Description

Technical Field

[0001] This application relates to the field of agricultural production machinery technology, and in particular to a combined straw harvesting and weed removal device. Background Technology

[0002] Straw is a byproduct of agricultural production, mainly composed of the stalks and rachis of crops such as rice, corn, and wheat. These straws are produced after crop harvest and are produced in large quantities, but traditionally they have often been treated as waste.

[0003] Existing straw harvesting equipment typically uses a harvesting mechanism consisting of several cutting blades, a rotating shaft, and a first motor to collect straw from the field. However, during the harvesting process, the straw may carry soil along with it into the device, which can affect the efficiency of the collection work.

[0004] Therefore, this utility model proposes a combined equipment for straw harvesting and weed removal. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a combined straw harvesting and weed removal device, which solves the problem that during the harvesting process, straw may carry soil along with it and be collected into the device, thus affecting the efficiency of the collection work.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: a combined straw harvesting and weeding device, comprising a vehicle body, a harvesting mechanism, a screening mechanism, and a collecting mechanism. The harvesting mechanism is fixedly installed at the front end of the vehicle body, the collecting mechanism is fixedly installed at the rear end of the vehicle body, and the screening mechanism is fixedly installed inside the vehicle body and located between the harvesting mechanism and the collecting mechanism. The screening mechanism includes a first motor, a rotating shaft, a cam, and a screen plate. The first motor is fixedly installed on one side of the vehicle body, and the output end of the first motor passes through one side of the vehicle body and is fixedly connected to one end of the rotating shaft. The other end of the rotating shaft is rotatably connected to one side of the vehicle body. The cam is fixedly installed on the rotating shaft, and the end point of the cam abuts against the bottom surface of the screen plate. The screen plate is placed inside the vehicle body, and a spring is fixedly connected to the bottom surface of the screen plate. The other end of the spring is fixedly connected to the bottom surface of the vehicle body.

[0007] Furthermore, a cylinder is fixedly installed on the top surface of the vehicle body, and a pressure plate is fixedly installed on the output end of the cylinder, with the pressure plate located directly above the sieve plate.

[0008] Furthermore, four springs are provided and arranged in a rectangular array on the bottom surface of the sieve plate.

[0009] Furthermore, a mud and sand collection box is placed at the bottom of the vehicle body, and the mud and sand collection box is located directly below the sieve plate.

[0010] Furthermore, the collection mechanism includes a crushing chamber fixedly installed inside the vehicle body and a second motor fixedly installed on the side wall of the crushing chamber. A roller blade is fixedly installed at the output end of the second motor, and the crushing chamber is located below the far end of the sieve plate.

[0011] Furthermore, there are two of each of the second motor and the roller cutter, which are parallel and symmetrical to the side wall inside the crushing chamber.

[0012] Furthermore, the bottom of the pulverizing chamber is hollowed out, and the collecting mechanism also includes a collecting chamber, which is placed on the bottom surface of the vehicle body and located directly below the pulverizing chamber.

[0013] Furthermore, the harvesting mechanism includes a third motor fixedly mounted on one side of the vehicle body and a roller plow blade fixedly mounted on the third motor.

[0014] Furthermore, the harvesting mechanism also includes a fixed frame fixedly installed at the front end of the vehicle body, and a cutting blade is fixedly installed between opposite sides of the fixed frame, with the cutting blade located on the side of the roller plow blade away from the vehicle body.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] When using the device, the harvesting mechanism cuts straw from the land into the device. However, the harvested straw carries some soil with it. When the harvested straw falls onto the screen plate, the first motor is activated, which drives the rotating shaft to rotate. The rotation of the rotating shaft causes the cam to rotate. When one end of the cam contacts the bottom surface of the screen plate, the cam lifts the screen plate. As the rotating shaft rotates, the cam moves away from the bottom surface of the screen plate, and the screen plate descends until the cam contacts the screen plate again, lifting it up once more. The use of the first motor allows the screen plate to continuously vibrate up and down, thereby separating the straw from the mixed soil for subsequent collection, effectively improving the working efficiency of the device.

[0017] When the harvested straw falls onto the top surface of the sieve plate, the cylinder is activated, and the extension and retraction of the cylinder presses the pressure plate downward, causing the pressure plate to squeeze the straw on the top surface of the sieve plate. This loosens the soil on the straw, allowing it to be better separated by the shaking of the sieve plate, effectively improving the working efficiency of the device. Attached Figure Description

