[0001] This utility model relates to the field of shotcrete preparation technology, specifically to a stone processing device for shotcrete. Background Technology
[0002] Shotcrete is concrete sprayed from a spray gun to form a protective layer on a structure. It typically includes cement, sand, gravel / stone dust, water, and admixtures. Gravel is one of the most commonly used aggregates; after crushing and processing, gravel / stone dust can be obtained.
[0003] Shotcrete is commonly used in tunnel engineering: a crushing and processing plant is built near the construction site to crush and process tunnel muck (which contains a large number of stones) to obtain gravel / stone dust, which is used as one of the raw materials for shotcrete, realizing waste utilization and reducing the amount of construction waste generated.
[0004] In traditional technology, tunnel muck is screened using an inclined vibrating chamber. Tunnel muck is fed into one end of the vibrating chamber, and the screened stones are discharged through the other end. When multi-stage screening is required, multiple transport vehicles cannot simultaneously gather at the same end of the vibrating chamber to load stones of different sizes. Summary of the Invention

[0009] As a further optimized solution of the utility model, the end plate is erected at the left end of the accommodation cavity; the bottom edge of the end plate is hermetically and fixedly connected to the left edge of the first bottom plate, and the two side edges of the end plate are respectively hermetically and fixedly connected to the two side plates; the two side edges of the first bottom plate are respectively hermetically and fixedly connected to the two side plates; the two side edges of the second bottom plate are respectively hermetically and fixedly connected to the two side plates.
[0010] As a further optimized solution of the utility model, the silo module further includes an extension block, the extension block is fixedly connected to the outer side wall of the side plate of the vibrating silo; the support module includes a support leg and a connecting block arranged at the top end of the support leg, and a vertical support spring is installed between the connecting block and the extension block.
[0011] As a further optimized solution of the utility model, there is an activity gap between the vibrating silo and the connecting block.
[0012] As a further optimization of this utility model, a cross brace spring is installed in the movable gap.
[0013] As a further optimization of this utility model, the bottom surface of the extension block is provided with a first insertion hole, the top surface of the connecting block is provided with a second insertion hole adapted to the first insertion hole, and the top and bottom ends of the vertical support spring are respectively inserted into the first insertion hole and the second insertion hole.

[0018] (3) Tunnel muck first passes through small mesh and then through large mesh, enabling three-stage screening through a single-layer screen assembly, effectively reducing impact damage (in traditional technology, three-stage screening requires two layers of screens, i.e., stones fall and impact the first screen, and then some stones pass through the first screen and fall and impact the second screen, meaning both screens are damaged by the impact of the stones, requiring frequent replacement of both screens). In this invention, only the first screen is impacted by the stones, while the stones slide / roll on the second screen instead of impacting, so only the first screen needs to be replaced periodically, thereby reducing the operation and maintenance costs of this invention.
[0019] (5) The first screen can be replaced separately, further reducing the operation and maintenance costs of the utility model. Attached Figure Description

Detailed Implementation
[0022] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows: Reference Figures 1-2 This embodiment provides a stone processing device for shotcrete, including a silo module 1, a support module 2 movably connected to the silo module 1, and a drive module 3 for driving the silo module 1 to vibrate. The drive module 3 is used to drive the silo module 1 to vibrate; the support module 2 is used to elastically support the vibrating silo module 1; the vibration of the silo module 1 is used to screen out stones (including blocks and pebbles) of different sizes.
[0023] Reference Figures 1-3 , Figure 6 The storage module 1 includes a vibrating chamber 11, which includes side plates 111, a first bottom plate 312, a second bottom plate 322, a screen assembly 114, and an end plate 115. Two side plates 111 are vertically positioned. A receiving cavity 110 for accommodating stones is provided between the two side plates 111. The first bottom plate 312 and the second bottom plate 322 are both fixedly installed at the bottom of the receiving cavity 110.
