Description

Technical Field

[0001] The present application relates to the technical field of agricultural equipment, and in particular to an agricultural machine. Background Art

[0002] Agricultural machinery is a kind of agricultural equipment that can automatically perform agricultural farming. It usually consists of a head mounted with a mounting device of corresponding functions to perform corresponding operations. For example, when sowing, the seeder is mounted on the head. The seeder can realize mobile sowing under the drive of the head.

[0003] However, the current agricultural machinery of this type has a large size. Since the mechanized terraced farmland is usually a small plot, the terrain boundary of this target operation area has strong constraints and restrictions on the movement path of agricultural machinery. In other words, the application scope of most current agricultural machinery is based on factors such as the terrain of the operation area, and there are certain limitations. Utility Model Content

[0004] The purpose of the present application is to provide an agricultural machinery, which integrates operating mechanisms such as a tillage mechanism and a spraying mechanism on a vehicle body, thereby reducing the overall size of the agricultural machinery, and can design the overall size of the agricultural machinery to be smaller, so that it can be suitable for target operating areas of small fields such as terraced farmland suitable for mechanization, and ultimately can expand the scope of application of the agricultural machinery.

[0005] An agricultural machine provided in the present application includes: a vehicle body, a tillage mechanism and a spraying mechanism; the vehicle body has a head end and a tail end, and the head end faces the forward direction of the vehicle body; the tillage mechanism and the spraying mechanism are respectively arranged on the vehicle body; the tillage mechanism includes a tillage shovel, and the tillage shovel is located at the head end; the spraying mechanism includes a nozzle, and the nozzle is located at the tail end; the spraying mechanism is configured to spray a spray material to a target area; the tillage mechanism is configured to till the target area.

[0006] The above-mentioned agricultural machine reduces the overall size of the agricultural machine by integrating the tillage mechanism, the spraying mechanism and other operating mechanisms on the vehicle body. In addition, since the operating mechanism is integrated on the vehicle body, the overall size of the agricultural machine can be designed to be smaller, so that the agricultural machine provided by the present application can be applied to the target operating area of ​​small plots such as terraced cultivated land suitable for mechanization, and finally expands the scope of application of the agricultural machine.

[0007] Optionally, the tilling mechanism further includes a connecting assembly; one end of the connecting assembly is connected to the vehicle body; and the other end of the connecting assembly is detachably connected to the tilling shovel.

[0008] The above agricultural machine facilitates the separate replacement and maintenance of the tillage shovel through the detachable connection between the connecting assembly in the tillage mechanism and the tillage shovel, thereby enhancing the flexibility of the agricultural machine and reducing the maintenance cost of the agricultural machine.

[0009] Optionally, a through hole is provided at one end of the connecting assembly connected to the tilling shovel; the tilling shovel includes a shovel head, a shovel handle and a nut; wherein the maximum radial dimension of the nut is greater than the radial dimension of the through hole; one end of the shovel handle is connected to the shovel head, and the other end of the shovel handle is provided with a thread matching the nut; the other end of the shovel handle passes through the through hole, and the nut is threadedly connected to the other end of the shovel handle on both sides of the through hole.

[0010] The agricultural machine can adapt to more connecting components of different thicknesses and shapes by screwing the shovel handle and the connecting component in the tillage shovel through adjustment between the nut and the shovel handle. In addition, the screwing method makes it easier to disassemble and assemble the tillage shovel and the connecting component.

[0011] Optionally, the shovel head has a front end and a rear end; the direction of the front end is consistent with the direction of the front end of the vehicle body, and the direction of the rear end is consistent with the direction of the rear end of the vehicle body; the rear end is connected to the shovel handle; in the width direction parallel to the plane where the target area is located and perpendicular to the forward direction, the width of the front end is smaller than the width of the rear end; in the vertical direction perpendicular to the plane where the target area is located and the forward direction, the height of the front end is smaller than the height of the rear end.

