It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a cow manure crushing and spreading device for forage planting, such as Figure 1-4 As shown, the cow manure crushing and spreading device for forage planting includes: a spreading box 1; a crushing box 2, which is located above the spreading box 1; a sieve plate 3, which is fixedly installed in the crushing box 2; several drive rods 4, which are all located in the crushing box 2 above the sieve plate 3; several sets of crushing blades 5, which are respectively fixedly installed on the several drive rods 4, and the crushing blades 5 located at the top of the drive rods 4 can contact the sieve plate 3; a guide plate 6, which is fixedly installed in the spreading box 1 and has several spreading openings; a vertical drive mechanism, which is located on the crushing box 2 and is used to drive the crushing blades 5 to rotate in the vertical direction to crush the cow manure for forage planting; and a horizontal drive mechanism, which is located on the crushing box 2 and is used to drive the crushing blades 5 to rotate in the horizontal direction to crush the cow manure for forage planting.

[0024] In this embodiment, the spreading box 1 serves as the container part of the entire device, used to collect and store the crushed cow manure. This facilitates the centralized processing and subsequent spreading of the cow manure.

[0025] The crushing box 2 is located above the spreading box 1 and is the main area for crushing cow manure. Its internal crushing mechanism effectively crushes the cow manure, improving crushing efficiency.

[0026] The sieve plate 3 is fixedly installed in the crushing box 2 to screen the crushed cow manure, ensuring that the particle size of the cow manure meets the requirements. This ensures that the crushed cow manure is finer, which is beneficial for the absorption of plant roots.

[0027] The drive rod 4 is positioned above the screen plate 3 in the crushing box 2, serving as a support and driving component for the crusher blade 5. Rotation of the drive rod 4 drives the crusher blade 5 to perform the crushing operation.

[0028] The crushing blade 5 is fixedly mounted on the drive rod 4 and contacts the screen plate 3 to crush cow dung. The rotation of the crushing blade 5 effectively cuts and crushes the cow dung, improving the crushing effect.

[0029] The guide plate 6 is fixedly installed in the spreading box 1, and has several spreading openings on it to evenly spread the crushed cow manure into the soil. This ensures that the cow manure is evenly distributed and improves the fertilization effect.

[0030] A vertical drive mechanism is mounted on the crushing box 2 to drive the crushing blades 5 to rotate vertically. By changing the crushing direction of the crushing blades 5, the crushing efficiency is increased, and the feed absorption rate is improved.

[0031] A horizontal drive mechanism is mounted on the crushing box 2 to drive the crushing blades 5 to rotate horizontally. In conjunction with the vertical drive mechanism, this enables multi-directional crushing by the crushing blades 5, further improving crushing efficiency and forage absorption rate.

[0032] In a further preferred embodiment of the present invention, the vertical drive mechanism includes a drive cylinder 7 rotatably installed in the crushing box 2, a drive rod 4 rotatably connected to the drive cylinder 7, a drive motor 8 fixedly installed on one side of the crushing box 2, and the output shaft of the drive motor 8 fixedly connected to the drive cylinder 7.

[0033] In this embodiment, the drive cylinder 7 is rotatably installed in the crushing box 2, serving as a rotational support and power transmission component for the drive rod 4. The rotation of the drive cylinder 7 causes the drive rod 4, which is rotatably connected to it, to rotate as well. Through the rotation of the drive cylinder 7, the crushing blade 5 is driven vertically, increasing the crushing direction of the crushing blade 5 and thus improving the crushing efficiency and effect of the cow dung.

[0034] The drive rod 4 is connected to the drive cylinder 7 via a bearing, so that the rotation of the drive cylinder 7 can drive the drive rod 4 to rotate together. This rotating connection method ensures that the drive rod 4 can rotate stably and smoothly under the drive of the drive cylinder 7, thereby driving the crusher 5 to perform crushing operations.

