Description

Technical Field

[0001] This utility model relates to the field of fertilizer mixing and discharging technology, specifically to a mobile fertilizer mixing and discharging device. Background Technology

[0002] Mobile fertilizer mixing and discharging devices should be designed to meet the needs of modern agriculture, featuring high efficiency, precision, intelligence, and flexibility, providing a more scientific and environmentally friendly solution for farmland fertilization. The application of such equipment can not only improve fertilizer utilization efficiency and reduce resource waste, but also promote the sustainable development of agricultural production.

[0003] A mixing and discharging device (publication number: CN221344848U) disclosed includes a housing, an inlet fixedly connected to the outer side of the housing, an outlet at the bottom of the housing, a mounting plate fixedly connected to the outer side of the housing, support legs fixedly connected at equal intervals to the bottom of the mounting plate, a rotating rod rotatably connected to the top of the inner wall of the housing, and a motor fixedly mounted on the top of the housing. The bottom of the motor output shaft is fixedly connected to the top of the rotating rod. This invention addresses the problem that, because the device lacks a stirring mechanism, it cannot effectively mix various feeds. Mixing feed by shaking is difficult to achieve uniform mixing, resulting in some particles or components not being fully mixed, affecting the nutritional balance and stability of the feed. Furthermore, because the feed raw materials contain moisture, some feed often sticks to the device wall during mixing, making it difficult to discharge and causing waste during discharging, which is detrimental to practical use.

[0004] In the aforementioned application, the interaction between the shell and the shaking drive component makes it difficult to prevent fertilizer from adhering to the shell wall during the mixing process. This results in a large amount of fertilizer adhering to the shell wall during mixing and discharging, which not only wastes fertilizer raw materials but may also affect the purity of the subsequent mixed fertilizer due to the deterioration of residual materials. Therefore, we propose a mobile fertilizer mixing and discharging device. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a mobile fertilizer mixing and discharging device, which solves the technical problem of preventing fertilizer from sticking to the wall in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a mobile fertilizer mixing and discharging device, comprising: a caster wheel, a support plate fixedly connected to the top of the caster wheel, a base plate fixedly connected to the top of the support plate, a motor fixedly connected to the top of the base plate, a stirring shaft fixedly connected to the output shaft of the motor, a stirring rod fixedly connected to the circumferential surface of the stirring shaft, one end of the stirring shaft penetrating through the outer wall of the mixing tank, a support leg fixedly connected to the bottom of the mixing tank, a discharge port opened on the circumferential surface of the mixing tank, a cover plate slidably connected to the side of the discharge port, a fixing block fixedly connected to the side of the cover plate, and an anti-wall-hanging device provided on the top of the support plate.

[0007] For example, in at least one embodiment of this utility model, a mobile fertilizer mixing and discharging device further includes: the anti-wall-hanging device comprising a rotating shaft, one end of which is rotatably connected to the top of a support plate; the rotating shaft is connected to the circumferential surface of a stirring shaft via a belt drive; the bottom of the rotating shaft is rotatably connected to the top of the support plate; a half-gear is fixedly connected to one end of the rotating shaft; a rack is slidably connected to the top of the support plate; a fixing rod is fixedly connected to the side of the rack; a force-bearing plate is fixedly connected to the side of the fixing rod; a spring is fixedly connected to one end of the rack; a force-bearing block is fixedly connected to one end of the spring; the side of the force-bearing block is fixedly connected to the side of the support plate; and a connecting rod is fixedly connected to the side of the fixing rod. The purpose of this device is to provide a stable mixing process, preventing the equipment from sticking to or getting stuck in the surrounding environment during mixing, while ensuring smooth material discharge. The anti-wall-hanging device achieves self-protection of the equipment during operation through a series of mechanical connections and spring supports.

[0008] The stirring shaft is rotatably connected to the circumference of the rotating shaft via a belt, which is located directly above the support plate. This design provides power transmission, speed adjustment, and shock absorption through the belt, thereby improving the performance and stability of the stirring device.

