[0011] Preferably, a runner is in contact with the outer wall of the granulating roller. One side of the runner is fixedly connected to a rotating rod, and the outer wall of the rotating rod is fixedly connected with bristles, and the bristles are used to play a role in stirring and compacting the particles.

[0012] Preferably, a support sleeve is rotatably connected to the outer wall of the runner. The bottom of the support sleeve is fixedly connected with a sliding plate, and the outer wall of the sliding plate is slidably connected to a fixed sleeve, and the bottom of the fixed sleeve is fixedly connected inside the granulator.

[0013] Preferably, an internal spring is arranged inside the fixed sleeve, and the inner wall of the fixed sleeve is slidably connected with a sliding plate.

[0014] Preferably, a feeding mechanism is arranged on the outer wall of the sliding plate. The feeding mechanism includes a fixed seat, the fixed seat is fixedly connected to the outer wall of the sliding plate, a sliding frame is slidably connected to the outer wall of the fixed seat, and a pull rope is fixedly connected to the outer wall of the sliding frame.

[0015] Preferably, magnetic grooves are formed on the outer wall of the granulating roller. The magnetic grooves and the runner have magnetism, and the magnetism on the side where the magnetic grooves and the runner approach each other is the same pole repulsion.

[0016] Preferably, an auxiliary mechanism is arranged on the outer wall of the fixed seat.

[0017] The present invention provides a crushing and forming granulating device for producing crop particle fuel. It has the following beneficial effects:

[0018] 1. By setting the feeding mechanism in the present invention, when the particles fall off from the groove, the air inside the groove will be communicated with the outside through the air groove and the air pipe, and air is obtained from the outside to supplement the groove, which can reduce the negative pressure caused by the falling off of the particles in the groove and improve the particle feeding efficiency.

[0019] 2. By setting the feeding mechanism in the present invention, when the runner rotates, it will drive the rotating rod and the bristles to rotate synchronously. The rotation of the bristles gently stirs the particles in the upper groove, so that the particles stuck in the groove can be stirred and fall off, thereby completing stable particle detachment work and reducing the phenomenon of being stuck inside the groove and unable to fall off.

[0020] 3. By setting the feeding mechanism in the present invention, through its uniform falling method, it can reduce the problem of particles accumulating in groups with each other, and can also use several pull ropes to complete the screening of the particles, prevent larger non-conforming particles from falling, and play a role in screening them.

[0021] 4. By providing an auxiliary mechanism in the present invention, the skateboard slides down along the inner wall of the fixed sleeve, and the rotating wheel also descends. As the magnetic groove disengages from the rotating wheel, the rotating wheel rebounds under the action of the built-in spring inside the fixed sleeve, thereby realizing the vibration of the brush bristles, shaking off the debris adhering to the surface of the brush bristles, and also driving the shaking of the pull rope on the fixed seat and the sliding frame, so that the pull rope vibrates, which can effectively lift the particles accumulated and adhered to the pull rope, ensuring its stable falling and screening effect.

[0022] 5. By providing an auxiliary mechanism in the present invention, the up-and-down vibration frequency of the pull rope can be further increased through the vibration of the sliding frame, further enhancing the efficiency of the pull rope for evenly screening and discharging particles, and reducing the problem that particles cannot be discharged due to mutual adhesion and jamming caused by the moisture contained therein.

[0023] 6. By providing an auxiliary mechanism in the present invention, the particles falling between each pull rope will deflect the pull rope to swing left and right to deform it, accelerating the discharging speed of the particles. Then, under this state, it is possible to ensure that the discharging speed is sufficient as much as possible, and slightly reduce the screening accuracy to ensure that the particles can be effectively and evenly discharged while ensuring high efficiency, and at the same time, the problem of mutual congestion, accumulation and adhesion into a group due to limited discharging speed will not occur.

DETAILED DESCRIPTION

[0036] Example 1: Please refer to Figures 1-4 The present invention provides a technical solution: a crushed material forming and granulating device for producing crop pellet fuel, comprising a granulator 1, a discharge port 5 is arranged at the bottom of the granulator 1, and a granulating mechanism 2 is arranged inside the granulator 1;

[0037] The granulation mechanism 2 comprises:

[0038] Granulating roller 201, granulating roller 201 is a circular cylindrical structure, both ends of granulating roller 201 are fixedly connected with rotating shaft 6, one end of rotating shaft 6 is fixedly connected with the inner wall of granulating machine 1, there are two granulating rollers 201, granulating roller 201 is used to be driven by granulating machine 1 through rotating shaft 6 to rotate;

[0039] The groove 202 is a hemispherical groove, which is provided on the outer wall of the granulating roller 201 , and an air groove 203 is provided on the inner wall of the groove 202 . An air pipe 204 is rotatably connected to one side of the granulating roller 201 , and the groove 202 is used to compact the crushed material.

