Description

Technical Field

[0001] The utility model relates to the technical field of material conveying structures, in particular to a micro-motion control mechanism and a pipeline chain plug disc conveying system. Background Art

[0002] Delivering feed to livestock is an essential part of animal husbandry. The method of directly feeding feed to livestock by hand has been gradually replaced by mechanical delivery due to its low efficiency and high labor costs.

[0003] In the existing particle material conveying system, the pipeline chain plug-disk conveying method is commonly used. This type of conveying has low initial investment cost, high conveying efficiency and simple maintenance. The basic principle is to use the driving wheel on the traction host to pull the plug-disk chain in the pipeline to circulate and transport the material from the storage device to the end of the system.

[0004] However, during the conveying process, material jams often occur. After the jam, the disk chain cannot move, while the traction main machine continues to provide power, which can easily cause the disk chain to break and damage the equipment. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a micro-motion control mechanism and a pipeline chain plug disc conveying system to solve the problem in the prior art that the plug disc chain cannot move during the material jamming process, while the traction main machine keeps providing power, which easily causes the plug disc chain to break and equipment damage.

[0006] To achieve the above-mentioned object, the utility model adopts the following technical solutions on one hand: a micro-motion control mechanism, including an adjusting wheel installed in a pipeline and used to engage with a plug disc chain;

[0007] The regulating wheel is provided with a counting part for recording the number of rotations per unit time. The counting part is also connected to a controller for connecting to the traction host. The controller is used to read the data in the counting part and compare it with the preset data value to determine the operating status of the traction host.

[0008] On the other hand, the utility model adopts the following technical solution: a pipeline chain plug-disk conveying system, including the above-mentioned micro-motion control mechanism.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. When the chock chain operates normally, the regulating wheel in the micro-control mechanism rotates normally with the chock chain; when the chock chain cannot move due to material jamming, the counting unit records that the number of revolutions of the regulating wheel per unit time is much smaller than the data value preset in the controller. At this time, the controller stops the traction host to protect the traction host and the equipment; the staff can then repair the jamming phenomenon.

[0011] 2. This pipeline chain plug conveying system can stop the traction host when the plug chain cannot move due to material jamming, so as to protect the traction host and equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The figure marks in the drawings of the specification include: pipeline 1, driving wheel 2, traction main machine 3, adjusting wheel 4, counting part 5, mounting column 51, transmission column 52, adjusting rod 53, limiting notch 54, counting structure 55, fixing cylinder 551, push rod 552, control wheel 6, protective cover 7. DETAILED DESCRIPTION

[0016] The utility model is further described in detail below through specific implementation methods:

[0017] like Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes a pipeline chain plug disc conveying system, including a pipeline 1, a driving wheel 2 rotatably arranged in the pipeline 1, a plug disc chain (not shown) arranged in the pipeline 1 and meshing with the driving wheel 2, a traction main machine 3 connected to the driving wheel 2, and a micro-control mechanism arranged on the pipeline 1 and cooperating with the plug disc chain.

[0018] Among them, the traction host 3 can be a motor; the traction host 3 runs to provide power for the rotation of the driving wheel 2, and the driving wheel 2 rotates to drive the disk chain of the disk chain to circulate and transport the material from the storage device to the end of the system; when the material is stuck and the disk chain cannot move, the micro-control mechanism stops the operation of the traction host 3 to protect the traction host 3 and the system.

[0019] The system may also include other existing structures such as a driven wheel that cooperates with the plug chain. Here, a micro-motion control mechanism is mainly designed to stop the operation of the traction host 3 when the plug chain cannot move due to material jamming, so as to protect the traction host 3 and the system.

[0020] In order to understand the pipeline chain plug conveying system in detail, the micro-control mechanism is further refined below. Figure 1 -- Figure 3 As shown, according to another embodiment of the utility model, the micro-control mechanism includes an adjusting wheel 4 installed in the pipeline 1 and used to engage with the plug chain; the adjusting wheel 4 is equipped with a counting part 5 for recording the number of rotations per unit time, and the counting part 5 is also connected to a controller (not shown) for connecting to the traction host 3, and the controller is used to read the data in the counting part 5 and compare it with the preset data value to determine the operating status of the traction host 3.

[0021] In the present utility model: during normal operation, the regulating wheel 4 rotates normally with the jamming disk chain; when the jamming disk chain cannot move due to the occurrence of jamming, the counting unit 5 records that the number of revolutions of the regulating wheel 4 per unit time is much smaller than the data value preset in the controller, and the controller stops the traction host 3 at this time to protect the traction host 3 and the equipment; the staff can inspect and repair the jamming phenomenon. For example: during normal operation, the regulating wheel 4 rotates 20-30 times per unit time, and the preset data value can be designed to rotate 6 times per unit time. When the controller obtains that the number of revolutions of the regulating wheel 4 collected by the counting unit 5 per unit time is less than 6 times, it means that the jamming phenomenon is serious, and the controller issues an instruction to stop the operation of the traction host 3 to avoid damage to the traction host 3 and the system. And the preset data value in the controller can be reasonably adjusted according to the actual situation, and the controller can be CPU.

