[Conventional technology]

Treating straw with ammonia activates bacterial digestion, and ammonia itself It is also used as a material for protein synthesis, serves as a source of nutrients, and is effective as feed for cattle, etc. Although it has been known for a long time, efficient methods for collecting straw have been a bottleneck.

0003 However, with the spread of roll balers, it has become possible to collect straw in a labor-saving manner. Monia processing is now performed.

0004 Conventionally, in the above ammonia treatment, the collected straw is reduced to a desired size as shown in Figure 8. The straw block 1 is formed as a roll bale, compact bale, bulk pile, etc. It is wrapped and sealed with a synthetic resin film (hereinafter referred to as film) 2. In this, liquefied anhydride Liquefied ammonia connected to a monia cylinder 3 via a pressure-resistant flexible hose 4 Insert the pipe 5a of the injection injector 5 and inject liquefied ammonia. Ru.

[0005] The injector 5 has a pointed tip and is closed, and ammonia is spouted around it. A nozzle 5b to be ejected is drilled, and an injector is inserted into the rear of the nozzle. A handle 5c is provided to support this. Note that 6 is liquefied ammonia Display of strain gauge to know injection volume and variable setting of injection flow rate to predetermined amount A control panel that displays the orifice, etc., 7 is a valve, and 8 is a valve for injector 5. This is a flange connected to the flexible hose 4.

[0006] To inject liquefied ammonia using this device, hold the handle 5c and hold the film 2. pierce the injector 5 through the straw block 1. Then open valve 7. In this case, liquefied ammonia is blown into the straw block at a constant speed, and the amount of liquefied ammonia is blown into the straw block. When the desired amount is reached, close the valve 7, pull out the injector 5, and pierce it. The holes in the film are covered by gluing the film, etc., and the work is completed.

[0007]

[Problem that the idea aims to solve]

The amount of liquefied ammonia injected above is proportional to the amount of straw, so the amount of straw is If the number is large, it may take several 10 minutes. Also, at the beginning of the injection, the temperature of the straw is Because of the high temperature, the injected liquefied ammonia will either evaporate or be absorbed by the moisture in the straw. The heat generated during the process expands and a large amount of water temporarily erupts from the pierced hole, destroying the working environment. It gets extremely bad.

[0008] In addition, in order to improve the diffusion of ammonia and make it easier to react, straw is used in comparison. Since the target bulk density is small, the pierced injector can move easily and the liquefaction tank can be easily moved. While injecting Monia, the patient must be supported by the handle, which is a burdensome task. Ru.

[0009] In addition, the injected liquefied ammonia is light when it evaporates, so it migrates to the top and into the material. absorbed by water. Liquefied ammonia adheres to the straw and falls to the bottom, Depending on the amount of injection, the injection position, and the direction of the injection, it may not reach the lower part but may reach the surrounding area. It absorbs energy and gradually vaporizes. Therefore, the liquefier sprayed upward Monia stays relatively high up so it has poor contact with the straw.

0010 This invention was created in view of the above circumstances and suppresses the deterioration of the environment for workers. liquefaction, which is easy to support and allows efficient contact between ammonia and straw. The purpose is to provide an injector for ammonia injection.

[0011]

[0013] The tip of the pipe 11 is formed into a conical shape and is closed. The tip 12a of 12 is rounded.

[0014] On the outer peripheral surface of the conical portion 12, an upper edge 13a is formed at the tip 12 of the conical portion 12. Four plate-shaped plates that coincide with the outer circumferential surface near a and move away from the outer circumferential surface toward the rear. Fins 13 are integrally attached to the outer surface of the conical portion 12 at intervals of 90° in the circumferential direction. It is attached. The rear part of this fin 13 has an upper edge 13a with a rear edge at the rear so that it can be easily removed. The pipe 11 is inclined toward the outer peripheral surface of the pipe 11.

[0015] Further, in a predetermined length range from the vicinity of the rear part of the conical portion 12 of the pipe 11, Also, within a range of 120° or less from the central axis 11a of the pipe in the circumferential direction of the pipe, there is no liquid. A plurality of nozzles 14 are provided for spouting ammonia chloride.

[0016] Also, on the outer periphery of the pipe 11 at the rear of the area where the nozzle 14 is bored, , a flange 1 that is movable in the length direction of the pipe 11 and can be fixed to the pipe 11 5 is installed. A sponge 16 containing water is placed in front of this flange 15. installed.
