Description

Technical Field

[0001] This utility model relates to the field of soil and rock separation technology in land reclamation, specifically to a soil and rock separation device for land reclamation. Background Technology

[0002] Soil-rock separation in land reclamation refers to the pretreatment process in damaged areas such as mining areas and construction sites, where fine soil particles are separated from coarse solid waste such as stones and gravel in the topsoil mixture to be treated, using physical methods such as screening and crushing. Its core purpose is to remove gravel to obtain pure soil for backfilling, while simultaneously recovering stones for engineering filling, thereby improving the quality of reclaimed land, promoting vegetation restoration, and achieving the effective utilization of waste resources. Stone-collecting machines are often used in the soil-rock separation process for separation and collection.

[0003] The aforementioned device lacks a protective and shock-absorbing structure for the stone collection hopper of the existing stone collector. As a result, when the stones are thrown into the collection hopper by the high-speed rotating stone screening belt, the stones thrown into the hopper will first collide with the inner wall of the tail end of the collection hopper before falling into the hopper for collection. After long-term use, the inner wall of the tail end of the collection hopper is prone to denting and deformation, or even being punctured by stones, thus affecting the stone collection effect. Based on the shortcomings of the existing technology, this utility model designs a soil and stone separation device for land reclamation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a land reclamation soil and rock separation device that has the advantages of protecting and reducing the shock of the stone collection bucket of a stone picker.

[0005] This utility model provides the following technical solution: a soil and rock separation device for land reclamation, including a stone sieve bucket, a stone collecting bucket rotatably arranged at the tail of the stone sieve bucket, and a protective mechanism is provided on the inner wall of the tail end of the stone collecting bucket to prevent damage from stone impact.

[0006] The protective mechanism includes a side fixing frame, a protective plate, a buffer pad, fixing holes, a first fixing bolt, a limiting frame, a threaded groove, and a second fixing bolt. The side fixing frame is fixedly connected to both sides of the inner wall of the tail end of the stone collection hopper. The protective plate is inserted into the inside of the side fixing frame. The buffer pad is inserted into the inside of the side fixing frame. The fixing holes are formed through the side fixing frame, the protective plate, and the buffer pad. The first fixing bolt is threaded into the fixing hole. The limiting frame is inserted into the inner side of the top of the side fixing frame. The threaded groove is formed through both sides of the limiting frame and the inner wall of the stone collection hopper. The second fixing bolt is threaded into the threaded groove.

[0007] By setting up a protective plate, stones can be slowed down and intercepted, preventing them from directly impacting the buffer plate or the inner wall of the stone collection hopper, thus reducing the service life of the stone collection hopper. The buffer plate can also cushion the protective plate and reduce the force when impacted. The side fixing frame, fixing holes, and first fixing bolt can limit the movement of the protective plate and the buffer plate.

[0008] As a preferred embodiment of this utility model, a shovel plate is fixedly connected to the inner side of the front end of the stone sieve hopper, an installation groove is provided at the front end of the stone sieve hopper, a first rotating shaft is provided inside the installation groove, a dispersing push plate is fixedly connected to the surface of the first rotating shaft, a first sprocket is fixedly connected to one end of the first rotating shaft, a second rotating shaft is rotatably connected inside the stone sieve hopper, a third rotating shaft is rotatably connected inside the stone sieve hopper, stone sieve tracks are driven on the second and third rotating shafts, a second sprocket is fixedly connected to one end of the third rotating shaft, a first connecting frame is fixedly connected to the top of the front end of the stone sieve hopper, a transmission machine is provided on the first connecting frame, and a transmission chain is driven to both ends of the transmission machine.

[0009] As a preferred embodiment of this utility model, the bottom of the stone collecting hopper is provided with a base frame, the bottom of the base frame is provided with movable wheels, the tail end of the base frame is fixedly connected to a second connecting frame, the top end of the second connecting frame is provided with a hinge arm and connected to the stone collecting hopper, the two sides of the upper surface of the front end of the base frame are fixedly connected to connecting plates, the outer side of the connecting plates is fixedly connected to a first hinge block, the two sides of the stone collecting hopper are fixedly connected to a second hinge block, and a telescopic arm is rotatably hinged between the first hinge block and the second hinge block.

[0010] As a preferred technical solution of this utility model, the limiting frame is clamped and fixedly connected to the top of the protective plate and the buffer pad.