[0009] The half gear is located directly above the support plate, and the half gear meshes with the rack. The side of the fixing rod is located on the side of the mixing tank. The main purpose of this combination structure is to ensure the stability of the mixing equipment during operation and prevent it from being affected by objects stuck to the wall or jammed. At the same time, the cooperation of the gear and rack provides an adaptive adjustment mechanism.

[0010] The device is equipped with four casters, symmetrically arranged along the vertical central axis of the support plate. It also features several stirring rods arranged in a circumferential array on the circumferential surface of the stirring shaft. The symmetrical distribution of the four casters evenly distributes the weight of the equipment, maintaining stability during movement and preventing tilting or imbalance. Furthermore, the four casters prevent any single caster from bearing excessive weight, thus avoiding tilting. By arranging multiple stirring rods on the circumferential surface, this design ensures even distribution of stirring force, reducing localized overload and over-stirring, and improving work efficiency and the uniformity of stirring.

[0011] The number of support legs is four, and they are arranged in a circumferential array on the circumferential surface of the mixing tank. The mixing tank is located on the displacement trajectory of the force plate. The design of the four support legs ensures the balance and stability of the mixing tank under different working environments, prevents tilting or movement, and aligns the force-bearing area of ​​the mixing tank with the displacement trajectory of the force plate. This can effectively distribute pressure, reduce direct contact friction between the mixing tank and other components, and thus extend the service life of the equipment.

[0012] According to another aspect, at least one embodiment of this utility model also provides a mobile fertilizer mixing and discharging device, comprising: a pushing device disposed on the side of the mixing tank; the pushing device including a fixed platform; the bottom of the fixed platform being fixedly connected to the top of a support plate; a sliding rod slidably connected to the top of the fixed platform; a force-bearing rod fixedly connected to the side of the sliding rod; the side of the force-bearing rod being fixedly connected to the side of a fixed block; a return spring fixedly connected to one end of the sliding rod; one end of the return spring fixedly connected to the side of a fixed plate; the side of the fixed plate being fixedly connected to the side of the fixed platform; and a striking rod fixedly connected to the side of the sliding rod. The sliding rod, in cooperation with the return spring, can return to its original position after operation. The elasticity of the return spring helps the pushing device maintain a certain pressure or displacement. Through the rebound action of the return spring, the pushing device can automatically return to its initial state after completing one operation, avoiding excessive wear or unnecessary losses.

[0013] For example, in at least one embodiment of the present invention, a mobile fertilizer mixing and discharging device is provided, which further includes: the sliding rod is located directly above the fixed platform, and the side of the force-bearing rod is fixedly connected to the side of the fixed block. The purpose of these components working together is to ensure the stability of the mechanical system during movement, control the displacement, and be able to withstand and transmit external forces and loads, so as to avoid deviation or failure.

[0014] The side of the impact rod is located on the side of the connecting rod, and the impact rod is located on the displacement trajectory of the connecting rod. Because the impact rod is located on the displacement trajectory of the connecting rod, when the connecting rod moves to a certain position, it will impact the impact rod, thereby restricting the connecting rod from continuing to move. This design is usually used to prevent excessive displacement of mechanical parts and protect the structure of the device from damage.

[0015] The side of the sliding rod is located on the side of the impact rod, and the end of the sliding rod away from the force-bearing rod is located on the side of the fixed plate. This design is mainly for precise control of the movement of the sliding rod. Through the cooperation of the impact rod and the fixed plate, excessive displacement of the sliding rod is limited, and the stability and reliability of the mechanical equipment are ensured. Proper alignment and stable support of the sliding rod can improve the service life of the entire device and ensure smooth and safe operation of the equipment during fertilizer mixing and discharge.

[0016] The side of the force-bearing rod is located on the side of the mixing tank, and the fixing block is located on the displacement trajectory of the sliding rod. The force-bearing rod helps to share the external force, while the fixing block controls the range of motion of the sliding rod to prevent it from exceeding the trajectory, thus ensuring the smooth and efficient operation of the entire system.

