Description

Technical Field

[0001] This utility model relates to the field of pellet pressing machine technology, specifically to a giant reed straw pellet pressing machine. Background Technology

[0002] Giant reed grass, a high-yield and high-protein forage crop, plays a vital role in agricultural development through the resource utilization of its straw. Processing giant reed grass straw into pellets for easy storage, transportation, and use as feed or fuel is a common method of disposal.

[0003] Existing straw pellet presses typically use two opposing rotating pressing rollers to extrude and shape the powder. However, the powder is prone to blockage or uneven feeding at the feed inlet before entering the pressing rollers, resulting in a discontinuous forming process and affecting production efficiency. Furthermore, the pressed pellets are often of varying sizes, containing a large amount of insufficiently pressed powder or substandard pellets. If these substandard products are mixed with qualified products, it will reduce the overall product quality. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a giant reed straw pellet press. It solves the problem that the powder is prone to blockage or uneven feeding at the feed inlet before entering the pressing roller, resulting in discontinuous molding process and affecting production efficiency. Secondly, the pressed pellets are often of different sizes, containing a large amount of insufficiently pressed powder or unqualified pellets. If these unqualified products are mixed with qualified products, it will reduce the overall product quality.

[0005] To achieve the above objectives, this utility model provides a giant reed straw pellet press, comprising a hopper and a collection box. A connecting box is fixedly connected to the discharge port of the hopper, and a distributing box is fixedly connected to the upper end face of the collection box. An extrusion chamber is fixedly connected between the connecting box and the distributing box. A turnover groove is rotatably arranged in the connecting box, and a rotating shaft is fixedly connected to the turnover groove. Two pressing rollers are symmetrically rotatably arranged in the extrusion chamber. Each of the two pressing rollers has multiple forming grooves, and a rotating rod is fixedly connected to each of the two pressing rollers. A drive assembly is jointly provided on the extrusion chamber and the connecting box, which drives the two pressing rollers and the turnover groove to rotate.

[0006] Preferably, the drive assembly includes a mounting box fixedly connected to the connecting box and the side wall of the extrusion chamber. The ends of the two rotating rods away from the pressing roller are both disposed in the mounting box. A stepper motor is fixedly installed in the mounting box. The output end of the stepper motor is fixedly connected to one of the rotating rods. Gears are fixedly installed on both rotating rods, and the two gears are meshed together.

[0007] Preferably, the drive assembly further includes a transmission assembly, which includes a first transmission wheel, a second transmission wheel, and a transmission belt. The end of the rotating shaft facing away from the rotatable groove is disposed in the mounting box. The first transmission wheel is fixedly mounted on the rotating rod, the second transmission wheel is fixedly mounted on the rotating shaft, and the transmission belt is sleeved on the first and second transmission wheels.

[0008] Preferably, a material distribution screen plate is fixedly connected in the material distribution box, and a first discharge port and a second discharge port are opened on the lower end face of the material distribution box and the upper end face of the collection box. A first inclined block and a second inclined block are fixedly connected to the inner wall of the material distribution box, the first discharge port is located between the first inclined block and the second inclined block, and the second discharge port is located at the right end of the second inclined block.

[0009] Preferably, the material distribution box is equipped with a vibration assembly, which includes a geared motor fixedly installed on the side wall of the material distribution box. The output end of the geared motor passes through the side wall of the material distribution box and is fixedly connected to a rotating rod. Multiple connecting cylinders are fixedly connected at equal intervals on the rotating rod. A connecting rod is provided in the connecting cylinder. A striking head is fixedly connected to one end of the connecting rod away from the connecting cylinder. A spring is fixedly connected to the geared motor. The other end of the spring is fixedly connected to the inner wall of the connecting cylinder. A striking plate is fixedly connected to the lower end face of the material distribution screen plate.

[0010] Preferably, two discharge troughs are symmetrically fixedly connected to the side wall of the collection box, the left discharge trough corresponds to the first discharge port, and the right discharge trough corresponds to the second discharge port. A third inclined block is fixedly connected to the inner wall of the collection box.

