Description

Technical Field

[0002] In modern agriculture, with the increasing demand for food due to population growth, relying solely on traditional fertilizers can no longer meet the needs of efficient production. Microbial fertilizers contain beneficial microorganisms, such as nitrogen-fixing bacteria, phosphate-solubilizing bacteria and potassium-solubilizing bacteria, which can improve soil fertility and increase the efficiency of crop nutrient absorption, thereby increasing crop yields and improving crop quality.

[0003] For example, vine plants such as cowpeas have slender stems that can only cling to other objects. When spraying and fertilizing vine crops, traditional fertilization methods usually use a spraying mechanism to automatically spray microbial fertilizers. During the spraying process, the sprayed fertilizers are affected by wind and deviate from the designated area. In addition, the direction of the spraying mechanism is single. For some plants with irregular shapes or obstructions, the sprayed fertilizers are difficult to cover all parts of the plants, including the back and sides of the leaves, which are difficult to spray directly. In addition, traditional linear spraying has a large impact on the plants and is prone to mechanical damage to the plants. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention drives the deflection plate to rotate through the driving shaft inside the water pump, and the deflection plate will drive the two support rods to move during the rotation. Because the support rod is rotatably connected to the deflection plate through the shaft, the end of the support rod will rotate on the deflection plate through the shaft during the movement of the support rod. When one of the support rods pushes the hinge seat to deflect through the shaft, the other support rod pulls the hinge seat on the same side through the shaft, and the hinge seat drives the second rotating sleeve to rotate outside the second fixed shaft, and the second rotating sleeve drives the spray assembly to rotate through the assembly assembly. Because the second rotating sleeve is fixed to the side plate, the side plate pulls the upper ear plate to deflect through the connecting rod, and the ear plate drives the assembly assembly and the spray assembly to rotate through the first rotating sleeve. During this process, the upper and lower spray assemblies can rotate synchronously, and the support The rotation angles of the spraying assemblies on both sides of the frame are opposite, so that it is convenient to change the spraying angle of the spraying assemblies. After the driving shaft of the water pump drives the deflection plate to rotate one circle, the spraying assemblies on the same side rotate back to the initial state respectively. Therefore, when the water pump is working continuously, multiple spraying assemblies can continue to swing respectively to further expand the spraying range and make the spraying wave-shaped. The wave-shaped spraying method can make the liquid medicine form a more uniform coverage on the surface of the plant, reduce the area of ​​omission and repeated spraying, improve the utilization efficiency of the liquid medicine, and make the liquid medicine form a thinner and more uniform liquid film on the surface of the plant, which increases the contact area and adhesion between the liquid medicine and the plant surface, reduces the loss and volatilization of the liquid medicine, and the liquid medicine sprayed in the wave-shaped manner has a smaller impact force, and the risk of mechanical damage to the plant is reduced; 2. The present invention pulls the handle downward to drive the two slide bars to slide in the concave hole. The two slide bars drive the card plate downward through the slide plate, so that the card plate can be separated from the card slot at the bottom of the nozzle, thereby releasing the locking state of the nozzle. At the same time, the elastic force of the first spring supports the top ring so that the top ring can be pushed out of the nozzle, so that the card slot at the bottom of the nozzle can be misaligned with the card plate, and the nozzle can extend out of the assembly sleeve, thereby facilitating the removal of the nozzle. When installing the nozzle, the card seat on one side of the nozzle is inserted into the limiting groove, so that the branch pipe passes through the assembly sleeve and the limiting groove. The rectangular limit groove serves the purpose of limiting the holder and the nozzle, preventing the nozzle from rotating freely inside the assembly sleeve and affecting the spraying and installation stability. When the nozzle is in the arc position of the squeeze card plate, the card plate will move down and will not interfere with the movement of the nozzle. When the slot at the bottom of the nozzle corresponds to the position of the card plate, the slide is supported by the elastic force of the second spring, so that the slide drives the card plate to be stuck in the slot, thereby achieving the purpose of locking the nozzle, thereby facilitating the rapid loading and unloading of the spray assembly, which is beneficial to the daily maintenance or replacement of the spray assembly.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] like Figure 1-2 As shown, a microbial fertilizer spraying device for agricultural planting includes a supporting base plate 1, a microbial fertilizer storage box 2 is fixedly installed on the supporting base plate 1, a scale bar 11 is provided on one side of the microbial fertilizer storage box 2, and a liquid inlet pipe 12 and a liquid discharge pipe 13 are respectively installed under the top and side walls of the microbial fertilizer storage box 2. Walking wheels 14 are respectively installed at the four corners of the bottom of the supporting base plate 1, a push handle 15 is fixedly connected to the supporting base plate 1, and two baffles 16 are fixed on the side of the supporting base plate 1 away from the push handle 15. The two baffles 16 are L-shaped and are located on both sides of the support frame 3.

