Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, and more particularly to a mixing spraying device for agricultural planting. Background Art

[0002] Planting refers to plant cultivation, including the cultivation of various crops, trees, fruit trees, flowers, medicinal and ornamental plants, including food crops, cash crops, vegetable crops, green manure crops, feed crops, forage, etc.

[0003] Existing agricultural planting equipment requires spraying pesticides or water on crops. Currently, the sprayers carried by humans generally have a small capacity and are not suitable for spraying crops over a large area.

[0004] Chinese patent publication number CN216567510U discloses a mixed spraying device for agricultural planting. The device comprises a second motor, a first gear, a fixing plate, a second gear, a second connecting pipe, a hose, an atomizing nozzle, a first slide bar, and a turntable. The second motor drives the first and second gears to rotate, which in turn rotates the second connecting pipe and the turntable, thereby rotating the atomizing nozzle. This allows for spraying crops at multiple angles, improving crop spraying efficiency.

[0005] Although this mixed spraying equipment for agricultural planting can improve the efficiency of spraying crops, it is unable to fully spray fruit trees during actual use, and spraying blind spots are prone to occur, especially for shrub fruit trees, whose crowns grow in a spherical shape, and the growth heights and crown sizes of fruit trees of different ages are also different. If the liquid medicine is sprayed from the head of the fruit tree by rotating the atomizing nozzle, the liquid medicine can only be sprayed on the upper half of the branches and leaves, and cannot be sprayed on the lower half of the branches and leaves of the spherical crown, resulting in a spraying blind spot, which affects the growth of the fruit trees and the prevention of diseases and pests.

[0045] By adopting the above technical solution, in order to enhance the adaptability of the equipment to different working environments, thereby enhancing the spraying efficiency of the equipment, this solution sets a driving mechanism, uses motor 11 as a power source, drives shaft 1 5 to rotate, thereby carrying transmission gear 1 6 to rotate, and transmission gear 1 6 cooperates with transmission gear 2 9 on shaft 2 8, so that crawler 10 is operated and the driving equipment is moved. The setting of crawler 10 can enhance the adaptability of the equipment to different working environments and relatively improve the practicality of the equipment. Specifically: by controlling The main board 3 starts the motor 11, causing the output shaft of the motor 11 to carry the gear 2 12 to rotate, and the gear 2 12 is meshed with the gear 3 14 for transmission, thereby driving the gear 3 14 to rotate, and the gear 3 14 is meshed with the gear 1 57 on the rotating shaft 1 5, thereby driving the rotating shaft 1 5 to rotate, thereby causing the rotating shaft 1 5 to carry the two sets of transmission teeth 1 6 to rotate, and the transmission teeth 1 6 are meshed with the transmission teeth 2 9 on the rotating shaft 2 8 through the crawler 10 for transmission, and under the drive of the transmission teeth 1 6, the crawler 10 is driven to roll, so that the equipment moves.

[0046] like Figure 10 and Figure 8As shown, the spraying mechanism includes a sleeve 15 provided on the right side of the motor 11, the sleeve 15 is fixedly connected to the support plate 1, the right end of the sleeve 15 is rotatably connected to the connecting shaft 17, the connecting shaft 17 is fixedly connected to the gear 2 12, and a transmission column 16 is provided on the right side of the interior of the sleeve 15. The connecting shaft 17 passes through and extends to the interior of the sleeve 15 and is fixedly connected to the transmission column 16. The outer surface of the transmission column 16 is an inclined ring with a transmission groove 18, and the transmission groove 18 is connected from head to tail. The interior of the transmission groove 18 is slidably connected to a slide rod 19, and a push rod 20 is fixedly installed on the upper end of the slide rod 19.

The spraying mechanism also includes multiple groups of atomizing nozzles 52 fixedly installed at the left end of the arc plate 50, and a telescopic connecting pipe 59 is fixedly installed between the two groups of support guard plates 48. The telescopic connecting pipe 59 is connected with the multiple groups of atomizing nozzles 52, and the output pipe 23 is connected with the telescopic connecting pipe 59.

