Description

Technical Field

[0001] This utility model relates to the field of apple picking technology, specifically to an apple picking machine that prevents bumps and knocks. Background Technology

[0002] In the process of modern agricultural development, apples, as a widely cultivated fruit with extremely high economic value, play a crucial role in the efficiency and quality of their harvesting process. With the increasing trend of large-scale and intensive orchard management, the limitations of traditional manual harvesting methods are becoming more and more apparent, making the application of harvesting machines an inevitable choice.

[0003] However, existing apple harvesters designed to prevent bruising still have some drawbacks in practical use: They generally lack the ability to accurately sense and adaptively adjust to individual apple differences. When harvesting larger apples or those with thinner skins, if the harvester uses a fixed clamping force, it is very easy for the skin to break and the flesh to be crushed due to excessive clamping. This damage not only affects the appearance of the apples but also makes them more susceptible to microbial contamination during subsequent storage and transportation, significantly shortening their shelf life and reducing their commercial value. Conversely, when harvesting smaller apples or those with tough stems, insufficient clamping force can result in the apples falling during harvesting, causing fruit damage or even complete spoilage, increasing production costs.

[0004] To address this issue, we designed an apple-picking machine that prevents bumps and knocks. Utility Model Content

[0005] The purpose of this invention is to provide an apple picking machine that prevents bumps and knocks, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an apple picking machine to prevent bumps and knocks, including a base, with drive rods rotatably connected to both sides of the top of the base, a connecting rod hinged to the end of the drive rod away from the base, and a clamping plate fixedly connected to the other end of the connecting rod. A buffer plate is provided on the opposite side of the clamping plate, and a plurality of buffer springs are fixedly connected between the clamping plate and the buffer plate.

[0007] Furthermore, a button is installed at the center of the side of the clamping plate near the buffer plate, and a contact block is installed on the side of the buffer plate near the clamping plate, the contact block and the button being compatible.

[0008] Furthermore, a first gear is rotatably connected to one side of the base, and the top of the first gear is fixedly connected to one of the drive rods. A second gear is rotatably connected to the other side of the base, and the top of the second gear is fixedly connected to another drive rod.

[0009] Furthermore, the first gear and the second gear mesh on one side, the bottom end of the first gear is meshed with a drive gear, and the middle part of the drive gear is connected to a motor.

[0010] Furthermore, the motor is fixedly connected to the outer wall of the base, and the motor is electrically connected to the button.

[0011] Furthermore, a limiting hole is provided at the top of the base, and a limiting rod is rotatably connected in the limiting hole. The limiting rod is rotatably connected to the bottom of the clamping plate.

[0012] Furthermore, mounting plates are fixedly connected to both sides of the top of the base, and threaded holes are provided on the mounting plates.

[0013] Furthermore, the buffer plate is made of rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a buffer plate is provided on the opposite side of the clamping plate of the harvester, and multiple buffer springs are fixedly connected between the two. The buffer plate is made of rubber. During harvesting, the buffer plate contacts the apple first. The good elasticity of the rubber and the buffer springs work together to effectively absorb and disperse the impact force during clamping, avoiding direct hard collision between the apple and the clamping plate. This greatly reduces the probability of damage to the apple during the harvesting process, ensures the appearance and quality of the apple, and improves its commercial value.

[0016] 2. In this invention, the contact block on the buffer plate is compatible with the button on the clamping plate, and the button is electrically connected to the motor. When the buffer plate contacts the apple and moves towards the clamping plate, the contact block triggers the button, and the motor stops working. This ensures that the clamping plate applies moderate clamping force to the apple, guaranteeing a stable grip on the apple without damaging it due to excessive force. This achieves precise control of the harvesting action, improving the success rate and reliability of harvesting. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an apple picking machine to prevent bumps and knocks, including a base 1, with drive rods 2 rotatably connected to both sides of the top of the base 1, a connecting rod 3 hinged to the end of the drive rod 2 away from the base 1, and a clamping plate 4 fixedly connected to the other end of the connecting rod 3, with buffer plates 5 provided on opposite sides of the clamping plate 4, and multiple buffer springs 6 fixedly connected between the clamping plate 4 and the buffer plate 5, with a button 7 installed at the center of the side of the clamping plate 4 near the buffer plate 5, and a contact block 8 installed on the side of the buffer plate 5 near the clamping plate 4, the contact block 8 and the button 7 being compatible.

