[0026] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] The additional aspects and advantages of the present utility model will be further given in the following description with reference to the drawings, and some will become obvious from the following description, or be understood through the practice of the present utility model.

[0028] As shown Figures 1 to 9 in the figure, a fry releasing device includes a release chute 1 and a bracket 2. An adjusting component 3 for adjusting the slope of the release chute 1 is arranged inside the bracket 2. Two floats 101 are symmetrically and fixedly installed at one end of the release chute 1 in contact with water. The end of the release chute 1 where the floats 101 are installed is defined as the front end. The adjusting component 3 includes a worm gear 301 and a worm 302 rotatably arranged inside the bracket 2. The worm gear 301 and the worm 302 are meshed with each other. A hand crank 3021 is fixedly arranged at the rear end of the worm 302. A rubber layer is arranged on the outer surface of the hand crank 3021. By using the arranged rubber layer, the comfort of the staff when holding the hand crank 3021 can be improved, which is convenient for the staff to control the rotation of the worm 302. A pin shaft 303 is axially inserted at the center of the worm gear 301. Both ends of the pin shaft 303 are rotatably connected to the bracket 2. An installation frame 304 that rotates synchronously with it is installed on the outer surface of the pin shaft 303. The release chute 1 is connected to the installation frame 304 through a sliding component 4. A positioning component 5 for restricting the sliding of the release chute 1 is arranged at the top of the installation frame 304. By using the cooperation between the worm 302 and the worm gear 301, the worm gear 301 drives the installation frame 304 to rotate through the pin shaft 303. Then, through the cooperation between the slider 401 and the slide rail 402, the slope of the release chute 1 is adjusted.

[0029] In summary, by setting the adjusting component 3 with the worm gear 301 and the worm 302, the slope of the release chute 1 can be flexibly adjusted according to actual needs. Thus, according to different water area conditions, water flow speeds, and factors such as the type and size of the fry, the chute can be adjusted to the best inclination angle, enabling the fry to enter the water at an appropriate speed and posture, reducing the impact and harm to the fry, and improving the survival rate of the fry.

[0030] As shown Figure 1 in Figure 3 and Figure 5 the figure, the sliding component 4 includes a slider 401 fixedly arranged at the bottom of the release chute 1. A slide rail 402 is slidably arranged on the slider 401. The slide rail 402 is fixedly installed at the top of the installation frame 304. One end of the slide rail 402 facing the float 101 extends outside the bracket 2. By designing the slide rail 402 to extend beyond the bracket 2, when the release chute 1 slides away from the water surface, the slide rail 402 can scrape the sludge on the surface of the slider 401, preventing the sludge from falling into the inside of the bracket 2. During production, the slider 401 and the slide rail 402 are in a closely attached state, so that the release chute 1 will not slide when no external force is applied.

[0031] In summary, the feeding chute 1 cooperates with the sliding assembly 4, and the length of the feeding chute 1 extending out can be flexibly adjusted by sliding according to the distance between the shore and the river bank, enabling the device to adapt to the shores of various different terrains and environments. Whether it is a wide river bank or a narrow river side, the length of the chute can be adjusted to accurately place the fry in the appropriate position, expanding the applicable range of the device.

[0032] As Figure 3 and Figure 7 shown, the positioning assembly 5 includes a positioning block 501. A support member 502 is fixedly provided at the bottom of the positioning block 501. The top of the positioning block 501 is in contact with the bottom of the slider 401. A first through hole 4021 is provided at the position of the slide rail 402 corresponding to the positioning block 501. A receiving groove 3041 is provided below the positioning block 501 on the mounting bracket 304. A second through hole 3042 is provided at the position of the mounting bracket 304 corresponding to the support member 502. A rubber layer is provided on the outer surface of the positioning block 501. By using the above-mentioned rubber layer, the friction between the positioning block 501 and the slider 401 can be increased. The bottom of the support member 502 is arc-shaped and is adapted to the engagement groove of the worm gear 301.

