Description

Technical Field

[0001] This utility model relates to the field of rice-shrimp farming technology, specifically an adjustable-depth feeding device for rice-shrimp farming. Background Technology

[0002] In rice-shrimp farming, juvenile shrimp (1-3cm in length) mainly feed in shallow water areas with a depth of 30-50cm, while adult shrimp (over 5cm in length) prefer deeper water areas of 60-100cm. Meanwhile, the water level needs to be dynamically adjusted (range 20-80cm) during the rice tillering and heading stages. Existing feeding methods have the following drawbacks:

[0003] Manual feeding: This method is labor-intensive, and the feed is easily spread by the water flow to the rice root area, resulting in low shrimp feeding rate and serious waste.

[0004] Fixed-depth feeding baskets: These are often suspended by ropes or fixed with weights, and the depth cannot be adjusted. When the basket is too deep during the juvenile shrimp stage, it makes it difficult for them to feed. When the basket is too shallow during the adult shrimp stage, it is easy for birds to peck at it. In addition, the fixed stability is poor, and it is easy to tilt and shift under the impact of water flow. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable-depth feeding device specifically for rice-shrimp farming, in order to solve the problems mentioned in the background art.

[0006] The technical solution of this utility model is: an adjustable depth feeding device for rice-shrimp farming, including an anchor support, a slide assembly installed on the top of the anchor support, a feeding component slidably installed inside the slide assembly, a trough plate fixed on the outside of the feeding component, and a tightening bolt threaded into the outside of the slide assembly to abut against the inner wall of the trough plate.

[0007] The aforementioned components achieve the following effects: the anchoring support provides a foundational fixation for the entire device, preventing overall displacement; the feeding component adjusts its height along the internal sliding structure of the slide assembly to accommodate water level requirements at different shrimp ages and rice growth stages; once the feeding component is adjusted to the target depth, the tightening bolt is screwed into the threaded hole on the outside of the slide assembly, ensuring tight contact between the end of the tightening bolt and the inner wall of the trough plate fixed to the outside of the feeding component. This friction restricts the relative sliding between the feeding component and the slide assembly, achieving flexible adjustment of the feeding depth and stable fixation after adjustment. This improves the device's adaptability to water levels at different stages of rice-shrimp farming and solves the problems of traditional fixed-depth feeding devices failing to meet the needs of multiple scenarios and being prone to displacement after adjustment.

[0008] Preferably, the anchoring support includes a base plate connected to the bottom end of the carriage assembly, and a plurality of detachable anchor rods are connected to the bottom of the base plate.

[0009] The aforementioned components achieve the following effects: the base plate serves as a connecting carrier, with its top end fixed to the bottom of the sliding frame assembly, providing stable support for the sliding frame assembly; the bottom end is connected to multiple detachable anchor rods, which are inserted into the mud bottom of the rice-shrimp paddy field during use. The interlocking action between the anchor rods and the mud enhances the overall stability of the device. When it is necessary to move the device or change the aquaculture area, the anchor rods can be pulled out of the mud and separated from the base plate, achieving the purpose of convenient installation, disassembly, and relocation of the device. This improves the reusability and ease of operation of the device and solves the problems of difficult disassembly and reassembly and non-reusability of traditional fixing methods (such as fixing with heavy objects or suspension with ropes).

[0010] Preferably, the carriage assembly includes a top ring, and a side support rod connected to the base plate is fixed at the bottom end of the top ring. The outer side of the bottom end of the feeding assembly is slidably attached to the side support rod.

[0011] The above components achieve the following effects: the top ring and the side support rod form a stable frame structure, the top ring limits and fixes the top of the side support rod, and the bottom end of the side support rod is connected to the base plate to form a sliding guide channel that runs vertically through the base plate; the outer side of the bottom end of the feeding component slides against the side support rod, so that the feeding component slides smoothly along the length of the side support rod when adjusting the depth, avoiding tilting or offset of the feeding component during the sliding process, thus achieving the purpose of stability and guidance when adjusting the depth of the feeding component.

[0012] Preferably, the feeding assembly includes an inner tube, a feeding platform is fixed to the bottom end of the inner tube, the feeding platform has a slot on its side that slides with the side support rod, and the bottom end of the inner tube has symmetrical guide ports.

[0013] The effects achieved by the above components are as follows: the inner tube serves as a feed storage and guiding channel, and the symmetrical guiding ports at the bottom can evenly guide the feed to the feeding platform below, avoiding concentrated accumulation of feed; the feeding platform provides a centralized feeding platform for shrimp, and the slots on its sides slide in conjunction with the side support rods, which not only ensures that the depth of the feeding platform is adjusted synchronously with the inner tube along the side support rods, but also restricts the radial rotation of the feeding platform, thus achieving the purpose of precise feed guiding, centralized feeding, and stable adjustment of the feeding platform, thereby improving feed utilization.

[0014] Preferably, a conical protrusion for guiding materials is fixed at the center of the top of the base plate.

[0015] The effect achieved by the above components is as follows: when the inner tube guides the feed to the feeding platform through the feed inlet, some of the feed that may fall to the bottom plate will come into contact with the conical protrusion. The inclined surface of the conical protrusion can disperse the feed in all directions and guide the feed to slide back onto the feeding platform, thus preventing the feed from accumulating and deteriorating on the top of the bottom plate. This achieves the purpose of preventing feed accumulation and improving feed utilization.