[0011] Fixing holes are provided to facilitate the auxiliary fixing of the protective plate and buffer pad inserted into the side fixing frame.

[0012] As a preferred embodiment of this utility model, the buffer pad is disposed between the protective plate and the inner wall of the stone collection hopper.

[0013] By setting up a buffer plate, the force generated when a stone collides with the protective plate is prevented from being transmitted to the stone collection hopper and causing deformation of the hopper.

[0014] As a preferred embodiment of this utility model, the first fixing bolt is inserted through and connected to both sides of the protective plate and the buffer pad.

[0015] As a preferred technical solution of this utility model, the front stone inlet of the stone collecting hopper is located below the tail end of the stone screening track.

[0016] As a preferred embodiment of this utility model, the transmission chains connected to both ends of the transmission machine are respectively connected to the first sprocket and the second sprocket, and the dispersing push plate is rotatably connected above the shovel plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This land reclamation soil and rock separation device involves inserting a buffer pad into a side fixing frame and fitting it against the inner wall of the tail end of the stone collection hopper. Then, a protective plate is inserted into the side fixing frame and placed in front of the buffer pad. After the protective plate and the buffer pad are fully inserted, the fixing holes on the side fixing frame, the protective plate, and the buffer pad are aligned, and the first fixing bolt is screwed into the fixing holes to fix the buffer pad and the protective plate. At this time, a limiting frame is inserted into the top side fixing frame, so that the bottom of the limiting frame fits against the top of the protective plate and the buffer pad for auxiliary clamping and fixing. Then, two second fixing bolts are screwed into the threaded grooves at both ends of the limiting frame for fixing. This device facilitates the installation of protective plates and buffer pads to protect the stone collection hopper.

[0019] 2. This land reclamation soil and rock separation device uses a protective plate to intercept stones that are quickly thrown into the stone collection hopper during operation. When the stones are about to collide with the inner wall of the hopper, the protective plate can reduce the impact force on the tail end of the stone collection hopper under the buffer of the buffer plate, and allow the stones to fall smoothly into the stone collection hopper for collection. If the protective plate is damaged after long-term use, it is only necessary to remove the limit frame and the first fixing bolt according to the above steps to replace the protective plate. This device is convenient to prevent stones thrown into the stone collection hopper from colliding with the stone collection hopper and causing damage. Attached Figure Description

A second sprocket 109 is fixedly connected to one end of the third rotating shaft 107. A first connecting frame 110 is fixedly connected to the top of the front end of the stone screening hopper 1. A transmission machine 111 is installed on the first connecting frame 110. Transmission chains 112 are driven to both ends of the transmission machine 111. The transmission chains 112 connected to both ends of the transmission machine 111 are respectively connected to the first sprocket 105 and the second sprocket 109. The dispersing push plate 104 is rotatably connected above the shovel plate 101.

[0028] Please see Figure 4The bottom of the stone collection hopper 2 is provided with a base frame 201, and the bottom of the base frame 201 is provided with a moving wheel 202. The tail end of the base frame 201 is fixedly connected to a second connecting frame 203. The top end of the second connecting frame 203 is provided with a hinge arm 204 and connected to the stone collection hopper 2. The two sides of the upper surface of the front end of the base frame 201 are fixedly connected to a connecting plate 208. The outer side of the connecting plate 208 is fixedly connected to a first hinge block 205. The two sides of the stone collection hopper 2 are fixedly connected to a second hinge block 206. A telescopic arm 207 is rotatably hinged between the first hinge block 205 and the second hinge block 206. The front stone inlet of the stone collection hopper 2 is located below the tail end of the stone screening track 108.

[0029] Please see Figure 5 The protective mechanism 3 includes a side fixing frame 301, a protective plate 302, a buffer pad 303, a fixing hole 304, a first fixing bolt 305, a limiting frame 306, a threaded groove 307, and a second fixing bolt 308. The side fixing frame 301 is fixedly connected to both sides of the inner wall of the tail end of the stone collection hopper 2. The protective plate 302 is inserted into the inside of the side fixing frame 301, and the buffer pad 303 is inserted into the inside of the side fixing frame 301. The fixing hole 304 is formed through the side fixing frame 301, the protective plate 302, and the buffer pad 303. The fixing bolt 305 is threaded into the fixing hole 304. The limiting frame 306 is inserted into the inner side of the top of the side fixing frame 301. The threaded groove 307 is opened through both sides of the limiting frame 306 and the inner wall of the stone collection hopper 2. The second fixing bolt 308 is threaded into the threaded groove 307. The limiting frame 306 is clamped and fixedly connected to the top of the protective plate 302 and the buffer pad 303.

