Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a pruning device for agricultural and forestry planting. Background Art

[0002] In the growth process of agricultural and forestry crops, plant pruning is widely used, which plays a very important role in improving the growth process of plants, greening effects and ornamental value. Mastering the correct pruning method and reasonable pruning can not only cultivate a beautiful tree shape, but also further regulate the reasonable distribution of nutrients through pruning, inhibit excessive growth, promote flower bud differentiation, achieve the effect of improving flowering and fruiting of young trees, and extend the peak flowering and fruiting period, and also make old trees strong.

[0003] Through pruning, you can cut off unnecessary parts, concentrate the supply of nutrients and water, and promote local growth. Excessive pruning can also weaken the overall growth. Through appropriate heavy pruning, combined with fertilization and watering, the germination of latent buds can be promoted, which can be renewed and rejuvenated. In garden landscapes, through proper pruning of the tree shape, it plays a role in beautifying the environment. At the same time, shaping pruning can make the main branches and side branches distributed reasonably, which is conducive to ventilation and lighting, reduce the potential harm of pests and diseases, and avoid damage caused by friction between branches. Reasonable pruning can make plants grow better.

[0004] With the existing pruning devices, after pruning, the staff manually shakes the pruned branches to remove the branches and leaves remaining on the surface, which not only increases the labor of the staff, but also fails to achieve a good cleaning effect. The shaking can easily cause the pruned branches to fall from the surface into the interior of the vegetation. Since the lighting and air permeability inside the vegetation are poor, the branches and leaves are easy to rot and decompose, and then produce harmful substances such as pathogens and insect eggs, which in turn breed mosquitoes, etc., affecting the normal growth of the plants and easily causing environmental damage.

[0014] The beneficial effects of the present invention are:

[0015] 1. In the present invention, the one-way valve 1 inhales external air into the interior of the square air cylinder, and the air inside the square air cylinder passes through the one-way valve 2 and the air inlet pipe into the interior of the air storage cylinder for storage, and then the gas enters the interior of the conical connector through the outlet pipe 1 and the toggle block, and is sprayed out through the connecting pipe and the atomizing nozzle. The chopped branches and leaves can be blown down to the roots through the spraying of gas, which is convenient for cleaning and processing. If the branches and leaves fall into the interior of the vegetation, due to the poor light transmittance and air permeability inside the vegetation, it is easy to cause the branches and leaves to rot and decompose, and then breed bacteria and pests, etc., which endanger the normal growth of the vegetation.

When the moving shaft slides four times, the toggle bar opens the toggle block once, the air outlet pipe of the air storage cylinder is opened, and the gas inside the air storage cylinder enters the conical connector and then sprays out. The air storage cylinder takes in air four times and discharges air once, which increases the pressure of the gas sprayed by the device, thereby increasing the speed of the sprayed gas, and quickly clears the branches and leaves under the blade during the pruning process, ensuring a cleaner and neater pruning effect. Continuous cleaning is also achieved during the pruning process, which reduces the cleaning time and improves the pruning efficiency.

[0018] 4. The present invention accelerates the atomization effect of gas and liquid medicine by connecting the funnel, the conical connector and the filter screen, making the spraying of gas and medicine more uniform and efficient, thereby improving the efficiency of the operation.

During the rotation of the rotating shaft 7, the connecting rod 1 8 rotates around the rotating shaft 7 as the center. Due to the traction of the connecting rod 2 9, the limiter 10 fixedly connected to the surface of the movable blade 10 is The slider 12 slides in the sliding groove 11 on the bottom surface of the fixed blade 4, and the mobile blade 10 and the fixed blade 4 slide back and forth, so that the fixed blade 4 and the mobile blade 10 trim the vegetation. During the rotation of the rotating shaft 7, the bevel gear 13 and the bevel gear 2 14 also rotate synchronously, and the cam 15 is fixedly connected to the bevel gear 2 14, so the cam 15 also rotates continuously, driving the sliding block 16 and the driven rod 17 to reciprocate and extend in the holes of the handle 1 2 and the baffle 3. At this time, the square piston 20 also slides back and forth inside the square air cylinder 18, and also drives the spur rack 21 to slide inside the square air cylinder 18. When the square piston 20 slides inside the square air cylinder 18 toward the direction close to the driven rod 17,At this time, the gas is sucked into the interior of the square gas cylinder 18 through the one-way valve 19.

[0033] Among them, the top surface of the spur rack 21 is meshed with the inner and outer gears 23, and a moving shaft 24 is rotatably connected to the side of the square air cylinder 18 and located at the center of the inner and outer gears 23. The outer walls of both sides of the moving shaft 24 are arranged in a circular array with nine fixedly connected rotating shafts 25.

