Description

Technical Field

[0001] The invention relates to the technical field of fruit picking, in particular to a fruit picking device and a fruit picking machine. Background Art

[0002] Fruit picking is the most time-consuming and labor-intensive part of agricultural production. It is a labor-intensive job. Fruit picking is usually done manually, and the labor input accounts for about 50% to 70% of the entire planting process. The picking methods in the prior art usually include shaking the tree trunk to make the fruit fall; hitting the branches; or installing pliers on a handheld pole to cut the fruit. Regardless of the picking method, there is a problem of low picking efficiency.

[0003] Especially for tea oil picking, due to the low degree of mechanical automation in the entire tea oil production and processing industry, there is less attention paid to improving the efficiency of tea oil picking. Tea oil planting is discrete planting and manual picking, which hinders the development of the entire industry. Tea oil does not use pesticides or fertilizers during the entire growth process, does not contain erucic acid, cholesterol, aflatoxin and other substances harmful to the human body, has a golden or light yellow color, pure quality and pure taste. Therefore, the country advocates large-scale concentrated planting, but the efficiency of tea oil picking is low, which lengthens the picking cycle and prevents tea oil from being picked in the best condition. Summary of the invention

[0004] To solve the above technical problems, the present invention aims to provide a fruit picking device that can improve the efficiency of fruit picking. Another object of the present invention is to also achieve the above effect.

[0005] The technical solution of the present invention is as follows:

[0007] a transmission mechanism connected to the picking mechanism,

[0008] And a driving telescopic mechanism connected to the transmission mechanism, wherein the driving telescopic mechanism is used to drive the transmission mechanism to move up and down with the picking mechanism.

[0009] Preferably, the drive telescopic mechanism comprises a rotatable crank.

[0010] a first connecting rod connected to the crank,

[0011] and a piston rod connected to the first connecting rod,

[0020] The third connecting rod is connected to the second connecting rod,

[0021] The connection between the third connecting rod and the second connecting rod is hinged to the picking mechanism.

[0022] Preferably, the picking mechanism comprises a beating rod,

[0023] The beating rod is hinged to the connection between the third connecting rod and the second connecting rod.

[0024] At least two toggle rods are arranged on the beating rod.

[0025] Preferably, the toggle rod is made of elastic material.

[0026] Preferably, the length of the toggle rod is less than 30 cm.

[0036] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0037] like Figures 1 to 4 As shown, the fruit picking device provided by the present invention includes a picking mechanism 1 for picking fruits, a transmission mechanism 2 connected to the picking mechanism 1, and a driving telescopic mechanism 3 connected to the transmission mechanism 2. The driving telescopic mechanism 3 is used to drive the transmission mechanism 2 to move up and down with the picking mechanism 1. When it is necessary to pick fruits, the fruit picking device is moved to the top of the fruit tree (target tree), the driving telescopic mechanism 3 starts to work, the driving transmission mechanism 2 moves downward, the picking mechanism 1 contacts the fruit tree, and then the driving transmission mechanism 2 moves upward with the picking mechanism 1. During the up and down movement of the picking mechanism 1, the branches on the fruit tree are driven to vibrate, causing the fruit to fall, and the fruit is picked. The fruit picking device provided by the present application adopts the driving telescopic mechanism 3 to drive the transmission mechanism 2 and the picking mechanism 1 to move up and down, and the friction vibration between the picking mechanism 1 and the fruit tree during the up and down movement is used to make the fruit fall. No human participation is required throughout the process, and the efficiency of fruit picking is greatly improved compared with traditional manual picking.

