Description

Technical Field

[0001] This utility model specifically relates to a sorting and crushing device for landscaping waste, belonging to the field of waste crushing technology. Background Technology

[0002] With the advancement of urban greening construction, the output of garden waste is increasing year by year. Crushing and recycling it is an important way to achieve green and circular development. Garden waste crushing equipment plays a key role in converting branches, leaves and other materials into usable materials.

[0003] However, current garden waste sorting and crushing equipment is not suitable for targeted processing based on the characteristics of the waste. During the feeding stage, excessively long branches are prone to entanglement with other materials and getting caught on the edge of the feed inlet, leading to poor feeding or even blockage, reducing processing efficiency. After entering the crushing chamber, long branches are difficult to fix quickly and effectively, and swing wildly due to unstable center of gravity. This not only hinders the normal operation of the crushing rollers and aggravates the wear and tear on the crushing rollers and the internal structure of the equipment, shortening the service life of the equipment, but also causes frequent collisions with the chamber wall, generating huge noise and vibration, interfering with the stable operation of the equipment. Furthermore, long branches may detach from the crushing area due to excessive swinging during the crushing process, causing serious impact injuries to people in the vicinity, posing a significant safety hazard.

[0004] To address the above problems, this application proposes a sorting and crushing device for landscaping waste. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a sorting and crushing device for garden waste. Through innovative design of the crushing and segmenting components, it achieves classified processing of garden waste via dual channels for loose materials and branches. Loose materials enter directly into the crushing rollers for shearing and crushing via an inlet and slide plate; long branches enter through a dedicated inlet, are segmented by a lifting cutter, and then transferred to the crushing rollers for further processing via a sliding roller. Compared to traditional mixed crushing, this solution effectively avoids the risks of material entanglement, impact from swinging long branches, and splashing, significantly improving crushing safety and processing efficiency, and solving the problems mentioned in the background section.

[0006] A sorting and crushing device for landscaping waste includes: a crushing mechanism, comprising a crushing component, a segmenting component, and a discharge component; the crushing component includes a crushing box with a bulk material inlet at the top, and two sets of rotatable crushing rollers installed inside the crushing box; the segmenting component includes a branch inlet with a cutting blade that can be raised and lowered to cut tree branches into segments, and multiple sets of sliding rollers behind the cutting blade for guiding the segmented branches into the crushing box; the discharge component includes two sets of side outlets for lateral discharge of crushed material, and a rotatable switching slide plate inside the crushing box for switching the discharge direction, with multiple sets of sorting holes for sorting the fragments on the surface of the switching slide plate, and a collection tray for collecting the sorted fragments below the switching slide plate.

[0007] In a preferred embodiment, two sets of drive gears are meshed at the rear of the crushing box. The two sets of drive gears are respectively connected to two sets of crushing rollers via rotating shafts. A crushing motor is provided at the rear of one set of drive gears, and the output shaft of the crushing motor is connected to the drive gear. The rear side of the crushing motor is fixedly connected to the crushing box via a fixing plate.

[0008] In a preferred embodiment, a set of feed slide plates is provided above each of the two sets of crushing rollers, and the upper surface of the feed slide plate is an inclined surface. The feed slide plate is fixedly connected to the crushing box.

[0009] In a preferred embodiment, the side feed opening is located on the upper side of the crushing box, a lifting rod is installed above the cutting blade, and a set of guide grooves are respectively provided on both sides of the lifting rod, and the two sides of the lifting rod are slidably connected to the guide grooves.

[0010] In a preferred embodiment, two sets of hydraulic cylinders are installed above the crushing box, and the extension and retraction ends of the two sets of hydraulic cylinders are respectively connected to the lifting rod.

[0011] In a preferred embodiment, the plurality of the sliding rollers are installed at an angle toward the feed slide plate located close to their positions.

[0012] In a preferred embodiment, a switching motor is installed at the rear of the crushing box, and the output shaft of the switching motor is connected to the switching slide plate via a rotating shaft. The other end of the switching slide plate is rotatably connected to the crushing box via a rotating shaft. A guide ring is installed on the side of the crushing box away from the switching motor, and the guide ring is slidably connected to the switching slide plate.

