[0002] When some solid waste (such as construction waste) is processed, it will be transported to a garbage crushing station for crushing. The crushing station includes a jaw crusher, a screen and a conveyor belt. After the solid waste is placed in the jaw crusher, the reciprocating motion of the jaw crusher squeezes the solid waste to crush it. Some special solid waste will have requirements for the particle size after crushing, which makes it easier to recycle. Among them, the crushed solid waste will fall into the screen, and the screen will select and collect the materials with the required particle size, while the larger particles cannot pass through the screen and will roll onto the conveyor belt and be transported to one side of the crushing station by the conveyor belt for accumulation.

[0003] The existing screen is tilted so that the larger-sized materials slide from the top of the screen to the conveyor belt under the action of gravity, and the materials that meet the particle size requirements fall below the screen through the screen holes on the screen. However, some larger-sized materials will get stuck in the screen holes and cause blockage, affecting the discharge of materials that meet the particle size requirements, causing some materials that meet the particle size requirements to roll down from the screen together with the larger-sized materials and fall on the conveyor belt to be transported to one side of the crushing station for accumulation, thereby affecting the screening effect.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships that are based on the positions or location relationships when the product is in normal use.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] The utility model provides a frame mobile crushing station, referring to Figure 1 and Figure 2 The frame mobile crushing station includes a frame 1, a crushing group 2, a linear vibrating screen 3 and a material conveyor belt 4. The crushing group 2, the linear vibrating screen 3 and the material conveyor belt 4 are all installed on the frame 1, so the installation cycle is short and the transfer and follow-up are fast. The crushing group 2 is used to crush the solid waste materials twice. The materials after the first crushing will fall into the linear vibrating screen 3 for screening. The materials with the required particle size will fall directly into the material conveyor belt 4 after screening and be transported for collection; and the materials with particle size that do not meet the requirements will be screened and crushed for the second time through the crushing group 2. The materials after the second crushing will fall into the material conveyor belt 4 for transportation.

[0030] The crushing group 2 includes a first crusher 21 and a second crusher 22. The volume of the first crusher 21 is larger than that of the second crusher 22, and the particle size crushed by the first crusher 21 is larger than that of the second crusher 22. Therefore, the first crusher 21 performs the first crushing on the material, and the second crusher 22 crushes the crushed material again. Since the jaw crusher has the advantages of low energy consumption, high crushing ratio, and good crushing effect, it is preferred in this embodiment that both the first crusher 21 and the second crusher 22 are jaw crushers.

[0031] The first crusher 21 is located above the linear vibrating screen 3 and fixedly mounted on the frame 1, and the materials after the first crushing can fall into the linear vibrating screen 3 for screening. The second crusher 22 is fixedly mounted on one side of the linear vibrating screen 3 to receive the materials with larger particle size that have not passed through the linear vibrating screen 3 for secondary crushing.

[0032] Reference Figure 1 and Figure 2The linear vibrating screen 3 is tilted on the frame 1, and the higher side of the linear vibrating screen 3 is located below the first crusher 21; the lower side of the linear vibrating screen 3 is close to the second crusher 22. In this way, the material crushed by the first crusher 21 can automatically roll down under the action of gravity after falling on the linear vibrating screen 3.

[0033] Combination Figure 1 Reference Figure 2 and Figure 3 The linear vibrating screen 3 includes a bottom frame 31 and a hopper 32. The hopper 32 is tilted at the top of the bottom frame 31, that is, the higher side of the hopper 32 is located below the first crusher 21; the lower side of the hopper 32 is close to the second crusher 22. The bottom frame 31 is close to the second crusher 22, and the corresponding feed port of the hopper 32 is also tilted, and a material outlet is provided at the bottom of the hopper 32, and the material that meets the particle size requirements will fall onto the unloading conveyor belt 4 through the material outlet.

[0034] A screen 33 is fixedly installed at the feed port of the hopper 32. The inclination direction of the screen 33 is the same as that of the hopper 32, and the screen 33 is located inside the hopper 32, so that the side wall of the hopper 32 can block the material falling on the screen 33. The screen 33 is provided with a plurality of screen holes at intervals, and the material that meets the particle size requirements will pass through the screen holes and fall into the hopper 32 and be discharged from the material outlet. The maximum width at the discharge port of the second crusher 22 is smaller than the aperture of the screen hole, so the material crushed by the second crusher 22 will meet the particle size requirements after being discharged.

[0035] Reference Figure 3 and Figure 4 A rotating shaft 34 is rotatably provided on the hopper 32, and the rotating shaft 34 passes through the hopper 32 and is located below the screen 33. A driving motor is provided on the bottom frame 31, and the driving motor is connected to the rotating shaft 34 through a belt and drives the rotating shaft 34 to rotate. A knocking assembly 35 is provided on the rotating shaft 34, and the knocking assembly 35 rotates synchronously with the rotating shaft 34 and is suitable for intermittently knocking the screen 33, so that the material stuck on the screen hole is vibrated and separated from the screen hole without blocking the screen hole.

