Mobile forced feeder

Abstract

This utility model discloses a mobile forced feeder, belonging to the field of feeder technology. It includes a base, a hopper on the top of the base, a bracket fixedly connected to the bottom of the hopper, and a hydraulic cylinder for adjusting the height of the hopper installed on the top of the base. The output end of the hydraulic cylinder is fixedly connected to the bracket. Two crushing rollers are rotatably installed inside the hopper. Gears are connected to the same end of the two crushing rollers, and the two gears mesh. By setting two crushing rollers rotating in opposite directions inside the hopper, one crushing roller is driven to rotate by a drive component, and the other crushing roller is driven to rotate synchronously by the meshing transmission of the meshing components at both ends. This allows lumpy materials to be crushed into small particles or a loose state by the squeezing and shearing action of the crushing rollers after entering the hopper, avoiding large pieces of material from directly entering the discharge port at the bottom of the hopper and causing physical blockage. This solves the blockage problem caused by the lack of crushing structure in existing equipment.

Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, and in particular to a mobile forced feeding machine. Background Technology

[0002] A feeder is a mechanical device used in automated or semi-automated production processes to uniformly and continuously transport bulk, granular, or lumpy materials to downstream equipment at a preset speed and flow rate. It achieves precise feeding through various structures such as vibration, belts, screws, and scrapers, preventing material accumulation or supply interruptions and allowing for control of production rhythm by adjusting parameters. It is widely used in industries such as manufacturing, agriculture, and mining, and particularly in the plastics processing sector, where it is used to feed plastic granules into extruders for processing.

[0003] In the prior art, there is a Chinese utility model patent with publication number "CN210011289U" and patent name "Mobile Feeding Machine". This patent discloses a mobile and forced feeding machine. The patent describes a technical solution including "a frame, a conveying device set on the frame and a control device set in the frame; the conveying device includes a transverse conveying pipe set above the frame, a hopper set above the transverse conveying pipe and connected to the transverse conveying pipe, a drive motor set at the rear end of the transverse conveying pipe and a screw connected to the drive motor and extending into the transverse conveying pipe, and the control device is electrically connected to the drive motor through a circuit".

[0004] Although the casters facilitate the movement and feeding of the entire device between different equipment, and the drive motor-driven screw rotation can force the material in the hopper to be fed to the downstream equipment, existing hoppers are mostly single conical or cylindrical structures. On the one hand, the inner wall of the hopper lacks an auxiliary structure to loosen the material, relying solely on the material's own gravity for feeding. When the material's flowability decreases, it is very easy to accumulate at the bottom of the hopper and the connection with the conveying pipe. On the other hand, the hopper is not equipped with crushing or dispersing components, making it impossible to pre-process lumpy materials or large impurities. This causes such materials to directly enter the discharge port, causing physical blockages. This not only requires manual shutdown for cleaning, reducing work efficiency, but also, in actual production, the inlet heights of downstream equipment vary. Existing fixed-height feeders need to be raised or modified to adapt, making operation cumbersome.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a mobile forced feeder. Utility Model Content

[0006] The main purpose of this invention is to provide a mobile forced feeder that can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A mobile forced feeder includes a base, the top of which is provided with a hopper;

[0009] A bracket is fixedly connected to the bottom of the hopper, and a hydraulic cylinder for adjusting the height of the hopper is installed on the top of the base. The output end of the hydraulic cylinder is fixedly connected to the bracket.

[0010] The hopper is equipped with two rotatable crushing rollers, and gears are connected to the same end of both crushing rollers, with the two gears meshing.

[0011] The hopper is also equipped with a drive component on one side for driving the crushing roller to rotate;

[0012] Inside the hopper and below the crushing roller, there is a crossbar that can move up and down. The bottom of the crossbar is fixedly connected to a reciprocating rod, and the reciprocating rod is equipped with a clearing rod for assisting in clearing the material in the base. One of the gears is connected to a connecting piece for driving the crossbar to move up and down.