[0020] The microbial fertilizer is poured into the microbial fertilizer storage box 2 through the liquid inlet pipe 12, and the amount of medicine in the microbial fertilizer storage box 2 is controlled by observing the scale bar 11. The push handle 15 is pushed to make the supporting base plate 1 drive the bottom walking wheel 14 to roll on the ground, so as to move the device to the planting area. At this time, the support frame 3 is located between the two planting areas, and the spraying assembly 9 in the support frame 3 is facing the plants to improve the spraying accuracy. The setting of the baffle 16 can push away the debris in front to facilitate the transfer of the device.

[0021] like Figure 3-5 As shown, a support frame 3 is provided on one side of the microbial fertilizer storage box 2, and the bottom end of the support frame 3 is fixed to one side of the support base plate 1. A drive component 4 is fixedly installed on the side of the microbial fertilizer storage box 2 close to the support frame 3, and the drive component 4 is clamped in the support frame 3.

[0022] The bottom end of the drive assembly 4 is connected to the microbial fertilizer storage box 2. The drive assembly 4 includes a water pump 401, which is fixedly installed on one side of the microbial fertilizer storage box 2. The water outlet of the water pump 401 is connected to a water guide pipe 402, the top of which is connected to a water guide tray 403. The water inlet of the water pump 401 is connected to a water pumping pipe 404, the bottom of which is connected to the microbial fertilizer storage box 2. The water pumping pipe 404 at the bottom of the water pump 401 extracts liquid medicine from the microbial fertilizer storage box 2, and the liquid medicine is introduced into the water guide tray 403 through the water pump 401 and the water guide pipe 402.

[0023] A deflection plate 405 is fixedly connected to the drive shaft of the water pump 401. The other end of the deflection plate 405 is rotatably connected to two support rods 406 via a pin. The end of the support rod 406 away from the deflection plate 405 is rotatably connected to the hinge seat 5 via a pin. When the water pump 401 is working, the internal drive shaft drives the deflection plate 405 to rotate. During the rotation of the deflection plate 405, the two support rods 406 are driven to move. Because the support rods 406 are rotatably connected to the deflection plate 405 via the shaft, the ends of the support rods 406 rotate on the deflection plate 405 via the pin during the movement. When one of the support rods 406 pushes the hinge seat 5 to deflect via the pin, the other support rod 406 pulls the hinge seat 5 on the same side via the pin, thereby facilitating the synchronous adjustment of the hinge seats 5 on both sides.

[0024] A rocking assembly 6 is provided on the top of the articulated seat 5. The rocking assembly 6 includes a connecting rod 601. The top end of the connecting rod 601 is rotatably connected to an ear plate 602 via a pin rod. The end of the ear plate 602 away from the connecting rod 601 is clamped with a first rotating sleeve 604. A first fixed shaft 603 is sleeved inside the first rotating sleeve 604. The first fixed shaft 603 is fixed to both sides of the inner wall of the support frame 3. The bottom end of the connecting rod 601 is rotatably connected to the side plate 605 via a pin. A second rotating sleeve 607 is secured to the end of the side plate 605 away from the connecting rod 601. A second fixed shaft 606 is sleeved within the second rotating sleeve 607. The second fixed shaft 606 is fixed to both sides of the inner wall of the support frame 3. The outer wall of the second rotating sleeve 607 is fixed to the top of the hinge seat 5. The hinge seat 5 drives the second rotating sleeve 607 to rotate around the second fixed shaft 606. Because the second rotating sleeve 607 is fixed to the side plate 605, the side plate 605 pulls the upper ear plate 602 through the connecting rod 601, causing it to deflect, and the ear plate 602 rotates.

[0025] like Figure 6 As shown, an assembly component 7 is fixed on the first rotating sleeve 604 , a spray component 9 is installed through the interior of the assembly component 7 , and one end of the spray component 9 is connected to the water guide plate 403 through a pipeline.

[0026] The assembly component 7 includes an assembly sleeve 701, and a fixed column 702 is fixed on the top of the assembly sleeve 701, and the fixed column 702 is fixedly connected to the first rotating sleeve 604; a limiting groove 703 is opened on one side of the inner wall of the assembly sleeve 701, and the limiting groove 703 is rectangular in design. The rectangular limiting groove 703 serves to limit the end of the spray component 9, preventing the spray component 9 from rotating freely inside the assembly sleeve 701 and affecting the working stability.