[0017] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the mixing of components such as a rotating shaft, belt, half-gear, rack, fixed rod, force plate, spring, force block, and connecting rod achieves a multi-directional, multi-angle mixing of fertilizer materials through the coordinated operation of several mixing rods arranged in an array around the circumference of the mixing shaft. This avoids problems such as local material accumulation or insufficient mixing, ensuring a stable fertilizer composition ratio. The motor drives the mixing shaft, providing continuous and stable power for the mixing process. Combined with the reasonable layout of the mixing rods, the mixing time is effectively shortened. Four symmetrically distributed casters not only allow for flexible movement of the equipment but also evenly distribute the weight of the equipment, preventing tilting or imbalance caused by a shift in the center of gravity during movement, ensuring stable operation of the equipment in different locations. The anti-wall-hanging device transmits the power of the mixing shaft to the rotating shaft through belt transmission, driving the half-gear and rack to mesh. Combined with the elasticity of the spring, the fixed rod drives the force plate to reciprocate, striking the outer wall of the mixing tank to prevent material inside from sticking or getting stuck, ensuring that the mixing operation is not disturbed.

[0018] In this invention, the automatic reset function of mechanical actions is achieved through the cooperation of the sliding rod and the return spring. After the device completes one discharge operation, the rebound of the return spring can drive the sliding rod to quickly return to the initial position. The trajectory coordination of the impact rod and the connecting rod forms a precise limit protection system. Since the impact rod is on the displacement trajectory of the connecting rod, when the connecting rod moves to the limit position, the collision between the two will force the component to continue moving, promoting the coordinated work of the device, the anti-wall-hanging device, and the stirring system, forming a continuous mechanical linkage mechanism. The movement of the connecting rod triggers the impact rod, which in turn drives the sliding rod to control the opening and closing of the discharge port, realizing the orderly connection of stirring, anti-wall-hanging, and discharge operations. This linkage not only improves the integration level of the equipment, but also ensures that the fertilizer can be discharged quickly and smoothly after being mixed evenly, reducing material residue and improving the quality of fertilizer mixing and discharge efficiency.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0023] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0028] like Figures 1-6 As shown, a mobile fertilizer mixing and discharging device according to an embodiment of the present invention is illustrated, comprising: a caster wheel 1, a support plate 2 fixedly connected to the top of the caster wheel 1, a base plate 3 fixedly connected to the top of the support plate 2, a motor 4 fixedly connected to the top of the base plate 3, a stirring shaft 5 fixedly connected to the output shaft of the motor 4, a stirring rod 6 fixedly connected to the circumferential surface of the stirring shaft 5, a rotating shaft 131 being driven and connected to the circumferential surface of the stirring shaft 5 via a belt 132, a support leg 8 fixedly connected to the bottom of the mixing tank 7, a discharge port 9 opened on the circumferential surface of the mixing tank 7, a cover plate 10 slidably connected to the side of the discharge port 9, a fixing block 11 fixedly connected to the side of the cover plate 10, a collection box 12 fixedly connected to the top of the support plate 2, and an anti-wall-hanging device 13 provided on the top of the support plate 2.

[0029] In some examples, the anti-wall-hanging device 13 includes a rotating shaft 131, one end of which is rotatably connected to the top of the support plate 2. The rotating shaft 131 is driven by a belt 132 to a stirring shaft 5. A half-gear 133 is fixedly connected to one end of the rotating shaft 131. A rack 134 is slidably connected to the top of the support plate 2. A fixing rod 135 is fixedly connected to the side of the rack 134. A force-bearing plate 136 is fixedly connected to the side of the fixing rod 135. A spring 137 is fixedly connected to one end of the rack 134. A force-bearing block 138 is fixedly connected to one end of the spring 137. The side of the force-bearing block 138 is fixedly connected to the side of the support plate 2. A connecting rod 139 is fixedly connected to the side of the fixing rod 135. The purpose of this device is to provide a stable stirring process, preventing the equipment from sticking to or getting stuck in the surrounding environment during stirring, while ensuring smooth material discharge. The anti-wall-hanging device 13 achieves self-protection during operation through a series of mechanical connections and the support of the spring 137.

