Description

Technical Field

[0001] The invention relates to the technical field of conveying, in particular to a reciprocating transmission conveying device. Background Art

[0002] The technology of conveying and discharging a variety of solid particles is a very common material conveying technology in industrial production. It is widely used in construction, chemical, pharmaceutical, food, agriculture and other industries. This technology is mainly used to evenly mix solid particle materials of different types and properties before conveying or discharging. For example, in the chemical industry, plastic particles and chemical reagent powders, in the food industry, grain spices, pharmaceutical raw materials are conveyed, and in agricultural fertilizers, compound fertilizers and trace element fertilizers are mixed, and mineral raw materials are mixed. Material conveying technology is used.

[0003] In the mixed conveying and discharging of various solid particles, fixed particles are usually transported and stored in silos before specific use, in order to facilitate batch management, quality control, mixing preparation and logistics optimization. During transportation and storage, the various materials to be stored are first transported to the silo through the conveying pipe by an external pumping machine, but the conveying position of the conveying pipe currently used is usually fixed. When the material is transported to the silo through the conveying pipe, it will form an accumulation under the conveying pipe, and the accumulation will affect the smoothness and effect of the subsequent material transportation process. In addition, manually adjusting the position of the material in the silo at a fixed time will not only be time-consuming and labor-intensive, but also increase costs. At the same time, due to material accumulation, it will be difficult to evenly lay the material in the silo, which will reduce the utilization rate of the internal space of the silo.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a reciprocating transmission conveying device comprises: an L-shaped frame 1, the left end of the frame 1 is connected to an external manipulator (not shown in the figure), the frame 1 is provided with an adjusting unit 2 for fixing and supporting the frame 1 and adjusting its position, a connecting block 3 is slidably provided on the rear end surface of the transverse section of the frame 1, an L-shaped transverse plate 30 is fixedly provided on the lower end surface of the connecting block 3, a connecting frame 31 is slidably provided on the lower end surface of the horizontal section of the transverse plate 30 through two vertical rods distributed left and right and with vertical axes, a conveying pipe 32 is vertically penetrated and installed at the rear end of the connecting frame 31, and a discharge pipe 33 is fixedly provided on the lower end surface of the conveying pipe 32 through an elastic tube.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the conveying pipe 32 is provided with a conveying unit 4 for conveying a variety of materials, and the conveying unit 4 includes a feed barrel 40, and the upper end surface of the conveying pipe 32 is fixedly provided with a feed barrel 40 with an opening at the lower end, and the feed barrel 40 is composed of a cylindrical section and an inverted truncated cone section from top to bottom, and a conveying plate 41 located in the conveying pipe 32 is rotatably provided on the feed barrel 40 through a rotating shaft with a vertical axis, and the rotating shaft is connected to an external motor (not shown in the figure), and the conveying plate 41 is spiral-shaped, and a plurality of feed pipes 42 distributed along the circumference of the rotating shaft are installed through the upper end of the feed barrel 40, and the feed pipes 42 are connected to an external pumping machine (not shown in the figure), and a dividing plate 43 corresponding to the feed pipes 42 and located on the lower side of the feed pipes 42 is fixedly sleeved on the rotating shaft.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the frame 1 is provided with a driving mechanism 5, and the driving mechanism 5 includes a guide groove 50. The guide groove 50 is opened on the transverse section of the frame 1, and a guide column 500 slidably connected to the guide groove 50 is rotatably provided on the upper end surface of the transverse plate 30. A moving block 501 located on the right side of the guide column 500 is slidably provided in the guide groove 50, and the adjusting unit 2 is arranged between the longitudinal section of the frame 1 and the moving block 501. The moving block 501 and the frame 1 are jointly provided with a driving unit 51.

