Description

Technical Field

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

[0002] River crab farming refers to the breeding technology of river crabs. River crabs are the most important freshwater crabs in China. They have tender meat, delicious taste and extremely rich nutrition. Due to the strong adaptability of river crabs and the wide breeding range, the scale of breeding has increased rapidly in recent years, bringing good economic benefits to breeders. Farming crabs in rice fields is also a way to breed river crabs. Farming crabs in rice fields makes full use of the ecological conditions of shallow water levels, high water temperatures, sufficient dissolved oxygen, rich bait, and the ability to provide river crabs with a habitat and avoid harm, supplemented by artificial bait, and implements scientific management to properly resolve the contradictions in the symbiosis of rice and crabs, forming an efficient ecosystem of symbiosis between rice and crabs that is mutually beneficial. It has the significant characteristics of short breeding cycle, low investment risk, low incidence rate, stable grain production and increased efficiency.

[0003] When feeding river crabs, operators usually scatter river crab feed into the breeding waters manually, which is not only time-consuming and labor-intensive, but also the artificial scattering of feed is not very uniform, which will cause feed accumulation. Among them, a river crab feed feeding device with application number CN202023173813.0 can scatter feed evenly into the breeding waters. However, in order to increase farmers' income, rice fields and river crabs are usually cultured together to achieve the maximum utilization rate of farmland. For this breeding method, the river crab feed feeding device is no longer practical, because the rice field waters are shallow, and when the rice fields grow, the rice seedlings are too high, which will also block the operation of the river crab feed feeding device.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-7A rice field crab feed feeding device comprises: a flatbed car 1, a spreading bin structure is installed on the upper wall of the flatbed car 1, a spreading power structure is installed on the upper wall of the spreading bin structure, a silo structure is installed on the upper wall of the flatbed car 1, and four pneumatic lifting structures are installed on the lower wall of the flatbed car 1; the spreading bin structure comprises: a spreading base 2 and a spreading upper cover 3; the spreading base 2 is installed on the upper wall of the flatbed car 1, and the spreading upper cover 3 is installed on the upper wall of the spreading base 2 through three support rods, and a hole is opened on the upper wall of the spreading upper cover 3, and a bearing is installed inside the hole of the spreading upper cover 3 A gap is left between the scattering base 2 and the scattering upper cover 3, a handle is installed on the side wall of the flatbed truck 1, and the scattering power structure includes: a scattering motor 4, a transmission rod 5 and a scattering arc plate 6; the scattering motor 4 is installed on the upper wall of the scattering upper cover 3 through the motor frame, and the driving end of the scattering motor 4 passes through the bearing of the scattering upper cover 3, one end of the transmission rod 5 is installed on the driving end of the scattering motor 4, and the scattering arc plate 6 is installed at the other end of the transmission rod 5. The scattering power structure can scatter the feed staying inside the scattering bin structure in a circular manner to ensure that the crab feed can be evenly scattered in the breeding rice field.

[0029] Specifically, the silo structure includes: two silo rods 7, a storage bin 8 and a pipeline 9; the two silo rods 7 are respectively installed on the upper wall of the flatbed vehicle 1, the storage bin 8 is installed on the upper wall of the two silo rods 7, the pipeline 9 is installed between the storage bin 8 and the spreading cover 3, and the upper wall of the storage bin 8 is installed with a hopper 12. The silo structure can store river crab feed, which is convenient for the utility model to scatter feed while moving.

