Description

Technical Field

[0001] The invention relates to the technical field of trough feeders, in particular to a trough feeder with uniform material discharge. Background Art

[0002] Trough feeder is also called reciprocating or swing feeder. There are many types. The common feature of their structure is that they are all equipped with an adjustable gate to control the height of the material layer. At the bottom of the trough is a feeding plate that moves back and forth. The feeding plate is driven by a driving mechanism (usually a crank rotary drive) to achieve reciprocating movement, shaking and swinging, thereby pushing the material out to achieve the purpose of feeding.

[0003] In the prior art, the Chinese utility model patent with announcement number CN217867034U discloses a trough feeder, which relates to the technical field of feeders and includes a base, a mounting plate, a hopper, and a bottom plate; the hopper is fixedly connected to the top of the base by multiple fixing rods; a support rod is fixedly connected to one side of the upper surface of the base, and one side of the mounting plate is pivotally connected to the upper end of the support rod, and a slider is slidably connected to the other side of the upper surface of the base, and a first connecting rod is pivotally connected to both sides of the slider, and the other side of the mounting plate is pivotally connected to the upper end of the first connecting rod, and the slider is connected to a position adjustment mechanism; a plurality of support assemblies are fixedly connected to the upper surface of the mounting plate, and the bottom plate is slidably connected to the plurality of support assemblies, and the bottom plate is placed under the hopper; the threaded cylinder is axially moved by starting the second motor, and the slider is driven to move by the push-pull rod. The movement of the slider can tilt the mounting plate, and then the inclination angle of the bottom plate is changed, so as to adjust the inclination angle of the bottom plate according to different materials.

[0004] The above-mentioned device utilizes the forward and backward movement of the bottom plate to achieve the purpose of feeding during use. However, in actual use, the feeder has many application scenarios. When applied to feeding ore, the surface of the ore will be contaminated with a large amount of dust after mining. The friction between the ores during feeding will generate a large amount of dust. The above-mentioned device cannot handle the dust, and the dust will pollute the surrounding environment.

[0005] In the prior art, a Chinese utility model patent with the announcement number CN213355880U discloses a double-bottom-plate trough feeder, which relates to the technical field of trough feeders and includes a base frame, wherein the base frame is movably connected to rollers through a support frame, the tops of the rollers are in contact with the second base plate and the first base plate, and the top of the base frame is fixedly connected to a reducer through a connecting base. The utility model is capable of transmitting the power of the motor to the first base plate and the second base plate respectively through the first connecting rod and the second connecting rod by setting a reducer, so that the first base plate and the second base plate can reciprocate asynchronously, thereby achieving the purpose of alternately conveying materials, thereby achieving continuous material conveying, and by setting rollers, the first base plate and the second base plate can be well supported, and reciprocating motion can be achieved under the drive of the reducer. Since the two base plates are installed in opposite directions, the two base plates have relative motion, so that the conveyed materials have friction in different directions, thereby achieving the purpose of preventing the materials from sticking to the base plates.

[0006] As another example in the prior art, the Chinese utility model patent with announcement number CN208648055U discloses a new type of trough feeder, including a mounting plate, the upper surface of which is provided with a plurality of mounting holes, the upper surface of the mounting plate is fixedly connected to the lower surface of the U-shaped plate, the upper surface of the inner wall of the U-shaped plate is fixedly connected to the upper surface of the connecting plate through two electric push rods, and the lower surface of the connecting plate is fixedly connected to the top ends of the four pulleys.

[0007] During use, the above-mentioned device uses the bottom plate to drive the material to move back and forth. There is no other way of movement in this process, so the overall vibration amplitude of the material is small. After a large amount of material is put in, it is difficult to disperse evenly without effective vibration, which will cause uneven feeding. Summary of the Invention

[0015] Preferably, a rotating shaft for driving the rotation thereof is coaxially fixedly mounted on the lower end of the dust collector head, and a driven bevel gear is fixedly mounted on the bottom end of the rotating shaft.

[0016] Preferably, the driven bevel gear and the driving bevel gear form a meshing transmission structure, and the driving bevel gear and the leftmost supporting roller are coaxially fixedly installed.

[0018] Preferably, a cleaning scraper located inside the collection box is fixedly installed below the connecting rod, and the cleaning scraper is in contact with the upper surface of the dust filter, and a return spring located outside the collection box is installed on the outer side of the left end of the connecting rod.

[0019] Preferably, a longitudinal sliding structure is formed between the vibration plate and the pusher bottom plate, and a vibration spring is fixedly installed between the lower surface of the vibration plate and the inside of the pusher bottom plate.

[0020] Preferably, a knocking block for knocking the vibration plate is provided between the vibration plate and the support base, and a first airbag is fixedly installed between the knocking block and the support base, and the knocking block forms a lifting structure through the first airbag and the support base.