[0035] During operation, the external manipulator drives the frame 1 to move, and then adjusts the position of the conveying pipe 32 through the adjustment unit 2 according to the length and width of the silo, so that the conveying pipe 32 is located in the middle position of the front and rear directions of the silo, and limits the distance that the conveying pipe 32 moves in the left and right directions to adapt to the length of the silo. Then the driving unit 51 works to make the moving block 501 drive the conveying pipe 32 and the discharge pipe 33 to move back and forth left and right. During this movement, the external pumping machine works to pump the material into the feed pipe 42, and at the same time, the external motor drives the rotating shaft to rotate, and the rotating shaft drives the conveying plate 41 and the dividing plate 43 to rotate synchronously. The dividing plate 43 blocks each feed pipe 42 in turn during the whole rotation, controls the rate of material discharge from the feed pipe 42, and assists in mixing multiple materials. During the rotation of the conveying plate 41, it drives multiple materials to be output from top to bottom through the conveying pipe 32 and the discharge pipe 33. In summary, while the discharge pipe 33 moves back and forth left and right, the material is transported into the silo through the discharge pipe 33 and transported and accumulated from left to right, avoiding the problem of excessive material accumulation at a single location affecting the transportation process and causing material overflow.

[0036] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the adjustment unit 2 includes a transition frame 20, the transition frame 20 is fixedly provided on the lower end surface of the moving block 501, the fixed frame 21 is fixedly provided on the longitudinal section of the frame 1 and the transition frame 20, the opposite surfaces of the two fixed frames 21 are fixedly provided with T-shaped frames 22, the two T-shaped frames 22 are symmetrical on the left and right, and the transverse sections of the two T-shaped frames 22 are relatively arranged, and the opposite surfaces of the transverse sections of the two T-shaped frames 22 are provided with two front-to-back symmetrical sliding plates 23 for forward and backward sliding, and the opposite surfaces of the two sliding plates 23 opposite to each other on the left and right are fixedly provided with L-shaped fixed plates 24, and the positive corners of the fixed plates 24 face the corresponding corners in the silo.

[0037] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the adjustment unit 2 also includes a bidirectional threaded rod 25, and a bidirectional threaded rod 25 with an axis extending from front to back is rotatably arranged on the transverse section of the T-shaped frame 22. The bidirectional threaded rod 25 passes through two adjacent sliding plates 23 and is threadedly matched with the two sliding plates 23. The bidirectional threaded rod 25 is connected to an external motor 2 (not shown in the figure).

[0038] like Figure 1 and Figure 4 As shown, the front end surface of the transverse section of the frame 1 is provided with a through slot 26 connected to the guide slot 50, and the front end surface of the moving block 501 is fixedly provided with a bolt 27 penetrating the through slot 26, and a nut is threadedly fitted on the bolt 27.

[0039] like Figure 1-Figure 6 , when working as shown, the external manipulator works and drives the frame 1 to move to the top of the silo, and makes the fixed plate 24 located directly above the inner cavity of the silo, loosens the nut and moves the moving block 501, so that the right sliding plate 23 is located above the right end of the silo, and the left sliding plate 23 is located above the left end of the silo, and makes the fixed plate 24 close to the corresponding inner wall in the silo, and then tightens the bolt 27 to fix and lock the moving block 501. The distance of the reciprocating movement of the conveying pipe 32 to the left and right is adjusted and controlled in the above manner to ensure that the conveying process of the conveying pipe 32 is above the inner cavity of the silo.

