Description

Technical Field

[0001] The present invention relates to the field of coal presses, and particularly to an efficient mechanical fully automatic coal press. Background Art

[0002] A coal press generally refers to a device that pressure-molds pulverized coal by applying pressure. Existing coal presses usually transport pulverized coal to the inside of a mold through a feeding device. After completion, hydraulic equipment is used to press down for shaping. After pressing down, manual participation is required to disassemble the formed coal blocks in the mold. Due to the slow speed of the hydraulic pressure and the subsequent manual participation, the entire coal pressing process takes a relatively long time, reducing the overall processing efficiency. To solve this problem, there is an urgent need to design an efficient mechanical fully automatic coal press. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides the following technical solutions:

[0004] An efficient mechanical fully automatic coal press includes: a frame body, a pressure-feeding assembly that moves up and down along the frame body, and a feeding assembly arranged below the pressure-feeding assembly.

[0005] Specifically, the feeding assembly includes a support plate, a second telescopic rod arranged on one side of the support plate, and a discharge hopper arranged on the other side of the support plate. A plurality of coal pressing cavities are formed on the surface of the support plate. The power end of the second telescopic rod is connected to a material frame. A discharge rod is arranged below the coal pressing cavity, and the discharge rod can move up and down along the inner wall of the coal pressing cavity. When the second telescopic rod extends and pushes the material frame to completely surround the coal pressing cavity, the pressure-feeding assembly presses down to press the pulverized coal into the coal pressing cavity for shaping.

[0006] As an improvement of the above technical solution, the pressure-feeding assembly includes a base. A plurality of pressure rods are arranged on the lower end surface of the base. The number of the pressure rods is the same as that of the coal pressing cavities, and each pressure rod is coaxially arranged with one of the coal pressing cavities. The radius of the pressure rod is equal to the inner diameter of the coal pressing cavity.

[0007] As an improvement of the above technical solution, the adjusting assembly includes a rotatable rotating rod that threadedly penetrates through the middle position of the base. When the rotating rod rotates, the base moves linearly along the inner wall of the frame body.

[0008] As an improvement of the above technical solution, a turbine is integrally formed on the outer side of the rotating rod, and a rotatable worm is engaged with one side of the turbine.

[0009] As an improvement of the above technical solution, the adjusting assembly further includes a motor, a synchronous pulley, a transmission rod, a gear set, a first transmission gear, and a second transmission gear. The motor is disposed on one side of the frame body, and the power end of the motor is rotationally connected to the synchronous pulley through a synchronous belt. A transmission rod passes through the axis of the synchronous pulley, and a gear set is connected to the shaft body of the transmission rod. The power output gear of the gear set is connected to a first transmission gear, and a second transmission gear is engaged with one side of the first transmission gear. One end of the worm is key-connected to the central position of the second transmission gear.

[0010] As an improvement of the above technical solution, a C-shaped frame is detachably fixed inside the frame body. Both ends of the worm pass through the two branches of the C-shaped frame, and the second transmission gear is located outside the C-shaped frame.

[0011] As an improvement of the above technical solution, a plurality of connecting blocks are disposed outside the base, and a limiting plate is detachably fixed to the outside of the connecting blocks. The frame body includes at least one vertically disposed positioning plate. The limiting plate has a notch, and the positioning plate is embedded inside the notch.

[0012] As an improvement of the above technical solution, a first telescopic rod is disposed below the coal pressing cavity, and the power end of the first telescopic rod is fixed to the end of the discharging rod away from the coal pressing cavity.

[0013] As an improvement of the above technical solution, the coal pressing cavity formed on the surface of the support plate is disposed on the side close to the discharging hopper, and the rectangular area formed by the boundary connection of the coal pressing cavity is less than one-half of the surface area of the support plate.

[0014] Advantages of the present invention:

[0015] By providing the discharging rod and the matching auxiliary structure, a discharging method of pushing from the bottom upwards after pressing is provided. After discharging is completed, all the materials placed on the support plate are discharged by pushing the material frame, thus completing the process of pressing, pushing, and discharging in one. This process does not require manual participation and has a higher overall efficiency.

[0016] In addition, a transmission structure mainly composed of a turbine and a worm is further provided. Different from the existing hydraulic and pneumatic structures, the rotation of the motor is converted into the lifting of the entire base through the transmission of structures such as a gear set and a synchronous pulley. Its structural strength depends on the power output strength of the motor, and its controllability, processing speed, and finally generated pressure strength are all superior to traditional hydraulic and pneumatic structures.