[0027] A support assembly 8 is fixedly installed on one side of the inner wall of the assembly assembly 7, the outer wall of the support assembly 8 is slidably connected in the assembly assembly 7, and one side of the support assembly 8 is overlapped with the spray assembly 9. A locking assembly 10 is slidably installed on the bottom of the assembly assembly 7, and the top of the locking assembly 10 is clamped on the bottom of the spray assembly 9.

[0028] The support assembly 8 includes a top ring 801, which is slidably connected in the assembly sleeve 701 and overlaps with the spray assembly 9. A plurality of first springs 802 are fixedly connected to the other side of the top ring 801, and the other end of the first spring 802 is fixed to one side of the inner wall of the assembly sleeve 701.

[0029] The top ring 801 is supported by the elastic force of the first spring 802 so that the top ring 801 can be pushed out of the spray assembly 9, and the nozzle 901 in the spray assembly 9 can extend out of the assembly sleeve 701, thereby facilitating the removal of the spray assembly 9 from the assembly sleeve 701.

[0030] like Figure 7 As shown, the spray assembly 9 includes a nozzle 901, which is inserted into the assembly sleeve 701. A holder 902 is fixed to the side of the nozzle 901 near the assembly sleeve 701. The holder 902 is rectangular and slides through the limiting groove 703. A branch pipe 903 is connected to the nozzle 901. The branch pipe 903 passes through the holder 902 and the assembly sleeve 701 and is connected to the water guide plate 403. Because the branch pipes 903 in multiple spray assemblies 9 are connected to the water guide plate 403, the water guide plate 403 can divert the liquid medicine and guide it into multiple spray assemblies 9, thereby facilitating the simultaneous supply of medicine to multiple spray assemblies 9 and improving the synchronization of liquid medicine spraying.

[0031] When installing the nozzle 901, the holder 902 on one side of the nozzle 901 is inserted into the limiting groove 703, so that the branch pipe 903 passes through the assembly sleeve 701 and the limiting groove 703. The rectangular limiting groove 703 serves the purpose of limiting the holder 902 and the nozzle 901, preventing the nozzle 901 from rotating freely inside the assembly sleeve 701 and affecting the spraying and installation stability.

[0032] like Figure 8As shown, the locking assembly 10 includes a slide 1001, a recessed hole 704 is provided at the bottom of one side of the assembly sleeve 701, the slide 1001 is slidably connected in the recessed hole 704, the top of the slide 1001 is fixedly connected with a card plate 1002, and a card slot 904 is provided at the bottom of the nozzle 901, the card plate 1002 passes through the recessed hole 704 and the assembly sleeve 701 and is clamped in the card slot 904, the side of the card plate 1002 close to the opening of the assembly sleeve 701 is a curved surface design, and the side of the card plate 1002 close to the base 902 is a flat design, and sliding rods 1003 are fixed on both sides of the bottom of the slide 1001, and the bottom ends of the two sliding rods 1003 pass through the recessed hole 704 and are fixed with handles 1004, and a second spring 1005 is connected to the outer sleeve of the slide 1003, and the top of the second spring 1005 is fixed to the bottom of the slide 1001, and the bottom end of the second spring 1005 is fixed to the bottom of the inner wall of the recessed hole 704.

[0033] Pull the handle 1004 downward, so that the handle 1004 drives the two slide bars 1003 to slide in the recessed hole 704. The two slide bars 1003 then drive the card plate 1002 downward via the slide plate 1001, so that the card plate 1002 can be separated from the card slot 904 at the bottom of the nozzle 901, thereby facilitating the unlocking of the nozzle 901 and improving the convenience of operation. When the nozzle 901 moves toward the inside of the assembly sleeve 701, the card plate 1002 will move downward when the nozzle 901 squeezes the arc surface of the card plate 1002, and will not interfere with the movement of the nozzle 901. When the slot 904 at the bottom of the nozzle 901 corresponds to the position of the card plate 1002, the elastic force of the second spring 1005 supports the slide plate 1001, so that the slide plate 1001 drives the card plate 1002 to be stuck in the slot 904, thereby achieving the purpose of locking the nozzle 901 and facilitating the quick loading and unloading of the nozzle 901.

