Self-mixing agent spreading vehicle for farmland soil treatment

Abstract

The invention discloses a self-mixing agent spreading vehicle for farmland soil treatment. The vehicle comprises a vehicle plate; mud overturning rollers are rotatably fixed to the bottom of the vehicle plate, a plurality of mud overturning shovels are fixed to the circumferential surfaces of the mud overturning rollers, and cleaning rollers are arranged above the inner sides of the mud overturning rollers; the top surface of the vehicle plate is sequentially provided with a material storage cylinder, a blanking hopper and a water storage tank from left to right; the bottom of the material storage cylinder is fixed to the left top surface of the mud overturning rollers through vibrators, and a material guiding pipe is connected to the right side wall of the material storage cylinder; the blanking hopper and a blanking port are formed in the center of the top surface of the vehicle plate, an outer mixing cylinder and an inner stirring cylinder are arranged under the blanking port, the inner stirring cylinder is sleeved with the outer mixing cylinder, the bottom surface of the outer mixing cylinder is fixedly provided with a stirring motor, a motor shaft of the stirring motor is fixedly provided with a stirring rod, and a plurality of stirring baffles are fixed at the portion, in the inner stirring cylinder, of the rod wall of the stirring rod. According to the self-mixing agentspreading vehicle, through the outer mixing cylinder and the inner stirring cylinder, the agent spreading range is enlarged, and the situation can also be prevented that the waste is caused when agents are put aside for a long time and then oxidized and deteriorated.

Description

technical field [0001] The invention relates to the field of soil treatment equipment, in particular to a self-mixing sprayer for farmland soil treatment. Background technique [0002] In-situ chemical passivation is currently the most commonly used treatment method for heavy metal pollution in farmland soil. Its main content is to spread the soil conditioner in the soil, mix it evenly with the soil of the plow layer, and reduce the activity of heavy metals in the soil by means of chemical precipitation and adsorption, so as to achieve the purpose of restoration. The in-situ chemical passivation method operates It is simple and convenient, but there are still some difficulties in the operation process. The soil conditioner is often powdery particles, and the efficiency of manual spraying is low. Mechanical spraying often causes powdery agents to block the outlet of the agent, resulting in uneven spraying and poor spraying area. Minor problems. In addition, the sprayed chemi...

Its main content is to spread the soil conditioner in the soil, mix it evenly with the soil of the plow layer, and reduce the activity of heavy metals in the soil by means of chemical precipitation and adsorption, so as to achieve the purpose of restoration. The in-situ chemical passivation method operates It is simple and convenient, but there are still some difficulties in the operation process. The soil conditioner is often powdery particles, and the efficiency of manual spraying is low. Mechanical spraying often causes powdery agents to block the outlet of the agent, resulting in uneven spraying and poor spraying area. Minor problems. In addition, the sprayed chemicals are often scattered on the soil surface and cannot be mixed with the deeper soil, thereby reducing its passivation conditioning effect.

[0003] Therefore, in order to increase the feeding speed of powdered medicament particles and fully contact with the soil, water is often added as an auxiliary spraying solvent. Generally, water is added to mix the medicament before spraying, but this method is easy to use in the medicament. In the case of incomplete storage, the remaining agents cannot be preserved, and the agents are easily oxidized for a long time, losing the effect of treating the soil. Therefore, this configuration method is likely to cause a lot of waste of agents. Therefore, we need a method that can improve the spraying effect. Effective and can reduce the waste of medicine spraying device
