Description

Technical Field

[0001] The utility model relates to a feeding valve, in particular to a feeding valve with a double-opening gate, belonging to the technical field of aquaculture equipment. Background Art

[0002] The valve body gates of feed feeding equipment mainly include two structures: single-opening and double-opening. The traditional double-opening gate forms a blanking gap by synchronously opening two gate plates, so as to realize the feeding of feed. However, since the blanking gap is located at the center of the two gate plates, if the feed at the center position arches, the feeding process will be forced to stop. Therefore, the applicant has proposed a feeding valve with a double-opening gate. Content of the Utility Model

[0003] Aiming at the deficiencies of the above-mentioned prior art, the utility model provides a feeding valve with a double-opening gate.

[0004] To achieve the above object, the technical solution adopted by the utility model is: a feeding valve with a double-opening gate, including a valve body with a material port, three groups of guide rails are fixedly arranged on the valve body from top to bottom, a guiding interlayer is formed by enclosing between adjacent two groups of guide rails, the upper gate and the lower gate can be independently slid in the corresponding guiding interlayer under drive, and when a blanking gap is formed between the two, the feed inside the valve body can flow downward.

[0005] Preferably, the three groups of guide rails are the upper guide rail, the middle guide rail and the lower guide rail in sequence, and each group of guide rails includes two guide bars arranged symmetrically.

[0006] Preferably, the two guide bars of the middle guide rail are arranged to expand inside the valve body along the pushing direction of the upper gate, so that when the upper gate is pushed in, the feed adhered to itself can be scraped off.

[0007] Preferably, the two guide bars of the lower guide rail are arranged to expand inside the valve body along the pushing direction of the lower gate, so that when the lower gate is pushed in, the feed adhered to itself can be scraped off.

[0008] Preferably, the upper gate and the lower gate are respectively driven by a push rod I and a push rod II to slide independently in the guiding interlayer.

[0009] Preferably, the push rod I and the push rod II are installed on the mounting frame outside the valve body and are controlled by the controller arranged on the mounting frame to realize opening and closing.

[0010] The utility model has at least the following advantages:

[0011] 1. The upper and lower gates can form a blanking gap at any position, avoiding the arching and blocking of feed;

[0012] 2. The width of the blanking gap can be adjusted arbitrarily to adapt to the outflow of different types of feed;

[0013] 3. The upper and lower gates can scrape the feed adhering to the guide rails to prevent their own movement from being restricted. Description of the Drawings

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 - 5 shown: A feeding valve with double-opening gates includes a valve body 1 with a material opening penetrating up and down. The upper gate 2 and the lower gate 3 provided on the valve body 1 can close the material opening. When the upper gate 2 and the lower gate 3 move away from each other to form a blanking gap, the feed in the valve body can flow downward.

[0022] Furthermore, an upper guide rail 410, a middle guide rail 420, and a lower guide rail 430 are fixed in the valve body 1. Each group of guide rails 4 includes two symmetric guide bars 401. The two groups of guide rails adjacent up and down jointly enclose a guiding sandwich layer 5. The upper gate 3 and the lower gate 4 are clamped in the corresponding guiding sandwich layer 5 and can be driven by a driving element to slide.

[0023] Specifically, the drive elements for pushing and pulling to drive the upper gate 2 and the lower gate 3 to slide are the push rod Ⅰ 201 and the push rod Ⅱ 301 installed on the mounting bracket 101 outside the valve body 1. The push rod Ⅰ 201 and the push rod Ⅱ 202 are jointly controlled by the controller. Since the controller can drive the push rod Ⅰ 201 and the push rod Ⅱ 301 to expand and contract by different lengths by sending electrical signals, the feeding gap between the upper gate 2 and the lower gate 3 can be formed at any position.

[0024] In addition, during the downward flow of the feed, inevitably, part of it will adhere to the top surfaces of each group of guide rails 4. Since the upper gate 2 and the lower gate 3 are clamped in the guide sandwich 5 to achieve sliding, they will come into contact with the middle guide rail 420 and the lower guide rail 430 below themselves. When the two gates are pushed in, it is easy to simultaneously push the residual feed adhered to the middle guide rail 420 and the lower guide rail 430, resulting in its accumulation at the side position of the valve body 1. Therefore, for the middle guide rail 420 and the lower guide rail 430 in this embodiment, the two guide bars 401 are not parallel to each other, but are arranged in an expanding manner; as Figures 4 - 5 shown, the two guide bars 401 on the same horizontal plane are inclined relative to each other, thus forming an "eight"-shaped expanding structure. If this is done, when the gate is pushed in a straight line, the scraped residual feed will also move in a straight line, thus separating from the inclined guide bar 401.

[0025] Specifically, the expanding direction of the two guide bars 401 of the middle guide rail 420 and the lower guide rail 430 should be consistent with the pushing direction of the corresponding upper gate 2 and lower gate 3.

[0026] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
