Description

Technical Field

[0001] The invention relates to the technical field of lifting type coal plows, in particular to a balanced lifting type environmentally friendly coal plow. Background Art

[0002] The lifting coal plow, also known as the inclined plow unloader or the round plow unloader, is a kind of unloading equipment widely used in coal, electric power, metallurgy, building materials and other industries. Its main function is to complete the unloading of the material body on the conveyor belt.

[0003] The utility model patent with publication number CN219990447U discloses a coal plow, which makes the coal plow contact with the coal conveyor belt through the setting of rubber baffles, so that the coal with smaller particles is also transported to both sides under the action of the rubber baffles, preventing the small particles of coal from moving from the gap between the coal plow and the belt to the rear of the coal plow, thereby ensuring the utilization rate of the coal.

[0004] Although the above scheme can prevent small particles of coal from moving from the gap to the rear of the coal plow by directly contacting the coal plow with the conveyor belt, it will cause the coal to accumulate in the corner of the coal plow and stay at the edge of the conveyor belt. As the coal plow is subsequently lifted, the coal will fall from the edge of the conveyor belt, thereby reducing the utilization rate of the coal; in addition, since the coal is temporarily stored in the box during the unloading process, and the coal itself is unevenly distributed on the conveyor belt during the transportation process, the amount of coal carried in the box is uneven, and then when one box is full of coal and the coal in the other box is not yet full, the coal in the box is prone to overflow and fall, further reducing the utilization rate of the coal.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0035] See also Figure 1-Figure 2 A balanced lifting environmentally friendly coal plow comprises a bottom plate 1, a center block 11 is fixed on the top of the bottom plate 1, a bottom support mechanism 2 is arranged on the top of the center block 11, the bottom support mechanism 2 is located below the conveyor belt for conveying coal, two groups of limit bars 111 are fixed on the top of the bottom plate 1 and are symmetrical about the center block 11, a loading mechanism 3 is slidably connected to each group of limit bars 111, and a coal plow mechanism 4 is arranged on the top of the bottom plate 1 and at the rear side of the bottom support mechanism 2.

[0036] The present invention unloads coal through the bottom support mechanism 2 cooperating with the coal plow mechanism 4, and uses the loading mechanism 3 to store the coal unloaded by the coal plow mechanism 4, and the bottom support mechanism 2 can cooperate with the coal plow mechanism 4 to straighten the conveyor belt for transporting coal, so that the coal plow mechanism 4 can fully unload the coal on the conveyor belt into the loading mechanism 3, thereby avoiding the situation where a small amount of coal passes through the coal plow mechanism 4 from the middle position of the conveyor belt.

[0037] Specifically, the conveyor belt for transporting coal is located between the bottom support mechanism 2 and the coal plowing mechanism 4 when working. First, the coal plowing mechanism 4 is controlled to press the conveyor belt and press it against the bottom support mechanism 2. Then, the coal plowing mechanism 4 unloads the coal on the conveyor belt, so that the coal falls into the loading mechanism 3. After the unloading is completed, the coal plowing mechanism 4 is controlled to stay away from the conveyor belt, and the unloaded coal is taken out and collected from the loading mechanism 3.

[0038] See also Figure 1 , Figure 3 and Figure 5 The loading mechanism 3 includes a sliding plate 31 connected to the limit bar 111, and a power component 32 for controlling the reverse movement of the two sliding plates 31 is commonly connected to the two sliding plates 31, a plurality of compression springs are evenly arranged on the top of the sliding plate 31, and a loading box 311 is commonly connected to the top of the plurality of compression springs, and a discharge port 312 is arranged on the side of the loading box 311 away from the bottom support mechanism 2; the power component 32 includes a bidirectional threaded rod 321 rotatably mounted on the mid-position block 11, and the two threaded sections of the bidirectional threaded rod 321 are respectively threadedly connected to the two sliding plates 31, and the right end of the bidirectional threaded rod 321 is connected to the output end of a motor 322 mounted on the top of the bottom plate 1 through a motor box.

[0039] The loading mechanism 3 is used to collect the coal unloaded by the coal plowing mechanism 4, and performs the main collection work through the loading box 311. The power component 32 can be used to adjust the distance between the loading boxes 311 to adapt to conveyor belts of different sizes and allow the coal to fall from the edge of the conveyor belt into the loading box 311.