[0038] like Figure 2As shown, in the embodiment provided by the present invention, the driving telescopic mechanism 3 includes a rotatable crank 31, a first connecting rod 32 connected to the crank 31, and a piston rod 33 connected to the first connecting rod 32, and a sleeve 34 sleeved on the piston rod 33, and the piston rod 33 reciprocates along the inner wall of the sleeve 34. When the driving telescopic mechanism 3 needs to transmit the driving force to the transmission mechanism 2 to pick fruits, the crank 31 rotates, driving the first connecting rod 32 connected to the crank 31 to rotate, the first connecting rod 32 is connected to the piston rod 33, and the piston rod 33 moves along the inner wall of the sleeve 34. When the connection point between the crank 31 and the first connecting rod 32 rotates to the lowest point of the crank 31, the piston rod 33 extends downward, transmits the downward pulling force to the telescopic assembly, and then to the picking assembly, and the picking assembly moves downward; when the connection point between the crank 31 and the first connecting rod 32 rotates to the highest point of the crank 31, the piston rod 33 moves toward the crank 31, transmits the upward pulling force to the telescopic assembly, and then to the picking assembly, and the picking assembly moves upward. During the continuous rotation of the crank 31, the piston rod 33 and the picking assembly are driven to continuously move up and down, so that the picking assembly and the fruit tree generate friction vibration, thereby causing the fruit to fall. Preferably, the connection position of the first connection and the crank 31 is located at the crank 31 away from the center of the crank 31, so that the moving distance of the piston rod 33 is greatly increased, the moving distance of the picking mechanism 1 is expanded, and the picking range of the fruit picking device is expanded.

[0039] In the embodiment provided by the present invention, the transmission mechanism 2 includes a basic component 21, and the basic component 21 includes a first disk 211 connected to the piston rod 33, and the picking mechanism 1 is connected to the first disk 211. The provision of the first disk 211 plays an auxiliary supporting role for the picking mechanism 1. Preferably, at least two or more picking mechanisms 1 are provided along the circumference close to the first disk 211. When the first connecting rod 32 connected to the crank 31 pulls the piston rod 33 to move up and down, the piston rod 33 pulls the first disk 211, and multiple picking mechanisms 1 can be pulled, so that the fruit picking device provided by the present application is more flexible, and the driving telescopic mechanism 3 transmits the driving force to the multiple picking mechanisms 1 through the first disk 211, which greatly improves the picking efficiency.

[0040] The fruit picking device provided by the present invention comprises a basic component 21, a second connecting rod 212 connected to a first plate 211, a second plate 213 arranged below the first plate 211, a support rod 214 connecting the first plate 211 and the second plate 213, and a third connecting rod 215 connected to the second plate 213, wherein the third connecting rod 215 is connected to the second connecting rod 212, and the connection between the third connecting rod 215 and the second connecting rod 212 is hinged to the picking mechanism 1. A support rod 214 is arranged between the first plate 211 and the second plate 213, and when the piston rod 33 pulls the first plate 211 to move upward, the support rod 214 and the second plate 213 are moved upward together, and the picking mechanism 1 is hinged to the connection between the third connecting rod 215 and the second connecting rod 212, and during the upward movement of the first plate 211 and the second plate 213, the picking mechanism 1 rotates around the connection, and the picking mechanism 1 contracts inward. When the second plate 213 moves downward, the picking mechanism 1 rotates around the connection, and the picking mechanism 1 opens outward. This design allows the picking mechanism 1 to move not only up and down but also inward and outward (i.e., left and right). The moving distance of the picking mechanism 1 is increased, and the contact area with the fruit tree is larger, so the picking effect is better and the picking efficiency is higher.

[0041] In the embodiment provided by the present invention, the picking mechanism 1 includes a beating rod 11, which is hinged at the connection between the third connecting rod 215 and the second connecting rod 212, and at least two toggle rods 12 are provided on the beating rod 11. During the picking process, the beating rod 11 approaches the fruit tree, and the two toggle rods 12 on the beating rod 11 are inserted into the fruit tree. During the up and down movement of the picking mechanism 1, the toggle rod 12 rubs against the fruit on the fruit tree, causing the fruit to fall. Preferably, a plurality of toggle rods 12 are provided on the beating rod 11, and the distance between adjacent toggle rods 12 is set according to the size of the fruit. A plurality of toggle rods 12 are provided so that the fruit is in contact with the toggle rod 12 as much as possible. The picking efficiency of the fruit picking device is improved.

[0042] In the embodiment provided by the present invention, the toggle rod 12 is made of elastic material. The toggle rod 12 is set to be an elastic material in order to reduce the damage to the fruit skin caused by the friction between the toggle rod 12 and the fruit. If the fruit picking device is applied to fruit trees that have no requirements on the fruit surface, such as oil tea, the toggle rod 12 can be set to a rigid material to reduce the elastic force loss of the toggle rod 12, and the driving force transmitted by the telescopic device is converted into the friction between the toggle rod 12 and the oil tea fruit, thereby improving the efficiency of fruit picking.

