Description

Technical Field

[0001] This utility model relates to the field of wood sorting technology, and in particular to a wood sorting and feeding structure. Background Technology

[0002] Timber is a widely used material in the decoration and construction industries. Timber raw materials are usually processed into various boards and other products for wider use. However, timber raw materials come in different diameter grades. Without sorting and screening, not only will the timber processing machine be damaged, but the timber raw materials cannot be classified and used according to their diameter grade, which will seriously affect the use of the timber raw materials and easily lead to the phenomenon of using large timbers for small purposes. Therefore, sorting and screening should be carried out in the early stage of timber raw material processing.

[0003] In the prior art, CN217616135U discloses an automatic sorting device for wood raw materials, including a frame, a conveyor frame connected to the frame, a conveyor roller connected to the conveyor frame, a conveyor belt sleeved on the conveyor roller, a feeding platform and a discharging platform connected to both ends of the conveyor belt on the frame, a plurality of hangers connected to the frame above the conveyor belt, the height of the hangers gradually decreasing along the conveying direction of the conveyor belt, a screening mechanism connected to the bottom of the hangers, and a receiving trough provided below the conveyor belt corresponding to the screening mechanism.

[0004] However, when the above device is in operation, the wood rolls onto the conveyor belt through the feeding platform. There is no corresponding straightening structure designed for the wood. When the wood deviates, the telescopic cylinder cannot push the wood properly, causing the wood to fall into the corresponding receiving trough accurately, which reduces the practicality of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Reference Figures 1-5 A wood sorting and unloading structure includes a sorting device housing 1. The structure is characterized by a feed pipe 2 fixed to the top of the housing 1, a motor 3 fixed to one side of the housing 1, a first threaded rod 4 installed at the output end of the motor 3, a first pulley 5 fixed at the end of the first threaded rod 4, a belt 6 installed on the outer side of the first pulley 5, a second pulley 7 installed at the other end of the belt 6, a second threaded rod 8 coaxially fixed to the second pulley 7, a push plate 10 positioned between the second threaded rod 8 and the first threaded rod 4, and sliders 9 fixed on both sides of the push plate 10. The two sliders 9 are threadedly connected to the first threaded rod 4 and the second threaded rod 8, respectively. The push plate 10 is moved by the motor 3 and the first threaded rod 4, which simultaneously pushes the wood and corrects any deviation in the wood's orientation.

[0024] Hollow rods 11 are fixed at the four corners of one side of the push plate 10. Springs 12 are installed inside the hollow rods 11. One end of the springs 12 is fixedly connected to the hollow rods 11 and the other end is fixedly connected to a movable rod 13. A buffer plate 14 is fixed at the end of the movable rod 13. The impact of the wood is buffered by the buffer plate 14 and the springs 12, etc., to reduce the damage to the device.

[0025] The inner bottom surface of the sorting device housing 1 is provided with screen holes 15 at equal intervals, and the width of the screen holes 15 gradually increases from left to right. As the wood is pushed from left to right, the width of the screen holes 15 gradually increases from left to right, so that the wood falls into the corresponding screen holes 15, thus completing the screening of the wood.

[0026] The bottom of the sorting device housing 1 is fixed with a base 16. The base 16 is equipped with a receiving box 17, which is located directly below the screening hole 15. Limiting blocks 18 are provided on both sides of the receiving box 17, and the limiting blocks 18 are fixedly connected to the base 16. The limiting blocks 18 restrict the receiving box 17 to prevent it from shifting due to impact from the wood.

[0027] The two sides of the housing 1 of the sorting device are provided with guide grooves 19, and the guide grooves 19 are matched with the slider 9. By setting the guide grooves 19, the slider 9 can move smoothly, thereby improving the stability of the device operation.

[0028] In this invention, each piece of wood is placed into the feed pipe 2. Under the action of the feed pipe 2, the wood rolls to the left side of the sorting device housing 1. It is buffered by the buffer plate 14, the movable rod 13, the hollow rod 11 and the spring 12. Then the motor 3 is turned on, and the motor 3 drives the first threaded rod 4 to rotate. The first threaded rod 4 drives the second threaded rod 8 to rotate through the first pulley 5, the belt 6 and the second pulley 7. The push plate 10 has sliders 9 fixed on both sides. The two sliders 9 are threadedly connected to the first threaded rod 4 and the second threaded rod 8 respectively. The push plate 10 and the buffer plate 14 push the wood and correct its deviation at the same time. Since the width of the screen hole 15 gradually increases from left to right, when the wood moves to the screen hole 15 that matches perfectly, it falls into the receiving box 17 below. The receiving box 17 is provided with limit blocks 18 on both sides. The limit blocks 18 are fixedly connected to the base 16. The limit blocks 18 can prevent the receiving box 17 from shifting.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
