Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, specifically to a wood powder spreading mechanism and a wood powder spreading vehicle. Background Technology

[0002] In modern animal husbandry, the management of cattle farm floors is crucial for the healthy growth of cattle. The cleanliness of the farm floor directly affects the quality of the cattle's living environment, which in turn affects their disease incidence and growth performance. To keep the farm floor dry, comfortable, and absorb odors, wood dust is usually spread on the ground. However, currently, wood dust is mostly spread manually, making it difficult to ensure uniformity. Uneven spreading of wood dust will result in some areas failing to effectively perform its moisture-absorbing and deodorizing functions, while other areas will have excessively thick layers of wood dust, which not only wastes resources but may also impede the cattle's movement and increase the risk of slipping and injury.

[0051] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0052] Please see Figures 1-4 This application provides the following technical solutions:

[0053] A wood powder spreading mechanism includes a material carrying component 21, which has a cavity for holding wood powder. The material carrying component 21 has an inlet and an outlet. A dispersing component 22 is disposed outside the material carrying component 21, and the dispersing component 22 is connected to the outlet of the material carrying component 21. The dispersing component 22 can spread the wood powder from the material carrying component 21 outwards towards the outside of the vehicle body 1.

[0054] A first stirring component 23 and a second stirring component 24 are respectively provided inside the material carrying component 21. The first stirring component 23 is located on the discharge port side of the material carrying component 21, and the second stirring component 24 is located near the inlet of the material carrying component 21.

[0055] Wood dust enters the material carrying component 21 through the inlet and is then spread on the cattle farm ground by the dispersing component 22. Considering the potential for wood dust to clump, this solution includes a first stirring component 23 and a second stirring component 24 inside the material carrying component 21. These two stirring components agitate the inlet and outlet, where wood dust is more prone to accumulating and clumping, respectively, thus ensuring smooth discharge of the wood dust.

[0056] Based on the above implementation scheme, the material carrying component 21 includes a hopper 211 with a bucket-shaped structure. One end of the hopper 211 with a large opening is the feed inlet, and a through-hole is provided on the side wall of the hopper 211 away from the feed inlet as the discharge outlet. Several shovel teeth are provided on the feed inlet side of the hopper 211. A hopper connecting structure 212 is provided on the side of the hopper 211 away from the feed inlet to... Figure 2 Taking the direction shown as an example, the large opening end of the hopper 211, that is, the feed inlet, is located at the top, and the hopper connecting structure 212 is located at the bottom of the hopper 211. The hopper 211 is connected to the external structure through the hopper connecting structure 212.

[0057] like Figure 1 As shown, a hopper drive assembly 25 is also provided on the outside of the hopper 211. The hopper drive assembly 25 is linked with the hopper 211, and drives the hopper 211 to rotate through the hopper drive assembly 25. The hopper drive assembly 25 of this solution includes a hydraulic cylinder, one end of which is rotatably connected to the hopper 211, and the other end is rotatably connected to the external structure. By extending and retracting the hydraulic cylinder, the orientation of the feed inlet of the hopper 211 can be adjusted. Under the action of the hopper drive assembly 25, the opening of the hopper 211 is made to face the horizontal side. Using its own bucket structure, the wood powder accumulated on the opposite side can be shoveled into the hopper 211.

[0058] Based on the above implementation scheme, the bulk material assembly 22 includes a bulk material shell 221. The bulk material shell 221 has an internal channel. One end of the channel is connected to the discharge port of the hopper 211, and the other end faces outwards from the hopper 211. The channel of the bulk material shell 221 is connected to an air source, allowing airflow to be supplied into the bulk material shell 221. The air source for the bulk material shell 221 can be arranged in various ways. This scheme uses a fan 222 with blades. The air inlet of the fan 222 is connected to the discharge port of the hopper 211, and the air outlet is connected to the internal channel of the bulk material shell 221.

[0059] The blower 222 draws the wood powder inside the hopper 211 into the bulk material shell 221, and then blows it out towards the lateral side of the hopper 211. This method enables the rapid distribution of wood powder.

[0060] Based on the above implementation plan, see Figure 4 A discharge gate 223 is provided at the discharge port of the hopper 221. The discharge gate 223 is located inside the hopper 211 and is rotatably connected to the hopper 211. A gate handle is provided on the outside of the hopper 211. By rotating the gate handle, the discharge gate 223 can be closed or opened.

