Description

Technical Field

[0001] The utility model relates to the technical field of spraying machines for cereal planting, in particular to a spraying machine with a self-cleaning mechanism. Background Technique

[0002] A spraying machine is an agricultural machinery that mixes water and liquid medicine and sprays the liquid onto the surface of an object through pressure.

[0003] When planting cereals, a spraying machine is often used to spray medicine. The commonly used spraying machine pumps the liquid medicine in the container through a pump and then sprays it out through a nozzle. However, when spraying, sundries such as leaves are easily adhered to the nozzle, and the user needs to clean it, which is rather inconvenient. Therefore, we propose a spraying machine with a self-cleaning mechanism. Content of the Utility Model

[0004] The purpose of the utility model is to provide a spraying machine with a self-cleaning mechanism to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A spraying machine with a self-cleaning mechanism, including a spraying machine body, a spray pipe is arranged on the spraying machine body, and a self-cleaning mechanism for cleaning the spray pipe is arranged inside and on the surface of the spray pipe.

[0006] Preferably, the self-cleaning mechanism includes: a support plate, the support plate is fixed on the inner wall of the spray pipe, the support plate is penetrated by a rotating rod and is rotatably connected to the rotating rod, the rotating rod penetrates through an impeller and is fixed to the impeller, the right side of the rotating rod is penetrated by a connecting rod and is slidably connected to the connecting rod, a return spring is fixed on the inner wall of the rotating rod, and the end of the return spring away from the rotating rod is fixed on the left side of the connecting rod.

[0007] Preferably, the right side of the connecting rod is rotatably installed inside a rotating sleeve nozzle, a cleaning rod is fixed on the left side of the rotating sleeve nozzle, a transverse groove and an annular groove are opened on the surface of the spray pipe, the transverse groove and the annular groove are communicated with each other, a sliding rod is inserted inside the transverse groove, and the end of the sliding rod away from the spray pipe is fixed to the cleaning rod. When the spraying machine body sprays out the liquid medicine through the spray pipe, the liquid medicine impacts on the impeller to drive the impeller and the rotating rod to rotate, the rotating rod drives the connecting rod to rotate, the liquid medicine impacts on the rotating sleeve nozzle, pushes the rotating sleeve nozzle to move to the right, and the rotating sleeve nozzle drives the cleaning rod to rotate together, and the cleaning rod can clean the surface of the spray pipe to prevent sundries such as leaves from adhering to the surface of the spray pipe.

[0008] Preferably, an opening component is arranged on the rotating sleeve nozzle, and the opening component includes a disc, the disc is penetrated by the connecting rod and is fixed to the connecting rod, and an arc-shaped chute is opened on the disc.

[0009] Preferably, a guiding groove is formed inside the rotating nozzle. A baffle is slidably installed inside the guiding groove. A fixing rod is fixed to the left side of the baffle. The fixing rod is inserted inside the arc-shaped sliding groove. When the connecting rod rotates, the connecting rod drives the disc to rotate together. Since the baffle is limited by the guiding groove, the disc can push the fixing rod and the baffle to move towards the side close to the center of the disc through the arc-shaped sliding groove formed on itself.

[0010] Preferably, sector-shaped holes are formed on both the disc and the rotating nozzle for the liquid medicine to pass through. The sector-shaped hole on the rotating nozzle is blocked by the baffle in the initial state. When the liquid medicine impacts on the rotating nozzle, it first pushes the rotating nozzle to move to the right. During this process, the connecting rod drives the disc to rotate. When it is controlled that the baffle no longer blocks the sector-shaped hole on the rotating nozzle, the liquid medicine can be sprayed through the sector-shaped hole to spray the planted grains. At this time, the connecting rod can drive the rotating nozzle to rotate together through the disc and the baffle.

[0011] Compared with the prior art, the present utility model provides a spraying machine with a self-cleaning mechanism, which has the following beneficial effects:

[0012] 1. For the spraying machine with the self-cleaning mechanism, through the arranged self-cleaning mechanism, when the spraying machine body sprays the liquid medicine through the spray pipe, the liquid medicine impacts on the impeller to drive the impeller and the rotating rod to rotate. The rotating rod drives the connecting rod to rotate. The liquid medicine impacts on the rotating nozzle and pushes the rotating nozzle to move to the right. The rotating nozzle drives the cleaning rod to rotate together, and the cleaning rod can clean the surface of the spray pipe to prevent some sundries such as leaves from adhering to the surface of the spray pipe.

[0013] 2. For the spraying machine with the self-cleaning mechanism, through the arranged self-cleaning mechanism and the opening component, the sector-shaped hole on the rotating nozzle is blocked by the baffle in the initial state. When the liquid medicine impacts on the rotating nozzle, it first pushes the rotating nozzle to move to the right. During this process, the connecting rod drives the disc to rotate. When it is controlled that the baffle no longer blocks the sector-shaped hole on the rotating nozzle, the liquid medicine can be sprayed through the sector-shaped hole to spray the planted grains. At this time, the connecting rod can drive the rotating nozzle to rotate together through the disc and the baffle, so that the rotating nozzle can be rotated only when it receives enough force to move to the right, ensuring that the end surface of the spray pipe can be cleaned. At the same time, through the rotation of the rotating nozzle, the leaf sundries attached to the rotating nozzle can be shaken off. Description of the Drawings

Specific implementation manner

[0020] As Figures 1 - 5 shown, the present utility model provides a technical solution: a spraying machine with a self-cleaning mechanism, including the main body 1 of the spraying machine, a spray pipe 2 is arranged on the main body 1 of the spraying machine, and a self-cleaning mechanism 3 for cleaning the spray pipe 2 is arranged inside and on the surface of the spray pipe 2.

