Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment, particularly the frame of a sprayer. Background Technology

[0002] In existing designs of self-propelled boom sprayers, there is a common problem of unreasonable load distribution, resulting in uneven load distribution between the front and rear of the machine. This can easily lead to accidents such as tipping or tilting forward and deformation of the frame, which increases operational risks, especially when operating in complex terrain. At the same time, the problem of insecurely fixing the pesticide tank is also quite prominent. For example, the utility model patent CN207885535U discloses a cart-type motorized sprayer frame adjustment mechanism that lacks effective longitudinal limiting measures for the pesticide tank, causing the tank to easily slide longitudinally during operation. This not only affects the uniform spraying of the pesticide but may also create safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide a sprayer frame that solves the problems of poor frame stability and lack of longitudinal restraint for the medicine tank in the prior art. It improves the frame stability while effectively restraining the medicine tank longitudinally.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a sprayer frame, including a frame body, wherein the frame body is provided with an engine mounting position, a gearbox mounting position and a medicine tank mounting position in a longitudinal direction from front to back. The medicine tank mounting position includes mounting plates located on the left and right sides of the frame body and protruding vertically, and a connecting beam for connecting the mounting plates on both sides. The mounting plates, the connecting beam and the gearbox work together to restrict the longitudinal movement of the medicine tank located at the medicine tank mounting position.

[0005] After adopting the above technical solution, this utility model has the following advantages: By sequentially setting the engine mounting position, gearbox mounting position, and medicine tank mounting position on the frame body, the layout of each component is more reasonable, thereby achieving a more reasonable distribution of the front and rear loads of the entire machine and minimizing the risk of tipping or tilting accidents caused by uneven loads. This is particularly beneficial for improving operational safety and stability when operating in complex terrain. Secondly, the medicine tank mounting position includes vertically protruding mounting plates located on the left and right sides of the frame body, as well as connecting beams for connecting the mounting plates on both sides. This not only enhances the strength of the entire structure but also ensures that the force on the medicine tank during operation can be directly transmitted to the longitudinal beams, improving the overall structural stability and reliability. Furthermore, the combined action of the vertically protruding mounting plates on both sides of the frame body, the connecting beams, and the gearbox effectively restricts the longitudinal movement of the medicine tank, solving the problem of insecure medicine tank fixation in existing technologies. This minimizes the risk of the medicine tank sliding during operation, reduces the impact on the uniform spraying of the medicine, and significantly reduces safety hazards.

[0006] Furthermore, the frame body includes two longitudinal beams arranged side by side, and two mounting plates are arranged side by side on each longitudinal beam, with a connecting structure connecting the two mounting plates.

[0007] Using the aforementioned technical solution, the two parallel longitudinal beams can provide a more stable foundation support for the sprayer frame. Compared with a single longitudinal beam, they can better distribute and bear the weight from the upper medicine tank and other components, improve the overall load-bearing capacity of the sprayer frame, and reduce the possibility of deformation or damage to the sprayer frame due to uneven stress. Secondly, two mounting plates are arranged side by side on each longitudinal beam, which further enhances the strength of the local structure and can provide multiple limiting points for the medicine tank. The connection structure between the two mounting plates can work together with the mounting plates to further restrict the movement of the medicine tank.

[0008] Furthermore, the connection structure includes a first connecting plate located at the bottom of the mounting plate and a second connecting plate located at the top of the mounting plate. The first connecting plate is used for mounting the rear axle of the vehicle frame. The first connecting plate, the second connecting plate, and the mounting plate together form an installation channel for inserting the longitudinal beam.

[0009] Using the aforementioned technical solution, the first connecting plate is located at the bottom of the mounting plate, while the second connecting part is located at the top of the mounting plate. The double support design greatly enhances the rigidity and stability of the mounting plate, making the entire sprayer frame structure more robust. Through the close cooperation between the first and second connecting plates and the longitudinal beams, the load is ensured to be evenly distributed on the sprayer frame as much as possible, avoiding deformation or damage caused by local stress concentration. The first connecting plate is not only used to fix the mounting plate, but also for the rear axle installation of the frame, reducing the cost and space of designing a separate rear axle installation component, making the sprayer frame more compact.