[0024] Reference Figure 6 The first base plate 312 is inclined upward on the left and downward on the right. When a stone is dropped into the top left of the receiving cavity 110, it falls onto the first base plate 312. Since the vibrating chamber 11 can vibrate as a whole, the first base plate 312 and the stone also vibrate, allowing the stone to slowly slide downward to the right along the top surface of the first base plate 312.
[0025] Reference Figure 6 The second base plate 322 is inclined downward at its left end and upward at its right end; the second base plate 322 is located below the first base plate 312; the right edge of the second base plate 322 is sealed to the middle of the bottom surface of the first base plate 312 (e.g., by welding). A pebble first falls onto the right end of the upper surface of the second base plate 322. Because the vibrating chamber 11 can vibrate as a whole, both the second base plate 322 and the pebble vibrate, allowing the pebble to slowly slide downward and to the left along the top surface of the second base plate 322.
[0026] Reference Figure 6 The screen assembly 114 is inclined upward on the left and downward on the right; the screen assembly 114 is positioned above the first base plate 312. Stones inserted into the top left of the receiving cavity 110 fall onto the screen assembly 114. Because the vibrating chamber 11 can vibrate as a whole, both the screen assembly 114 and the stones vibrate, allowing the stones to slowly slide downward and to the right along the top surface of the screen assembly 114.
[0027] Reference Figure 6 A first channel is provided between the screen assembly 114 and the first base plate 312, and a second channel is provided between the first base plate 312 and the second base plate 322; the first base plate 312 is provided with a connecting hole 1121, the top end of the connecting hole 1121 is connected to the middle of the first channel, and the bottom end of the connecting hole 1121 is connected to the top end of the second channel.
[0028] Reference Figure 6 The screen assembly 114 includes a first screen 1141 and a second screen 1142. The mesh size of the first screen 1141 is smaller than that of the second screen 1142. The first screen 1141 is located above and to the left of the connecting hole 1121. The second screen 1142 is located above and to the right of the connecting hole 1121.
[0029] Reference Figure 6 The stones, fed into the top left end of the receiving cavity 110, first fall onto the screen assembly 114 and slowly move downwards along it. As the stones pass above the first screen 1141, some pass through the mesh and fall onto the left half of the upper surface of the first base plate 312. They then continue moving downwards and to the right along the first base plate 312, passing through the connecting hole 1121 and falling onto the right end of the upper surface of the second base plate 322. They then continue moving downwards and to the left along the second base plate 322 until they are discharged from the left end of the vibrating chamber 11. As the stones pass above the second screen 1142, some pass through the mesh and fall onto the right half of the upper surface of the first base plate 312. They then continue moving downwards and to the right along the first base plate 312 until they are discharged from the right end of the vibrating chamber 11. The remaining larger stones (i.e., stones that cannot pass through the mesh of the first screen 1141 or the mesh of the second screen 1142) continue to move downward to the right along the screen assembly 114 until they are discharged from the right end of the vibrating chamber 11.
[0030] Reference Figure 6 The first and second channels are connected in an "I" shape, thereby achieving the separation of two parts of stones (the stones that fall through the first screen 1141 mesh and the stones that fall through the second screen 1142 mesh), and thus achieving screening.
[0031] Reference Figure 6, the bottom openings of the second channel and the first channel are respectively arranged at the left and right ends of the vibrating bin 11. The user parks the first transfer vehicle 4 and the second transfer vehicle 5 respectively under the left and right ends of the vibrating bin 11, so as to achieve the承接 and loading of the two parts of stones (the stones falling through the mesh holes of the first screen 1141 are discharged from the left end of the vibrating bin 11 and fall into the hopper of the first transfer vehicle 4; the stones falling through the mesh holes of the second screen 1142 are discharged from the left end of the vibrating bin 11 and fall into the hopper of the second transfer vehicle 5. The user directly drives the first transfer vehicle 4 / second transfer vehicle 5 to transport the corresponding stones to the required position, which can achieve convenient transfer).
