Abstract
Description
Technical Field
[0001] This utility model relates to the field of crusher technology, and in particular to a corn stalk crusher. Background Technology
[0002] Corn stalks refer to the portion of corn plant matter left in the field after the corn matures and is harvested. To address the problems associated with their original state and fully utilize their potential value, it is usually necessary to crush the whole stalks or longer ones. This not only accelerates decomposition and returns the stalks to the field, enriching the soil, but also facilitates collection, transportation, and subsequent processing. However, current crushing equipment generally cuts corn stalks directly with blades. Corn stalks have a certain degree of toughness and nodules, which may lead to incomplete cutting during the process. This results in inadequate crushing of the corn stalks, affecting their subsequent use and reducing the practicality of the equipment. Furthermore, the crushed corn stalks often have multiple uses depending on the particle size, but most current equipment does not screen them, potentially leading to low utilization rates and waste, further reducing the equipment's practicality. Therefore, it is necessary to provide a new type of corn stalk crusher to solve the above-mentioned technical problems. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a corn stalk crusher.
[0004] The present invention is achieved by the following technical solution: a corn stalk crusher, comprising: a box body and a feed inlet fixedly connected to the outer surface of the upper end of the box body, a guide belt is installed at the upper end of the box body, a crushing structure is provided at the middle position of the box body, and a filter structure is provided at the lower end of the box body. The crushing structure includes hydraulic rods, limiting rods, pressure plates, support rods, rotating rods, a motor, a transmission belt, and rotating blades. Two sets of hydraulic rods are installed on the inner wall surfaces at both ends of the housing. Four sets of limiting rods are fixedly connected to the inner wall surfaces at both ends of the housing, on either side of the two sets of hydraulic rods. Two sets of pressure plates are fixedly connected to the outer surfaces of the two sets of hydraulic rods and limiting rods, respectively, at their respective closest points. The support rods are fixedly connected to the inner wall surfaces on both sides of the housing. The rotating rod is engaged with the inner surface of the outer surface at the middle position of the support rod. The motor is installed on the outer surface of one end of the housing. The transmission belt is sleeved on the outer surface of the rotating rod and connected to the output end of the motor. The rotating blades are fixedly connected to the outer surface of the lower end of the rotating rod. The filtration structure includes a filter plate, a first electric telescopic rod, a connecting groove, a collection box, a connecting plate, a second electric telescopic rod, and a collection groove. The filter plate is hinged to the inner wall surface of the housing. The first electric telescopic rod is installed on the inner wall surface of one end of the housing. The connecting groove is opened inside the inner wall surface of the other end of the housing. The collection box is engaged with the outer surface of the lower end of the other end of the housing. The connecting plate is hinged to the inner wall surface of the housing. The second electric telescopic rod is installed on the inner wall surface of the other end of the housing. The collection groove is fixedly connected to the outer surface of the lower end of one end of the housing.
[0005] As a further embodiment of this utility model, the two sets of guide belts are inclined, and the ends of the two sets of guide belts that are close to each other rotate downwards.
[0006] As a further embodiment of this utility model, the outer surfaces of both sides of the pressure plate are in contact with the inner wall surfaces of both sides of the box.
[0007] As a further embodiment of this utility model, the support rod has a rotating groove inside, the outer surface of the rotating rod has a rotating ring, and the inner size of the rotating groove is adapted to the outer size of the rotating ring. The outer surface of the rotating rod and the output end of the motor are provided with a limiting ring, and the inner wall surface of the limiting ring is in contact with the outer surface of the transmission belt.
[0008] As a further embodiment of this utility model, the outer surface of the upper end of the first electric telescopic rod abuts against the bottom surface of one end of the filter plate, and the lower end of the filter plate corresponds to the position of the connecting groove.
[0009] As a further embodiment of this utility model, the outer surface of the upper end of the second electric telescopic rod abuts against the bottom surface of one end of the connecting plate, and the lower end of the connecting plate corresponds to the position of the collecting groove.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By feeding corn stalks into the inlet and continuously guiding them into the box via a rotating guide belt, two sets of hydraulic rods are activated, causing the two sets of pressure plates to continuously move closer and further apart, thus squeezing the corn stalks inside the box. This crushes the fibers and nodules inside the corn stalks. The motor is then started, driving the rotating rod to rotate inside the support rod, which in turn drives the rotating blades to rotate at high speed, cutting the corn stalks inside the box. This makes it easier to crush the corn stalks more completely, thus improving the practicality of the equipment to a certain extent. 2. By activating the first electric telescopic rod, the upper end of the first electric telescopic rod moves up and down alternately, causing the filter plate to vibrate continuously. This allows the crushed corn stalks to be screened more quickly on the upper part of the filter plate. Larger stalk fragments will slide off the upper part of the filter plate under the vibration and fall into the collection box through the connecting groove. Smaller stalk fragments will fall directly from the gaps in the filter plate onto the outer surface of the upper part of the connecting plate. At the same time, activating the second electric telescopic rod will similarly cause the connecting plate to vibrate continuously, which will accelerate the sliding of stalk fragments from the outer surface of the upper part of the connecting plate into the collection groove, facilitating subsequent collection and processing. This allows for different classification and processing of stalk fragments according to their size, facilitating different uses and greatly improving utilization rate, thus enhancing the practicality of the equipment to a certain extent.