[0040] Specifically, first control the motor 322 to drive the bidirectional threaded rod 321 to rotate, and then synchronously adjust the position of the sliding plate 31 according to the size of the conveyor belt, so that the loading box 311 after adjustment can be close to the left and right edge positions of the conveyor belt, and then the coal unloaded by the coal plow mechanism 4 can all fall into the loading box 311.

[0041] See also Figure 3-Figure 5The bottom support mechanism 2 includes a vertical column 21 fixed to the top of the middle block 11, a collection plate 211 is fixed to the top of the vertical column 21, a plurality of fixed rods 212 are evenly fixed to the top of the collection plate 211, and a plurality of staggered fixed limiting components 22 and movable limiting components 23 are arranged above the collection plate 211, and the fixed limiting components 22 and the movable limiting components 23 are connected to the top of the corresponding fixed rods 212; the fixed limiting component 22 includes a mounting frame 221 fixed to the top of the corresponding fixed rod 212, A fixed roller 222 is rotatably installed in the mounting frame 221; the movable limiting component 23 includes a center rod 231 fixed to the top of the corresponding fixed rod 212, and movable rollers 232 are symmetrically sleeved on the left and right ends of the center rod 231. A limiting sleeve 233 is fixed to the side of the loading box 311 close to the bottom support mechanism 2 and corresponding to the position of each movable roller 232. A movable plate 234 is vertically slidably connected in the limiting sleeve 233, and the end of the movable roller 232 away from the fixed rod 212 is rotatably installed on the movable plate 234.

[0042] The bottom support mechanism 2 is used to provide bottom support for the conveyor belt. The staggered fixed limiting components 22 and movable limiting components 23 can prevent the conveyor belt from being uneven at the position of the coal plow mechanism 4, which may cause incomplete unloading of the coal plow mechanism 4. The movable limiting component 23 can synchronously adapt to the size of the conveyor belt according to the position of the loading box 311, so that the bottom support mechanism 2 can provide bottom support for conveyor belts of different sizes. At the same time, the movable roller 232 and the fixed roller 222 rotate with the movement of the conveyor belt, so that the bottom support mechanism 2 can support the conveyor belt without friction damage.

[0043] Specifically, as the bidirectional threaded rod 321 adjusts the position of the loading box 311, the limiting sleeve 233 and the moving plate 234 will move with the loading box 311, and drive the moving roller 232 to move toward the edge of the conveyor belt, thereby supporting the edge of the conveyor belt. As the coal plow mechanism 4 moves downward and presses the conveyor belt downward, the conveyor belt will be unfolded under the joint action of the coal plow mechanism 4, the moving roller 232 and the fixed roller 222, so that the edge of the conveyor belt corresponds to the area inside the loading box 311, thereby facilitating the coal plow mechanism 4 to transport the coal on the conveyor belt to the loading box 311.

[0044] See also Figure 6-Figure 7The coal plowing mechanism 4 includes a support column 41 fixed on the top of the bottom plate 1 and symmetrically distributed on the left and right sides of the mid-position block 11. A limited sliding column 411 is fixed on the top of the support column 41. A sliding sleeve 412 is slidably connected to the limited sliding column 411. A horizontal rod 413 is connected between the two sliding sleeves 412. A plow 414 is slidably connected to the upper limit of the horizontal rod 413. The plow 414 consists of a herringbone part for plowing coal and a longitudinal block part slidably connected to the horizontal rod 413. A horizontal plate is fixed on the top of the plow 414. 415, a scraping member 42 is arranged on the top of the horizontal plate 415, and a synchronization member 43 is arranged between the left and right ends of the plow 414; the coal plow mechanism 4 also includes a balancing member 44 and a pushing member 45 which are arranged on the top of the bottom plate 1 and distributed in the front and rear; the pushing member 45 includes a No. 2 cylinder 451 fixed on the top of the bottom plate 1, and the pushing end of the No. 2 cylinder 451 is connected to a U-shaped rod 452 through a connecting column, and the two vertical sections of the U-shaped rod 452 are respectively connected to the sliding sleeves 412 on the corresponding sides by connecting rods 453.

[0045] The coal plow mechanism 4 is used to unload the coal on the conveyor belt into the loading box 311, and mainly realizes the diversion and unloading of coal through the plow 414. At the same time, the synchronization component 43 cooperates with the balancing component 44, so that the plow 414 can quickly move horizontally after the loading box 311 on one side is full, and the coal is all unloaded into the loading box 311 on the other side through the plow 414, so as to achieve the purpose of filling both loading boxes 311, and avoid the situation that coal overflows due to continuing to unload the loading box 311 after one loading box 311 is full, thereby preventing coal waste.

