Description

Technical Field

[0001] This utility model relates to the field of transfer machine technology, specifically a self-moving lateral pushing transfer machine device. Background Technology

[0002] A transfer conveyor is a bridge-type scraper conveyor installed in the transport roadway of the exit section of the working face in a mine. It is mainly used to transfer coal transported by the scraper conveyor at the mining face from the roadway floor to a belt conveyor. In the coal mining process, it forms a supporting mechanism with the scraper conveyor, crusher, and belt conveyor to realize the function of continuous coal transportation.

[0003] The main working steps of the transfer machine in coal mining are as follows: 1. Material receiving stage: The mined coal is transported to the tail inlet of the transfer machine via a scraper conveyor. The coal falls into the tail trough of the transfer machine and is pulled into the conveying channel by the scraper chain; 2. Material lifting and transfer: The scraper chain pulls the coal upward along the bridge trough assembly, and the material is lifted to a high position in the roadway through the arched bridge body; 3. Unloading to the belt conveyor: After the coal reaches the head of the machine, it is accurately thrown into the receiving point of the belt conveyor below through the unloading trough. The head of the machine is connected to the belt conveyor guide rail by a traveling trolley to ensure dynamic alignment of the unloading position; 4. Pushing and adjustment stage: When the coal mining face advances, the entire transfer machine is moved by the hydraulic pushing system.

[0004] During the longwall mining process, the movement of the transfer machine and the mining of the working face can cause differences in elevation between the two roadways and unevenness in the working face floor. This can easily cause the front scraper conveyor to slide up or down, resulting in insufficient connection between the front scraper conveyor head and the transfer machine, causing the front scraper conveyor to pull back coal, and causing the chain and scraper to break.

[0005] Therefore, a self-propelled lateral conveying transfer machine is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 5 As shown, a self-propelled transverse conveyor device includes a housing 1; a clamping seat 2 is provided inside the housing 1; an overlapping hydraulic cylinder 3 is clamped and fixed inside the clamping seat 2; the piston rod of the overlapping hydraulic cylinder 3 passes through one end of the housing 1, and the piston rod of the overlapping hydraulic cylinder 3 can be inserted into the front chute of the front scraper conveyor; multiple trapezoidal blocks 4 are bolted to the top and bottom surfaces of the clamping seat 2; multiple right-angled trapezoidal push blocks 5 are slidably installed on the bottom and top surfaces of the housing 1; the inclined surface of the push block 5 slides in contact with the inclined surface of the trapezoidal block 4; and adjusting hydraulic cylinders 6 are provided on both sides of the interior of the housing 1, which can push the push blocks 5 to slide.

[0033] Specifically, the housing 1 includes a lower housing and an upper housing; the two sides of the lower housing and the upper housing are fixed and locked by multiple bolts; the bottom of the lower housing of the housing 1 is welded or bolted to the push-pull cylinder of the end bracket of the front scraper conveyor; the top surface of the upper housing of the housing 1 has through holes at both ends for passing the hydraulic oil pipes of the overlapping cylinder 3 and the adjusting cylinder 6 through the housing 1, and the hydraulic oil pipes of the overlapping cylinder 3 and the adjusting cylinder 6 are connected to the main valve of the end bracket of the transfer machine;

[0034] The clamping seat 2 includes a lower clamping seat and an upper clamping seat; the two sides of the lower clamping seat and the upper clamping seat are fixed and locked by multiple bolts; the top surface of the lower clamping seat and the bottom surface of the upper clamping seat are both provided with concave surfaces that match the overlapping oil cylinder 3.

[0035] The trapezoidal block 4 has an isosceles trapezoidal cross section, and the lower base of the trapezoidal block 4 is in contact with the outer wall of the clamping seat 2; the middle part of the trapezoidal block 4 is locked and fixed to the clamping seat 2 by multiple long screws.