[0010] Furthermore, the end of the first connecting plate extends beyond the edge of the mounting plate.

[0011] By adopting the aforementioned technical solution, the end of the first connecting plate extends beyond the edge of the mounting plate, increasing the contact area with the longitudinal beam, thereby enhancing the rigidity and load-bearing capacity of the entire structure.

[0012] Furthermore, the mounting plate includes a first mounting portion extending vertically along the frame body, and the connecting beam includes a limiting beam connecting the two first mounting portions, with the medicine box longitudinally defined between the limiting beam and the gearbox.

[0013] Through the above technical solution, the connecting beam is connected between the first mounting parts on both sides, forming a stable frame structure. This frame structure can effectively enhance the structural strength and rigidity of the frame body in the corresponding area, improve the support capacity of the entire frame body for each component, and enable it to better withstand various stresses and impacts generated during the movement of the sprayer frame. By longitudinally limiting the medicine tank between the limiting beam and the gearbox, the installation position of the medicine tank can be determined more accurately, and longitudinal displacement of the medicine tank during the movement of the sprayer frame can be prevented as much as possible. This ensures that the medicine tank is always in the designed installation position, thereby ensuring the stability and reliability of the entire sprayer frame.

[0014] Furthermore, the mounting plate also includes a second mounting portion extending longitudinally along the frame body, and the connecting crossbeam also includes a supporting crossbeam connecting the two second mounting portions, with the medicine box supported on the supporting crossbeam.

[0015] Through the above technical solution, the support beam provides direct and stable support for the medicine tank, ensuring that the medicine tank remains in the correct position as much as possible during vehicle operation, thereby minimizing shaking or displacement due to unstable support. Since the support beam connects the second mounting parts on both sides, it distributes the weight of the medicine tank more evenly across the frame, minimizing excessive local pressure. The second mounting parts extending longitudinally along the frame form a robust longitudinal support structure with the support beam connecting the second mounting parts on both sides, further enhancing the structural strength of the frame. Compared to unidirectional support, this structure can better withstand the weight of the medicine tank itself and the longitudinal forces generated during the movement of the sprayer frame, such as inertial forces during acceleration and deceleration, making the medicine tank installation more stable and reducing the possibility of structural deformation or loosening due to longitudinal forces.

[0016] Furthermore, it also includes a reinforcing part, which is connected between the first mounting part and the second mounting part, and the reinforcing part, the first mounting part and the second mounting part are integrally formed.

[0017] Through the above technical solution, the reinforcement effectively increases the connection strength between the first mounting part and the second mounting part, enabling the entire mounting plate to better disperse stress when subjected to external forces, reducing local stress concentration, thereby significantly improving the overall strength and load-bearing capacity of the mounting plate, ensuring that it can stably support components such as the medicine tank under working conditions such as sprayer frame. The one-piece molded structure ensures that there are as few connection gaps or weak points as possible between the reinforcement, the first mounting part and the second mounting part, resulting in stronger structural integrity and stability.

[0018] Furthermore, the frame body includes two longitudinal beams arranged side by side, and the gearbox mounting position includes gearbox mounting brackets located on each longitudinal beam. The gearbox mounting brackets on the two longitudinal beams extend symmetrically and towards each other and are spaced apart.

[0019] The above technical solution increases the rigidity and load-bearing capacity of the overall frame by setting two parallel longitudinal beams on the frame body. The gearbox mounting brackets extend symmetrically and in opposite directions and are spaced apart, providing multi-point support, effectively preventing the gearbox from shifting or loosening during operation, and also helping to distribute the weight of the gearbox evenly on the two longitudinal beams, avoiding local stress concentration.

[0020] Furthermore, the frame body includes two longitudinal beams arranged side by side, and a reinforcing crossbeam connecting the two longitudinal beams is provided between the gearbox mounting position and the medicine box mounting position.

[0021] The above technical solution involves installing a reinforcing crossbeam connecting the two longitudinal beams between the gearbox mounting position and the medicine tank mounting position. This provides additional lateral support, greatly enhancing the lateral rigidity of the sprayer frame and increasing its load-bearing capacity. The load can be distributed more evenly on the two longitudinal beams, avoiding local stress concentration and improving the overall stability and reliability of the equipment.