[0013] Preferably, the bottom of the base is equipped with casters for moving the hopper, the bottom of the hopper is equipped with a feeding pipe for conveying materials, the inlet end of the feeding pipe is connected to the outlet end of the hopper, the inside of the feeding pipe is rotatably connected with a spiral blade, and one end of the feeding pipe is equipped with a first drive source for driving the spiral blade to rotate.

[0014] Preferably, rotating rods are fixedly connected to both ends of the crushing roller, and the rotating rods are rotatably connected to rotating holes opened on both sides of the hopper. The gear is fixedly connected to the other end wall of the rotating rod at one end of the crushing roller.

[0015] Preferably, the drive unit includes a second drive source mounted on one side of the hopper, and the output shaft of the second drive source is fixedly connected to a rotating rod at the end of one of the crushing rollers away from the gear via a coupling.

[0016] Preferably, a set of symmetrical guide plates are fixedly connected inside the hopper, and the guide plates are in an inclined state.

[0017] Preferably, the connector includes a connecting rod, with baffles fixedly connected to both ends of the crossbar. The baffles are slidably connected between a set of guide bars on both sides of the inner wall of the hopper. The guide bars are arranged on both sides of the guide opening. A pin is installed on the side of the baffle away from the crossbar. The pin is slidably connected to the guide opening on the side wall of the hopper. A pin is also fixedly connected to the eccentric side of one of the gears. Shaft holes for the pin to pass through are opened at both ends of one side of the connecting rod. A connecting rod to prevent the connecting rod from detaching is installed at the other end of the pin.

[0018] Preferably, the crossbar and the end baffles form an H-shape, and the baffles are used to block the inside of the guide opening.

[0019] Preferably, the unblocking rods are installed in a circular array at the bottom of the reciprocating rods, and the unblocking rods are inclined downwards.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By installing two opposing crushing rollers inside the hopper, one crushing roller is driven to rotate by a drive component, and the other crushing roller is driven to rotate synchronously by the meshing transmission of the meshing parts at both ends. This allows agglomerated materials (such as damp plastic granules and agglomerated mine waste) to be crushed into small particles or a loose state by the squeezing and shearing action of the crushing rollers after entering the hopper. This avoids large pieces of material directly entering the bottom discharge port of the hopper and causing physical blockage, thus solving the blockage problem caused by the lack of crushing structure in existing equipment.

[0022] Meanwhile, a crossbar that can reciprocate up and down is set below the crushing roller. The rotational motion of the meshing part is converted into the reciprocating motion of the crossbar through the connecting part between the eccentric side pin of the meshing part and the pin of the crossbar baffle. The reciprocating rod at the bottom of the crossbar moves synchronously with the crossbar, driving the inclined unblocking rods distributed in a ring array to continuously penetrate the material at the bottom of the hopper. This active unblocking structure can effectively break the "bridge" formed by the material at the bottom of the hopper and the connection of the feeding pipe, preventing the material from adhering and accumulating due to high viscosity or poor flowability. There is no need for manual shutdown for cleaning, which not only improves the continuity of feeding and avoids production interruption due to blockage, but also improves work efficiency.

[0023] Furthermore, by controlling the extension and retraction of the hydraulic cylinder, the overall height of the hopper can be flexibly adjusted. In actual production, there are differences in the inlet height of downstream equipment. This design allows for direct and rapid adjustment of the feeding height via the hydraulic cylinder without additional modifications, improving the equipment's adaptability to different production lines and reducing equipment replacement costs.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figure 1 - Figure 4 As shown, the mobile forced feeder includes a base 1, and a hopper 3 is provided on the top of the base 1;

[0031] A bracket 4 is fixedly connected to the bottom of the hopper 3, and a hydraulic cylinder 5 for adjusting the height of the hopper 3 is installed on the top of the base 1. The output end of the hydraulic cylinder 5 is fixedly connected to the bracket 4.