[0036] The push block 5 has a right-angled trapezoidal structure; the bottom surface of the push block 5 contacts the inner top or bottom surface of the housing 1, and the inclined surface of the push block 5 slides in contact with the inclined surface of the trapezoidal block 4; a pair of ear plates are fixedly attached to the top of the side of the push block 5 away from the trapezoidal block 4.

[0037] The cylinder of the adjusting cylinder 6 is hinged to the inner side of the housing 1, and the piston rod end of the adjusting cylinder 6 is rotatably connected to a pair of ear plates on the side of the push block 5 away from the trapezoidal block 4.

[0038] The base of the transfer machine chute is provided with a connecting groove on the side near the overlapping cylinder 3 that matches the piston rod of the overlapping cylinder 3;

[0039] In practical use, when the front scraper conveyor moves upward, that is, when the front scraper conveyor moves towards the transfer machine, the space between the front scraper conveyor and the transfer machine is reduced. At this time, the piston rod of the overlapping cylinder 3 retracts, so that the piston rod of the overlapping cylinder 3 is still inserted in the connecting groove of the transfer machine chute base.

[0040] When the front scraper conveyor slides down, that is, when the front scraper conveyor moves away from the transfer machine, the space between the front scraper conveyor and the transfer machine increases. At this time, the extension of the overlapping cylinder 3 causes the piston rod of the overlapping cylinder 3 to be inserted into the connecting groove of the transfer machine chute base.

[0041] By extending and retracting the overlapping cylinder 3, the overlapping situation between the front scraper conveyor and the transfer machine is adjusted, thereby avoiding the phenomenon of the front scraper conveyor pulling back coal and causing the chain and scraper to break.

[0042] When there is a height difference between the front scraper conveyor and the transfer machine, the piston rod of the overlapping cylinder 3 is misaligned with the connecting groove of the transfer machine chute base. At this time, it is difficult for the front scraper conveyor and the transfer machine to overlap accurately.

[0043] When the height of the front scraper conveyor is higher than the height of the transfer machine, that is, when the height of the piston rod of the overlapping cylinder 3 is higher than the connecting groove of the transfer machine chute base; at this time, the adjusting cylinders 6 on both sides inside the box 1 and located at the top extend, pushing the push blocks 5 on both sides of the top of the box 1 closer together; at the same time, the adjusting cylinders 6 on both sides inside the box 1 and located at the bottom retract, causing the push blocks 5 on both sides of the top of the box 1 to move away from each other; the push blocks 5 on both sides of the top of the box 1 move closer together, squeezing the trapezoidal block 4 at the top, generating downward pressure on the clamping seat 2, while the push blocks 5 on both sides of the bottom of the box 1 move away from each other, causing the support positions of the bottom push blocks 5 and the bottom trapezoidal block 4 to move away from each other; thus, the height of the clamping seat 2 is reduced, which in turn reduces the height of the overlapping cylinder 3; at the same time, since the trapezoidal blocks 4 at the bottom and top of the support seat 2 are both supported by the push blocks 5 at the bottom and top, the stability of the clamping seat 2 and the overlapping cylinder 3 is effectively improved;

[0044] When the height of the front scraper conveyor is lower than the height of the transfer machine, that is, when the height of the piston rod of the overlapping cylinder 3 is lower than the connecting groove of the transfer machine chute base; at this time, the adjusting cylinders 6 on both sides inside the box 1 and located at the top retract, causing the push blocks 5 on both sides of the top of the box 1 to move away from each other; at the same time, the adjusting cylinders 6 on both sides inside the box 1 and located at the bottom extend, pushing the push blocks 5 on both sides of the top of the box 1 to move closer together; the push blocks 5 on both sides of the bottom of the box 1 move closer together, squeezing the trapezoidal block 4 at the bottom, generating an upward pushing force on the clamping seat 2; at the same time, the push blocks 5 on both sides of the top of the box 1 move away from each other, causing the support position of the push blocks 5 on the trapezoidal block 4 at the bottom to move away from each other; thereby increasing the height of the clamping seat 2, and consequently increasing the height of the overlapping cylinder 3.