[0012] The agricultural machine has a narrow front and wide rear shovel head, which reduces the resistance of the shovel head when entering the soil, thereby making it easier for the shovel head to enter the soil. It also makes it easier for the shovel head to cut the soil layer during the tillage project. In addition, the shovel head is designed to be high in the middle and low on both sides, making it easier to turn the soil layer.

[0013] Optionally, the number of the tilling shovels is at least two; the distribution direction of the tilling shovels is parallel to the plane where the target area is located, and is not parallel to the advancing direction; the through hole includes elongated holes, and the number of the elongated holes is greater than or equal to the number of the tilling shovels; the elongated holes have a length direction and a width direction; the length direction is parallel to the distribution direction of the tilling shovels, and the elongated holes greater than or equal to the number of the tilling shovels are arranged along the length direction; the size of the elongated holes in the length direction is greater than the diameter of the shovel handle, and the size of the elongated holes in the width direction matches the diameter of the shovel handle.

[0014] The above-mentioned agricultural machinery realizes the adjustable position of a single tilling shovel on the connecting component by designing the through hole as a long hole, so that the spacing between the tilling shovels can be achieved by adjusting the position of a single tilling shovel on the connecting component, thereby enabling the agricultural machinery to meet more tillage needs and improving the convenience of the agricultural machinery.

[0015] Optionally, the connecting assembly includes a lifting assembly; the lifting assembly is configured to drive the tilling shovel to approach or move away from the plane where the target area is located.

[0016] The agricultural machine adopts a lifting assembly as a specific connecting assembly to realize the lifting and lowering of the tillage shovel on the vehicle body. During the tillage process, the user can adjust the height of the tillage shovel according to the tillage depth and other requirements. In addition, when there is no need to till, the user can adjust the height of the tillage shovel to the highest level to reduce the obstruction of the tillage shovel to the vehicle body during driving. Finally, the convenience of the agricultural machine is improved.

[0017] Optionally, the lifting assembly includes a linear driving member and a swinging member; the driving member is arranged on the vehicle body; the swinging member is rotatably arranged on the vehicle body, and the rotation axis of the swinging member is located between its two ends; wherein the rotation axis is parallel to the plane where the target area is located; one end of the swinging member is rotatably connected to the output end of the driving member, and the other end of the swinging member is rotatably connected to the tillage shovel.

[0018] The above agricultural machine realizes the height adjustment of the tillage shovel through the connection and linkage of the linear drive member and the swing member. Compared with other connection components that can realize the height adjustment of the tillage shovel, this structure has a simpler structure and principle, thereby reducing the manufacturing and maintenance costs of the agricultural machine and improving the stability of the agricultural machine during operation.

[0019] Optionally, the direction of the nozzle is perpendicular to the plane where the target area is located.

[0020] The agricultural machinery, by aligning the direction of the nozzle perpendicular to the plane where the target area is located, can prevent the spray from drifting in the air to the greatest extent during the spraying process, thereby reducing waste and impact on the environment and personnel.

[0021] Optionally, the agricultural machinery also includes a driving mechanism; the driving mechanism includes a driving wheel, a first driven wheel, a second driven wheel and a transmission belt; the driving wheel, the first driven wheel and the second driven wheel are arranged on the side of the vehicle body; wherein the side is arranged in a direction parallel to the plane where the target area is located and perpendicular to the forward direction; the arrangement direction of the first driven wheel and the second driven wheel is parallel to the forward direction, the driving wheel, the first driven wheel and the second driven wheel are not colinear, and the driving wheel is located on the side of the first driven wheel away from the target area; the transmission belt surrounds and is sleeved on the driving wheel, the first driven wheel and the second driven wheel; the transmission belt is configured to partially contact the target area, and rotate under the drive of the driving wheel to make the vehicle body move forward or backward.

