Description

Technical Field

[0001] The utility model relates to the technical field of farmland fertilization devices, in particular to a biogas liquid sprinkler. Background Art

[0002] Sprinkler irrigation is a method of irrigation or fertilization that uses special equipment such as sprinklers to spray liquid onto plants. Sprinklers are also called sprinkler equipment or sprinkler units, which are special equipment used for sprinkler irrigation.

[0003] In the prior art, Chinese utility model patent No. CN210432411U discloses a winch-type, anti-clogging sprinkler specifically for biogas slurry. The sprinkler comprises a winch vehicle and a spray vehicle. This prior art utilizes a separate biogas slurry coil, a water coil, and a mixing chamber to prevent the spray gun from becoming clogged by viscous biogas slurry and undissolved solid fertilizer during use. However, the spray gun in this prior art sprinkler cannot rotate automatically during use and requires manual rotation, which is inconvenient. Furthermore, if the spray gun is not rotated, the spray coverage area is smaller, resulting in lower spraying efficiency. Utility Model Content

[0004] In view of the above problems, the present invention provides a biogas slurry sprinkler to solve the problem in the prior art that the spray gun cannot rotate automatically, which is inconvenient to use. If it does not rotate, the radiation area of the sprinkler is small and the efficiency is low.

[0005] The utility model is realized by using the following technical scheme: a biogas slurry sprinkler, comprising a horizontal frame, a spray gun mounted on the horizontal frame, legs mounted at both ends of the horizontal frame, tires mounted at the bottom of the legs, a mounting frame fixedly mounted on the horizontal frame, a mounting box fixedly mounted on the mounting frame, a connecting pipe rotatably driven by a first driving mechanism mounted in the mounting box, the bottom end of the connecting pipe being rotatably connected to and communicated with a hose of a winch truck, and the top end of the connecting pipe being fixedly connected to and communicated with the spray gun.

[0006] Through the above structure, the spray gun in the device can be driven to rotate by the first driving mechanism during the spraying process without manual rotation, thereby making the device more convenient to use; the rotation of the spray gun will also make the radiation area of the spraying wider, thereby increasing the efficiency of the spraying.

[0007] Furthermore, the drive mechanism includes rotating plates rotatably mounted on the upper and lower surfaces of the mounting box. The connecting tube has two ends fixedly connected to the upper and lower rotating plates, respectively, and bevel gears fixedly mounted on the inner surfaces of both rotating plates. A motor is also fixedly mounted on one side of the mounting box, and the motor's output shaft extends through the side wall of the mounting box and is fixedly connected to an incomplete bevel gear mechanism that mates with the bevel gears. Driven by the motor, the spray gun's rotation can be more conveniently controlled, and rotation can be stopped at any time, allowing it to adapt to different types of soil. Furthermore, the incomplete bevel gear mechanism drives the upper and lower bevel gears, enabling the spray gun to reciprocate.

[0008] Furthermore, the incomplete bevel gear mechanism includes a continuous tooth portion and a smooth portion, the tooth portion meshing with the bevel gear; the tooth portion occupies an angle of 150° on the incomplete bevel gear mechanism. The meshing of the gear portion and the bevel gear enables the incomplete bevel gear mechanism to drive the rotating plate to reciprocate, thereby expanding the spray gun's radiation area.

[0009] Furthermore, the spray gun includes a fixed sleeve fixedly mounted on the rotating plate, a main nozzle fixedly mounted on the inner side of the fixed sleeve, the main nozzle is fixedly connected and communicated with the connecting pipe, and a nozzle is provided at one end of the main nozzle away from the fixed sleeve.

[0010] Furthermore, the nozzle is equipped with a rotatable water breaker. A mounting sleeve is fixedly mounted on the main nozzle. The middle portion of the water breaker is rotatably connected to the mounting sleeve. A second mounting block is rotatably mounted on the end of the water breaker away from the nozzle. The second mounting block is fixedly connected to the fixed sleeve. The installation of the water breaker further disperses the biogas slurry sprayed from the spray gun, making the irrigation more uniform.

