Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a crop straw pulling device. Background Technology

[0002] In crop cultivation, after the crops mature and the seeds are harvested, straw remains on the planted ground. Straw is a multi-purpose renewable biomass, such as fertilizer, roughage, and building material. Therefore, to improve efficiency when pulling out straw, straw pulling devices are usually used to replace manual straw pulling, thereby achieving efficient straw pulling and facilitating straw recycling.

[0003] A Chinese patent with authorization announcement number CN221043782U discloses a crop straw pulling device. This device moves a positioning frame to position the straw between two strip frames. During the movement of the positioning frame, the straw moves between the two strip frames, and a second motor drives the conveying wheel to rotate through a transmission rod. Due to the force generated by the spring, the conveying wheel between the two strip frames presses against each other, pressing the surface of the straw against each other, and then moves backward to pull the straw until it is pulled out of the ground. The pulled-out straw is then crushed by a crushing roller and enters a collection frame, which greatly improves the straw pulling efficiency. However, when pulling straw from the ground, the roots of the straw often carry soil. The aforementioned pulling device cannot knock off the soil from the roots of the straw, causing the soil to enter the crushing structure along with the straw. This not only affects the crushing process of the straw, but also results in soil mixed in with the crushed straw, making it difficult to utilize the straw later, and thus hindering the use of the pulling device. Utility Model Content

[0004] The purpose of this invention is to provide a crop straw pulling device to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crop straw pulling device, including a movable frame, a crushing mechanism, a pulling mechanism, and a collection box arranged on the frame, wherein the collection box is located directly below the crushing mechanism, and also includes a soil-beating mechanism for beating the roots of the straw.

[0006] The soil-beating mechanism includes two symmetrically distributed and relatively movable soil-beating rods. Springs are connected between the opposite sides of the two soil-beating rods and the inner wall of the frame. The frame is also equipped with a power component that drives the two soil-beating rods to move relative to each other.

[0007] Preferably, the power component includes mounting seats fixed on both sides of the inner wall of the frame and transmission rods installed on opposite sides of the two soil-tamping rods. Each of the two mounting seats is equipped with a motor, and each of the two motors has a sector gear on its main shaft. Each of the two transmission rods has a toothed protrusion that meshes with the sector gear on one side. The frame has through holes through which the two transmission rods pass.

[0008] Preferably, a limiting slider is also installed on the inner wall of the through hole, and a limiting groove is provided on the side of the transmission rod away from the protruding tooth for the limiting slider to slide.

[0009] Preferably, the frame is further provided with an adjustment mechanism for driving the crushing mechanism and the lever pulling mechanism to lift and lower, and the adjustment mechanism includes a mounting frame with an opening on one side, and retractable support rods are connected between the four corners of the bottom of the mounting frame and the top of the frame, and two symmetrically distributed electric telescopic rods are also connected between the frame and the mounting frame, and the crushing mechanism and the lever pulling mechanism are both mounted on the mounting frame.

[0010] Preferably, the opening side of the mounting frame has two symmetrically distributed guide rods, and the ends of the two guide rods away from the mounting frame gradually approach each other and extend to form parallel guide sections, with a guide opening for straw to be inserted between the two guide sections.

[0011] Preferably, each of the two soil-beating rods has soil-breaking cones evenly spaced along its length installed on one side facing each other.

[0012] Preferably, one side of each of the two soil-tamping rods is obliquely cut to form an inclined portion, and the two inclined portions are distributed in a figure-eight shape.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] This utility model, through the setting of a soil-beating mechanism, can beat the root of the straw during the pulling process, causing the soil carried by the straw root to fall off, thereby achieving rapid straw pulling. This not only prevents soil from being sent into the crushing mechanism with the straw, avoiding the mixing of soil into the straw fragments and facilitating the subsequent use of the straw fragments, but also ensures that the crushing mechanism can crush the straw efficiently, thus greatly improving the pulling efficiency and making the pulling device more convenient to use.

[0015] Furthermore, the soil-breaking cone can break up the soil clumps carried by the straw roots, making it easier for the soil-beating rod to knock the soil off the straw roots, greatly improving the soil-beating effect of the soil-beating rod, further facilitating the crushing and collection of straw, and improving the efficiency of the device's pole pulling.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figures 1-4 The crop straw pulling device shown includes a movable frame 1, a crushing mechanism 3, a pulling mechanism 4 and a collection box 9 set on the frame 1. The collection box 9 is located directly below the crushing mechanism 3. It also includes a soil-beating mechanism 7 for beating the roots of the straw.

[0025] The soil-beating mechanism 7 includes two symmetrically distributed and relatively movable soil-beating rods 71. Springs 73 are connected between the opposite sides of the two soil-beating rods 71 ​​and the inner wall of the frame 1. The frame 1 is also equipped with a power component that drives the two soil-beating rods 71 ​​to move relative to each other.