[0030] The stirring shaft 5 is rotatably connected to the circumferential surface of the rotating shaft 131 via a belt 132. The belt 132 is located directly above the support plate 2. This design provides power transmission, speed adjustment and shock absorption through the belt 132, thereby improving the performance and stability of the stirring device.

[0031] The half gear 133 is located directly above the support plate 2. The half gear 133 meshes with the rack 134. The side of the fixing rod 135 is located on the side of the mixing tank 7. The main purpose of this combination structure is to ensure the stability of the mixing equipment during operation and prevent it from being affected by objects stuck or jammed in the environment. At the same time, the cooperation of the gear and rack 134 provides an adaptive adjustment mechanism.

[0032] Four casters 1 are provided, symmetrically arranged along the vertical central axis of the support plate 2. Several stirring rods 6 are arranged in a circumferential array on the circumferential surface of the stirring shaft 5. The symmetrical distribution of the four casters 1 evenly distributes the weight of the equipment, maintaining stability during movement and preventing tilting or imbalance. Furthermore, the four casters prevent any single caster from bearing excessive weight, thus avoiding tilting. By arranging multiple stirring rods 6 on the circumferential surface, this design ensures even distribution of stirring force, reducing localized overload and over-stirring, and improving work efficiency and the uniformity of stirring.

[0033] The number of support legs 8 is set to four, and they are arranged in a circumferential array on the circumferential surface of the mixing tank 7. The mixing tank 7 is located on the displacement trajectory of the force plate 136. The design of the four support legs 8 ensures the balance and stability of the mixing tank 7 under different working environments, prevents tilting or movement, and connects the force-bearing area of ​​the mixing tank 7 with the displacement trajectory of the force plate 136, which can effectively distribute the pressure, reduce the direct contact friction between the mixing tank 7 and other components, and thus extend the service life of the equipment.

[0034] For example, such as Figures 1-6 As shown, the equipment moves as a whole thanks to four omnidirectional wheels 1 at the bottom. These wheels are symmetrically distributed and can evenly bear the weight of the equipment, making it easy to move between different locations. When the motor 4 starts, it drives the stirring shaft 5 to rotate. Several stirring rods 6 are installed on the stirring shaft 5 to ensure that the fertilizer is mixed evenly. When the stirring shaft 5 rotates, it is connected to the rotating shaft 131 via the belt 132. The half gear 133 on the rotating shaft 131 rotates along with it. The half gear 133 meshes with the rack 134, which pushes the rack 134 to move in a straight line. One end of the rack 134 has a spring 137. When it is pushed to a certain extent, the elastic force of the spring 137 will push the rack 134 back. In this way, the rack 134 moves back and forth with the fixed rod 135. The force plate 136 on the fixed rod 135 moves back and forth along with it. The mixing tank 7 is located on the displacement trajectory of the force plate 136 and will continuously knock on the tank wall. This prevents the fertilizer from sticking to the tank and avoids sticking to the wall, which would affect the mixing.