[0021] The self-cleaning mechanism 3 includes: a support plate 31, the support plate 31 is fixed on the inner wall of the spray pipe 2, the support plate 31 is penetrated by the rotating rod 32 and is rotatably connected to the rotating rod 32, the rotating rod 32 penetrates through the impeller 33 and is fixed to the impeller 33, the right side of the rotating rod 32 is penetrated by the connecting rod 34 and is slidably connected to the connecting rod 34, a return spring 35 is fixed on the inner wall of the rotating rod 32, one end of the return spring 35 away from the rotating rod 32 is fixed on the left side of the connecting rod 34, the right side of the connecting rod 34 is rotatably installed inside the rotating nozzle 36, a cleaning rod 37 is fixed on the left side of the rotating nozzle 36, a transverse groove 38 and an annular groove 39 are formed on the surface of the spray pipe 2, the transverse groove 38 and the annular groove 39 are communicated with each other, a sliding rod 310 is inserted inside the transverse groove 38, and one end of the sliding rod 310 away from the spray pipe 2 is fixed to the cleaning rod 37. When the main body 1 of the spraying machine sprays the liquid medicine through the spray pipe 2, the liquid medicine impacts on the impeller 33 to drive the impeller 33 and the rotating rod 32 to rotate, the rotating rod 32 drives the connecting rod 34 to rotate, the liquid medicine impacts on the rotating nozzle 36, pushes the rotating nozzle 36 to move to the right, the rotating nozzle 36 drives the cleaning rod 37 to rotate together, and the cleaning rod 37 can clean the surface of the spray pipe 2 to prevent some sundries such as leaves from adhering to the surface of the spray pipe 2.

[0022] A opening component 4 is provided on the rotating nozzle 36. The opening component 4 includes a disc 41 which is penetrated by a connecting rod 34 and fixed to the connecting rod 34. An arc-shaped chute 42 is formed on the disc 41. A guiding groove 43 is formed on the inner side of the rotating nozzle 36. A baffle 44 is slidably installed on the inner side of the guiding groove 43. A fixing rod 45 is fixed to the left side of the baffle 44. The fixing rod 45 is inserted into the inner side of the arc-shaped chute 42. When the connecting rod 34 rotates, the connecting rod 34 drives the disc 41 to rotate together. Since the baffle 44 is limited by the guiding groove 43, the disc 41 can push the fixing rod 45 and the baffle 44 to move towards the side close to the center of the disc 41 through the arc-shaped chute 42 formed thereon.

[0023] Sector-shaped holes 5 are formed on both the disc 41 and the rotating nozzle 36 for the liquid medicine to pass through. The sector-shaped hole 5 on the rotating nozzle 36 is blocked by the baffle 44 in the initial state. When the liquid medicine impacts on the rotating nozzle 36, it first pushes the rotating nozzle 36 to move rightward. During this process, the connecting rod 34 drives the disc 41 to rotate. When it is controlled that the baffle 44 no longer blocks the sector-shaped hole 5 on the rotating nozzle 36, the liquid medicine can be sprayed through the sector-shaped hole 5 to spray the planted grains. At this time, the connecting rod 34 can drive the rotating nozzle 36 to rotate together through the disc 41 and the baffle 44.

[0024] Based on the above embodiments, when the medicine spraying machine body 1 sprays the liquid medicine through the spray pipe 2, the liquid medicine impacts on the impeller 33 to drive the impeller 33 and the rotating rod 32 to rotate. The rotating rod 32 drives the connecting rod 34 to rotate. The liquid medicine impacts on the rotating nozzle 36. Since the baffle 44 blocks the sector-shaped hole 5 on the rotating nozzle 36 at this time and the liquid medicine cannot pass through normally, the rotating nozzle 36 can be pushed to move rightward. During this process, the connecting rod 34 drives the disc 41 to rotate. Since the baffle 44 is limited by the guiding groove 43, the disc 41 can push the fixing rod 45 and the baffle 44 to move towards the side close to the center of the disc 41 through the arc-shaped chute 42 formed thereon. When it is controlled that the baffle 44 no longer blocks the sector-shaped hole 5 on the rotating nozzle 36, the liquid medicine can be sprayed through the sector-shaped hole 5 to spray the planted grains. At this time, the connecting rod 34 can drive the rotating nozzle 36 to rotate together through the disc 41 and the baffle 44.

[0025] When the rotating nozzle 36 rotates, the rotating nozzle 36 drives the cleaning rod 37 to rotate together, and the cleaning rod 37 can clean the surface of the spray pipe 2 to prevent some sundries such as leaves from adhering to the surface of the spray pipe 2.

[0026] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