[0040] The interior of the air pipe 204 is communicated with the interior of the granulating roller 201 , and the interior of the granulating roller 201 is communicated with the interior of the air groove 203 .

[0041] The outer wall of the granulating roller 201 contacts with a rotating wheel 205 , one side of the rotating wheel 205 is fixedly connected with a rotating rod 206 , and the outer wall of the rotating rod 206 is fixedly connected with bristles 207 , which are used to move and compact the particles.

[0042] A support sleeve 208 is rotatably connected to the outer wall of the runner 205. A slide plate 209 is fixedly connected to the bottom of the support sleeve 208. The outer wall of the slide plate 209 is slidably connected to a fixed sleeve 210, and the bottom of the fixed sleeve 210 is fixedly connected inside the granulator 1.

[0043] An internal spring is provided inside the fixed sleeve 210, and the slide plate 209 is slidably connected to the inner wall of the fixed sleeve 210;

[0044] During use, the crushed material is put into the granulator 1, and then the granulator 1 is started to control the rotation of the two rotating shafts 6 and the two granulating rollers 201, so as to complete the mutual rotation of the two granulating rollers 201. By using the mutually opposite rotation directions and the concave grooves 202 on the granulating rollers 201, the crushing material is compacted into particles. After the agricultural crop crushing material is compressed, it drops as the granulating roller 201 continues to rotate, and is discharged through the discharge port 5;

[0045] When the granulating roller 201 rotates and compresses, the crushed material extruded inside the groove 202 will become granular. When the groove 202 is driven by the rotation of the granulating roller 201 to the lower part, the particles inside the groove 202 will naturally drop due to gravity, completing the discharge and separation. At the same time, when the particles fall off from the groove 202, the air inside the groove 202 will communicate with the outside through the air grooves 203 and the air pipes 204, and air is obtained from the outside to be replenished into the groove 202, which can reduce the negative pressure caused by the particle falling off in the groove 202 and improve the particle feeding efficiency;

[0046] When the granulating roller 201 rotates, it will contact the lower runner 205 and drive the runner 205 to rotate through friction. When the runner 205 rotates, it will rotate inside the inner wall of the support sleeve 208. The support of the support sleeve 208 for the runner 205 ensures that the rotation of the runner 205 is unobstructed;

[0047] At the same time, when the runner 205 rotates, it will drive the rotating rod 206 and the brush hairs 207 to rotate synchronously. The rotation of the brush hairs 207 is used to gently stir the particulate matter in the upper groove 202, so that the particulate matter trapped in the groove 202 can be stirred and fall off, thereby completing the stable particle separation work and reducing the phenomenon that the particulate matter is trapped and adhered inside the groove 202 and cannot fall off;

[0048] Embodiment 2: Please refer to Figures 1-9 , on the basis of Embodiment 1, the present invention provides a technical solution: a feeding mechanism 3 is provided on the outer wall of the slide plate 209. The feeding mechanism 3 includes a fixed seat 301, the fixed seat 301 is fixedly connected to the outer wall of the slide plate 209, a sliding frame 302 is slidably connected to the outer wall of the fixed seat 301, and a pulling rope 303 is fixedly connected to the outer wall of the sliding frame 302.

[0049] The outer wall of the granulating roller 201 is provided with magnetic grooves 304. The magnetic grooves 304 and the runner 205 have magnetism, and the magnetism on the side where the magnetic grooves 304 and the runner 205 are close to each other repels with the same pole;

[0050] The particulate matter falling through the groove 202 will contact the lower drawstrings 303 and be blocked by several drawstrings 303, so that each particulate matter can be evenly distributed on each drawstring 303 and fall through the gaps between each drawstring 303, realizing the uniform distribution and falling of the particulate matter concentratedly fed in the middle of the two granulating rollers 201 through the planar drawstrings 303, ensuring the uniformity of falling, enabling the particulate matter to fully contact the air during the stable feeding process, quickly drying the pre-added moisture inside, and avoiding the problem of adhesion to the discharge port 5 when rolling in the lower discharge port 5 and thus being unable to roll down;

[0051] At the same time, through its uniform falling method, the problem of particulate matter accumulating in groups with each other can be reduced, and several drawstrings 303 can also be used to complete the screening of the particulate matter, preventing larger non-conforming particulate matter from falling and playing a screening role for it;