[0035] like Figures 1-6As shown, this invention illustrates a mobile fertilizer mixing and discharging device according to another embodiment of the present invention. At least one embodiment of the present invention also provides a mobile fertilizer mixing and discharging device, comprising: a pushing device 14 disposed on the side of a mixing tank 7; the pushing device 14 includes a fixed platform 141; the bottom of the fixed platform 141 is fixedly connected to the top of a support plate 2; a sliding rod 142 is slidably connected to the top of the fixed platform 141; a force-bearing rod 143 is fixedly connected to the side of the sliding rod 142; the side of the force-bearing rod 143 is fixedly connected to the side of a fixed block 11; a return spring 144 is fixedly connected to one end of the sliding rod 142; one end of the return spring 144 is fixedly connected to the side of a fixed plate 145; the side of the fixed plate 145 is fixedly connected to the side of the fixed platform 141; and a striking rod 146 is fixedly connected to the side of the sliding rod 142. The sliding rod 142, through its cooperation with the return spring 144, can return to its original position after operation. The elasticity of the return spring 144 helps the pushing device 14 maintain a certain pressure or displacement. By means of the rebound action of the return spring 144, the push device 14 can automatically return to the initial state after completing one operation, thus avoiding excessive wear or unnecessary damage.

[0036] In some examples, the sliding rod 142 is located directly above the fixed platform 141, and the return spring 144 is located directly above the fixed platform 141. The purpose of these components working together is to ensure the stability of the mechanical system during movement, control displacement, and withstand and transmit external forces and loads to avoid deviations or failures.

[0037] The side of the impact rod 146 is located on the side of the connecting rod 139. The impact rod 146 is located on the displacement trajectory of the connecting rod 139. Because the impact rod 146 is located on the displacement trajectory of the connecting rod 139, when the connecting rod 139 moves to a certain position, it will impact the impact rod 146, thereby restricting the connecting rod 139 from continuing to move. This design is usually used to prevent excessive displacement of mechanical parts and protect the structure of the device from damage.

[0038] The side of the sliding rod 142 is located on the side of the impact rod 146, and the end of the sliding rod 142 away from the force-bearing rod 143 is located on the side of the fixed plate 145. This design is mainly for precise control of the movement of the sliding rod 142. Through the cooperation of the impact rod 146 and the fixed plate 145, excessive displacement of the sliding rod 142 is limited, and the stability and reliability of the mechanical equipment are ensured. The proper alignment and stable support of the sliding rod 142 can improve the service life of the entire device and ensure smooth and safe operation of the equipment during fertilizer mixing and discharge.

[0039] The side of the force-bearing rod 143 is located on the side of the mixing tank 7, and the fixing block 11 is located on the displacement trajectory of the sliding rod 142. The force-bearing rod 143 helps to share the external force, while the fixing block 11 controls the movement range of the sliding rod 142 to prevent it from exceeding the trajectory, thus ensuring the smooth and efficient operation of the entire system.

[0040] For example, such as Figures 1-6 As shown, the core of the pushing device 14 is the sliding rod 142 on the fixed platform 141. It can slide back and forth on the fixed platform 141. The side of the sliding rod 142 is connected to the force rod 143, which is fixed to the fixing block 11 of the cover plate 10. Therefore, when the sliding rod 142 moves, it can open and close the discharge port 9 of the cover plate 10. The other end of the sliding rod 142 is equipped with a return spring 144, which is fixed to the fixed plate 145. When discharging, the sliding rod 142 is pushed open, and the return spring 144 is stretched. After discharging, the return spring 144 will retract by itself, pulling the sliding rod 142 back to its original position. In this way, the cover plate 10 will automatically close. The side of the sliding rod 142 also has There is a striking rod 146, which is aligned with the connecting rod 139 in the anti-wall-hanging device 13. When the anti-wall-hanging device 13 is working, the connecting rod 139 will move back and forth. When it moves to a certain position, it will hit the striking rod 146. The connecting rod 139 pushes the striking rod 146, and the striking rod 146 drives the sliding rod 142 to move forward. When the anti-wall-hanging device 13 is working, the connecting rod 139 drives the striking rod 146, and the striking rod 146 pushes the sliding rod 142. The sliding rod 142 opens the cover plate 10 through the force rod 143 to let the fertilizer out. After the discharge is completed, the return spring 144 pulls back the sliding rod 142, and the cover plate 10 closes. At the same time, it also drives the connecting rod 139 to reset. One link after another ensures smooth discharge and automatic reset.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