[0045] By adjusting the movement of the push block 5 driven by the hydraulic cylinder 6, and in conjunction with the trapezoidal block 4, the height of the overlapping hydraulic cylinder 3 is controlled and adjusted, thereby facilitating the connection between the piston rod of the overlapping hydraulic cylinder 3 and the connecting groove of the transfer machine chute base; which in turn facilitates the accurate overlapping of the front scraper conveyor and the transfer machine.

[0046] In some embodiments, such as Figures 2 to 6 As shown, hinge seats 7 are bolted to both sides of the clamping seat 2; a V-shaped rotating arm 8 is rotatably mounted in the middle of the hinge seat 7; telescopic arms 9 are slidably mounted inside both ends of the rotating arm 8; the end of the telescopic arm 9 away from the hinge seat 7 is rotatably connected to the push block 5; both ends of the rotating arm 8 are hinged to the piston rod of the adjusting cylinder 6.

[0047] Specifically, the hinge seat 7 is fixed to the side of the clamping seat 2 by screws, and the hinge seat 7 corresponds to the push block 5; both ends of the rotating arm 8 are provided with sliding grooves, and the telescopic arm 9 is slidably installed in the sliding grooves of the rotating arm 8.

[0048] Two adjusting cylinders 6 are respectively hinged to both ends of the rotating arm 8. One adjusting cylinder 6 extends and the other adjusting cylinder 6 retracts, so that the rotating arm 8 rotates around the hinge seat 7. Since only the rotating arm 8 needs to be driven to rotate, one of the two adjusting cylinders 6 can be reduced, thereby effectively reducing the cost.

[0049] When adjusting the lifting height of the overlapping cylinder 3, the adjusting cylinder 6 pushes the rotating arm 8 to rotate around the hinge seat 7, causing the top of the rotating arm 8 to rotate away from the clamping seat 2, and the bottom of the rotating arm 8 to rotate towards the clamping seat 2. The telescopic arm 9 at the top of the rotating arm 8 slides out from the top groove of the rotating arm 8, driving the top push block 5 to move away from the clamping seat 2. At the same time, the telescopic arm 9 at the bottom of the rotating arm 8 slides into the bottom groove of the rotating arm 8, pushing the bottom push block 5 towards the clamping seat 2. The push blocks 5 on both sides of the bottom of the box 1 approach each other, squeezing the bottom trapezoidal block 4, generating an upward pushing force on the clamping seat 2. At the same time, the push blocks 5 on both sides of the top of the box 1 move away from each other, causing the support position of the bottom push block 5 on the bottom trapezoidal block 4 to move away from each other. This drives the overlapping cylinder 3 to rise.

[0050] When adjusting the lowering height of the overlapping cylinder 3, the adjusting cylinder 6 pushes the rotating arm 8 to rotate around the hinge seat 7, causing the bottom end of the rotating arm 8 to rotate away from the clamping seat 2, and the top end of the rotating arm 8 to rotate towards the clamping seat 2. The telescopic arm 9 at the bottom of the rotating arm 8 slides out from the bottom groove of the rotating arm 8, driving the bottom push block 5 to move away from the clamping seat 2. At the same time, the telescopic arm 9 at the top of the rotating arm 8 slides into the bottom groove of the rotating arm 8, pushing the top push block 5 towards the clamping seat 2. The push blocks 5 on both sides of the top of the box 1 approach each other, squeezing the top trapezoidal block 4, generating downward pressure on the clamping seat 2. At the same time, the push blocks 5 on both sides of the bottom of the box 1 move away from each other, causing the support positions of the bottom push blocks 5 and the bottom trapezoidal block 4 to move away from each other. This drives the overlapping cylinder 3 to lower the height.

[0051] The overlapping hydraulic cylinder 3 drives the rotating arm 8 and the telescopic arm 9 to rotate, while simultaneously driving the top push block 5 and the bottom push block 5 to move in opposite directions and at the same speed; thus ensuring the stability of the lifting and lowering of the overlapping hydraulic cylinder 3.