[0011] Furthermore, the fixing sleeve is fixedly mounted with a first mounting block, on which a transmission shaft rotatably mounted and driven by a second drive mechanism is rotatably mounted. A cam is fixedly mounted on the end of the transmission shaft away from the nozzle. A connecting block is fixedly mounted on the end of the water breaker away from the nozzle, and the connecting block is overlapped with the cam. The rotation of the cam drives the connecting block to rotate, and in turn drives the water breaker to rotate, thereby allowing the installation position of the second drive mechanism to be more flexible.

[0012] Furthermore, the second drive mechanism includes a secondary nozzle connected to the main nozzle. The secondary nozzle is fixedly connected to a mounting sleeve, and a worm gear transmission mechanism is fixedly mounted on the mounting sleeve. The output end of the worm gear transmission mechanism is fixedly connected to the drive shaft, and the input end of the worm gear transmission mechanism is mounted with an impeller. The impeller cooperates with the secondary nozzle, and the nozzle of the secondary nozzle is oriented toward a position not centered on the impeller. The secondary nozzle drives the impeller to provide power for the rotation of the water breaker, so that the device does not require additional external force to drive, which is more energy-efficient.

[0013] Furthermore, a torsion spring is fixedly mounted on the second mounting block, and one end of the torsion spring away from the second mounting block is fixedly connected to the connecting block. The installation of the torsion spring prevents the connecting block from being stuck, thereby ensuring that the connecting block can always overlap the cam.

[0014] Furthermore, the mounting frame includes mounting plates located on both sides of the horizontal frame, and the two mounting plates are fixedly connected by bolts. The arrangement of the bolts and the two mounting plates allows the mounting frame to be freely adjusted on the horizontal frame, thereby increasing the applicability of the device.

[0015] Furthermore, a spray gun holder is fixedly mounted on the bottom of the mounting box, and a counterweight is fixedly mounted on one end of the spray gun holder away from the mounting box. The counterweight balances the pulling force when the winch retracts the pipe, preventing the device from being pulled down during the retraction.

[0016] In summary, the beneficial effects of the present invention are:

[0017] 1. The motor controls the incomplete bevel gear mechanism and the upper and lower bevel gears, allowing the rotating plate in this device to rotate back and forth, thereby controlling the spray gun's reciprocating rotation. This eliminates the need for direct human intervention, allowing the spray gun to irrigate a wider area. Furthermore, the motor can be controlled to stop rotation at any time, allowing it to adapt to different soil types.

[0018] 2. By extending a secondary nozzle from the main nozzle to serve as the power source for the water breaker, no additional driving power is required, thus saving manufacturing costs. The impeller can also disperse the biogas slurry sprayed from the secondary nozzle, so that the biogas slurry sprayed from the secondary nozzle falls evenly back to the ground, thus avoiding waste.

DETAILED DESCRIPTION

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0027] The following is a description of preferred embodiments of the present invention with reference to the accompanying drawings.

[0028] like Figure 1 、 Figure 2 、 Figure 3As shown, the utility model discloses a biogas slurry sprinkler, comprising a horizontal frame 1, on which a spray gun 3 is mounted, legs 11 mounted at both ends of the horizontal frame 1, and tires 12 mounted at the bottom of the legs 11. Specifically, the ends of the horizontal frame 1 are hollowed out, and the legs 11 are inserted into the horizontal frame 1. The horizontal frame 1 and the legs 11 are fixed by bolts. The legs 11 are provided with a plurality of threaded holes. Before use, the position of the legs 11 is adjusted and then fixed to the horizontal frame 1. This allows the device to adjust the width between the two tires 12, making it more adaptable to farmland of different widths and increasing the applicability of the device. A mounting frame is fixedly mounted on the horizontal frame 1, and fixing plates 14 are fixedly mounted on both sides of the mounting frame. An installation box 2 is fixedly mounted between the two fixing plates 14. A connecting pipe 24 that can be driven and rotated by a first drive mechanism is installed in the installation box 2. The bottom end of the connecting pipe 24 is rotatably connected to and communicates with a hose 18 of a winch vehicle, and the top end of the connecting pipe 24 is fixedly connected to and communicates with the spray gun 3.

