Description

Technical Field

[0001] This invention relates to the field of soil loosening equipment technology, and in particular to a green belt construction device and construction method. Background Technology

[0002] Urban roads typically feature green belts, which not only separate motor vehicle lanes from non-motor vehicle lanes but also improve the urban road environment and reduce dust and noise. Because these green belts are planted with various trees and flowers, agricultural machinery is needed to till the soil, loosen it, and fertilize it to ensure the growth and development of these plants.

[0003] Patent document CN114710982B discloses a soil loosening device for municipal road greening. This device includes a linkage push plate with multiple insertion rods mounted on one side. Each insertion rod has a slanted pointed block on both sides near one end, and a soil loosening mechanism is connected to one side of each slanted pointed block. The soil loosening mechanism includes a connecting pointed block on one side of each slanted pointed block. When the insertion rods enter the gaps between plants, the slanted pointed blocks and the connecting pointed block contact the plants, causing the plants to move laterally along the slanted surfaces of the blocks. Because the insertion rods can reciprocate, they cause the internal longitudinal insertion strips, transverse insertion strips, and soil loosening pointed rods to vibrate back and forth, thus loosening the soil between the plants. However, due to the varying hardness of different soils, this soil loosening device is less effective when applied to harder soils. Summary of the Invention

[0004] Therefore, it is necessary to provide a green belt construction device and construction method to address the technical problem that current soil loosening devices have poor soil loosening effect when applied to harder soil.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A greenbelt construction device includes a mobile vehicle body with a soil loosening device rotatably connected to it. The soil loosening device includes a drive motor and multiple rotating shafts. The drive motor can drive the multiple rotating shafts to rotate synchronously. The rotating shafts extend in a front-rear direction and are provided with a first cam mechanism and a second cam mechanism. The second cam mechanism is located in front of the first cam mechanism. The rotation of the rotating shaft can drive the first cam mechanism and the second cam mechanism to rotate synchronously in opposite directions. The first cam mechanism includes a first cam with a first inclined surface on its front side. The second cam mechanism includes a second cam with a second inclined surface on its rear side. Both the first and second inclined surfaces are inclined in a left-right direction, with the inclination directions of the first and second inclined surfaces being opposite.

[0007] Furthermore, the first cam mechanism also includes a rotating sleeve, and a transmission mechanism is provided between the rotating sleeve and the rotating shaft. The rotating shaft drives the rotating sleeve to rotate in the opposite direction through the transmission mechanism. A first fixed ring is fixed on the rotating sleeve, the first cam is sleeved on the first fixed ring, and a first spring is provided between the first cam and the first fixed ring.

[0008] Furthermore, a rotating tooth is fixedly provided on the rotating shaft, and an internal gear ring is provided on the inner circumferential surface of the rotating sleeve. The transmission mechanism is a double gear structure, which consists of a first gear and a second gear integrally formed. The first gear meshes with the rotating tooth, and the second gear meshes with the internal gear ring. The gear ratio between the rotating tooth and the first gear is the same as the gear ratio between the internal gear ring and the second gear.

[0009] Furthermore, the second cam mechanism also includes a second fixed ring, which is fixedly mounted on the rotating shaft. The second cam is sleeved on the second fixed ring, and a second spring is provided between the second cam and the second fixed ring.

[0010] Furthermore, the soil loosening device includes a mounting base, the bottom of which is provided with multiple vertically extending support seats, each of which is provided with a drive shaft. The rotating shaft corresponds one-to-one with the drive shaft and is connected in transmission. Each drive shaft is provided with a transmission gear, and the multiple drive shafts achieve synchronous rotation through the transmission gears.

[0011] Furthermore, the drive motor is mounted on the mounting base, and the drive shaft of the drive motor rotates synchronously with one of the transmission shafts.

[0012] Furthermore, the support base is provided with a horizontal support rod, a vertical support rod is fixedly connected to the horizontal support rod, a fixed shaft is provided on the vertical support rod, and the double gear structure is rotatably mounted on the fixed shaft.

[0013] Furthermore, the end of the rotating shaft is provided with a tapered guide.

[0014] Furthermore, a swinging component is hinged to the mobile vehicle body, which can swing up and down. A limiting plate is also provided on the mobile vehicle body, which can limit the swinging amplitude of the swinging component. The swinging component is provided with a left and right moving mechanism, and the left and right moving mechanism is provided with a front and back reciprocating mechanism. The soil loosening device is connected to the front and back reciprocating mechanism in a transmission connection.

[0015] A method for constructing green belts, using the aforementioned green belt construction device, includes the following steps;

[0016] First, push the mobile vehicle across the designated green belt, and adjust the angle of the loosening device by using the swinging parts to keep it parallel to the soil to be loosened;

[0017] Second, adjust the left and right position of the loosening device by moving it left and right, so that the loosening device is aligned with the soil to be loosened.