[0052] Furthermore, such as Figures 1 to 7 As shown, both sides of the inclined surface of the push block 5 are provided with arc-shaped chamfers; a circular through groove 10 is provided in the middle of one end of the piston rod of the overlapping oil cylinder 3 near the housing 1; the diameter of the circular through groove 10 is larger than the diameter of the piston rod of the overlapping oil cylinder 3.

[0053] Specifically, when there is an angle difference between the piston rod of the overlapping cylinder 3 and the connecting groove of the transfer machine chute base;

[0054] When the connecting groove of the transfer machine chute base is located below the piston rod of the overlapping cylinder 3, the piston rod of the overlapping cylinder 3 needs to be tilted downwards to insert into the connecting groove of the transfer machine chute base. At this time, on the side near the piston rod of the overlapping cylinder 3, the adjusting cylinder 6 drives the two top push blocks 5 to move closer together, while the two bottom push blocks 5 move further apart, causing the end of the overlapping cylinder 3 near the circular through groove 10 to move downwards. At the same time, on the side away from the piston rod of the overlapping cylinder 3, the adjusting cylinder 6 drives the two top push blocks 5 to move further apart, while the bottom push blocks 5 move further apart. The two push blocks 5 approach each other, causing the end of the overlapping cylinder 3 away from the circular through groove 10 to move upward; and the adjusting cylinder 6 located between the two ends of the overlapping cylinder 3 drives the corresponding push block 5 to move; so that the distance between the push blocks 5 on both sides of the bottom decreases sequentially from the piston rod end of the overlapping cylinder 3 to the cylinder barrel end of the overlapping cylinder 3, while the distance between the push blocks 5 on both sides of the top increases sequentially from the piston rod end of the overlapping cylinder 3 to the cylinder barrel end of the overlapping cylinder 3; thereby causing the piston rod of the overlapping cylinder 3 to tilt downward.

[0055] When the connecting groove of the transfer machine chute base is located above the inclined piston rod of the overlapping cylinder 3, the piston rod of the overlapping cylinder 3 needs to be tilted upwards to insert into the connecting groove of the transfer machine chute base. At this time, on the side near the piston rod of the overlapping cylinder 3, the adjusting cylinder 6 drives the two top push blocks 5 to move away from each other, while the two bottom push blocks 5 move closer together, causing the end of the overlapping cylinder 3 near the circular through groove 10 to move upwards. At the same time, on the side away from the piston rod of the overlapping cylinder 3, the adjusting cylinder 6 drives the two top push blocks 5 to move closer together, while the bottom push blocks 5 move closer together. The two push blocks 5 are moved away from each other, causing the end of the overlapping cylinder 3 away from the circular through groove 10 to move downward; and the adjusting cylinder 6 located between the two ends of the overlapping cylinder 3 drives the corresponding push block 5 to move, so that the distance between the push blocks 5 on both sides of the bottom increases sequentially from the piston rod end of the overlapping cylinder 3 to the cylinder barrel end of the overlapping cylinder 3, while the distance between the push blocks 5 on both sides of the top decreases sequentially from the piston rod end of the overlapping cylinder 3 to the cylinder barrel end of the overlapping cylinder 3; thereby causing the piston rod of the overlapping cylinder 3 to tilt upward.

[0056] By adjusting the hydraulic cylinder 6 to drive the push block 5 to move, and cooperating with the trapezoidal block 4, the height of each part of the overlapping hydraulic cylinder 3 is controlled and adjusted. Furthermore, due to the arc-shaped chamfer on both sides of the inclined surface of the push block 5, the trapezoidal block 4 can rotate at the inclined surface of the push block 5. In addition, the circular through groove with a diameter larger than the piston rod diameter of the adjusting hydraulic cylinder 6 is opened at the end of the housing 1, which allows the adjusting hydraulic cylinder 6 to rotate and adjust the inclination angle. This further facilitates the connection between the piston rod of the overlapping hydraulic cylinder 3 and the connecting groove of the transfer machine chute base, thereby facilitating the accurate overlapping of the front scraper conveyor and the transfer machine.