[0036] Combination Figure 3 Reference Figure 4 and Figure 5The knocking assembly 35 includes a collar 36 and a rubber rod 37. The collar 36 is sleeved on the rotating shaft 34 and rotates synchronously with the rotating shaft 34. A docking post is welded on the outer wall of the collar 36. One end of the rubber rod 37 is sleeved on the docking post and fixed to the docking post by a wire. The length of the rubber rod 37 is greater than the straight-line distance from the collar 36 to the bottom of the screen 33. Therefore, as the rotating shaft 34 rotates, the rubber rod 37 will have an interference fit with the screen 33 and intermittently knock the screen 33, so that materials with larger particle sizes are not easy to block the screen holes. After knocking the screen 33, the rubber rod 37 can be squeezed and bent under the action of its own elasticity to pass through the screen 33.

[0037] Among them, the outer wall of the rubber rod 37 is provided with multiple deformation ring grooves, and the multiple deformation ring grooves are arranged at intervals along the extension direction of the rubber rod 37, so that the rubber rod 37 has a deformation bending space after bending, and is more likely to bend and pass through the screen 33 after being squeezed by the screen 33.

[0038] Combination Figure 1 Reference Figure 2 and Figure 3 , the side of the bottom frame 31 close to the second crusher 22 is hingedly connected to the frame 1 through a hinge shaft, and the side of the bottom frame 31 away from the second crusher 22 is hingedly connected to a hydraulic cylinder 11. The hydraulic rod of the hydraulic cylinder 11 is hingedly connected to the bottom frame 31; the bottom of the cylinder body of the hydraulic cylinder 11 is hingedly connected to the frame 1, and then the hydraulic cylinder 11 can drive the higher side of the entire linear vibrating screen 3 to swing, so that the material on the screen 33 can also move back and forth to a certain extent, increasing the time and path of the material passing through the screen 33, and can effectively screen the material that meets the particle size requirements. In order to ensure that the hydraulic cylinder 11 stably supports and connects the bottom frame 31, the present embodiment preferably arranges three hydraulic cylinders 11 at intervals.

[0039] A circulating conveyor belt 12 is arranged between the linear vibrating screen 3 and the second crusher 22. The circulating conveyor belt 12 is installed on the frame 1. Under the action of the circulating conveyor belt 12, materials that do not pass through the sieve holes can enter the second crusher 22 for crushing more accurately and conveniently.

[0040] An extension plate 38 is integrally formed on the side of the screen 33 close to the circulating conveyor belt 12, and the extension plate 38 protrudes from the linear vibrating screen 3. No matter at what angle the linear vibrating screen 3 rotates, the extension plate 38 is always located directly above the side of the circulating conveyor belt 12 close to the linear vibrating screen 3, so that the material that does not pass through the screen hole can fall accurately on the circulating conveyor belt 12.

[0041] Combination Figure 1 Reference Figure 2 and Figure 3Two baffles 13 are symmetrically arranged at intervals on the top of the circulating conveyor belt 12, and the extension plate 38 is located between the two baffles 13, so that the materials falling on the circulating conveyor belt 12 are not easy to collapse outside the circulating conveyor belt 12. Among them, the size of the feed opening of the second crusher 22 is smaller than the width of the circulating conveyor belt 12, and each baffle 13 is fixed with an inclined guide plate 14 at one end away from the extension plate 38 along the conveying direction of the circulating conveyor belt 12. The distance between the two inclined guide plates 14 and one end of the second crusher 22 is smaller than the size of the feed opening of the second crusher 22, so that all the materials on the circulating conveyor belt 12 can be accurately transported to the second crusher 22.

[0042] The unloading conveyor belt 4 is located below the linear vibrating screen 3 and the second crusher 22 to receive and convey the materials with the required particle size. The unloading conveyor belt 4 is obliquely installed on the frame 1. The conveying direction of the unloading conveyor is from the linear vibrating screen 3 to the second crusher 22. The height of the unloading conveyor belt 4 close to the linear vibrating screen 3 is higher than the height of the unloading conveyor belt 4 close to the second crusher 22. Therefore, when the materials are conveyed on the unloading conveyor belt 4, they will also roll along the conveying direction to reduce energy consumption.

[0043] The implementation principle of a frame mobile crushing station in the embodiment of the present application is as follows: solid waste materials are first directly transported to the first crusher 21 for crushing, and the crushed materials will fall on the screen 33, and the materials that meet the particle size requirements will fall into the hopper 32 through the screen holes and pass through the hopper 32 to fall on the unloading conveyor belt 4. In this process, the rubber rod 37 will intermittently knock the screen 33 as the rotating shaft 34 rotates to knock down the materials stuck on the screen holes, ensuring the unobstructed screen holes on the screen 33; at the same time, the hydraulic cylinder 11 will also drive the linear vibrating screen 3 to swing, so that the materials on the screen 33 can also move back and forth to a certain extent, increasing the time and path of the materials passing through the screen 33, and can effectively screen the materials that meet the particle size requirements.

[0044] Materials with larger particle sizes and that do not pass through the sieve holes will be directly transported to the second crusher 22 through the circulating conveyor belt 12. The second crusher 22 can more easily crush the materials crushed by the first crusher 21, and the maximum discharge port width of the second crusher 22 is smaller than the aperture of the sieve holes. Therefore, the materials crushed by the second crusher 22 can be directly discharged to the discharge conveyor belt 4.

[0045] The above embodiment only expresses one implementation mode of the present disclosure, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the utility model concept of the present disclosure, which all belong to the protection scope of the present disclosure.
