Technical Field

[0001] The utility model relates to the technical field of farming equipment, in particular to a medicine spraying device for newly added cultivated land treatment. Background Technique

[0002] Due to the intrusion of industrial waste or agricultural chemicals, the soil will deteriorate and the land production potential will decline. It can be prevented and controlled by applying inhibitors or increasing organic fertilizers. In the prior art, most of the devices for applying inhibitors in the pollution control of cultivated land have relatively simple structures and can only spray medicines in a straight line or arc-shaped area, resulting in a limited spraying range and low working efficiency. Therefore, a medicine spraying device for newly added cultivated land treatment is proposed to solve the above problems. Content of the Utility Model

A transmission mechanism is arranged on the transmission shaft and the transmission direction is changed through the transmission mechanism to be connected with the spray head, so that the spray head moves periodically synchronously with the rotation of the walking wheels, changing the spraying area.

[0005] Further, the transmission mechanism includes a second bevel gear. The second bevel gear is arranged on the transmission shaft. A steering pipe communicating with the inside of the machine body is rotatably connected to the upper end of the machine body. A first bevel gear is sleeved on the outer periphery of the steering pipe. The first bevel gear and the second bevel gear are meshed, so that when the walking wheels rotate, the steering pipe is synchronously driven to rotate. Several spray heads are arranged on the outer periphery of the steering pipe.

[0006] Further, two sector gears are rotatably arranged at the upper end of the machine body. The spray head is fixed to the toothless end of the sector gear. The second bevel gear is arranged on the transmission shaft. A reciprocating lead screw is rotatably arranged at the upper end of the machine body. A transmission bevel gear meshing with the second bevel gear is fixed on the reciprocating lead screw. A nut adapted to the reciprocating lead screw is threadedly connected to the reciprocating lead screw. Tooth-shaped structures are arranged on the left and right sides of the nut to form racks. The two sides of the racks are respectively meshed with the sector gears, so that the spray heads on the toothless ends of the sector gears make reciprocating pendulum motions along with the movement of the racks.

[0007] Further, a flexible extension pipe communicating with the inside of the machine body is arranged at the upper end of the machine body. The extension pipe is communicated with the spray head.

[0008] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0009] The medicine spraying device for newly added cultivated land treatment connects the walking wheels and the spray heads through a transmission mechanism to form a synchronous transmission cooperation.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0015] Please refer to Figures 1 - 3 , a medicine spraying device for newly added cultivated land treatment in the present application includes a machine body 1. A walking wheel 11 is rotatably provided at the lower end of the machine body 1, and a spray head 15 is provided at the upper end of the machine body 1. It further includes a transmission belt 2. The spray head 15 extends to the outside of the machine body 1. The walking wheel 11 is connected to a transmission shaft 3 through the transmission belt 2. A transmission mechanism is provided on the transmission shaft 3, and the transmission direction is changed through the transmission mechanism to be connected to the spray head 15, so that the spray head 15 moves synchronously and periodically with the rotation of the walking wheel 11, changing the spraying area.

[0016] Usually, the medicine spraying device is that a person holds the spray head 15 by hand and carries a medicine box on the back for spraying medicine, or a medicine spraying vehicle is used for spraying medicine. However, the walking mechanism and the medicine spraying mechanism of the medicine spraying vehicle are not related in design, and the structure needs to be streamlined. In order to streamline the structure in the present application, the walking wheel 11 and the transmission shaft 3 are synchronously connected through the setting of the transmission belt 2, and then the transmission shaft 3 and the spray head 15 are connected through the transmission mechanism to form a synchronous transmission cooperation. When the machine is stationary, the spray head 15 does not need to be additionally controlled. Since the walking wheel 11 stops rotating, the spray head 15 also remains stationary. Once the machine body 1 starts to move, the spray head 15 begins to change the spraying angle following the walking wheel 11, changing the spraying area. The above solution enables the spray head 15 to change the spraying area when the walking wheel 11 drives the machine body 1 to move, realizing the utility of spraying medicine while the device is moving, and changing and increasing the spraying area of the medicine spraying, improving work efficiency.