[0035] The drive motor 8 is fixedly installed on one side of the crushing box 2, and its output shaft is fixedly connected to the drive cylinder 7. As the power source of the entire vertical drive mechanism, the drive motor 8 provides stable and controllable power output, ensuring that the crusher blade 5 can continuously and efficiently carry out crushing operations.

[0036] In a further preferred embodiment of the present invention, the transverse drive mechanism includes a toothed plate 9 fixedly installed at one end of the drive cylinder 7, a mounting bracket 10 fixedly installed on one side of the crushing box 2, a driven rod 11 rotatably installed in the mounting bracket 10, a driven gear 12 fixedly installed on the driven rod 11, the driven gear 12 meshing with the toothed plate 9, and a bevel gear 13 meshing with the outermost drive rod 4 fixedly installed on one end of the driven rod 11 that extends slidably into the drive cylinder 7.

[0037] In this embodiment, the toothed plate 9 is fixedly mounted on one end of the drive cylinder 7, serving as a transmission component that meshes with the driven gear 12. When the drive cylinder 7 rotates, the toothed plate 9 rotates accordingly, driving the driven gear 12 meshing with it to rotate. The meshing transmission between the toothed plate 9 and the driven gear 12 realizes the conversion of the rotation of the drive cylinder 7 into the rotation of the driven rod 11, providing a power source for the transverse drive mechanism.

[0038] Mounting bracket 10 is fixedly installed on one side of crushing box 2, serving as a support and mounting component for driven rod 11. Driven rod 11 is mounted on mounting bracket 10 via bearings, enabling stable and smooth rotation. Mounting bracket 10 provides stable support and a suitable installation environment for driven rod 11, ensuring its normal and efficient rotation.

[0039] Driven rod 11 is rotatably mounted in mounting bracket 10, on which driven gear 12 and bevel gear 13 are fixedly mounted. Driven gear 12 meshes with toothed plate 9, and bevel gear 13 meshes with bevel gear 13 fixedly mounted on the outermost drive rod 4. As the core component of the transverse drive mechanism, driven rod 11, through driven gear 12 and bevel gear 13, converts the rotation of drive cylinder 7 into the horizontal rotation of drive rod 4, thereby achieving the horizontal drive of crusher 5.

[0040] Driven gear 12 is fixedly mounted on driven rod 11 and meshes with toothed plate 9. When toothed plate 9 rotates, it drives driven gear 12 to rotate, which in turn drives driven rod 11 to rotate. The meshing transmission between driven gear 12 and toothed plate 9 ensures that the rotation of drive cylinder 7 can be stably and efficiently converted into the rotation of driven rod 11.

[0041] A bevel gear 13 is fixedly mounted on one end of the driven rod 11 that slides into the drive cylinder 7, and meshes with a bevel gear 13 fixedly mounted on the outermost drive rod 4. When the driven rod 11 rotates, it drives the bevel gear 13 to rotate, which in turn drives the meshing drive rod 4 to rotate horizontally. The meshing transmission of the bevel gear 13 converts the rotation of the driven rod 11 into the horizontal rotation of the drive rod 4, thereby driving the crusher 5 horizontally. This design not only improves the crushing efficiency of the crusher 5, but also makes the entire device more compact and reliable.

[0042] In a further preferred embodiment of the present invention, two guide grooves 14 are provided on both sides of the top of the dispersing box 1. A guide rod 15 is slidably installed in the guide groove 14. A guide spring 16 is sleeved on the guide rod 15. The two ends of the guide spring 16 are fixedly connected to the dispersing box 1 and the crushing box 2, respectively.

[0043] In this embodiment, guide grooves 14 are formed on both sides of the top of the dispersing box 1, serving as sliding tracks for the guide rods 15. The shape and size of the guide grooves 14 match the guide rods 15, ensuring that the guide rods 15 can slide stably and smoothly within them.

[0044] The guide groove 14 provides a clear sliding path for the guide rod 15, ensuring the stable movement of the crushing box 2 in the vertical direction, and also helping to maintain the relative positional relationship between the crushing box 2 and the dispersing box 1.

