Description

Technical Field

[0001] The invention belongs to the technical field of fruit tree picking, and in particular relates to a high-altitude picking device for tall fruit trees. Background Art

[0002] Fruit trees refer to trees with edible fruits, and are a general term for perennial plants and their rootstocks that can provide edible fruits and seeds. Fruit tree planting is an effective way for us to develop the agricultural economy. Planting a large number of fruit trees ensures that we can have a variety of fruits. Fruit tree picking devices are devices that ensure that the ripe fruits can be picked in a timely and effective manner.

[0003] According to the publication number CN218483269U, the name is a high-altitude picking device for fruit trees, including a fruit collecting bin, a mounting plate is detachably installed on one side of the fruit collecting bin, and disassembly bolts are provided at the four corners of the mounting plate, and the other end of the disassembly bolt is inserted into one end of the fruit collecting bin, a fruit entry hole is opened on one side of the inner center of the mounting plate, a buffer net is provided on one side of the inner center of the collecting bin, a picking component is provided in the fruit entry hole, and a handle is fixedly installed on one end of the upper surface of the fruit collecting bin. The utility model has the advantages of disassembly bolts detachably installed at the four corners of the mounting plate, which makes it convenient for staff to disassemble and take out the collected fruits, reduce falling, and facilitate picking of fruits through the picking component provided in the fruit entry hole, which can effectively reduce the occurrence of fruits falling on the ground and breaking, reduce damage, improve picking quality, and facilitate later sale.

[0004] However, in the actual picking process, especially when picking some special fruits, the device exposed some shortcomings. Take mango as an example. The mango stalk is usually thick and tough. When the fruit enters the anti-drop ring, the stalk will shake more obviously because the device lacks a structure to fix the stalk. When cutting the stalk, the shaking stalk makes it difficult to accurately determine the cutting position. The cutting part of the picking assembly may not accurately act on the predetermined cutting point of the stalk, resulting in incomplete cutting. In order to pick the fruit completely, the staff may have to perform multiple cutting operations, increasing the risk of damage to the fruit. Summary of the Invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a high-altitude picking device for tall fruit trees.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-altitude picking device for tall fruit trees, comprising a main body, a telescopic cylinder and an electric push rod, and further comprising:

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown, the present invention provides a high-altitude picking device for tall fruit trees, comprising a main body 1, a telescopic cylinder 2 and an electric push rod 3, and further comprising:

[0033] A cutting handle assembly 4 is disposed inside one end of the telescopic cylinder 2;

[0034] A fixing assembly 5, which is arranged on the surface of the telescopic cylinder 2;

[0035] Among them, the fixed component 5 includes a fixed shell 501 fixedly connected to the surface of the telescopic cylinder 2, and the internal rotation connection of the fixed shell 501 is a toothed plate 502, and the surface of the toothed plate 502 is provided with two sliding grooves 503, and the internal sliding connection of the two sliding grooves 503 is two sliding plates 504, one end of the sliding plate 504 extends to the interior of the telescopic cylinder 2, and a clamp 505 is fixedly installed on the side close to the surface of the cutting handle component 4, and a motor 506 is fixedly installed on one side of the outer surface of the fixed shell 501, and a gear 507 is fixedly installed on the output end of the motor 506.

[0036] The above scheme is adopted: the operator places the main body 1 under the tree with the fruit to be picked, and then drives the electric push rod 3 to extend the telescopic cylinder 2, and then wrap the fruit. During the wrapping process, the camera inside the telescopic cylinder 2 will capture the state of the fruit and then display it on the terminal so that the operator can observe the picking status. This is a prior art and will not be described in detail. Then, the motor 506 can be driven to rotate the gear 507, because the gear 507 is engaged with the tooth plate 502, and the rotating gear 507 will drive the tooth plate 502 to rotate. During the rotation of 502, the two sliding plates 504 will slide inside the slide groove 503. During the sliding process, the two clamps 505 will be driven to move toward the fruit stalk, thereby fixing the fruit stalk. After the fixation is completed, the cutting handle component 4 can be driven to cut the fruit stalk, and the cut fruit will enter the interior of the main body 1 along the telescopic cylinder 2. Finally, the clamp 505 will be fixed to the fruit stalk by driving the motor 506, thereby ensuring that the cutting handle component 4 cuts into the fruit stalk at a stable angle, avoiding incomplete cutting or multiple cutting, and improving the success rate of picking.