[0016] This utility model provides an improved, depth-adjustable feeding device specifically for rice-shrimp farming, which has the following improvements and advantages compared to the prior art:

[0017] When the feeding component is adjusted to the target depth, the tightening bolt is screwed into the threaded hole on the outside of the slide assembly, so that the end of the tightening bolt is in close contact with the inner wall of the trough plate fixed on the outside of the feeding component. The relative sliding between the feeding component and the slide assembly is restricted by friction, so as to achieve the purpose of flexible adjustment of the feeding depth and stable fixation after adjustment. This improves the adaptability of the device to water levels at different stages of rice-shrimp farming and solves the problem that traditional fixed-depth feeding devices cannot meet the needs of multiple scenarios and are prone to displacement after adjustment.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved, depth-adjustable feeding device specifically for rice-shrimp farming. The technical solution of this utility model is as follows:

[0025] In embodiments of this utility model, such as Figures 1-2As shown, the adjustable-depth feeding device for rice-shrimp farming includes an anchoring support component. The anchoring support component includes a base plate 1 connected to the bottom of the slide assembly 5. The bottom of the base plate 1 is connected to multiple detachable anchor rods 2. The base plate 1 serves as a connecting carrier, with its top fixed to the bottom of the slide assembly 5 to provide stable support for the slide assembly 5. The bottom is connected to multiple detachable anchor rods 2. When in use, the anchor rods 2 are inserted into the mud bottom of the rice-shrimp field. The interlocking action between the anchor rods 2 and the mud enhances the overall stability of the device. When it is necessary to move the device or change the farming area, the anchor rods 2 can be pulled out of the mud and separated from the base plate 1, thus achieving the purpose of convenient installation, disassembly and relocation of the device.

[0026] A slide assembly 5 is installed on the top of the anchor support. The slide assembly 5 includes a top ring 501. A side support rod 502 connected to the base plate 1 is fixed at the bottom end of the top ring 501. The outer side of the bottom end of the feeding component slides against the side support rod 502. The top ring 501 and the side support rod 502 form a stable frame structure. The top ring 501 limits and fixes the top end of the side support rod 502. The bottom end of the side support rod 502 is connected to the base plate 1 to form a vertically connected sliding guide channel. The outer side of the bottom end of the feeding component slides against the side support rod 502, so that the feeding component slides smoothly along the length direction of the side support rod 502 when adjusting the depth, and avoids the feeding component tilting or shifting during the sliding process.

[0027] A feeding assembly is slidably installed inside the slide frame assembly 5. The feeding assembly includes an inner tube 4, with a feeding platform 3 fixed to the bottom end of the inner tube 4. The feeding platform 3 has slots on its side that slide with the side support rod 502. The bottom end of the inner tube 4 has symmetrical feed guide ports. The inner tube 4 serves as a feed storage and guide channel. The symmetrical feed guide ports at the bottom end can evenly guide the feed to the feeding platform 3 below, avoiding concentrated feed accumulation. The feeding platform 3 provides a centralized feeding platform for shrimp. The slots on its side slide with the side support rod 502, ensuring both feeding and... The feeding platform 3 adjusts its depth synchronously with the inner tube 4 along the side support rod 502, which also restricts the radial rotation of the feeding platform 3. A conical protrusion 8 for guiding the feed is fixed at the center of the top of the bottom plate 1. When the inner tube 4 guides the feed to the feeding platform 3 through the feed inlet, some of the feed that may fall to the bottom plate 1 will come into contact with the conical protrusion 8. The inclined surface of the conical protrusion 8 can disperse the feed in all directions and guide the feed to slide back onto the feeding platform 3, thus preventing the feed from accumulating and deteriorating on the top of the bottom plate 1. This achieves the purpose of preventing feed accumulation and improving feed utilization.

[0028] A trough plate 7 is fixed to the outside of the feeding component, and a clamping bolt 6 is threaded into the outside of the slide assembly 5 to abut against the inner wall of the trough plate 7. When the feeding component is adjusted to the target depth, the clamping bolt 6 is screwed into the threaded hole on the outside of the slide assembly 5, so that the end of the clamping bolt 6 abuts tightly against the inner wall of the trough plate 7 fixed to the outside of the feeding component. The relative sliding between the feeding component and the slide assembly 5 is restricted by friction, so that the feeding depth can be flexibly adjusted and stably fixed after adjustment.

[0029] The working principle of the adjustable-depth feeding device for rice-shrimp farming provided by this utility model is as follows:

[0030] The device is fixed in the following way: In the anchor support, the bottom plate 1 serves as the connection base, and multiple detachable anchor rods 2 connected to its bottom are inserted into the mud bottom of the rice-shrimp field. The device is fixed as a whole through the interlocking action of the anchor rods 2 and the mud, providing stable support for subsequent operations.

[0031] Depth adjustment principle: The top ring 501 of the carriage assembly 5 and the side support rod 502 form a guide frame. The feeding platform 3 of the feeding assembly slides against the side support rod 502 through the side slot, so that the inner tube 4 and the feeding platform 3 can slide along the length of the side support rod 502. After adjusting to the target depth, tighten the abutment bolt 6 on the outside of the carriage assembly 5 so that it abuts against the inner wall of the slot plate 7 on the outside of the feeding assembly. The position of the feeding assembly is fixed by friction, so as to achieve precise depth adjustment.

[0032] Feeding principle: The inner tube 4 serves as a feed channel, and the stored feed falls evenly onto the feeding platform 3 through the symmetrical feed inlets at the bottom. The feeding platform 3 provides a concentrated feeding platform for shrimp and avoids feed diffusion. At the same time, the feeding platform 3 adjusts its depth synchronously with the inner tube 4 to ensure that shrimp of different ages feed at the appropriate water layer.

[0033] Feed anti-accumulation principle: The conical protrusion 8 at the top center of the bottom plate 1 can guide the feed that falls onto the bottom plate 1 to the surrounding area along the inclined surface, so that it slides back onto the feeding platform 3, preventing the feed from accumulating and deteriorating.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