The first fixing bolt 305 is inserted through both sides of the protective plate 302 and the buffer pad 303.

[0030] By setting up a protective plate 302, stones can be decelerated and intercepted, preventing them from directly impacting the buffer pad 303 or the inner wall of the tail end of the stone collection hopper 2, thus reducing the service life of the stone collection hopper 2. By setting up a buffer pad 303, the protective plate 302 can be buffered to reduce the force when impacted. By setting up a side fixing frame 301, fixing hole 304 and first fixing bolt 305, the protective plate 302 and buffer pad 303 can be limited. By setting up a limiting frame 306, threaded groove 307 and second fixing bolt 308, the top of the protective plate 302 can be limited to prevent the protective plate 302 and buffer pad 303 from displacing even when locked by the first fixing bolt 305, thus affecting the protection of the stone collection hopper 2.

[0031] Working principle: When a land reclamation soil and rock separation device is used, in the initial state, the shovel plate 101, the first rotating shaft 103, and the dispersing push plate 104 are first set inside the front end of the stone hopper 1. The second rotating shaft 106 and the third rotating shaft 107, installed inside the stone hopper 1, are connected to the stone hopper track 108 and are set inside the stone hopper 1. The outer ends of the first rotating shaft 103 and the third rotating shaft 107 are respectively set with the first rotating shaft 103 and the second sprocket 109, and the two are connected to the transmission machine 111 at the top of the stone hopper 1 through the transmission chain 112, so as to drive the stone hopper track 108 and the dispersing push plate 104 to rotate. The entire equipment is pulled by an agricultural machine. When the soil is being fed in, the stones contained in the soil can be screened. The stone collection hopper 2, which is set behind the stone screening track 108, is rotatably connected to the second connecting frame 203 and the base frame 201 through the hinge arm 204. The second hinge block 206 on the side wall of the stone collection hopper 2 is connected to the connecting plate 208 and the first hinge block 205 on the upper surface of the base frame 201 through the telescopic arm 207, so that the telescopic arm 207 can be used to control the stone collection hopper 2 to flip over for stone unloading. Side fixing frames 301 are set on both sides of the inner wall at the tail end of the stone collection hopper 2, and protective plates 302 and buffer pads 303 are inserted into the side fixing frames 301 to protect the stones that fly into the stone collection hopper 2.

[0032] When it is necessary to install the protective plate 302 and the buffer pad 303 to prevent stones thrown into the stone collection hopper 2 from colliding with and damaging the hopper 2, first insert the buffer pad 303 into the side fixing frame 301 and fit it against the inner wall of the tail end of the stone collection hopper 2. Then, insert the protective plate 302 into the side fixing frame 301 and place it in front of the buffer pad 303. After the protective plate 302 and the buffer pad 303 are fully inserted, align the fixing holes 304 on the side fixing frame 301, the protective plate 302, and the buffer pad 303, and screw the first fixing bolt 305 into the fixing holes 304 to fix the buffer pad 303 and the protective plate 302. At this time, insert the limiting frame 306 into the top side fixing frame 301, so that the bottom of the limiting frame 306 is flush with the protective plate 302 and the buffer pad 303. The top of the 3 is attached and clamped for auxiliary fixation. Then, the two second fixing bolts 308 are screwed into the threaded grooves 307 at both ends of the limiting frame 306 for fixation. During operation, when the stones are quickly thrown into the stone collection hopper 2 and are about to collide with the inner wall of the stone collection hopper 2, the protective plate 302 can intercept the stones. The impact force on the tail end of the stone collection hopper 2 is reduced by the buffer plate 303, and the stones can fall smoothly into the stone collection hopper 2 for collection. If the protective plate 302 is damaged after long-term use, the limiting frame 306 and the first fixing bolt 305 need to be removed and the protective plate 302 replaced according to the above steps. This device is convenient for installing the protective plate 302 and the buffer plate 303 to prevent the stones thrown into the stone collection hopper 2 from colliding with the stone collection hopper 2 and causing damage.
