[0051] Embodiment 1

[0052] like Figure 1-Figure 7 As shown, the embodiment of the present application provides an automatic pruning device for a citrus orchard, which includes a handle 100, a pruning blade 200 and a drive cylinder 300. The handle 100 is designed as a cylindrical structure for easy handholding. A connecting portion 110 is installed at the end of the handle 100 for installing the pruning blade 200. A pin 210 and a transmission arm 220 are fixed to the end of the pruning blade 200. The pruning blade 200 is hinged to the connecting portion 110 through the pin 210, and the blade side of the pruning blade 200 faces the connecting portion 110. A transmission shaft 221 is fixed to the transmission arm 220. The drive cylinder 300 is installed in the handle 100. The drive cylinder 300 is preferably an electric cylinder. The output shaft of the drive cylinder 300 extends to the upper side of the handle 100 and is fixed to a drive frame 310. The drive frame 310 is provided with a drive hole 311 of a waist-shaped structure, and the drive shaft 221 is movably installed in the drive hole 311.

[0053] By adopting the above technical solution, when it is necessary to cut citrus branches, the operator can hold the handle 100, then place the branch between the connection part 110 and the pruning blade 200, and then control the output shaft of the drive cylinder 300 to extend, and drive the pruning blade 200 to rotate toward the side close to the connection part 110 through the drive frame 310, the transmission arm 220 and other structures, so as to perform the pruning operation. The device uses the drive cylinder 300 as the driving source, which can ensure the output of greater power and can smoothly cut harder branches; and the device uses the drive frame 310, the transmission arm 220 and other structures as the transmission structure to drive the pruning blade 200 to rotate. Compared with the gear transmission structure, this method is less subject to wear, ensuring that the device can work for a long time and can also extend the service life.

[0054] In this embodiment, a hidden groove 111 is provided on one side of the connection portion 110 facing the pruning blade 200, and the pruning blade 200 can enter the hidden groove 111. By setting it in this way, when the device is not in use, the pruning blade 200 can be controlled to enter the hidden groove 111, so as to prevent the pruning blade 200 from being exposed and accidentally injuring the operator.

[0055] Since some citrus trees may have some germs, the pruning blade 200 may also be infected with germs when pruning such branches. If the next branch is cut, the germs may be transmitted to other fruit trees. In order to reduce the risk of germ transmission caused by pruning operations, in this embodiment, the automatic pruning device also includes a disinfection mechanism for disinfecting the pruning blade 200.

[0056] The disinfection mechanism includes two liquid spraying pipes 400, a liquid storage bottle 500 and a liquid supply assembly. Among them, the two liquid spraying pipes 400 are symmetrically installed on both sides of the hidden groove 111, and the two sides of the hidden groove 111 are respectively provided with installation grooves for installing the liquid spraying pipes 400. A plurality of uniformly arranged liquid spraying heads 410 are installed on the liquid spraying pipes 400, and the liquid spraying direction of the liquid spraying heads 410 is toward the pruning blade 200 entering the hidden groove 111. In addition, the liquid spraying pipe 400 is designed as an arc structure, which can be adapted to the structure of the pruning blade 200, and the installation position of the liquid spraying pipe 400 is close to the open side of the hidden groove 111, so that the pruning blade 200 can receive the disinfectant from the beginning of entering the hidden groove 111. The liquid storage bottle 500 is detachably installed on the handle 100, and the liquid storage bottle 500 is used to store the disinfectant, and the disinfectant can be alcohol. The liquid supply assembly is used to transport the disinfectant in the liquid storage bottle 500 to the liquid spraying pipe 400.

[0057] By adopting the above-mentioned technical scheme, after the pruning blade 200 has cut the branch, it can enter the hidden groove 111. In the process of the pruning blade 200 entering the hidden groove 111, the disinfectant in the liquid storage bottle 500 can be transported to the spray pipe 400 through the liquid supply component, and then sprayed to both sides of the pruning blade 200 through the spray heads 410 on both sides, thereby disinfecting and sterilizing both sides of the pruning blade 200. When the sterilized pruning blade 200 acts on the next branch, it can reduce the risk of pathogen infection caused by the pruning operation, thereby ensuring the healthy growth of citrus trees.