[0022] In the above-mentioned agricultural machinery, the driving wheel, the first driven wheel and the second driven wheel are respectively located at the three vertices of the triangle, and the driving wheel is located at a vertex above the triangle. Since the support of the vehicle body is usually provided by the part of the track between the first driven wheel and the second driven wheel located at the two vertices below the triangle, the position of the first driven wheel and the second driven wheel compared to the vehicle body determines the height of the entire agricultural machinery chassis. In addition, the driving wheel is located at a vertex above the triangle, so the position of the driving wheel compared to the vehicle body will not affect the height of the entire agricultural machinery chassis. Furthermore, the position setting of the driving wheel does not need to consider factors such as the height of the agricultural machinery chassis, and when determining the setting positions of the first driven wheel and the second driven wheel on the vehicle body according to the chassis height requirements, it will not be limited by the setting position of the driving wheel. That is, the setting positions of the driving wheel, the first driven wheel and the second driven wheel are more flexible.

[0023] Optionally, the driving mechanism also includes a connecting rod; the connecting rod is arranged on the side of the vehicle body; a first slide groove and a second slide groove are respectively arranged at both ends of the connecting rod; the axle of the first driven wheel can be slidably arranged in the first slide groove, and the axle of the second driven wheel can be slidably arranged in the second slide groove; the sliding direction of the first driven wheel and the sliding direction of the second driven wheel are respectively parallel to the plane where the side surface is located.

[0024] The agricultural machine, by making the positions of the first driven wheel and the second driven wheel on the connecting rod adjustable, realizes the adjustable spacing between the first driven wheel and the second driven wheel, that is, the perimeter of the triangle formed by the positions of the driving wheel, the first driven wheel, and the second driven wheel is adjustable. Before installing the transmission belt, the position of the first driven wheel and / or the second driven wheel on the connecting rod is adjusted to reduce the spacing between the first driven wheel and the second driven wheel, making the transmission belt easier to install; after the transmission belt is installed, the position of the first driven wheel and / or the second driven wheel on the connecting rod is adjusted to increase the spacing between the first driven wheel and the second driven wheel, making the support for the transmission belt more sufficient and improving the stability of the transmission belt after installation.

[0025] In summary, the agricultural machinery provided by the present application is integrated with the working mechanisms such as the tillage mechanism and the spraying mechanism on the vehicle body, thereby reducing the overall size of the agricultural machinery and ultimately expanding the scope of application of the agricultural machinery. The detachable connection between the connecting assembly and the tillage shovel in the tillage mechanism facilitates the separate replacement and maintenance of the tillage shovel. In addition, the flexibility of the agricultural machinery is enhanced and the maintenance cost of the agricultural machinery is reduced. The shovel head is narrow in front and wide in the back, which reduces the resistance when the shovel head enters the soil, thereby making it easier for the shovel head to enter the soil. And it makes it easier for the tillage shovel head to cut the soil layer during the tillage project. In addition, the shape design of the shovel head being high in the middle and low on both sides makes it easier to turn the soil layer. The spacing between the tillage shovels can be achieved by adjusting the position of a single tillage shovel on the connecting assembly, thereby enabling the agricultural machinery to meet more tillage needs and improving the convenience of the agricultural machinery. During the tillage process, the user can adjust the height of the tillage shovel according to the needs such as the tillage depth. In addition, when there is no need to till, the user can adjust the height of the tillage shovel to the highest to reduce the obstruction of the tillage shovel to the vehicle body during driving. Ultimately, the convenience of agricultural machinery is improved. By orienting the nozzle perpendicular to the plane of the target area, waste and impact on the environment and personnel are reduced. The positions of the first driven wheel and the second driven wheel on the connecting rod are adjustable, making the transmission belt easier to install and improving the stability of the transmission belt after installation.

