Description

[Detailed description of the invention] Industrial applications The present invention relates to a device for removing the ovaries of a fish.

Conventional technology FIG. 6 is a typical prior art perspective view.

The fish body with its head cut off is transported with its sides held by a transport bell (Go, 61), and its abdomen is pressed by an abdominal pressing member 62 to remove the ovary G.

Problems to be Solved by the Invention In the prior art described above, the abdominal pressing member 62 is attached in a direction approaching the conveyor bell (60, 61) by the spring 63 so as to come into contact with the abdomen of the fish body. has been done.

Therefore, the ovary G pushed out from the abdomen of the fish body by the a-part pressing member 62 may hang down due to its own weight and enter the moving path of the abdominal pressing member 62. In such a case, the ovary G will come into contact with the abdominal suppressing member 62 and be damaged.

An object of the present invention is to provide an egg retrieval device that can smoothly and reliably remove the ovary without damaging the ovary and improve the speed of the egg retrieval process.

Means for Solving the Problems The present invention comprises: a pair of conveyor belts that grip and convey both sides of a fish whose head has been cut off; an abdominal pressing member having a rotational axis and capable of moving toward and away from the abdomen of the fish; means for orally driving the abdominal pressing member in a direction counter to the movement of the fish; and a guide plate disposed upstream of the abdomen suppressing member in the conveying direction to hold and guide the ovary pushed out from the fish body by the abdominal suppressing member. This is a unique egg retrieval device.

Function According to the present invention, the abdomen of the fish whose head has been cut off is pressed by the abdomen suppressing member, and the ovary in the abdominal cavity is pushed out. The extruded ovary is guided along the guide surface of the guide plate and is removed without entering the movement path of the abdominal suppressing member. As explained in the photometer technique, there is no contact between the abdominal suppression member and the ovary, and therefore the ovary can be smoothly removed without damaging it. Furthermore, since the abdominal pressing member is forcibly driven, the egg collection processing speed is improved.

The vicinity of the head is curved toward the upstream side in the conveyance direction. When the fish body F is further transported in the transport direction A, the abdomen is pressed by the abdominal pressing member 17, and the ovary G in the abdominal cavity becomes in a state of protruding outward as shown in FIG. 4 (2). . When further transported, as shown in FIG. 4(3), the ovary G enters between the guide plates 16a and 16[+, and is guided while sliding on the guide surface 16b1 of the guide plate 16b. It is surrounded by organs (not shown) provided in advance under the guide plates 16a, 16b. When the fish body F is further transported and the abdomen pressing member 17 returns to the initial position lpo, that is, when the operation to take out the ovary G is completed, the rear end of the ovary G is guided as shown in FIG. 4 (4). Plate 16a
, 16b. Therefore, the rear part of the ovary G does not come into contact with the abdominal pressing member 17, and the abdominal pressing member 17 is at the pressing starting position r! During the movement from IP1 to the initial position fiPO, the tip of the ovary G touches the guide plate 16a.
, 16b, and as in the light lamp technology, the tip of the ovary G is moved by its own weight to the abdomen suppressing member 1.
It does not enter the movement route of No. 7.

In this way, the ovary G can be smoothly removed without being damaged during egg collection.

Next, instead of the above-mentioned embodiment, a so-called vertical transport device may be used, which transports the fish F with its tail upward and its abdomen facing the direction of travel. Device! A cross-sectional view near 10a is shown in figure ff15. In addition, the same reference numerals are attached to the parts corresponding to the above-mentioned embodiments. The ovary G consists of a pair of ovarian bodies Gl and G2 (indicated by phantom lines), which may differ in size depending on their growth rate. In such a case, the ovary G is pushed out to the right (direction 1 of the arrow) or to the left (direction 2 of the arrow) with respect to the cut of the fish body F whose head has been severed. is not uniform, therefore the pair of guide plates 16
It is necessary to provide a+IGl+. In addition, the fish body transport device r! of the embodiment described in flif! In No. 11, the extruded ovary is guided by the guide plate 161), so the guide plate 16a can be omitted.

Advantages and Advantages According to the present invention as described above, the ovary pushed out by the abdominal pressing member is guided by the guide plate, so that it can be removed without entering the movement path of the abdominal pressing member. This allows the ovary to be removed smoothly without coming into contact with the abdominal suppressing member and therefore without damaging the ovary. In addition, the abdominal pressing member is a forced type! Since IJJ is performed, the speed of egg collection processing is improved.
