Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a soil disintegrating device for a soil disinfecting machine that suppresses the soil surface so that gas of the soil disinfecting chemical liquid injected into the soil does not leak.

[0002]

[Prior art]

 Conventionally, in a soil disinfecting machine configured by arranging a rotary, a soil disinfectant chemical injector, a leveling plate, and a pressure roll from the front part to the rear part of the machine having both wheels, the compression roll is fixed to the machine. It was rotatably mounted on an extending support arm.

[0003]

[Problems to be solved by the device]

 However, although the ground surface is pressed down with a compression roll so that the gas of the chemical liquid injected into the soil does not leak, the compression roll is rotated on the ground surface while being held at a certain height. However, if the squeezing roll is heavy or large to increase the squeezing effect, the weight balance of the aircraft will be lost. There were problems such as worsening and higher costs.

[0004]

[Means for Solving the Problems]

 The present invention has been devised so as to solve such problems and to be suitably implemented with a simple structure. Therefore, the rotary and soil disinfection chemical liquid injector from the front to the rear of the machine with both wheels. In a soil disinfecting machine configured by arranging a leveling plate and a squeeze roll, the front ends of both supporting rods obliquely mounted in the front-rear direction are pivoted to the machine so as to contact the upper parts of both cams fitted to the axles of both wheels. The compression roller is supported between the support rods, and the compression rollers are mounted between the rear ends of the support rods, and the rear portions of the support rods are elastically biased downward by springs.

[0005]

[Operation] Therefore, after the soil disinfecting chemical solution is injected into the soil cultivated by the rotary, the soil surface is leveled by the leveling plate, and thereafter, both support rods that are pressed against the soil surface side by the spring are applied. It is possible to vibrate the pressure suppression roll up and down while moving it up and down with a cam that rotates as the aircraft progresses, so that the chemical solution is effectively suppressed so that the chemical liquid does not leak gas by hitting the soil surface. be able to.

【Example】

 FIG. 1 is a side view of the soil disinfecting machine, partially broken away, showing a lower part in the forward direction of the machine A equipped with a mission case 9, both wheels 1, 1, an engine 10, a handle 11 and the like. A rotary working machine B having a rotary 2 is connected to the rotary work machine B, and an injection blade 3a and a chemical solution pipe 3b, which are chemical solution injectors 3 for soil disinfection, are vertically provided at the center of the rear of the rotary 2 in the lateral width direction. A pump portion 3c communicating with the chemical liquid pipe 3b is installed on the upper portion 12, and between the wheels 1 and 1 on the rear side of the chemical liquid injector 3, both supports extending from the upper portion of the rotary cover 12 are provided. The ground leveling plate 4 supported by the rods 13 and 13 is arranged, and the ground leveling plate 4 has a front height in the front-rear direction and a horizontal direction as shown in FIGS. Is configured to have a waveform.

A compression roll 5 is mounted behind the leveling plate 4, but cams 6 are fitted on the axles 1a, 1a of the wheels 1, 1 respectively, and the cams 6 are placed above the cams 6, 6 respectively. The compression roll 5 is rotatably mounted between the rear ends of the support rods 7 and 7 that are obliquely provided in the front-rear direction so as to contact the front end of the support rods 7 and 7. The upper and lower brackets 14 and 14 of the machine B are rotatably supported by the brackets 14 and 14, respectively, and the supporting rods 16 and 16 are extended above the supporting plate 15 mounted between the rear portions of the supporting rods 7 and 7, The upper portions of the support rods 16 and 16 are loosely fitted to a support frame plate 17 installed below the engine base 10a on which the engine 10 is mounted, and the compression rolls 5 are pressed downward to the support rods 16 and 16. The compression type springs 8 and 8 are fitted and configured.

Therefore, when the soil is cultivated by the rotary 2 while advancing the machine body in the direction of arrow A, and thereafter the chemical liquid is injected into the soil by the chemical liquid injecting machine 3, the injecting blade 3a submerges in the soil, thereby causing the soil in FIG. As shown in Fig. 3, the vertical groove 18 will be created, and then the soil surface will be leveled by the leveling plate 4 so that the upper side of the vertical groove 18 is blocked. As shown in the figure, the soil surface is leveled by the corrugated ground plate 4, and thereafter, the support rods 7 and 7 that are elastically pressed to the soil surface side by the springs 8 and 8 are connected to the wheels 1 and 2. It is possible to vibrate the compression roll 5 up and down as shown by the arrow B while moving it up and down by the cams 6 and 6 that rotate together with the 1 and 1, so that the wavy soil surface is hit. Liquid medicine It can be effectively suppressed so that it does not leak.

[0009]

[Effect of device]

 As described above, the present invention applies the soil disinfecting chemical solution to the soil cultivated by the rotary 2 and then lands the soil surface by the soil grading plate 4, and thereafter, the spring 8 elastically presses the soil surface to the soil surface side. It is possible to vibrate the compression roll 5 up and down while vertically moving the two supporting rods 7 and 7 that are being driven by the cam 6 that rotates together with the wheels 1 and 1, and the leveling plate 4 is used to level By hitting the soil surface, it is possible to effectively suppress the gas of the chemical liquid in the soil from leaking, which makes it possible to effectively perform soil disinfection work with a simple structure. It has the features that can be implemented.