[0013] In a preferred embodiment, the two sets of side material inlets are respectively opened on both sides below the crushing box, and a set of discharge slide plates are respectively installed obliquely in the two sets of side material inlets, and a set of support seats are respectively installed on both sides below the crushing box.

[0014] Beneficial effects:

[0015] 1. By designing crushing and segmentation components, and equipping them with dual channels for bulk material inlet and branch inlet, the system enables the classified processing of garden waste. When processing bulk materials such as leaves, the material is fed into the bulk material inlet and slides directly onto the two sets of crushing rollers via the feed slide, where it is efficiently crushed using the rotational shearing force of the crushing rollers. For long branches, they can be guided through the branch inlet and segmented using a lifting cutter. The segmented branches are then conveyed to the feed slide via the sliding roller and enter the crushing rollers for further crushing. Compared to traditional mixed crushing methods, this design effectively avoids the problem of material entanglement in the crushing components and also prevents the safety hazards of long branches swinging and impacting the equipment and splashing during the crushing process, significantly improving the safety and processing efficiency of the crushing operation.

[0016] 2. By designing a switching component, the crushed material falls uniformly onto the switching slide plate, which guides the material to slide out of the crushing box along the side feed port using its inclined surface. During the material's slide-out process, the sorting holes on the surface of the switching slide plate can automatically screen fine fragments, causing them to fall directly into the collection tray below, achieving efficient separation of coarse and fine materials. When material accumulates at one side feed port, the operator can rotate the switching slide plate to change the inclination direction, allowing subsequent material to be quickly discharged to the other side feed port, effectively avoiding blockages, ensuring a continuous and stable crushing process, and improving material processing efficiency.

[0027] Please see Figure 1 , Figure 4 as well as Figure 5 As shown, the side feed port 31 is opened on the upper side of the crushing box 11, and a lifting rod 23 is installed above the cutting blade 24. A set of guide grooves 26 are opened on both sides of the lifting rod 23, and the two sides of the lifting rod 23 are slidably connected to the guide grooves 26.

[0028] Please see Figures 1-4 As shown, two sets of hydraulic cylinders 22 are installed above the crushing box 11, and the telescopic ends of the two sets of hydraulic cylinders 22 are respectively connected to the lifting rod 23. The hydraulic cylinders 22 can drive the lifting rod 23 to descend along the guide groove 26 through the telescopic ends, thereby driving the cutting blade 24 to perform segmented cutting of long branches.

[0029] Please see Figure 4 As shown, multiple sets of sliding rollers 25 are installed at an angle toward the feeding slide plate 17 located close to them, and the branches after being cut into sections can slide onto the surface of the feeding slide plate 17 through the inclined sliding rollers 25.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] Garden waste enters the crushing box 11 through the bulk material inlet 12 and the branch inlet 21. Bulk materials can slide down through the bulk material inlet 12 via the feed slide plate 17 to the space between two sets of crushing rollers 16. The crushing motor 13 drives the drive gear 14 to rotate. Since the two sets of drive gears 14 mesh with each other, they can drive the two sets of crushing rollers 16 to rotate respectively. After the crushed material reaches the space between the crushing rollers 16, it can be sheared and crushed by the rotating crushing rollers 16. Branches can be introduced through the branch inlet 21. During the introduction process, the hydraulic cylinder 22 can be activated to drive the lifting rod 23 to descend along the guide groove 26, driving the cutting blade 24 to cut the long branches into sections. The cut branches can then be guided by the inclined sliding roller 25. The material is fed into the infeed slide plate 17 and then falls between the crushing rollers 16 for crushing. After crushing, the material falls onto the inclined switching slide plate 35 and slides. Smaller pieces fall into the collection tray 32 below through the sorting holes 36, while larger pieces slide down the inclined surface of the switching slide plate 35 to the discharge slide plate 34. The material then slides through the discharge slide plate 34 to the side discharge port 31 for discharge. When there is a large accumulation at one discharge position, the discharge direction can be switched. The switching motor 38 is started to drive the switching slide plate 35 to rotate to the opposite inclined state, so that its other end contacts the discharge slide plate 34 on the other side and connects with the side discharge port 31 on the other side. When the switching slide plate 35 rotates, it can rotate along the path of the guide ring 37 to maintain stability, thereby realizing the switching of the material discharge direction.