[0034] Working principle of the present invention: When in use, the microbial fertilizer is poured into the microbial fertilizer storage box 2 through the liquid inlet pipe 12, and the amount of medicine in the microbial fertilizer storage box 2 is controlled by observing the scale bar 11. The push handle 15 is pushed to make the support base plate 1 drive the bottom walking wheel 14 to roll on the ground, so as to move the device to the planting area. At this time, the support frame 3 is located between the two planting areas, and the spraying component 9 in the support frame 3 is facing the plants to improve the spraying accuracy. By starting the water pump 401, the water at the bottom of the water pump 401 The water extraction pipe 404 extracts the liquid medicine from the microbial fertilizer storage box 2, and the liquid medicine is introduced into the water guide plate 403 through the water pump 401 and the water guide pipe 402. Since the branch pipes 903 in the multiple spraying components 9 are connected to the water guide plate 403, the water guide plate 403 can divert the liquid medicine and introduce it into the multiple branch pipes 903. The liquid medicine is then injected into the nozzle 901 from the branch pipe 903. The nozzle 901 can expand the spraying range of the liquid medicine, so that the liquid medicine can be sprayed onto the plants over a large range. During the process of spraying the plants with the nozzle 901, the driving shaft inside the water pump 401 will drive the deflection plate 405 to rotate when it is working. The deflection plate 405 will drive the two support rods 406 to move during the rotation. Because the support rods 406 are rotatably connected to the deflection plate 405 through the shaft, the ends of the support rods 406 will rotate on the deflection plate 405 through the shaft during the movement. When one of the support rods 406 pushes the articulated seat 5 to deflect through the shaft, the other support rod 406 pulls the articulated seat 5 on the same side through the shaft, and the articulated seat 5 drives the second support rod 406 to rotate. The sleeve 607 rotates outside the second fixed shaft 606, and the second rotating sleeve 607 drives the spray assembly 9 to rotate through the assembly assembly 7. Since the second rotating sleeve 607 is fixed to the side plate 605, the side plate 605 pulls the upper ear plate 602 to deflect through the connecting rod 601, and the ear plate 602 drives the assembly assembly 7 and the spray assembly 9 to rotate through the first rotating sleeve 604. During this process, the upper and lower spray assemblies 9 can rotate synchronously, and the rotation angles of the spray assemblies 9 on both sides of the support frame 3 are opposite, thereby facilitating the change of the spraying angle of the spray assembly 9; As the driving shaft of the water pump 401 drives the deflection plate 405 to rotate one circle, during this process, the spraying components 9 on the same side respectively rotate to the initial state. Therefore, when the water pump 401 is continuously working, the multiple spraying components 9 can respectively continue to swing to further expand the spraying range, making the spraying in a wave shape. The wave-shaped spraying method can make the liquid medicine form a more uniform coverage on the surface of the plant, reduce the area of ​​omission and repeated spraying, improve the utilization efficiency of the liquid medicine, and make the liquid medicine form a thinner and more uniform liquid film on the surface of the plant, thereby increasing the contact area and adhesion between the liquid medicine and the plant surface, reducing the loss and volatilization of the liquid medicine. During the spraying process, by pushing the push handle 15, the device is driven to slowly move forward between the two planting areas, thereby achieving the purpose of directional spraying and preventing the sprayed liquid medicine from deviating from the designated area; When separating the assembly component 7 and the spray component 9, first unplug the branch pipe 903 from the water guide plate 403, and pull the handle 1004 downward to make the handle 1004 drive the two slide bars 1003 to slide in the recessed hole 704. The two slide bars 1003 drive the card plate 1002 downward through the slide plate 1001, so that the card plate 1002 can be separated from the groove 904 at the bottom of the nozzle 901, thereby releasing the locking state of the nozzle 901. At the same time, the elastic force of the first spring 802 supports the top ring 801, so that the top ring 801 can push out the nozzle 901, so that the groove 904 at the bottom of the nozzle 901 can be misaligned with the card plate 1002, and the nozzle 901 can extend out of the assembly sleeve 701, thereby facilitating the removal of the nozzle 901. When installing the nozzle 901, The holder 902 is inserted into the limiting groove 703, so that the branch pipe 903 passes through the assembly sleeve 701 and the limiting groove 703. The rectangular limiting groove 703 serves to limit the holder 902 and the nozzle 901, preventing the nozzle 901 from rotating freely inside the assembly sleeve 701 and affecting the spraying and installation stability. When the nozzle 901 is in the arc position of the squeezing card plate 1002, the card plate 1002 will move downward and will not interfere with the movement of the nozzle 901. When the slot 904 at the bottom of the nozzle 901 corresponds to the position of the card plate 1002, the slide plate 1001 is supported by the elastic force of the second spring 1005, so that the slide plate 1001 drives the card plate 1002 to be inserted into the slot 904, thereby achieving the purpose of locking the nozzle 901, and then the branch pipe 903 is inserted into the water guide plate 403 for use.
