Description

Technical Field

[0001] The utility model relates to the technical field of rice field crab breeding, in particular to a feeding device for rice field crabs. Background Art

[0002] Rice field crab farming is an ecological agricultural model, usually combined with rice cultivation to form a rice-crab symbiotic ecosystem. In this model, rice fields provide the natural environment needed for river crabs to grow and molt, while river crabs can clear rice field weeds and prevent rice pests. At the same time, their feces can improve soil fertility, realizing the recycling of agricultural resources and the improvement of the ecological environment.

[0003] When rice field crabs are farmed and fed, feed is usually spread into the rice fields manually. However, this method of manual feeding not only takes a long time, but also spreads the feed unevenly, which easily causes rice field crabs to gather and fight for food, ultimately leading to a low yield of rice field crabs. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the above-mentioned artificial feeding method not only takes a long time, but also spreads unevenly, which easily causes rice field crabs to gather and fight over food, and thus proposes a feeding device for rice field crabs.

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a feeding device for rice field crabs, comprising a rice field 1, a first mounting rod 2, a second mounting rod 3 and a feeding box 4, the first mounting rod 2 and the second mounting rod 3 are both fixedly mounted on the top of the rice field 1, the top of the first mounting rod 2 is fixedly connected to a fixing frame 1 21, a roller 22 is movably mounted on the inner side of the fixing frame 1 21, a steel rope 23 is provided on the surface of the roller 22, one end of the surface of the steel rope 23 is fixedly connected to a connecting rope 24, the top of the second mounting rod 3 is fixedly connected to a fixing frame 2 31, one side of the second mounting rod 3 is fixedly connected to a guide rod 5, the other end of the guide rod 5 is fixedly connected to the fixing frame 2 31, and the second side of the second mounting rod 3 is fixedly connected to the guide rod 5. The side is fixedly connected to the outer wall of the first mounting rod 2, the outer side of the fixing frame 2 31 is fixedly mounted with a second motor 6, the inner side of the fixing frame 2 31 are respectively movably mounted with a winding drum 7 and a unwinding drum 8, the bottom end of the outer wall of the feeding box 4 is fixedly mounted with a first motor 41, the interior of the feeding box 4 is fixedly mounted with a baffle 42, the inside of the feeding box 4 is movably mounted with a material dispensing cylinder 43, the bottom end of the baffle 42 is fitted with the top of the material dispensing cylinder 43, the surface of the material dispensing cylinder 43 is provided with a groove 431, and both sides of the material dispensing cylinder 43 are fixedly connected with a mounting shaft 44, and the side of one mounting shaft 44 is fixedly connected to the output shaft of the first motor 41.

[0024] In this embodiment, the rice field crab feed to be fed is put into the feeding box 4, the feed sinks to the bottom of the feeding box, and a small amount of feed falls into the groove 431 on the surface of the material-digging barrel 43. Then, by starting the first motor 41 to drive the mounting shaft 44 and the material-digging barrel 43 to rotate, the groove 431 on the top of the material-digging barrel 43 rotates to the bottom. At this time, the feed inside the groove 431 will fall downward, and at the same time, the groove 431 on the side of the material-digging barrel 43 moves the top to collect the feed again, and the reciprocating cycle is repeated to realize the feeding of the feed. When the first motor 41 is turned off to stop the rotation of the material-digging barrel 43, the feeding of the feed can be stopped. Example

[0025] like Figure 1-Figure 5 As shown, a sliding plate 51 is movably installed on the surface of the guide rod 5, the top of the sliding plate 51 is fixedly connected to the bottom of the connecting rope 24, and the bottom of the sliding plate 51 is fixedly connected to the top of the feeding box 4. The two ends of the steel rope 23 are respectively wound and installed on the surfaces of the winding drum 7 and the unwinding drum 8. One end of the surface of the winding drum 7 is fixedly connected to a transmission gear 71, and one end of the surface of the unwinding drum 8 is fixedly connected to a driven gear 81. The top of the transmission gear 71 is engaged with the bottom teeth of the driven gear 81, and the output shaft of the second motor 6 is fixedly connected to the side of the winding drum 7.

[0026] In this embodiment, when the feeding box 4 is feeding, the second motor 6 is started to drive the winding drum 7 to rotate. At the same time, due to the mutual engagement of the transmission gear 71 and the driven gear 81, the unwinding drum 8 rotates accordingly. The rotation directions of the unwinding drum 8 and the winding drum 7 are opposite. The unwinding drum 8 rotates to unwind one end of the steel rope 23, while the winding drum 7 reverses to rewind one end of the steel rope 23, and the surface of the steel rope 23 slides on the surface of the drum 22. When the steel rope 23 is retracted and released, the position of the connecting rope 24 is driven to adjust, and the connecting rope 24 drives the sliding plate 51 to move horizontally, so that the feeding box 4 can be moved and fed, thereby increasing the feeding range.

[0027] The working principle of this embodiment is as follows: the required feed is put into the feeding box 4, and a small amount of feed falls into the groove 431 on the surface of the material-dispensing cylinder 43. Then, by starting the first motor 41, the mounting shaft 44 and the material-dispensing cylinder 43 are driven to rotate, and the groove 431 at the top of the material-dispensing cylinder 43 rotates to the bottom, and the feed inside the groove 431 is thrown out. The material-dispensing cylinder 43 continues to rotate to release the feed. At the same time, the second motor 6 is started to drive the winding drum 7 to rotate, and the unwinding drum 8 rotates in the opposite direction. The unwinding drum 8 rotates to unwind one end of the steel rope 23, and the winding drum 7 reverses to rewind one end of the steel rope 23. At this time, the connecting rope 24 drives the sliding plate 51 to move horizontally, so that the feeding box 4 can be moved and released, thereby increasing the feeding range, and the uniform movement of the feeding box 4 can make the feed release more uniform.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