[0021] Preferably, the first airbag forms a communication structure with the second airbag fixedly installed on the upper surface of the left end of the pushing base plate through a connecting hose installed on its side, and the second airbag and the trough hopper squeeze each other.

[0022] Preferably, a height-limiting gate for limiting the discharge height is installed on the right side of the trough hopper, and positioning holes are opened at equal intervals on the side of the height-limiting gate, and the height-limiting gate is fixedly installed through the positioning holes using fixing bolts.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the trough feeder with uniform material discharge adopts a new structural design, the specific contents of which are as follows:

[0024] 1. A dust removal mechanism is set up. During the operation of the device, a negative pressure air pump is used to generate negative pressure in the dust collector head. The negative pressure is then used to transport the dust generated during operation to the collection box through a conveying hose. The dust is then filtered using a dust filter in the collection box, ultimately achieving the purpose of dust collection and preventing dust from flying around and affecting the surrounding environment.

[0025] Furthermore, the movement of the pushing bottom plate drives the supporting roller to rotate, thereby causing the supporting roller to drive the driving bevel gear to rotate. At this time, the meshing between the driving bevel gear and the driven bevel gear drives the rotating shaft to rotate, thereby causing the rotating shaft to drive the upper end of the dust collector to rotate back and forth, so that the dust collector forms a sector-shaped area, thereby expanding the overall dust collection range and achieving a better dust removal effect.

[0026] Furthermore, during the rotation process, the rotating shaft drives the extrusion cam fixed coaxially at its lower end to rotate synchronously, so that the extrusion cam is used to squeeze the connecting rod, so that the connecting rod drives the cleaning scraper to move left and right on the upper surface of the dust filter, cleaning the upper surface of the dust filter, and avoiding clogging of the dust filter during long-term use.

[0027] 2. During the reciprocating movement of the pushing bottom plate, the second airbag and the trough hopper are squeezed against each other, so that the air in the second airbag is injected into the first airbag through the connecting hose. The expansion of the first airbag pushes the knocking block to knock on the vibration plate. Since the vibration plate and the pushing bottom plate slide against each other and a vibration spring is provided, the vibration plate strengthens the vibration of the material inside the trough hopper, so that the material is quickly and evenly dispersed.

[0028] 3. A height-limiting gate is set at the discharge position of the trough hopper. The height-limiting gate is installed by fixing bolts. The fixing bolts change the installation position of the height-limiting gate by cooperating with the positioning holes in different positions, thereby limiting the height of the material when discharging, so as to adapt to different usage scenarios.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5In order to solve the problem of dust pollution in the use of traditional devices, this embodiment provides the following technical solutions: a dust removal mechanism is set up, and the dust removal mechanism is used to absorb dust during the operation of the device to prevent the device from flying around. Specifically disclosed: a horizontally installed support base 1, a mounting frame 2 with a frame structure is fixedly welded above the support base 1, a trough hopper 3 is fixedly welded on the inside of the mounting frame 2, and a pushing base plate 4 is fitted under the trough hopper 3. A driving turntable 5 is rotatably installed on the left side of the upper surface of the support base 1, and the driving turntable 5 is driven by a servo motor 6 through a belt to rotate, and a pushing rod 7 rotatably connected to the pushing base plate 4 is rotatably installed on the side edge of the driving turntable 5. The front and rear sides of the upper surface of the support base 1 rotate A support roller 8 for supporting the pushing base plate 4 is dynamically installed. A dust removal mechanism for absorbing dust raised during feeding is provided on the front and rear sides of the trough hopper 3. The dust removal mechanism includes a dust suction head 9 located above the trough hopper 3 and a collecting box 10 fixedly installed on the outer surface of the trough hopper 3. The dust suction head 9 forms a connecting structure with the collecting box 10 through a conveying hose 11, and a negative pressure air pump 12 is fixedly installed at the bottom end of the conveying hose 11, and a horizontally arranged dust filter 13 is fixedly installed at the lower end of the collecting box 10. A height limiting gate 21 for limiting the discharge height is installed on the right side of the trough hopper 3, and positioning holes 22 are opened at equal intervals on the side of the height limiting gate 21. The height limiting gate 21 is fixedly installed through the positioning holes 22 using fixing bolts 23.

[0043] When using the device, first fix the device in a designated place, then loosen the fixing bolts 23 according to the material to be transported, move the height-limiting gate 21 up and down, so that the height-limiting gate 21 moves to the required height, then insert the fixing bolts 23 into the corresponding positioning holes 22 and fix them, then the material to be transported enters the trough hopper 3, and at the same time start the servo motor 6. After the servo motor 6 is turned on, the drive turntable 5 rotates through the belt, and the drive turntable 5 drives the side push rod 7 to move back and forth, thereby using the push rod 7 to drive the pushing base plate 4 to move back and forth (the pushing base plate 4 is supported by the supporting roller 8 below). During the movement of the pushing base plate 4 back and forth, the material in the trough hopper 3 is continuously transported forward to achieve the purpose of feeding. During the feeding process, the negative pressure air pump 12 is turned on, and the negative pressure air pump 12 is used to generate negative pressure in the dust suction head 9. Under the action of the negative pressure, the dust is sucked in, and the dust passes through the conveying hose 11 into the collection box 10. The dust is filtered by the dust filter 13 in the collection box 10, and finally the dust is collected in the collection box 10.