When the square piston 20 is in the square air cylinder 18 When the interior slides toward the side away from the driven rod 17, the spur rack 21 also slides synchronously inside the square air cylinder 18 toward the side away from the driven rod 17. The sliding of the spur rack 21 drives the inner and outer gears 23 to rotate, and the arc plate 26 rotates on the outer wall of the rotating shaft 25. At this time, the arc plate 26 is not engaged with the inside of the inner and outer gears 23, that is, the moving shaft 24 does not rotate. When the square piston 20 slides inside the square air cylinder 18 toward the side close to the driven rod 17, the spur rack 21 also slides synchronously inside the square air cylinder 18 toward the side close to the driven rod 17. The sliding of the spur rack 21 drives the inner and outer gears 23 to rotate, and the arc plate 26 is engaged with the inner wall of the inner and outer gears 23. At this time, the moving shaft 24 rotates synchronously with the inner and outer gears 23. During the rotation of the moving shaft 24, the small gear 27 and the large gear 28 are also driven to rotate synchronously.

[0034] Among them, the spur rack 21 and the inner and outer gears 23 have the same number of teeth, the bevel gear 1 13 and the bevel gear 2 14 are of the same size, the ratio of the number of teeth between the pinion 27 and the large gear 28 is one to four, the spur rack 21 and the inner and outer gears 23 have the same number of teeth, that is, every time the driven rod 17 drives the square piston 20 to slide once inside the square cylinder 18, the inner and outer gears 23 will rotate one circle, and the bevel gear 1 13 and the bevel gear 2 14 are of the same size, then the rotating shaft 7 rotates one circle, that is, drives the driven rod 17 and the square piston 20 to slide back and forth once inside the square cylinder 18, and when the pinion 27 rotates four times, it can drive the large gear 28 to rotate one circle, so that the rotation between the pinion 27 and the large gear 28 produces a difference.

The surface of the rotating disk 36 is provided with six straight slide grooves 38 in a circumferential array, and the interiors of the six straight slide grooves 38 are all slidably connected with six pin shafts 40, and the bottom surfaces of the six pin shafts 40 are all fixedly connected with six closing plates 39, and the six closing plates 39 can be pieced together to form an equilateral hexagon, and the side of the closing plate 39 away from the pin shaft 40 is fixedly connected with a square slider 41, a side of the square air cylinder 18 close to the air storage cylinder 34 is fixedly connected with a pipe 3501, a side of the pipe 3501 is provided with an air outlet hole 46, a side of the pipe 3501 away from the square air cylinder 18 is fixedly connected with a hollow plate 42, a side of the hollow plate 42 away from the square air cylinder 18 is provided with a hexagonal slide 43, the square sliders 41 are all slidably connected to the surface of the hexagonal slide 43, an air outlet pipe 2 47 is fixedly connected to the inner wall of the air outlet hole 46, the air storage cylinder 34, the air outlet pipe 1 35, the rotating disk 36, the closing plate 39, the hollow plate 42 and the air outlet pipe 2 47 are all in a through connection state, each When the square piston 20 moves once in the square cylinder 18 toward the direction close to the driven rod 17, the one-way valve 19 can inhale air into the square cylinder 18. Then, the square piston 20 moves once in the square cylinder 18 toward the direction away from the driven rod 17, and the air in the square cylinder 18 can enter the air storage cylinder 34 through the air inlet hole 31, the one-way valve 2 32, and the air inlet pipe 33 for storage. After the square piston 20 reciprocates four times, the small gear 27 rotates four times to drive the large gear 28 to rotate one circle, and then the toggle block 29 is driven to rotate the large gear 28. 37 is contacted and toggled. When the toggling is completed, the spring 45 restores the position of the rotating disk 36 due to the elastic force generated by the toggling. During the toggling process, the pin shaft 40 slides toward the outside inside the straight slide groove 38. At the same time, the square slider 41 also slides inside the hexagonal slide groove 43, thereby causing the six closing plates 39 to move toward the periphery, thereby opening the passage between the rotating disk 36 and the hollow plate 42, and the gas inside the gas storage cylinder 34 enters into the gas outlet pipe 2 47 through the gas outlet pipe 1 35, so that the pressure of the gas released in the gas storage cylinder 34 is increased, thereby increasing the flow rate of the jet.

[0036] The top surface of the fixed blade 4 is fixedly connected with a fixed cover 48, the interior of the fixed cover 48 is fixedly connected with a connecting pipe 49, the interior of the fixed blade 4 is penetrated with eleven circular grooves 50 arranged in a uniform array, the bottom surface of the fixed cover 48 and the corresponding position of the circular groove 50 are fixedly connected with an atomizing nozzle 51, the end of the connecting pipe 49 close to the fixed box 1 is fixedly connected with a filter screen 52, the end of the connecting pipe 49 close to the fixed box 1 is fixedly connected with a conical connector 53, the end of the outlet pipe 47 away from the outlet hole 46 is fixedly connected to the surface of the conical connector 53, the outlet pipe 47 and the conical connector 53, the connecting pipe 49, and the atomizing nozzle 51 are all in a through-connected state. The exhausted gas enters the connecting pipe 49 through the outlet pipe 47, the filter 52 and the conical connector 53, and then is sprayed onto the surface of the vegetation through the atomizing nozzle 51. Since the conical connector 53 is conical, the gas can be accelerated to atomize through the filter 52 and the conical connector 53, so that the spraying flow rate is increased. The high flow rate of the sprayed gas can not only blow off the pruned branches and leaves on the surface of the vegetation, but also blow off the dead branches, diseases and insects on the surface of the plants, thereby increasing the light transmittance and air permeability of the plants and promoting the growth of the plants.