[0047] By adopting the above technical solution, the existing agricultural planting device needs to spray medicine or water on crops. The current manual sprayers generally have a small capacity and are not suitable for spraying crops over a large area. Therefore, this solution sets up a spraying mechanism. The motor 11 drives the device to move and at the same time drives the spraying mechanism to operate, sucks the stirred pesticide, and pumps it to each group of atomizing nozzles 52 after pressurization for atomization treatment, so as to spray it to the tree crown to complete the pesticide spraying operation. There is no need for manual spraying, which relatively improves the spraying efficiency. Specifically: Gear 2 12 is fixedly connected to the connecting shaft 17, and will drive the connecting shaft 17 to rotate synchronously. The rotation of the connecting shaft 17 will drive the transmission column 16 to rotate. The rotation of the transmission column 16 causes the sliding rod 19 slidably connected to the transmission groove 18 inside the transmission groove 18 to be displaced through the transmission groove 18 opened on the outer surface. The displacement of the slide rod 19 will push the push rod 20 to reciprocate inside the sliding sleeve 21. One end of the push rod 20 is fixedly connected to the piston plate 22, which then makes the piston plate 22 reciprocate inside the sleeve 15. When the piston plate 22 moves to the right, the one-way input valve inside the input pipe 24 will be opened, so that the pesticide stirred inside the mixing barrel 2 will be introduced into the sleeve 15 through the input pipe 24. When the piston plate 22 moves to the left, the pesticide inside the sleeve 15 will be pressurized. When the threshold value of the pesticide is greater than the threshold value of the one-way output valve set inside the output pipe 23, the one-way output valve in the output pipe 23 will be opened, so that the pressurized pesticide in the sleeve 15 will be discharged into the telescopic connecting pipe 59 through the output pipe 23, and sprayed out after being atomized by the atomizing nozzle 52 to spray the pesticide on the crown of the fruit tree.

[0048] like Figure 5 and Figure 6 As shown, a hydraulic lifter 26 is fixedly installed on the upper end surface of the mixing barrel 2, and a lifting platform 31 is fixedly installed on the upper end surface of the hydraulic lifter 26. A motor 27 is fixedly installed on the front side of the outer surface of the hydraulic lifter 26. The motor 27 and the lower end surface of the motor 27 are provided with a drive shaft 28. The outer surface of the drive shaft 28 is sleeved with a support sleeve 29, and the support sleeve 29 is fixedly connected to the mixing barrel 2. The upper end of the support sleeve 29 is rotatably connected to the gear ring 30, and a ratchet mechanism is provided between the gear ring 30 and the drive shaft 28. The motor 11, the motor 27 and the hydraulic lifter 26 are all connected to the control main board 3 through wires. The stirring mechanism includes a plurality of stirring rods 58 arranged inside the mixing barrel 2. The drive shaft 28 passes through and extends to the interior of the mixing barrel 2 and is fixedly connected to the plurality of stirring rods 58. The plurality of stirring rods 58 are arranged in a ring-shaped and dispersed manner.

[0049] By adopting the above technical solution, in order to avoid insufficient mixing of pesticides, thereby affecting the spraying efficiency of the equipment, this solution sets a stirring mechanism, uses motor 27 as a power source, drives the drive shaft 28 carrying the stirring rod 58 to rotate at high speed, and fully mixes the groups of pesticide raw materials poured into the stirring barrel 2, so as to avoid uneven mixing of the raw materials and affect the effect of the pesticide. Specifically: when it is necessary to use this equipment, pesticides and water are poured into the stirring barrel 2 in sequence through the feed port 25, and then the motor 27 is started to make the drive shaft 28 of the motor 27 rotate at high speed. When the drive shaft 28 rotates, it simultaneously carries the stirring rod 58 to rotate at high speed, thereby stirring and mixing the pesticides.

