Description

Spraying device for fixing sand planting material

Technical field

The invention relates to the technical field of desertification treatment, in particular to a spraying device for fixing sand-borne plant material.

Background technique

Land desertification is one of the most serious ecological and environmental problems in the world today. The latest data show that at present, the desertified land area of China is 2,623,700 square kilometers, and the desertified land area is 1,731,100 square kilometers, accounting for 27.33% and 18.03% of the total land area, respectively. In recent years, the ever-increasing sandstorms and the expansion of desertified land have made the ecological environment worse, and the living space of the people has been decreasing, which has caused great harm to the social and economic development.

Sand fixation is the main method of desert management. Chinese invention patent application CN200710085351.7 discloses a method for fixing sand by gypsum composite material, which firstly prepares a certain mass percentage of coagulant (main component: semi-aqueous or anhydrous gypsum, water absorbing agent, nutrient agent, Emptying agent, top dressing agent), and then coagulating these coagulants and mixing with the grass species to form a sand-fixing plant material. When using, first spray a layer of 1~2 cm thick of the above-mentioned sand-fixing plant material on the surface of the sand, and then sprinkle water to penetrate the sand-fixing composite layer. The raw materials used in this method are cheap and easy to obtain, and the preparation of the sand-fixing plant material is also very convenient, and the method of use is also very simple. It is only necessary to spray the mixed sand-fixing powdery material and then sprinkle it to make it condense, or to fix the sand. The slurry with the best ratio of material to water is sprayed directly onto the surface of the desert to be condensed. However, considering the vastness of the desert area and the harshness of the sandy environment, if large-scale sand-fixing operations are used manually, the efficiency of sand-fixing is difficult to increase, and the labor cost is high. Therefore, it is imperative to use a variety of delivery platforms in combination with the corresponding devices for large-scale operations of spraying and fixing plant materials.

detailed description

The technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the present invention, but not all embodiments. Based on the embodiments of the present invention, those skilled in the art before doing creative work All other embodiments obtained are considered to be within the scope of the invention.

As shown in FIG. 1 , the present embodiment provides a spraying device for fixing sand phytosanitary material. The spraying device 100 mainly comprises a hopper 1, a material conveying mechanism 2, a nozzle 3, an air compressor 4, and a driving motor 5.

Wherein, the material conveying mechanism 2 includes a tubular cavity 21 and a propulsion screw 22 disposed in the tubular cavity 21; the tubular cavity 21 is in communication with the hopper 1, and the propulsion screw 22 is used for The material entering the tubular cavity 21 of the hopper 1 is pressed to the end 21a of the tubular cavity 21. The nozzle 3 is connected to the end 21a of the tubular cavity 21 through a delivery pipe 6, and the nozzle 3 is also connected to the air compressor 4 through a gas pipe 7, which generates a high-pressure gas passage. The gas pipe 7 is sent to the nozzle 3, and the material entering the nozzle 3 from the feed pipe 6 is ejected. The drive motor 5 supplies a driving force to the material conveying mechanism 2 and the air compressor 4.

The hopper 1 may be detachably assembled to the tubular cavity 21 or may be integrally formed.

The working process of the spraying device 100 is as follows: the hopper 1 is mounted on the material conveying mechanism 2, the material to be sprayed is loaded into the hopper 1, and the driving motor 5 is started with the animal material conveying mechanism 2 and the air compressor 4, and the screw is pushed. 22 The material falling from the hopper 1 is transferred to the delivery pipe 6 and then transferred from the delivery pipe 6 to the nozzle 3. At the same time, the high-pressure gas compressed by the air compressor 4 is sent to the nozzle 3 through the gas pipe 7, and in the nozzle 3, the compressed high-pressure gas causes the pressure in the nozzle 3 to be greater than the external atmospheric pressure, and the material is sprayed to the nozzle 3. Externally, complete the jetting work.

The spraying device 100 as above can be applied to the field of desertification treatment, and is mainly applied to the spraying operation of chemical sand fixing and planting composite materials (including powder and slurry). There are two kinds of spraying methods: the first one is to spray the powder to fix the sand and plant the composite material, and then sprinkle the water to make the powder sand-fixing planting composite material coagulate; the other is to directly spray the slurry-like sand-fixing planting composite material, and the slurry is sprayed after being sprayed. The solidification of the sand-fixing composite material naturally condenses.

Further, in the present embodiment, the drive motor 5 drives the push screw 22 to rotate by a gear set 8. The material conveying mechanism 2 uses the propulsion screw 22, on the one hand, the sand-fixing material can be continuously stirred and mixed during the conveying process to ensure the uniformity and continuity of the material conveying. On the other hand, the use of the screw feeding rod can continuously advance the material. The squeezing force does not cause backflow of material due to excessive air pressure in the spout.

Further, as shown in FIG. 1, only one of the nozzles 3 is shown in this embodiment. In other embodiments, the number of the nozzles 3 may be plural, and each of the nozzles 3 is connected through a delivery pipe 6. Yu The end 21a of the tubular cavity 21, each of which is connected to the air compressor 4 via a gas pipe 7. The feed pipe 6 can be made of a high-strength rubber pipe.

A plurality of vibrating pieces 11 (two of which are exemplarily shown in Fig. 2) can be mounted on the inner wall of the hopper 1, and it is preferable that four to six vibrating pieces 11 can be mounted asymmetrically. The function of the vibrating piece 11 is to use the energy of the self-vibration to vibrate the nearby material particles, and to prevent the interruption of the feed caused by the blockage of the sand-fixing material in the middle when entering the material conveying mechanism 2. The hopper 1 is further provided with a power interface 12 for supplying power to the vibrating piece 11. The hopper 1 can be fixed to the material conveying mechanism 2 by a threaded fastener to ensure the stability of the installation of the hopper 1 and the sealing at the interface.

Further, the spray device 100 can be loaded on the mobile carrier platform 200 when in use. As shown in FIG. 3, the movable carrying platform 200 in this embodiment is a helicopter, and in other embodiments, a crawler tractor or automobile can also be used as the carrying platform 200. Referring to Figure 3, the entire spray device 100 is mounted in a helicopter nacelle that is powered by a helicopter power system for the drive motor and the vibrating plate. A reasonable number of nozzles 3 is determined based on the payload of the helicopter.

In summary, the spraying device for the sand-fixing plant material provided by the invention can realize the mechanized spraying and fixing of the plant material, so that the spraying of the material is more uniform, and the efficiency of the sand-fixing operation is also improved, and the labor cost is greatly saved.