[0032] Refer to Figure 6 And Figure 8 , the screen assembly 114 further includes an installation frame 1143 in the shape of a Chinese character "ri", and the installation frame 1143 is provided with two rectangular holes. The first screen 1141 and the second screen 1142 are respectively installed in the two rectangular holes. The four sides of the first screen 1141 are respectively detachably connected to the installation frame 1143 (for example, detachably connected by a pressing strip and bolts), and the four sides of the second screen 1142 are respectively fixedly connected to the installation frame 1143 (for example, fixedly connected by welding). The outer side wall of the installation frame 1143 is fixedly connected to the side plate 111 and the end (for example, fixedly connected by bolts or by welding).
[0033] Refer to Figure 3 And Figure 6 , the end plate 115 is erected at the left end of the accommodating cavity 110; the bottom edge of the end plate 115 is hermetically and fixedly connected to the left edge of the first bottom plate 312 (for example, connected by welding), so as to prevent stones from leaking out from the connection position between the end plate 115 and the first bottom plate 312. The two side edges of the end plate 115 are respectively hermetically and fixedly connected to the two side plates 111 (for example, connected by welding) to prevent stones from leaking out. The two side edges of the first bottom plate 312 are respectively hermetically and fixedly connected to the two side plates 111 (for example, connected by welding) to prevent stones from leaking out. The two side edges of the second bottom plate 322 are respectively hermetically and fixedly connected to the two side plates 111 (for example, connected by welding) to prevent stones from leaking out.
[0034] Refer to Figure 6 And Figure 7The connecting hole 1121 has a strip-shaped perforation structure, thereby preventing stones from moving from the left half to the right half of the first base plate 312, thus preventing the two parts of stones from mixing. Since the stones (i.e., tunnel muck containing stones of different volumes) put in through the top left end of the receiving cavity 110 first pass through the first screen 1141 and then through the second screen 1142, and the mesh size of the first screen 1141 is smaller than that of the second screen 1142 (unlike the traditional technology where the stones pass through a larger mesh first and then through a smaller mesh later), the stones pass through the first screen 1141 and then through the second screen 1142. This invention employs a multi-layer screening solution using small mesh openings. The stones pass through small mesh openings first, then large mesh openings, enabling three-stage screening via a single-layer screen assembly 114. This effectively reduces impact damage (in traditional three-stage screening, two layers of screens are required; stones fall and impact the first screen, then some pass through and fall onto the second screen, resulting in impact damage to both screens and frequent replacement). In this invention, only the first screen 1141 is impacted by falling stones; the stones slide / roll on the second screen 1142 instead of impacting. Therefore, only the first screen 1141 needs periodic replacement, reducing the operating and maintenance costs of this invention.
[0035] Reference Figure 8 The screen assembly 114 also includes a bottom support reinforcing rod 1144, which is located below the mounting frame 1143. The top two ends of the bottom support reinforcing rod 1144 are fixedly connected to the bottom two ends of the mounting frame 1143 (e.g., by bolts or welding). The bottom support reinforcing rod 1144 is located below the first screen 1141, and the first screen 1141 is pressed onto the bottom support reinforcing rod 1144. The bottom support reinforcing rod 1144 assists the first screen 1141 in bearing the weight of the stones, thus improving the service life of the first screen 1141. The bottom support reinforcing rod 1144 is located below the second screen 1142, and the second screen 1142 is pressed onto the bottom support reinforcing rod 1144. The bottom support reinforcing rod 1144 assists the second screen 1142 in bearing the weight of the stones, thus improving the service life of the second screen 1142.