[0038] Please refer to Figure 1 , Figure 1 It is a first stereoscopic diagram of the agricultural machinery 100 provided in the embodiment of the present application. The agricultural machinery 100 provided in the embodiment of the present application may include: a vehicle body 110, a tillage mechanism 120 and a spraying mechanism 130. The vehicle body 110 may have a head end and a tail end, and the head end may face the forward direction of the vehicle body 110. The tillage mechanism 120 and the spraying mechanism 130 are respectively arranged on the vehicle body 110. The tillage mechanism 120 may include a tillage shovel 121, and the tillage shovel 121 may be located at the head end. The spraying mechanism 130 may include a nozzle 131, and the nozzle 131 may be located at the tail end. The spraying mechanism 130 may be configured to spray the spraying material to the target area. The tillage mechanism 120 may be configured to till and shovel the target area.

[0039] The vehicle body 110 may be the most important part of the entire agricultural machine 100. In addition to the tillage mechanism 120 and the spraying mechanism 130, other operating mechanisms may also be arranged on it. In addition to the operating mechanism, the vehicle body 110 may also be provided with a driving mechanism 140, which may be a crawler type, a wheel type, etc. The vehicle body 110 may also be provided with an energy carrier that provides energy for the driving mechanism 140, such as a battery, a fuel tank, etc. A wireless communication antenna, an image acquisition component, a controller, etc. may also be arranged on the vehicle body 110. The controller may be configured to obtain the image acquired by the image acquisition component, and control the driving mechanism 140 to drive the vehicle body 110 according to the acquired image, so as to realize automatic driving of the vehicle body 110. The tillage mechanism 120 and the spraying mechanism 130 and other operating mechanisms may also be controlled to automatically operate according to the acquired image. The controller may also output the acquired image through the wireless communication antenna. For example: sending it to an electronic device held by a user so that the user can remotely follow up the operation of the agricultural machine 100.

[0040] The head end and the tail end of the vehicle body 110 can be a definition of a movable device in a popular understanding by those skilled in the art. The tillage shovel 121 in the tillage mechanism 120 can be connected to the vehicle body 110 through a corresponding connecting assembly. The tillage shovel 121 can be used for weeding, turning the soil, and plowing operations in the target area. The spraying mechanism 130 can also include a spraying material holding box. The spraying material holding box can be set on the vehicle body 110. The spray can be water, nutrient solution or agriculture, etc. The target area is usually the operating area where the agricultural machine 100 operates, and the target area can specifically be a farmland, a garden, a lawn or a crop base, etc.

[0041] In the above implementation process, the overall size of the agricultural machine 100 is reduced by integrating the tillage mechanism 120, the spraying mechanism 130 and other operating mechanisms on the vehicle body 110. In addition, since the operating mechanism is integrated on the vehicle body 110, the overall size of the agricultural machine 100 can be designed to be smaller, so that the agricultural machine 100 provided in the embodiment of the present application can be applied to the target operating area of ​​small plots such as terraced cultivated land suitable for mechanization, and finally expand the scope of application of the agricultural machine 100.

[0042] Please continue to refer to Figure 1 In some optional embodiments, the tillage mechanism 120 may further include a connection assembly. One end of the connection assembly may be connected to the vehicle body 110. The other end of the connection assembly may be detachably connected to the tillage shovel 121.

[0043] The connecting assembly can be a simple connecting rod 145, or a component composed of multiple parts that can achieve other functions besides connecting the tilling shovel 121 to the vehicle body 110. The detachable connection between the tilling shovel 121 and the other end of the connecting assembly can be a screw connection, a clamp connection, a riveted connection or a pin connection.

[0044] In the above implementation process, the detachable connection between the connecting assembly in the tillage mechanism 120 and the tillage shovel 121 facilitates the separate replacement and maintenance of the tillage shovel 121, thereby enhancing the flexibility of the agricultural machine 100 and reducing the maintenance cost of the agricultural machine 100.

[0045] Please combine Figure 1 Reference Figure 2 , Figure 2 It is a second stereoscopic diagram of the agricultural machinery 100 provided in an embodiment of the present application. In some optional embodiments, a through hole may be provided at one end of the connecting assembly connected to the tilling shovel 121. The tilling shovel 121 may include a shovel head 1211, a shovel handle 1212 and a nut 1213. Among them, the maximum radial dimension of the nut 1213 may be greater than the radial dimension of the through hole. One end of the shovel handle 1212 may be connected to the shovel head 1211, and the other end of the shovel handle 1212 may be provided with a thread matching the nut 1213. The other end of the shovel handle 1212 may pass through the through hole, and the nut 1213 may be threadedly connected to the other end of the shovel handle 1212 on both sides of the through hole.

