A transmission shaft is provided in each support seat, and the rotating shaft corresponds to the transmission shaft one by one and is transmission connected. The transmission shaft is provided with a transmission gear, and multiple transmission shafts achieve synchronous rotation through the transmission gear.

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

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

[0049] The moving vehicle body 100 is provided with a pushing rod 105 , and the bottom of the moving vehicle body 100 is provided with wheels 106 , and the moving vehicle body 100 is driven to move in the green belt by the pushing rod 105 .

[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 make it span across the designated green belt, and then the angle of the loosening device 200 is adjusted by the swinging member 102 so that it is 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 so that the loosening device 200 is aligned with the soil to be loosened; the front and rear reciprocating mechanism 104 and the driving motor 206 are started to make the loosening device 200 reciprocate back and forth, and at the same time, the driving motor 206 drives one of the transmission shafts 209 to rotate, and the transmission shaft 209 drives all the transmission shafts 209 to rotate synchronously through the transmission gear 208, and then all the rotating shafts 207 rotate, and the rotation of the rotating shaft 207 drives the first cam 211 and the second cam 220 to rotate synchronously in the opposite direction, and the first cam 211 and the second cam 220 have the same rotation speed, so that the first inclined surface 215 and the second inclined surface 223 can hit the soil at the same time to crush the soil. Since the first cam 211 and the second cam 220 are eccentrically arranged, the side surfaces of the first cam 211 and the second cam 220 can be used as striking surfaces to strike the soil when they rotate, so that the hard soil is more easily broken and the soil loosening effect is improved; at the same time, the collision of the first cam 211 and the second cam 220 with the soil can cause the loosening device 200 to vibrate, thereby preventing the soil from adhering to the loosening device 200; the first cam 211 and the second cam 220 are both connected to springs, so that the first cam 211 and the second cam 220 can be displaced during the rotation process to avoid plant roots and stones, thereby avoiding damage to the plant roots and the impact of stones in the soil on the first cam 211 and the second cam The second cam 220 is damaged, thereby extending the service life of the loosening device 200; the first cam 211 and the second cam 220 rotate in opposite directions, and a first inclined surface 215 is provided on the front side of the first cam 211, and a second inclined surface 223 is provided on the rear side of the second cam 220. The first inclined surface 215 and the second inclined surface 223 are inclined in opposite directions. In this way, 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, and the soil driven by the first inclined surface 215 and the second inclined surface 223 will collide with each other, so that the hard soil is broken, further improving the loosening effect.

[0052] A green belt construction method, using the green belt construction device mentioned above, comprises the following steps:

[0053] First, the mobile vehicle 100 is pushed to make it cross the designated green belt, and the angle of the loosening device 200 is adjusted by the swing member 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 forward and backward reciprocating mechanism 104 and the driving motor 206 are started to make the loosening device 200 move forward and backward, and at the same time, the rotation of the rotating shaft 207 drives the first cam 211 and the second cam 220 to rotate synchronously in the opposite direction to break and loosen the soil.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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 above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