[0040] After that, the external manipulator moves down to place the frame 1 until the sliding plate 23 contacts the upper end surface of the silo. In this way, the frame 1, the conveying unit 4 and the driving mechanism 5 are supported. After that, the external motor 2 works to drive the bidirectional threaded rod 25 to rotate synchronously, so that the two sliding plates 23 on the same bidirectional threaded rod 25 are moved away from each other, and thus the two fixed plates 24 on the same T-shaped frame 22 are moved away from each other and pressed against the inner wall of the silo, completing the adaptive adjustment of the width direction of the silo (i.e., the distance in the front and back directions). It should be noted that the transverse section of the T-shaped frame 22 and the conveying pipe 32 are located in the same vertical plane in the left and right directions. Therefore, after completing the above adjustment, the conveying pipe 32 is located in the middle position in the front and back directions of the silo, which is convenient for the material to fall to the middle position in the front and back directions of the silo and spread to the front and back sides when conveying the material, so as to maximize the use of the storage space of the silo. In summary, the above method ensures that the material can be accurately conveyed to the silo while improving the applicability of the device to silos of different sizes.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the driving unit 51 includes a mounting frame 510 fixedly arranged on the upper end surface of the horizontal section of the frame 1 and the upper end surface of the moving block 501, and a driving roller 511 is rotatably arranged on the two mounting frames 510 through a driving shaft with a vertical axis, and a conveying chain 512 is commonly arranged between the two driving rollers 511, and any one of the driving shafts is connected to an external motor 3 (not shown in the figure), and a transmission chain 512 is arranged between the conveying chain 512 and the guide column 500 for driving the transverse plate 30 and the connecting frame 31 to move back and forth left and right. The connecting piece includes a transmission block 513 fixedly arranged on the lower end face of the conveyor chain 512, the lower end face of the transmission block 513 is in sliding contact with the upper end face of the horizontal section of the frame 1, a connecting rod 514 is installed on the transmission block 513 and is slidably penetrated, the connecting rod 514 is fixedly connected to the guide column 500, a mounting circular plate is fixedly arranged on the end face of the connecting rod 514 away from the guide column 500, and a spring 515 sleeved on the connecting rod 514 is fixedly arranged between the mounting circular plate and the transmission block 513. It should be noted that the lower end face of the drive shaft is flush with the lower end face of the corresponding drive roller 511, there is a gap between the lower end face of the drive roller 511 and the upper end face of the horizontal section of the frame 1, the lower end face of the guide column 500 and the connecting rod 514 are both located below the lower end face of the drive roller 511, and the drive shaft will not cause obstruction to the connecting rod 514 when the transmission block 513 drives the connecting rod 514 to move with the conveyor chain 512.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the frame 1 is provided with an adjusting member for keeping the conveyor chain 512 taut, and the adjusting member includes a placing plate 516. An L-shaped placing plate 516 is fixedly provided on the front end face of the frame 1, and a mounting plate 517 is fixedly provided on the rear end face of the vertical section of the placing plate 516 through a spring telescopic rod extending from front to rear through an axis, and a tensioning roller 518 for tightening the conveyor chain 512 is fixedly provided on the mounting plate 517 through a vertical column.

[0043] During operation, when the moving block 501 is located at the rightmost end of the guide slot 50, i.e., the initial position, the spring telescopic rod 1 is in the maximum stretched state, and the conveyor chain 512 is in the tightened state. In the process of moving the moving block 501 to adjust the length of the silo, the moving block 501 is synchronously moved to the left through the mounting frame 510 and the driving roller 511 thereon. In this process, the spring telescopic rod 1 is still and always in the stretched state, and the elastic force generated by the deformation of the spring telescopic rod 1 causes the tightening roller 518 to pull the conveyor chain 512 forward, maintaining the conveyor chain 512 in a tight state.

[0044] When conveying materials, the external motor drives the drive shaft to rotate synchronously, and the drive shaft drives the conveyor chain 512 to run through the drive roller 511. During the movement, the conveyor chain 512 drives the transmission block 513, the connecting rod 514 and the guide column 500 to move synchronously. Through the cooperation between the guide column 500 and the guide groove 50, during the full rotation of the conveyor chain 512, the guide column 500 drives the transverse plate 30, the connecting frame 31 and the conveying pipe 32 to move back and forth stably, thereby carrying out material conveying operations.