[0032] The hopper 3 is equipped with two crushing rollers 12 that rotate inside. Both crushing rollers 12 are connected to gears 14 on the same side end, and the two gears 14 mesh.

[0033] A drive unit for driving the crushing roller 12 to rotate is also provided on one side of the hopper 3;

[0034] Inside the hopper 3 and below the crushing roller 12, there is a horizontal bar 21 that can move up and down. The bottom of the horizontal bar 21 is fixedly connected to a reciprocating rod 22, and the reciprocating rod 22 is equipped with a clearing rod 23 for assisting in clearing the material in the base 1. A connecting piece for driving the horizontal bar 21 to move up and down is connected to one of the gears 14.

[0035] like Figure 1 and Figure 2As shown, the bottom of the base 1 is equipped with casters 2 for moving the hopper 3. The bottom of the hopper 3 is equipped with a feeding pipe 6 for conveying materials. The inlet end of the feeding pipe 6 is connected to the outlet end of the hopper 3. The inside of the feeding pipe 6 is rotatably connected with a spiral blade 7. One end of the feeding pipe 6 is equipped with a first drive source 8 for driving the spiral blade 7 to rotate. The casters 2 installed at the bottom of the base 1 enable the entire equipment to move flexibly and can be easily moved to the target downstream equipment. The feeding pipe 6 installed at the bottom of the hopper 3 has its inlet end connected to the outlet end of the hopper 3. The spiral blade 7 rotatably connected inside rotates under the drive of the first drive source 8. When the material falls from the hopper 3 into the feeding pipe 6, the rotating spiral blade 7 uses its own spiral structure to generate axial thrust on the material, forcibly conveying the material out, realizing forced and stable material conveying, ensuring that the material can accurately enter the downstream equipment, and ensuring the continuity of the production process.

[0036] like Figure 2 - Figure 4 As shown, rotating rods 13 are fixedly connected to both ends of the crushing roller 12. The rotating rods 13 are rotatably connected to the rotating holes 10 opened on both sides of the hopper 3. The gear 14 is fixedly connected to the other end wall of the rotating rod 13 at one end of the crushing roller 12. The driving component includes a second driving source 15 installed on one side of the hopper 3. The output shaft of the second driving source 15 is fixedly connected to the rotating rod 13 at the end of one of the crushing rollers 12 away from the gear 14 through a coupling. When the second driving source 15 is started, it drives the crushing roller 12 connected to it to rotate. Through the meshing transmission of the two gears 14, the other crushing roller 12 rotates in the opposite direction. The two crushing rollers 12 rotate in the opposite direction to crush the material. It can effectively squeeze and shear the agglomerated or large material, crushing it into loose small particles, which is convenient for subsequent conveying and processing, and improves the uniformity and processability of the material.

[0037] like Figure 2 and Figure 3 As shown, a set of symmetrical guide plates 9 are fixedly connected inside the hopper 3. The guide plates 9 are inclined, and their inclination angle guides the material fed into the hopper 3, causing the material to move towards the two crushing rollers 12 in the middle of the hopper 3. The guide plates 9 can effectively concentrate and guide the material to the crushing rollers 12, avoiding the material from being dispersed and accumulated in the hopper 3, improving the crushing efficiency of the crushing rollers 12, and ensuring that the material can be processed in a timely manner.

