipping, and improve the comfort of holding.

[0035] The operation process of this embodiment is as follows: When the length of the device needs to be adjusted, the spring pin 311 is pulled, so that the movable end of the spring pin 311 is pulled out from the insertion port 310 of the lever 309. At this time, the push spring 312 outside the guide post 306 releases its elastic force, pushing the connecting sleeve 307 so that the connecting sleeve 307 is fitted onto the outside of the connector 308 to complete the docking. Then, the drive motor 201 drives the drive rod 202 to rotate. Through the engagement of the drive gear 305 with the driven gear 304, the rotating shaft 303 drives the guide post 306 to rotate, thereby causing the threaded sleeve 301 to rotate. This causes the screw 302 to move axially along the threaded sleeve 301. The fixing block 203a pushes the outer sliding sleeve 203 to extend. Then, the reversing switch 900 outside the operation control unit 101 changes the rotation direction of the drive motor 201, causing the outer sliding sleeve 203 to retract. This allows the device to adapt to fruit picking at different heights and positions, improving the applicability of the device.

[0036] Example 3 This embodiment is the third embodiment of the present invention. This embodiment provides a method for using a portable fruit harvester to harvest fruit according to the following steps: S1. Wear the battery pack 501 on your back, then put the shoulder strap 700 on your shoulder, and then hold it on the outside of the rubber sleeve 800 outside the grip part 105. S2. Pull the spring pin 311 so that the movable end of the spring pin 311 is pulled out of the insertion port 310 of the lever 309. At this time, the push spring 312 outside the guide post 306 releases its elastic force and pushes the connecting sleeve 307 so that the connecting sleeve 307 is fitted onto the outside of the connector 308 to complete the docking. Then, the drive motor 201 drives the drive rod 202 to rotate. Through the engagement of the drive gear 305 with the driven gear 304, the rotating shaft 303 drives the guide post 306 to rotate, thereby causing the threaded sleeve 301 to rotate. This causes the screw 302 to move axially along the threaded sleeve 301. The fixing block 203a pushes the outer sliding sleeve 203 to extend. Then, the rotation direction of the drive motor 201 is changed by the reversing switch 900 outside the operation control unit 101, causing the outer sliding sleeve 203 to retract. When the length is adjusted to a suitable length, the lever 309 is moved. Then, the movable end of the spring pin 311 is inserted into the insertion port 310 of the lever 309 to complete the positioning. S3. Align the picking head 210 with the branch where the target fruit is located, use the V-hook 210b to hook the branch, or let the top rod 210c hold the branch, and then pull the control trigger 400 on the control unit 101 with your index finger to start the drive motor 201 in the motor mounting unit 104. The output end of the drive motor 201 drives the drive rod 202 to rotate. Since the drive rod 202 is prismatic and is movably sleeved in the inner sliding sleeve 204, it drives the inner sliding sleeve 204 to rotate synchronously. When the inner sliding sleeve 204 rotates, the rotating disk 205 at its end rotates accordingly, causing the guide wheel 207 to roll in the guide groove 209 of the swing head 208, forcing the swing head 208 to swing back and forth in the swing seat 206, driving the picking head 210 to vibrate at a certain frequency. By hooking the branch with the V-hook 210b or holding the branch with the top rod 210c, the mature fruit falls from the branch.

[0037] S4. After the fruit on a single branch has been picked, release the control trigger 400 to stop the drive motor 201, move the equipment to the next target branch, and repeat the above steps for continuous picking.

9. A portable fruit harvester according to claim 1, characterized in that, The control unit (101) is externally fixedly connected to a shoulder strap (700), and the grip unit (105) is externally fixedly fitted with a rubber sleeve (800).

10. A method of using a portable fruit harvester, characterized in that: A portable fruit harvester according to any one of claims 1 to 9 harvests fruit according to the following steps: S1. Carry the battery pack (501) on your back, then put the shoulder strap (700) on your shoulder, and then hold it on the outside of the rubber sleeve (800) outside the grip (105); S2. Pull the spring pin (311) to pull the movable end of the spring pin (311) out of the socket (310) of the lever (309). At this time, the push spring (312) outside the guide post (306) releases its elastic force and pushes the connecting sleeve (307) so that the connecting sleeve (307) is fitted onto the outside of the connector (308) to complete the docking. Then, the drive motor (201) drives the drive rod (202) to rotate, and the drive gear (305) meshes with the driven gear (304) to make the rotating shaft (303) drive the guide post (306). Rotation causes the threaded sleeve (301) to rotate, causing the screw (302) to move axially along the threaded sleeve (301). The outer sliding sleeve (203) is pushed out by the fixing block (203a). Then, the rotation direction of the drive motor (201) is changed by the reversing switch (900) outside the operation control unit (101), causing the outer sliding sleeve (203) to retract. When adjusted to a suitable length, the lever (309) is moved, and then the movable end of the spring pin (311) is inserted into the socket (310) of the lever (309) to complete the positioning. S3. Align the picking head (210) with the branch where the target fruit is located, hook the branch with the V-hook (210b), or let the top rod (210c) hold the branch, and then pull the control trigger (400) on the control unit (101) with your index finger to start the drive motor (201) in the motor mounting unit (104). The output end of the drive motor (201) drives the drive rod (202) to rotate. Since the drive rod (202) is prismatic and is movably sleeved in the inner sliding sleeve (204), it further drives the fruit to rotate. The inner sliding sleeve (204) rotates synchronously. When the inner sliding sleeve (204) rotates, the rotating disk (205) at its end rotates accordingly, causing the guide wheel (207) to roll in the guide groove (209) of the swing head (208), forcing the swing head (208) to swing back and forth in the swing seat (206), driving the picking head (210) to vibrate at a certain frequency. The V-shaped hook (210b) hooks the branch to vibrate or the top rod (210c) pushes the branch to vibrate, causing the mature fruit to fall from the branch. S4. After the fruit on a single branch is picked, release the control trigger (400) to stop the drive motor (201), move the equipment to the next target branch, and repeat the above steps to pick continuously.