[0046] The shovel handle 1212 may be a rod for connecting the shovel head 1211 to the connecting assembly. The radial dimension of the through hole may be the diameter of the through hole. The diameter of the through hole may be larger than the outer diameter of the shovel handle 1212; or it may match the outer diameter of the shovel handle 1212, and the inner wall of the through hole may be provided with an internal thread matching the thread provided on the shovel handle 1212.

[0047] The specific shape of the shovel head 1211 can be designed by those skilled in the art into a corresponding shape according to the specific operation requirements of the tillage mechanism 120. The embodiment of the present application does not impose any specific limitation on this.

[0048] In the above implementation process, the tillage shovel 121 can be adapted to more connecting components of different thicknesses and shapes by screwing the shovel handle 1212 and the connecting component in the tillage shovel 121, and adjusting the nut 1213 and the shovel handle 1212. In addition, the screwing method makes it easier to disassemble and assemble the tillage shovel 121 and the connecting component.

[0049] Please refer to Figure 3 and Figure 4 , Figure 3 This is a first stereoscopic view of the tillage shovel 121 in the agricultural machine 100 provided in the embodiment of the present application; Figure 4This is a second stereoscopic view of the tillage shovel 121 in the agricultural machinery 100 provided in the embodiment of the present application. In some optional embodiments, the shovel head 1211 may have a front end and a rear end. The orientation of the front end may be consistent with the orientation of the head end, and the orientation of the rear end may be consistent with the orientation of the tail end. The rear end may be connected to the shovel handle 1212. In the width direction parallel to the plane where the target area is located and perpendicular to the forward direction, the width of the front end may be smaller than the width of the rear end. In the vertical direction perpendicular to the plane where the target area is located and the forward direction, the height of the front end may be smaller than the height of the rear end.

[0050] That is, the shovel head 1211 may be a triangle, arrowhead, or other shape with a sharp front and wide rear. In addition, the shovel head 1211 may have wedge surfaces, convex curved surfaces, or concave curved surfaces on both sides of the center line that is collinear with the head end of the vehicle body 110 .

[0051] In the above implementation process, the shovel head 1211 is narrow in front and wide in the back, which reduces the resistance when the shovel head 1211 enters the soil, thereby making it easier for the shovel head 1211 to enter the soil. It also makes it easier for the shovel head 1211 to cut the soil layer during the tillage project. In addition, the shovel head 1211 is designed to be high in the middle and low on both sides, making it easier to turn the soil layer.

[0052] Please continue to refer to Figure 1 and Figure 2 In some optional embodiments, the number of tilling shovels 121 may be at least two. The distribution direction of the tilling shovels 121 may be parallel to the plane where the target area is located, and may not be parallel to the advancing direction. The through hole may include elongated holes, and the number of the elongated holes may be greater than or equal to the number of tilling shovels 121. The elongated holes may have a length direction and a width direction. The length direction may be parallel to the distribution direction of the tilling shovels 121, and the elongated holes greater than or equal to the number of the tilling shovels 121 are arranged along the length direction. The size of the elongated holes in the length direction may be greater than the diameter of the shovel handle 1212, and the size of the elongated holes in the width direction may match the diameter of the shovel handle 1212.

[0053] The number of the tillage shovels 121 may be two, three, four, etc. The distribution direction thereof may be specifically a direction perpendicular to the direction of the head end of the vehicle body 110 .