[0026] Specifically, the power components include mounting seats fixed on both sides of the inner wall of the frame 1, and transmission rods 72 installed on opposite sides of the two tamping rods 71. Each mounting seat is equipped with a motor 75, and each motor 75 has a sector gear 76 installed on its main shaft. Each transmission rod 72 has a tooth 77 on one side that meshes with the sector gear 76. The frame 1 has through holes through which the two transmission rods 72 pass.

[0027] As described above, when pulling crop straw, the device can be pushed to the crop planting area by the frame 1 and moved along the planting area. During the movement, the straw pulling mechanism 4 pulls the straw out of the soil and feeds it into the crushing mechanism 3. The crushing mechanism 3 then crushes the straw, and the crushed straw falls into the collection box 9, thus realizing the pulling and collection of straw.

[0028] When the pulling mechanism 4 pulls out the straw, the motor 75 drives the sector gear 76 to rotate. At this time, the sector gear 76 drives the transmission rod 72 to move through the convex tooth 77 that meshes with it. Then the transmission rod 72 moves and pushes the patting rod 71, so that the patting rod 71 stretches the spring 73 and touches the root of the straw. When the sector gear 76 does not mesh with the convex tooth 77 on the transmission rod 72, the patting rod 71 returns to its original position under the action of the spring 73. This process is repeated to realize that the patting rod 71 pats the root of the straw, so that the soil carried by the root of the straw falls off. This not only prevents the soil from being sent into the crushing mechanism 3 with the straw, avoiding the mixing of soil into the straw crushed material, but also ensures the normal operation of the crushing mechanism 3, which is conducive to the rapid pulling of the straw and greatly improves the pulling efficiency.

[0029] It should be noted that the specific structure and principle of the crushing mechanism 3 and the pulling mechanism 4 are existing technologies, and can be referred to in the prior art (authorization announcement number: CN221043782U, name: a crop straw pulling device), and will not be elaborated here.

[0030] Furthermore, to ensure that the transmission rod 72 drives the soil-beating rod 71 to move stably, such as... Figure 1 and Figure 3 As shown, a limit slider is also installed on the inner wall of the through hole, and a limit groove for the limit slider to slide is provided on the side of the transmission rod 72 away from the protrusion 77.

[0031] Furthermore, to facilitate the movement of the straw roots between the two soil-tamping rods 71, such as... Figure 1 and Figure 3 As shown, one side of each of the two soil-tamping rods 71 ​​is obliquely cut to form an inclined section, and the two inclined sections are distributed in a figure-eight shape.

[0032] Meanwhile, in this embodiment, such as Figures 1-3 As shown, the frame 1 is also equipped with an adjustment mechanism for driving the crushing mechanism 3 and the lever pulling mechanism 4 to lift and lower. The adjustment mechanism includes a mounting frame 2 with an opening on one side. The four corners at the bottom of the mounting frame 2 are connected to the top of the frame 1 by telescopic support rods 6. The frame 1 and the mounting frame 2 are also connected by two symmetrically distributed electric telescopic rods 5. The crushing mechanism 3 and the lever pulling mechanism 4 are both mounted on the mounting frame 2.

[0033] When pulling up crop straw, the height of the crushing mechanism 3 and the pulling rod mechanism 4 can be adjusted according to the height of the crop straw. That is, the mounting frame 2 is raised and lowered by the electric telescopic rod 5, so that the mounting frame 2 drives the crushing mechanism 3 and the pulling rod mechanism 4 to rise and fall. At this time, the telescopic support rod 6 rises and falls accordingly to ensure the stable raising and lowering of the mounting frame 2 until the height of the crushing mechanism 3 and the pulling rod mechanism 4 meets the height requirements of the crop straw. Then, the straw is pulled up and crushed by the crushing mechanism 3 and the pulling rod mechanism 4. This realizes the height adjustment of the crushing mechanism 3 and the pulling rod mechanism 4, which greatly improves the applicability of the pulling rod device and facilitates its use.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, two symmetrically distributed guide rods 8 are formed on the opening side of the mounting frame 2, and the ends of the two guide rods 8 away from the mounting frame 2 gradually approach each other and extend to form parallel guide parts, with a guide opening for straw to be inserted between the two guide parts.

[0035] When the device moves the pulling rod, the straw can be moved in from the feed inlet, and then moved into the pulling rod mechanism 4 under the limit of the two feed rods 8. The straw is then pulled up by the pulling rod mechanism 4, which facilitates the feeding of the device, helps to pull up the straw quickly, and further improves the pulling rod efficiency.

[0036] Additionally, in one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, each of the two soil-breaking rods 71 ​​has soil-breaking cones 74 evenly distributed along its length on one side facing each other.

[0037] As the two tamping rods 71 ​​reciprocate to tamp the roots of the straw, the tamping rods 71 ​​drive the soil-breaking cones 74 to move synchronously. Through the cooperation of the two soil-breaking cones 74, the soil clumps carried by the roots of the straw are broken up, making it easier for the tamping rods 71 ​​to tamp the soil off the roots of the straw. This greatly improves the tamping effect of the tamping rods 71, further facilitates the crushing and collection of straw, and improves the efficiency of the device.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
