DETAILED DESCRIPTION

[0027] The utility model will be described in detail below with reference to the drawings. The description herein is only based on the preferred embodiments of the utility model, and other modes capable of realizing the utility model can be conceived by those skilled in the art on the basis of the preferred embodiments, and the other modes also fall within the scope of the utility model.

[0028] Referring to Figures 1-5 The embodiment provides a seedling raising production line earthing machine, which comprises a bin 100, which is provided with an earthing opening 101, and a bin door 110 provided at the earthing opening 101 and capable of being opened and closed; a controller, a detection unit 310, a driving assembly and a synchronous movement assembly 330, the driving assembly is connected with the bin door 110 and capable of driving the bin door 110 to open and close; the synchronous movement assembly 330 is connected with the driving assembly, and the synchronous movement assembly 330 moves synchronously with the bin door 110; the detection unit 310 is arranged close to the synchronous movement assembly 330 and used for detecting the movement parameters of the synchronous movement assembly 330; and the controller is electrically connected with the detection unit 310 and used for calculating the opening and closing size of the bin door 110 according to the movement parameters of the synchronous movement assembly 330. The movement parameters of the synchronous movement assembly 330 are indirectly measured by the detection unit 310, and the opening and closing size of the bin door 110 is calculated by the controller, so that the detection unit 310 directly measures the opening and closing size of the bin door 110 is avoided, even if the bin door 110 is shielded by soil at the position of the earthing opening 101, the opening and closing size of the bin door 110 can be accurately calculated by the detection unit 310 through indirect measurement of the movement parameters of the synchronous movement assembly 330. When the bin door 110 is provided with a conveying belt, the distance between the bin door 110 and the conveying belt can be accurately controlled.

[0029] In some embodiments, as Figure 2 shown, the driving assembly comprises a first driving member 360, a driven shaft 320 and a gear and rack assembly, the first driving member 360 is connected with the driven shaft 320, and the bin door 110 is connected with the driven shaft 320 through the gear and rack assembly. Specifically, the gear and rack assembly comprises a driven gear 340 mounted on the driven shaft 320 and a driven rack 350 fixedly mounted on the bin door 110, and rotation of the driven gear 340 is converted into linear motion of the driven rack 350. The synchronous movement assembly 330 is a synchronous tooth, the synchronous tooth is mounted on the driven shaft 320, and the detection unit 330 is used for detecting the number of teeth of the synchronous tooth. The first driving member 360 drives the driven shaft 320 to rotate, and the driven shaft 320 drives the gear and rack assembly to move, so that the bin door 110 moves linearly and the opening and closing size of the bin door 110 is adjusted. The synchronous tooth is mounted on the driven shaft 320, and the synchronous tooth rotates synchronously when the driven shaft 320 rotates.

[0030] It is understood that the synchronous motion component 330 can be replaced by other mechanical structures besides the synchronous teeth. For example, a synchronous pulley can be installed on the driven shaft 320, replacing the synchronous teeth in the previous embodiment. A synchronous belt and driven pulley are installed outside the door 110. The synchronous pulley drives the synchronous belt to move, and the detection unit 310 detects the movement distance of the synchronous belt to calculate the opening and closing size of the door 110. It is understood that the detection unit 310 can detect not only the movement distance of the synchronous belt but also the rotation distance or angle of the synchronous pulley, and also the rotation distance or angle of the driven pulley. Furthermore, the synchronous motion component 330 can also use a synchronous gear, replacing the synchronous teeth in the previous embodiment. A synchronous rack is installed outside the door 110. The rotation of the synchronous gear drives the synchronous rack to move linearly, and the detection unit 310 detects the movement distance of the synchronous rack. It is understood that the detection unit 310 can detect not only the movement distance of the synchronous rack but also the rotation distance or number of teeth of the synchronous gear, and also the number of teeth moved by the synchronous rack. It should be noted that, in addition to the mechanical structure mentioned above, the synchronous motion component 330 can also adopt other mechanical structures, as long as they can indirectly measure the opening and closing size of the compartment door 110.

[0031] In some embodiments, such as Figure 3 As shown, a spare handle 370 is connected to one end of the driven shaft 320. The spare handle 370 and the first drive component 360 independently drive the driven shaft 320 to rotate. The spare handle 370 serves as a backup component for driving the driven shaft 320, and can replace the first drive component 360 when it malfunctions or stops working. The operator can manually adjust the opening and closing size of the door 110 to meet the needs of different thicknesses of soil covering. The spare handle 370 enhances the soil covering machine's ability to respond to unexpected situations.

