Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to a greenhouse planting system for improving the survival rate of red claw crayfish. Background Art

[0002] Red claw crayfish have a history of artificial breeding and farming in my country for nearly 30 years. There are many artificial breedings in the Yangtze River Basin, such as Jiangsu, Anhui, and Hubei. Since red claw crayfish cannot naturally overwinter in the Yangtze River Basin, the red claw crayfish seedlings in the region are mainly obtained in two ways: one is pond breeding seedlings from southern regions such as Guangdong and Taiwan Province; the other is artificial breeding seedlings from local factory workshops. In late spring every year, farmers buy red claw crayfish seedlings from breeding farms or shrimp seedling dealers, put them in ponds for breeding, and then clear the ponds and sell the adult shrimps in autumn. The above breeding model is difficult to breed naturally, has a low survival rate, and has a high seedling cost, which seriously restricts the development and growth of the red claw crayfish industry.

[0003] In the prior art, a Chinese patent document with publication number CN105766748B proposes a pond greenhouse red claw crayfish seed breeding system. In the system, the heat preservation shed and the high-level water tank can ensure that the water temperature in the small pond is still maintained at 15°C to 20°C even in snowy weather. The algae and beneficial bacteria in the pond soil and water are in an active breathing state, which well maintains the water purification ability of the small pond itself. However, in actual application, like the traditional method, in summer, the red claw crayfish only relies on the shading effect of the greenhouse, which has a low utilization rate of the space in the greenhouse and low economic benefits. Although plants such as hanging loofah vines can be used for "ecological shading", the continuous growth of plants is accompanied by The longer the greenhouse is, the denser the shading effect on the underwater red claw crayfish, while the shading area on the greenhouse always remains unchanged. In this way, the double shading effect of the greenhouse shading and the loofah vine will affect the normal lighting of the breeding pond, thereby slowing down the production speed of the red claw crayfish. In addition, the shading area on the top of the greenhouse will also affect the lighting effect of plants such as loofah, which is not conducive to the normal growth of plants in the greenhouse. In addition, the greenhouse needs to be kept relatively sealed in winter to ensure the temperature in the greenhouse to adapt to the overwintering and reproduction needs of the red claw crayfish, but the current greenhouse is difficult to achieve rapid relative sealing. Therefore, the present application discloses a greenhouse planting system for improving the survival rate of red claw crayfish to meet the breeding and overwintering needs of red claw crayfish.

[0016] 1. The greenhouse planting system for improving the survival rate of red claw crayfish can not only improve the space utilization rate above the breeding pool and realize ecological agriculture by planting loofah on the net bag, but also provide shade for the red claw crayfish in the water below through the branches and leaves formed by the growth of loofah, which is beneficial to the growth of red claw crayfish and shortens the growth cycle of red claw crayfish. In addition, as the loofah continues to grow and gain weight on the net bag, the net bag sinks, and under the guidance of the column and the vertical slide, the main pulley and the auxiliary pulley rotate and drive the lifting seat to descend synchronously. Then, the rack plate is pulled downward by the connecting rope, thereby driving the rotating gears on both sides and driving the rotating shaft to rotate, and then the sunshade net is rolled up by the rotating winding roller, and multiple sunshade nets on both sides are synchronously moved to the middle of the ceiling and rolled up, thereby reducing the relative area of ​​the sunshade net to the transparent plate and increasing the light exposure to the net bag below. This can not only avoid the influence of excessive shading on the water temperature of the breeding pond, thereby affecting the normal growth of red claw crayfish, but also provide sufficient light for loofah, promote the extension and development of loofah, and optimize the breeding effect of ecological agriculture.

[0017] 2. The greenhouse planting system for improving the survival rate of red claw crayfish blocks sunlight through the sunshade net to adapt to the growth process of red claw crayfish. Under the counterweight action of the counterweight roller, multiple sunshade nets can be tensioned, and by setting the guide block, there will be no dislocation when the traction rope slides, so as to achieve stable movement of the sunshade net. In addition, in winter, by pulling down the counterweight roller and passing it through the gap on the limit seat and then placing it in the corresponding limit seat, the special structure of the limit seat is utilized, and the elastic force of the second spring is cooperated to make the sunshade net wrap around the periphery of the double-layer greenhouse, so as to increase the temperature inside the greenhouse in winter and ensure the growth environment of red claw crayfish to meet the needs of red claw crayfish's wintering and reproduction in winter. In addition, under the pulling force of the third spring, the arc plate is normally in contact with the inner wall of the limit seat. When it needs to be used, the counterweight roller can be "pushed out" of the limit seat by pushing the slide bar, which is convenient for operation and storage, and improves the convenience of the entire greenhouse planting system when in use.

A connecting strip 19 corresponding to the bottom end position of the connecting rope 17 is also installed on the net bag 6. The connecting strip 19 is made of hard material. One end of the sunshade net 7 located on the ceiling 3 is connected to a plurality of traction ropes 20 of the same length.

In addition, as the loofah continues to grow and gain weight on the net bag 6, the net bag 6 sinks, and under the guidance of the column 5 and the vertical slide 8, the main pulley 10 and the auxiliary pulley 11 rotate and drive the lifting seat 9 to descend synchronously, and then through the connection The rope 17 pulls the rack plate 16 downward, thereby driving the rotating gears on both sides and driving the rotating shaft 14 to rotate, and then the sunshade net 7 is rolled up by the rotating winding roller 15. The multiple sunshade nets 7 on both sides are synchronously moved to the middle of the ceiling 3 and rolled up, thereby reducing the relative area of ​​the sunshade net 7 to the transparent plate 4, and increasing the light exposure to the net bag 6 below. It can avoid the water temperature of the breeding pond 1 being affected by excessive shading, thereby affecting the normal growth of red claw crayfish, and can provide sufficient light for the loofah, promote the extension and development of the loofah, and optimize the breeding effect of ecological agriculture.

Under the counterweight action of the counterweight roller 21, multiple sunshade nets 7 can be tensioned, and by setting the guide block 22, there will be no misalignment when the traction rope 20 slides, so as to achieve stable movement of the sunshade net 7. In addition, in winter, by pulling down the counterweight roller 21 and passing it through the gap on the limit seat 24 and then placing it in the corresponding limit seat 24, the special structure of the limit seat 24 is utilized, and the elastic force of the second spring 18 is cooperated to make the sunshade net 7 wrap around the periphery of the double-layer greenhouse, thereby increasing the temperature inside the greenhouse in winter and ensuring the growth environment of the red claw crayfish.
