First, the rotary cutter 10 shown in FIG.
A relatively thin stainless steel plate with a thickness of about 5 mm is integrally formed by punching the outer circumference into a circular shape and the inside into a substantially semi-arc shape, fan shape, etc. using a press machine. , a bearing plate portion 10b at the axial center position, and a plurality of spoke plate shapes, rib plate shapes, and wing plate shapes that are divided into 2 to 6 equal parts in the radial direction between the outer peripheral plate portion 10a and the bearing plate portion 10b. , a plate portion 10c in the shape of a partition plate, a connecting plate, etc. (hereinafter simply referred to as a spoke plate portion). 17 is Yamabe 1
7a and troughs 17b are arranged in a row alternately, and the spoke plate part 10c has a wavy shape on both sides.
After punching into a mountain shape, zigzag shape, etc., the cutting edge 17c is cut along the shape of the cutting portion 17 using a vertical end mill, a drill machining center, or the like.

Therefore, as shown in FIG. 5a, the blade portion 17 of the rotary cutter 10 usually has a trapezoidal cross section with cutting edges 17c machined on both sides of the spoke plate portion 10c, and the hydraulic motor of the prime mover 7 rotates in forward and reverse directions. cases are dealt with. Reference numeral 18 is a square hole drilled at the axial center position of the bearing plate portion 10b, and is inserted into and supported by the square shaft portion 9b of the shaft 9.

In the above case, there are blade parts 17 and blade edges 17c on both sides of the spoke plate part 10c as shown in FIG.
However, if the motor 7 is to be rotated only in one direction, the blade portion 17 and the cutting edge 17c are provided only on one side as shown in FIG. 17 is formed on both sides, but the cutting edge 17c
It is also possible to provide the rotary cutter 10 on the front side of one side and the rear side of the other end so as to have a parallelogram cross section, and to use the rotary cutter 10 by turning it from front to back.

Further, in the case of the rotary cutter 10 described above, the outer circumferential plate portion 10a, the bearing plate portion 10b, and the spoke plate portion 1
0c, in particular, the outer peripheral plate part 10a
Since it is integrally formed into an annular shape, it is useful for increasing the strength of the entire cutter and preventing collision with the cutting edge of the fixed cutter 11. However, as a second best measure, the rotating cutter 10 is integrally formed as described above. It is composed of a bearing plate portion 10b and a spoke plate portion 10c, that is, a wing plate portion, and the blade portion 17 may be formed in a wave shape, a mountain shape, etc. on both sides or one side of the plate portion 10c.

In addition, the fixed cutter 11 shown in FIG. 2b is made by using a press machine to form a relatively thin stainless steel plate with a thickness of about 2 to 5 mm, in the same way as the rotating cutter 10 described above. It is integrally formed by punching into an arc shape, fan shape, etc., and includes an annular outer peripheral plate portion 11a, a bearing plate portion 11b at the axial center position, and a radial direction between the outer peripheral plate portion 11a and the bearing plate portion 11b. It consists of a plurality of spoke plate parts 11c divided into two to three equal parts. 19 is the peak part 19a and the valley part 1
The spoke plate part 11c is a blade part in which the spoke plate parts 11c are punched out in a wave shape, a mountain shape, a zigzag shape, etc. on both sides of the spoke plate part 11c. Blade part 1 in this case
9, the cutting edge is not specially cut along the shape of the blade part 19 in principle, but the cutting edge is cut in the same manner as in the case of the rotary cutter 10, and as shown in FIG.
Spoke plate portion 1 symmetrical or the same as shown in ~c
It can also have a cross-sectional form of 1c. Reference numeral 20 indicates a through hole drilled at the axial center position of the bearing plate portion 11b, and reference numeral 21 indicates small holes drilled above and below the through hole 20.
After fixing the bearing metal 12 fitted into the screw 12a screwed into the small hole 21,
2 is inserted into and supported by the round shaft portion 9c of the shaft 9.
Reference numeral 22 denotes a large number of through holes bored in the outer circumferential plate portion 11a, which are fixedly supported on the inclined flange 3 together with the annular spacer 14 and the flange 16 of the hood 15 with bolts and nuts 23.

An example of a combination of such a rotary cutter 10 and fixed cutter 11 is shown in FIG. 3, in which the spoke plate portion 11c of the fixed cutter 11 has two blades, and the spoke plate portion 10c of the rotary cutter 10 has two blades. In figure a, 4
The case of a single blade is shown in Figure b, and the case of a six blade is shown in Figure c. In addition, in Figure 4, the spoke plate portion 11c of the fixed cutter 11 has three blades, and this and the spoke of the rotating cutter 10 are shown. A case in which the plate portion 10c has two blades is shown in Figure a, a case in which it has four blades is shown in Figure b, and a case in which it has six blades is shown in Figure e. In addition, the relevant figures 3 and 4
As is clear from the figure, when the rotating cutter 10 and the fixed cutter 11 are combined, the rotating cutter 1
The peak portion 17a of the blade portion 17 provided on the spoke plate portion 10c of the fixed cutter 11 is connected to the spoke plate portion 11c of the fixed cutter 11.
The rotating shaft is overlapped in a positional relationship between the troughs 19b of the blade portion 19 provided in the blade portion 19, that is, between the peak portions 19a of one pitch of the blade portion 19, with a difference of about half a pitch from each other. When the cutter 9 is inserted and supported, the aquaculture feed X is cut with an even sharper cutting edge. Next, the overall outline of the feeding apparatus in which the aquaculture feed X constructed as described above is equipped with the cutting machine K will be explained with reference to FIGS. 6 and 7.