[0043] In the embodiment provided by the present invention, the length of the toggle rod 12 is less than 30 cm. Generally, fruits grow on the outer surface of fruit trees, and the size of fruits is generally less than 30 cm. The length of the toggle rod 12 is set to be less than 30 cm, which reduces the weight of the working parts of the fruit picking device. The driving force output by the telescopic mechanism 3 needs to be subtracted from the gravity of the picking mechanism 1, and the remaining force is converted into the force output by the picking mechanism 1. The length of the toggle rod 12 is set to be less than 30 cm. While ensuring the picking effect and efficiency, the dead weight of the picking mechanism 1 is minimized, the energy efficiency conversion rate of the fruit picking device is improved, and the load borne by the fruit picking device is reduced.

[0044] In the embodiment provided by the present invention, at least one of the second connecting rod 212, the third connecting rod 215 and the beating rod 11 is provided. The second connecting rod is connected to the first disk 211, the third connecting rod is connected to the second disk 213, and the beating rod 11 is hinged at the connection between the second connecting rod 212 and the third connecting rod 215. Preferably, a plurality of second connecting rods 212 are arranged circumferentially close to the first disk 211, and the number of the specific second connecting rods 212 is set according to the size of the fruit tree. Each second connecting rod 212 is correspondingly provided with the same number of third connecting rods 215 and beating rods 11, so that a plurality of beating rods 11 are provided around the outside of the fruit tree, and each beating rod 11 is changed by the working action of the second connecting rod 212 and the third connecting rod 215 to change the position of the beating rod 11, so that the toggle rod 12 on the beating rod 11 contacts the fruit, which greatly improves the picking efficiency.

[0045] The present invention provides a fruit picking machine, including a traveling mechanism, on which a fruit picking device is provided. For example, the fruit picking device can be connected to the end of an excavator boom (forearm) as a tool. The power for driving the telescopic mechanism 3 comes from an excavator hydraulic element or a power supply.

[0046] In order to further explain the working principle of the fruit picking device, the following is described according to the optimal embodiment. The fruit picking device can be used to pick tea fruit. Since the shell of tea fruit needs to be peeled off to obtain tea seeds, the appearance or damage of the shell of tea fruit is not required. Therefore, the fruit picking device provided by the present invention is particularly suitable for fruit trees that do not require the shell of the fruit.

[0047] A fruit picking device is provided at the end of the excavator boom (forearm), and the hydraulic element or power supply of the excavator provides power to the driving telescopic mechanism 3. When the driving telescopic mechanism 3 needs to transmit the driving force to the transmission mechanism 2 to pick fruits, the crank 31 rotates, driving the first connecting rod 32 connected to the crank 31 to rotate as well. The first connecting rod 32 is connected to the piston rod 33, and the piston rod 33 moves along the inner wall of the sleeve 34. When the connection point between the crank 31 and the first connecting rod 32 rotates to the lowest point of the crank 31, the piston rod 33 extends downward, transmits the downward pulling force to the telescopic assembly, and then to the picking assembly, and the picking assembly moves downward; when the connection point between the crank 31 and the first connecting rod 32 rotates to the highest point of the crank 31, the piston rod 33 moves toward the crank 31, transmits the upward pulling force to the telescopic assembly, and then to the picking assembly, and the picking assembly moves upward. The transmission mechanism 2 includes a basic component 21, which includes a second connecting rod 212 connected to the first plate 211, a second plate 213 arranged below the first plate 211, a support rod 214 connecting the first plate 211 and the second plate 213, and a third connecting rod 215 connected to the second plate 213. The third connecting rod 215 is connected to the second connecting rod 212, and the connection between the third connecting rod 215 and the second connecting rod 212 is hinged to the picking mechanism 1. The picking mechanism 1 includes a slapping rod 11, which is hinged to the connection between the slapping rod 11 and the third connecting rod 215 and the second connecting rod 212. At least two toggle rods 12 are arranged on the slapping rod 11, and the toggle rods 12 are made of elastic material, and the length of the toggle rods 12 is less than 30CM.
