Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a drive mechanism for a sprayer. Background Technology

[0002] A pesticide sprayer is an agricultural machine that disperses liquid pesticides. It is suitable for pest and disease control in forests, nurseries, orchards, and tea gardens; for field crops such as cotton, wheat, rice, and corn, as well as large-scale grasslands; and for pest and disease control in urban and suburban gardens, vegetable fields, and greenhouses. Pneumatic sprayers use a fan in conjunction with nozzles to deliver pesticides, achieving large-area, high-penetration spraying of crops and resulting in better spraying effects.

[0003] Pneumatic sprayers are typically mounted on a mobile vehicle, which then moves the sprayer and sprays the pesticides. Currently, pneumatic sprayers are equipped with separate drive mechanisms. This means that the sprayer itself has a drive mechanism to operate the blower and pesticide pump, while the mobile vehicle also has its own independent drive mechanism. These two drive mechanisms are independent of each other and cannot be linked.

[0004] Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] A drive mechanism for a pesticide sprayer, such as Figure 1 and Figure 2 It includes a medicine pump 11 and a fan 12 respectively located at the front and rear ends of the vehicle body 1, a gearbox 13 mounted on the vehicle body 1, and a traveling assembly 14 on the vehicle body 1 to enable the vehicle body 1 to move. The gearbox 13 drives the traveling assembly 14, the medicine pump 11 and the fan 12 to work through a transmission component. The medicine pump 11 is a plunger pump.

[0030] like Figure 1 and Figure 2 The output shaft of the gearbox 13 provides variable speed to the walking assembly 14, which facilitates the movement of the vehicle body 1. The gearbox 13 drives the medicine pump 11 and the fan 12 through the transmission components, so as to achieve the purpose of driving the fan 12 and the medicine pump 11 and the vehicle body 1 to move through a single power source, which simplifies the structure.

[0031] like Figure 1 and Figure 2 The vehicle body 1 includes several longitudinal and transverse support rods. The longitudinal support rods are distributed along the length of the sprayer, and the transverse support rods are distributed along the width of the sprayer. The longitudinal support rods are parallel to each other, and the transverse support rods are welded to the longitudinal support rods.

[0032] like Figure 2 and Figure 3 and Figure 6 and Figure 7 The gearbox 13 is located between the medicine pump 11 and the blower 12. The transmission component includes a drive shaft 132 rotatably mounted inside the gearbox 13. The drive shaft 132 is parallel to the horizontal shaft 131, which is the furthest point of the output shaft of the gearbox 13. The horizontal shaft 131 is the shaft inside the gearbox 13. The drive shaft 132 is provided with a drive gear 1321 that meshes with the drive gear 1311 on the horizontal shaft 131. The drive gear 1321 is slidably connected to the drive shaft 132. The gearbox 13 is provided with a drive component that drives the drive gear 1321 to slide back and forth along the drive shaft 132. When the drive component drives the drive gear 1321 to mesh with the drive gear 1311, it facilitates the horizontal shaft 131 inside the gearbox 13 to drive the drive shaft 132 to rotate, thereby driving the medicine pump 11 and the blower 12 to work. When the drive component drives the drive gear 1321 to move and make it misaligned with the drive gear 1311, the gearbox 13 does not drive the medicine pump 11 and the blower 12 to work, making it easier for the vehicle body 1 to travel to the side of the crops in the field.

[0033] like Figure 2 and Figure 3 and Figure 6 and Figure 7 Both ends of the drive shaft 132 extend into gearboxes 13, which are connected to the input shaft of the medicine pump 11 and the rotating shaft of the fan 12 via connector one and connector two, respectively. The output shaft of the gearbox 13 is connected to the traveling assembly 14. Thus, the gearbox 13 can drive the medicine pump 11, the fan 12, and the traveling assembly 14 to work. Connector one and connector two are respectively located at both ends of the drive shaft 132.

[0034] like Figure 6 and Figure 7 The connecting component includes a first sprocket 15 coaxially mounted on one end of the drive shaft 132 extending out of the outer wall of the gearbox 13, and a second sprocket 151 coaxially mounted on the input shaft of the medicine pump 11. The first sprocket 15 and the second sprocket 151 are connected by an annular chain 152. At this time, the input shaft of the medicine pump 11 is driven to rotate by the annular chain 152, thereby facilitating the operation of the medicine pump 11.

[0035] Alternatively, the connecting component includes a pulley 1 coaxially mounted on the drive shaft 132 extending out of the outer wall of the gearbox 13, and a pulley 2 coaxially mounted on the input shaft of the medicine pump 11. The pulley 1 and pulley 2 are connected by an annular belt 1 (not shown in the figure). In this case, the annular belt 1 drives the input shaft of the medicine pump 11 to rotate, thereby facilitating the operation of the medicine pump 11.

