Abstract
Description
Technical Field
[0001] This invention relates to the field of planting technology, specifically to a soil loosening device for sesame cultivation fields. Background Technology
[0002] Flax is an important economic crop with significant economic and edible value. It thrives in loose soil and well-drained environments. Therefore, maintaining loose and well-drained soil is crucial for flax cultivation, as it contributes to higher yields and better quality.
[0003] To meet the requirements for sesame cultivation, soil loosening and ridging are necessary before planting. This method of ridge cultivation corrects previous planting practices, not only softening and aerating the soil to promote sesame growth and development, but also keeping the back of the ridge loose and well-aerated, which is more conducive to root growth and nutrient absorption. Furthermore, this method not only increases sesame yield and quality but also improves farmers' efficiency and profitability, further promoting the sustainable development of sesame cultivation.
[0004] In ordinary planting fields, there are bound to be stones and plant roots. Since sesame has a very shallow root system, the remaining plant roots and stones in the soil will inevitably have an adverse effect on the root growth of sesame. Summary of the Invention

A power transmission shaft is penetrated through the center of one side of the middle shell. A relay gear is fixedly sleeved on the power transmission shaft near the position between the front and rear straight bevel gears. The relay gear is meshed between the front and rear straight bevel gears.
[0009] The front sleeve has multiple front arc-shaped side plates evenly spaced at both its front and rear edges. A front sleeve hole is formed through the center of the front and rear end faces of the front sleeve. The front drive shaft is fitted inside the front sleeve hole. The rear sleeve has multiple rear arc-shaped side plates evenly spaced at both its front and rear end faces. A coarse-mesh screen is fixed between each pair of rear arc-shaped side plates.

A rear sleeve hole is formed through the center of the front and rear end faces of the rear sleeve. The rear drive shaft is fitted inside the rear sleeve hole.
[0010] Preferably, front reinforcing spokes are fixedly provided at one edge position of each of the plurality of front arc-shaped side plates.
[0011] Preferably, a rear reinforcing spoke is fixedly provided at one edge position of each of the plurality of rear arc-shaped side plates.
[0012] Preferably, mounting rods are fixedly provided at the center positions of both the upper and lower sides of the central casing, and mounting flanges are fixedly provided at the ends of the multiple mounting rods away from the central casing.
[0013] Preferably, a front bushing and a rear bushing are fixedly embedded at the center positions of the front and rear end faces of the middle sleeve, respectively, and the front drive shaft and the rear drive shaft are rotatably sleeved inside the front bushing and the rear bushing, respectively.
[0014] Preferably, a power shaft sleeve is fixedly embedded in the center of one side of the middle casing, the power transmission shaft is rotatably sleeved inside the power shaft sleeve, and an annular groove is formed on the power transmission shaft near the connection position of the power shaft sleeve.
[0015] Preferably, the front drive shaft and the rear drive shaft are respectively provided with a front slot and a rear slot, the front sleeve is fixedly provided with a front locking block near the inner wall of the front sleeve hole, and the rear sleeve is fixedly provided with a rear locking block near the inner wall of the rear sleeve hole.
[0016] Preferably, the power transmission shaft has a power slot at the end away from the central housing.
[0017] Working principle: In use, the device is fixed to the output mechanism of the agricultural machinery via a mounting rod and mounting flange, with the front tilting mechanism positioned close to the direction of travel. The power transmission shaft transmits power to the central connecting mechanism. The rotating power transmission shaft drives the intermediate gear to rotate. The front and rear spur bevel gears meshing on the upper and lower sides of the intermediate gear rotate in opposite directions, thus driving the front and rear tilting mechanisms to rotate in opposite directions via the front and rear transmission shafts, respectively. Because the front tilting mechanism is positioned... Near the front, as the agricultural machinery moves forward, multiple front arc-shaped side plates of the front turning mechanism insert into the soil in sequence, turning the soil, pushing large stones to one side, and cutting the roots in the shallow soil. Then, multiple rear arc-shaped side plates of the rear turning mechanism, together with the coarse-mesh screens between them, rotate to scoop up the loosened soil. During the rotation, soil fragments leak out from the coarse-mesh screens, and the remaining large particles and stones are tilted to one side as the rear sleeve rotates. The leaked soil accumulates on the other side to form a mound.
[0018] (III) Beneficial Effects
[0019] This invention provides a soil-loosening device for sesame cultivation fields. It has the following beneficial effects:
[0020] This invention provides a soil-loosening device for sesame cultivation fields. The device is installed on an agricultural vehicle. As the machinery moves forward, multiple front arc-shaped side plates of the front turning mechanism sequentially insert into the soil, turning it over and simultaneously pushing large stones to one side and cutting roots in the shallow soil. Then, multiple rear arc-shaped side plates of the rear turning mechanism, in conjunction with coarse-mesh screens between them, rotate to scoop up the loosened soil. During rotation, soil fragments leak out through the coarse-mesh screens, while the remaining large particles and stones are tilted to one side as the rear sleeve rotates. The leaked soil accumulates on the other side, forming a ridge. This effectively loosens the soil, and the soil makes full contact with air during its descent, further improving the loosening effect. Simultaneously, it removes stones and plant roots from the soil, which is beneficial for sesame growth. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example:
[0030] like Figure 1-6 As shown, this embodiment of the invention provides a soil-loosening device for sesame cultivation fields, including a front turning mechanism 1, a middle connecting mechanism 2, and a rear turning mechanism 3. Both the front turning mechanism 1 and the rear turning mechanism 3 are made of high-manganese steel, possessing excellent bending and shear resistance, and are coated with a chromium carbide layer to enhance surface hardness and wear resistance, meeting the structural strength requirements for normal use of the device. The front turning mechanism 1 includes a front sleeve 31, the middle connecting mechanism 2 includes a middle shell 4, and the rear turning mechanism 3 includes a rear sleeve 22 and a middle shell 4. 4. A front drive shaft 9 and a rear drive shaft 11 are respectively embedded in the center of the front and rear end faces. A front straight bevel gear 15 and a rear straight bevel gear 16 are respectively fixedly sleeved on the adjacent ends of the front drive shaft 9 and the rear drive shaft 11. A power drive shaft 5 is provided through the center of one side of the middle housing 4. A relay gear 17 is fixedly sleeved on the power drive shaft 5 near the position between the front straight bevel gear 15 and the rear straight bevel gear 16. The relay gear 17 is meshed between the front straight bevel gear 15 and the rear straight bevel gear 16.
[0031] The front sleeve 31 has multiple front arc-shaped side plates 30 evenly spaced on both its front and rear edges. The front sleeve 31 has a front sleeve hole 28 through the center of its front and rear ends. The front drive shaft 9 is fitted inside the front sleeve hole 28.