[0037] like Figure 3 As shown, the cutting handle assembly 4 includes a cylinder 1 401 fixedly connected to the outer surface of the telescopic cylinder 2, and there are two cylinders 1 401. The output ends of the two cylinders 1 401 pass through the telescopic cylinder 2 and are fixedly installed with two cutting handle knives 402.

[0038] Adopting the above scheme: through the design of the cutting handle assembly 4, after the fruit handle is fixed, the cylinder 1 401 can be driven so that its output shaft pushes the two cutting handle knives 402 to move toward the surface of the fruit handle, and the cutting of the fruit handle is completed by extrusion.

[0039] like Figure 4 and Figure 6 As shown, it also includes:

[0040] The adsorption mechanism 6 is arranged inside the telescopic cylinder 2. The adsorption mechanism 6 includes a cylinder 2 601 fixedly connected to the outer surface of the telescopic cylinder 2. The output end of the cylinder 2 601 passes through the telescopic cylinder 2 and is fixedly installed with a suction cup 602. A connecting hose 603 is fixedly installed on the surface of the suction cup 602. A circular cylinder 604 is fixedly installed on one side of the outer surface of the fixed shell 501, and one end of the connecting hose 603 is connected to the circular cylinder 604. A piston block 606 is slidably connected to the inside of the circular cylinder 604. The circular cylinder 604 and the piston block 606 are elastically connected by an elastic member 605. A sliding block 608 is fixedly installed on one end of the sliding plate 504, and the sliding block 608 and the piston block 606 are connected by a connecting rope 607.

[0041] The above scheme is adopted: through the design of the adsorption mechanism 6, when the fruit enters the telescopic cylinder 2, the cylinder 2 601 can be driven so that its output shaft pushes the suction cup 602 to move toward the surface of the fruit, and the surface of the suction cup 602 is brought into contact with the surface of the fruit. Then, when the elastic member 605 moves, it will pull the sliding block 608 to move, and the moving sliding block 608 will pull the connecting rope 607 to move, and the connecting rope 607 will pull the piston block 606 to slide inside the circular cylinder 604. During the movement of the piston block 606, the elastic member 605 will be stretched, and then as the piston block 606 moves, the connecting hose 603 will extract the air inside the suction cup 602, forming a negative pressure space, and then the fruit is adsorbed and fixed. Finally, the piston block 606 is used to extract the air inside the suction cup 602 through the elastic member 605 to fix the fruit, thereby avoiding collision between the fruit and the telescopic cylinder 2 when cutting the fruit, thereby protecting the fruit from damage.

[0042] like Figure 2 As shown, it also includes:

[0043] The buffer assembly 7 is arranged inside the main body 1. The buffer assembly 7 includes an air cushion 701 fixedly connected to the inside of the main body 1. A protective net 702 is fixedly installed inside the main body 1.

[0044] Adopting the above solution: through the design of the buffer component 7, after the fruit enters the main body 1, it will fall on the top of the air cushion 701. Since there is gas inside the air cushion 701, it can buffer the impact force generated by the falling fruit, preventing the fruit from being broken and inedible, and the protective net 702 can prevent the fruit from rolling.

[0045] like Figure 2 As shown, a guide block 8 is fixedly installed on one side of the main body 1 close to the telescopic cylinder 2, and the guide block 8 is designed with an inclined surface.

[0046] Adopting the above solution: through the design of the guide block 8, after the fruit is picked, the telescopic cylinder 2 will guide the fruit to the surface of the guide block 8. Since the guide block 8 is designed as a slope, the fruit will roll along the slope to the top end of the air cushion 701, thereby protecting the fruit from damage to the greatest extent.