[0022] Furthermore, the frame body includes two longitudinal beams arranged side by side, and the frame body is also provided with a front axle mounting bracket for mounting the front axle of the frame. The engine mounting position includes an engine mounting bracket located on each longitudinal beam and at least part of the front axle mounting bracket. The engine mounting brackets on the two longitudinal beams extend symmetrically and towards each other and are spaced apart. The front axle mounting bracket connects the two longitudinal beams.

[0023] Through the above technical solution, two parallel longitudinal beams provide basic support for the sprayer frame, while the engine mounting brackets are located on each longitudinal beam, extending symmetrically towards each other and spaced apart, further enhancing the lateral rigidity of the front end of the sprayer frame. This makes the entire sprayer frame a stable structural system. The front axle mounting bracket is not only used for the installation of the front axle, but can also be used at least partially for the installation of the engine, avoiding the need for a separate and complex mounting structure for the engine. This greatly saves space at the front end of the sprayer frame. This compact design makes the layout of the sprayer frame more reasonable, allowing the engine load to be transferred to the longitudinal beams through the engine mounting brackets. Then, the longitudinal beams and the front axle mounting brackets connecting the longitudinal beams evenly distribute the force to the entire sprayer frame. The reasonable force transmission path effectively reduces stress concentration, improves the stability of the sprayer frame under various working conditions, and ensures the safety of the sprayer during operation.

[0035] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0036] like Figures 1 to 4 As shown, this utility model provides a sprayer frame, including a frame body 10. The frame body 10 has an engine mounting position 11, a gearbox mounting position 12 and a medicine tank mounting position 13 arranged in the longitudinal direction from front to back. The medicine tank mounting position 13 includes mounting plates 131 located on the left and right sides of the frame body 10 and protruding vertically, and a connecting beam 132 for connecting the mounting plates 131 on both sides. The mounting plates 131, the connecting beam 132 and the gearbox work together to restrict the longitudinal movement of the medicine tank located on the medicine tank mounting position 13.

[0037] By sequentially arranging the engine mounting position 11, gearbox mounting position 12, and medicine tank mounting position 13 on the frame body 10, the layout of each component is more reasonable, thereby achieving a more rational distribution of the front and rear loads of the entire machine and minimizing the risk of tipping or tilting accidents caused by uneven loads. This is particularly beneficial for improving operational safety and stability when operating in complex terrain. Secondly, the medicine tank mounting position 13 includes vertically protruding mounting plates 131 located on the left and right sides of the frame body 10, and connecting beams 132 for connecting the mounting plates 131 on both sides. This not only enhances the strength of the entire structure but also ensures that the force on the medicine tank during operation can be directly transmitted to the longitudinal beams 101, improving the overall stability and reliability of the structure. In addition, the gearbox is located on one side of the medicine box, and the mounting plate 131 and the connecting beam 132 are on the other side of the medicine box. Through the combined action of the mounting plate 131, the connecting beam 132 and the gearbox, the longitudinal movement of the medicine box can be effectively restricted, which solves the problem of the medicine box not being securely fixed in the prior art. It avoids the medicine box from sliding during operation as much as possible, reduces the impact on the uniform spraying of the medicine, and greatly reduces safety hazards.

[0038] The design of a single longitudinal beam 101 cannot provide sufficient lateral support, resulting in poor rigidity and load-bearing capacity of the overall structure. Under high load or complex terrain conditions, it is prone to twisting or deformation. Therefore, in this application, the frame body 10 includes two longitudinal beams 101 arranged side by side, which can provide a more stable foundation support for the sprayer frame, better distribute and bear the weight from the upper medicine tank and other components, improve the overall load-bearing capacity of the sprayer frame, and reduce the possibility of deformation or damage to the sprayer frame due to uneven stress. Secondly, two mounting plates 131 are arranged side by side on each longitudinal beam 101, and a connecting structure is connected between the two mounting plates 131, which further enhances the strength of the local structure and can provide multiple limiting points for the medicine tank. The connecting structure between the two mounting plates 131 can work together with the mounting plates 131 to further restrict the movement of the medicine tank.