The rear sleeve 22 has a rear sleeve hole 21 through the center of its front and rear ends. The rear drive shaft 11 is fitted inside the rear sleeve hole 21.
[0032] In use, the device is fixed to the output mechanism of the agricultural machinery via the mounting rod 10 and mounting flange 7. The power mechanism is connected to the power transmission shaft 5. During installation, the device can be tilted so that the axis of rotation of the device is at a certain angle to the direction of travel of the agricultural machinery, reducing the pressure exerted by the soil on the side of the device when the agricultural machinery moves forward. This allows the front turning mechanism 1 to be closer to the direction of travel of the agricultural machinery. The power transmission shaft 5 transmits power to the middle connecting mechanism 2. The rotating power transmission shaft 5 drives the intermediate gear 17 to rotate. The front straight bevel gear 15 and the rear straight bevel gear 16, which mesh on the upper and lower sides of the intermediate gear 17, rotate in opposite directions, and then transmit power through the front transmission shaft 9 and the rear transmission shaft 9, respectively. Shaft 11 drives the front turning mechanism 1 and the rear turning mechanism 3 to rotate in opposite directions. Since the front turning mechanism 1 is located near the front, as the agricultural machinery moves forward, multiple front arc-shaped side plates 30 of the front turning mechanism 1 are inserted into the soil in sequence to turn the soil, while pushing large stones to one side and cutting the roots in the shallow soil. Then, multiple rear arc-shaped side plates 23 of the rear turning mechanism 3, together with the coarse mesh screen 25 between each pair, rotate to shovel up the loosened soil. During the rotation, soil fragments are leaked out from the coarse mesh screen 25, and the remaining large particles and stones are tilted to one side as the rear sleeve 22 rotates. The leaked soil accumulates on the other side to form a soil mound.
[0033] Multiple front arc-shaped side plates 30 are each fixedly provided with front reinforcing spokes 29 at one edge position, and multiple rear arc-shaped side plates 23 are each fixedly provided with rear reinforcing spokes 24 at one edge position, thereby strengthening the structural strength of the front arc-shaped side plates 30 and rear arc-shaped side plates 23. The middle sleeve 4 is fixedly provided with mounting rods 10 at the center positions of the upper and lower sides, and multiple mounting rods 10 are fixedly provided with mounting flanges 7 at the ends away from the middle sleeve 4 for easy installation. The center positions of the front and rear end faces of the middle sleeve 4 are respectively fixedly embedded with front bushings 13 and rear bushings 14. The front drive shaft 9 and the rear drive shaft 11 are respectively rotatably sleeved inside the front bushings 13 and the rear bushings 14, making the rotation of the middle front drive shaft 9 and the rear drive shaft 11 more stable.
[0034] A power shaft sleeve 19 is fixedly embedded in the center of one side of the middle sleeve 4. The power transmission shaft 5 is rotatably sleeved inside the power shaft sleeve 19. An annular groove 18 is opened on the power transmission shaft 5 near the connection position of the power shaft sleeve 19. A front slot 8 and a rear slot 12 are respectively opened on the surface of the front transmission shaft 9 and the rear transmission shaft 11. A front locking block 27 is fixedly installed on the inner wall of the front sleeve hole 28 near the front sleeve hole 28. A rear locking block 20 is fixedly installed on the inner wall of the rear sleeve hole 21 near the rear sleeve hole 21. A power slot 6 is opened on the end of the power transmission shaft 5 away from the middle sleeve 4 to improve the stability during rotation.