[0045] Secondly, it should be noted that during the movement of the transmission block 513 throughout a circle, the elastic properties of the spring 1 515 itself adapt to the change in the distance between the guide column 500 and the transmission block 513 during the reciprocating movement of the guide column 500.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, the driving mechanism 5 also includes a swinging group 52 arranged between the frame 1 and the discharge pipe 33, and the swinging group 52 includes a connecting bar 520, and the discharge pipe 33 is fixedly provided with a connecting bar 520, and the upper end surface of the connecting bar 520 is hinged with a moving bar 521, and the moving bar 521 is slidably arranged on the connecting frame 31 back and forth, and a return spring 522 located at the front side of the moving bar 521 is fixedly arranged between the moving bar 521 and the connecting frame 31, and a wavy matching plate 523 is fixedly arranged on the upper end surface of the frame 1 through a connecting piece, and the matching plate 523 is located on the rear side of the conveyor chain belt 512 and above the connecting rod 514, and a lower pressure bar 524 located above the matching plate 523 is fixedly arranged on the upper end surface of the moving bar 521 through a spring telescopic rod with a vertical axis, and a matching bar 525 matching the rear side surface of the matching plate 523 is fixedly arranged on the lower end surface of the lower pressure bar 524.

[0047] It should be noted that, in the initial state, the spring telescopic rod 52 is in a stretched state, and the return spring 522 is in a stretched state. When working, in the process of the guide column 500 driving the transverse plate 30 to move back and forth left and right, the transverse plate 30 drives the moving bar 521 thereon to move back and forth left and right synchronously, and the moving bar 521 and the lower pressing bar 524 and the matching plate 523 thereon move synchronously, because the moving bar 521 has a tendency to move forward under the elastic force generated by the deformation of the return spring 522, and then the matching plate 523 is always pressed against the matching plate 5 23, so in the process of reciprocating movement of the matching plate 523, the matching plate 523 pushes the matching bar 525 through the process of the matching bar 525 contacting with the wavy arc surface on the rear side of the matching plate 523, so that the moving bar 521 moves back and forth, and the moving bar 521 makes the opening of the discharge pipe 33 swing back and forth in the same front and rear vertical planes through the connecting bar 520. In the process of conveying materials, the above operation ensures that the materials can be evenly conveyed to the silo, avoiding excessive accumulation of materials in a certain place to affect the material conveying and material storage process.

[0048] Secondly, during the subsequent up and down movement of the connecting frame 31, the elastic force generated by the deformation of the spring telescopic rod ensures that the lower pressure strip 524 is always in close contact with the upper end surface of the matching plate 523, that is, the matching strip 525 is always at the same horizontal height as the arc surface of the matching plate 523, ensuring that the two can still be in contact and match after the connecting frame 31 moves up and down.

[0049] like Figure 1 , Figure 4 , Figure 6 and Figure 7As shown, the frame 1 and the connecting frame 31 are jointly provided with a lifting group 53, and the lifting group 53 includes an E-shaped plate 530. The lower end surface of the horizontal section of the frame 1 and the left end surface of the transition frame 20 are both fixedly provided with the E-shaped plate 530 through a mounting member. A guide rail assembly located at the front side of the transverse plate 30 is jointly fixedly provided on the two E-shaped plates 530. The guide rail assembly includes three groups of plate groups arranged equidistantly from top to bottom, and the plate group includes two left-right symmetrical U-shaped guide rails 531, and the openings of the two left-right corresponding U-shaped guide rails 531 are arranged oppositely, and the lower end of the uppermost U-shaped guide rail 531 on the right and the lower end of the middle U-shaped guide rail 531 on the left are both provided with a slot-5 32, the inner wall of the slot 1 532 is fixedly connected to the upper end of the adjacent lower guide rail through an inclined plate 533, and the two inclined plates 533 are symmetrical. Taking the left inclined plate 533 as an example, the left inclined plate 533 is inclined upward from left to right, and the upper end of the left lower U-shaped guide rail 531 and the upper end of the right middle U-shaped guide rail 531 are both provided with a slot 2, and a guide rail column 534 with an axis extending from front to rear is fixedly provided on the front end surface of the connecting frame 31, and the guide rail column 534 slides up and down to pass through the vertical section of the transverse plate 30 and is located in the corresponding U-shaped guide rail 531, and a reinforcing bar 535 is fixedly provided between the front sides of the three U-shaped guide rails 531 on the same side.