[0057] Furthermore, such as Figures 3 to 9As shown, multiple guide rails 11 are bolted to the top and bottom surfaces of the box 1; a guide groove 12 matching the guide rails 11 is opened in the middle of the bottom surface of the push block 5;

[0058] Specifically, multiple countersunk holes are evenly provided on the guide rail 11, and screws are used to pass through the countersunk holes on the guide rail 11 to fix it to the bottom and top surfaces of the box 1.

[0059] The push block 5 is slidably connected to the guide rail 11 through the bottom guide groove 12, so that the push block 5 slides along the guide rail 11, and the sliding lines of the push blocks 5 on both sides are kept consistent, thereby improving the accuracy and stability of the sliding of the push block 5.

[0060] Furthermore, such as Figures 7 to 10 As shown, storage slots 13 are provided on both sides of the guide groove 12; a limit strip 14 is provided inside the storage slot 13;

[0061] Specifically, the cross-section of the guide rail 11 is an I-shaped structure; the location of the storage slot 13 corresponds to the grooves on both sides of the guide rail 11.

[0062] Multiple stepped holes are provided on the bottom side of the push block 5, corresponding to the position of the storage groove 13; the inner wall of the stepped hole in the middle is threaded; a push screw 15 is installed in the thread of the stepped hole in the middle; a convex hole is provided on the limit strip 14 corresponding to the position of the stepped hole in the middle; a ring is threaded on the end of the push screw 15, and the ring is rotatably installed in the convex hole.

[0063] The inner walls of the stepped holes on both sides are smooth; guide screws 16 are slidably installed in the stepped holes on both sides; the limiting strip 14 has screw holes corresponding to the positions of the stepped holes on both sides, and the ends of the guide screws 16 are threadedly connected to the screw holes.

[0064] In practical use, when installing the push block 5, the limiting strip 14 is located in the storage groove 13. The push block 5 is placed on the guide rail 11, that is, the guide groove 12 is fitted on the outside of the guide rail 11, so that the storage groove 13 is aligned with the grooves on both sides of the guide rail 11. The operator uses a wrench to rotate the push screw 15. Due to the guidance of the guide screw 16, the limiting strip 14 slides from the storage groove 13 into the side groove of the guide rail 11, thereby installing the push block 5 onto the guide rail 11; which facilitates the operator's installation and disassembly work.

[0065] Furthermore, such as Figures 1 to 3 , Figures 11 to 12 As shown, a plurality of retractable and foldable rubber rings 17 are provided between the outer wall of the circular through groove 10 and the piston rod of the overlapping oil cylinder 3.

[0066] Specifically, the rubber ring 17 is circular in shape and has a corrugated cross-section, which allows the rubber ring 17 to stretch, fold and bend as it moves and adjusts with the overlapping cylinder 3.

[0067] A fixing cylinder 18 is fixedly connected to the inner ring of the rubber ring 17. The fixing cylinder 18 is sleeved on the outer ring of the piston rod of the overlapping cylinder 3. Multiple screw holes are opened around the outer rings of both ends of the fixing cylinder 18, and screws are installed in the internal threads of the screw holes to fix and lock the fixing cylinder 18 to the piston rod of the overlapping cylinder 3.

[0068] A fixing ring 19 is fixed to the outer ring of the rubber ring 17, and the cross section of the fixing ring 19 is U-shaped, so that the fixing ring 19 can be stuck in the circular through groove 10; after the lower shell and the upper shell of the box 1 are closed, the fixing ring 19 can be clamped and fixed.

[0069] The circular through groove 10 is sealed by multiple rubber rings 17. At the same time, the structure of the rubber rings 17 allows them to stretch, fold and bend as the overlapping cylinder 3 moves and adjusts. This not only does not affect the movement of the overlapping cylinder 3, but also prevents external dirt from entering the housing 1.

