Description

Technical Field

[0001] The present invention relates to the technical field of rice field lobster farming, and particularly to an enclosure device and a farming method for rice field shrimp farming. Background Art

[0002] During the process of farming rice field shrimp, in order to prevent the lobsters from escaping from the farming rice field, farmers usually fix a 50-cm-high fence on the ridge to block the escape of the lobsters. However, there are some problems when fixing the fence, such as the instability of the insertion rods and the drooping of the fence.

[0003] When fixing the fence, people usually use a single insertion rod to insert into the soil and use the intervals between the insertion rods to fix the fence. However, due to the instability of the insertion rods, they may be skewed when being hammered and fixed, resulting in the drooping of the middle part of the upper end of the fence. Furthermore, the fence and the anti-escape plastic film droop together, unable to effectively prevent the lobsters from escaping. In addition, when people enter the farming rice field to observe the growth of the lobsters, they may collide with the insertion rods, causing the insertion rods to be skewed again and the fence to droop again. To refix the fence, it is necessary to untie the fence first and then refix the insertion rods. Summary of the Invention

Any numerical labels such as: first or second are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0028] Example 1

[0029] AsFigures 1 - 8 As shown in the figure, an enclosing device and a cultivation method for cultivating shrimps in paddy fields include a surrounding net 1 and support columns 2; fixing parts 2001 and placing parts 2002 are provided on the support columns 2;

[0030] It also includes a support base 3, a fixing rod 4, a water storage airbag 5, a plug 101 and a fixing piece 104; the lower end of the support column 2 is fixedly connected with the support base 3, and the support base 3 is of a hollow structure; four fixing rods 4 are fixedly connected to the lower end of the support base 3, and the fixing rods 4 are made of plastic; a water storage airbag 5 is connected inside the support base 3, and a detachable one-way valve is arranged in the water storage airbag 5. The detachable one-way valve only allows water to flow into the water storage airbag 5 for water injection, and the water storage airbag 5 is connected to the support base 3 through a water filling port; a plug 101 is arranged on the inclined surface of the support base 3, and the plug 101 is used to block the water filling port of the water storage airbag 5; a fixing piece 104 is clamped on the right side of the surrounding net 1, and two locking buckles 10401 are arranged on the fixing piece 104; the surrounding net 1 in a rolled-up state is detachably connected in the placing part 2002 on the support column 2. When the surrounding net 1 is in an open state, the upper end of the surrounding net 1 is flush with the support column 2, and the lower end of the surrounding net 1 extends beyond the fixing rod 4; an anti-escape plastic film 1001 is connected to the upper end of the surrounding net 1; as Figure 7 As shown in the leftmost figure, the anti-escape plastic film 1001 and the upper part of the surrounding net 1 in an open state are attached in an inverted J shape along the joint. Then, when looking down from top to bottom, the mutually attached surrounding net 1 and anti-escape plastic film 1001 are folded in a Z shape and collected in the placing part 2002. Then, as Figure 7 As shown in the rightmost figure, the part of the lower end of the surrounding net 1 that extends beyond the support base 3 after being folded in a Z shape is turned up and collected in the hollow structure of the support base 3.

[0031] It also includes support pieces 102; four support pieces 102 are connected to the bottom surface of the support base 3.

[0032] It also includes a thick card block 203 and a thin card block 204; a thick card block 203 is arranged in the placing part 2002, and the thick card block 203 is connected to the support column 2; a thin card block 204 is arranged in the placing part 2002, and the thin card block 204 is connected to the support column 2. A passage 20401 is formed between the thick card block 203 and the thin card block 204, and the passage 20401 only allows the unfolded surrounding net 1 to pass through.

[0033] The following describes the use of the enclosure device for rice field shrimp farming, hereinafter referred to as this device: First, the farmer digs a circular ditch with a width of 10 m and a depth of 10 m on the ridge outside the rice field for shrimp farming. Then, several support columns 2 are installed on the circular ditch at intervals of four to five meters. When the farmer digs the circular ditch and inserts and fixes the support columns 2, this device is provided with a support base 3 at the bottom of the support column 2. A water storage airbag 5 is arranged inside the support base 3, and a fixing rod 4 is also arranged on the lower side of the support base 3. Before inserting the support column 2, the fixing rod 4 is first inserted into the soil around the circular ditch. During the insertion process, the farmer observes whether the support piece 102 is completely in contact with the soil. When the support piece 102 is completely in contact with the soil, the support base 3 is located directly above the circular ditch. At intervals of four to five meters around the rice field for shrimp farming, several support columns 2 are arranged to enclose the rice field for shrimp farming. After all the support columns 2 are fixed, the farmer first selects a support column 2 and starts to unfold and fix the enclosure net 1. First, the fixing piece 104 on the selected support column 2 is unlocked by unlocking the locking buckle 10401 on the fixing piece 104, and the fixing piece 104 is taken out from the placement part 2002. Then, the enclosure net 1 is straightened by pulling the fixing piece 104 and fixed on the fixing part 2001 of the next support column 2. In this way, the cycle continues until the last fixing piece 104 is fixed on the fixing part 2001 of the first support column 2. After the enclosure net 1 encloses the entire rice field, the soil dug out from the circular ditch is filled back into the circular ditch again. At this time, the bottom end of the enclosure net 1 is located inside the circular ditch. When the soil fills the circular ditch, the two sides of the bottom end of the enclosure net 1 are fixed and filled with soil at the same time, and the soil is also filled under the support column 2 until the entire circular ditch is filled. Then, the farmer pulls out the plugs 101 in turn to inject water into the water storage airbags 5 on each support column 2. When injecting water, the one-way valve on the water storage airbag 5 prevents the water from flowing out when the water storage airbag 5 is closed. By injecting water into the water storage airbag 5, the weight of the lower end of the support column 2 is increased, and the water storage airbag 5 adapts to the unevenly filled soil, increasing the contact area with the soil, so as to prevent the support column 2 from being easily tilted due to accidental collision with the support column 2 by the farmer during frequent entry and exit in the future.