[0046] Specifically, when the bidirectional threaded rod 321 completes adjusting the position of the loading box 311, the No. 2 cylinder 451 is controlled to move downward, and the two sliding sleeves 412 are driven to move downward synchronously through the U-shaped rod 452 and the connecting rod 453, so that the plow 414 moves downward together. As the plow 414 moves downward, the plow 414 will press down the conveyor belt and press the conveyor belt to the top of the movable roller 232 and the fixed roller 222. At this time, as the conveyor belt continues to convey, the plow 414 will unload the coal on the conveyor belt into the loading box 311.

[0047] See also Figure 6-Figure 8The scraping member 42 includes a No. 1 cylinder 421 installed on the top of the horizontal plate 415, a T-plate 422 is fixed to the pushing end of the No. 1 cylinder 421, and arc-shaped mounting plates 423 are symmetrically fixed to the left and right ends of the transverse section of the T-plate 422, and the arc-shaped mounting plate 423 is connected to an arc-shaped shovel plate 424 through a plurality of elastic telescopic rods on the arc surface away from the No. 1 cylinder 421, and the arc-shaped shovel plate 424 is used to shovel the coal accumulated on the side of the plow 414; a push rod 425 is fixed to the side of the arc-shaped shovel plate 424 away from the T-plate 422; extension plates 426 are symmetrically fixed to the left and right ends of the top of the horizontal plate 415, and a guide plate 427 is fixed to the front end of the extension plate 426, and the guide plate 427 is used to cooperate with the push rod 425 to push the arc-shaped shovel plate 424 forward, and the two arc-shaped shovel plates 424 form an eight-shaped shape with the small diameter end facing forward.

[0048] The scraping member 42 mainly scrapes away the coal accumulated on the side of the plow 414 through the arc shovel plate 424, and at the same time, the arc shovel plate 424 shovels the scraped coal into the loading box 311 by utilizing the cooperation of the guide plate 427 and the push rod 425, thereby preventing the coal from accumulating on the side of the plow 414 and falling from the edge of the conveyor belt after the plow 414 is lifted, causing waste of coal. At the same time, the arc shovel plate 424 can scrape and level the coal accumulated on the top of the loading box 311, thereby avoiding the situation where the coal falls due to the accumulation of coal on one side inside the loading box 311.

[0049] Specifically, when the plow 414 unloads the coal on the conveyor belt into the loading box 311, the No. 1 cylinder 421 is controlled to drive the arc mounting plate 423 to move up and down, and the arc shovel plate 424 will shovel the coal accumulated at the sharp corner of the plow 414 away from the herringbone part during the downward movement, and during the downward movement of the arc shovel plate 424, after the guide plate 427 and the pushed rod 425 contact, the guide plate 427 will push the pushed rod 425 forward and make the arc shovel plate 424 move forward. At this time, the arc shovel plate 424 will push the shoveled coal into the loading box 311, and as the arc shovel plate 424 moves forward, the arc shovel plate 424 will scrape the coal accumulated on the top of the loading box 311 and close to the conveyor belt, thereby preventing the coal from accumulating in the loading box 311 at the position where the plow 414 is away from the sharp corner of the herringbone part when it is almost full, thereby ensuring that the coal is stably accumulated in the loading box 311 and improving its utilization rate.

[0050] See also Figure 7 and Fig. 9The synchronization component 43 includes a lower extension rod 431 symmetrically fixed at the left and right ends of the plow 414, a synchronization plate 432 is fixed to the bottom of the lower extension rod 431, and a thrust plate 433 is fixed to the middle position of the bottom of the synchronization plate 432; a longitudinal sleeve 454 is fixed to the top of the horizontal section of the U-shaped rod 452 and corresponds to the position of the thrust plate 433, and a sliding positioning column 455 for fixing the position of the thrust plate 433 is slidably connected to the longitudinal sleeve 454, and the sliding positioning column 455 is fixed in position by cooperating with the vertical pins through the matching holes set thereon.

[0051] The synchronous component 43 mainly moves the plow 414 to the left and right position through the push plate 433, so as to automatically adjust the position of the plow 414 in cooperation with the balancing component 44, so that the plow 414 can automatically adapt to the unloading position of the coal, and at the same time, the sliding positioning column 455 is used to quickly position the synchronous component 43 and the plow 414 to the center position.

