Abstract
Description
Technical Field
[0001] This utility model belongs to the field of straw crushing technology, and in particular relates to a straw crushing and returning equipment for agricultural planting. Background Technology
[0002] Straw, also known as straw or rice straw, refers to the stems and leaves remaining after rice, wheat, corn and other grass crops have matured and been threshed. Rice straw is often called rice straw or rice stalk, while wheat straw is called wheat straw.
[0003] In modern agricultural production, to avoid environmental pollution from burning straw, straw crushing equipment is often used to crush the straw and return it to the farmland. During the straw crushing and returning process, the friction and collision between the high-speed rotating blades and the straw will generate a large amount of dust. However, existing straw crushing equipment does not have a dust removal function, which leads to pollution of the field air during straw crushing and endangers the respiratory health of operators. Utility Model Content
[0004] The purpose of this invention is to provide a straw crushing and returning equipment for agricultural planting. By setting up a dust removal chamber, specifically by starting a fan, air containing dust is drawn into the dust removal chamber through the air inlet and air inlet pipe. The screen plate can prevent straw from being sucked in. At this time, the air containing dust is filtered by the dust removal bag and discharged through the exhaust port. Larger particles are intercepted by the dust removal bag and fall into the crushing chamber from the material outlet. This solves the problem that existing straw crushing equipment does not have a dust removal function, which leads to pollution of the field air during straw crushing and endangers the respiratory health of operators.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a straw crushing and returning equipment for agricultural planting, comprising a feeding bin and a crushing bin. A dust removal bin is fixedly connected to the top of the feeding bin and the crushing bin. An air inlet is provided in front of the dust removal bin, and a screen plate is fixedly connected to the bottom of the air inlet. The bottom of the screen plate is fixedly connected to the top of the feeding bin. Three air inlet pipes are fixedly connected to the top of the air inlet, and the back of the air inlet pipes is fixedly connected to the front of the dust removal bin. A material discharge port is provided at the bottom of the dust removal bin. A dust removal bag is provided near the rear of the material discharge port in the dust removal bin. Two fans are fixedly connected inside the dust removal bin near the rear of the dust removal bag. An exhaust port is fixedly connected to the back of the dust removal bin. The dust generated by the equipment is filtered by the dust removal bin and then discharged, which can largely avoid the harm of dust and protect the environment and the health and safety of the operators.
[0007] Furthermore, the top and bottom of the dust collection chamber are fixedly connected to slide rails, and sliders are slidably connected inside the slide rails. The corresponding sides of the two sliders are fixedly connected to the dust collection bags. A chamber door is provided on the right side of the dust collection chamber, and the left side of the chamber door contacts the right side of the sliders. The dust collection bags are designed to be detachable so that they can be replaced or cleaned in a timely manner, avoiding dust accumulation and improving dust collection efficiency.
[0008] Furthermore, a breaking shaft is rotatably connected to the inner wall of the feeding hopper, and a spiral feeding shaft is rotatably connected to the inner wall of the feeding hopper near the rear of the breaking shaft. A feeding blade is fixedly connected to the center of the spiral feeding shaft, and the spiral blades of the spiral feeding shaft are arranged in two opposite directions. Two guide plates are fixedly connected to the inner wall of the feeding hopper near the rear of the spiral feeding shaft. The cooperative design of the breaking shaft and the spiral feeding shaft can effectively prevent straw from tangling or clogging during the feeding process. The bidirectional spiral blades and guide plates ensure uniform straw conveying, reduce feeding resistance, and improve feeding efficiency.
[0009] Furthermore, a motor is fixedly connected inside the guide plate located on the right side. A pulley assembly is provided on the left and right sides of the feed hopper. The left and right sides of the spiral feeding shaft are fixedly connected to the driven pulley in the pulley assembly. The left side of the breaking shaft is fixedly connected to the driven pulley in the pulley assembly. The right output end of the motor is fixedly connected to the transmission pulley in the pulley assembly. The motor drives the breaking shaft and the spiral feeding shaft to operate synchronously through the pulley assembly, ensuring the continuity and stability of the feeding process, while simplifying the transmission structure and reducing the equipment manufacturing cost and maintenance difficulty.
[0010] Furthermore, a crushing chamber is fixedly connected to the rear of the feeding chamber, and a crushing shaft is rotatably connected to the inner wall of the crushing chamber. A second guide plate is fixedly connected to the inner wall of the crushing chamber near the lower part of the crushing shaft. The direct connection design between the crushing chamber and the feeding chamber shortens the straw conveying path and reduces energy loss. The cooperation between the crushing shaft and the second guide plate can improve the straw crushing efficiency.
[0011] Furthermore, two crushing plates are fixedly connected to the inner wall of the crushing chamber near the back of the guide plate, and two feeding shafts are rotatably connected to the inner wall of the crushing chamber near the bottom of the crushing plates. The combination design of the crushing plates and the feeding shafts can further refine the straw fragments, ensuring that the crushed material meets the requirements for returning to the field. At the same time, the feeding shafts will evenly transport the crushed straw to the discharge port to avoid material accumulation.
[0012] Furthermore, a second set of pulleys is provided on the left side of the crushing chamber. The left side of the crushing shaft and the crushing plate are both fixedly connected to the driven wheel in the second set of pulleys. A second motor is fixedly connected inside the first guide plate on the left side. The left output end of the second motor is fixedly connected to the transmission wheel in the second set of pulleys. The second motor drives the crushing shaft and the crushing plate to operate synchronously through the second set of pulleys, ensuring the continuity and efficiency of the crushing process, while simplifying the power transmission structure and reducing the energy consumption of the equipment.
[0013] This utility model has the following beneficial effects:
[0014] 1. This utility model incorporates a dust collection chamber. Specifically, by starting a fan, air containing dust is drawn into the dust collection chamber through the air inlet and air inlet pipe. The sieve plate prevents straw from being sucked in. The air containing dust is then filtered by the dust collection bag and discharged through the exhaust port. Larger particles are intercepted by the dust collection bag and fall into the crushing chamber from the material discharge port. This can largely avoid the harm of dust and protect the environment and the health and safety of operators.
[0015] 2. This utility model incorporates a dust collector bag. Specifically, after the straw crushing and returning to the field is completed, the hopper door is opened, and the slider is pulled to slide along the inner wall of the slide rail, thereby removing the dust collector bag for cleaning or replacement. After the hopper door is closed, the left side of the hopper door contacts the right side of the slider to limit its movement, preventing the dust collector bag from shifting during operation. The detachable design of the dust collector bag allows for timely replacement or cleaning, preventing dust accumulation and improving dust removal efficiency.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