Detailed implementation manners

[0024] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0025] In the prior art, a method of using hydraulic equipment for downward pressing and shaping is usually adopted to process coal blocks. After downward pressing, manual participation is required to disassemble the formed coal blocks in the press mold. Due to the slow speed of the hydraulic pressure and the subsequent manual participation, the entire coal pressing process takes a relatively long time, reducing the overall processing efficiency. To solve this problem, please refer to Figures 1 to 6 , to provide an efficient mechanical fully automatic coal press, including: a frame body 10, a coal pressing component 30 that moves up and down along the frame body 10, and a feeding component 20 arranged below the coal pressing component 30.

[0026] Specifically, the feeding component 20 includes a support plate 21, a second telescopic rod 25 disposed on one side of the support plate 21, and a discharge hopper 27 disposed on the other side of the support plate 21. A plurality of coal pressing cavities 22 are formed on the surface of the support plate 21. The power end of the second telescopic rod 25 is connected to a material frame 26. A discharge rod 23 is disposed below the coal pressing cavity 22. The discharge rod 23 can move up and down along the inner wall of the coal pressing cavity 22. When the second telescopic rod 25 extends and pushes the material frame 26 to completely surround the coal pressing cavity 22, the pressing component 30 presses down to press the pulverized coal into the coal pressing cavity 22 for molding.

[0027] First, pour the pulverized coal into the inner side of the material frame 26, and then push the entire material frame 26 forward through the second telescopic rod 25 until the entire material frame 26 surrounds the coal pressing cavity 22. This is to ensure that the coal in the material frame 26 can be fully pressed and to avoid the problem of the pulverized coal falling from the edge. When the pressing component 30 presses down, the pulverized coal is extruded into the interior of the coal pressing cavity 22 for shaping. After the shaping is completed, the pressing component 30 moves up, and after the material frame 26 returns to its original position, the discharge rod 23 at the bottom starts to move up along the coal pressing cavity 22. During the upward movement, the coal block is pushed out from the interior of the coal pressing cavity 22. At this time, move the material frame 26 forward again. While the pressed coal block is sent out from the discharge hopper 27 through the material frame 26, the next coal pressing operation is performed.

[0028] Through the above solution, manual participation in the operation of the pressed coal block can be avoided. The entire process only needs to be automatically processed to realize the four steps of feeding, pressing, pushing, and discharging. Among them, feeding can be assisted by equipment such as a screw feeder.

[0029] To further improve the design of the pressing component 30, please refer to Figures 1 to 4 , the pressing component 30 includes a base 31. A plurality of pressing rods 32 are disposed on the lower end surface of the base 31. The number of pressing rods 32 is the same as that of the coal pressing cavities 22, and each pressing rod 32 is coaxially disposed with one of the coal pressing cavities 22. The radius of the pressing rod 32 is equal to the inner diameter of the coal pressing cavity 22.

[0030] The pressing function of the coal mine is realized by the way of squeezing the pressing rod 32 into the interior of the coal pressing cavity 22. The shapes and sizes of the pressing rod 32 and the coal pressing cavity 22 can be adjusted according to the shape and size of the required coal block.

[0031] Among them, a first telescopic rod 24 is disposed below the coal pressing cavity 22. The power end of the first telescopic rod 24 is fixed to the end of the discharge rod 23 away from the coal pressing cavity 22.

[0032] That is, the discharge function from the bottom can be provided through the setting of the first telescopic rod 24. Since the pressure intensity required for discharging does not need to be too high, the first telescopic rod 24 at the bottom can adopt a cylinder to obtain a higher discharge response efficiency.

[0033] In the prior art, hydraulic equipment is usually used to compress and mold pulverized coal. However, the transmission efficiency of hydraulic equipment is relatively low, that is, the time required to compact the pulverized coal during the pressing process is relatively long. Although pneumatic equipment has a faster pressurization speed, due to the compressibility of gas, its overall output strength is lower than that of hydraulic equipment, resulting in the fact that the coal blocks cannot be fully compacted and it is easy to have the problem of incomplete molding. To solve this problem, please refer to Figures 2 to 6 , the adjusting assembly 40 includes a rotatable rotating rod 48, and the rotating rod 48 threadedly penetrates through the middle position of the base 31. When the rotating rod 48 rotates, the base 31 moves linearly along the inner wall of the frame body 10.