[0054] The elongated holes may be waist holes. As a preferred embodiment, the distribution direction of the elongated holes may be parallel to the distribution direction of the tillage shovels 121. When the number of the elongated holes is the same as the number of the tillage shovels 121, it means that each elongated hole can be installed with a tillage shovel 121; when the number of the elongated holes is greater than the number of the tillage shovels 121, it means that when all the tillage shovels 121 are installed in the elongated holes, there are still vacant elongated holes as alternatives.

[0055] When the shovel handle 1212 passes through the elongated hole and the nut 1213 is not yet tightened, the shovel handle 1212 can extend the length of the elongated hole and move in the elongated hole. Thus, the position of the shovel handle 1212 in the elongated hole can be adjusted. After the specific position of the shovel handle 1212 in the elongated hole is determined, the connection between the shovel handle 1212 and the connecting assembly can be tightened by rotating the nut 1213 on the shovel handle 1212.

[0056] During the above implementation process, by designing the through hole as a long hole, the position of a single tilling shovel 121 on the connecting component can be adjusted, so that the spacing between the tilling shovels 121 can be achieved by adjusting the position of a single tilling shovel 121 on the connecting component, thereby enabling the agricultural machinery 100 to meet more tillage needs and improving the convenience of the agricultural machinery 100.

[0057] Please continue to refer to Figure 1 and Figure 2 In some optional embodiments, the connection assembly may include a lifting assembly. The lifting assembly may be configured to drive the tilling shovel 121 to approach or move away from the plane where the target area is located.

[0058] The lifting assembly can be specifically lifted and lowered in a slidable manner, for example, the lifting assembly can include a guide rod disposed on the vehicle body 110 and a sliding member sleeved on the guide rod, and the sliding member is connected to the tillage shovel 121. In this way, the tillage shovel 121 can be lifted and lowered by sliding the sliding member on the guide rod. The guide rod can also be replaced by a guide rail. The lifting assembly can also be other structures known to those skilled in the art. The lifting assembly can also be the structure described in the subsequent embodiments of this application.

[0059] In the above implementation process, the lifting assembly is used as a specific connection assembly to realize the lifting and lowering of the tillage shovel 121 on the vehicle body 110. In the tillage process, the user can adjust the height of the tillage shovel 121 according to the tillage depth and other requirements. In addition, when there is no need to till, the user can adjust the height of the tillage shovel 121 to the highest level to reduce the obstruction of the tillage shovel 121 to the driving process of the vehicle body 110. Finally, the convenience of the agricultural machine 100 is improved.

[0060] Please continue to refer to Figure 1 and Figure 2In some optional embodiments, the lifting assembly may include a linear driving member 1222 and a swinging member 1223. The driving member may be disposed on the vehicle body 110. The swinging member 1223 may be rotatably disposed on the vehicle body 110, and the rotation axis of the swinging member 1223 may be located between its two ends. The rotation axis may be parallel to the plane where the target area is located. One end of the swinging member 1223 may be rotatably connected to the output end of the driving member, and the other end of the swinging member 1223 may be rotatably connected to the tilling shovel 121.

[0061] The linear drive member 1222 may be a push rod or a cylinder. The swing member 1223 is rotatably connected to the vehicle body 110 at the position between its two ends, so that when the swing member 1223 rotates around its rotation axis, the heights of its two ends change accordingly. This also causes the tillage shovel 121 connected to one end of the swing member 1223 to change in height.

[0062] In the above implementation process, the height of the tillage shovel 121 is adjustable through the connection and linkage between the linear drive member 1222 and the swing member 1223. Compared with other connection components that can achieve the height adjustment of the tillage shovel 121, this structure has a simpler structure and principle, thereby reducing the manufacturing and maintenance costs of the agricultural machine 100 and improving the stability of the agricultural machine 100 during operation.

[0063] Please continue to refer to Figure 1 and Figure 2 In some optional embodiments, the direction of the nozzle 131 can be perpendicular to the plane where the target area is located.

[0064] The nozzle 131 generally has a spraying port. In the embodiment of the present application, the direction of the spraying port may be perpendicular to the plane where the target area is located.