[0058] In this embodiment, the liquid supply assembly includes a liquid supply pipe 610, a piston plate 620, a push plate 630 and a transmission rod 640. The liquid supply pipe 610 is fixed on the connecting portion 110, and a first one-way valve 611 and a second one-way valve 612 connected to the liquid supply pipe 610 are installed on the liquid supply pipe 610. The first one-way valve 611 is connected to the two liquid spraying pipes 400 through a hose, and the second one-way valve 612 is connected to the liquid storage bottle 500 through a hose. The first one-way valve 611 and the second one-way valve 612 are both one-way ball valves. Through the first one-way valve 611, the disinfectant can only flow from the liquid supply pipe 610 to the liquid spraying pipe 400, and through the second one-way valve 612, the disinfectant can only flow from the liquid storage bottle 500 to the liquid supply pipe 610. The piston plate 620 is installed in the liquid supply pipe 610 to slide along the axial direction of the liquid supply pipe 610. A piston rod 621 is fixed on the piston plate 620, and the end of the piston rod 621 extends to the outside of the liquid supply pipe 610. The push plate 630 is fixed on the end of the piston rod 621 away from the piston plate 620. A spring 650 is installed between the push plate 630 and the liquid supply pipe 610, and the spring 650 is sleeved on the piston rod 621. One end of the transmission rod 640 is fixed on the pin 210, and the other end is installed with a transmission ball 641. The push plate 630 is located on the movement track of the transmission ball 641. When the transmission ball 641 contacts the push plate 630, the transmission ball 641 can drive the push plate 630 to move in the direction of the compression spring 650.

[0059] By adopting the above-mentioned technical solution, when the pruning blade 200 enters the hidden groove 111, the pin shaft 210 of the pruning blade 200 can drive the transmission rod 640 to rotate clockwise. When the transmission ball 641 on the transmission rod 640 contacts the push plate 630, the transmission ball 641 can drive the push plate 630 to move in the direction of the compression spring 650, thereby driving the piston plate 620 to move to the side away from the push plate 630 through the piston rod 621, thereby transmitting the disinfectant in the liquid supply pipe 610 to the two spray pipes 400, and finally spraying it to the two sides of the pruning blade 200 through the spray head 410 to disinfect the pruning blade 200. After the pruning blade 200 moves out of the hidden groove 111, the pin 210 of the pruning blade 200 can drive the transmission rod 640 to rotate counterclockwise, so that the transmission ball 641 is disengaged from the push plate 630, and the push plate 630, under the rebound action of the spring 650, drives the piston plate 620 to move closer to the push plate 630 through the piston rod 621, thereby sucking the disinfectant in the liquid storage bottle 500 into the liquid supply pipe 610, preparing for the next spraying of the disinfectant.

[0060] In this embodiment, two cleaning plates 120 are installed on the connecting portion 110, and the two cleaning plates 120 are symmetrically installed on both sides of the hidden groove 111. Cleaning cotton 121 is arranged on the cleaning plate 120, and part of the structure of the cleaning cotton 121 extends into the hidden groove 111, and the liquid spraying pipe 400 and the cleaning cotton 121 are arranged in sequence from the open end to the inside of the hidden groove 111, that is, the position of the liquid spraying pipe 400 is set close to the open side of the hidden groove 111, and the position of the cleaning cotton 121 is set away from the open side of the hidden groove 111. Through such a setting, the pruning blade 200 after disinfection will continue to move to the position of the cleaning cotton 121, and the two sides of the pruning blade 200 will be wiped by the cleaning cotton 121 on both sides. On the one hand, it can wipe the stains on the surface of the pruning blade 200, and on the other hand, it can wipe the excess disinfectant on the surface of the pruning blade 200, thereby improving the cleanliness of the pruning blade 200.

[0061] In this embodiment, a connecting plate 122 is provided on the cleaning plate 120, and bolts 123 are installed on the connecting plate 122, and the connecting plate 122 is detachably mounted on the connecting portion 110 through the bolts 123. By such a configuration, after the device is used for a period of time, the cleaning plate 120 can be disassembled and replaced with a new cleaning cotton 121, which is convenient for replacement.

[0062] In this embodiment, a connecting ring 510 is provided at the end of the liquid storage bottle 500, and a connecting surface 130 adapted to the connecting ring 510 is provided at one end of the handle 100 away from the connecting portion 110, and the connecting ring 510 is threadedly connected to the connecting surface 130. Specifically, an internal thread is provided on the connecting ring 510, and an external thread is provided on the connecting surface 130, and the connecting surface 130 and the connecting ring 510 are threadedly connected through the external thread and the internal thread. Through such a configuration, on the one hand, the liquid storage bottle 500 and the handle 100 can be connected as one body, so that the liquid storage bottle 500 can also be used as a part of the handle 100, and on the other hand, it is also convenient to disassemble the liquid storage bottle 500.

[0063] In this embodiment, anti-skid patterns 140 are provided on the outer side walls of the handle 100 and the liquid storage bottle 500. The anti-skid patterns 140 are provided to facilitate the operator to hold the device for pruning.

[0064] In this embodiment, an extension rod (not shown) is detachably mounted on the handle 100, through which the handle 100 can be extended. By such a configuration, when encountering a branch at a higher position, the extension rod can be mounted on the handle 100, so that the device can smoothly cut the branch at a higher position.
