Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mixer for uniformly mixing an appropriate amount of fertilizer and / or chemicals into ground soil for raising seedlings, ground soil used as cover soil, for example. .

[Prior art and its problems] Conventionally, as a means for uniformly mixing an appropriate amount of fertilizer and / or chemicals with ground soil for raising seedlings, ground soil used as covering soil, fertilizer is used for ground soil contained in a container. The chemicals were added and the crushed soil was manually stirred to make both hands uniform. In such means, a lot of human power is required when the seedling preparation period is busy, and a lot of time is required, and there is a disadvantage that the compounding ratio of the both varies, which affects the seedling raising. is there.

In order to solve such technical problems, the applicant of the present invention has
We proposed a mixing machine as Japanese Patent Application No. Sho 63-49192, but this mixing machine uses a rotary stirring cylinder of a relatively large diameter, so the mixing machine itself becomes taller, and it is used to fill crushed soil, fertilizers, chemicals, etc. There are still problems such as obstacles and instability due to high center of gravity.

The purpose of the present invention is to mix crushed soil, fertilizer, chemicals, etc., and to automatically and continuously mix them, greatly shortening the time and saving labor.
It is intended to provide an inexpensive mixer that can be made compact as a whole.

[Means for Solving the Problems] In the configuration of the present invention for solving the problems of the prior art, a screw transfer body 8 in a substantially horizontal posture is mounted on the lower bottom of the hopper 7 for crushed soil provided on the machine frame, and On the downstream side of the conveyance of the screw transfer body 8, a screw transfer body 8b having a large diameter is provided coaxially therewith.
Are installed in series, and in the machine frame above the large-diameter screw transfer body 8b, there is a transfer direction opposite to the transfer direction of the screw transfer bodies 8 and 8b, and a transfer discharge mechanism with a small transfer amount is also provided. A hopper 15 for fertilizers, chemicals, etc. mounted on a shaft is mounted, and the delivery part of the transport and discharge mechanism and the midway part of the screw transfer body 8 are communicated with each other through a fall channel 17 in a substantially vertical posture.

[Embodiment] Next, details of an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a vertical side view, FIG. 2 is a cross-sectional view taken along the line BB of FIG. 1, and FIG. 3 is a front view of the same screw transfer body.

Reference numeral 1 denotes a machine frame, on both sides of the front end portion of the machine frame 1, leg rods 3 which pivotally support a rolling wheel 2 are provided at the lower end, and on both sides of the rear end portion of the machine frame 1, expansion and contraction are performed. A possible leg rod 4 is provided so that the front and rear axis of the machine frame 1 can be inclined downward or horizontal with respect to the ground by the expansion and contraction action of the leg rod 4. Reference numeral 5 in the figure is a cylinder rod for fitting the leg rod 4,
6 is a tightening bolt.

As shown in FIG. 2, an auxiliary hopper 7b, which has a U-shaped cross section at the bottom and has a horizontal transport cylinder 7a and which holds the crushed soil, is detachably attached to the rear portion of the machine frame 1 as shown in FIG. A volume hopper 7 is mounted. A screw transfer body 8 having a large transfer amount is mounted on the transfer cylinder portion 7a of the hopper 7 over the entire length thereof, and the diameter of the screw transfer body 8 and the diameter of the transfer cylinder portion 7a are equal to each other. By adapting the circular hole 9 provided on the front wall of the hopper 7 to the diameter of the screw transfer body 8, the crushed soil in the hopper 7 can be scraped by the circular hole 9 and a certain amount of crushed soil can be obtained. Are transported. Further, a pulley 10 is provided at the rear end portion 8a of the screw transfer body 8,
A base plate bridged between the pulley 10 and the left and right cylindrical rods 5
A pulley 13 of a motor 12 mounted on 11 is connected by a belt 14 so that the screw transfer body 8 is rotationally driven.

Reference numeral 15 is a small-volume hopper provided on the upper side of the machine frame 1, and the hopper 15 contains fertilizer and / or medicine. Then, a screw transfer body 16 with a small transfer amount is provided in a substantially horizontal posture on the lower bottom of the hopper 15, and the contents are transferred in a direction opposite to the screw transfer body 8 transfer direction. The delivery end of the body 16 and the midway portion of the screw transfer body 8 are provided with a drop flow path in a substantially vertical posture.
A small amount of fertilizer and / or a chemical is dropped and supplied into the crushed soil that is communicated at 17 and is conveyed in a large amount so as to be uniformly mixed. In the figure, 18 is a mixture delivery guide plate, 19 is a belt conveyor, and 20 is a motor.

In the above embodiment, the fertilizer and the like in the small-capacity hopper 15 is conveyed and dropped by the screw transfer body 16, but it is also possible to drop the fertilizer and the like that are going to fall by weight by a grooved roller or the like quantitatively. As it is possible, it is not limited to what is shown. Further, although the conveying direction of the screw transfer body 16 is shown to face the conveying direction of the screw transfer body 8, fertilizer or the like may be supplied above the falling flow path 17 in a substantially vertical posture. The direction is not specified.

By adjusting the number of revolutions of the motors 12 and 20, the conveying amount of the screw transfer bodies 8 and 16 can be adjusted, and the mixing ratio of the crushed soil and the fertilizer can be arbitrarily adjusted. Of course, adjustment is possible.

A screw transfer body 8b having a diameter larger than that of the screw transfer body 8 is integrally formed in a portion of the screw transfer body 8 on the lower side of conveyance, that is, a portion corresponding to the lower side of the hopper 15. It is housed in a large U-shaped carrier cylinder 7c. Thus, forming the lower half of the screw transfer body 8 on the lower transfer side into the screw transfer body 8b having a large diameter results in a high stirring / transfer speed and lack of uniform mixing. Therefore, as shown in FIG. The notch 8c may be formed at an appropriate portion of the section so that the transport speed is appropriately delayed to achieve uniform mixing.

[Effect of the Invention] According to the configuration of the present invention as described above, the following effects can be obtained.

(a) Fertilizers, chemicals, etc. are introduced into the crushed soil during the transportation by the screw transfer body 18, so that stirring is performed by the transfer action, and in addition, a large stirring action by the screw transfer body 8b with a large diameter is added. Therefore, it is possible to mix crushed soil, fertilizer and chemicals uniformly in a short time.

(b) a large-diameter screw transfer body 8b is used instead of the large-diameter rotary stirring cylinder, and the large-diameter screw transfer body 8b
The hopper 15 of fertilizer or the like having a conveying direction opposite to the conveying direction of the screw transfer bodies 8 and 8b and having a small conveying mechanism mounted on the machine frame is mounted on the machine frame above Since the sending part and the midway part of the screw transfer body 8 are communicated with each other through the falling flow path in a substantially vertical posture, the whole mixer can be compact and compact, and the crushed soil to the hoppers 7 and 15 can be compacted. ， It is easy to replenish fertilizer and improve the stable mixing work efficiency.

(c) It is possible to significantly reduce the work time and save labor.