[0029] The first drive mechanism described above includes rotating plates 23 rotatably mounted on the upper and lower surfaces of the installation box 2. The top rotating plate 23 is fixedly connected to the spray gun 3, while the bottom rotating plate 23 is rotatably connected to the hose 18. A connecting pipe 24 is fixedly connected to each of the upper and lower rotating plates 23 at each end. The rotating plates 23 are circular, coaxially fixed to the connecting pipe 24, and each plate has a through hole for communication with the connecting pipe 24. Bevel gears 25 are fixedly mounted on the inner surfaces of both rotating plates 23, with the smaller sides of the bevel gears 25 facing the inside of the installation box 2. A motor 21 is also fixedly mounted on one side of the installation box 2, located outside the installation box 2. A support plate 22 is fixedly mounted between the two fixed plates 14 and fixedly connected to the motor 21. The support plate 22 further enhances the stability of the motor 21. The output shaft of the motor 21 extends through the side wall of the installation box 2 and is fixedly connected to a partial bevel gear mechanism 26, which mates with the bevel gear 25.

[0030] As a further illustration of this example, the incomplete bevel gear mechanism 26 includes a continuous gear tooth portion 27 and a smooth portion. The gear tooth portion 27 meshes with the bevel gear 25. The gear tooth portion 27 occupies an angle of 150° on the incomplete bevel gear mechanism 26. When the gear tooth portion 27 meshes with the lower bevel gear 25, the spray gun 3 rotates in the forward direction. When the gear tooth portion 27 rotates to mesh with the upper bevel gear 25, the spray gun 3 rotates in the reverse direction. The forward and reverse directions here are only used to describe the difference in the rotation directions. In addition, the 150° angle occupied by the gear tooth portion 27 is not unique. It is only 150° in this embodiment. The specific angle needs to be determined according to actual usage. The incomplete bevel gear mechanism 26 with different angles needs to be replaced according to the needs of the site.

[0031] like Figure 1 、 Figure 2 、 Figure 4 As shown, the spray gun 3 includes a fixed sleeve 31 fixedly mounted on the rotating plate 23. A main nozzle 32 is fixedly mounted inside the fixed sleeve 31. That is, the fixed sleeve 31 is placed outside the main nozzle 32, mainly to strengthen the connection between the main nozzle 32 and the connecting pipe 24. The main nozzle 32 is fixedly connected to and communicates with the connecting pipe 24. A nozzle 35 is provided on the end of the main nozzle 32 away from the fixed sleeve 31.

[0032] A rotatable water breaker 36 is also provided at the nozzle 35. The water breaker 36 can further break up the ejected biogas slurry, allowing it to land more evenly on the farmland, thereby improving the uniformity of the irrigation. A mounting sleeve 34 is fixedly mounted on the main nozzle 32. The middle portion of the water breaker 36 is rotatably connected to the mounting sleeve 34. A second mounting block 41 is rotatably mounted on the end of the water breaker 36 away from the nozzle 35. The second mounting block 41 is fixedly connected to the fixed sleeve 31. A first mounting block 40 is also fixedly mounted on the fixed sleeve 31. A transmission shaft 39 that can be driven to rotate by a second drive mechanism is rotatably mounted on the first mounting block 40. A cam 44 is fixedly mounted on the end of the transmission shaft 39 away from the nozzle 35. A connecting block 43 is fixedly mounted on the end of the water breaker 36 away from the nozzle 35. The connecting block 43 overlaps the cam 44.