[0036] Reference Figure 9A top plate 116 is provided at the top of the receiving cavity 110. The two edges of the top plate 116 are fixedly connected to the tops of two side plates 111 (e.g., by welding or by bolts). Dust is generated when stones vibrate and are conveyed within the receiving cavity 110. The top plate 116 is used to block dust, preventing it from flowing out of the receiving cavity 110 and thus reducing environmental pollution. A feeding port is provided at the left end of the top plate 116, and a cover plate 1161 that can be opened and closed is provided at the feeding port. One end of the cover plate 1161 is rotatably connected to the top plate 116 (e.g., by a hinge), and the other end is detachably connected to the top of the end plate 115 (e.g., by a spring-loaded buckle). When feeding is required, the user can manually open the cover plate 1161; after feeding is completed and before vibration is required, the user can manually close the cover plate 1161.
[0037] Reference Figure 9 The right end (bottom) of the first channel is provided with a first sealing plate 117 that can be opened and closed. The top end of the first sealing plate 117 is rotatably connected to the side plate 111 (e.g., via a pivot), and the bottom end is detachably connected to the first bottom plate 312 and / or the side plate 111 (e.g., via a spring buckle). The user can manually open the first sealing plate 117 to control the timing of the stones being discharged from the first channel (to avoid mixing with the stones discharged from the third channel).
[0038] Reference Figure 9 The second channel has a second sealing plate 118 that can be opened and closed at the left end (i.e., the bottom). The top end of the second sealing plate 118 is rotatably connected to the side plate 111 (e.g., via a pivot), and the bottom end is detachably connected to the second bottom plate 322 and / or the side plate 111 (e.g., via a spring buckle). The user can manually open the second sealing plate 118 to control the timing of the stones being discharged from the second channel.
[0039] Reference Figure 9 A third channel is provided between the screen assembly 114 and the top plate 116. A third sealing plate 119, which can be opened and closed, is located at the right end (i.e., the bottom) of the third channel. The top end of the third sealing plate 119 is rotatably connected to the side plate 111 (e.g., via a pivot), and the bottom end is detachably connected to the third mounting frame 1143 and / or the side plate 111 (e.g., via a spring-loaded buckle). Users can manually open the third sealing plate 119 to control the timing of stone discharge from the third channel (preventing mixing with stones discharged from the first channel).
[0040] Reference Figure 9 and Figure 3The upper part of the receiving cavity 110 is provided with an abutment crossbar 1110, and the two ends of the abutment crossbar 1110 are fixedly connected to two side plates 111 respectively (e.g., by bolts or by welding). The abutment crossbar 1110 is used to apply a supporting force between the upper parts of the two side plates 111 to prevent deformation of the upper parts of the side plates 111 (the lower parts of the two side plates 111 are supported by the first bottom plate 312 and the second bottom plate 322). An abutment ring 11101 is sleeved and fixed at the end of the abutment crossbar 1110 (e.g., by welding or by bolts). The end face of the abutment ring 11101 is attached to and fixedly connected to the inner wall of the side plate 111 (e.g., by welding or by bolts). The abutment ring 11101 is used to increase the force transmission area between the abutment crossbar 1110 and the side plate 111 to avoid the problem of force concentration and deformation of the side plate 111.
[0041] Reference Figure 6 and Figure 10 The inner wall of the side plate 111 is fixedly installed with a first square tube 11102, a second square tube 11103, and a third square tube 11104 (e.g., fixedly connected by bolts or by welding). Two first square tubes 11102 are provided and connected to two side plates 111 respectively; two second square tubes 11103 are provided and connected to two side plates 111 respectively; two third square tubes 11104 are provided and connected to two side plates 111 respectively. The bottom ends of the second base plate 322 are respectively pressed onto the upper surfaces of the two first square tubes 11102, and the first square tubes 11102 are used to assist the second base plate 322 in bearing the weight of the stones. The bottom ends of the first base plate 312 are respectively pressed onto the upper surfaces of the two second square tubes 11103, and the second square tubes 11103 are used to assist the first base plate 312 in bearing the weight of the stones. The bottom ends of the mounting frame 1143 are respectively pressed onto two third-party tubes 11104, which are used to assist the mounting frame 1143 in bearing the weight of the stones.
