For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components.

[0034] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0035] Example 1

[0036] In order to improve the filling efficiency of polyacrylamide, this embodiment provides a new filling technology solution. When the filling equipment provided by this embodiment is used to fill polyacrylamide materials, the polyacrylamide materials can be loaded into multiple containers at one time, changing the way the filling equipment can only complete the filling of one container at a time, thereby relatively improving the filling efficiency of polyacrylamide.

[0037] like Figure 1 、 Figure 2As shown, specifically, the filling equipment mainly includes a bracket, a chain conveyor, a silo 3, a material distribution shell 4, a material distribution mechanism 5, etc. The chain conveyor is installed on the bracket and includes a conveyor chain 1, a supporting plate group 2, a motor, etc. The supporting plate group 2 is arranged above the conveyor chain 1 and is arranged along the width direction of the chain conveyor. In addition, multiple groups of supporting plate groups 2 are evenly distributed along the length direction of the conveyor chain 1. The motor is set to control the rotation of the conveyor chain 1 and thus control the synchronous movement of multiple groups of supporting plate groups 2. The material distribution shell 4 is set on the bracket and is located above the chain conveyor. The material distribution mechanism 5 is located in the material distribution shell 4. A motor is set on the outside of the material distribution shell 4. The purpose of the motor is to control the operation of the material distribution mechanism 5 and thus realize the separate transportation of materials. In order to realize the filling and processing of batch materials, the silo 3 is arranged above the material distribution shell 4. When the device is used to realize the filling of materials, batches of materials are accumulated in the silo 3. Under the action of the material distribution mechanism 5, the materials in the silo 3 are controlled to be quantitatively discharged multiple times from the lower end of the material distribution shell 4. In order to enable the material output from the material distribution shell 4 to form multiple strands and fall into multiple containers respectively, a pass bin 7 is provided below the material distribution shell 4, and multiple material control rods 6 are provided on the inner side of the pass bin 7. The multiple material control rods 6 rotate regularly under the control of the motor, so that the regular output of the material accumulated in the pass bin 7 can be controlled. In addition, a lower bin 8 is provided below the pass bin 7, and the inner space of the lower bin 8 is set as a frustum structure, and the lower end is set as a discharge hole 81. Multiple filling plates 9 are provided on the inner side of the lower bin 8. The two filling plates 9 are symmetrically arranged. With the cooperation of the multiple filling plates 9 and the inner space of the lower bin 8, multiple conical feeding spaces are formed. In addition, a gap 91 is formed between the two filling plates 9. The material in the feeding space is output from the gap 91 and falls into the container, thereby realizing the filling process of the material. In addition, in order to be able to control the operation of the device, a control box needs to be installed on the bracket. The control box is a prior art and will not be introduced in detail here. In short, the operation of each device can be controlled by the control box.

[0038] like Figure 3 As shown, in order to realize the disassembly and assembly of the material distribution mechanism 5, the material distribution shell 4 includes two end plates 41 and two side plates 42. The two side plates 42 are arranged in parallel. The two end plates 41 are connected by bolts and the like and can be detachably arranged at the two ends of the two side plates 42. Therefore, a detachable installation space is formed under the cooperation of the end plates 41 and the side plates 42, which provides convenience for disassembly, maintenance and replacement of the material distribution mechanism 5 according to needs.

[0039] like Figure 5As shown, to control the distribution mechanism 5 so that the batch material in the silo 3 falls into the distribution housing 4, the distribution mechanism 5 includes two central shafts 51 and multiple distribution pipes 52. The two central shafts 51 are arranged in parallel, with their ends extending through the distribution housing 4. The central shafts 51 are connected to the motor using conventional connection methods, such as a reduction gearbox, belt and pulley, chain and material wheel, etc. In short, the motor controls the two central shafts 51 to rotate in opposite directions. The multiple distribution pipes 52 are arranged in two groups, with the two groups of distribution pipes 52 paired one-to-one with the two central shafts 51, and each group includes multiple distribution pipes 52.

[0040] like Figure 6 、 Figure 7 As shown, in order to make the distribution pipe 52 statically installed relative to the center axis 51, a groove 511 is provided on the center axis 51, and the groove 511 is provided along the length direction of the center axis 51. A convex plate 523 is fixedly provided on the inner side of the distribution pipe 52, and the convex plate 523 is located at the groove 511. This arrangement can realize the relative static connection between the distribution pipe 52 and the center axis 51. At the same time, the two groups of distribution pipes 52 contact each other. In addition, a discharge trough 522 is provided on the distribution pipe 52. During the rotation of the distribution pipe 52, the discharge troughs 522 of the two contacting distribution pipes 52 in the two groups are regularly facing each other. When the discharge troughs 522 are facing each other, a channel for material falling is formed. At this time, the material will pass through the distribution pipe 52 and fall into the bin 7. When the discharge trough 522 deviates, the material can be limited to be stably stored in the bin 3, thereby realizing the regular output of the material.