[0050] like Figure 1 、 Figure 3 、 Figure 12 、 Figure 13 and Figure 2As shown, the lifting transmission mechanism includes a rotating rod 34 provided on the right side of the gear ring 30, the rotating rod 34 is rotatably connected to the mixing barrel 2, and a gear five 35 is fixedly installed on the lower side of the outer surface of the rotating rod 34, and the gear five 35 meshes with the gear ring 30. The upper end of the rotating rod 34 is fixedly installed with a transmission long gear 36, the front end of the lifting platform 31 is rotatably connected to the rotating shaft three 32, the lower end of the rotating shaft three 32 is fixedly installed with a gear four 33, and the gear four 33 meshes with the transmission long gear 36, and the upper end of the rotating shaft three 32 is fixedly installed with a worm 37. The adjustment mechanism includes a support member three 38 fixedly installed on the front and rear sides of the upper end of the lifting platform 31, and a reciprocating screw rod 39 is rotatably connected between the two groups of support members three 38. The front end of the reciprocating screw rod 39 is fixedly installed with a gear six 40, and the gear six 40 meshes with the worm 37. The outer front side of the reciprocating screw rod 39 is spirally connected with a threaded sleeve one 41, and the outer surface of the threaded sleeve one 41 rotates on the left and right sides. The outer surface of the reciprocating screw rod 39 is connected to the threaded sleeve 2 43 by a spiral transmission. The outer surface of the threaded sleeve 2 43 is rotatably connected to the connecting rod 2 44 on both the left and right sides. The left and right sides of the reciprocating screw rod 39 are provided with a top block 45. A group of connecting rods 1 42 and a group of connecting rods 2 44 are rotatably connected to the corresponding top blocks 45. The adjustment mechanism also includes a slide rail 47 fixedly installed in the middle of the left end face and the middle of the right end face of the lifting platform 31. The top block A cross bar 46 is fixedly installed on the left end of 45, and the cross bar 46 is slidably connected to the inside of the slide rail 1 47. Support guard plates 48 are fixedly installed on the left side of the front end face and the left side of the rear end face of the slide rail 1 47. Slide rail 2 49 is opened on the inner side of the two sets of support guard plates 48. The inside of the slide rail 2 49 is slidably connected with an arc plate 50. There are two sets of slide rail 2 49 and the arc plate 50 and they are symmetrically arranged. A connecting rod 51 is rotatably connected between one end of the arc plate 50 and one end of the cross bar 46.

[0051] By adopting the above technical solution, the existing Chinese patent with authorization publication number CN216567510U discloses a mixed spraying device for agricultural planting. Although it can improve the efficiency of spraying crops, it is difficult to fully spray fruit trees during actual use, and spraying dead angles are prone to occur. In particular, for shrub fruit trees, the crowns of fruit trees grow in a spherical shape, and the production heights and crown sizes of different fruit trees are also different. If the atomizing nozzle 52 is simply rotated to spray the liquid medicine from the top of the fruit tree, the liquid medicine can only be sprayed on the upper half of the branches and leaves, and cannot be sprayed on the branches and leaves in the lower half of the spherical crown, resulting in spraying dead angles and affecting the growth of the fruit trees.

[0052] Therefore, this solution sets an adjustment mechanism, utilizes a lifting transmission mechanism, a ratchet mechanism and a second motor 27 for transmission connection, so that the second motor 27 rotates counterclockwise to drive the adjustment mechanism to operate, and performs practical adjustment according to the crown size of different fruit trees, thereby increasing the spraying efficiency of pesticides, avoiding the occurrence of spraying blind spots, and relatively improving the spraying effect of the equipment. Secondly, this solution sets a lifting transmission mechanism, which can be adaptively adjusted according to the different production heights of different fruit trees, and after adjustment, the transmission effect of the adjustment mechanism and the ratchet mechanism can be maintained without being disconnected due to changes in height, thereby relatively improving the practicality of the equipment.

