[0001] The utility model relates to the technical field of particle transportation, and specifically relates to a transportation device for particles of different sizes. Background Art

[0002] Wood particles are used as important accessories in the construction process. In most cases, they are cylindrical wood particles after cutting large round logs. However, in most cases, the sizes of these wood particles are not the same, and they often need to be screened before transportation.

[0003] The transportation of wood particles is generally carried out by moving and carrying with a transportation frame or conveying with a conveyor belt. During the transportation of wood particles, manual picking is required for cooperation, and then subsequent use is carried out.

[0004] Usually, screening is required before transporting wood particles. In most cases, manual screening with a sieve is needed. This process takes a long time and consumes a large amount of manpower, and it is very inconvenient for long-term operation; during the screening process, some smaller wood particles are likely to accumulate and cause the sieve to be blocked. After being blocked, workers need to manually remove the blockage. Content of the Utility Model

[0025] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will provide a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0026] Embodiment 1

[0027] Referring to Figures 1-3 , which is the first embodiment of the present utility model, a transportation device for particles of different sizes is provided, including a transportation frame 1. The transportation frame 1 is a square frame, and the connection with the screening frame 21 has the same opening as the screening material outlet. The bottom side of the transportation frame 1 is fixedly connected to the ground, and the size of the transportation frame 1 is larger than that of the screening frame 21. A transportation plate 11 is arranged inside the transportation frame 1. The transportation plate 11 is an inclined plate with an inclination angle, which is used to transport the screened wood particles to the next position. A sliding groove 12 is opened on one side of the transportation frame 1, and the sliding groove 12 is used in cooperation with a sliding block 29 to limit the movement direction and relative position of the screening frame 21;

[0028] It also includes a screening structure arranged on one side of the transportation frame 1;

[0029] The screening structure includes a screening frame 21 movably connected to the transportation frame 1. The screening frame 21 is a square frame and is slidably connected to the transportation frame 1 through a sliding block 29. A sieve plate 22 fixed in the screening frame 21. The sieve plate 22 is an inclined plate with the same inclination angle as the transportation plate 11, and the sieve holes with gradually decreasing diameters are arranged from top to bottom on the sieve plate 22. The number and intervals of the sieve plates 22 can be reasonably allocated according to the types and quantities of the screening materials. An insertion plate 23 movably connected in the screening frame 21. The insertion plate 23 is inserted into the position between the screening frame 21 and the transportation frame 1, which is used to limit the materials in the screening frame 21 during the screening stage. A dial block 24 fixed on the screening frame 21. The dial block 24 is fixed on the back of the screening frame 21. A spring 25 fixed on the dial block 24. The other end of the spring 25 is fixed on the mounting frame 28, which is used to rebound the screening frame 21. A cam 26 arranged on one side of the dial block 24. A first motor 27 arranged on one side of the cam 26. The first motor 27 is used to drive the cam 26 to rotate. During the rotation of the cam 26, the dial block 24 will be toggled, so that the entire screening frame 21 is displaced, and the spring 25 is used to rebound the screening frame 21 and increase the screening efficiency of the screening frame 21. A sliding block 29 fixed on the screening frame 21.

[0030] An outer side of the first motor 27 is provided with a mounting frame 28. The mounting frame 28 is fixed on the ground and is used to limit the cam 26. The spring 25 is fixedly connected to the mounting frame 28.

[0031] The bottom side of the screening frame 21 is fixedly connected with a directional wheel, which can only move horizontally and is used to reduce the ground friction force received by the screening frame 21 during shaking, convert sliding friction into rolling friction, and can improve the ability of the screening frame 21 to follow the movement of the shifting block 24 and reduce the influence of the friction force on the screening frame 21.

[0032] A square hole is formed in the bottom side of the screening frame 21 for discharging the finally screened particles, and a cleaning structure is arranged in the screening frame 21.