[0045] The guide rod 15 is slidably installed in the guide groove 14, serving as a connecting component between the crushing box 2 and the dispersing box 1. One end of the guide rod 15 is fixedly connected to the crushing box 2, while the other end can slide freely in the guide groove 14.

[0046] The guide rod 15 not only connects the crushing box 2 and the spreading box 1, but also enables the crushing box 2 to move vertically through its sliding in the guide groove 14. This design allows the crushing box 2 to vibrate up and down as needed to adapt to the screening requirements.

[0047] The guide spring 16 is sleeved on the guide rod 15, and its two ends are fixedly connected to the dispersing box 1 and the crushing box 2, respectively. When the guide spring 16 is in a compressed state, it will generate an upward thrust on the crushing box 2, thereby playing a role in buffering and shock absorption.

[0048] The guide spring 16 effectively mitigates the vibration and impact generated during the crushing process in the crushing box 2, protecting the integrity of the crushing box 2 and its internal components. Simultaneously, the guide spring 16 also adjusts the distance between the crushing box 2 and the spreading box 1, making the connection between them tighter and more stable.

[0049] In a further preferred embodiment of the present invention, two push motors 17 are fixedly installed on both sides of the top of the dispersing box 1, and a cam 18 is fixedly installed on the output shaft of the push motor 17. Two top wheels 19 are fixedly installed on both sides of the bottom of the crushing box 2, and the top wheels 19 slide in contact with the cam 18.

[0050] In this embodiment, the push motor 17 is fixedly installed on both sides of the top of the spreading box 1, serving as the power source for the lifting mechanism. The start and stop of the push motor 17 can control the rotation of the output shaft, thereby realizing the lifting and lowering of the crushing box 2.

[0051] The pusher motor 17 provides a stable and controllable power output, ensuring that the crushing box 2 can vibrate smoothly as needed, thereby adapting to the working requirements of screening.

[0052] Cam 18 is fixedly mounted on the output shaft of push motor 17, serving as a transmission component that slides in contact with top wheel 19. When push motor 17 is started, cam 18 rotates accordingly and, through sliding contact with top wheel 19, pushes crushing box 2 to vibrate up and down.

[0053] The rotation of cam 18 and its sliding contact with top wheel 19 convert the rotation of push motor 17 into the up-and-down vibration motion of crushing box 2. This design is not only simple and compact in structure, but also enables the crushing box 2 to vibrate smoothly.

[0054] The top wheel 19 is fixedly installed on both sides of the bottom of the crushing box 2 and slides in contact with the cam 18. When the cam 18 rotates, it will push the crushing box 2 to vibrate up and down through the sliding contact with the top wheel 19.

[0055] The top roller 19, as a component that slides in contact with the cam 18, bears the weight of the crushing box 2 and its internal components, and achieves the vibration movement of the crushing box 2 through its sliding contact with the cam 18. This design not only improves the stability and durability of the screening mechanism, but also makes the vibration of the crushing box 2 more stable and controllable.

[0056] In a further preferred embodiment of the present invention, a feeding hose 20 is fixedly installed between the spreading box 1 and the crushing box 2, a support frame 21 is fixedly installed on the spreading box 1, a feeding hopper 22 is fixedly installed on the top of the support frame 21, and a feeding hose 23 is fixedly installed between the feeding hopper 22 and the crushing box 2.

[0057] In this embodiment, the feeding hose 20 is fixedly installed between the spreading box 1 and the crushing box 2, serving as a transmission channel for the crushed cow manure. After the cow manure in the crushing box 2 is crushed, it will fall into the spreading box 1 through the feeding hose 20 for subsequent spreading operations.

[0058] The feeding hose 20 ensures that the crushed cow manure can be smoothly and quickly transported to the spreading box 1, improving the overall efficiency of the device. At the same time, the feeding hose 20 also has a certain degree of flexibility and elasticity, allowing it to adapt to the vibration of the crushing box 2 and ensuring the continuity and stability of material transport.