[0011] Preferably, the upper end of the collection box is symmetrically and fixedly connected to two vertical plates, and the upper ends of the two vertical plates are fixedly connected to the discharge hopper.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a turnover trough driven by a drive component, the turnover trough can rotate continuously under the drive of a stepper motor, which uniformly and stably conveys the powder from the hopper to the two pressing rollers in the extrusion chamber. The dynamic feeding method completely avoids the problem of powder accumulation and blockage in the connecting box, and provides a guarantee for subsequent stable pressing.

[0013] 2. The material distribution box and vibration assembly are directly integrated after the pressing process. The pressed granules fall onto the material distribution screen plate. The vibration assembly, driven by a motor, continuously and frequently strikes the striking plate with a striking head, causing the material distribution screen plate to vibrate strongly. This vibration quickly separates qualified granules from unqualified powder and small particles. Qualified granules move along the screen plate and are discharged from the second discharge port, while unqualified materials pass through the screen holes and are discharged from the first discharge port. This achieves simultaneous production and sorting, eliminating the need for subsequent separate screening, greatly improving production efficiency, and ensuring that the final collected granule product has uniform size and high quality.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present utility model.

[0017] Please see Figures 1-5This embodiment provides a giant reed straw pellet press, including a hopper 1 and a collection box 5. A connecting box 2 is fixedly connected to the discharge port of the hopper 1. A distribution box 4 is fixedly connected to the upper end face of the collection box 5. An extrusion chamber 3 is fixedly connected between the connecting box 2 and the distribution box 4. A turnover groove 6 is rotatably arranged in the connecting box 2. A rotating shaft 61 is fixedly connected to the turnover groove 6. Two pressing rollers 7 are symmetrically rotatably arranged in the extrusion chamber 3. Multiple forming grooves are opened on both pressing rollers 7. A rotating rod 71 is fixedly connected to both pressing rollers 7. A driving assembly is jointly provided on the extrusion chamber 3 and the connecting box 2. The driving assembly drives the two pressing rollers 7 and the turnover groove 6 to rotate.

[0018] In summary, the improvement of this embodiment lies in: By setting up a turnover trough 6 driven by a drive component, the turnover trough 6 can rotate continuously under the drive of the drive component, and uniformly and stably convey the powder from the feed hopper 1 to the two pressing rollers 7 in the extrusion chamber. The dynamic feeding method completely avoids the problem of powder accumulation and blockage in the connecting box 2, and provides a guarantee for subsequent stable pressing.

[0019] Based on the above, other structures also need to be disclosed in detail, such as: The drive assembly includes a mounting box 81 fixedly connected to the side wall of the connecting box 2 and the extrusion chamber 3. Two rotating rods 71, each with one end facing away from the pressing roller 7, are both housed in the mounting box 81. A stepper motor 82 is fixedly mounted in the mounting box 81, and the output end of the stepper motor 82 is fixedly connected to one of the rotating rods 71. Gears 83 are fixedly mounted on both rotating rods 71, and the two gears 83 mesh with each other. The drive assembly also includes a transmission assembly 84, which includes a first transmission wheel 841, a second transmission wheel 842, and a transmission belt 843. The rotating shaft 61 faces away from the surrounding area. One end of the trough 6 is set in the mounting box 81. The first transmission wheel 841 is fixedly installed on the rotating rod 71, and the second transmission wheel 842 is fixedly installed on the rotating shaft 61. The transmission belt 843 is sleeved on the first transmission wheel 841 and the second transmission wheel 842. The stepper motor 82 is started and drives the two pressing rollers 7 to rotate relative to each other through the gear 83. At the same time, the transmission assembly 84 (the first transmission wheel 841, the transmission belt 843 and the second transmission wheel 842) drives the rotating shaft 61 to rotate, so that the trough 6 rotates. The rotation of the trough 6 feeds the raw material into the extrusion chamber 3 evenly and continuously.

