Description

Technical Field

[0001] This application relates to the field of soil loosening devices, and more particularly to soil loosening devices based on crop planting. Background Technology

[0002] Loosening the soil is an important management practice in agricultural production, significantly impacting crop growth and development. It is typically done before planting to improve soil aeration, ensuring root respiration and microbial activity, providing sufficient oxygen to promote root development, and suppressing weed growth.

[0003] Current soil loosening devices include electric and manual types, with manual devices being more commonly used by individuals. Existing manual soil loosening devices for crop planting consist of an operating rod with a connecting plate fixed to its bottom. Several loosening teeth are fixedly connected to the bottom of the connecting plate. During loosening, the loosening teeth are inserted into the soil, and then the soil is loosened. However, certain drawbacks exist. When loosening the soil to one side, there is no support point, making operation laborious; furthermore, cleaning the loosening teeth is inconvenient. After a period of use, it becomes difficult to reinsert the loosening teeth into the soil, requiring manual cleaning, which wastes time and poses certain safety hazards. Therefore, this application proposes a soil loosening device for crop planting. Utility Model Content

[0004] The purpose of this application is to address the technical problems pointed out in the background art by proposing a soil loosening device for crop planting.

[0005] The technical solution of this application is as follows: a soil loosening device for crop planting, including an installation plate and an operating rod fixedly connected to its upper end, a plurality of soil loosening teeth fixedly connected to the bottom end of the installation plate, and further including: a bent rod connected to the side of the installation plate, a force-bearing plate fixedly connected to the bottom end of the bent rod, and a soil cleaning mechanism for cleaning the plurality of soil loosening teeth provided on the installation plate.

[0006] Preferably, the connection end of the bent rod and the mounting plate is provided with a threaded groove, and the side wall of the mounting plate is provided with a threaded hole. When the bent rod and the mounting plate are installed, the threaded hole and the threaded groove are aligned and fixed by bolts.

[0007] Preferably, the end of the force-bearing plate away from the bending rod is an arc-shaped part, and the force-bearing plate maintains a distance from the ground when the loosening rod is perpendicular to the ground.

[0008] Preferably, the soil cleaning mechanism includes a pair of transmission rods slidably inserted into the mounting plate. The bottom ends of the two transmission rods are connected to a transmission plate. The bottom end of the transmission plate is fixedly connected to a scraper by two push rods. The transmission plate and the scraper are slidably sleeved on the side walls of several loosening toothed rods. The transmission plate slides downward, driving the two push rods to push the scraper downward, thus cleaning the side walls of the loosening toothed rods.

[0009] Preferably, the soil-clearing mechanism further includes a pair of straight cylinders fixedly connected to the upper end of the mounting plate. The two straight cylinders are respectively covered on the outside of the two transmission rods, and a spring-loaded component is provided inside each of the two straight cylinders.

[0010] Preferably, the spring-loaded component includes a spring disposed inside the straight cylinder, a support ring located inside the straight cylinder is fixedly connected to the side wall of the transmission rod, the bottom end of the spring is fixedly connected to the mounting plate, and the upper end of the spring is fixedly connected to the support ring;

[0011] A limit ring is fixedly connected to the inner wall of the upper end of the straight cylinder to limit the position of the support ring.

[0012] Preferably, the upper ends of the two transmission rods are fixedly connected to a U-shaped connecting rod, and the bottom end of the U-shaped connecting rod is fixedly connected to a foot rod.

[0013] Preferably, a pair of handles are fixedly connected to the upper end of the operating lever, and the outer walls of both handles are covered with protective sleeves made of silicone.

[0014] Compared with the prior art, this application has the following beneficial technical effects:

[0015] This application incorporates a soil-cleaning mechanism on the mounting plate. Stepping on the foot pedal moves the scraper downwards, cleaning the soil on the side walls of several loosening tooth bars. When the foot is released, the scraper returns to its original position due to the rebound action of the spring mechanism, allowing the loosening tooth bars to quickly return to their loosening state. The soil-cleaning mechanism is designed to quickly clean the loosening tooth bars, maintaining their original loosening effect and improving the efficiency of soil loosening.

[0016] By connecting a bent rod to one side of the mounting plate, and installing a load-bearing plate at the bottom of the bent rod, a support point is provided during the loosening process, which reduces the difficulty of loosening the soil and allows the soil to easily tilt to one side.

