Description

[Detailed description of the device]

[0001]

[Industrial field of application] The present invention relates to a mixing machine for onion soil, fertilizer and the like.

[0002]

2. Description of the Related Art For example, an onion-only culture medium uses a culture medium mixed with a coagulant for the purpose of improving the water-holding property of the soil because the seeds and seedlings of the onion do not favor drying.

[0003] Conventionally, when mixing a dedicated soil for onions, a coagulant is mixed into a fixed amount of soil to form a soil, and a prescribed amount of water is sprinkled evenly on the soil with a watering can, for example, in actual development Sho 60-151531.
It was used in a pot for sowing or after being mixed with a mixer known in Japanese Patent Publication No. 1993, etc., or as a soil for a seedling box.

[0004]

[Problems to be Solved by the Invention] In the prior art,
The amount of water required when mixing the soil containing the coagulant is, for example, 20 water for 100 kg of the soil to be treated, and this amount of water must be stirred and mixed while evenly spraying the water on the stirring surface with a watering can. However, it was inferior in workability. An object of the present invention is to solve the above problems and to provide a mixer in which a required amount of water is evenly and uniformly sprayed on a stirring surface with stirring, and the structure is simple and workability is improved.

[0005]

According to the present invention, a stirring shaft is erected at the center of a mixer cylinder, and stirring blades connected to the stirring shaft via an arm rod are provided rotatably in the mixer cylinder. In such a mixer, a liquid tank is integrally provided on the arm rod, and a small hole is provided in a lower portion of a side surface of the liquid tank.

[0006]

[Function] When the soil and water are stirred and mixed, water is evenly sprayed on the stirring surface with stirring through a small hole for spraying water on the lower side surface of the liquid tank integrally attached to the arm rod to which the stirring blade is connected, The soil and the water are stirred and mixed.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3 show a first embodiment of the present invention, in which 1 is a mixer, and a stirring shaft 4 connected by a motor 3 or the like is erected at the center of a mixer cylinder 2. 5
Is a plurality of arm rods connected to the stirring shaft 4, and the arm rods 5
A stirring blade 6 is provided at the lower end of each of the. 7
Is a cylindrical liquid tank made of metal or synthetic resin and having an open top surface. A small hole 8 for watering is provided in the lower portion of the side surface of the liquid tank 7. The small holes 8 for water sprinkling are arranged in a vertical row in the lower part of the side surface of the cylindrical liquid tank 7 in which the diameters of the small holes for water sprinkling are smaller than those in the lower stage, those in the middle stage are those of medium diameter, and those in the upper stage are of large diameter. The small holes for water sprinkling of the same arrangement are also provided on the opposite surfaces of the liquid tank 7. Reference numeral 9 is an elastic curved portion that locks the liquid tank 7 on the arm rod 5. The elastic bending portion 9 is disposed on the bottom surface of the liquid tank 7 in a shape corresponding to the position of the arm rod 5 so that the liquid tank 7 is located above the stirring shaft 4, and the elastic bending portion 9 is attached to the arm rod 5. The liquid tank 7 is locked to the arm rod 5 by push-fitting. Reference numeral 10 is a water level gauge in which the scale is provided on the inner surface of the liquid tank 7 at fixed intervals such as 5 intervals.

Next, the operation of the above configuration will be described.
The onion-only soil is mixed with the coagulant in the mixer body 2 of the mixer 1 and the required amount of treatment is added. An appropriate amount of water is checked into the liquid tank 7 with the water level gauge 10 and poured into the liquid soil. Then, the motor 3 that drives the stirring shaft 4 is rotated. Along with the rotation of the stirring shaft 4, the soil is stirred by the stirring blades 6 and the liquid tank 7 that is locked to the arm rod 5 also rotates, and a small hole 8 for watering is provided in the lower part of the side surface of the liquid tank 7. Due to the centrifugal force, the water stored in the liquid tank 7 is sprayed. By making the diameter of the water sprinkling small holes 8 provided in the lower part of the side surface of the liquid tank 7 different, the water sprinkled from the water spraying small holes 8 of the lower stage having a small diameter will be in the vicinity of the liquid tank 7. In addition, the water sprinkled from the medium diameter of the middle stage is dispersed in the middle of the stirring surface, and the water from the large diameter of the upper stage is dispersed in the vicinity of the edge of the mixer barrel 2. The surface is evenly and evenly sprinkled, and the water and soil are well mixed.

Further, since the liquid tank 7 is detachably provided, when the soil other than the onion-only soil is mixed with fertilizer or soil conditioner, the liquid tank 7 can be detached for work. It is also possible to prevent damage or deformation of the liquid tank 7 due to contact with a scoop or the like at the time of charging.

As described above, the liquid tank 7 is locked by pushing the elastic curved portion 9 disposed on the bottom surface of the tank into the arm rod 5 and fitting the elastic curved portion 9 to secure the amount of water required for the soil. Water can be injected into the liquid tank 7 while confirming with the water level gauge 10, and the stirring shaft 4 is rotated to stir the soil with the stirring blades 6 and the water sprinkling small hole 8 provided at the lower side surface of the liquid tank 7 Due to the centrifugal force, the water is evenly and evenly distributed on the stirring surface, so that it is well stirred and mixed with the soil, and when it is unnecessary, the liquid tank 7 can be removed and other work can be performed, thereby improving workability.

4 and 5 show a second embodiment of the present invention. The same parts as those of the first embodiment are designated by the same reference numerals and their detailed description will be omitted. In the second embodiment, the arm rod 5
The boss 5A has a receiving projection 11 formed in a tapered shape, while the bottom of the liquid tank 7 has a locking portion for locking the receiving projection 11.
Twelve are provided. Therefore, when the liquid tank 7 is attached to the stirring shaft 4 side, the liquid tank 7 is attached to the boss 5A,
By placing it on the arm rod 5 and rotating it horizontally,
The locking portion 12 is locked to the receiving projection 11 so that the liquid tank 7 can be fixed.

The present invention is not limited to the above-described embodiment, and for example, the liquid tank may be attached by welding or screwing and fixing it directly to the arm rod instead of pushing in the elastic bending portion. Also, the small holes for water sprinkling provided at the lower part of the side surface of the liquid tank can be increased or decreased depending on the capacity of the mixer, the number of small holes can be increased or decreased at one position, and the diameter of the small holes can be changed. Various modifications are possible.