[0042] Reference Figure 1 , Figure 2 and Figure 3 The chamber module 1 also includes an extension block 12, which is fixedly connected to the outer wall of the side plate 111 of the vibrating chamber 11 (e.g., by welding or by bolts). The support module 2 includes legs 21 and a connecting block 22 disposed at the top of the legs 21. A vertical support spring 24 is installed between the connecting block 22 and the extension block 12. The bottom ends of adjacent legs 21 are connected by a reinforcing crossbar 23; the end of the reinforcing crossbar 23 is fixedly connected vertically to the bottom end of the legs 21 (e.g., by bolts or by welding). The bottom ends of the legs 21 are fixedly connected to the floor of the processing workshop (e.g., by expansion bolts).
[0043] Reference Figures 1-4The extension block 12 has a first insertion hole 121 on its bottom surface, and the connecting block 22 has a second insertion hole 221 on its top surface that fits the first insertion hole 121. The top and bottom ends of the vertical support spring 24 are respectively inserted into the first insertion hole 121 and the second insertion hole 221. A vibration gap is provided between the extension block 12 and the connecting block 22. When the vibration chamber 11 vibrates, it will undergo a slight vertical displacement. The vibration gap is used to provide space to accommodate the vertical displacement of the vibration chamber 11 and avoid the problem of collision between the extension block 12 and the connecting block 22.
[0044] Reference Figure 2 The extension block 12 has a strip-shaped structure and is arranged horizontally, so that a single extension block 12 can be connected to multiple vertical support springs 24.
[0045] Reference Figure 1 and Figure 4 A movable gap 220 is provided between the vibration chamber 11 and the connecting block 22. When the vibration chamber 11 vibrates, it will undergo a slight lateral displacement. The movable gap 220 is used to provide space for the lateral displacement of the vibration chamber 11 and avoid the problem of collision between the vibration chamber 11 and the connecting block 22. A cross brace spring 25 is installed in the movable gap 220.
[0046] Reference Figure 4 A limiting block 26 is provided in the movable gap 220. The limiting block 26 is fixedly connected to the outer wall of the side plate 111 (for example, by bolt or by welding). A fourth insertion hole 261 is provided on the side wall of the limiting block 26 away from the side plate 111. The connecting block 22 is provided with a third insertion hole 222 that is adapted to the fourth insertion hole 261. The two ends of the cross brace spring 25 are respectively inserted into the third insertion hole 222 and the fourth insertion hole 261.
[0047] Reference Figure 4 A sealing plate 223 is detachably installed at the end of the third insertion hole 222 away from the cross brace spring 25. The sealing plate 223 is detachably connected to the connecting block 22 (e.g., using bolts for detachable connection). Figure 4 Taking the perspective shown as an example, when assembling this utility model, the user can pass the cross brace spring 25 from left to right through the third insertion hole 222 and lock it in the fourth insertion hole 261. Then, the sealing plate 223 is connected to the connecting block 22, thereby preventing the cross brace spring 25 from popping out from the left end opening of the third insertion hole 222.
[0048] The width of the limiting block 26 is smaller than the width of the movable gap 220, thereby preventing the limiting block 26 from colliding with the connecting block 22.
[0049] Reference Figure 4 The vertical support spring 24 and the horizontal support spring 25 serve as an elastic connection between the connecting block 22 and the extension block 12, and are used to support the vibrating chamber 11 in a vibrating state. The vertical support spring 24 is a compression spring.
[0050] Reference Figure 3 and Figure 4 The side plate 111 has an extension 1111, a side recess 1112, and an inclined transition portion 1113. The top and bottom ends of the inclined transition portion 1113 are fixedly connected to the extension 1111 and the side recess 1112, respectively (e.g., by an integral fixed connection). The extension block 12 is fixedly connected to the outer wall of the extension 1111 (e.g., by welding or by bolts); the limiting block 26 is fixedly connected to the outer wall of the side recess 1112 (e.g., by welding or by bolts), thereby forming an active gap 220.
