DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] REFERENCE Figures 1 to 7The utility model provides a kind of fungicide soil stirring device, including mobile car body 1 and fungicide supply tank 2, fungicide supply tank 2 is loaded with appropriate amount of fungicide made of fungus gray yellow penicillium CF3, mobile car body 1 is equipped with caterpillar walking structure, can be tractor agricultural machinery traction, mobile car body 1 is provided with at least two number of measuring cylinder 33, the middle position of mobile car body 1 is provided with the feeding part 3 for driving measuring cylinder 33 to receive and transport fungicide from fungicide supply tank 2 to planting pit, measuring cylinder 33 is driven in revolution and rotation to cause fungicide to be uniformly mixed, the rear position of mobile car body 1 is provided with the fusion part 4 for stirring fungicide and soil in planting pit, and the fusion part 4 includes the stirring piece 45 for wet stirring fungicide and soil.

[0028] Refer to Figure 1 With Figure 2 Fungicide supply tank 2 is fixedly arranged at the front side of mobile car body 1, and a feeder for quantitatively discharging fungicide to the measuring cylinder 33 is arranged on the fungicide supply tank 2, the feeder can be a screw conveyor or a pneumatic conveying device, for conveying 1 kg of fungicide to each measuring cylinder 33 at a time, and the key is quantification, to ensure the accuracy of the dosage of fungicide in each planting pit or unit area, to avoid waste or insufficient dosage. Preferably, a precision screw feeder with a servo motor is linked with the walking speed sensor or GPS positioning system of the mobile car body 1, to dynamically adjust the feeding speed according to the traveling speed and the preset unit dosage, to achieve the purpose of variable and accurate application.

[0029] Refer to Figure 4 With Figure 5 The upper and lower ends of the measuring cylinder 33 are both open, and a limiting flange is integrally arranged at the upper end opening position of the measuring cylinder 33, the measuring cylinder 33 has a funnel structure, and the upper end opening is intercepted by the limiting flange to prevent the leakage of fungicide under the action of centrifugal force during rotation, and to prevent the measuring cylinder 33 from falling off from the limiting hole position 32.

[0030] Refer to Figure 4 With Figure 5 The feeding part 3 includes a rotating platform 31 rotatably installed on the mobile car body 1, a servo motor for driving the rotating platform 31 to stepwise rotate is arranged on the mobile car body 1, the rotating platform 31 is provided with limiting hole positions 32 for rotatably sleeving the measuring cylinders 33, the number of limiting hole positions 32 is determined according to the number of measuring cylinders 33, and the limiting hole positions 32 are distributed equidistantly in the circumferential direction, and the design of multiple measuring cylinders 33 helps to realize the parallel operation of the processes of receiving, mixing and discharging, to improve the material preparation and circulation efficiency of the equipment. The driven gear 34 is fixedly sleeved on the measuring cylinder 33, the driving rack 35 engaged with the driven gear 34 is slidably installed on the rotating platform 31, the booster rod 36 is integrally connected to the outer end of the driving rack 35, and the crescent lug 37 corresponding to the booster rod 36 is fixedly installed on the mobile car body 1.

[0031] It is worth mentioning that when the rotating platform 31 revolves with the measuring cylinder 33, centrifugal force will be generated, which makes the driving rack 35 have a tendency to slide outward. When not in contact with the crescent block 37, the driving rack 35 is disengaged from the driven gear 34. When the booster rod 36 is in contact with the convex surface of a certain crescent block 37 with the revolving motion, the profile of the crescent block 37 generates an inward extrusion force on the booster rod 36, which overcomes the centrifugal force (or cooperates with the reset spring force) to force the driving rack 35 to slide inward and engage with the driven gear 34. With the continuation of the revolution, the continuous extrusion of the crescent block 37 forces the driving rack 35 to linearly displace, thereby driving the driven gear 34 and the measuring cylinder 33 fixed thereto to rotate, i.e. to revolve. By providing a reset spring for elastically supporting the driving rack 35 on the rotating platform 31, when the convex surface of the crescent block 37 slides away, the driving rack 35 moves outward to disengage under the reset spring or the weakened centrifugal force, and the revolution stops. Through purely mechanical means, the revolution is triggered at a specific stage of the revolving path (preferably for most of the travel from receiving to discharging), so that the fungicide in the measuring cylinder 33 is repeatedly thrown and turned in three-dimensional space, achieving the uniform mixing effect of bidirectional rotary motion, and without the need to configure a driving motor for each measuring cylinder 33, the structure is compact and reliable.

