[0024] 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, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 The present invention provides the following technical solution:
[0026] A corn stalk pellet mill includes a base plate 1, a cooling box 2 is bolted to the left side of the top of the base plate 1, a pellet mill body 3 is set on the top of the cooling box 2, a protective cover 4 is bolted to the top of the base plate 1, a multi-stage crushing mechanism 5 is set on the top of the base plate 1, a collecting hopper 6 is set on the top of the pellet mill body 3, and a self-draining component 7 is set inside the collecting hopper 6.
[0027] The self-dredging component 7 includes a first high-pressure jet nozzle 71 and a second high-pressure jet nozzle 72. The first high-pressure jet nozzle 71 is located on the front side inside the collection hopper 6, and the second high-pressure jet nozzle 72 is located on the rear side inside the collection hopper 6. A pressure sensor 73 is bolted to the inner wall inside the collection hopper 6, and a controller 74 is bolted to the top of the protective cover 4.
[0028] In this embodiment: the entire equipment uses the base plate 1 as its basic support structure. The operator first prepares the corn stalk raw material and turns on the power. At this time, the power motor 14 starts running, providing power support for the subsequent operation of the pellet mill body 3. The cooling box 2 starts operating to cool the pellet mill body 3 located on top of it, preventing damage due to overheating during prolonged operation and ensuring stable performance. The multi-stage crushing mechanism 5 starts, preparing to crush the corn stalks. Simultaneously, the protective cover 4 plays its protective role, preventing operators from accidentally contacting the internal moving parts and ensuring operational safety. As the multi-stage crushing mechanism 5 crushes the corn stalks... Material enters the collection hopper 6 through the discharge port 54. The pressure sensor 73 inside the collection hopper 6 monitors the internal pressure in real time. If a blockage occurs, the pressure change signal will be transmitted to the controller 74 on the top of the protective cover 4, which will trigger the self-unblocking component 7 to work, ensuring that the material can smoothly enter the pellet mill body 3 for forming. When the pressure sensor 73 detects an abnormal increase in pressure inside the collection hopper 6, it means that there may be a blockage. The pressure sensor 73 transmits this signal to the controller 74 on the top of the protective cover 4, which will cause the first high-pressure jet nozzle 71 and the second high-pressure jet nozzle 72 to spray air into the collection hopper 6 to clear the blockage and ensure that the material can be smoothly conveyed to the pellet mill body 3.
[0029] Specifically, such as Figure 1 , Figure 2 As shown, the multi-stage crushing mechanism 5 includes four support columns 51, the bottom of which is bolted to the top of the base plate 1, and a crushing box 52 is bolted between the tops of the four support columns 51.
[0030] Specifically, such as Figure 2 As shown, a feed inlet 53 is provided on the right side of the crushing box 52, and a discharge outlet 54 is provided on the left side of the crushing box 52. The left side of the discharge outlet 54 is fixedly connected to the right side of the collecting hopper 6.
[0031] Specifically, such as Figure 2 As shown, the first shredder assembly 55, the second shredder assembly 56, and the third shredder assembly 57 are rotatably connected inside the shredder box 52.
[0032] In this embodiment: the four support columns 51 of the multi-stage crushing mechanism 5 securely mount the crushing box 52 on the top of the base plate 1, ensuring the stability of the crushing process. The operator puts corn stalks into the crushing box 52 through the feed port 53 on the right side of the crushing box 52. The first crushing blade group 55, the second crushing blade group 56, and the third crushing blade group 57 inside the crushing box 52 start to rotate at high speed under the drive of the power motor 14. The first crushing blade group 55 first performs preliminary crushing on the corn stalks, cutting and breaking up the larger stalk pieces. Then, the material continues to move in the crushing box 52. The second crushing blade group 56 further refines the material, making the particle size of the straw further decrease. Finally, the third crushing blade group 57 performs fine crushing on the material, crushing the straw into a particle size suitable for pelleting. After these three stages of crushing, the crushed material that meets the requirements is discharged from the discharge port 54 on the left side of the crushing box 52 and enters the collection hopper 6 on the right side through the collection hopper 6 which is fixedly connected to the discharge port 54.
[0033] Specifically, such as Figure 4 , Figure 3 As shown, a high-pressure air pump 8 is provided on the top of the protective cover 4, and a first air delivery channel 9 and a second air delivery channel 10 are provided on the left side of the high-pressure air pump 8.
[0034] Specifically, such as Figure 3 As shown, a first air supply pipe 11 is fixedly connected between the left side of the first air supply channel 9 and the front side of the first high-pressure jet nozzle 71, and a second air supply pipe 12 is fixedly connected between the left side of the second air supply channel 10 and the rear side of the second high-pressure jet nozzle 72.