[0051] Reference Figure 1 , Figure 2 and Figure 5The drive module 3 includes a first support column 31, a second support column 32, and a crankshaft-type vibrator 33. The first support column 31 and the second support column 32 are respectively located on both sides of the vibration chamber 11. The crankshaft-type vibrator 33 is installed at both ends of the first support column 31 and the second support column 32. The crankshaft-type vibrator 33 includes a first motor 331, a crankshaft 332, a sleeve 333, a first coupling 334, a second coupling 335, a cross shaft 336, and a bearing 337. The housing of the first motor 331 is fixedly connected to the top of the first support column 31 (e.g., by bolts). The two ends of the first coupling 334 are respectively connected to the left end of the output shaft of the first motor 331 and the left end of the crankshaft 332. The two ends of the second coupling 335 are respectively connected to the right end of the crankshaft 332 and the left end of the cross shaft 336. The right end of the cross shaft 336 can... The crankshaft 332 is rotatably mounted in the bearing seat 337 (e.g., connected via a first bearing, the inner ring of which is fitted onto the outer surface of the cross brace 336 and bolted to it; the outer ring of which is placed inside the bearing seat 337 and bolted to it; balls or rollers are provided between the inner and outer rings; the first bearing is a dustproof bearing, a common technology in the industry, and will not be elaborated further). The bottom surface of the bearing seat 337 is pressed against and fixed to the top of the second support column 32 (e.g., bolted). A sleeve 333 is fitted onto the middle of the crankshaft 332, and the middle of the crankshaft 332 is rotatably connected to the sleeve 333; several second bearings are installed between the inner wall of the sleeve 333 and the outer wall of the middle of the crankshaft 332. Annular end caps are bolted to both ends of the sleeve 333, and the crankshaft 332 is inserted into the middle of the annular end caps, thereby improving the dustproof capability of the second bearings. The sleeve 333 is inserted into the two side plates 111 of the vibration chamber 11 at both ends. A first reinforcing ring 3331 is fixedly fitted onto the outer wall end of the sleeve 333 (e.g., by bolt or integral connection). The end face of the first reinforcing ring 3331 is attached to and fixedly connected to the side plate 111 (e.g., by bolt or welding). The first reinforcing ring 3331 is used to distribute the pressure between the sleeve 333 and the side plate 111, avoiding the problem of stress concentration and deformation of the side plate 111. When the output shaft of the first motor 331 rotates, it can drive the crankshaft 332 to rotate, thereby driving the sleeve 333 and the vibration chamber 11 (centered on the axis of the output shaft of the first motor 331) to rotate, thus realizing vibration.
[0052] Reference Figure 1 , Figure 2 and Figure 5The bottom end of the first upright column 31 is vertically fixed to the first base plate 312 (e.g., by welding or by bolts). The first base plate 312 is fixedly connected to the floor of the processing workshop (e.g., by expansion bolts). The top end of the first diagonal column 311 is fixedly connected to the middle of the first upright column 31 (e.g., by welding) and the bottom end is fixedly connected to the outer edge of the first base plate 312 (e.g., by welding). This strengthens the connection between the first base plate 312 and the first upright column 31 and prevents the first upright column 31 from tipping over. The bottom end of the second support column 32 is vertically fixed to the second base plate 322 (e.g., by welding or by bolts). The second base plate 322 is fixedly connected to the workshop floor (e.g., by expansion bolts). The top end of the second diagonal support column 321 is fixedly connected to the middle of the second support column 32 (e.g., by welding) and the bottom end is fixedly connected to the outer edge of the second base plate 322 (e.g., by welding). This strengthens the connection between the second base plate 322 and the second support column 32, preventing the second support column 32 from tipping over.