[0050] like Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, the lifting group 53 also includes an auxiliary component 56. The auxiliary component 56 is provided on the U-shaped guide rail 531 at the lower left side and the U-shaped guide rail 531 in the middle of the right side. The two auxiliary components 56 are symmetrical about the left and right centers. The auxiliary component 56 on the left side is used as an example for explanation. The left end face of the U-shaped guide rail 531 at the lower left side is fixedly provided with an L-shaped mounting block 560. The horizontal section of the mounting block 560 slides up and down and is penetrated by a clamping rod 561. The upper end face of the clamping rod 561 is fixedly provided with a clamping piece 562 that penetrates the corresponding U-shaped guide rail 531. A spring 2 563 is fixedly provided between the clamping piece 562 and the mounting block 560. The clamping piece 562 is a vertical section and a right-angle trapezoidal section from top to bottom, and the inclined surface of the right-angle trapezoidal section faces the adjacent inclined plate 533.

[0051] like Figure 6 As shown, the right end surfaces of the upper and lower horizontal sections of the U-shaped guide rail 531 on the left are fixedly provided with connecting columns 57, and the connecting columns 57 slide through the corresponding horizontal section of the corresponding U-shaped guide rail 531 on the right.

[0052] like Figure 1-Figure 8As shown, in the initial state, the guide rail column 534 is located at the right position in the lowermost guide rail on the right. During operation, as the external motor three works to move the conveyor chain 512, the guide column 500 drives the connecting frame 31 and the guide rail column 534 to move left. When the guide rail column 534 moves to the left to the left position of the lower left U-shaped guide rail 531 on the left, and begins to contact the inclined surface of the right-angled trapezoidal section of the clamping member 562 in the auxiliary component 56 on the left. As the guide rail column 534 continues to move, the guide rail column 534 pushes the clamping member 562, causing the clamping member 562 to move downward and the spring 2 563 to be compressed. Finally, the upper end surface of the right-angled trapezoidal section of the clamping member 562 moves to the lower side of the U-shaped guide rail 531, and at this time, the guide rail column 534 stops moving to the left and starts Moving to the right, the elastic force generated by the deformation of spring 2 563 causes the upper end surface of the right-angled trapezoidal section of the clamping piece 562 to push the guide post 500 upward and reset the clamping piece 562, so that the guide post 500 moves out of the section of the U-shaped guide rail 531 and contacts the corresponding inclined plate 533. Then, as the guide post 500 begins to move to the right, the cooperation between the guide post 500 and the left inclined plate 533 causes the guide rail post 534 to move to the right and move up to the middle U-shaped guide rail 531 on the left. Then, the guide rail post 534 moves right from the middle U-shaped guide rail 531 on the left to the right side of the middle U-shaped guide rail 531 on the right. Then, referring to the principle of the above-mentioned working process, the guide rail post 534 moves up to the U-shaped guide rail 531 on the upper right side and begins to move to the left.

[0053] In the above process, the lifting group 53 enables the connecting frame 31 and the conveying pipe 32 to move up a specified distance in sequence during the left and right reciprocating movement, thereby freeing up the required space for the material conveying and stacking process, ensuring that the material can be evenly conveyed and evenly stacked in the silo.

[0054] Secondly, it should be noted that during the adjustment of the moving block 501, the U-shaped guide rail 531 on the right side moves right synchronously along the connecting column 57. The setting of the connecting column 57 ensures that the guide column 534 can stably move left and right horizontally between the U-shaped guide rails 531 on the left and right sides, thereby adapting to the material conveying process of silos of different lengths.