[0035] In this embodiment: When the equipment is running, the high-pressure air pump 8 on top of the protective cover 4 is in standby mode. The pressure sensor 73 inside the collecting hopper 6 continuously monitors the internal pressure. When material causes blockage in the collecting hopper 6, the pressure inside the collecting hopper 6 will rise rapidly. After detecting the pressure abnormality, the pressure sensor 73 transmits a signal to the controller 74 on top of the protective cover 4. Upon receiving the signal, the controller 74 immediately controls the high-pressure air pump 8 to start. The high-pressure air pump 8 begins to work, generating high-pressure gas. The high-pressure gas is delivered through the first air delivery channel 9 and the second air delivery channel 10, respectively. The high-pressure gas in the channel 9 is delivered to the first high-pressure jet nozzle 71 at the front of the collection hopper 6 through the first air delivery pipe 11, which is fixedly connected to the front side of the first high-pressure jet nozzle 71; the high-pressure gas in the second air delivery channel 10 is delivered to the second high-pressure jet nozzle 72 at the rear side of the collection hopper 6 through the second air delivery pipe 12, which is fixedly connected to the rear side of the second high-pressure jet nozzle 72. The first high-pressure jet nozzle 71 and the second high-pressure jet nozzle 72 simultaneously spray gas into the collection hopper 6. The powerful airflow disperses the blocked material, thereby clearing the collection hopper 6 and ensuring that the material can be smoothly conveyed to the pellet mill body 3.
[0036] Specifically, such as Figure 4 As shown, a connecting shaft 13 is provided at the bottom right side of the pellet mill body 3. The connecting shaft 13 extends into the protective cover 4. A power motor 14 is bolted to the top of the base plate 1. The output shaft of the power motor 14 extends into the protective cover 4 and is bolted to the connecting shaft 13.
[0037] Specifically, such as Figure 1 , Figure 5 As shown, pins 15 are bolted to both the front and rear sides of the base plate 1, and a rotating wheel 16 is fitted on the surface of the pin 15.
[0038] In this embodiment: the power motor 14 is installed on the top of the base plate 1. When the equipment is started, the output shaft of the power motor 14 starts to rotate. The output shaft of the power motor 14 extends into the protective cover 4 and is bolted to the connecting shaft 13 extending into the protective cover 4 from the bottom right side of the pellet mill body 3. As the output shaft of the power motor 14 rotates, the power is transmitted to the pellet mill body 3 through the connecting shaft 13, so that the pellet mill body 3 starts to work and performs molding operations on the incoming crushed material, making it into pellets. When the equipment needs to be moved, the operator can push the corn stalk pellet mill. Since the front and rear sides of the base plate 1 are equipped with rotating wheels 16 through pins 15, the rotating wheels 16 can rotate flexibly around the pins 15, so that the entire equipment can be easily moved to the designated working position, making it convenient for the equipment to operate in different locations.
[0039] Working Principle: The corn stalk pellet mill uses a base plate 1 as its basic support structure. Wheels 16 are mounted on both the front and rear sides of the base plate 1 via pins 15, facilitating movement of the equipment to the designated working position. After the operator prepares the corn stalk raw material, they turn on the power, and the motor 14 starts running. Its output shaft extends into the protective cover 4 and is bolted to the connecting shaft 13 extending into the protective cover 4 on the bottom right side of the pellet mill body 3, providing power for the pellet mill body 3. Simultaneously, the cooling box 2 starts operating, cooling the pellet mill body 3 located on top of it to ensure stable performance. The multi-stage crushing mechanism 5 is activated, and four support columns 51 securely mount the crushing box 52 on top of the base plate 1. The operator feeds the corn stalks into the crushing box 52 through the feed inlet 53 on the right side. The first crushing blade group 55, the second crushing blade group 56, and the third crushing blade group 57 inside the box rotate at high speed driven by the motor 14, sequentially performing preliminary, fine, and high-precision crushing of the corn stalks. The straw is crushed into a suitable particle size for pelleting. The crushed material is discharged from the discharge port 54 on the left side of the crushing box 52 and enters the collection hopper 6 on the right side through the collection hopper 6 which is fixedly connected to the discharge port 54. The pressure sensor 73 inside the collection hopper 6 continuously monitors the internal pressure. If the material is blocked in the collection hopper 6, the pressure will rise rapidly. After the pressure sensor 73 detects the abnormality, it transmits the signal to the controller 74 on the top of the protective cover 4. The controller 74 immediately controls the high-pressure air pump 8, which is in standby mode, to start. The high-pressure gas generated by the high-pressure air pump 8 is delivered through the first air delivery channel 9 and the second air delivery channel 10, respectively. It reaches the first high-pressure jet nozzle 71 on the front side and the second high-pressure jet nozzle 72 on the rear side inside the collection hopper 6 through the first air delivery pipe 11 and the second air delivery pipe 12, respectively. Both of them spray air into the collection hopper 6 at the same time to disperse the blocked material and ensure that the material is smoothly delivered to the pellet mill body 3. Finally, the pellet mill body 3 performs a molding operation on the incoming crushed material and makes it into pellets.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