[0033] As a further illustration of this example, the second drive mechanism includes an auxiliary nozzle 33 connected to the main nozzle 32. The auxiliary nozzle 33 is fixedly connected to the mounting sleeve 34. A worm gear transmission mechanism 38 is also fixedly mounted on the mounting sleeve 34. The output end of the worm gear transmission mechanism 38 is fixedly connected to the transmission shaft 39. An impeller 37 is mounted on the input end of the worm gear transmission mechanism 38. The impeller 37 cooperates with the auxiliary nozzle 33. The nozzle of the auxiliary nozzle 33 is directed toward a non-center position of the impeller 37.

[0034] During sprinkler irrigation, biogas liquid will also be sprayed out from the auxiliary nozzle 33 and sprayed onto the impeller 37, driving the impeller 37 to rotate. The rotation of the impeller 37 will drive the worm in the worm gear transmission mechanism 38 to rotate. The worm drives the transmission shaft 39 to rotate through the worm gear. The cam 44 on the transmission shaft 39 will drive the connecting block 43 to swing up and down, thereby driving the water breaker 36 to rotate.

[0035] To further illustrate this embodiment, a torsion spring 42 is fixedly mounted on the second mounting block 41. The end of the torsion spring 42, remote from the second mounting block 41, is fixedly connected to the connecting block 43. Without the torsion spring 42, the connecting block 43 would simply overlap the cam 44 under the action of gravity. Due to the friction between the water breaker 36 and the second mounting block 41, the water breaker 36 would easily become stuck under the action of gravity alone, making it impossible for the connecting block 43 to maintain a stable overlap with the cam 44. Adding a torsion spring effectively solves this problem.

[0036] like Figure 1 As shown, the mounting frame includes mounting plates 13 located on either side of the horizontal frame 1, and the two mounting plates 13 are fixedly connected by bolts. Before use, the mounting frame can be moved at will by loosening the bolts between the mounting plates 13. When it is in the appropriate position, the bolts are tightened to achieve the adjustment of the mounting frame position.

[0037] A spray gun bracket 15 is also fixedly mounted on the bottom of the mounting box 2 and is fixedly connected to the fixing plate 14. A slide 16 is bolted to the end of the spray gun bracket 15 away from the mounting box 2. The connection between slide 16 and the spray gun bracket 15 is similar to the connection between the cross frame 1 and the support legs 11, allowing for adjustment of the position of slide 16. A counterweight 17 is fixedly mounted on the end of slide 16 away from the spray gun bracket 15. This counterweight 17 balances the pulling force during the winch retraction, preventing the device from being pulled over during retraction.

[0038] The operating principle of this device is as follows: when in use, first move the device to the specified position, then use the winch to reel in the hose 18, so that the device can move on the farmland. During the movement, the device sprays the biogas slurry. When the spraying starts, the remote control motor 21 is started, and the motor 21 drives the incomplete bevel gear mechanism 26 and the bevel gear 25 to transmit, so that the connecting pipe 24 and the two rotating plates 23 rotate, and then drive the spray gun 3 to reciprocate at a certain amplitude.

[0039] In summary, the present invention provides a biogas slurry sprinkler that transmits power through an incomplete bevel gear mechanism 26 and two upper and lower bevel gears 25 controlled by a motor 21, so that the rotating plate 23 in the device can perform reciprocating rotational motion, thereby controlling the spray gun 3 to perform reciprocating rotational motion without the need for direct human intervention, so that the spray gun 3 has a wider radiation area. In addition, the rotation can be stopped at any time through the control of the motor 21, so that it can cope with different types of land; by leading an auxiliary nozzle 33 from the main nozzle 32 as the power source of the water breaker 36, no additional driving power is required, thereby saving manufacturing costs. The impeller 37 can also break up the biogas sprayed from the auxiliary nozzle 33, so that the biogas sprayed from the auxiliary nozzle 33 falls evenly back to the land, thus avoiding waste.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