[0017] In this application, the transmission mechanism can adopt multiple embodiments. This application provides two preferred embodiments, and the specific structures are as follows:

[0018] Embodiment 1

[0019] The transmission mechanism includes bevel gear two 31. Bevel gear two 31 is provided on the transmission shaft 3. The upper end of the machine body 1 is rotatably connected with a steering pipe 12 that communicates with the inside of the machine body 1. A bevel gear one 13 is sleeved on the outer periphery of the steering pipe 12. Bevel gear one 13 and bevel gear two 31 are meshed, so that when the traveling wheel 11 rotates, the steering pipe 12 is synchronously driven to rotate accordingly. A plurality of nozzles 15 are provided on the outer periphery of the steering pipe 12.

[0020] In this embodiment, bevel gear two 31 on the transmission shaft 3 rotates with the traveling wheel 11. The machine body 1 is rotatably provided with a steering pipe 12 that communicates with the medicine inside the machine body 1, and a bevel gear one 13 is sleeved on it at the same time. When the two bevel gears are meshed, the traveling wheel 11 and the steering pipe 12 form a synchronous drive. A rigid extension pipe 14 is connected to the steering pipe 12 and is connected to the nozzle 15 through the extension pipe 14. When the traveling wheel 11 rotates, it drives the steering pipe 12 and the nozzle 15 to continuously rotate, changing and increasing the medicine spraying range. It is worth mentioning that since the nozzle 15 sprays medicine in a 360-degree rotation, this embodiment is not suitable for manual cart spraying. It is more suitable for pre-laying tracks in cultivated land, rolling the traveling wheels 11 of the cart in the tracks, and automatically controlling the cart to spray medicine through a controller;

[0021] The steering pipe 12 is an existing technology in this field, including but not limited to the technical solutions disclosed in the Chinese patent with the publication number CN217363730U, and will not be elaborated here.

[0022] Embodiment 2

[0023] Two sector gears 35 are rotatably provided at the upper end of the machine body 1. The nozzle 15 is fixed to the toothless end of the sector gear 35. Bevel gear two 31 is provided on the transmission shaft 3. A reciprocating lead screw 33 is rotatably provided at the upper end of the machine body 1. A nut adapted to it is threadedly connected to the reciprocating lead screw 33. Tooth-like structures are provided on the left and right sides of the nut to form a rack 34. The two sides of the rack 34 are respectively meshed with the sector gears 35, so that the nozzle 15 on the toothless end of the sector gear 35 makes a reciprocating pendulum movement as the rack 34 moves.

[0024] In order to reduce the construction cost and usage cost, the present application also provides an embodiment that is more suitable for manual carts to apply pesticides to cultivated land. In this embodiment, a bracket is fixedly arranged at the upper end of the machine body 1, and a reciprocating lead screw 33 is rotatably connected between the brackets. A nut is threadedly connected to the reciprocating lead screw 33 in a matching manner. A guide rail (not shown in the figure) is also arranged on the bracket, and the guide rail is in contact with the nut to restrict the rotational tendency of the nut. When the reciprocating lead screw 33 rotates, the nut converts the rotational motion of the reciprocating lead screw 33 into its own reciprocating linear motion. The transmission bevel gear 32 on the reciprocating lead screw 33 meshes with the bevel gear two 31, so that when the traveling wheel 11 rotates, the reciprocating lead screw 33 continuously rotates accordingly. In this way, the toothed structures on both sides of the nut will reciprocally push the sector gear 35, and the end of the sector gear 35 lacking teeth will drive the nozzle 15 to reciprocate on both sides of the machine body 1. The device applies pesticides in the pendulum area of the nozzle 15. In this way, the user can push or pull the cart at the front end or the rear end of the machine body 1, so that the cart for applying pesticides moves, and the area where pesticides are applied will not cover the position where the personnel are located. In order to keep the nozzle outside the machine body and avoid wasting pesticides on the machine body, in this embodiment, the nozzle is connected to the end of the sector gear lacking teeth through a connecting rod 36.

[0025] Further, a flexible extension tube 14 communicating with the inside of the machine body 1 is provided at the upper end of the machine body 1, and the extension tube 14 is communicated with the nozzle 15.

[0026] In this embodiment, by providing a flexible extension tube 14 at the upper end of the machine body 1, one end of the extension tube 14 communicates with the pesticide inside the machine body 1, and the other end is communicated with the nozzle 15, so that the flexible extension tube 14 communicates the pesticide for the nozzle 15 and also ensures that the nozzle 15 can swing normally without interference.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