[0034] The function similar to that of a lead screw drive is realized by the rotation of the rotating rod 48. As long as the rotation of the rotating rod 48 is ensured, the lifting of the base 31 along the rotating rod 48 can be controlled. During this process, the position of the base 31 needs to be restricted. Specifically, please refer to Figures 2 to 6 , a plurality of connecting blocks 33 are arranged on the outer side of the base 31, and a limiting plate 34 is detachably fixed on the outer side of the connecting block 33. The frame body 10 includes at least one vertically arranged positioning plate 11. The limiting plate 34 has a notch, and the positioning plate 11 is embedded inside the notch.

[0035] That is, the cooperation between the edge of the positioning plate 11 and the limiting plate 34 forms a function similar to a limiting track, so that the entire base 31 can be restricted in the vertical movement.

[0036] To further improve the structural design of the adjusting assembly 40, please refer to Figures 2 to 5 , a turbine 481 is integrally formed on the outer side of the rotating rod 48, and a rotatable worm 47 is engaged on one side of the turbine 481.

[0037] The rotation of the worm 47 is used to drive the rotation of the turbine 481, and the rotation of the turbine 481 will naturally drive the rotation of the entire rotating rod 48. In this embodiment, the position of the rotating rod 48 is in a fixed state, and it can rotate along its own axis. Usually, the end of the rotating rod 48 is connected by a bearing, and the bearing is embedded inside the frame body 10. In this way, the rotating rod 48 can rotate and there will be no height change. In this case, when the position of the base 31 is restricted, the rotation of the rotating rod 48 will naturally drive the lifting of the base 31.

[0038] In the foregoing solution, it is only a simple transmission of a mechanical structure. In order to enhance the transmission effect and strengthen the pressing strength of rotation, please refer to Figures 2 to 6, specifically, the adjusting assembly 40 further includes a motor 41, a synchronous pulley 43, a transmission rod 44, a gear set 45, a first transmission gear 46, and a second transmission gear 471. The motor 41 is disposed on one side of the frame 10, and the power end of the motor 41 is rotationally connected to the synchronous pulley 43 through a synchronous belt 42. A transmission rod 44 is disposed through the axis of the synchronous pulley 43. A gear set 45 is connected to the shaft body of the transmission rod 44. The power output gear of the gear set 45 is connected to a first transmission gear 46. A second transmission gear 471 is engaged with one side of the first transmission gear 46. One end of the worm 47 is key-connected to the central position of the second transmission gear 471.

[0039] The motor 41 provides the main power output. The power is transmitted to the synchronous pulley 43 through the synchronous belt 42. Since the rotation speed of the motor 41 is relatively fast, in order to ensure the adjustment efficiency, the rotation speed is also reduced by the cooperation between the transmission rod 44 and the gear set 45. When the first transmission gear 46 rotates, its rotation speed is relatively slow, but the torque received is relatively large. In this case, not only the strength of the output force can be ensured, but also the controllability is greatly improved, which is more flexible and has higher controllability compared with hydraulic operation.

[0040] In one embodiment, please refer to Figures 2 to 5 , a C-shaped frame 12 is detachably fixed inside the frame 10. Both ends of the worm 47 penetrate through the two branches of the C-shaped frame 12, and the second transmission gear 471 is located outside the C-shaped frame 12.

[0041] The entire worm 47 is supported by the C-shaped frame 12, and the second transmission gear 471 thereon is also fixed. The multiple gears of the gear set 45 inside it are positioned by opening notches inside the frame 10. If there are some positions with relatively large resistance, the resistance can be reduced by installing bearings or applying lubricating oil.

[0042] In the foregoing solution, the position and size of the coal pressing cavity 22 are not restricted. In order to ensure the normal operation of the material frame 26, please refer to Figures 2 to 5 , the coal pressing cavity 22 opened on the surface of the support plate 21 is disposed on the side close to the discharge hopper 27. The rectangular area formed by the boundary connection line of the coal pressing cavity 22 is less than one-half of the surface area of the support plate 21.

[0043] As long as it is ensured that the space occupied by the coal pressing cavity 22 does not exceed one-half of the support plate 21, it can be ensured that when the material frame 26 moves to the edge position, all the coal blocks inside the coal pressing cavity 22 can be pushed out, thus completing the feeding and discharging operations in the entire process.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
