Abstract

The utility model provides a granule is spray-seeding and is used spray gun, take place the pipe including group granule agent pipe, matrix pipe, rifle head, conveyer pipe, granule, the granule takes place the mouth of pipe and matrix pipe threaded connection of pipe, the granule takes place the top of pipe and has seted up feed inlet and granule agent pipe threaded connection, another mouth of pipe of group granule agent pipe and the mouth of pipe threaded connection of conveyer pipe, another mouth of pipe and rifle head threaded connection of conveyer pipe. The utility model discloses group's granule agent is carried to granule emergence intraduct through the pellet pump and is mixed with the matrix, because the high velocity of flow of group's granule agent and matrix, intensive mixing in the twinkling of an eye in the granule emergence pipe, in addition, the toper structure of rifle head makes the discharge gate department pressure of rifle head increase, and the material velocity of flow increases, can improve the journey of spraying gun, improves the efficiency of spouting, and simple structure, and the cost of manufacture is low, operation and easy maintenance, and the granule is effectual, spouts the journey and spouts efficiently.

Description

Spray gun for granule spray seeding

Technical Field

The utility model relates to a granule technique field of spouting, specifically a granule is spray gun for spouting.

Background

At present, the following two types of common spray guns are mainly used for granule spraying: a spray gun structure is that the granule conveying pipe is directly connected with a material injection pipe, when the pressure in the conveying pipe is greater than the pressure in the injection pipe, the granule in the conveying pipe can enter an injection channel, although the granule can be conveyed, two laminar flows cannot be formed in the channel due to the fact that a mixing space cannot be formed, the laminar flows cannot be mixed, the material and the granule are mixed unevenly, the injection effect is poor, when the pressure of the injection pipe is greater than that of the conveying pipe, the granule in the conveying pipe cannot enter the material injection pipe under the action of pressure, so that the material flows back to the conveying pipe, the conveying pipe is damaged, the blockage is formed, and the injection efficiency and the process are influenced; in order to solve the problems, the other spray gun is structurally improved, and the structure of the spray gun is as follows: the material injection pipe feed inlet diameter is greater than injection pipe diameter injection pipe middle part diameter, injection pipe middle part diameter is greater than the nozzle again, be equipped with the ring channel in the injection pipe outside, get into injection pipe lake from the ring channel all around as group's granule, form a plurality of group's granule flows with the material, though can reach the purpose of mixing, but this kind of granule flows still can not be fine and the material mixes, and when injection pipe internal pressure is greater than the conveyer pipe pressure, cause the granule can't get into the material passageway, the phenomenon of material to the interior refluence of conveyer pipe also can take place simultaneously, cause the damage to the conveyer pipe, form and block up.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a granule is spray-seeding and is used spray gun to solve the problem that exists among the above-mentioned background art.

The technical scheme of the utility model is realized like this:

the utility model provides a granule is spray-seeding and is used spray gun, includes granule agent pipe, matrix pipe, rifle head, conveyer pipe, granule generating tube, the mouth of pipe and the matrix pipe threaded connection of granule generating tube, the top of granule generating tube is seted up the feed inlet and is managed threaded connection with the granule agent, another mouth of pipe and the mouth of pipe threaded connection of conveyer pipe of granule agent pipe, another mouth of pipe and rifle head threaded connection of conveyer pipe.

Further, a ball valve is arranged on the substrate pipe.

Further, a ball valve is arranged on the granulating agent pipe.

Further, the gun head is conical, the diameter of the feeding hole is small, the diameter of the discharging hole is small, and a movable and detachable conical lining is arranged inside the gun head.

Furthermore, the inside of the pellet generating tube is provided with a wear-resistant lining, and the outside of the pellet generating tube is sleeved with a movable interface for connecting a hanging strip, so that spray-seeding personnel can hang the spray gun conveniently.

The utility model has the advantages that:

the utility model discloses group's granule agent is carried to granule emergence intraduct through the pellet pump and is mixed with the matrix, because the high velocity of flow of group's granule agent and matrix, intensive mixing in the twinkling of an eye in the granule emergence pipe, in addition, the toper structure of rifle head makes the discharge gate department pressure of rifle head increase, and the material velocity of flow increases, can improve the spray stroke of spray gun, improves the efficiency of spouting.

The utility model discloses be screw thread swing joint between each structure of spray gun, easy to assemble or dismantle, easily maintenance, operation convenient to use, and all be equipped with the ball valve on the matrix pipe of connection and the granule agent pipeline, can control the flow of matrix and granule agent, convenient to use.

The utility model discloses simple structure, the cost of manufacture is low, operation and easy maintenance, and the granule is effectual, spouts journey and spray-seeding efficiently.