[0053] Specifically: the drive shaft 28 carries the gear ring 30 to rotate, and the gear ring 30 engages with the gear five 35 on the rotating rod 34 to transmit the transmission, so that the rotating rod 34 rotates, and the rotating rod 34 carries the transmission long gear 36 to rotate, and then drives the hydraulic lifter 26 to carry the lifting platform 31 to adjust the height through the control motherboard 3, so that the atomizing nozzle 52 of the equipment is adaptively adjusted to the height of the tree crown. When the lifting platform 31 adjusts the height, it will carry the rotating shaft 32 to move, and the gear four 33 fixed at the lower end of the rotating shaft 32 is in a meshing state with the transmission long gear 36. When the height of the lifting platform 31 is adjusted by the rotating shaft 32 carrying the gear 4 33, the gear 4 33 is always in a meshing state with the long transmission gear 36. Therefore, when the height adjustment is completed, the long transmission gear 36 rotates and rotates the rotating shaft 32 through the meshing state with the gear 4 33. The rotating shaft 32 rotates and drives the worm 37 to rotate. The gear 6 40 fixed at the front end of the reciprocating screw 39 is in a meshing state with the worm 37. Therefore, under the action of the worm 37 and the gear 6 40, the rotating shaft 32 drives the reciprocating screw 39 to rotate.

[0054] The front side of the reciprocating screw rod 39 is spirally driven with a threaded sleeve 1 41, and the rear side of the reciprocating screw rod 39 is spirally driven and connected with a threaded sleeve 2 43. When the reciprocating screw rod 39 rotates, since the reciprocating screw rod 39 is a mirror image reciprocating screw rod 39, the threaded sleeve 1 41 and the threaded sleeve 2 43 will continuously switch between opposite movement and relative movement. The displacement of the threaded sleeve 1 41 will cause the two groups of connecting rods 1 42 to move, and the displacement of the threaded sleeve 2 43 will cause the two groups of connecting rods 2 44 to move. One group of connecting rods 1 42 and one group of connecting rods 2 44 are rotatably connected to the corresponding top blocks 45. Therefore, when the threaded sleeve 1 41 and the threaded sleeve 2 43 move toward each other, the top block 45 will push the cross bar 46 to move outward inside the slide rail 1 47. When the threaded sleeve 1 41 and the threaded sleeve 2 43 move relative to each other, the top block 45 will push the cross bar 46 to move inward inside the slide rail 1 47.

[0055] When the cross bar 46 is displaced outward, the arc plate 50 is pushed outward inside the support guard plate 48 through the connecting rod 51, thereby expanding the semicircular area formed by the two groups of arc plates 50. When the arc plate 50 is displaced, the atomizing nozzle 52 is moved with it, and the atomizing nozzle 52 is inclined toward the slide rail 47, thereby expanding the spraying area of ​​the equipment on the crown of the fruit tree. Secondly, when the top block 45 carries the cross bar 46 to displace inward, the setting of the connecting rod 51 that is rotatably connected to the upper and lower ends of the cross bar 46 enables the arc plate 50 to slide inside the support guard plate 48 toward the slide rail 47, thereby reducing the spraying area of ​​the atomizing nozzle 52, thereby adaptively adjusting the crowns of fruit trees of different sizes.

[0056] like Figure 14 and Figure 15 As shown, the ratchet mechanism includes a connecting member 53 fixedly installed on the inner side of the gear ring 30, one end of the connecting member 53 is rotatably connected to a pawl 1 54, a pawl 2 56 is fixedly installed on the outer surface of the drive shaft 28 corresponding to the pawl 1 54, and a spring 55 is fixedly installed between the pawl 1 54 and the inner wall of the gear ring 30. The ratchet mechanism is provided with multiple groups and is dispersedly arranged in a ring shape.