[0032] In some embodiments, such as Figure 4 As shown, the soil covering machine also includes a conveying mechanism 200, which is located at the bottom of the hopper 100. A hopper door 110 is positioned corresponding to the output end of the conveying mechanism 200. The hopper door 110 moves closer to or further away from the conveying plane of the conveying mechanism 200 via a drive assembly. Specifically, the conveying mechanism 200 includes a conveyor belt 220 and a frame 210. The frame 210 is located on both sides of the conveyor belt 220, and the bottom of the hopper 100 is mounted on the two side frames 210. The conveying plane is the surface of the conveyor belt 220. By controlling the distance between the hopper door 110 and the surface of the conveyor belt 220, the conveyor belt 220 moves, causing soil to be output from the open position of the hopper door 110. The distance between the hopper door 110 and the surface of the conveyor belt 220 controls the thickness of the soil covering.

[0033] Furthermore, to ensure the looseness of the soil during the covering operation, in some embodiments, such as... Figure 1and Figure 3 As shown, a mixing device is installed inside the silo 100. The tangential direction of the mixing device is the same as or opposite to the conveying direction of the conveying mechanism 200. When the tangential direction of the mixing device is the same as the conveying direction of the conveying mechanism 200, the mixing resistance of the mixing device is small, and the mixing device mixes the soil to prevent soil compaction in the silo 100 and maintain soil looseness. When the directions are opposite, the mixing effect of the mixing device is better and more thorough, which can further improve the looseness of the soil.

[0034] Specifically, the mixing device includes a mixing shaft 410, which is arranged parallel to the conveying surface of the conveying mechanism 200. Multiple mixing rods 420 are arranged along the axial direction of the mixing shaft 410. One end of the mixing shaft 410 extends into the discharge hopper 100 and connects to a second driving member 430, which drives the mixing shaft 410 to rotate around its axial direction. When the mixing shaft 410 rotates, the mixing rods 420 rotate with it, rotating circumferentially around the mixing shaft 410, thereby agitating the soil. Furthermore, the mixing rods 420 are L-shaped or Z-shaped, with multiple mixing rods 420 staggered on the outer circumferential surface of the mixing shaft 410. The shape of the mixing rods 420 increases the contact area between the rods and the soil, and the staggered arrangement of the mixing rods 420 allows for multi-angle and multi-directional contact with the soil within the hopper 100, thereby further improving the mixing effect and increasing the soil's looseness.

[0035] In some embodiments, such as Figure 4 As shown, a soil-spreading roller 500 is installed below the output end of the conveying mechanism 200. The soil-spreading roller 500 and the conveying mechanism 200 are driven by the same drive mechanism. The shared drive mechanism allows the soil-spreading roller 500 and the conveying mechanism 200 to share a single power system, which helps to simplify the structural design. Moreover, the conveying mechanism 200 can drive the soil-spreading roller 500 to rotate while conveying soil, and the soil-spreading roller 500 can break up the falling soil and prevent it from accumulating in one place.

[0036] Specifically, such as Figure 4 and Figure 5As shown, the conveying mechanism 200 comprises a frame 210 and a conveying belt 220, both ends of the frame 210 are provided with a driving conveying shaft 230 and a driven conveying shaft 240, the driving conveying shaft 230 and the driven conveying shaft 240 are connected through the conveying belt 220. The frame 210 is provided with a synchronous wheel 250, the synchronous wheel 250 is connected with the driven conveying shaft 240, and the soil roller 500 is connected with the synchronous wheel 250. Wherein, the driving conveying shaft 230 is connected with the third driving mechanism 260, the third driving mechanism 260 is a motor, and the third driving mechanism 260 and the driving conveying shaft 230, the driven conveying shaft 240 and the synchronous wheel 250, and the synchronous wheel 250 and the soil roller 500 are connected through chain transmission or belt transmission.

[0037] In some embodiments, the length direction of the soil roller 500 is provided with roller discs at both ends, and a roller shaft is arranged through the center of the two roller discs. A plurality of roller bars are connected between the two roller discs, the plurality of roller bars are arranged around the circumferential direction of the roller disc and gaps are left between the roller bars. The roller bars are arranged outside the circumferential direction of the roller shaft, and when the soil roller 500 rotates, the roller bars are in full contact with the falling soil to scatter the soil and prevent the soil from accumulating at the same place. The gaps between the roller bars are also beneficial to the falling of the soil and prevent the soil from accumulating on the soil roller 500. In addition, in other embodiments, the soil roller 500 comprises a roller body, and a plurality of roller grooves are arranged on the circumferential surface of the roller body, and the length direction of the roller grooves is parallel to the axial direction of the roller body. When the roller body rotates, the roller grooves are in full contact with the falling soil to scatter the soil. Moreover, under the condition that the roller body continuously rotates, the soil cannot accumulate on the roller body, and the centrifugal force generated by the rotation of the roller body throws the soil in the rotating direction, which is beneficial to scattering the soil.

[0038] It should be noted that, in some embodiments, a soil collecting hopper 600 is arranged directly below the soil roller 500, which can collect the soil scattered by the soil roller 500 to a specified position, and the soil collecting hopper 600 can to a certain extent reduce the soil splashing to other positions. The soil covering machine is also provided with a standby knob 380, in addition to automatic control, the operator can control the operation of each driving mechanism through the standby knob 380.