[0039] The connecting structure includes a first connecting plate 133 located at the bottom of the mounting plate 131 and a second connecting plate 134 located at the top of the mounting plate 131. The double support design greatly enhances the rigidity and stability of the mounting plate 131, making the entire sprayer frame structure more robust and ensuring that the load is evenly distributed on the sprayer frame as much as possible, avoiding deformation or damage caused by local stress concentration. The first connecting plate 133 is used for the rear axle installation of the frame. The first connecting plate 133, the second connecting plate 134 and the mounting plate 131 together form an installation channel for the longitudinal beam 101 to be inserted, reducing the cost and space of designing the rear axle installation components separately, and making the sprayer frame more compact.

[0040] Furthermore, the end of the first connecting plate 133 extends beyond the edge of the mounting plate 131, increasing the contact area with the longitudinal beam 101 and thus enhancing the rigidity and load-bearing capacity of the entire structure. The portion of the first connecting plate 133 extending beyond the edge of the mounting plate 131 may be provided with a connecting hole 138 for mounting the rear axle of the frame body 10.

[0041] Specifically, the mounting plate 131 includes a first mounting portion 135 extending vertically along the frame body 10, and the connecting crossbeam 132 includes a limiting crossbeam 1321 connecting the two first mounting portions 135, forming a stable frame structure. This frame structure can effectively enhance the structural strength and rigidity of the frame body 10 in the corresponding area, improve the overall support capacity of the frame body 10 for various components, and enable it to better withstand various stresses and impacts generated during the movement of the sprayer frame. The medicine tank is longitudinally limited between the limiting crossbeam 1321 and the gearbox, which can more accurately determine the installation position of the medicine tank, prevent longitudinal displacement of the medicine tank during the movement of the sprayer frame as much as possible, and ensure that the medicine tank is always in the designed installation position, thereby ensuring the stability and reliability of the entire sprayer frame.

[0042] To facilitate the installation of the medicine box, the mounting plate 131 also includes a second mounting portion 136 extending longitudinally along the frame body 10. The connecting crossbeam 132 also includes a supporting crossbeam 1322 connecting the two second mounting portions 136. The medicine box is supported on the supporting crossbeam 1322. The supporting crossbeam 1322 provides direct and stable support for the medicine box, ensuring that the medicine box remains in the correct position as much as possible during the operation of the sprayer frame, thereby minimizing swaying or displacement due to unstable support. Since the supporting crossbeam 1322 connects the two second mounting portions 136, it can distribute the weight of the medicine box more evenly on the frame body, minimizing excessive local pressure. The second mounting portion 136 extending longitudinally along the frame body 10 and the supporting crossbeam 1322 connecting the two second mounting portions 136 form a stable longitudinal support structure, further enhancing the structural strength of the frame body 10. Compared to unidirectional support, this structure can better withstand the weight of the medicine tank itself and the longitudinal forces generated during the movement of the sprayer frame, such as inertial forces during acceleration and deceleration. This makes the installation of the medicine tank more stable and reduces the possibility of structural deformation or loosening due to longitudinal forces. When installing the medicine tank, it can be placed on the support beam 1322 and then simply secured. When it needs to be disassembled for maintenance or replacement, it can be easily removed from the support beam 1322 without complicated operations. The first mounting part 135 and the second mounting part 136 are L-shaped. The L-shaped structure provides support to the medicine tank in different directions, forming a natural anti-torsional structure. The L-shaped structure can also better adapt to the spatial shape of the sprayer frame.