[0024] In practice, when the drive rod 2 rotates, it drives the clamping plate 4 to move via the connecting rod 3. When the two drive rods 2 rotate outward, the clamping plates 4 move away from each other; when the two drive rods 2 rotate inward, the clamping plates 4 move closer to each other, thus achieving the release and clamping action on the apple. During the process of the clamping plate 4 approaching the apple, if the buffer plate 5 contacts the apple first, the buffer plate 5 will be squeezed and move towards the clamping plate 4, compressing the buffer spring 6, which plays a buffering role and prevents the clamping plate 4 from directly colliding with the apple and causing damage. At the same time, the contact block 8 on the buffer plate 5 will gradually approach the button 7 on the clamping plate 4. When the two make contact, the button 7 is triggered, and the motor 12 stops working. At this time, the clamping force of the clamping plate 4 on the apple is moderate, which can firmly grasp the apple without damaging it due to excessive force.

[0025] See Figure 3A first gear 9 is rotatably connected to one side of the base 1. The top of the first gear 9 is fixedly connected to one of the drive rods 2. A second gear 10 is rotatably connected to the other side of the base 1. The top of the second gear 10 is fixedly connected to another drive rod 2. The first gear 9 and the second gear 10 mesh on one side. A drive gear 11 is meshed to the bottom of the first gear 9. A motor 12 is connected to the middle part of the drive gear 11. The motor 12 is fixedly connected to the outer wall of the base 1. The motor 12 is electrically connected to the button 7.

[0026] In practice, the motor 12 drives the drive gear 11 to rotate, the first gear 9 rotates accordingly, and the second gear 10 also rotates. The first gear 9 and the second gear 10 are respectively fixedly connected to the two drive rods 2, so that the two drive rods 2 will rotate around the connection points on both sides of the top of the base 1 under the drive of the gears.

[0027] See Figure 4 A limiting hole 14 is provided on the top of the base 1, and a limiting rod 13 is rotatably connected in the limiting hole 14. The limiting rod 13 is rotatably connected to the bottom of the clamping plate 4.

[0028] In practice, when the clamping plate 4 moves with the drive rod 2 and the connecting rod 3, the limiting rod 13 rotates within the limiting hole 14, which restricts the range of motion of the clamping plate 4, so that it can only move on a specific trajectory, preventing the clamping plate 4 from shaking or shifting during the picking process, and ensuring the accuracy and stability of the picking action.

[0029] See Figure 4 Mounting plates 15 are fixedly connected to both sides of the top of the base 1, and threaded holes are provided on the mounting plates 15.

[0030] In practice, mounting plates 15 are fixedly connected to both sides of the top of the base 1. The threaded holes on these plates can be used to install the harvester on other equipment or support structures. By using bolts or other connectors passing through the threaded holes, the harvester is firmly fixed to ensure that it will not shift during operation and that the harvesting operation can proceed smoothly.

[0031] See Figure 2 The buffer plate 5 is made of rubber.

[0032] In practice, the rubber is soft and can conform to the irregular surface of the apple to a certain extent. When picking apples of different shapes and sizes, the buffer plate 5 can better adapt to the contour of the apple. It can not only distribute the clamping force more evenly and avoid excessive local force, but also increase the friction with the apple to a certain extent, making the apple less likely to slip during the picking process.

[0033] Working principle:

[0034] Pressing the start button 7 of the harvester powers on the motor 12, which in turn drives the drive gear 11 to rotate. Since the drive gear 11 meshes with the first gear 9, the first gear 9 rotates accordingly. Furthermore, because the first gear 9 meshes with the second gear 10, the second gear 10 also rotates. The first gear 9 and the second gear 10 are fixedly connected to two drive rods 2, so that the two drive rods 2 rotate around the connection points on both sides of the top of the base 1 under the drive of the gears.

[0035] When the drive rod 2 rotates, it drives the clamping plate 4 to move via the connecting rod 3. When the two drive rods 2 rotate outward, the clamping plates 4 move away from each other; when the two drive rods 2 rotate inward, the clamping plates 4 move closer to each other, realizing the release and clamping action of the apple. During the process of the clamping plate 4 approaching the apple, if the buffer plate 5 contacts the apple first, the buffer plate 5 will be squeezed and move towards the clamping plate 4, compressing the buffer spring 6, which plays a buffering role and avoids the clamping plate 4 directly colliding with the apple and causing damage. At the same time, the contact block 8 on the buffer plate 5 will gradually approach the button 7 on the clamping plate 4. When the two make contact, the button 7 is triggered, the motor 12 stops working, and at this time the clamping force of the clamping plate 4 on the apple is moderate, which can firmly grasp the apple without damaging it due to excessive force.