[0020] A material distribution screen plate 41 is fixedly connected to the material distribution box 4. A first discharge port and a second discharge port are opened on the lower end face of the material distribution box 4 and the upper end face of the collection box 5. A first inclined block 42 and a second inclined block 43 are fixedly connected to the inner wall of the material distribution box 4. The first discharge port is located between the first inclined block 42 and the second inclined block 43, and the second discharge port is located at the right end of the second inclined block 43. A vibration assembly 44 is installed on the material distribution box 4. The vibration assembly 44 includes a reduction motor 44 fixedly installed on the side wall of the material distribution box 4. 1. The output end of the geared motor 441 passes through the side wall of the distribution box 4 and is fixedly connected to a rotating rod 442. Multiple connecting cylinders 443 are fixedly connected at equal intervals on the rotating rod 442. A connecting rod 444 is provided in the connecting cylinder 443. A striking head 445 is fixedly connected to one end of the connecting rod 444 away from the connecting cylinder 443. A spring 446 is fixedly connected to the geared motor 441. The other end of the spring 446 is fixedly connected to the inner wall of the connecting cylinder 443. A striking head 445 is fixedly connected to the lower end face of the distribution screen plate 41. There is a striking plate 411. Two discharge troughs 51 are symmetrically fixedly connected to the side wall of the collection box 5. The left discharge trough 51 corresponds to the first discharge port, and the right discharge trough (51) corresponds to the second discharge port. A third inclined block (52) is fixedly connected to the inner wall of the collection box (5). The particles fall into the distribution screen plate 41 of the distribution box 4. At the same time, the vibration component 44 works: the reduction motor 441 drives the rotating rod 442 to rotate, and the connecting cylinder 443 rotates with the rotating rod 442. The connecting rod 444 is in the spring 4 Under the action of elasticity and centrifugal force, the striking head 445 repeatedly strikes the striking plate 411, thereby causing the material distribution screen plate 41 to vibrate at a high frequency. The vibration causes the particles to disperse and screen on the material distribution screen plate 41. The particles (that do not meet the size requirements, i.e., powder) pass through the screen holes of the material distribution screen plate 41 and, guided by the first inclined block 42 and the second inclined block 43, fall into the collection box 5 through the first discharge port. The particles (that meet the size requirements) move down along the material distribution screen plate 41 and finally fall into the collection box 5 from the second discharge port.

[0021] The upper end of the collection box 5 is symmetrically and fixedly connected to two vertical plates 11. The upper ends of the two vertical plates 11 are fixedly connected to the discharge hopper 1. The vertical plates 11 provide structural support to ensure that the machine runs smoothly.

[0022] In summary, the working principle of this solution is as follows: Giant Napier grass straw powder falls from the hopper 1 into the turnover trough 6 of the connecting box 2. The stepper motor 82 starts and drives the two pressing rollers 7 to rotate relative to each other through the gear 83. At the same time, the transmission assembly 84 (first transmission wheel 841, transmission belt 843 and second transmission wheel 842) drives the rotating shaft 61 to rotate the turnover trough 6. The rotation of the turnover trough 6 feeds the raw material into the extrusion chamber 3 evenly and continuously, avoiding blockage and ensuring the stability of the feeding. After the powder enters the extrusion chamber 3, it is captured by the two relatively rotating pressing rollers 7. The forming grooves on the surface of the pressing rollers 7 press the powder into granules as they rotate. Due to the continuous rotation of the pressing rollers 7, the granules are continuously produced and fall into the distribution box 4 below by gravity. Particles fall onto the distribution screen plate 41 of the distribution box 4. Simultaneously, the vibration assembly 44 operates: the reduction motor 441 drives the rotating rod 442 to rotate, and the connecting cylinder 443 rotates with the rotating rod 442. Under the action of the spring force 446 and centrifugal force, the connecting rod 444 causes the striking head 445 to repeatedly strike the striking plate 411, thereby causing the distribution screen plate 41 to vibrate at a high frequency. This vibration disperses and screens the particles on the distribution screen plate 41. Particles (those that do not meet the size requirements, i.e., powder) pass through the sieve holes of the distribution screen plate 41 and are screened by the first inclined block 4. Guided by the second inclined block 43, the particles fall into the collection box 5 through the first discharge port. The particles (meeting the size requirements) move down along the distribution screen plate 41 and finally fall into the collection box 5 from the second discharge port. After entering the collection box 5, the particles flow to the corresponding discharge chute 51 under the guidance of the third inclined block 52. Qualified particles are output from the right discharge chute 51 and can be used for packaging or subsequent processing; unqualified particles are output from the left discharge chute 51 and can be returned for re-pressing. Throughout the process, the vertical plate 11 provides structural support to ensure the smooth operation of the machine.

[0023] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device (the specific model can be Siemens S7-1200), it belongs to existing mature technology, so its electrical connection relationship and specific circuit structure will not be described in detail here.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