[0041] like Figure 6 As shown, in order to prevent the distribution tube 52 from moving along the length direction of the central axis 51, a threaded groove 521 is provided on the end wall of the distribution tube 52, and a limiting bolt 524 can be threadedly inserted and immersed in the threaded groove 521. When the limiting bolt 524 is rotated, the end of the limiting bolt 524 presses against the central axis 51, increasing the resistance of the distribution tube 52 to the movement of the central axis 51, thereby achieving stable installation of the distribution tube 52.

[0042] like Figure 5 、 Figure 8 As shown, in order to prevent the material from moving to the outside of the distribution tube 52, the distribution mechanism 5 also includes two scrapers 53, which are respectively arranged obliquely above the two groups of distribution tubes 52, and the lower ends of the scrapers 53 are in contact with the distribution tube 52, and the upper ends are in contact with the top of the distribution shell 4. Therefore, under the action of the scraper 53, the gap between the distribution tube 52 and the distribution shell 4 is blocked to avoid affecting the quantitative filling of the material.

[0043] like Figure 5 、 Figure 8As shown, in order to form multiple independent unloading spaces in the distribution shell 4, multiple partition plates 54 are also arranged between the two scrapers 53. The multiple partition plates 54 are arranged along the length direction of the central axis 51 and are located in the gap between adjacent distribution pipes 52. At the same time, the lower end of the partition plate 54 extends into the pass bin 7, and the partition plate 54 contacts the side wall of the distribution shell 4. Therefore, under the action of the partition plate 54, the entire distribution shell 4 is divided into multiple independent spaces, and then the material discharged from the silo 3 is distributed in multiple independent spaces. When the distribution pipe 52 acts, the material in the multiple independent spaces falls quantitatively into the pass bin 7 and the lower bin 8, and finally is output from the gap 91 and falls into the filling container.

[0044] like Figure 8 As shown, in order to make the partition plate 54 and the scraper 53 stably and detachably connected, a second connecting groove 541 is provided at the top of the partition plate 54, and a first connecting groove 531 is provided at the lower end of the scraper 53. The partition plate 54 is detachably connected to the partition plate 54 through the first connecting groove 531 and the second connecting groove 541. Therefore, a plurality of independent spaces are formed with the cooperation of the scraper 53 and the partition plate 54.

[0045] like Figure 9 、 Figure 10 、 Figure 11 As shown, in order to control the descent of the material in the bin 7 by the material control rod 6, a plurality of material control rods 6 are arranged adjacent to each other in the bin 7, and the plurality of material control rods 6 are alternately distributed with the plurality of partition plates 54, that is, the ends of adjacent material control rods 6 are fitted with the partition plates 54. In addition, a transmission shaft 542 is provided through the lower end of the partition plate 54, and a polygonal groove 61 is provided on the end face of the material control rod 6. The end of the transmission shaft 542 is inserted into the polygonal groove 61. Therefore, with the cooperation of the transmission shaft 542 and the polygonal groove 61, the adjacent material control rods 6 can rotate synchronously. In this case, the end of the material control rod 6 located on the outside needs to protrude from the bin 7 and be connected to the motor. The connection method is the existing technology and will not be introduced here. Therefore, under the action of the motor, the material control rod 6 rotates regularly. In order to realize the discharge of materials during the regular rotation of the material control rod 6, a material discharge hole 62 is provided on the material control rod 6. Therefore, when the material discharge hole 62 contacts the material, the material will drop along the material discharge hole 62 and fall into the lower bin 8.

[0046] Example 2

[0047] like Figure 1 、 Figure 4As shown, on the basis of Example 1, in order to control the stable placement of multiple containers and move them to the bottom of the lower warehouse 8, and at the same time, multiple containers are aligned with the multiple gaps 91 of the lower warehouse 8, the supporting plate group 2 includes a bottom plate 21 and two clamping plates 22, and a plurality of snap grooves 23 are provided on the upper side of the bottom plate 21. Each two snap grooves 23 are symmetrically distributed about the central axis of the bottom plate 21, and their ends away from each other are set as openings. A bidirectional screw 25 is provided through the two snap grooves 23, and a snap plate 24 is fixedly provided under the clamping plate 22. The snap plate 24 is located in the snap groove 23. Therefore, the clamping plate 22 is stably and movably installed relative to the bottom plate 21, wherein the bidirectional screw 25 is threaded through the snap plate 24, and a polygonal groove is provided on the end face of the bidirectional screw 25. Therefore, the polygonal wrench can be inserted into the polygonal groove to control the rotation of the bidirectional screw 25, thereby changing the relative position of the two clamping plates 22 to achieve the restriction of the container position.

[0048] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
