Description

Technical Field

[0001] The utility model relates to the field of soil passivator spreading, in particular to a cover-type solid passivator spreading device. Background Art

[0002] At present, in the passivation and remediation projects of heavy metal soil pollution in agricultural land, how to safely and evenly spread the passivator into the area to be repaired has always been a difficult point in the construction process of the remediation project. In addition to the passivation of heavy metals, the passivator of this type of remediation project is often accompanied by the function of adjusting the pH of agricultural land, so it often has strong alkalinity or acidity. The repair of heavy metal polluted agricultural land has the characteristics of precise material dosage, uniform material application, and the solid passivator itself is easy to agglomerate, resulting in the traditional construction process using: 1. Manual spreading, the disadvantage is that it can not ensure the accuracy of the passivator dosage, and it is also easy to cause artificial acid and alkali burns; 2. Spraying with traditional pesticide sprayers, the disadvantage is that the passivator particles are small, and the existing sprayers are specially designed for agricultural use, with large power and large wind force of the nozzle. If used in such projects, the passivator will inevitably drift.

[0003] According to the disclosed patent CN201921736635.2, a hood-type solid passivator spreading device includes a support frame, a base, a nylon shoulder strap, a mixing box, a mixing rod, a gasoline engine, a material pump, a spray pipe, a grounded hood-type nozzle and an air volume regulating valve. The utility model can evenly stir the passivation repair agent on site, achieve accurate and uniform application of the passivation agent, and ensure the safety of the construction personnel. The hood-type solid passivation agent sprayer has a simple structure, is easy to operate, and has a low cost. It has a good application value in various agricultural land heavy metal soil pollution passivation repair projects. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although the passivation repair agent is evenly stirred on site, the accurate and uniform application of the passivation agent is achieved, and the safety of the construction personnel is guaranteed. The hood-type solid passivation agent sprayer has a simple structure, is easy to operate, and has a low cost. It has a good application value in various agricultural land heavy metal soil pollution passivation repair projects. It solves the problem of using the following traditional construction process: 1. The disadvantage of manual application is that it can neither ensure the accuracy of the amount of passivator used nor easily cause artificial acid and alkali burns; second, the disadvantage of spraying with a traditional pesticide sprayer is that the passivator particles are small, and the existing sprayers are designed for agricultural use, with large power and large wind force from the nozzles. If used for such projects, the passivator will inevitably drift. However, during use, the traditional hood-type solid passivator spreading device uses a grounded hood-type nozzle to spread solid passivator on the ground. This spreading method only spreads the solid passivator within a small range, but the uniformity of the solid passivator within the range is not very high, which affects the effect of the solid passivator spreading. Moreover, when the solid passivator is output through the material pump, the material is prone to blockage in the pipeline, which affects the normal circulation of the solid passivator. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a hood-type solid passivator spreading device to solve the current traditional hood-type solid passivator spreading device, which adopts a grounded hood-type nozzle to spread solid passivator on the ground. This spreading method only spreads the solid passivator within a small range, but the spreading uniformity of the solid passivator within the range is not very high, which affects the effect of the solid passivator spreading, and when the solid passivator is output through a material pump, the material is prone to blockage in the pipeline, which affects the technical problem of the normal circulation of the solid passivator.

[0007] The spreading mechanism is passed through the outside of the rotary joint, and the cover body can be driven to rotate by the spreading mechanism, thereby increasing the range of the solid passivating agent and improving the effect of the solid passivating agent spreading. The spreading mechanism includes a first gear, the rotary joint is passed through the inside of the first gear, and the first gear is fixedly connected to the penetration position of the rotary joint;

[0008] A second gear is meshed with one side of the first gear, a first rotating rod is fixedly connected to the top of the second gear, a first motor shaft is fixedly connected to the top of the first rotating rod, a first motor is connected to the top of the first motor shaft, and a connecting pipe is connected to one side of the first motor by screws.

[0009] Preferably, the bottom of the rotary joint is fixedly connected to a discharge pipe, and the bottom of the discharge pipe is connected to a discharge cover.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model combines a rotary joint, a gear and a first motor. During the process of spreading the solid passivator, the first motor can be used to drive the first gear and the second gear to rotate, so that the rotary joint drives the discharge cover to rotate, thereby rotating and spreading the solid passivator, improving the uniformity of the solid passivator spreading, and solving the problem that the traditional cover-type solid passivator spreading device uses a grounded cover-type nozzle to spread the solid passivator on the ground. This spreading method only spreads the solid passivator within a small range, but the spreading uniformity of the solid passivator within the range is not very high, which affects the technical problem of the solid passivator spreading effect.