[0047] like Figure 4 As shown, one side of the outer surface of the fixed shell 501 is rotatably connected to the guide wheel 9, and the connecting rope 607 is wound around the surface of the guide wheel 9.

[0048] The above solution is adopted: through the design of the guide wheel 9, when the connecting rope 607 moves, the friction between the connecting rope 607 and the guide wheel 9 is utilized, and then the moving connecting rope 607 will drive the guide wheel 9 to rotate, and the rotating guide wheel 9 can guide the connecting rope 607 to move smoothly, thereby improving the service life of the connecting rope 607.

[0049] like Figure 1 and Figure 6 As shown, a ground plug 10 is fixedly installed at the bottom end of the main body 1. There are four ground plugs 10, and the bottom end of the ground plug 10 is conical in design. The piston block 606 is circular in design, and the surface of the piston block 606 is completely in contact with the inner wall of the circular cylinder 604.

[0050] The above-mentioned solution is adopted: through the design of the ground plug 10, after the main body 1 is placed under the tree with the fruit to be picked, the ground plug 10 is inserted into the ground, thereby improving the stability of picking, and the bottom end of the ground plug 10 is conical in design, thereby conveniently inserting the ground plug 10 into the ground, through the design of the piston block 606, since the surface of the piston block 606 is completely in contact with the inner wall of the circular cylinder 604, the sealing of the circular cylinder 604 is ensured, and the gas is prevented from flowing out from the gap between the circular cylinder 604 and the piston block 606 when the piston block 606 moves, thereby improving the stability of the adsorption and fixation of the suction cup 602.

[0051] like Figure 3 and Figure 4 As shown, the slide groove 503 is a curved design, and the sliding plate 504 located inside the slide groove 503 is a circular design. A square hole is opened on one side of the outer surface of the fixed shell 501, and the sliding plate 504 can move inside the square hole. A fixing hole is opened on the surface of the front end clamp 505, and the rear end clamp 505 can move inside the fixing hole.

[0052] The above solution is adopted: through the design of the slide groove 503, since the slide groove 503 is a curved design, the sliding plate 504 will move along the curved direction of the slide groove 503, thereby ensuring that the clamp 505 fixes the fruit stem, and a square hole is opened on one side of the outer surface of the fixed shell 501, thereby not interfering with the movement of the sliding plate 504. Through the design of the clamp 505, according to the drawings in the specification Figure 4 As shown, since a fixing hole is opened on the surface of the front clamp 505, when the two clamps 505 move, the rear clamp 505 will move inside the fixing hole, so that the clamps 505 can fix different fruit stems.

[0053] The working principle and use process of the present invention:

[0054] First, the operator places the main body 1 under the tree with the fruit to be picked, and inserts the ground plug 10 into the ground. Then, the electric push rod 3 can be driven to extend the telescopic cylinder 2 to wrap the fruit. At this time, the driving motor 506 rotates the gear 507, which drives the gear plate 502 to rotate. The sliding plate 504 slides inside the slide groove 503. The sliding plate 504 drives the two clamps 505 to move toward the fruit stalk, thereby fixing the fruit stalk;

[0055] At the same time, the cylinder 2 601 is driven so that its output shaft pushes the suction cup 602 to make it contact with the surface of the fruit, and when the elastic member 605 moves, it will pull the sliding block 608 to move, and the sliding block 608 will pull the connecting rope 607 to move, and the connecting rope 607 will pull the piston block 606 to slide inside the circular cylinder 604. During the movement of the piston block 606, the elastic member 605 will be stretched, and then as the piston block 606 moves, the connecting hose 603 will extract the air inside the suction cup 602, forming a negative pressure space, and then adsorbing and fixing the fruit. After the fixation is completed, the cylinder 1 401 can be driven to cut the fruit stalk, and the cut fruit will enter the interior of the main body 1 along the telescopic cylinder 2, and the guide block 8 will guide the fruit to the top of the air cushion 701, and finally complete the operation process.