[0032] With reference to Figure 1 The number of crescent blocks 37 is at least two, and the crescent blocks 37 are distributed equidistantly in the circumferential direction. The inner wall surface of the crescent block 37 is a curved surface structure to press and drive the booster rod 36 that is rotating.

[0033] Four measuring cylinders 33 can be evenly arranged on the rotating platform 31. When the No. 1 measuring cylinder 33 is receiving at the A station, the No. 2 measuring cylinder 33 is being mixed by revolution and revolution at the B station, the No. 3 measuring cylinder 33 is waiting at the C station, and the No. 4 measuring cylinder 33 is discharging at the D station. The rotating platform 31 rotates 90° every step, i.e. completes a working cycle.

[0034] With reference to Figures 4 to 6, the feeding part 3 further comprises an opening and closing mechanism 38 for controlling the opening and closing of the lower end opening of the measuring cylinder 33, and a receiving table 39 corresponding to the lower end opening of the measuring cylinder 33 is fixedly arranged at the rear side of the moving vehicle body 1. The opening and closing mechanism 38 comprises a driving rotating shaft 381 rotatably arranged in the rotating platform 31; the rotating platform 31 is hollow at the vertical position, and a driving motor for driving the driving rotating shaft 381 to horizontally rotate is fixedly arranged in the rotating platform 31, and the driving motor is configured as a servo controller; the driving rotating shaft 381 is fixedly connected with a lifting telescopic rod 382, and the lifting telescopic rod 382 is fixedly arranged with a traction swing rod 383; the lifting telescopic rod 382 is preferably an automatic telescopic rod which can vertically extend and retract, so that the traction swing rod 383 can be adjusted in horizontal rotation and vertical lifting according to actual needs, and the lifting telescopic rod 382 automatically extends and retracts through the control system. The rotating platform 31 is provided with a guide long hole 384 facing the limiting hole 32, and the guide long hole 384 is provided with an elastic right-angle baffle 385 which is movably pulled by the traction swing rod 383 and corresponds to the lower end opening of the measuring cylinder 33. A long hole is preferably arranged in the free end of the traction swing rod 383, and the specific arrangement (such as length) of the long hole is matched with the specific stroke required for opening the bottom of the measuring cylinder 33, and the top end of the elastic right-angle baffle 385 is integrally connected with a traction bolt which can be movably sleeved in the long hole.

[0035] It is worth noting that in the initial state, the traction swing rod 383 is not in contact with the traction bolt, and in the receiving and mixing station, the elastic right-angle baffle 385 extends radially to below the lower end opening of the measuring cylinder 33 under the action of its own elastic force or auxiliary spring, thereby forming a blockage. When the measuring cylinder 33 containing the to-be-placed fungicide is rotated to align with the receiving table 39 (fixedly arranged at the rear side of the moving vehicle body 1), the traction swing rod 383 is horizontally rotated to the top end of the elastic right-angle baffle 385, the traction swing rod 383 is lowered through the lifting telescopic rod 382, and the top end of the elastic right-angle baffle 385 is in contact with the traction bolt, that is, limited by the side wall of the long hole, the driving motor drives the traction swing rod 383 to rotate on the horizontal plane, thereby pulling the elastic right-angle baffle 385 radially along the guide long hole 384 to open the lower opening of the measuring cylinder 33, and the mixed uniform fungicide is guided by the receiving table 39 under the action of gravity and accurately placed into the planting pit below. After the placement is completed, the lifting telescopic rod 382 is raised, the elastic right-angle baffle 385 is reset under the action of the elastic force, the lower end opening of the measuring cylinder 33 is re-blocked, and the next receiving cycle is prepared. The lower end opening of the measuring cylinder 33 is accurately opened and closed at the specified position, and the opening and closing action is coordinated with the stepping motion of the rotating platform 31. In this way, a single driving motor can drive multiple measuring cylinders 33 to store and place materials, thereby effectively reducing energy consumption, simplifying the layout of the mechanism, and reducing the overall volume of the mechanism.

