Description

A spray height adjustable driving type sprayer which can control the spray height of the medicine

The present invention relates to a traveling drug spreader that can adjust the spraying height of the drug, and more particularly, to spray the drug by the blowing force of the blower fan is installed in the main body of the vehicle traveling by the engine driven by the engine By installing the auxiliary spraying device that can adjust the height at the top of the main spraying device and rotates in the vertical and horizontal direction to the ground, it is possible to easily spray the nutrients or insecticides according to the height of the fruit tree. In the case of a stepped field where the traveling drug spreader is difficult to directly enter, the traveling drug spreader that can adjust the spraying height of the drug that can be uniformly sprayed on both the high and low lands by using the main spraying device and the auxiliary spraying device. It is about.

In the case of spraying chemicals such as pesticides or water fertilizers on fruit trees, a conventional spraying device is installed at the end of the hose connected to the medicine container, and the sprayer moves the area where the chemical spraying is required while the sprayer carries the medicine container. In general, in this case, there was a problem that the work efficiency is poor because it is sprayed by one spraying device.

In addition, the method of spraying while the sprayer moves directly is difficult to spread in a large area as soon as the pest spreads again in the non-spreading area, and the spraying effect is greatly reduced. There was also a problem that the sprayers are exposed to the spraying liquid.

In order to solve this problem, a traveling spraying device has been recently developed in which a drug sprayer is installed at the tip of a slow transporter equipped with a caterpillar, and a blower fan is installed in the drug sprayer to spray the drug by the blowing force of the blower fan. .

However, in the case of the traveling type spraying device, since the blowing fan deflects the wind sucked from the front in a perpendicular direction and sends it in the direction of the spray nozzle, the blowing force is weak and the chemical feeding distance sprayed from the spray nozzle is 2 to 3 m. The short, tall fruit tree was inconvenient to prevent the chemicals from reaching the top, and it was inconvenient to control it.In order to make up for this, a large-scale blower was required. However, a large-sized blower requires a high-powered engine. Considering the structure of the present invention, the blower fan driving engine and the transporter transport engine have to be installed separately.

Therefore, in order to solve the problems of the prior art, the applicant of the present invention installs the drug sprayer on the front end of the undercarriage of the slow transporter equipped with a caterpillar on the bottom, but the engine power of the transporter moving at a walking speed in the drug sprayer blowing chamber. The drug spreader provided with a blower made of a sirocco fan rotating at a high speed was developed in detail.

In the case of the drug spreader disclosed in the following [Document 1], since the air sucked from the front of the blower chamber can be directly blown in the spraying direction of the sprayer of the drug sprayer installed on the outer periphery of the blower chamber because of the characteristics of the sirocco fan, It has the advantage of long distance spraying up to 5 ~ 8m under the power of wind supplied from the sirocco fan.

However, in the case of the drug spreader according to the following [Document 1], because the ventilation chamber is installed low, the chemical sprayed by the wind supplied from the sirocco fan is scattered in all directions by the wind in the air, so it is normal for the tall fruit tree. There was a problem that the drug can not be sprayed correctly.

At this time, the auxiliary spreading device 70 is as narrow as possible (or within the limit that the second pharmaceutical feed pipe (9b) can be accommodated therein to minimize the catch of the fruit tree, fruit, etc. when running the carrier body 1) Diameter).

In addition, in the detailed description and claims of the present invention, the term "horizontal to the ground" means a case in which the surface is laid down in the direction of the ground with a certain angle range as well as completely horizontal. Direction 'is meant to be erected in the upward direction with a certain angle range as well as completely vertical.

Meanwhile, as shown in FIGS. 6 and 7, the outside flowed in the direction of the rotation shaft 3a of the blower fan 3 through the inlet 20c by the rotation of the blower fan 3 located in the center of the blower chamber 20b. Air expands radially and exits through the outer circumferential surface of the blowing chamber 20b.

At this time, the blowing chamber 20b is provided with a blowing guide vane 20d to guide the size and direction of the blowing at a predetermined interval in the circumferential direction, the blowing guide vane 20d is the first in accordance with the installation position The width between the panel 23a and the second panel 23b may be set differently.

That is, in the present embodiment, as shown in Fig. 4, when the blower fan 3 rotates counterclockwise when the blower chamber 20b is viewed from the front side, the blower fan 3 rotates counterclockwise. The width of the installed blowing guide vane 20d is made larger.

On the contrary, if the blower fan 3 rotates clockwise when the blower chamber 20b is viewed from the front, the blower induction blade 20d having the width of the blower guide blade 20d installed on the right side of the center part is installed on the left side. It is formed larger than the width of 20d.

In the embodiment of the present invention, in the case of the main spraying device 2, the lower surface of the spreader main body 20 is connected to the lower portions of the first and second panels 23a and 23b so that the air outlet does not exist vertically downward. Therefore, when the rotary blades of the blower fan 3 passes vertically downward, the air continues to be compressed, and the first compressed air flows out at the same time when moving downward from the bottom.

For this reason, when the blowing fan 3 rotates counterclockwise as in the present embodiment, the amount of air that escapes to the right outer peripheral surface of the blowing chamber 20b is greater than the amount of air that escapes to the left outer peripheral surface. There is a problem that the amount of air exiting the blower chamber 20b becomes more symmetrical to each other, the width of the air induction blade 20d installed on the left and the right side as in the present invention set differently In this case, it is possible to uniformly adjust the uneven blowing amount in the left and right directions generated according to the rotation direction of the blowing fan 3.

In addition, in order to finely adjust the blowing amount, the long hole 50a is drilled in the longitudinal direction of the coupling piece 20e which is bent from the blowing guide vane 20d and coupled to one side of the spreader main body 20, and is fastened. It may be configured to be fixed to the sprayer body 20 while moving the position of the blowing guide blade 20d through the long hole (50a) using the sphere (40).