[0052] When the granulating roller 201 drives the magnetic grooves 304 to rotate, there are several magnetic grooves 304 on the outer wall of the granulating roller 201. When each magnetic groove 304 rotates to the position of the runner 205, the runner 205 will be repelled and pushed downward by the magnetic repulsion force between the magnetic groove 304 and the runner 205. Then the runner 205 pushes the support sleeve 208 and the slide plate 209 downward, causing the slide plate 209 to slide downward on the inner wall of the fixed sleeve 210 and squeezing the built-in spring inside the fixed sleeve 210 to deform. Thus, the slide plate 209 will slide downward on the inner wall of the fixed sleeve 210, and the runner 205 will descend. As the magnetic groove 304 moves away from the runner 205 relatively, the runner 205 rebounds by the built-in spring inside the fixed sleeve 210, and then realizes the shaking of the brush bristles 207, shakes off the crushed slag adhering to the surface of the brush bristles 207, and can also drive the drawstrings 303 on the fixed seat 301 and the sliding frame 302 to shake, so that the drawstrings 303 shake, which can effectively lift the particulate matter accumulated and adhered to the drawstrings 303 and ensure its stable falling and screening effect;

[0053] And as the fixed seat 301 vibrates up and down continuously, the sliding frame 302 on the outer wall of the fixed seat 301 will slide up and down synchronously on the fixed seat 301 along the slide bar 401;

[0054] It can further improve the up-and-down shaking frequency of the drawstrings 303 through the shaking of the sliding frame 302, further enhance the efficiency of the drawstrings 303 for evenly screening and feeding the particulate matter, and reduce the problem that the particulate matter cannot be fed due to mutual adhesion and jamming because of the moisture contained;

[0055] Example 3: Please refer to Figures 1-11 , on the basis of the first and second embodiments, the present invention provides a technical solution: an auxiliary mechanism 4 is arranged on the outer wall of the fixed seat 301, the auxiliary mechanism 4 comprises a slide bar 401, the outer wall of the slide bar 401 is fixedly connected to both sides of the fixed seat 301, a telescopic rod 402 is fixedly connected to the outer wall of the slide frame 302, a baffle 403 is fixedly connected to one end of the telescopic rod 402, the baffle 403 is fixedly connected to one side of the fixed seat 301, and a coarse one-way valve 404 and a fine one-way valve 405 are opened on the outer wall of the telescopic rod 402;

[0056] When the granulation roller 201 is accelerated to improve the granulation efficiency, the rotation speed of the granulation roller 201 is accelerated to accelerate the magnetic repulsion between the magnetic slot 304 and the rotating wheel 205, so that the fixed seat 301 on the slide plate 209 also accelerates the up and down vibration. At this time, more granulated particles will fall onto the pull rope 303. At this time, the sliding frame 302 will slide up and down on the fixed seat 301 and the sliding bar 401 at a faster frequency, and squeeze the air inside the telescopic rod 402 to be continuously discharged through the coarse one-way valve 404, and replenished from the fine one-way valve 405.

[0057] Since the aperture of the fine one-way valve 405 is much smaller than the coarse one-way valve 404, when the slide frame 302 descends and squeezes the telescopic rod 402, the air inside the telescopic rod 402 is quickly and unrestrictedly discharged through the coarse one-way valve 404. When the slide frame 302 vibrates and rises, the telescopic rod 402 is pulled, and the air inside the telescopic rod 402 can only be replenished through the fine one-way valve 405 with a smaller aperture. However, the fine one-way valve 405 is limited in replenishing air and the speed is slow. Therefore, under rapid vibration, the telescopic rod 402 will remain shortened more and rise less, and then the slide frame 302 will tend to the bottom position of the fixed seat 301 under the working state of rapid granulation.

[0058] Because one side of the fixed seat 301 is an inclined surface, when the sliding frame 302 moves to the position below the fixed seat 301, the distance between the sliding frames 302 at both ends of the pull rope 303 will be shortened, so that the tension of the pull rope 303 will be relaxed and become more curved, and each pull rope 303 will change from a straight state to a downward curve, so that the particles falling between each pull rope 303 will move the pull rope 303 to swing left and right to deform it, thereby accelerating the feeding speed of the particles, and then achieving the state in which the feeding speed is as sufficient as possible, and slightly reducing some screening accuracy, to ensure that the particles can be effectively and evenly dropped and screened under high efficiency, while not being crowded and piled up and sticking together due to the limited feeding speed.

[0059] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