[0033] As Figure 3 、 Figure 6 、 Figure 8 and Figure 9 shown, the pin shaft 303 includes a shaft body 3031 and a pin block 3032. Connecting grooves 305 are provided at the positions of the mounting bracket 304 and the worm gear 301. The cross-section of the pin block 3032 is an isosceles trapezoid, and the connecting groove 305 is a rectangular groove. The length of the longest diagonal of the pin block 3032 is less than the width of the connecting groove 305. When the worm 302 causes the worm gear 301 to rotate, the connecting groove 305 of the worm gear 301 will abut against one side of the pin block 3032, so that the position of the worm gear 301 and the support member 502 deviates, and the support member 502 is no longer in the engagement groove of the worm gear 301. At this time, the support member 502 can cause the positioning block 501 and the slider 401 to be in close contact, thereby preventing the feeding chute 1 and the slider 401 from sliding randomly.

[0034] In summary, the positioning assembly 5 provided on the adjusting assembly 3 cooperates with the worm gear 301, and can realize reliable self-locking of the feeding chute 1 after adjusting the slope and the extending length of the feeding chute 1, further ensuring the stability of the feeding chute 1. Thus, during the fry feeding process, even if affected by external factors such as water flow impact and wind blowing, the feeding chute can remain stable without sliding or changing the inclination angle, ensuring that the fry can be accurately placed into the water area along the predetermined path, improving the accuracy and reliability of the feeding.

[0035] The working process is as follows:

[0036] S1. AsFigure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in Figure 5 , Figure 6 , during use, first place the bracket 2 on the flat ground by the shore, and then rotate the worm 302 by turning the hand crank 3021. At this time, using the cooperation between the worm 302 and the worm wheel 301, the worm wheel 301 drives the mounting bracket 304 to rotate through the pin shaft 303. After that, adjust the slope of the delivery chute 1 through the cooperation between the slider 401 and the slide rail 402;

[0037] S2. As Figure 3 , Figure 6 , Figure 8 and Figure 9 shown, when the worm 302 causes the worm wheel 301 to rotate, the engagement groove 305 of the worm wheel 301 will abut against one side of the pin block 3032, so that the positions of the worm wheel 301 and the support member 502 deviate, and the support member 502 is no longer in the engagement groove of the worm wheel 301. At this time, the support member 502 can cause the positioning block 501 to closely fit with the slider 401, thereby preventing the delivery chute 1 and the slider 401 from sliding randomly;

[0038] S3. As Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, when one end of the delivery chute 1 in contact with water cannot reach the water surface, rotate the worm 302 in the reverse direction by turning the hand crank 3021. The engagement groove 305 of the worm wheel 301 will abut against the other side of the pin block 3032, so that the positions of the worm wheel 301 and the support member 502 deviate, and the support member 502 is in the engagement groove of the worm wheel 301. Then the positioning block 501 no longer closely fits with the slider 401. At this time, the delivery chute 1 can be slid and adjusted;

[0039] S4. As Figure 3 , Figure 6 , Figure 8 and Figure 9 shown, when the adjustment of the delivery chute 1 is completed, rotate the worm 302 in the forward direction by turning the hand crank 3021, so that the engagement groove 305 of the worm wheel 301 abuts against one side of the pin block 3032, so that the positions of the worm wheel 301 and the support member 502 deviate, and the support member 502 is no longer in the engagement groove of the worm wheel 301. At this time, the support member 502 can cause the positioning block 501 to closely fit with the slider 401, thereby preventing the delivery chute 1 and the slider 401 from sliding randomly. At the same time, using the self-locking characteristic between the worm wheel 301 and the worm 302, the worm wheel 301 cannot rotate independently, so that the engagement groove 305 and one side of the pin block 3032 remain in contact;

[0040] S5. AsFigure 4 As shown, after the two floats 101 come into contact with the water surface, fry can be released into the water area through the release chute 1.

[0041] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