[0038] like Figure 3 and Figure 4As shown, the connector includes a connecting rod 19. Both ends of the crossbar 21 are fixedly connected to baffles 17. The baffles 17 are slidably connected between a set of guide bars 24 on both sides of the inner wall of the hopper 3. The guide bars 24 are located on both sides of the guide opening 11. A pin 16 is installed on the side of the baffle 17 away from the crossbar 21. The pin 16 is slidably connected to the guide opening 11 on the side wall of the hopper 3. A pin 16 is also fixedly connected to the eccentric side of one of the gears 14. Shaft holes 20 for the pin 16 to pass through are opened at both ends of one side of the connecting rod 19. A connecting rod 19 is installed at the other end of the pin 16 to prevent the connecting rod 19 from detaching. The crossbar 21 and the baffles 17 at both ends form an H-shape. The baffles 17 are used to block the inner side of the guide opening 11. The unblocking rods 23 are arranged in a ring array. The unblocking rod 23 is installed at the bottom of the reciprocating rod 22. It is inclined downwards, so that it can penetrate deeper into the material when it moves downwards and loosen the material when it moves upwards. When the gear 14 rotates, the pin 16 on its eccentric side drives the pin 16 on the side wall of the baffle 17 through the connecting rod 19, so that the baffle 17 slides up and down along the guide opening 11 on the side wall of the hopper 3, thereby driving the crossbar 21 to move up and down, so that the unblocking rod 23 continuously penetrates the material. The H-shaped crossbar 21 and the baffle 17 structure can prevent the material from leaking out of the guide opening 11. At the same time, the reciprocating motion of the unblocking rod 23 can effectively prevent the material from accumulating at the bottom of the hopper 3 and forming a bridge, ensuring the smooth falling of the material, reducing the possibility of material blockage, and improving the operating stability of the equipment.

[0039] Furthermore, to prevent the gear 14 and connecting rod 19 from being affected by external factors during operation or to avoid posing safety hazards to workers, a cover can be added to the outer wall of the hopper 3 to cover this part.

[0040] The specific operating principle of this mobile forced feeder is as follows:

[0041] In use, first move the equipment to the target downstream equipment using the casters 2 at the bottom of the base 1, then start the hydraulic cylinder 5. The extension and retraction of the hydraulic cylinder 5 will drive the support 4 at the bottom of the hopper 3 to rise and fall, adjusting the hopper 3 to a height that matches the feed inlet of the downstream equipment, and aligning the discharge end of the feed pipe 6 at the bottom of the hopper 3 with the feed inlet of the downstream equipment. Then, feed the material into the hopper 3. The inclined guide plate 9 inside the hopper 3 will guide the material to move towards the two crushing rollers 12 in the middle of the hopper 3. At this time, start the second drive source 15. The output shaft of the second drive source 15 drives the rotating rod 13 of one of the crushing rollers 12 to rotate in the rotating holes 10 on both sides of the hopper 3 through the coupling. Because the gears 14 on the rotating rods 13 at the same end of the two crushing rollers 12 mesh with each other, the other crushing roller 12 will rotate in the opposite direction. The two crushing rollers 12 rotate in opposite directions to squeeze and shear the material, breaking agglomerated or large pieces of material into loose small particles. When the crushed material falls to the lower part of the hopper 3, the connecting rod 19 is connected to the pin 16 through the shaft hole 20. This causes the crossbar 21, which is connected to the eccentric pin 16 of the gear 14 via the connecting rod 19, to push the pin 16 on the sidewalls of the end baffles 17 to slide up and down along the guide opening 11 on the sidewall of the hopper 3 under the rotation of the gear 14. The baffles 17 will move up and down between a set of symmetrical guide bars 24, and the crossbar 21 between the baffles 17 will move synchronously, driving the reciprocating rod 22 at the bottom to rise and fall synchronously. The inclined unclogging rods 23 of the bottom annular array continuously penetrate the material, preventing the material from accumulating at the bottom of the hopper 3 and forming bridging. Finally, the first drive source 8 is activated, which drives the spiral blades 7 in the feeding pipe 6 to rotate, forcibly conveying the material falling from the bottom of the hopper 3 into the feeding pipe 6 to the downstream equipment, completing the feeding operation. The H-shaped structure formed by the crossbar 21 and the baffle 17 can prevent the material from leaking out of the guide port 11, thereby avoiding the problem of material blockage in the hopper 3. There is no need for manual shutdown for cleaning, which improves production efficiency.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