[0059] The support frame 21 is fixedly installed on the distribution box 1, serving as a support component for the feed hopper 22. The shape and size of the support frame 21 match the feed hopper 22, ensuring that the feed hopper 22 is stably and securely installed on the distribution box 1.

[0060] The support frame 21 provides stable support for the feed hopper 22, ensuring that the feed hopper 22 can receive and transfer materials normally and efficiently. At the same time, the support frame 21 also has a certain strength and rigidity, which can withstand the impact and vibration generated during material transfer.

[0061] The feed hopper 22 is fixedly installed on the top of the support frame 21 as the material inlet component. The user can pour the cow dung to be crushed into the feed hopper 22, and then the material will enter the crushing box 2 through the feed hose 23 for crushing.

[0062] The feed hopper 22 facilitates the user's pouring of materials into the device, improving the overall ease of use and operation. Simultaneously, the feed hopper 22 has a certain capacity and shape design, ensuring that materials can smoothly enter the feed hose 23.

[0063] The feed hose 23 is fixedly installed between the feed hopper 22 and the crushing box 2, serving as a material transfer channel. After the material is poured into the feed hopper 22, it will enter the crushing box 2 through the feed hose 23 for crushing.

[0064] The feed hose 23 ensures that materials can be smoothly and quickly transferred into the crushing box 2, improving the overall efficiency of the device. At the same time, the feed hose 23 also has a certain degree of flexibility and elasticity, enabling it to withstand the impacts and vibrations generated during material transport.

[0065] In a further preferred embodiment of the present invention, a sprocket 24 is fixedly installed on one end of the drive rod 4 extending into the drive cylinder 7, and a chain 25 is sleeved on several of the sprockets 24.

[0066] In this embodiment, the sprocket 24 is fixedly mounted on one end of the drive rod 4 that extends into the drive cylinder 7. As a transmission component of the chain 25, the sprocket 24 rotates as the drive rod 4 rotates. The sprocket 24 effectively converts the rotation of the drive rod 4 into the transmission of the chain 25. This design is not only simple and compact, but also effectively transmits torque and speed, ensuring that the drive rod 4 rotates stably and efficiently.

[0067] A chain 25 is mounted on several sprockets 24, forming a closed-loop transmission system. When one sprocket 24 rotates, it drives the other sprockets 24 to rotate synchronously via the chain 25. The chain 25, acting as a transmission medium, can transmit the rotation of one sprocket 24 to the other sprockets 24, thereby achieving synchronous rotation of multiple drive rods 4. This design not only improves transmission efficiency but also makes the entire transmission system more stable and reliable.

[0068] The combination of sprocket 24 and chain 25 enables the synchronous rotation of multiple drive rods 4, thereby improving the efficiency of the entire transmission system. This design allows the crusher blade 5 to crush cow dung more stably and efficiently.

[0069] Compared to other transmission methods, the drive mechanism of sprocket 24 and chain 25 offers greater structural stability and durability. This design enables the entire device to maintain high stability and reliability during extended operation.

[0070] In summary, compared with related technologies, by adopting a combination design of components such as drive rod 4, drive cylinder 7, crushing blade 5 and spreading box 1, this device can efficiently crush cow manure into fine particles and spread them evenly on the forage through spreading box 1, thereby improving the utilization rate of cow manure and the growth quality of forage.

[0071] This device employs a combination design of sprocket 24 and chain 25 in its transmission mechanism, ensuring the synchronous rotation of multiple drive rods 4 and improving the stability and reliability of the entire device. Simultaneously, the connection and fixing methods between various components have been optimized, enabling the entire device to maintain high stability and durability during long-term operation.

[0072] This device is designed with the actual needs of users in mind and adopts a simple and easy-to-operate method. Users only need to pour the cow dung to be crushed into the feed hopper 22 and start the motor to realize the crushing and spreading of cow dung.
