DETAILED DESCRIPTION

[0026] See also Figures 1 to 5As shown, the utility model provides a soil remediation agent spraying device, including a base 1, two discharge boxes 3, a water pump 4 and a driving device 5. The inner side of the base 1 is provided with a mounting cavity 11, and the front side of the base 1 is provided with a sliding groove 12, which is communicated with the mounting cavity 11. A liquid storage cylinder 2 is fixed on the top of the base 1; a group of nozzles 31 are provided at the bottom of each of the discharge boxes 3, and one end of the two discharge boxes 3 is rotatably installed at the front end of the base 1 so that the other ends of the two discharge boxes 3 have a movable stroke of approaching and moving away from each other; the water pump 4 is arranged between the liquid storage cylinder 2 and the discharge box 3, and is used to pump the liquid inside the liquid storage cylinder 2 into the discharge box 3; the driving device 5 includes a support plate 51, a moving block 52 , two rotating shafts 53, two first gears 54, two first racks 55 and a driver 56, the support plate 51 is fixed above the sliding groove 12, the two rotating shafts 53 pass through the support plate 51 and are rotatably connected to the support plate 51, the upper ends of the two rotating shafts 53 are fixedly connected to the two discharging boxes 3, the lower ends of the two rotating shafts 53 are fixedly connected to the two first gears 54, the moving block 52 is slidably connected in the sliding groove 12, the two first racks 55 are fixed on the two side walls of the moving block 52, the first racks 55 located on the same side are meshed with the first gear 54, the driver 56 is arranged in the mounting cavity 11 and connected to the moving block 52, and is used to drive the moving block 52 to move forward and backward.

[0027] When the moving block 52 is driven to move forward and backward by the driver 56, the first rack 55 on the moving block 52 drives the corresponding first gear 54 to rotate, thereby driving one end of the discharge box 3 to rotate through the rotating shaft 53, so that the other ends of the two discharge boxes 3 are close to each other or away from each other. When the two discharge boxes 3 are close to each other or away from each other, the water pump 4 draws the liquid in the liquid storage cylinder 2 into the discharge box 3, and then sprays the liquid on the soil to be repaired through the two groups of nozzles 31 on the discharge box 3. The spraying range is large, and the spraying range can be further expanded by moving the device.

[0028] Specifically, the input end of the water pump 4 is connected to the liquid storage cylinder 2 through a connecting pipe 41, the output end of the water pump 4 is connected to a discharge pipe 42, the other side of the discharge pipe 42 is connected to a two-way flow divider 43, and the two output ends of the two-way flow divider 43 are respectively fixedly connected to the two discharge boxes 3 through hoses 44. Preferably, the hose 44 adopts a foldable design, so that when the two discharge boxes 3 rotate, the hose 44 can perform corresponding stretching, contraction and bending actions according to the change of the position of the discharge box 3.

[0029] Here, the bidirectional shunt 43 is an application of the prior art, and the specific structure is not described in detail here.

[0030] Furthermore, at least two rotating rods 57 are passed through and rotatably connected to the left and right sides of the base 1, and the two rotating rods 57 are arranged at intervals in the front-back direction, and rollers 58 are fixedly connected to the two ends of the rotating rods 57. The rollers 58 are provided to facilitate the movement of the device.

[0031] In this embodiment, the driver 56 includes a connecting frame 561, a half gear 562 and two second racks 563 matched with the half gear 562. The connecting frame 561 is sleeved on the outer side of the rotating rod 57 located at the front side. The front end of the connecting frame 561 is fixedly connected to the moving block 52. The half gear 562 is fixed on the rotating rod 57. The two second racks 563 are respectively fixed on the inner wall of the connecting frame 561 just above and just below the half gear 562 and are perpendicular to the axis of the rotating rod 57. When the half gear 562 rotates, it meshes with one of the second racks 563. Preferably, the length of the second rack 563 is equal to half the circumference of the half gear 562.

[0032] The half gear 562 corresponds to the position of the two second racks 563. When the half gear 562 rotates to the upper side, it meshes with the upper second rack 563. At this time, the half gear 562 is separated from the lower second rack 563, so there is no interference between the teeth and the tooth grooves. When the half gear 562 flips to the lower side, it meshes with the lower second rack 563 and the above-mentioned action process will also occur. When the half gear 562 meshes with one of the second racks 563 during the rotation process, it drives the connection frame 561 and the moving block 52 forward. When the half gear 562 meshes with the other second rack 563, it drives the connection frame 561 and the moving block 52 backward, thereby driving the moving block 52 to complete the reciprocating motion.

[0033] In other embodiments, the driver 56 may also directly install an electric telescopic rod in the installation cavity 11 , connect the driver 56 to the moving block 52 through the electric telescopic rod, and utilize the extension and retraction of the electric telescopic rod to drive the moving block 52 to move forward and backward.

[0034] Furthermore, a turning rod 6 extending up and down is rotatably provided inside the liquid storage cylinder 2, and a plurality of stirring rods 61 are fixedly connected to the surface of the turning rod 6. Specifically, a feeding pipe 21 is fixedly connected to the top of the liquid storage cylinder 2.

[0035] When in use, liquid medicine is injected into the liquid storage cylinder 2 through the feed pipe 21, and the rotating flip rod 6 drives the multiple groups of stirring rods 61 to rotate and stir the liquid medicine inside the liquid storage cylinder 2, so that the liquid medicine is fully mixed.

[0036] Furthermore, the flip rod 6 extends downward into the installation cavity 11, and a driven bevel gear 10 is fixed to the bottom of the flip rod 6; a driving rod 7 is rotatably provided on the left and right side walls of the installation cavity 11, and the driving rod 7 is arranged on the lower side of the flip rod 6, and an active bevel gear 9 is provided on the driving rod 7, and the active bevel gear 9 is meshed with the driven bevel gear 10, and a synchronous pulley is installed on the driving rod 7 and one of the rotating rods 57, and a synchronous belt is meshed with the two synchronous pulleys.

[0037] When the roller 58 rotates, the rotating rod 57 is driven to rotate, and then the driving rod 7 is driven to rotate in the same direction through the cooperation of the synchronous pulley and the transmission belt 8, and the flip rod 6 is rotated through the transmission of the active bevel gear 9 and the driven bevel gear 10. The above linkage mode is driven by the rotation of the roller 58, so that the medicine can be stirred without an additional driver 56, so that the whole device can be operated in places where outdoor line connection is inconvenient.

[0038] Furthermore, at least one of the rollers 58 is a hub motor. The hub motor drives the rotating rod 57 to rotate, which can not only drive the other rollers 58 to rotate, so that the device moves, thereby further expanding the spraying range of the liquid medicine, but also drive the rotating rod 57 to drive the moving block 52 to move forward and backward to drive the discharging box 3 to rotate, thereby expanding the spraying range and uniformity of the liquid medicine, and can also drive the stirring rod 61 to rotate to achieve full mixing of the liquid medicine.

[0039] Furthermore, a pair of push handles 13 are fixedly connected to the rear end of the base 1. By providing the push handles 13, it is convenient for the staff to push the device to move.

[0040] In other embodiments, when in use, the device can also be connected to the device by a towing vehicle through a towing rope, and then the towing vehicle is started to drive the entire device to move at a low speed, while the staff holds the push handle 13 to control the direction.

[0041] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