[0030] Specifically, the pneumatic lifting structure includes: a lifting cylinder 10 and a supporting base plate 11;

[0031] The lifting cylinder 10 is installed on the lower wall of the flatbed car 1, and a driving shaft 001 is sleeved and installed in the lifting cylinder 10. A sealing member 002 is fixed at one end of the driving shaft 001, and the other end of the driving shaft 001 is fixed to the supporting bottom plate 11. The sealing member separates the cylinder space of the lifting cylinder 10 into relatively independent upper cylinder cavity 003 and lower cylinder cavity 004. An upper air hole 006 connected to the upper cylinder cavity 003 is opened on the side wall of the lifting cylinder 10, and anti-slip nails are installed on the lower wall of the supporting bottom plate 11. The pneumatic lifting structure can lift the utility model, which can avoid the obstruction of the tall rice seedlings to the scattering of feed. During the process, an external small air compressor is placed on the working surface of the flatbed truck, and then the air outlet of the air compressor is connected to the upper air hole 006. When it is necessary to lift the drive shaft 001, the air compressor starts to work and injects compressed air into the upper cylinder cavity 003 to push the drive shaft 001 out, thereby lifting the working surface of the flatbed truck upward. When it is lifted to the target position, the injection of compressed air is stopped. Conventional air compressors have a self-locking function. When the air is stopped from being pumped into the upper cylinder cavity 003, it can be automatically locked to fix the position of the drive shaft 001, thereby fixing the working surface of the flatbed truck, thereby facilitating the spreading of feed.

[0032] Specifically, a one-way air valve 007 is installed on the upper air hole 005, and an upper air vent 009 connected to the upper cylinder cavity 003 is opened on the side wall of the lifting cylinder 10. During the operation, in some usage scenarios, such as adding feed to the hopper 12, the operator is required to climb onto the working surface of the flatbed truck, which will cause the pressure in the upper cylinder cavity 003 to increase sharply. If the air compressor is used for locking, the burden on the air compressor is relatively large. Therefore, a one-way air valve 007 is installed on the upper air hole 005. When the compressed air enters the upper cylinder cavity 003, the one-way locking is automatically completed and the air cannot escape in the reverse direction, thereby greatly alleviating the working pressure of the air compressor. When the working surface of the flatbed truck needs to be lowered, a valve plug is installed on the upper air vent 009, and the upper air vent 009 can be opened.

[0033] Specifically, the aperture of the upper air bleed hole 009 is less than 3 mm. The upper air bleed hole 009 is set in a small aperture. On the one hand, it avoids excessive pressure on the valve plug due to the aperture being too large, which is not easy to be blocked (when the pressure per unit area is the same, the larger the area, the greater the pressure on the valve plug). On the other hand, the air in the upper cylinder cavity 003 can be slowly discharged from the upper air bleed hole 009, so that the working surface of the flatbed truck can slowly descend, making the adjustment process smoother, and avoiding damage to the operating machine caused by a sudden drop in the working surface of the flatbed truck.

[0034] Embodiment 1: When using the present invention, the operator first places the battery used in the present invention on the upper wall of the flatbed truck 1 to power the electrical appliances in the present invention. The operator first starts the spreading motor 4. The rotation of the spreading motor 4 drives the transmission rod 5 to rotate, and the rotation of the transmission rod 5 drives the spreading arc plate 6 to rotate. At this time, the operator places the river crab feed into the interior of the storage bin 8 through the hopper 12, and the river crab feed will enter the spreading cover 3 through the pipe 9. When the feed falls above the spreading base 2, the rotating spreading arc plate 6 will scatter the river crab feed, thereby achieving the purpose of feeding the river crabs.

[0035] Embodiment 2: The utility model can be used for mobile feeding. Based on the premise of embodiment 1, the operator can move the flatbed cart 1 by the handle, so as to feed the crabs while moving, and can spread the crab feed over a larger area.

[0036] Embodiment three: The utility model can be used for high-altitude feeding. Based on the premise of embodiment one, the operator can extend the four lifting cylinders 10 respectively, so that the four supporting bottom plates 11 are located on the ground. At this time, the four extended lifting cylinders 10 can lift the flatbed truck 1, and high-altitude scattering can be achieved, which can prevent the seedlings from being too high to block the scattering of feed.

[0037] In one embodiment, when the initial working surface of the flatbed truck is too high, it will cause the center of gravity to be unstable during the pushing process, making it inconvenient to carry. Therefore, the lifting structure designed in the utility model is more in line with the actual production needs.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