[0061] Based on the above implementation plan, see Figure 4 The first stirring assembly 23 includes a first stirring shaft 231 rotatably connected to the hopper 211. A first stirring drive 234, which is a motor, is provided at one end of the first stirring shaft 231 to drive the first stirring shaft 231 to rotate.

[0062] A first stirring element 232 and a stirring rod 233 are respectively arranged on the body of the first stirring shaft 231. The first stirring element 232 has a spiral structure and is arranged around the periphery of the first stirring shaft 231. One end of the stirring rod 233 is fixedly connected to the first stirring shaft 231, and the other end extends radially toward the first stirring shaft 231; one stirring rod 233 is symmetrically arranged on each side of the first stirring shaft 231. The two stirring rods 233 are located near the discharge port of the first stirring shaft 231; the first stirring element 232 is arranged on each side of the stirring rod 233.

[0063] It should be noted that the two first stirring elements 232 on both sides of the stirring rod 233 have opposite spiral directions. The first stirring element 232 is not a spiral blade structure, but a spiral rod structure.

[0064] This structure effectively disperses the wood dust near the discharge port of hopper 211, preventing the wood dust from clumping and causing blockage at the discharge port.

[0065] Based on the above implementation plan, see Figure 3 The second stirring assembly 24 includes a second stirring element 241 with a rectangular frame, and both ends of the second stirring element 241 are rotatably connected to the hopper 211. A second stirring drive element 242 is linked to the second stirring element 241, and the second stirring element 241 can be rotated by the second stirring drive element 242.

[0066] Because the feed inlet of hopper 211 in this design is less prone to wood powder clumping, the second stirring drive 242 is manually operated to save energy. A rod is used as the drive rod, with one end rotatably connected to the second stirring component 241. The drive rod and hopper 211 are inserted into each other, with sufficient room for movement at the insertion point. A handle is provided on the outer end of the drive rod. When the second stirring component 241 needs to be activated, the operator simply pushes or pulls the handle to make the second stirring component 241 swing back and forth, thus breaking up the wood powder.

[0067] This solution also provides a wood powder spreading cart, see [link / reference] Figure 5 and Figure 6 It includes a vehicle body 1, which is equipped with a power mechanism and a steering mechanism, and the aforementioned wood powder spreading mechanism 2 is installed on the vehicle body 1.

[0068] For ease of explanation, the forward direction of vehicle body 1 is considered as "front," and the reverse direction as "rear." Vehicle body 1 includes two front wheels 11 and one rear wheel 12. The two front wheels 11 are symmetrically arranged on the lower front side of vehicle body 1. The rear wheel 12 is located on the lower middle rear end of vehicle body 1 and is linked to the steering wheel. Because the wood powder spreading mechanism 2 needs to carry wood powder, and considering ease of observation for workers, the wood powder spreading mechanism 2 is located at the front of vehicle body 1.

[0069] In this design, the wood powder spreading vehicle uses a hydraulic motor to drive either the front wheel 11 or the rear wheel 12. Depending on the specific circumstances, it can be selected whether only the front wheel 11 is driven or both the front and rear wheels are driven. A reversing valve is installed in the oil supply path of the driving motor, which controls whether the vehicle body 1 moves forward or backward.

[0070] For ease of operation, the directional valve is controlled via a foot pedal. The operator presses or releases the pedal to control the valve, and the hydraulic system directly supplies hydraulic oil to the travel motor. This causes the trolley to jerk forward or backward upon starting, resulting in excessive acceleration and noticeable shaking of the vehicle body, causing discomfort to the operator. Therefore, an energy storage tank is installed in the directional valve and hydraulic oil supply path to temporarily store the hydraulic oil before discharging it. The energy storage tank in this design uses a bladder-type structure. When the foot pedal is pressed or released, the hydraulic system first sends hydraulic oil to the energy storage tank, slowly building up system pressure. Only when the system pressure is sufficient to drive the travel motor will the trolley move forward or backward. This results in gradual acceleration, preventing slippage and operator swaying. The acceleration during trolley startup can be adjusted by selecting the appropriate energy storage tank volume.

[0071] Based on the above implementation scheme, cleaning brushes can also be installed at the front and sides of the vehicle body 1. The front cleaning brush scrapes away dirt from the ground in the direction of the vehicle body 1's forward movement, while the side cleaning brush is installed in front of the outlet of the bulk material shell 221 and uses a rotating brush body to sweep dirt away from the area where wood powder is spread.