[0033] During use, when screening, the insertion plate 23 needs to be inserted into the screening frame 21 first, and then the material to be screened is poured onto the top of the screening frame 21. When adding the material, the first motor 27 needs to be started. The first motor 27 drives the cam 26 to rotate, and the rotation of the cam 26 will push against the shifting block 24. Since the shifting block 24 is fixed on the screening frame 21, the screening frame 21 will follow the displacement of the shifting block 24. When the shifting block 24 is pushed open by the cam 26, the spring 25 will also be compressed. When the shifting block 24 moves to a certain position, the spring 25 is compressed to the limit. At this time, the spring 25 rebounds and transports the shifting block 24 and the screening frame 21 back to the original position. Due to inertia, the screening frame 21 will cross the initial position and be closer to the cam 26. Then the cam 26 pushes the shifting block 24 open again to complete the movement cycle. During the stretching and contracting process of the spring 25, the movement amplitude of the screening frame 21 will be increased, thereby improving the screening efficiency.

[0034] The wood particles will be screened by the sieve plate 22 in turn. Those remaining on the uppermost side are all wood particles with larger pore diameters, and they become smaller towards the bottom. When the wood particles can pass through the lowermost sieve plate 22, if the wood particles are needed, a feed hopper can be added to the bottom side of the screening frame 21, and if not, they can be directly discarded.

[0035] After screening is completed, open the insertion plate 23 and transport the screened wood particles through the inclined sieve plate 22 and the transport plate 11.

[0036] Embodiment 2

[0037] Refer to Figures 1-4 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the cleaning structure includes a central plate 31 arranged outside the screening frame 21. A threaded hole that can be threadedly connected with a lead screw 32 is arranged in the central plate 31. The lead screw 32 threadedly connected in the central plate 31, a second motor 33 arranged on the lead screw 32. The second motor 33 is a motor that can rotate forward and backward at a certain period. The second motor 33 is fixed on the screening frame 21 through an external round sleeve. An installation seat 34 arranged on the lead screw 32. The lead screw 32 is rotatably connected with the installation seat 34, and the installation seat 34 is fixed on the screening frame 21.

[0038] A round rod 35 is fixedly connected to the central plate 31. A hole is formed in the screening frame 21, and its shape is the same as the displacement path of the round rod 35, and the positions are all directly below each layer of sieve plate 22. A rotating sleeve 36 is rotatably connected to the round rod 35. A cleaning brush 37 is fixedly connected to the outer side of the rotating sleeve 36. The cleaning brush 37 is a hard conical block and can be inserted into the sieve holes of the sieve plate 22 to extrude the blockages in the sieve holes. And when the rotating sleeve 36 moves along with the round rod 35, since the cleaning brush 37 is inserted into the sieve holes of the sieve plate 22, the cleaning brush 37 will be limited, resulting in the rotation of the rotating sleeve 36 on the round rod 35 during the displacement of the rotating sleeve 36, causing the next set of cleaning brushes 37 to enter the next row of sieve holes for continuous cleaning.

[0039] During the use process, first, as long as the screening frame 21 is in the screening stage, the second motor 33 will be continuously started. The second motor 33 will rotate forward and backward periodically, thereby driving the lead screw 32 to rotate forward and backward, driving the central plate 31 to reciprocate along the lead screw 32, and driving the round rod 35 located on the central plate 31 to move along with the central plate 31. The round rod 35 is in the side path holes formed in the screening frame 21. During the displacement of the round rod 35 along with the central plate 31, the rotating sleeve 36 rotatably connected to the outer side of the round rod 35 will also move along with the round rod 35. During the displacement of the rotating sleeve 36, the cleaning brush 37 located on the outer side of the rotating sleeve 36 will enter the sieve holes of the sieve plate 22 to push out the wood particles blocked in the sieve holes, so that the blocked wood particles return to the upper layer for re-screening. And as the central plate 31 moves, the cleaning brush 37 will be limited in the sieve holes, but the central plate 31 will not stop due to the limitation of the cleaning brush 37, so it will drive the rotating sleeve 36 to rotate, and the rotation of the rotating sleeve 36 will cause the next set of cleaning brushes 37 to enter the next set of sieve holes, thus forming a situation where there is always a cleaning brush 37 entering the sieve holes to clean the blockages, ensuring that the sieve holes remain unblocked during the screening process.

[0040] The remaining structure is the same as that of Embodiment 1.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