The rotating blades 48 are fixedly connected to the outer surface of the lower end of the rotating rods 45. The filter structure 5 includes a filter plate 51, a first electric telescopic rod 52, a connecting groove 53, a collection box 54, a connecting plate 55, a second electric telescopic rod 56, and a collection groove 57. The filter plate 51 is hinged to the inner wall surface of the box body 1. The first electric telescopic rod 52 is installed on the inner wall surface of one end of the box body 1. The connecting groove 53 is opened inside the inner wall surface of the other end of the box body 1. The collection box 54 is engaged with the outer surface of the lower end of the other end of the box body 1. The connecting plate 55 is hinged to the inner wall surface of the box body 1. The second electric telescopic rod 56 is installed on the inner wall surface of the other end of the box body 1. The collection groove 57 is fixedly connected to the outer surface of the lower end of one end of the box body 1.
[0015] The two sets of guide belts 3 are inclined, and the ends of the two sets of guide belts 3 that are close to each other rotate downwards.
[0016] The outer surfaces of the pressure plate 43 on both sides are in contact with the inner wall surfaces of the box body 1 on both sides.
[0017] The support rod 44 has a rotating groove inside, and the outer surface of the rotating rod 45 has a rotating ring. The inner dimensions of the rotating groove are adapted to the outer dimensions of the rotating ring. The outer surface of the rotating rod 45 and the output end of the motor 46 have a limiting ring, and the inner wall surface of the limiting ring is in contact with the outer surface of the transmission belt 47.
[0018] The outer surface of the upper end of the first electric telescopic rod 52 abuts against the bottom surface of one end of the filter plate 51, and the lower end of the filter plate 51 corresponds to the position of the connecting groove 53.
[0019] The outer surface of the upper end of the second electric telescopic rod 56 abuts against the bottom surface of one end of the connecting plate 55, and the lower end of the connecting plate 55 corresponds to the position of the collecting groove 57.
[0020] The working principle of the corn stalk crusher provided by this utility model is as follows: First step: First, corn stalks are fed into the inlet 2, and the guide belt 3 is started. The rotation of the two sets of guide belts 3 can drive the corn stalks inside the inlet 2 to continuously enter the box 1. At the same time, the two sets of hydraulic rods 41 are started, which drive the two sets of pressure plates 43 to move closer and further away from each other. The pressure plates 43 are more stable when moving inside the box 1. The two sets of pressure plates 43 crush the fibers and knots of the corn stalks, making the corn stalks easier to cut. Then, the motor 46 is started, and the transmission belt 47 drives the rotating rod 45 to rotate. The transmission belt 47 is more stable when driving, and the rotating rod 45 is more stable when rotating inside the support rod 44. This drives the rotating blade 48 to rotate and cut and crush the corn stalks. This makes the corn stalks crushed more thoroughly and avoids the situation where the corn stalks are not crushed in some places, which improves the practicality of the equipment to a certain extent. The second step: After the crushed straw fragments fall onto the outer surface of the upper end of the filter plate 51, the first electric telescopic rod 52 is activated, causing the upper end of the first electric telescopic rod 52 to move up and down continuously, thereby driving the filter plate 51 to vibrate continuously. This accelerates the screening of the straw fragments on the upper end of the filter plate 51. Larger straw fragments will slide from the upper end of the filter plate 51 to the position of the connecting groove 53, and then enter the interior of the collection box 54 through the connecting groove 53 for collection. Smaller straw fragments will fall directly from the gaps in the filter plate 51 onto the outer surface of the upper end of the connecting plate 55, and then slide from the upper end of the connecting plate 55 into the interior of the collection groove 57 for collection. Simultaneously, the second electric telescopic rod 56 is activated, which, like the first electric telescopic rod 52, causes the connecting plate 55 to vibrate, thereby accelerating the speed at which the straw fragments slide into the interior of the collection groove 57. This facilitates different classification and processing of straw fragments according to their size, making it easier for different uses and greatly improving utilization.
