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 homogenize the two. With such means, there is a problem that a lot of human power is required and a lot of time is required when the seedling preparation period is busy, and the compounding ratio of the both varies, which affects seedling raising.

An object of the present invention is to provide a mixer in which the mixing ratio of crushed soil and fertilizer, chemicals, etc. is automatically and continuously mixed, and the time and labor can be greatly reduced.

[Means for Solving the Problems] The structure of the present invention for solving the problems of the prior art is for a crushed soil in which a screw transfer body 8 having a large conveyance amount is mounted on a machine frame in a substantially horizontal posture on the lower bottom. In a mixer in which a hopper 7 is provided and a rotary stirring tube (14) having a substantially horizontal posture with an open front surface that rotates integrally with the hopper 7 is connected to the delivery end of the screw transfer body 8, the rotary stirring tube (14) The upper machine frame has a carrying direction opposite to the carrying direction of the screw transfer body 8,
In addition, a hopper (17) for fertilizers, chemicals, etc., which is mounted on a transport and discharge mechanism with a small transport amount, is mounted, and the delivery part of the transport and release mechanism and the delivery end of the screw transfer body 8 fall in a substantially vertical posture. It is connected through the flow path (19).

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

FIG. 1 is a vertical sectional side view, FIG. 2 is a sectional view taken along the line AA in FIG. 1, FIG. 3, and FIG. 4 are vertical sectional side views showing other examples of the rotary stirring cylinder.

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, the rear of the machine frame 1 is provided with a large-capacity hopper 7 having a U-shaped cross section at the bottom and containing a horizontal conveying cylinder 7a for containing crushed soil. There is.
A screw transfer body 8 having a large transfer amount is mounted on the transfer cylinder portion 7a of the hopper 7, and the diameter of the screw transfer body 8 and the diameter of the transfer cylinder portion 7a are substantially matched.
In addition, 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 fixed amount of the ground material is conveyed while the ground material in the hopper 7 is ground by the circular hole 9. Is done. Further, a pulley 10 is provided on the rear end shaft portion 8a of the screw transfer body 8, and the pulley 10 and the pulley 12 of the motor 11 mounted on the machine frame 1 are connected by a belt 13 to connect the screw transfer body 8 to the screw transfer body 8. It is configured to be provided with rotary drive.

Reference numeral 14 is a rotary stirring cylinder having a substantially horizontal posture with an opening 14a formed in the front surface, and a window 14b adjacent to the circular hole 9 is formed on the rear surface of the rotary stirring cylinder 14, and the screw is inserted through the window 14b. The delivery end of the transfer body 8 and the lower end of the transfer cylinder 7a are slightly inserted into the rotary stirring cylinder 14. The outer periphery of the front end portion of the rotary stirring cylinder 14 is supported by a plurality of guide wheels 15 axially supported by the machine frame 1 as shown in FIGS. 1 and 2, and the tip shaft portion 8b of the screw transfer body 8 is It is fixed to the tip of an arm 16 provided inside the rotary stirring cylinder 14, and is configured so that the rotary stirring cylinder 14 rotates together with the screw transfer body 8.

Reference numeral 17 denotes a small-volume hopper provided on the upper side of the machine frame 1, and the hopper 7 contains fertilizer and / or medicine. A screw transfer body 18 having a small transfer amount is provided on the lower bottom of the hopper 17 in a substantially horizontal posture so that the contents are transferred in a direction opposite to the transfer direction of the screw transfer body 8. The delivery end of the body 18 and the delivery end of the screw transfer body 8 are made to communicate with each other through the falling flow path 19 in a substantially vertical posture, and a small amount of fertilizer and / or chemicals is added to the crushed soil that is transported in a large amount. Is supplied by dropping and mixed. In the figure, 20 is a mixture delivery guide plate, 21 is a belt conveyor, and 22 is a motor.

FIG. 3 shows another example of the rotary stirring cylinder 14, in which a plurality of stir pieces 23 are diagonally arranged in a row in the front-back direction of the inner surface of the rotary stirring cylinder 14 so that crushed soil, fertilizer, etc. It is designed to perform a stirring action and a feeding action. Also, the fourth
In the figure, a stirring spiraler 24 having a spiral strip-shaped plate is arranged inside the rotary stirring cylinder 14 to stir and convey crushed soil and fertilizer. In the embodiment shown in FIGS. 3 and 4, since the rotary stirring cylinder 14 itself has a carrying capacity, the rotary stirring cylinder 14, that is, the machine frame 1 is in a horizontal posture, is used to carry and supply crushed soil, fertilizer, etc. Is something that can be done.
Therefore, in the case of the rotary stirring cylinder 14 which does not have the carrying function as shown in FIGS. 1 and 2, the rotary stirring cylinder 14 as shown in FIG.
14, that is, the mixing operation is performed with the machine frame 1 in the forward tilted position.

In the above embodiment, the fertilizer or the like in the small-capacity hopper 17 is conveyed and dropped by the screw transfer body 8. However, the fertilizer or the like which is about to fall by its own weight may be dropped quantitatively by a grooved roller or the like. As it is possible, it is not limited to what is shown.

By adjusting the number of rotations of the motors 11 and 22, the conveying amount of the screw transfer bodies 8 and 18 can be adjusted, and the mixing ratio of the crushed soil and the fertilizer can be arbitrarily adjusted. Of course, adjustment is possible.

[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 put into the crushed soil during the transportation by the screw transfer body, so that the stirring action is carried out by the transporting action, and in addition, the stirring action in the rotary stirring cylinder is taken into consideration, so that it is uniform. Mixing can be done in a short time.

(b) A hopper 17 for fertilizer or the like, which has a conveying direction opposite to the conveying direction of the screw transfer body 8 and has a conveying and discharging mechanism having a small conveying amount, is mounted on the machine frame portion above the rotary stirring cylinder 14 The delivery section of the delivery and discharge mechanism and the screw transfer body 8
Since it is connected to the delivery end portion of the device through the falling flow path in a substantially vertical posture, the overall size of the mixer can be reasonably downsized, and the mixing ratio of fertilizer or chemicals with crushed soil can be accurately achieved.

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