[0018] Third, start the reciprocating mechanism and drive motor to make the soil loosening device move back and forth. At the same time, the rotating shaft drives the first cam and the second cam to rotate in opposite directions synchronously to break up and loosen the soil.

[0019] The beneficial effects of this invention are:

[0020] The green belt construction device and method provided by the present invention, when the shaft of the soil loosening device rotates, the first cam and the second cam rotate synchronously in opposite directions. Since the first cam and the second cam are eccentrically set, their sides can act as striking surfaces to impact the soil when they rotate, making hard soil easier to break and improving the soil loosening effect. At the same time, the impact of the first cam and the second cam with the soil can cause the soil loosening device to vibrate, preventing soil from adhering to the soil loosening device.

[0021] Secondly, both the first and second cams are connected to springs, so that the first and second cams can be displaced during rotation to avoid plant roots and stones, thus preventing damage to plant roots and stones in the soil from damaging the first and second cams and extending the service life of the soil loosening device.

[0022] Third, the first cam and the second cam rotate in opposite directions, and the first cam has a first inclined surface on its front side and the second cam has a second inclined surface on its rear side. The first and second inclined surfaces are inclined in opposite directions. When the second cam rotates, the second inclined surface pushes the soil from right to left; then the rotation of the first cam will push the soil from left to right through the first inclined surface, which can keep the soil surface flat. The soil driven by the first and second inclined surfaces will collide with each other, causing the hard soil to break up and further improving the soil loosening effect. Attached Figure Description

[0040] like Figures 1 to 13 As shown, an embodiment of the present invention provides a green belt construction device, including a mobile vehicle 100, on which a soil loosening device 200 is rotatably connected. The soil loosening device 200 includes a drive motor 206 and multiple rotating shafts 207. The drive motor 206 can drive the multiple rotating shafts 207 to rotate synchronously. The rotating shafts 207 extend in a front-rear direction and are provided with a first cam mechanism and a second cam mechanism. The second cam mechanism is located in front of the first cam mechanism. The rotation of the rotating shaft 207 can drive the first cam mechanism and the second cam mechanism to rotate synchronously in opposite directions. The first cam mechanism includes a first cam 211, and a first inclined surface 215 is provided on the front side of the first cam 211. The second cam mechanism includes a second cam 220, and a second inclined surface 223 is provided on the rear side of the second cam 220. Both the first inclined surface 215 and the second inclined surface 223 are inclined in a left-right direction, and the inclination directions of the first inclined surface 215 and the second inclined surface 223 are opposite. In this embodiment, multiple sets of the first cam mechanism and the second cam mechanism are provided. In other embodiments, only one set of the first cam mechanism and the second cam mechanism is provided.

[0041] In one embodiment, the first cam mechanism further includes a rotating sleeve 210. A transmission mechanism 230 is provided between the rotating sleeve 210 and the rotating shaft 207. The rotating shaft 207 drives the rotating sleeve 210 to rotate in the opposite direction through the transmission mechanism 230. A first fixing ring 213 is fixed on the rotating sleeve 210. The first cam 211 is sleeved on the first fixing ring 213, and a first spring 212 is provided between the first cam 211 and the first fixing ring 213. The rotating sleeve 210 is axially engaged with the rotating shaft 207. The rotating shaft 207 is provided with a plurality of annular protrusions 2072, and the rotating sleeve 210 is axially engaged with the annular protrusions 2072.

[0042] In one embodiment, a rotating gear 233 is fixedly provided on the rotating shaft 207, and an internal gear ring 214 is provided on the inner circumferential surface of the rotating sleeve 210. The transmission mechanism 230 is a double-gear structure, consisting of an integrally formed first gear 231 and second gear 232. The first gear 231 meshes with the rotating gear 233, and the second gear 232 meshes with the internal gear ring 214. The gear ratio between the rotating gear 233 and the first gear 231 is the same as the gear ratio between the internal gear ring 214 and the second gear 232. This ensures that the first cam 211 and the second cam 220 rotate at the same speed, so that the first inclined surface 215 and the second inclined surface 223 can simultaneously contact the soil.

[0043] In one embodiment, the second cam mechanism further includes a second fixed ring 222, which is fixedly mounted on the rotating shaft 207. The second cam 220 is sleeved on the second fixed ring 222, and a second spring 221 is provided between the second cam 220 and the second fixed ring 222.

[0044] In one embodiment, the soil loosening device 200 includes a mounting base. The bottom of the mounting base has multiple vertically extending support seats 201. Each support seat 201 contains a drive shaft 209. A rotating shaft 207 corresponds one-to-one with the drive shaft 209 and is connected for transmission. Each drive shaft 209 is equipped with a transmission gear 208, and the multiple drive shafts 209 rotate synchronously through the transmission gears 208. One end of the drive shaft 209 has a second transmission tooth 2091, and one end of the rotating shaft 207 has a first transmission tooth 2071. The first transmission tooth 2071 meshes with the second transmission tooth 2091.