[0044] Example 2: Please refer to Figure 3 、 Figure 6 and Figure 7In order to increase the use effect of the dust removal mechanism, this embodiment provides the following technical solutions. During the operation of the dust removal mechanism, the mechanism reciprocates to increase the overall dust collection range. Specifically, the following technical solutions are disclosed: a rotating shaft 14 for driving the rotation of the dust removal head 9 is coaxially fixedly installed at the lower end of the dust collection head 9, and a driven bevel gear 15 is fixedly installed at the bottom end of the rotating shaft 14. A meshing transmission structure is formed between the driven bevel gear 15 and the driving bevel gear 16, and the driving bevel gear 16 is coaxially fixedly installed with the leftmost support roller 8. An extrusion gear 16 is fixedly installed at the lower end of the rotating shaft 14 to rotate synchronously with the driving bevel gear 16. The pressure cam 17 is formed, and the position of the extrusion cam 17 and the connecting rod 18 on the side correspond to each other, and a through-type sliding structure is formed between the connecting rod 18 and the collecting box 10. A cleaning scraper 20 located inside the collecting box 10 is fixedly installed below the connecting rod 18, and the cleaning scraper 20 is in contact with the upper surface of the dust filter 13, and a return spring 19 located outside the collecting box 10 is installed on the outer side of the left end of the connecting rod 18. A vibration mechanism for generating longitudinal vibration during operation is provided on the upper surface of the support base 1, and the vibration mechanism includes a vibration plate 24 located on the inner side of the pushing bottom plate 4.

[0045] During the process of pushing the material pushing base plate 4 moving back and forth, the friction force is used to drive the supporting roller 8 below to rotate. During the rotation, the supporting roller 8 on the far left drives the active bevel gear 16 to rotate synchronously. At this time, the driven bevel gear 15 meshing with the active bevel gear 16 is used to drive the rotating shaft 14 to rotate. During the rotation, the rotating shaft 14 drives the dust suction head 9 to rotate reciprocatingly, so that the dust suction head 9 sweeps a sector area, thereby expanding the overall dust suction range. During the rotation, the rotating shaft 14 drives the extrusion cam 17 coaxially fixed at its lower end to rotate synchronously, and the extrusion cam 17 is used to squeeze the connecting rod 18. After being squeezed, the connecting rod 18 moves toward the inside of the collection box 10, and then the connecting rod 18 is reset under the elastic action of the reset spring 19. During this process, the connecting rod 18 moves back and forth left and right, and the connecting rod 18 drives the cleaning scraper 20 to move synchronously, and the cleaning scraper 20 is used to clean the upper surface of the dust filter 13 to avoid clogging of the dust filter 13 during long-term use.

[0046] Example 3: Please refer to Figures 8-11In order to solve the problem that the vibration amplitude of the traditional device is small and the material is unevenly dispersed during use, this embodiment provides the following technical solutions: a vibration mechanism is set, and the vibration mechanism is used to make the vibration plate 24 vibrate up and down, so that the material inside the trough hopper 3 is evenly dispersed. Specifically, it is disclosed that: a longitudinal sliding structure is formed between the vibration plate 24 and the pushing bottom plate 4, and a vibration spring 25 is fixedly installed between the lower surface of the vibration plate 24 and the inside of the pushing bottom plate 4, a knocking block 26 for knocking it is provided between the vibration plate 24 and the supporting base 1, and a first air bag 27 is fixedly installed between the knocking block 26 and the supporting base 1, and the knocking block 26 forms a lifting structure with the support base 1 through the first air bag 27, and the first air bag 27 forms a communication structure with the second air bag 29 fixedly installed on the upper surface of the left end of the pushing bottom plate 4 through the connecting hose 28 installed on its side, and the second air bag 29 and the trough hopper 3 are squeezed against each other.

[0047] As the pushing base plate 4 moves back and forth, the second airbag 29 on its upper surface is driven to move synchronously, so that the second airbag 29 and the trough hopper 3 are squeezed against each other. When the second airbag 29 is squeezed, the air inside enters the first airbag 27 through the connecting hose 28. At this time, the first airbag 27 expands and pushes the knocking block 26 to move upward to knock the vibration plate 24. Since the vibration plate 24 and the pushing base plate 4 are connected to each other in an up and down sliding manner, and a vibration spring 25 is arranged under the vibration plate 24, the entire vibration plate 24 will vibrate back and forth, so that the material inside the trough hopper 3 is quickly and evenly dispersed.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