[0053] The motor is a controllable motor (e.g., a servo motor or a stepper motor); the first motor 331 is electrically connected to an external controller (e.g., a computer or a PLC programmable logic controller) via wires and signal lines; the user can input electrical signals to the controllable motor through the external controller to control the speed and start / stop timing of the controllable motor.
[0054] Screening steps: ① Close the first sealing plate 117 and the second sealing plate 118, and open the third sealing plate 119; then park the third transfer car 6 below the right end of the vibrating chamber 11 (refer to...). Figure 11 ); ② Open the cover plate 1161 and put stones (i.e., tunnel slag) into the inner cavity of the vibrating chamber 11 through the feeding port; then close the cover plate 1161; ③ Start the first motor 331 to make the vibrating chamber 11 vibrate, thereby realizing the screening of stones (some stones pass through the first screen 1141 and finally accumulate at the bottom of the second channel, some stones pass through the second screen 1142 and finally accumulate at the bottom of the first channel, and the remaining stones are discharged from the bottom of the third channel and fall into the hopper of the third transfer vehicle 6); ④ After all the stones in the third channel are discharged (the user can touch them), (Observed by eye) Stop the first motor 331 and the third transfer vehicle 6 drives away; ⑤ Open the first sealing plate 117 and the second sealing plate 118; then park the first transfer vehicle 4 and the second transfer vehicle 5 below the left and right ends of the vibration chamber 11 respectively; ⑥ Start the first motor 331 to make the vibration chamber 11 vibrate, and the stones discharged through the second channel fall into the truck bed of the first transfer vehicle 4, and the stones discharged through the first channel fall into the truck bed of the second transfer vehicle 5; ⑦ After all the stones in the first and second channels are discharged, the first transfer vehicle 4 and the second transfer vehicle 5 drive away.
[0055] The stones are classified by volume: stones discharged through the third channel and falling into the third transfer vehicle 6 are large stones; stones discharged through the first channel and falling into the second transfer vehicle 5 are medium stones; and stones discharged through the second channel and falling into the first transfer vehicle 4 are small stones.
[0056] Subsequent crushing methods (refer to) Figure 12 The third transfer vehicle 6 feeds large-volume stones into the primary crusher, the second transfer vehicle 5 feeds medium-volume stones into the secondary crusher, and the first transfer vehicle 4 feeds small-volume stones into the tertiary crusher. The primary crusher crushes the large-volume stones and outputs medium-volume stones, the secondary crusher crushes the medium-volume stones and outputs small-volume stones, and the tertiary crusher crushes the small-volume stones and outputs gravel / stone powder. A conveyor belt connects the primary and secondary crushers to transport medium-volume stones; that is, medium-volume stones from the primary crusher are fed into the secondary crusher. Similarly, a conveyor belt connects the secondary and tertiary crushers to transport small-volume stones; that is, small-volume stones from the secondary crusher are fed into the tertiary crusher.
[0057] To prevent noise from being generated by the bottom of the first sealing plate 117, the bottom of the second sealing plate 118, and the bottom of the third sealing plate 119 striking the side plate 111, a sponge layer can be fixedly installed (e.g., by adhesive bonding) at the bottom of the first sealing plate 117, the bottom of the second sealing plate 118, and the bottom of the third sealing plate 119, thereby reducing noise pollution.
[0058] This utility model has a simple structure and reliable function. The bottom opening of the first channel is located at the right end of the vibrating chamber 11, and the bottom opening of the second channel is located at the left end of the vibrating chamber 11. Therefore, the first transfer vehicle 4 and the second transfer vehicle 5 can be parked at the left and right ends of the vibrating chamber 11 respectively, thus solving the problem that the first transfer vehicle 4 and the second transfer vehicle 5 cannot be parked at the same end of the vibrating chamber 11 for receiving materials separately.