[0070] In some embodiments, such as Figures 1 to 3 As shown, a pin 20 is fixedly connected to the end of the piston rod of the overlapping cylinder 3;

[0071] Specifically, the piston rod end of the lap cylinder 3 has a threaded outer ring; one end of the pin 20 has a threaded hole, so that the pin 20 is threaded and fixed to the piston rod end of the lap cylinder 3 through the threaded hole; the other end of the pin 20 is tapered.

[0072] The pin 20 is matched with the connecting groove of the transfer machine chute base. By replacing the pin 20, it can be adapted to the connecting groove of the transfer machine chute base of different specifications, thus improving the applicability.

[0073] Working principle: When the front scraper conveyor moves upward, i.e., moves towards the transfer machine, the space between the front scraper conveyor and the transfer machine decreases. At this time, the piston rod of the overlapping cylinder 3 retracts, so that the piston rod of the overlapping cylinder 3 is still inserted in the connecting groove of the transfer machine chute base. When the front scraper conveyor moves downward, i.e. moves away from the transfer machine, the space between the front scraper conveyor and the transfer machine increases. At this time, the overlapping cylinder 3 extends, so that the piston rod of the overlapping cylinder 3 is inserted into the connecting groove of the transfer machine chute base.

[0074] By extending and retracting the overlapping cylinder 3, the overlapping situation between the front scraper conveyor and the transfer machine is adjusted, thereby avoiding the phenomenon of the front scraper conveyor pulling back coal and causing the chain and scraper to break.

[0075] When there is a height difference between the front scraper conveyor and the transfer machine, the piston rod of the overlapping cylinder 3 is misaligned with the connecting groove of the transfer machine chute base. At this time, it is difficult for the front scraper conveyor and the transfer machine to overlap accurately.

[0076] When the height of the front scraper conveyor is higher than the height of the transfer machine, that is, when the height of the piston rod of the overlapping cylinder 3 is higher than the connecting groove of the transfer machine chute base; at this time, the adjusting cylinders 6 on both sides inside the box 1 and located at the top extend, pushing the push blocks 5 on both sides of the top of the box 1 closer together; at the same time, the adjusting cylinders 6 on both sides inside the box 1 and located at the bottom retract, causing the push blocks 5 on both sides of the top of the box 1 to move away from each other; the push blocks 5 on both sides of the top of the box 1 move closer together, squeezing the trapezoidal block 4 at the top, generating downward pressure on the clamping seat 2, while the push blocks 5 on both sides of the bottom of the box 1 move away from each other, causing the support positions of the bottom push blocks 5 and the bottom trapezoidal block 4 to move away from each other; thus, the height of the clamping seat 2 is reduced, which in turn reduces the height of the overlapping cylinder 3; at the same time, since the trapezoidal blocks 4 at the bottom and top of the support seat 2 are both supported by the push blocks 5 at the bottom and top, the stability of the clamping seat 2 and the overlapping cylinder 3 is effectively improved;

[0077] When the height of the front scraper conveyor is lower than the height of the transfer machine, that is, when the height of the piston rod of the overlapping cylinder 3 is lower than the connecting groove of the transfer machine chute base; at this time, the adjusting cylinders 6 on both sides inside the box 1 and located at the top retract, causing the push blocks 5 on both sides of the top of the box 1 to move away from each other; at the same time, the adjusting cylinders 6 on both sides inside the box 1 and located at the bottom extend, pushing the push blocks 5 on both sides of the top of the box 1 to move closer together; the push blocks 5 on both sides of the bottom of the box 1 move closer together, squeezing the trapezoidal block 4 at the bottom, generating an upward pushing force on the clamping seat 2; at the same time, the push blocks 5 on both sides of the top of the box 1 move away from each other, causing the support position of the push blocks 5 on the trapezoidal block 4 at the bottom to move away from each other; thereby increasing the height of the clamping seat 2, and consequently increasing the height of the overlapping cylinder 3.

