[0002] Currently, 5% - 8% of olive oil, 40% - 50% of water remains in the olive pomace, and the rest is mainly lignin and cellulose. The pomace contains fruit stones. In addition to the olive pomace oil which can be used in the soap and daily cosmetics industries, the pomace is also rich in bioactive substances such as olive polyphenols, maslinic acid, and oleanolic acid, which have various pharmacological and physiological activities such as antibacterial and anti-inflammatory effects, blood sugar and lipid lowering effects, anti-HIV effects, anti-tumor effects, and free radical scavenging effects. It is found that maslinic acid can significantly inhibit cell proliferation and cause apoptosis of cancer cells, and maslinic acid has the function of inhibiting the activity of HIV protease. The pomace can also be used as organic fertilizer for forest land covering or for animal feed. The fruit stones can be made into charcoal for barbecue or further activated for the preparation of activated carbon, which is used for decolorization of food and medicine, as well as sewage treatment and other fields; during the process of olive cultivation, the branches of olive trees need to be pruned to meet the growth requirements;

The dust-proof and heat-dissipating cover is provided to dissipate the heat generated by the operation of the reduction motor, and at the same time, the temperature inside the box body is monitored in real time through the provided temperature sensor to prevent the temperature from being too high.

[0014] In a preferred embodiment of the present invention, a semiconductor refrigeration sheet is embedded in the side wall of the box body. The refrigerating surface of the semiconductor refrigeration sheet is arranged inside the box body, and heat dissipation fins are fixed on the outer surface of the box body. The heat dissipation fins are attached to the surface of the heating surface of the semiconductor refrigeration sheet. The electric control output end of the controller is electrically connected to the semiconductor refrigeration sheet.

[0019] For the traditional saw with different angle adjustments, when there are branches that cannot be trimmed under the position of the branch to be trimmed, the straight-up-and-down trimming method is not convenient for operation. Therefore, the following is a specific implementation plan of the olive tree pruning device according to the present application with reference to the accompanying drawings:

[0020] In a preferred embodiment of the present invention, a hinge seat is fixed on the outer surface of the box body. A rotating shaft is rotatably inserted into the hinge seat. An end of the support rod is fixed with a hinge block, and the hinge block is fixedly connected to the rotating shaft.

[0021] One end of the rotating shaft is coaxially fixed with a worm gear. The box body is rotatably installed with a worm, and the worm meshes with the worm gear. One end of the worm is provided with a driver for driving its rotation.

[0022] In a preferred embodiment of the present invention, the driver is a handwheel or a stepping motor. The stepping motor is fixed to the box body, and the drive shaft of the stepping motor is coaxially fixed to one end of the worm.

[0023] By controlling the rotation of the worm to drive the rotation of the worm gear, the box body rotates around the upper end of the support rod, realizing the adjustment of the angle of the saw to adapt to the trimming of support rods at different positions, simplifying the trimming steps of the support rods.

[0024] In a preferred embodiment of the present invention, a pin shaft is fixed on the outer surface of the box body. A pin hole opened at one end of the cover plate is rotatably sleeved with the pin shaft, and a torsion spring for driving the cover plate to reset is installed at the rotational mating part of the cover plate and the pin shaft.

[0025] During the process of looking up for pruning, sawdust is likely to get into the eyes of the staff. Therefore, the following refers to the specific implementation of the pruning device for olive planting according to the present application with reference to the attached drawings:

[0026] In a preferred embodiment of the present invention, a negative pressure suction assembly is further included. The negative pressure suction assembly includes a negative pressure hood, a suction pump, and a filter box. The negative pressure hood covers the surface of the limiting groove.

[0028] By starting the suction pump, a negative pressure state is created at the negative pressure hood, driving the surrounding air flow to flow into the negative pressure hood. The wood chips generated during the sawing of the tree are adsorbed into the negative pressure hood under the drive of the air flow and enter the filter box through the diversion pipe. At the same time, the wood chips are collected to avoid their diffusion, greatly reducing the impact of the falling wood chips on the environment and the staff.

[0029] The filter box is designed to be pull-out, facilitating the removal of the accumulated wood chips inside for cleaning. At the same time, the filter screen at the bottom of the filter box can also be disassembled for maintenance, with convenient operation. The suction causes the air flow to carry away the wood chips, and the flowing air can cool the saw blade. The filtered gas discharged from the tail dissipates heat to cool the reduction motor.

[0030] In a preferred embodiment of the present invention, a diversion pipe is connected between the suction end of the suction pump and the negative pressure hood. There are two negative pressure hoods, namely a fixed hood and a movable hood. The movable hood is connected to the fixed hood through a telescopic pipe, and the movable hood slides along the direction of the limiting groove.

[0031] By setting a fixed hood at the baffle, the adsorption of the wood chips at one end of the support rod is realized. The set movable hood can be adjusted by sliding according to the thickness of the support rod, so that the fixed hood and the movable hood are respectively located at the two edge positions of the support rod, achieving a better effect of adsorbing wood chips.

[0067] By controlling the rotation of the worm 103 to drive the rotation of the worm wheel 193, the box body 100 is rotated around the upper end of the support rod 510, so as to adjust the angle of the saw 110 to adapt to the pruning of support rods at different positions, simplify the support rod pruning steps, and the driver 105 uses a stepping motor to control the rotation of the drive shaft 191, without manual holding and driving, saving time and effort. The control panel 170 installed through the rod sleeve 530 can operate the rotation angle, and the angle adjustment can be synchronously controlled during the process of sawing branches to achieve precise pruning operations. And when not in use, the saw 110 can be rotated to one side of the rod sleeve 530 through angle adjustment, reducing the overall length, facilitating carrying and storage. At the same time, the rod sleeve 530 blocks the serrated part of the saw 110, and also avoids being scratched by the serrations during the carrying process.

[0068] In a specific embodiment of the present invention, a pin shaft is fixed to the outer surface of the box body 100, a pin hole opened at one end of the cover plate 120 is rotatably sleeved and matched with the pin shaft, and a torsion spring 101 for driving the cover plate 120 to reset is installed at the rotation matching position of the cover plate 120 and the pin shaft.

[0069] During the process of looking up for pruning, sawdust is likely to get into the eyes of the staff. For this reason, the following refers to the accompanying drawings according to the specific implementation scheme of the pruning device for olive planting in the present application:

[0072] It is started by the suction pump 730, so that a negative pressure state is created at the negative pressure hood 710, driving the surrounding air flow to flow into the negative pressure hood 710. The wood chips generated during the sawing of the saw 110 are adsorbed into the negative pressure hood 710 under the drive of the air flow, and enter the filter box 750 through the diversion pipe 770. At the same time, the wood chips are collected to avoid the diffusion of the wood chips, greatly reducing the impact of the falling wood chips on the environment and the staff.

[0073] The filter box 750 is designed to be pullable, which is convenient for taking out and cleaning the accumulated wood chips inside.