[0045] In one embodiment, the drive motor 206 is mounted on a mounting base, and the drive shaft of the drive motor 206 rotates synchronously with one of the transmission shafts 209.

[0046] In one embodiment, the support base 201 is provided with a horizontal support rod 202, and a vertical support rod 203 is fixedly connected to the horizontal support rod 202. The vertical support rod 203 is provided with a fixed shaft, and the double gear structure is rotatably mounted on the fixed shaft.

[0047] In one embodiment, the end of the rotating shaft 207 is provided with a tapered guide 204, which is used to guide the loosening device 200 to move smoothly between the plants.

[0048] In one embodiment, a swing member 102 is hinged to the mobile vehicle body 100, and the swing member 102 can swing up and down. A limiting plate 101 is also provided on the mobile vehicle body 100, which can limit the swing amplitude of the swing member 102. A left-right moving mechanism 103 is provided on the swing member 102, and a front-back reciprocating mechanism 104 is provided on the left-right moving mechanism 103. The soil loosening device 200 is connected to the front-back reciprocating mechanism 104. In this embodiment, the structures of the swing member 102, the left-right moving mechanism 103, and the front-back reciprocating mechanism 104 are all prior art. The swing member 102 and the left-right moving mechanism 103 can be found in patent document CN114710982B, and will not be described in detail here. The front-back reciprocating mechanism 104 is a crank-connecting rod mechanism. A moving rod 205 is provided on the mounting base, and the front-back reciprocating mechanism 104 drives the moving rod 205 to move back and forth.

[0049] The mobile vehicle body 100 is equipped with a push rod 105 and wheels 106 at the bottom. The push rod 105 drives the mobile vehicle body 100 to move within the green belt.

[0050] The working principle and process of the green belt construction device of the present invention are as follows:

[0051] First, the vehicle body 100 is moved to span the designated green belt. Then, the angle of the loosening device 200 is adjusted by the swinging component 102 to keep it parallel to the soil to be loosened. The left and right positions of the loosening device 200 are adjusted by the left and right moving mechanism 103 to align the loosening device 200 with the soil to be loosened. The reciprocating mechanism 104 and the drive motor 206 are activated to make the loosening device 200 move back and forth. At the same time, the drive motor 206 drives one of the transmission shafts 209 to rotate. The transmission shaft 209 drives all the transmission shafts 209 to rotate synchronously through the transmission gear 208. Then, all the rotating shafts 207 rotate. The rotation of the rotating shafts 207 drives the first cam 211 and the second cam 220 to rotate synchronously in opposite directions. The first cam 211 and the second cam 220 rotate at the same speed. In this way, the first inclined plane 215 and the second inclined plane 223 can simultaneously impact the soil and break it up. Because the first cam 211 and the second cam 220 are eccentrically positioned, their sides can act as striking surfaces to impact the soil during rotation, making hard soil easier to break up and improving the soil loosening effect. Simultaneously, the impact of the first cam 211 and the second cam 220 with the soil causes the soil loosening device 200 to vibrate, preventing soil from adhering to the device. Both the first cam 211 and the second cam 220 are connected to springs, allowing them to shift during rotation to avoid plant roots and stones, preventing damage to plant roots and stones in the soil. Damage to the second cam 220 extends the service life of the soil loosening device 200. The first cam 211 and the second cam 220 rotate in opposite directions. The first cam 211 has a first inclined surface 215 on its front side, and the second cam 220 has a second inclined surface 223 on its rear side. The first inclined surface 215 and the second inclined surface 223 are inclined in opposite directions. When the second cam 220 rotates, the second inclined surface 223 pushes the soil from right to left. Then the rotation of the first cam 211 will push the soil from left to right through the first inclined surface 215, which can keep the soil surface flat. The soil driven by the first inclined surface 215 and the second inclined surface 223 will collide with each other, causing the hard soil to break up and further improving the soil loosening effect.

[0052] A method for constructing green belts, using the aforementioned green belt construction device, includes the following steps;

[0053] First, push the mobile vehicle 100 across the designated green belt, and adjust the angle of the loosening device 200 by the swinging component 102 so that it is parallel to the soil to be loosened;

[0054] Second, the left and right positions of the loosening device 200 are adjusted by the left and right moving mechanism 103 so that the loosening device 200 is aligned with the soil to be loosened.

[0055] Third, the reciprocating mechanism 104 and the drive motor 206 are activated to make the soil loosening device 200 move back and forth. At the same time, the rotating shaft 207 rotates, driving the first cam 211 and the second cam 220 to rotate synchronously in opposite directions, thus breaking up and loosening the soil.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