[0065] In the above implementation process, by aligning the direction of the nozzle 131 perpendicular to the plane where the target area is located, the agricultural machine 100 can avoid the spray material from drifting in the air to the greatest extent during the spraying process, thereby reducing waste and the impact on the environment and personnel.

[0066] Please continue to refer to Figure 1 and Figure 2In some optional embodiments, the agricultural machine 100 may further include a driving mechanism 140. The driving mechanism 140 may include a driving wheel 141, a first driven wheel 142, a second driven wheel 143, and a transmission belt 144. The driving wheel 141, the first driven wheel 142, and the second driven wheel 143 may be arranged on the side of the vehicle body 110. Among them, the side surface may be arranged in a direction parallel to the plane where the target area is located and perpendicular to the direction of advance. The arrangement direction of the first driven wheel 142 and the second driven wheel 143 may be parallel to the direction of advance, the driving wheel 141, the first driven wheel 142, and the second driven wheel 143 may not be colinear, and the driving wheel 141 may be located on the side of the first driven wheel 142 away from the target area. The transmission belt 144 may surround and be sleeved on the driving wheel 141, the first driven wheel 142, and the second driven wheel 143. The driving belt 144 may be configured to partially contact the target area and rotate under the driving of the driving wheel 141 to move the vehicle body 110 forward or backward.

[0067] The number of the driving mechanisms 140 may be two, and they may be respectively disposed on two sides of the vehicle body 110 .

[0068] In the embodiment of the present application, the driving wheel 141, the first driven wheel 142 and the second driven wheel 143 in the driving mechanism 140 can be located at the three vertices of a triangle respectively. Figure 1 and Figure 2 As shown, the first driven wheel 142 and the second driven wheel 143 may be located at two vertices below the triangle respectively, and the driving wheel 141 may be located at a vertex above the triangle.

[0069] The transmission belt 144 can be a track, such as a rubber track or a metal track.

[0070] In the above implementation process, the driving wheel 141, the first driven wheel 142 and the second driven wheel 143 are respectively located at the three vertices of the triangle, and the driving wheel 141 is arranged at a vertex above the triangle. Since the support of the vehicle body 110 is usually provided by the part of the crawler between the first driven wheel 142 and the second driven wheel 143 located at the two vertices below the triangle, the position of the first driven wheel 142 and the second driven wheel 143 compared to the vehicle body 110 determines the height of the chassis of the entire agricultural machine 100. In addition, the driving wheel 141 is located at a vertex above the triangle, so the position of the driving wheel 141 compared to the vehicle body 110 will not affect the height of the chassis of the entire agricultural machine 100. Furthermore, the position setting of the driving wheel 141 does not need to consider factors such as the height of the chassis of the agricultural machine 100, and when determining the setting positions of the first driven wheel 142 and the second driven wheel 143 on the vehicle body 110 according to the chassis height requirement, it will not be limited by the setting position of the driving wheel 141. That is, the arrangement positions of the driving wheel 141 , the first driven wheel 142 and the second driven wheel 143 are more flexible.

[0071] Please continue to refer to Figure 1 and Figure 2 In some optional embodiments, the driving mechanism 140 may further include a connecting rod 145. The connecting rod 145 may be disposed on the side of the vehicle body 110. A first slide groove 1451 and a second slide groove 1452 may be disposed at both ends of the connecting rod 145, respectively. The axle of the first driven wheel 142 may be slidably disposed in the first slide groove 1451, and the axle of the second driven wheel 143 may be slidably disposed in the second slide groove 1452. The sliding direction of the first driven wheel 142 and the sliding direction of the second driven wheel 143 may be parallel to the plane where the side surface is located, respectively.

[0072] That is to say, the positions of the first driven wheel 142 and the second driven wheel 143 on the connecting rod 145 are adjustable. Since the sliding direction of the first driven wheel 142 and the sliding direction of the second driven wheel 143 may not be parallel, the distance between the first driven wheel 142 and the second driven wheel 143 can be changed by adjusting the positions of the first driven wheel 142 and / or the second driven wheel 143 on the connecting rod 145.