[0029] Example

[0030] like Figs. 1-3 As shown, the soil loosening device for crop planting proposed in this application includes a mounting plate 2 and an operating rod 1 fixedly connected to its upper end. A pair of handles 8 are fixedly connected to the upper end of the operating rod 1, and both handles 8 are covered with protective sleeves made of silicone material, which can provide some protection for the hands. Several loosening toothed rods 5 are fixedly connected to the bottom end of the mounting plate 2. The loosening toothed rods 5 are inserted into the soil to loosen it. The device also includes a bent rod 3 connected to the side of the mounting plate 2. The bent rod 3 has a threaded groove at its connection end with the mounting plate 2, and a threaded hole is formed on the side wall of the mounting plate 2. When the bent rod 3 is installed with the mounting plate 2, the threaded hole and threaded groove are aligned and fixed with bolts 7. The bent rod 3 can be removed according to individual needs by unscrewing the bolts 7, making disassembly and assembly very convenient. A force-bearing plate 4 is fixedly connected to the bottom end of the bent rod 3. The end of the force-bearing plate 4 away from the bent rod 3 is arc-shaped. When the loosening tooth rod 5 is tilted to one side, the force-bearing plate 4 contacts the ground, increasing the contact area between the force-bearing plate 4 and the ground and preventing the force-bearing plate 4 from partially inserting into the soil. When the loosening tooth rod 5 is perpendicular to the ground, the force-bearing plate 4 maintains a distance from the ground, and the force-bearing plate 4 will not obstruct the insertion of the loosening tooth rod 5 into the soil. The mounting plate 2 is equipped with a soil-cleaning mechanism 6 for cleaning several loosening tooth rods 5.

[0031] Specifically, the soil-cleaning mechanism 6 includes a pair of transmission rods 61 slidably inserted into the mounting plate 2. The upper ends of the two transmission rods 61 are fixedly connected to a U-shaped connecting rod 67, and the bottom end of the U-shaped connecting rod 67 is fixedly connected to a foot rod 68. The bottom ends of the two transmission rods 61 are connected to a transmission plate 63. The bottom end of the transmission plate 63 is fixedly connected to a scraper 65 via two push rods 64. Both the transmission plate 63 and the scraper 65 are slidably fitted onto the side walls of several loosening toothed rods 5. The downward sliding of the transmission plate 63 drives the two push rods 64 to push the scraper 65 downward, cleaning the side walls of the loosening toothed rods 5 and scraping off the soil. The soil-cleaning mechanism 6 also includes a pair of straight cylinders 62 fixedly connected to the upper end of the mounting plate 2. The two straight cylinders 62 are respectively covered on the outside of the two transmission rods 61. Each of the two straight cylinders 62 is equipped with a spring-loaded component 66, which allows the scraper 65 to quickly return to its original position.

[0032] Furthermore, the spring-loaded component 66 includes a spring 661 disposed inside the straight cylinder 62. The spring 661 is sleeved on the outside of the transmission rod 61. A support ring 662 located inside the straight cylinder 62 is fixedly connected to the side wall of the transmission rod 61. The bottom end of the spring 661 is fixedly connected to the mounting plate 2, and the upper end of the spring 661 is fixedly connected to the support ring 662. A limit ring 663 is fixedly connected to the inner wall of the upper end of the straight cylinder 62 for limiting the support ring 662.

[0033] The working principle of this embodiment is as follows: When using this device to loosen the soil, hold the handle 8 and press it vertically downwards to insert several loosening rods 5 into the soil. Then, tilt the device towards the direction of the bent rod 3 and forcefully push the soil upwards through the several loosening rods 5 (the loosening rods 5 tilt to one side). During this step, the force plate 4 contacts the ground, which plays a supporting role and makes it easier for the several loosening rods 5 to tilt to one side, preventing them from falling into the void.

[0034] After the device has been used for a period of time, the foot pedal 68 can be stepped on. This, via the U-shaped connecting rod 67, drives two transmission rods 61 downwards. The transmission rods 61 then move the transmission plate 63 downwards, which in turn pushes the scraper 65 downwards via two push rods 64. This scrapes away the soil from the side walls of several loosening toothed rods 5, keeping their surfaces smooth so that the soil can be smoothly deposited into the soil, improving loosening efficiency. When the foot is released, the rebound force of two springs 661 causes the two transmission rods 61 to move upwards back to their original positions, which in turn returns the transmission plate 63 to its original position. Finally, the two push rods 64 drive the scraper 65 back to its original position, automatically restoring the loosening toothed rods 5 to their loosening state.

[0035] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
