Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an agricultural base fertilizer spraying device. Background Art

[0002] Agricultural base fertilizer spraying device is an important agricultural equipment used in modern agriculture to evenly spray base fertilizer on farmland. The spraying device will spray the base fertilizer evenly on the farmland in the form of mist, droplets or particles through the nozzle, thereby effectively improving the yield and quality of crops, reducing production costs and reducing pollution.

[0003] When using a base fertilizer spraying device, you need to select a specific nozzle and connect the nozzle to the discharge pipe. The nozzle is generally fixed to the discharge pipe through a thread. In the process of using the nozzle to spray the base fertilizer, the nozzle may rotate relative to the discharge pipe under the action of external force, which may cause the nozzle and the discharge pipe to separate, causing the base fertilizer to leak. Utility Model Content

[0004] The utility model is an agricultural base fertilizer spraying device proposed to solve the problem that when using a nozzle to spray base fertilizer, the nozzle may rotate relative to the discharge pipe under the action of external force, which may cause the nozzle and the discharge pipe to separate and cause the base fertilizer to leak.

[0006] The effect achieved by the above components is: by setting two clamping plates, under the action of two threaded rods, the threaded rods are rotated, and the threaded rods will expand and contract on the inner wall of the side plate. During the expansion and contraction process, the threaded rods will drive the clamping plates to move synchronously until the two clamping plates completely clamp the connecting pipe, thereby fixing the threaded pipe and the connecting pipe, and then fixing the nozzle and the discharge pipe, which is beneficial to prevent the nozzle and the discharge pipe from detaching and preventing the base fertilizer from leaking.

[0008] The effect achieved by the above components is: by setting the slider and the slide groove, when the splint moves under the action of the threaded rod, the splint will drive the slider to slide synchronously on the inner wall of the slide groove, which can limit the splint.

[0009] Preferably, the outer surface of the threaded rod is threadedly connected with a nut, and the nut is arranged between the clamping plate and the side plate.

[0010] The effect achieved by the above components is: by setting a nut and rotating the nut so that one side of the nut abuts against one side of the side plate, one end of the threaded rod can be limited, which is helpful to prevent the two clamping plates from loosening the clamping of the connecting pipe.

[0012] The effect achieved by the above components is: by setting the operating block, rotating the operating block can drive the threaded rod to rotate, and at the same time, the outer surface of the operating block is provided with a protrusion, which can effectively increase the friction force of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0013] Preferably, the adjacent sides of the two clamping plates are both fixedly connected with a rubber plate, and one side of the rubber plate is arc-shaped.

[0014] The effect achieved by the above components is: by setting the rubber plate, one side of the clamping plate can be replaced to abut against the outer surface of the connecting pipe, and the friction between the rubber plate and the connecting pipe is increased, so that the two clamping plates can fix the connecting pipe and the threaded pipe more firmly.

[0015] Preferably, the anti-slip device comprises a rubber sleeve, which is provided on the outer surface of the handle, and grooves are evenly formed on the outer surface of the rubber sleeve.

[0016] The effect achieved by the above components is that by providing the rubber sleeve with grooves, the friction force on the outer surface of the handle can be increased, so that it has an anti-slip effect when holding the handle to operate the nozzle.

[0017] Preferably, a clamping strip is fixedly connected to the inner wall of the rubber sleeve, a clamping slot is provided on the outer surface of the handle, and the outer surface of the clamping strip is inserted into the inner wall of the clamping slot.

[0018] The effect achieved by the above components is: by providing the card strip and the card slot, the card slot can limit the rubber sleeve connected to the card strip, which is helpful to prevent the rubber sleeve from rotating on the outer surface of the handle when holding the handle.

[0019] Preferably, one end of the handle is fixedly connected to a stopper, one side of the stopper abuts against one end of the rubber sleeve, and the other end of the handle is sleeved with a clamping sleeve, the inner wall of the clamping sleeve is inserted with a bolt, and the outer surface of the bolt is threadedly inserted into the inner wall of the handle.

[0020] The effect achieved by the above components is: by setting the clamping sleeve, the clamping sleeve is set on one end of the handle, so that the two ends of the rubber sleeve are respectively abutted against the stopper and one side of the clamping sleeve, and then the bolt is inserted into the inner wall of the clamping sleeve, and the bolt is rotated so that the bolt enters the inner wall of the handle. The clamping sleeve can fix the rubber sleeve and the handle, which is helpful to prevent the rubber sleeve from falling off the handle.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] In the utility model, two clamping plates are provided. Under the action of two threaded rods, the threaded rods can drive the clamping plates to move synchronously until the two clamping plates completely clamp the connecting pipe. This can fix the threaded pipe and the connecting pipe, and then fix the nozzle and the discharge pipe, which is beneficial to prevent the nozzle and the discharge pipe from detaching and preventing the base fertilizer from leaking.