Reference numeral 24 denotes a feeding boat that loads aquaculture feed
6, and a horizontal transfer screw conveyor 28 with one end facing the feeding outlet 27 and a base end rotatably supported is disposed at the bottom of the opening. 29 is the prime mover of the screw conveyor 28, and 30 is a communication path formed directly below the screw conveyor 28 in parallel with it, or directly below the feeding outlet 27 and perpendicular thereto, and at its base end. There is a blow pipe 31
is installed vertically. 32 is an air blower, and its discharge port and air pipe 31 are connected through a hose 33. Reference numeral 34 is a feed pipe which is inclined diagonally upward from the feed outlet 37, and a hose 35 is connected to the upper end of the feed pipe. Reference numeral 36 is a mast erected and fixed on the feeding boat 24, and has a boom 37 extending toward the fish cage in the aquaculture fishing area. Reference numeral 38 denotes a feed pipe suspended from the boom 37, and its base end is connected to the hose 35, and the other end is connected and fixed to the flange 2 of the case body 1 of the cutting machine K.

Then, the feeding boat 24 is loaded with the aquaculture feed X, approaches the fish tank defined in the aquaculture fishing area, and moves the motor 29 of the lateral screw conveyor 28 and the blower 3.
2 and the prime mover 7 of the cutting machine K are respectively driven. Then, the aquaculture feed X falls from the center opening 26 of the substrate 25 and is sent out from the feed outlet 27 into the communication path 30 by the screw conveyor 28, and at the same time, the feed X falls through the hose 3 by the compressed air from the blower 32.
5. It is fed through the feed pipe 38 and is pneumatically fed from the feed inlet 1a to the feed outlet 1b of the cutting machine K. In this way, the whole aquaculture feed X that has been air-fed into the case body 1 passes through the fan-shaped, semi-arc-shaped, etc. space 38 between the spoke plate parts 10c and 11c of the rotating cutter 10 and the fixed cutter 11. At this time, the fillet feed is cut into pieces of a required size by the rotational force of the rotary cutter 10 and the air feeding force, and then dispersed into the cage near the bottom of the fillet feed.

In addition, even in the case of seawater baiting, since the thin-walled stainless steel rotary cutter 10 is used, there is less resistance to cut the fed seawater, and it can cut the bait as well as in the case of air baiting. .

In the above case, the cutter K was configured at the tip of the feed pipe 38 extending directly above the fish pen, but the cutter K was configured at the tip of the feed pipe 38 extending directly above the fish cage, but the cutter K was configured at the tip of the feed pipe 38 extending directly above the fish tank. It can be constructed in the pipe 34, or it can be separately provided in the feeding boat 24 so that the fillet feed once cut by the cutter K can be fed with air or seawater.

The present invention provides an aquaculture feed cutting machine configured to cut aquaculture feed by combining a rotating cutter and a fixed cutter as described above, in which one side of the case body of the cutting machine is used as a feeding inlet, and the other side is an oblique cutter. The feed outlet is cut downward, with an inclined flange on its outer periphery, a prime mover is fixed to the support base of the case body, a rotary shaft is connected to the prime mover, and a rotary cutter can be rotated at the tip of the shaft. The outer peripheral plate of the fixed cutter is fixed to the inclined flange, the bearing plate of the fixed cutter is fixed to the tip of the rotating shaft, and the rotating cutter and the fixed cutter are integrated with a relatively thin steel plate. The rotary cutter is formed by press working, and the rotary cutter is formed from at least a bearing plate part and a spoke plate part, a blade part consisting of a peak part and a valley part is connected to the spoke plate part, and the blade part is A cutting edge is formed, and the fixed cutter is formed from an annular outer circumferential plate part, a bearing plate part at the axial center position, and a plurality of spoke plate parts that partition the outer circumferential plate part and the bearing plate part in the radial direction. Since the aquaculture feed cutting machine has a blade section consisting of peaks and troughs connected to the spoke plate, it is possible to efficiently cut the feed in the field of aquaculture and fisheries, significantly improving the feed yield, and further It prevents pollution of fishing areas and reduces the occurrence of fish diseases, and is also extremely effective in saving labor by relieving the heavy labor of cutting and casting bait.

At that time, the rotary cutter and the fixed cutter were formed by integrally pressing a relatively thin steel plate, and the spoke plate part of the cutter was provided with a blade section consisting of peaks and valleys. Not only is the merit of being lightweight as a cutter for cutting in a cutting machine significant, but the blades of both cutters bite sharply into the fed aquaculture feed, making it possible to cut the feed with sharpness. Furthermore, if the blades of the rotating cutter and the fixed cutter are overlapped in a positional relationship such that the peaks of the rotating cutter are the troughs of the fixed cutter, and the hood is fixedly supported on the inclined flange, the above case will occur. It exhibits a sharper biting force compared to the hood, and can cut the feed with excellent sharpness, and is also very convenient for adjusting the degree of dispersion of the aquaculture feed cut by the hood.

In addition, both the rotary cutter and the fixed cutter in the above case can be mass-produced using an NC press machine, etc.
Approximately 6 cutters can be selected and used as appropriate, and a wide variety of highly compatible cutters are available and can be used to quickly respond to various types of feed cutting. However, the usefulness of this type of cutting machine for aquaculture feed in reducing the size and weight of the device brings about significant effects.