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] Example, refer to Figures 1-3 A combined straw harvesting and weeding device includes a vehicle body 1, a harvesting mechanism 2, a screening mechanism 3, and a collecting mechanism 4. The harvesting mechanism 2 is fixedly installed at the front end of the vehicle body 1, the collecting mechanism 4 is fixedly installed at the rear end of the vehicle body 1, and the screening mechanism 3 is fixedly installed inside the vehicle body 1, located between the harvesting mechanism 2 and the collecting mechanism 4. The screening mechanism 3 includes a first motor 31, a rotating shaft 32, a cam 33, and a screen plate 34. The first motor 31 is fixedly installed on one side of the vehicle body 1, and its output end passes through one side of the vehicle body 1 and is fixedly connected to one end of the rotating shaft 32. The other end of the rotating shaft 32 is rotatably connected to one side inside the vehicle body 1. The cam 33 is fixedly installed on the rotating shaft 32, and the end of the cam 33 abuts against the bottom surface of the screen plate 34, which is placed inside the vehicle body 1. A spring 35 is fixedly connected to the bottom surface of the screen plate 34, and the other end of the spring 35 is fixedly connected to the bottom surface inside the vehicle body 1. Four springs 35 are arranged in a rectangular array on the bottom surface of the screen plate 34. When using the device, the harvesting mechanism 2 harvests straw from the land into the device. However, the harvested straw carries some soil into the device. When the harvested straw falls onto the surface of the sieve plate 34, the first motor 31 is started. The first motor 31 drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 causes the cam 33 to rotate. When one end of the cam 33 rotates and touches the bottom surface of the sieve plate 34, the cam 33 lifts the sieve plate 34. As the rotating shaft 32 rotates, when one end of the cam 33 moves away from the bottom surface of the sieve plate 34, the sieve plate 34 descends until the cam 33 touches the sieve plate 34 again, lifting the sieve plate 34 again. The use of the first motor 31 enables the sieve plate 34 to continuously vibrate up and down. The spring 35 accelerates the up and down vibration of the sieve plate 34, thereby separating the straw from the mixed soil for subsequent collection work, effectively improving the working efficiency of the device.

[0024] Reference Figure 2A cylinder 11 is fixedly installed on the top surface inside the vehicle body 1, and a pressure plate 12 is fixedly installed on the output end of the cylinder 11. The pressure plate 12 is located directly above the screen plate 34. When the harvested straw falls onto the top surface of the screen plate 34, the cylinder 11 is activated. The extension and retraction of the cylinder 11 presses the pressure plate 12 downward, causing the pressure plate 12 to squeeze the straw on the top surface of the screen plate 34. This loosens the soil on the straw, allowing it to be better separated by the shaking of the screen plate 34, effectively improving the working efficiency of the device.

[0025] Reference Figure 1 A sediment collection box 13 is placed at the bottom of the vehicle body 1, directly below the sieve plate 34. After separating straw from soil, the sediment can be collected through the sediment collection box 13 for subsequent processing, effectively improving the practicality of the device.

[0026] Reference Figure 1 The collection mechanism 4 includes a crushing chamber 41 fixedly installed inside the vehicle body 1 and a second motor 42 fixedly installed on the side wall of the crushing chamber 41. A roller cutter 43 is fixedly installed at the output end of the second motor 42. The crushing chamber 41 is located below the far end of the sieve plate 34. Two second motors 42 and two roller cutters 43 are provided, each parallel and symmetrical to the side wall inside the crushing chamber 41. When using the device, by starting the second motor 42, the second motor 42 drives the roller cutter 43 to rotate, which crushes the collected straw, effectively improving the recycling efficiency of the device.

[0027] Reference Figure 1 The bottom of the crushing chamber 41 is hollowed out. The collecting mechanism 4 also includes a collecting chamber 44, which is placed on the bottom surface of the vehicle body 1 and located directly below the crushing chamber 41. After the straw is crushed, the crushed straw is collected in the collecting chamber 44.

[0028] Reference Figure 1 as well as Figure 3 The harvesting mechanism 2 includes a third motor 21 fixedly mounted on one side of the vehicle body 1 and a roller plow blade 22 fixedly mounted on the third motor 21. The harvesting mechanism 2 also includes a fixed frame 23 fixedly mounted on the front end of the vehicle body 1. A cutting blade 24 is fixedly mounted between opposite sides of the fixed frame 23, located on the side of the roller plow blade 22 away from the vehicle body 1. When using the device, the cutting blade 24 cuts the straw on the soil surface. Then, by starting the third motor 21, the third motor 21 drives the roller plow blade 22 to rotate. The rotation of the roller plow blade 22 lifts the roots of the straw from the soil. Through rotation, the straw is tumbled into the device, effectively improving the device's working efficiency.

[0029] Working principle:

[0030] When using the device, the cutting blade 24 cuts the straw on the soil surface. Then, by starting the third motor 21, the third motor 21 drives the roller plow blade 22 to rotate. The rotation of the roller plow blade 22 lifts the roots of the straw from the soil. Through rotation, the straw is rolled into the device. Then, by starting the cylinder 11, the extension and retraction of the cylinder 11 presses the pressure plate 12 downward, causing the pressure plate 12 to squeeze the straw on the top surface of the screen plate 34, thereby loosening the soil on the straw. Finally, by starting the first motor 31, the first motor 31 drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 causes the cam 33 to rotate. When one end of the cam 33 rotates and touches the bottom surface of the screen plate 34, the cam 33 lifts the screen plate 34. As the rotating shaft 32 rotates, when one end of the cam 33 moves away from the bottom surface of the screen plate 34, the screen plate 34 descends until the cam 33 touches the screen plate 34 again, at which point it can lift the screen plate 34 again. The use of the first motor 31 enables the screen plate 34 to continuously vibrate up and down. Through the spring 35, the straw is separated from the mixed soil, effectively improving the working efficiency of the device.

[0031] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
