Description

Technical Field

[0001] This utility model relates to the field of straw crushing technology, and in particular to a vibrating feeding device for a straw crusher. Background Technology

[0002] Straw is the residue left after harvesting crops, including corn stalks, rice straw, wheat straw, etc. In agricultural production, straw usually needs to be crushed for better utilization. Traditional straw crushers typically use mechanical crushing methods. The feeding structure of general straw crushers is relatively simple. Because the straw is piled up after harvesting, the straw at the feed inlet is messy and disordered, which is not conducive to smooth feeding and efficient crushing. At the same time, due to the shape and material characteristics of straw, it is easy for straw to accumulate at the feed inlet, requiring manual and continuous tamping operations. This not only increases the complexity of manual operation, but also increases production costs and safety hazards. To address this, we propose a vibrating feeding device for straw crushers. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a vibrating feeding device for a straw crusher. This utility model solves the problem that traditional straw crushers typically employ mechanical crushing methods. The feeding structure of general straw crushers is relatively simple. Because the straw piles up after harvesting, the straw at the feed inlet is messy and disorderly, hindering smooth feeding and efficient crushing. Furthermore, due to the shape and material characteristics of the straw, it easily accumulates at the feed inlet, requiring continuous manual tamping. This not only increases the complexity of manual operation but also raises production costs and safety hazards.

[0004] This utility model discloses a vibrating feeding device for a straw crusher, comprising a first support frame, with multiple equidistant fixed rods arranged on both sides above the first support frame. A connecting plate is sleeved on the top of each fixed rod, and the multiple connecting plates are fixedly connected to the feeding trough.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-5 As shown, this utility model is a vibrating feeding device for a straw crusher, including a first support frame 1. Multiple equidistant fixed rods 2 are arranged on both sides of the upper part of the first support frame 1. A connecting plate 3 is sleeved on the upper part of each fixed rod 2, and the fixed rods 2 and connecting plates 3 are movably connected, allowing the connecting plates 3 to drive the feeding trough 4 to move vertically. Multiple connecting plates 3 are fixedly connected to the feeding trough 4. A spring 5 is sleeved between the fixed rod 2 and the first support frame 1 and the connecting plate 3, with both ends of the spring 5 fixedly connected to the connecting plate 3 and the first support frame 1, respectively. A vibrating motor 6 is fixedly installed on one side of the upper end of the feeding trough 4. When the vibrating motor 6 is working, it drives the feeding trough 4 to vibrate. Guided by the fixed rods 2 and the connecting plates 3, the feeding trough 4 vibrates vertically. Simultaneously with the vibration of the feeding trough 4, the spring 5 is subjected to force. The feed trough 4 can move stably in the vertical direction by means of the elastic force of the spring 5. A second support frame 7 is provided on one side of the first support frame 1. A motor 8 is provided on the lower side of the second support frame 7. The rotating shaft of the motor 8 passes through the second support frame 7 and is fixedly connected to the active roller shaft 9. A driven roller shaft 10 is provided on the side of the second support frame 7 away from the active roller shaft 9. The active roller shaft 9 and the driven roller shaft 10 are connected by a transmission belt 11. Both ends of the active roller shaft 9 and the driven roller shaft 10 are movably connected to the second support frame 7 through bearings. When the motor 8 is working, the motor 8 drives the active roller shaft 9 to rotate. Through the transmission belt 11, the driven roller shaft 10 also rotates. Through the cooperation between the active roller shaft 9 and the driven roller shaft 10, the transmission belt 11 can transport the straw to be crushed.

[0020] The second support frame 7 is inclined upward.

[0021] The second support frame 7 is provided with a plurality of equally spaced mounting frames 12. Each mounting frame 12 is provided with two symmetrical support rollers 13. The two support rollers 13 are inclined toward the middle of the mounting frame 12 and are located below the conveyor belt 11, so that the support rollers 13 can support the conveyor belt 11, thereby effectively improving the transmission stability of the conveyor belt 11. At the same time, the support rollers 13 are inclined toward the middle of the mounting frame 12, so that the middle of the conveyor belt 11 is concave downward, thereby effectively reducing the probability of straw falling off the conveyor belt 11.

[0022] The lower end of the feed trough 4 is designed as an inverted cone shape. The lower part of the feed trough 4 is connected to the discharge trough 14. The straw inside the feed trough 4 can fall from the discharge trough 14, so that the straw falls directly into the crusher.

[0023] The second support frame 7 is provided with a third support frame 15 at its lower end. The third support frame 15 is located above the conveyor belt 11 and is provided with a feeding hopper 16. The straw to be crushed can fall from the feeding hopper 16 onto the conveyor belt 11. Compared with public personnel directly placing straw on the conveyor belt 11, this can effectively prevent the straw from falling off the conveyor belt 11.

[0024] The second support frame 7 is provided with a brake caster 17 at its bottom, which makes it easier to move and position the second support frame 7.

[0025] Specifically, in this utility model, when the motor 8 is working, the motor 8 drives the active roller shaft 9 to rotate. Through the transmission belt 11, the driven roller shaft 10 also rotates. Through the cooperation between the active roller shaft 9 and the driven roller shaft 10, the transmission belt 11 can transport the straw to be crushed, so that the straw can automatically fall into the feed trough 4. When the vibrating motor 6 is working, the vibrating motor 6 drives the feed trough 4 to vibrate. Through the guide of the connecting plate 3 by the fixed rod 2, the feed trough 4 vibrates in the vertical direction. At the same time as the feed trough 4 vibrates, the spring 5 is stretched and contracted by force. Through the elastic force of the spring 5, the feed trough 4 can move stably in the vertical direction. Through the vibration of the feed trough 4, the straw inside the feed trough 4 can automatically fall into the crusher.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