[0037] Among them, a medicine box 54 is fixedly connected to the top surface of the square gas cylinder 18, a medicine inlet 55 is opened on the top surface of the medicine box 54, a medicine outlet pipe 56 is fixedly connected to the bottom of the side of the medicine inlet 55, one end of the medicine outlet pipe 56 away from the medicine box 54 is fixedly connected to the surface of the conical connector 53, and one end of the medicine outlet pipe 56 close to the conical connector 53 is fixedly connected to a one-way valve three 58, the medicine box 54, the medicine outlet pipe 56, the one-way valve three 58 and the conical connector 53 are all in a through connection state. When the medicine box 54, the medicine outlet pipe 56, the one-way valve three 58 and the conical connector 53 are all in a connected state, the medicine liquid enters the interior of the connecting pipe 49 through the conical connector 53 and the filter screen 52, and the medicine liquid can be sprayed out together with the gas, which can not only make the gas blow off the branches and leaves remaining on the surface of the vegetation after pruning, but also can spray the plants with medicine, thereby improving the efficiency of labor.

[0038] Among them, a connecting funnel 59 is fixedly connected to the bottom surface of the medicine outlet pipe 56 and is located between the one-way valve three 58 and the conical connector 53. A switch 57 is fixedly connected to the outer wall of the medicine outlet pipe 56 and is located on the side of the one-way valve three 58 away from the conical connector 53. The switch 57, the one-way valve three 58 and the connecting funnel 59 are all in a through-connected state. When it is necessary to spray the vegetation and crops, the switch 57 can be turned on, and the medicine liquid enters the interior of the conical connector 53 through the medicine box 54, the medicine outlet pipe 56 and the switch 57, and can be sprayed on the vegetation with the airflow. When it is not necessary to spray the vegetation and crops, the one-way valve three 58 can be closed, and no medicine liquid will be sprayed out at this time. At the same time, the setting of the connecting funnel 59 can reduce the turbulence and resistance in the liquid flow, which helps to maintain the uniformity of the spraying, and can also help filter out larger particles or impurities to prevent blockage. It can also prevent a small amount of medicine liquid from entering the conical connector 53 for storage during the closing of the switch 57, reducing splashing and waste of medicine liquid.

[0039] The specific working principle and use method of the present invention are explained in detail below: when in use, the staff holds the handle 1 2 and the handle 2 5 to fix the device, and then starts the motor 6 to rotate the rotating shaft 7, thereby driving the connecting rod 1 8 and the connecting rod 2 9 to rotate, so that the movable blade 10 slides inside the sliding groove 11 through the limiting slider 12, so that the movable blade 10 and the fixed blade 4 slide relative to each other, and the vegetation is trimmed by the movement of the movable blade 10 and the fixed blade 4. During the rotation of the rotating shaft 7, the bevel gear 1 13 and the bevel gear 2 14 also rotate synchronously, and the cam 15 also rotates together, driving the movable blade 10 to move relative to the fixed blade 4. The driving rod 17 and the square piston 20 reciprocate in the square cylinder 18. When the square piston 20 slides in the direction close to the driven rod 17 in the square cylinder 18, the one-way valve 19 on the surface of the square cylinder 18 inhales the external gas into the square cylinder 18, and then the square piston 20 slides in the direction away from the driven rod 17 in the square cylinder 18. At this time, the gas in the square cylinder 18 passes through the air inlet hole 31, the one-way valve 2 32 and the air inlet pipe 33 into the air storage cylinder 34. At this time, the square piston 20 completes a cycle of movement, that is, the cam 15 moves one circle, and the square piston 20 moves in the square cylinder 18. When the square cylinder 18 moves in the direction away from the driven rod 17, the sliding of the spur rack 21 does not drive the moving shaft 24 to rotate. Only when the square piston 20 moves in the direction close to the driven rod 17 inside the square cylinder 18, the sliding of the spur rack 21 drives the inner and outer gears 23 and the moving shaft 24 to rotate synchronously, and the small gear 27 and the large gear 28 also rotate synchronously. When the square piston 20 completes four cycles of movement, the large gear 28 rotates one circle, driving the toggle bar 29 to contact the toggle block 37, and then the rotation of the closing plate 39 makes the rotating disk 36 and the hollow plate 42 connected, so that the gas storage The gas inside the cylinder 34 passes through the rotating disk 36, the hollow plate 42, and the air outlet pipe 47 into the conical connector 53 and the connecting pipe 49, and then is sprayed out through the atomizing nozzle 51. If the vegetation needs to be sprayed, first ensure that the switch 57 is closed, and then open the medicine inlet 55 to pour the medicine liquid into the medicine box 54. During the startup of the device, open the switch 57 to allow the medicine liquid to pass through the medicine outlet pipe 56, the switch 57, the one-way valve three 58 and the connecting funnel 59 into the conical connector 53. When there is airflow passing through the conical connector 53, the medicine liquid enters the connecting pipe 49 together with the airflow and is immediately sprayed out, thereby achieving the spraying treatment of the vegetation.