[0043] To further enhance the structural strength of the mounting plate 131, a reinforcing part 139 is also included. The reinforcing part 139 connects between the first mounting part 135 and the second mounting part 136. The reinforcing part 139 effectively increases the connection strength between the first mounting part 135 and the second mounting part 136, allowing the entire mounting plate 131 to better distribute stress when subjected to external forces, reducing local stress concentration, thereby significantly improving the overall strength and load-bearing capacity of the mounting plate 131. This ensures that it can stably support components such as the medicine tank under conditions such as sprayer chassis. The reinforcing part 139, the first mounting part 135, and the second mounting part 136 are integrally formed, minimizing connection gaps or weak points between them, resulting in stronger structural integrity and stability. To facilitate the fixing of the medicine tank, the mounting plate 131 has multiple spaced mounting holes 137, which are connected to each other on the left and right sides of the mounting plate 131 of the chassis body 10. Multiple spaced mounting holes 137 provide more installation options. The mounting holes 137 on the mounting plates 131 on the left and right sides are connected to ensure the consistency and symmetry of the installation position as much as possible, avoiding imbalance caused by asymmetrical installation, and further improving the stability and safety of the whole machine. The medicine box can be fixed by passing bolts through the mounting holes 137 and tightening them with nuts.

[0044] To facilitate the installation of the transmission, the transmission mounting position 12 includes a transmission mounting bracket 121 located on each longitudinal beam 101. The transmission mounting brackets 121 on the two longitudinal beams 101 extend symmetrically and face each other and are spaced apart. The transmission mounting brackets 121 provide multi-point support, effectively preventing the transmission from shifting or loosening during operation. They also help to distribute the weight of the transmission evenly on the two longitudinal beams 101, avoiding local stress concentration.

[0045] To further increase the structural strength of the sprayer frame, a reinforcing crossbeam 102 connecting the two longitudinal beams 101 is provided between the gearbox mounting position 12 and the medicine tank mounting position 13. This provides additional lateral support, greatly enhancing the lateral rigidity of the sprayer frame and thus increasing the load-bearing capacity of the entire sprayer frame. It can distribute the load more evenly on the two longitudinal beams 101, avoid local stress concentration, and improve the overall stability and reliability of the equipment.

[0046] It should be noted that the top of the reinforcing crossbeam 102 is lower than the bottom of the longitudinal beam 101 to avoid interference with the gearbox and medicine tank mounted on the longitudinal beam 101.

[0047] Furthermore, the frame body 10 is also provided with a front axle mounting bracket 103 for mounting the front axle. The front axle mounting bracket 103 includes two support beams 104 arranged along the front and rear of the frame body 10 and connecting ribs 105 for connecting the two support beams 104. The two ends of the two support beams 104 are respectively connected to two longitudinal beams 101. The support beams 104 include inclined portions 106 that are inclined downward in the longitudinal direction and horizontal portions 107 that are arranged horizontally. The horizontal portions 107 are located between the two inclined portions 106, making the entire front axle mounting bracket 103 have a concave structure. The engine mounting position 11 includes engine mounting brackets 111 located on each longitudinal beam 101 and at least part of the front axle mounting bracket 103, thereby facilitating the installation of the engine. The engine mounting brackets on the two longitudinal beams 101 111 extends symmetrically and faces each other, with intervals between them. The front axle mounting bracket 103 connects the two longitudinal beams 101, further enhancing the lateral rigidity of the front end of the sprayer frame. This makes the entire sprayer frame a stable structural system, avoiding the need for a separate complex mounting structure for the engine and greatly saving space at the front end of the sprayer frame. This compact design makes the layout of the sprayer frame more reasonable, allowing the engine load to be transferred to the longitudinal beams 101 through the engine mounting bracket 111. Then, the longitudinal beams 101 and the front axle mounting bracket 103 connecting the longitudinal beams 101 evenly distribute the force to the entire sprayer frame. The reasonable force transmission path effectively reduces stress concentration, improves the stability of the sprayer frame under various working conditions, and ensures the safety of the sprayer during operation.

[0048] It should be noted that in this embodiment, one of the two support beams 104, the one closer to the engine mounting bracket 111, is used for engine mounting.

[0049] It should be noted that the engine mounting bracket 111 is a flat plate located at the bottom of the longitudinal beam 101, and the flat plate is provided with positioning holes 112 for engine positioning and installation.

[0050] It should be noted that the front end of the sprayer frame is provided with a reinforcing rib plate 108 for connecting the two longitudinal beams 101, which further enhances the structural strength of the sprayer frame.

[0051] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