[0052] See also Figure 1 , Figure 3 , Figure 6 , Fig. 9 , Fig.10 and Fig.11 The balancing member 44 includes a support plate 441 fixed to the top of the bottom plate 1 symmetrically, the two support plates 441 are both located below the synchronous plate 432, a double-track slide rail 442 is fixed between the two support plates 441, and vertical slide bars 443 for horizontal sliding are staggered front and back on the double-track slide rail 442, the bottom of the vertical slide bar 443 passes through the double-track slide rail 442, and a moving sleeve 444 is fixed to the top of the vertical slide bar 443, a horizontal spring is connected between the moving sleeve 444 and the corresponding support plate 441, and a ramp block 445 is slidably connected to the inside of the moving sleeve 444 through a reset spring, and the vertical slide bar 443 is located between the ramp blocks 445; the two moving sleeves 444 are connected to the corresponding support plate 441, and the moving sleeve 444 is connected to the corresponding support plate 441 through a reset spring. The vertical slide bar 443 is located between the ramp blocks 445; the two moving sleeves 444 are connected to the corresponding support plate 441 by a horizontal spring, and the moving sleeve 444 is ..., and the vertical slide bar 443 is located between the two moving sleeves 444. The sides away from the movable sleeve 444 are provided with clearance grooves, and a pressure rod 446 is fixed at the position of the clearance groove on the side of the slope block 445; a lower pressure rod 447 for pressing the pressure rod 446 is fixed on the two loading boxes 311; a secondary bending plate 456 is fixed on the front side of the connecting column, and the secondary bending plate 456 is divided into two upper and lower staggered and parallel longitudinal plates and a vertical plate located between the two longitudinal plates, and a pushing inclined block 457 for pushing the vertical slide rod 443 and staggered front and back is fixed on the top of the longitudinal plate located on the front side of the secondary bending plate 456, and the lower end of the vertical slide rod 443 cooperates with the corresponding inclined surface of the pushing inclined block 457.

[0053] The balancing member 44 is used to cooperate with the synchronization member 43 to adjust the position of the plow 414, mainly by moving the ramp block 445 downward and quickly disengaging from the limit of the push plate 433 under the cooperation of the pressure rod 446 and the lower pressure rod 447, and allowing the ramp block 445 on the other side to pull the push plate 433 under the action of the horizontal spring force, thereby automatically and quickly adjusting the position of the plow 414, so that the unloading direction of the coal can be quickly adjusted.

[0054] Specifically, when the plow 414 unloads the coal on the conveyor belt into the loading box 311, the coal on the conveyor belt is unevenly distributed, resulting in different coal loading amounts in the two loading boxes 311, so that the loading box 311 on one side is loaded with more coal. When the loading box 311 on this side is almost full, under the action of gravity, the loading box 311 will drive the pressing rod 447 to move downward, and the pressing rod 447 will press the pressure rod 446 downward, so that the pressure rod 446 and the slope block 445 move downward together, and at this time the other slope block 445 and the movable sleeve 444 will move downward together. The push plate 433 will be pushed to move under the action of the rebound force of the corresponding horizontal spring. At this time, the push plate 433 will pass over the compressed compression rod 446 and the ramp block 445. The push plate 433 drives the plow 414 to move synchronously through the lower extension rod 431 and the synchronous plate 432, so that the position of the plow 414 can be changed quickly, and the sharp corner of the herringbone part of the plow 414 can be moved from the original middle position of the conveyor belt to a position close to one of the edges of the conveyor belt, and the coal will continue to be unloaded into the loading box 311 along one of the curved surfaces of the herringbone part of the plow 414.

[0055] When the position of the plow 414 is changed, the lower extension rod 431 will press against the sliding sleeve 412. In this state, the movable sleeve 444 and the slope block 445 are still continuously pushed by the horizontal spring, so that the slope block 445 cooperates with the sliding sleeve 412 to press against the plow 414, so that the position of the plow 414 is stable. At this time, the unfilled loading box 311 will continue to be loaded with coal unloaded by the plow 414. After it is also loaded with coal, the No. 2 cylinder 451 is controlled to drive the U-shaped rod 452 and the connecting rod 453 to move the plow 414 upward. , and detach from the conveyor belt position, and then the operator pushes the lower extension rod 431 to make the plow 414 return to the middle position, and fixes its position by sliding the positioning column 455, and then controls the No. 2 cylinder 451 to push the plow 414 upward again, and at the same time pushes the vertical slide bar 443 by pushing the inclined block 457 to make the ramp block 445 return to the initial position and clamp the pushed plate 433. During this process, the ramp block 445 will move downward due to the pressure of the pushed plate 433 and pop out under the action of the return spring when it moves to the side of the pushed plate 433.