[0057] By adopting the above technical solution, this solution sets a ratchet mechanism, which can make the forward rotation of the drive shaft 28 not drive the lifting transmission mechanism, but only drive the stirring mechanism normally. The reverse rotation of the drive shaft 28 will simultaneously drive and connect the lifting transmission mechanism and the stirring mechanism, thereby relatively improving the practicality of the equipment. Specifically: first, when it is necessary to use this equipment, pesticides and water are poured into the interior of the mixing barrel 2 through the feed port 25, and then the motor 27 is started to rotate the drive shaft 28 of the motor 27 at high speed. The forward rotation of the drive shaft 28 will carry the ratchet 2 56 to rotate. The ratchet 2 56 will then be in close contact with the ratchet 1 54 on the connecting piece 53 and squeeze the ratchet 1 54 so that the ratchet 1 54 moves around the connecting piece 53. When the driving shaft 28 rotates, it simultaneously carries the stirring rod 58 to rotate at high speed, thereby stirring and mixing the pesticide. When the mixing is completed, the driving shaft 28 of the motor 27 rotates in the opposite direction. At this time, the driving shaft 28 will carry the pawl 2 56 to rotate in the opposite direction. At this time, the pawl 2 56 and the pawl 1 54 are engaged with each other, so that the pawl 1 54 has a tendency to deflect in the opposite direction around the connecting member 53, but the left end of the connecting member 53 is fixedly installed with a baffle, which can limit the pawl 1 54, so that the pawl 1 54 cannot deflect in the opposite direction, and then it can be engaged with the pawl 2 56 to transmit the drive shaft 28 and the gear ring 30 to rotate.

[0058] Instructions for use: First, when the device is needed, pour pesticide and water into the mixing barrel 2 in sequence through the feed port 25, then start the motor 27, so that the drive shaft 28 of the motor 27 rotates at high speed. The drive shaft 28 rotates forward through the ratchet mechanism, and will not carry the gear ring 30 to rotate. When the drive shaft 28 rotates, it simultaneously carries the stirring rod 58 to rotate at high speed, thereby stirring and mixing the pesticide. When the mixing is completed, the hydraulic lifter 26 is driven by the control main board 3 to carry the lifting platform 31 for height adjustment, so that the atomizing nozzle 52 of the equipment is adaptively adjusted to the height of the tree crown. When the height adjustment is completed, the semicircular area composed of the two groups of arc plates 50 is expanded through the adjustment mechanism. When the arc plate 50 is displaced, the atomizing nozzle 52 will be carried to move, and the atomizing nozzle 52 is tilted toward the slide rail 1 47, thereby expanding the equipment's spraying of the fruit tree crown. Area, when the adjustment is completed, by starting the motor 11, the output shaft of the motor 11 carries the gear 2 12 to rotate, the gear 2 12 is meshed with the gear 3 14 for transmission, and then drives the gear 3 14 to rotate, and the gear 3 14 is meshed with the gear 1 57 on the rotating shaft 1 5, so it will drive the rotating shaft 1 5 to rotate, thereby causing the rotating shaft 1 5 to carry two sets of transmission teeth 1 6 to rotate, and the transmission teeth 1 6 are meshed with the transmission teeth 2 9 on the rotating shaft 2 8 through the crawler 10 for transmission. Under the drive of the transmission teeth 1 6, the crawler 10 is driven to roll, so that the equipment moves, and the gear 2 12 is fixedly connected to the connecting shaft 17, which will drive the connecting shaft 17 to rotate synchronously, and the connecting shaft 17 will drive the spraying mechanism to operate, so that the pesticide in the mixing barrel 2 is discharged into the telescopic connecting pipe 59 after being pressurized, and is sprayed after being atomized by the atomizing nozzle 52 to spray the pesticide on the crown of the fruit tree.