At this time, the blowing guide vane 20d moves in the center direction of the spreader main body 20 to fix it, and the blowing amount is increased, and when it is fixed away from the center direction, the blowing amount can be adjusted to be smaller. The wind sent from the) can be uniformly adjusted by adjusting the width of the blowing guide vane 20d and the installation position in the blowing chamber 20b.

On the other hand, although the blowing guide vane 20d may be made of a flat plate, in this case, since the wind from the outer circumferential surface of the blowing chamber 20b is transmitted to the fruit tree in a straight line, the medicine is applied to the leaves or fruits of the fruit directly receiving the wind. While it can be sufficiently sprayed, the leaves or berries that are hidden after being unable to receive the wind can cause a problem that the spraying of the drug is relatively insufficient.

Therefore, in order to solve this problem, in the present invention, as shown in FIGS. 6 to 8, the shape of the blowing guide vane 20d is spirally twisted along the length direction in which the wind is sent. In this configuration, the wind discharged through the channel formed by each blowing guide vane 20d from the outer circumferential surface of the blower chamber 20b exhibits a spiral whirlwind shape.

As such, when the air is blown in the form of a spiral whirlwind, the blowing distance is further increased by the blowing guide vane simply by a flat plate by the same principle that the distance of the rotating body is relatively longer than that of the non-rotating body. You can get it.

In addition, when the ventilation is made in the form of a spiral whirlwind, the leaves of the fruit or the like are not simply pushed back by the wind, but they are pushed in the wind and have some rotational movement along the wind direction (that is, the spiral direction). As a result, the medicine is effectively sprayed on the leaves or berries covered behind.

In addition, the blowing chamber 20b is transferred to the medicine by a hydraulic pump (not shown) through the medicine delivery pipe (9a, 9b) connected to the medicine supply container (9) in which the medicine is stored, the medicine delivery pipe (9a, At the end of 9b), the injection nozzles 4a and 4b are coupled to be disassembled and assembled by the bolt fastening method, and the injection nozzles 4a and 4b may be configured in one or a pair according to the spraying amount of the chemicals.

In addition, the injection nozzles (4a, 4b) are provided with a valve function at the same time as the chemical spray is made by the rotation or the chemical spray is blocked so that in the case of the injection nozzles (4a, 4b) installed in a direction that does not need the chemical spray Local spraying of the drug may be blocked by manipulation of the sprayer.

In addition, the first spray nozzle (4a) is located at the outer end of the blowing chamber (20b) to prevent the pesticide sprayed from the first spray nozzle (4a) to adhere to the inner wall surface of the blowing chamber (20b). desirable.

Referring to the operating state of the drug spreader according to the present invention configured as described above are as follows. According to the present invention, the main spray device 2 is provided at the tip of the vehicle target plate 1b of the transporter body 1, which is equipped with a caterpillar 1a and moves at a walking speed, and the blower chamber of the main spray device 2 20b) is provided with a blower fan 3 driven by the power of a 20-25 horsepower engine mounted on the carrier body 1, and rotates the blower fan at a speed of 1200 to 2500 rpm to suck in from the front of the carrier body 1; One wind is sent out in the installation direction of the first spray nozzle 4a.

Therefore, since the wind generated in the blowing fan 3 can be used for the transport of the medicine as it is without changing the direction, the amount of air flows and the chemical sprayed from the first spray nozzle 4a causes the wind of the blowing fan 3 to flow. It has the advantage that it can be sprayed to a distance of 5 to 8m, and when not spraying the drug, separate and load the main spraying device (2) from the vehicle body plate (1b) attached plate body (1c) of the carrier body (1) Since it can be used to transport agricultural products or agricultural materials by mounting a sieve spray can be effectively used and used.

In addition, the traveling drug spreader according to the present invention is installed on the carrier body running by the engine is possible to adjust the height on the top of the main spraying device to spray the drug radially by the blowing force of the blowing fan driven by the engine. If the sprayer operates only the main sprayer according to the height of the fruit, or only the auxiliary sprayer, or the main sprayer by installing the auxiliary sprayer so that it can rotate in the direction perpendicular to the ground and horizontally. Since the spraying operation can be performed by selecting any one of operating the auxiliary spraying device, there is an advantage in that the nutrient or insecticide can be efficiently sprayed according to the height of the fruit.

In addition, the traveling drug spreader that can adjust the spraying height of the drug according to the present invention, because the auxiliary spraying device can be rotated in a direction perpendicular to the ground and the horizontal direction is not the height of the fruit tree need to adjust the spraying height If there is not there is an advantage that can be prevented to damage the branches or fruit of the fruit tree with a low height by the auxiliary spraying device when running the drug spreader by rotating the auxiliary spraying device in a horizontal direction with the ground.

In addition, the traveling drug spreader that can adjust the spraying height of the drug according to the present invention effectively in both the highland and lowlands fruit trees even in the stepped field where the height of the two sides of the farm can run the traveling drug spreader effectively Spraying has the advantage of being possible, which is shown in FIG.

That is, in the case of the terraced field as shown in Fig. 9, the driving drug sprayer is difficult to directly enter the hills of the highlands, so the driving drug sprayer according to the prior art is effectively sprayed on the fruit trees located in the hills of the highlands. There was a problem.

However, in the case of the traveling drug spreader according to the present invention, as shown in Figure 9, the auxiliary spraying device 70 in the high ground on the left side in the state in the state in which the height is adjusted high by rotating the auxiliary spraying device 70 in the vertical direction. The drug is sprayed using a) and the drug is sprayed on the lowland on the right side using the main spraying device 2 so that the drug can be uniformly sprayed on both the highlands and the fruit trees of the lowland.