[0056] In this embodiment, if Figure 6 As shown, in order to prevent the push plate 433 from moving up and down with the plow 414 and affecting the cooperation between the push plate 433 and the slope block 445, a limit rod 416 is fixed between the two support columns 41, the limit rod 416 passes through the synchronous plate 432, and the lower extension rod 431 adopts a telescopic rod structure.

[0057] See also Figure 3 and Figure 5 A guide slope 313 is provided in the loading box 311 and at the position corresponding to the discharge port 312. A movable plate 314 is vertically slidably connected to the loading box 311 and at the position of the discharge port 312. A locking key 315 is fixed on the top of the movable plate 314. Two positioning holes 316 arranged up and down are provided on the loading box 311. A positioning pin is connected between the locking key 315 and the positioning holes 316 at the corresponding positions. The loading box 311 is used to load coal, and the guide slope 313 can be used to guide the coal in the loading box 311, so that the coal is evenly distributed and easier to be discharged from the discharge port 312.

[0058] The working steps of the present invention are as follows: In the first step, the conveyor belt for conveying coal is located between the bottom support mechanism 2 and the coal plowing mechanism 4 when working. First, the motor 322 is controlled to drive the bidirectional threaded rod 321 to rotate, and then the position of the sliding plate 31 is synchronously adjusted according to the size of the conveyor belt, so that the loading box 311 after adjustment can be close to the left and right edge positions of the conveyor belt. As the position of the loading box 311 is adjusted, the limit sleeve 233 and the movable plate 234 will move with the loading box 311, and drive the movable roller 232 to move toward the edge position of the conveyor belt, thereby supporting the edge of the conveyor belt.

[0059] In the second step, when the bidirectional threaded rod 321 has completed adjusting the position of the loading box 311, the control pushing component 45 drives the two sliding sleeves 412 to move downward synchronously, so that the plow 414 moves downward together. As the plow 414 moves downward, the plow 414 will press down the conveyor belt and press the conveyor belt to the top of the movable roller 232 and the fixed roller 222. At this time, as the conveyor belt continues to transport, the plow 414 will unload the coal on the conveyor belt into the loading box 311. At this time, the sliding positioning column 455 is first pulled backward and away from the pushed plate 433.

[0060] In the third step, when the plow 414 unloads the coal on the conveyor belt into the loading box 311, the No. 1 cylinder 421 is controlled to drive the arc-shaped mounting plate 423 to move up and down, and the scraping component 42 will shovel the coal accumulated on the side of the plow 414, and through the cooperation of the guide plate 427 and the push rod 425, the scraping component 42 will also push the shoveled coal into the loading box 311, and at the same time smooth the coal accumulated on the top of the loading box 311.

[0061] In the fourth step, when the plow 414 unloads the coal on the conveyor belt into the loading box 311, the coal on the conveyor belt is unevenly distributed, resulting in different coal loading amounts in the two loading boxes 311, so that the loading box 311 on one side is loaded with more coal. When the loading box 311 on this side is almost full, under the action of gravity, the loading box 311 will drive the pressure rod 447 to move downward, and the pressure rod 447 will press the pressure rod 446 downward, so that the position of the plow 414 can be quickly changed under the cooperation of the balance member 44 and the synchronization member 43.

[0062] The fifth step is that after the position change of the plow 414 is completed, the lower extension rod 431 will press against the sliding sleeve 412. In this state, the movable sleeve 444 and the ramp block 445 are still continuously pushed by the horizontal spring, and due to the joint pressing action of the ramp block 445 and the sliding sleeve 412, the position of the plow 414 is stable, and the unfilled loading box 311 will continue to be loaded with the coal unloaded by the plow 414. After it is also loaded with coal, the pushing member 45 is controlled to move the plow 414 upward and away from the conveyor belt position. Subsequently, the operator pushes the lower extension rod 431 to make the plow 414 return to the middle position, and fixes its position by sliding the positioning column 455. Then, the pushing member 45 is controlled again to push the plow 414 upward, and at the same time, the balancing member 44 and the synchronous member 43 are both returned to the initial position; then the movable plate 314 is lifted and locked, and at this time, the material can be discharged from the discharge port 312 of the loading box 311.