[0036] like Figure 3 and Figure 4The second connecting component includes a universal joint 153 located at one end of the drive shaft 132 extending out of the outer wall of the gearbox 13. A transmission shaft 154 is located at the end of the universal joint 153 away from the drive shaft 132. A second universal joint 155 is located at the end of the transmission shaft 154 away from the first universal joint 153. A speed increaser 156 is connected to the end of the second universal joint 155 away from the transmission shaft 154; that is, one end of the second universal joint 155 is connected to the input shaft of the speed increaser 156. The shaft of the blower 12 is mounted on the output shaft of the speed increaser 156. A mounting plate 16 for mounting the speed increaser 156 is provided on the vehicle body 1. The mounting plate 16 is located on one side of the longitudinal support rod. At this time, the transmission shaft 154 passes through each transverse support rod and connects to the input shaft of the speed increaser 156. The blower 12 is located on the side of the mounting plate 16 away from the speed increaser 156.

[0037] like Figure 6 and Figure 7 The driving component includes a movable rod 17 passing through the gearbox 13. Both ends of the movable rod 17 extend out of both ends of the gearbox 13. A movable block 171 is fixedly mounted on the movable rod 17. Movable plates 172 located on both sides of the drive gear 1321 are mounted on the movable block 171. There is a gap between the movable plate 172 and the outer wall of the drive shaft 132 to reduce friction between the movable plate 172 and the drive shaft 132 when the movable plate 172 drives the drive gear 1321 to move. A rotating rod 173 is rotatably connected to the outer wall of the gearbox 13. A lever 174 is fixedly mounted on the rotating rod 173. A sliding plate 175 is provided at one end of the movable rod 17 that extends out of the outer wall of the gearbox 13. Vertically distributed grooves 176 are opened on the sliding plate 175. Both the upper and lower ends of the grooves 176 extend out of the upper and lower ends of the sliding plate 175. The grooves 176 make the sliding plate 175 a U-shaped plate. A circular plate that slides in the groove 176 is provided at the end of the lever 174 away from the rotating rod 173.

[0038] like Figure 6 and Figure 7 When the user rotates the lever 173, the lever 173 drives the lever 174 to rotate around the central axis of the lever 173. This causes the circular plate to move within the slide groove 176, pushing the moving rod 17 to reciprocate within the gearbox 13, so that the drive gear 1321 and the driving gear 1311 mesh and disengage as needed.

[0039] The rotation of the rotating rod 173 is driven by the user. The rotation of the rotating rod 173 can be restricted by setting a clamping plate (not shown in the figure) on the vehicle body 1. The clamping plate has two grooves. A sleeve is slidably connected to the outer wall of the rotating rod 173 along the length of the rotating rod 173. The inner wall of the sleeve is provided with a slider that slides on the outer wall of the rotating rod 173. The outer wall of the rotating rod 173 has a limiting groove distributed along the length of the rotating rod 173. The slider is slidably connected in the limiting groove. A clamping rod is provided on the outer wall of the sleeve. The user drives the clamping rod to rotate, which in turn drives the sleeve to rotate, which in turn drives the rotating rod 173 to rotate. When the rotating rod 173 rotates to the desired position, the sleeve is moved so that the clamping rod enters one of the grooves, thereby restricting the rotation of the rotating rod 173. At this time, the drive gear 1321 and the drive gear 1311 separate as needed. The other groove is for the clamping rod to enter when the rotating rod 173 rotates to the point where the drive gear 1321 and the drive gear 1311 mesh. A seat is fixed on the vehicle body 1 above the medicine pump 11 by a support rod, and the lever is located on one side of the seat.

[0040] like Figure 3 and Figure 4 The walking assembly 14 includes a universal joint 18 mounted on the output shaft of the gearbox 13. A rear axle 181 is mounted on the vehicle body 1, with drive tires 182 rotatably connected to both ends of the rear axle 181. A transmission rod 184 is located at the end of the universal joint 18 furthest from the output shaft of the gearbox 13, and a universal joint 185 connected to the transmission rod 184 is mounted on the rear axle 181. The output shaft of the gearbox 13 drives the rear axle 181 as a drive axle via the universal joint 18, transmission rod 184, and universal joint 185, thereby rotating the two drive tires 182. At this time, a driven tire 183 is rotatably connected to the front end of the seat on the vehicle body 1. The two drive tires 182 and one driven tire 183 cause the vehicle body 1 to move.

[0041] like Figure 4 and Figure 5 The vehicle body 1 is equipped with a support frame 19, which is an inverted U-shaped plate covering the gearbox 13. An engine 191 is mounted on the support frame 19. Both the output shaft of the engine 191 and the input shaft of the gearbox 13 are equipped with pulleys 192, which are connected by an annular belt 193. The pulleys 192 on the engine 191 drive the pulleys 192 on the input shaft of the gearbox 13 to rotate via the annular belt 193. At this time, the engine 191 provides power to the gearbox 13, facilitating the operation of the gearbox 13's input shaft.

[0042] like Figure 1The medicine tank 194 is installed on the vehicle body 1 and the medicine delivery pipe is connected so that the medicine delivery pipe connects the medicine pump 11 to the medicine tank 194. The output pipe of the medicine pump 11 delivers the medicine liquid to the mounting plate 16. The engine 191 drives the fan 12 and the medicine pump 11 to work. The medicine liquid in the medicine tank 194 is delivered to the spray nozzles set on each mounting plate 16 through the output pipe and atomized and sprayed out. The wind blown by the fan 12 blows the atomized droplets in all directions to achieve uniform spraying in all directions in the field.

[0043] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