[0073] On this basis, as a preferred embodiment, the sliding direction of the first driven wheel 142 and the sliding direction of the second driven wheel 143 can be parallel to the forward direction respectively.

[0074] In practical applications, before the transmission belt 144 is installed on the driving wheel 141, the first driven wheel 142, and the second driven wheel 143, the position of the first driven wheel 142 and / or the second driven wheel 143 on the connecting rod 145 can be adjusted to reduce the distance between the first driven wheel 142 and the second driven wheel 143, thereby facilitating the installation of the transmission belt 144. After the transmission belt 144 is installed, the position of the first driven wheel 142 and / or the second driven wheel 143 on the connecting rod 145 can be adjusted again to increase the distance between the first driven wheel 142 and the second driven wheel 143, thereby being able to more fully support the transmission belt 144, thereby improving the stability of the transmission belt 144 installed on the driving wheel 141, the first driven wheel 142, and the second driven wheel 143.

[0075] In the above implementation process, the first driven wheel 142 and the second driven wheel 143 are adjusted in position on the connecting rod 145, so that the distance between the first driven wheel 142 and the second driven wheel 143 is adjustable, that is, the perimeter of the triangle formed by the positions of the driving wheel 141, the first driven wheel 142, and the second driven wheel 143 is adjustable. Before installing the transmission belt 144, the position of the first driven wheel 142 and / or the second driven wheel 143 on the connecting rod 145 is adjusted to reduce the distance between the first driven wheel 142 and the second driven wheel 143, so that the transmission belt 144 is easier to install; after the transmission belt 144 is installed, the position of the first driven wheel 142 and / or the second driven wheel 143 on the connecting rod 145 is adjusted to increase the distance between the first driven wheel 142 and the second driven wheel 143, so that the support for the transmission belt 144 is more sufficient, and the stability of the transmission belt 144 after installation is improved.

[0076] In summary, the agricultural machine 100 provided in each embodiment of the present application is integrated with the working mechanisms such as the tillage mechanism 120 and the spraying mechanism 130 on the vehicle body 110, thereby reducing the overall size of the agricultural machine 100 and ultimately expanding the scope of application of the agricultural machine 100. The detachable connection between the connecting assembly in the tillage mechanism 120 and the tillage shovel 121 facilitates the separate replacement and maintenance of the tillage shovel 121. This enhances the flexibility of the agricultural machine 100 and reduces the maintenance cost of the agricultural machine 100. The shovel head 1211 is narrow in front and wide in the back, which reduces the resistance of the shovel head 1211 when entering the soil, thereby making it easier for the shovel head 1211 to enter the soil. And it makes it easier for the shovel head 1211 to cut the soil layer during the tillage project. In addition, the shape design of the shovel head 1211, which is high in the middle and low on both sides, makes it easier to turn over the soil layer. The spacing between the tillage shovels 121 can be achieved by adjusting the position of a single tillage shovel 121 on the connecting assembly, so that the agricultural machine 100 can meet more tillage needs and improve the convenience of the agricultural machine 100. During the tillage process, the user can adjust the height of the tillage shovel 121 according to the tillage depth and other requirements. In addition, when there is no need to till, the user can adjust the height of the tillage shovel 121 to the highest level to reduce the obstruction of the tillage shovel 121 to the vehicle body 110 during driving. Finally, the convenience of the agricultural machine 100 is improved. By making the direction of the nozzle 131 perpendicular to the plane where the target area is located, waste and the impact on the environment and personnel are reduced. Among them, vertical is not absolute vertical in the physical sense, but vertical in the engineering sense. For example, 90°±10° all belong to the definition of vertical in this application. The position of the first driven wheel 142 and the second driven wheel 143 on the connecting rod 145 is adjustable, which makes the transmission belt 144 easier to install and improves the stability of the transmission belt 144 after installation.

[0077] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