[0036] Reference Figure 2 With Figure 6, the fusion part 4 further comprises a driving turntable 41 rotatably installed on the mobile vehicle body 1, and it is to be noted that the mobile vehicle body 1 is provided with a driver, preferably an electric motor, for driving the driving turntable 41 to rotate, and the driving turntable 41 is rotatably installed at the rear end position of the mobile vehicle body 1, and a reciprocating swing arm 42 is movably pulled by the driving turntable 41, and the reciprocating swing arm 42 is movably provided with a lifting frame 44 fixedly installed with a stirring piece 45, and the lifting frame 44 is fixedly installed with a water bag 46 for filling pure water and is provided with a high-pressure water pump, and the stirring piece 45 is internally hollow or is provided with a flow channel and is communicated with the water bag 46 through a corrugated hose and is provided with a plurality of high-pressure spray holes 47 on the side or bottom thereof, and the pure water (an adhesive can be added) in the water bag 46 is sprayed out from the high-pressure spray holes 47 in the form of mist or fine stream before or during stirring.

[0037] The wetted microbial agent is not easy to drift, and the loss and pollution to the environment are reduced.

[0038] The moisture helps the microbial agent particles to adhere to the soil particles and accelerates the initial fusion.

[0039] The moisture provides instant water for the survival of the microbial agent and improves the colonization activity thereof.

[0040] Referring to Figure 7 , the driving turntable 41 is provided with a traction connecting rod 43 rotatably connected with the reciprocating swing arm 42. The driving turntable 41 is continuously rotated, and the rotational motion is converted into the reciprocating swing of the reciprocating swing arm 42 through the traction connecting rod 43. The swing directly drives the stirring piece 45 to make a pendulum or fan-shaped reciprocating motion in the planting pit, and the just-placed microbial agent and soil are subjected to strong stirring. At the same time, the water can be sprayed after the stirring piece 45 is inserted into the soil, so that the stirring and wetting are realized at the same time, and the microbial agent, the moisture and the soil are fully and uniformly mixed into a wet granular structure, so that the best growth microenvironment for the microbial agent is created.

[0041] It is to be noted that the specific model and specification of the mobile vehicle body 1 and the microbial agent supply tank 2 need to be determined according to the actual specification of the device, and the specific selection calculation method adopts the existing technology in the art, and thus is not described in detail.

[0042] Based on the above mode, an automatic microbial agent soil stirring device integrating quantitative material taking, in-process premixing, accurate placement and on-site wetting is provided, and the core lies in that the conveying process of the microbial agent is converted into a mixing process, and a wet stirring environment is created, so that the operation quality and efficiency are improved.

[0045] Referring to Figure 1 With Figure 5 When one of the cylinders 33 rotates to the corresponding fungicide supply box 2, in this state, the elastic right-angle baffle 385 expands radially along the guide long hole 384 to block the lower end opening of the cylinder 33, and 1 kg of fungicide is put into the cylinder 33 through the feeder;

[0046] Referring to Figure 4 With Figure 5 The rotating platform 31 expands radially outward due to the centrifugal force generated in the rotating process, and when the boost rod 36 connected with the driving rack 35 is in contact with the crescent block 37, the driving rack 35 drives the driven gear 34 to rotate, thereby driving the cylinder 33 to rotate in the limiting hole 32, so that the fungicide rotates bidirectionally in the cylinder 33; the rotating platform 31 and the crescent block 37 drive the efficient premixing of the fungicide in the conveying process.

[0047] Referring to Figures 4 to 6 When the cylinder 33 rotates with the rotating platform 31 to the corresponding receiving table 39, the control lifting telescopic rod 382 drives the traction swing rod 383 to vertically move downward, and the traction bolt on the elastic right-angle baffle 385 is moved, the driving shaft 381 is controlled to rotate by the driving motor, so that the elastic right-angle baffle 385 moves radially along the guide long hole 384 to open the lower end opening of the cylinder 33, and the uniformly mixed fungicide in the cylinder 33 is discharged to the planting pit position through the receiving table 39; the step-by-step multi-station design realizes continuous operation, and the reciprocating stirring piece 45 with the wet spraying function realizes the in-situ deep and wet fusion of the fungicide and the soil.

[0048] Referring to Figure 2 , Figure 3 With Figure 7 The driving turntable 41 is controlled to rotate, and the water bag 46 is controlled to discharge an appropriate amount of pure water to the stirring piece 45, the driving turntable 41 drives the reciprocating swing arm 42 to swing back and forth through the traction connecting rod 43, and the wet stirring piece 45 drives the stirring of the fungicide splashed on the soil, thereby accelerating the uniform fusion of the fungicide and the soil.

[0049] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