[0078] By adjusting the movement of the push block 5 driven by the hydraulic cylinder 6, and in conjunction with the trapezoidal block 4, the height of the overlapping hydraulic cylinder 3 is controlled and adjusted, thereby facilitating the connection between the piston rod of the overlapping hydraulic cylinder 3 and the connecting groove of the transfer machine chute base; which in turn facilitates the accurate overlapping of the front scraper conveyor and the transfer machine.

[0079] When there is an angle difference between the piston rod of the overlapping cylinder 3 and the connecting groove of the transfer machine chute base;

[0080] When the connecting groove of the transfer machine chute base is located below the piston rod of the overlapping cylinder 3, the piston rod of the overlapping cylinder 3 needs to be tilted downwards to insert into the connecting groove of the transfer machine chute base. At this time, on the side near the piston rod of the overlapping cylinder 3, the adjusting cylinder 6 drives the two top push blocks 5 to move closer together, while the two bottom push blocks 5 move further apart, causing the end of the overlapping cylinder 3 near the circular through groove 10 to move downwards. At the same time, on the side away from the piston rod of the overlapping cylinder 3, the adjusting cylinder 6 drives the two top push blocks 5 to move further apart, while the bottom push blocks 5 move further apart. The two push blocks 5 approach each other, causing the end of the overlapping cylinder 3 away from the circular through groove 10 to move upward; and the adjusting cylinder 6 located between the two ends of the overlapping cylinder 3 drives the corresponding push block 5 to move; so that the distance between the push blocks 5 on both sides of the bottom decreases sequentially from the piston rod end of the overlapping cylinder 3 to the cylinder barrel end of the overlapping cylinder 3, while the distance between the push blocks 5 on both sides of the top increases sequentially from the piston rod end of the overlapping cylinder 3 to the cylinder barrel end of the overlapping cylinder 3; thereby causing the piston rod of the overlapping cylinder 3 to tilt downward.

[0081] When the connecting groove of the transfer machine chute base is located above the inclined piston rod of the overlapping cylinder 3, the piston rod of the overlapping cylinder 3 needs to be tilted upwards to insert into the connecting groove of the transfer machine chute base. At this time, on the side near the piston rod of the overlapping cylinder 3, the adjusting cylinder 6 drives the two top push blocks 5 to move away from each other, while the two bottom push blocks 5 move closer together, causing the end of the overlapping cylinder 3 near the circular through groove 10 to move upwards. At the same time, on the side away from the piston rod of the overlapping cylinder 3, the adjusting cylinder 6 drives the two top push blocks 5 to move closer together, while the bottom push blocks 5 move closer together. The two push blocks 5 are moved away from each other, causing the end of the overlapping cylinder 3 away from the circular through groove 10 to move downward; and the adjusting cylinder 6 located between the two ends of the overlapping cylinder 3 drives the corresponding push block 5 to move, so that the distance between the push blocks 5 on both sides of the bottom increases sequentially from the piston rod end of the overlapping cylinder 3 to the cylinder barrel end of the overlapping cylinder 3, while the distance between the push blocks 5 on both sides of the top decreases sequentially from the piston rod end of the overlapping cylinder 3 to the cylinder barrel end of the overlapping cylinder 3; thereby causing the piston rod of the overlapping cylinder 3 to tilt upward.

[0082] By adjusting the hydraulic cylinder 6 to drive the push block 5 to move, and cooperating with the trapezoidal block 4, the height of each part of the overlapping hydraulic cylinder 3 is controlled and adjusted. Furthermore, due to the arc-shaped chamfer on both sides of the inclined surface of the push block 5, the trapezoidal block 4 can rotate at the inclined surface of the push block 5. In addition, the circular through groove with a diameter larger than the piston rod diameter of the adjusting hydraulic cylinder 6 is opened at the end of the housing 1, which allows the adjusting hydraulic cylinder 6 to rotate and adjust the inclination angle. This further facilitates the connection between the piston rod of the overlapping hydraulic cylinder 3 and the connecting groove of the transfer machine chute base, thereby facilitating the accurate overlapping of the front scraper conveyor and the transfer machine.
