Description

A block type urban grass clipping treatment device

technical field

The invention relates to the technical field of grass cuttings, in particular to a block-making urban grass cuttings crushing and processing device.

Background technique

Lawns play an important role in my country's urban construction, improvement of living environment, and improvement of people's spiritual civilization. Turfgrass is used as urban greening grass, which is spread all over parks, residential areas, golf courses, football fields and other places, and its proportion in green spaces is generally higher than 70%. With the rapid development of urban landscaping, during the entire growing season of the lawn, a huge amount of grass clippings are trimmed almost every day. The large amount of grass clippings produced after lawn trimming are mostly mixed with urban domestic waste by lawn managers at this stage. Afterwards, they are transported together to the municipal garbage dump as garbage disposal. However, treating grass clippings as garbage not only occupies land and consumes financial resources, but also traditional treatment methods for grass clippings, such as burning and landfilling, will cause serious pollution to the environment and waste biological resources. In addition, the temperature is high in summer, and the untreated grass clippings will produce unpleasant smell, which is also a kind of pollution to the environment.

In view of this, the present invention is proposed.

Working principle of the present invention:

During operation, at first the box cover 2 is closed and the exhaust fan 4 is collecting grass clippings or when the box cover 2 is opened to directly collect grass clippings, the storage box 12 and the compacting box 20 can continue to work, and the blocking plate 15 is controlled by a switch to prevent The grass clippings that have not been processed enter the material storage box 12, and this plan will not be described in detail. The first filter screen 9 provided on the outer wall side of the collection box 1 is to prevent the grass clippings from flying out and collecting during the crushing and stirring process. Box 1, the dust sucked when collecting grass clippings is discharged from the sewage pipe 11. The second filter screen 17 and the third filter screen 24 arranged in the material storage box 12 are used to filter grass clippings with a length not greater than 4cm. The grass clippings in the material storage box 12 are discharged to the soil surface at a low speed by the third turbo exhaust fan 25. In order to facilitate the transportation and recycling of the bulk grass clippings after treatment, a part of the grass clippings in the material storage box 12 are continuously dried by the dryer 29. After processing for 20 minutes, add enzyme and bio-adhesive into the water tank 14 in a certain proportion through the control valve at the feeding funnel 13, and the mixed liquid is sprayed to the compaction box 20 at a constant speed by the timing jet pump 27, and is pressed in the steel mold 23 After the inside is mixed evenly with the grass clippings, the pressed steel plate 22 is turned downwards from the vertical direction to the horizontal direction through the action of the plate turning machine 30, and the pressed steel plate 22 is pressed down by the cylinder hydraulic press 18 to suppress the grass clippings. The protruding button 203 at the bottom of the mold 23 retracts inwardly, and the pinch plate 204 fixed on the protrusion 21 under the cooperation of the rotating shaft 201 and the spring 202, presses the steel mold 23 to open downwards, so that the block grass clippings after the preliminary treatment are automatically falls to the ground.

The present invention utilizes the open-close collection box 1 to flexibly collect grass clippings, and after the grass clippings are evenly broken to a length not greater than 4 cm in the collection box 1, the grass clippings can be directly discharged at a low speed by the third turbo exhaust fan 25 on the outer wall of the material storage box 12. , return to the soil surface of the lawn to decompose, return a large amount of nutrients in the grass clippings to the soil, avoid the excessively long grass clippings directly covering the lawn, form a hay layer and affect the quality of the lawn, which is conducive to improving the aeration of the soil at low cost, making the soil looser and more Use less fertilizer. It is also possible to add a certain proportion of enzymes and bio-adhesives to the crushed and dried grass clippings, then press the grass clippings downward through the pressing steel plate 22, and quickly make block grass bricks, which are formed by pressing the steel mold 23 Open down directly to recycle. The grass clippings are directly recycled from the compaction box 20 to make block grass bricks. The grass bricks can be used as landscape sketches on the spot to show the ecological low-carbon design concept, and the recycled block grass bricks can also be directly transported to ecological treatment as a whole. Station, the treated grass bricks can be recycled into precious resources such as expensive plant nutrient substrates and soil improvers. The invention not only turns grass clippings into treasures, creates new utilization value, but also reduces environmental pollution caused by disposal as garbage, has wide application prospect and is beneficial to popularization and application.

In this paper, specific examples are used to illustrate the inventive concept in detail, and the descriptions of the above embodiments are only used to help understand the core idea of the present invention. It should be pointed out that for those skilled in the art, any obvious modification, equivalent replacement or other improvement should be included in the protection scope of the present invention without departing from the inventive concept.