[0022] Based on the above scheme:

[0023] The regulating wheel 4 is coaxially connected to the control wheel 6, and the control wheel 6 is arranged outside the pipeline 1, and the counting part 5 cooperates with the control wheel 6. Here, the control wheel 6 is coaxially connected to the regulating wheel 4, and the control wheel 6 rotates synchronously with the regulating wheel 4. The counting part 5 records the number of revolutions of the control wheel 6 in a unit time, that is, the number of revolutions of the regulating wheel 4 in a unit time; the counting part 5 and the control wheel 6 are arranged outside the pipeline 1, and will not affect the normal work in the pipeline 1.

[0024] In order to protect the counting part 5 and the control wheel 6 , a protective cover 7 is provided on the outer wall of the pipeline 1 , and the control wheel 6 and the counting part 5 are both arranged in the protective cover 7 .

[0025] The structure of the counting unit 5 will be detailed below to facilitate further understanding of the micro-motion control mechanism. Figure 2 and Figure 3 As shown, according to another embodiment of the utility model, a micro-control mechanism, wherein the counting part 5 includes a mounting column 51, a transmission column 52, an adjusting rod 53 and a counting structure 55; wherein the mounting column 51 is fixedly connected to the outer wall of the pipeline 1 and is located outside the control wheel 6, and a limiting notch 54 is provided on the mounting column 51; the transmission column 52 is fixedly connected to the edge of the control wheel 6; one end of the adjusting rod 53 is rotatably connected in the limiting notch 54 through a rotating reset structure and the other end thereof intermittently resists the transmission column 52 to swing back and forth; the counting structure 55 cooperates with the adjusting rod 53 and is also connected to the controller, and is used to record the number of reciprocating swings of the adjusting rod 53 per unit time.

[0026] In this utility model:

[0027] When the adjusting wheel 4 rotates with the movement of the plug chain, the control wheel 6 rotates synchronously with the adjusting wheel 4, and the transmission column 52 rotates with the control wheel 6 to make the adjusting rod 53 swing back and forth in the limiting gap 54, and the counting structure 55 records the number of reciprocating swings of the adjusting rod 53. Because the adjusting rod 53 swings back and forth once for each rotation of the adjusting wheel 4, the counting structure 55 records the number of reciprocating swings of the adjusting rod 53 in unit time, which also records the number of rotations of the adjusting wheel 4 in unit time. The limiting notch 54 provides a movable space for the reciprocating swing of the adjusting rod 53, so that the adjusting rod 53 can rotate stably; wherein, the rotation reset structure can be a matching rotating shaft and torsion spring, which is an existing matching structure, so that the transmission column 52 rotates with the control wheel 6, and the free end of the transmission column 52 and the adjusting rod 53 abuts against each other to rotate the adjusting rod 53, and then the transmission column 52 and the adjusting rod 53 are disengaged from each other, and the adjusting rod 53 is reset under the action of the rotation reset structure, and the limiting notch 54 is matched to limit the initial position back and forth, waiting for the next cooperation with the transmission column 52.

[0028] Based on the above scheme:

[0029] The counting structure 55 includes a fixed cylinder 551 and a push rod 552; wherein the fixed cylinder 551 is fixedly set in the limiting notch 54 and a counter is arranged therein, and the counter is connected to the controller; one end of the push rod 552 is slidably set in the fixed cylinder 551 and cooperates with the trigger end of the counter, and the push rod 552 is also connected to an elastic support member for resetting it, and the other end of the push rod 552 is located on the swing path of the adjusting rod 53.

[0030] When the adjusting wheel 4 rotates with the movement of the plug chain, the control wheel 6 rotates synchronously with the adjusting wheel 4, and the transmission column 52 rotates with the control wheel 6 to make the adjusting rod 53 swing back and forth in the limiting notch 54. The adjusting rod 53 swings back and forth once to make the push rod 552 slide back and forth once, and the push rod 552 hits the trigger end of the counter once, and the counter records a number once; the elastic support member resets the push rod 552 to wait for the next cooperation with the adjusting rod 53; the counter can be an existing electronic counter, and the elastic support member can be a spring. The controller collects the count of the electronic counter once each time, and then the controller calculates the number of calculations of the counter in unit time, which is the number of rotations of the adjusting wheel 4 in unit time. The collected number of rotations of the adjusting wheel 4 per unit time is compared with the preset data value to determine the operating status of the traction host 3. When the collected number of rotations of the adjusting wheel 4 per unit time is not less than the preset data value, the traction host 3 continues to operate; when the collected number of rotations of the adjusting wheel 4 per unit time is less than the preset data value, the traction host 3 stops operating and the material jamming situation can be repaired.

[0031] Among them, the limiting notch 54 is formed by two cross-connected inclined walls on the free end of the mounting column 51; specifically, the two inclined walls are arranged in a V-shape, and when the adjusting rod 53 abuts against one of the inclined walls, the adjusting rod 53 is in the initial position, and the adjusting rod 53 does not abut against the transmission column 52.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