[0034] When fixing the support column 2 at an interval of one meter, when inserting the last fixed support column 2, the interval may be less than one meter. Therefore, there are a thick block 203 and a thin block 204 located in the placement part 2002 on the support column 2 as Figure 4As shown, the passageway 20401 is only for the single-layer enclosure net 1 to pass through. When pulling out the enclosure net 1, since both the thick clamping block 203 and the thin clamping block 204 are in damping sliding connection with the enclosure net 1, the breeding personnel need to use force to pull out the enclosure net 1. When the distance between the two support columns 2 is less than one meter, the breeding personnel pull out the folded and stored enclosure net 1, and limit the enclosure net 1 through the thick clamping block 203 and the thin clamping block 204, so that the subsequent enclosure net 1 that does not need to be pulled out is locked in the placement part 2002, avoiding the situation that the enclosure net 1 droops due to the insufficient distance of less than one meter but too much of the pulled-out enclosure net 1.

[0035] The above work process is to add a support base 3, a fixing rod 4 and a support piece 102 at the bottom of the support column 2. When in use, the fixing rod 4 is inserted into the soil on both sides of the ring groove, and when inserting, by observing the fitting situation of the support piece 102 with the soil, the support column 2 is perpendicular to the soil; by fixing the support base 3 above the soil, adding support to the bottom of the support column 2, so that it will not be skewed due to the frequent entry and exit of the breeding personnel and collision with the support column 2, and by adding a water storage airbag 5 inside the support base 3, after filling with water, the water storage airbag 5 contacts the soil, increasing the weight of the support base 3, fixing the support column 2, and by the water storage airbag 5 adapting to the unevenness of the landfill soil surface, increasing the contact area with the soil and deepening the fixing effect on the support column 2.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, as Figures 3 - 8 shown, it includes a connecting rope 103, a fixing ring 105, a clamp 106, a fixing seat 201 and a fixing pin 202; the water storage airbag 5 is initially higher than the support piece 102, and a connecting rope 103 is connected to the bottom surface of the water storage airbag 5; the other end of the connecting rope 103 is connected to a clamp 106; the top surface of the support column 2 is fixedly connected with a fixing ring 105, and the other end of the connecting rope 103 passes through the placement part 2002 and the fixing ring 105 and is connected to the clamp 106; a fixing seat 201 is fixedly connected to the upper part of the outer side of the support column 2; a fixing pin 202 is rotatably connected to the fixing seat 201.

[0038] The clamping part of the clamp 106 is provided with an anti-slip silica gel layer.

[0039] The fixing ring 105 is provided with an elbow pipe for guiding the pulling force direction of the connecting rope (103) to adapt to the clamp 106 to clamp the anti-escape plastic film 1001.

[0040] The orifice of the fixing ring 105 is designed in an arc shape to avoid long-term friction of the connecting rope 103 and break the connecting rope 103.

[0041] A fixing rope 10301 is provided on the connecting rope 103 at the right end of the anti-escape plastic film 1001.

[0042] It also includes counterweights 205; a number of counterweights 205 are arranged at intervals on the lower side of the enclosure net 1.

[0043] When the enclosure net 1 is pulled out from the support column 2, a number of counterweights 205 are arranged at intervals at the bottom end of the enclosure net 1. Then, the locking buckle 10401 is unlocked. When the enclosure net 1 is pulled out, the folded and then turned-up folding part of the enclosure net 1 that is folded downwards falls vertically and returns to its original state. At this time, the bottom of the enclosure net 1 contacts the bottom of the annular groove, and all the counterweights 205 are located in the annular groove. When the farmer pulls the fixing piece 104 to straighten the enclosure net 1 and fixes the fixing piece 104 to the fixing part 2001 of the next support column 2, since the counterweights 205 bring the entire bottom of the enclosure net 1 into the annular groove, it is avoided that during the manual pulling process due to the enclosure net 1 being pulled out too far, the enclosure net 1 is caught by the plants around the annular groove and the bottom of the enclosure net 1 is not entirely located in the annular groove. At the same time, the counterweights 205 are used to pull the enclosure net 1 to make the enclosure net 1 vertically taut.

[0044] When straightening the enclosure net 1 and fixing the fixing piece 104 to the next support column 2, the fixing rope 10301 on the anti-escape plastic film 1001 is wound around the fixing pin 202. At this time, the fixing pin 202 is close to the support column 2, and the anti-escape plastic film 1001 is fixed to the next support column;

[0045] After successively pulling out all the enclosure nets 1 to enclose the entire paddy field, the farmer pulls the clamp 106. After the connecting rope 103 connecting the clamp 106 is tightened, the clamp 106 is then clamped on the edge of the anti-escape plastic film 1001. At this time, the water storage airbag 5 is pulled up by the connecting rope 103. After all the clamps 106 are clamped, the plug 101 is pulled out, and the water storage airbag 5 is injected with water by using a pump. At the same time, all the injected water is intercepted in the water storage airbag 5 through a detachable one-way valve, avoiding that when the water storage airbag 5 is closed, the water inside the water storage airbag 5 is squeezed out under its own elastic force. After the water injection is completed, since the water storage airbag 5 expands, the bottom of the water storage airbag 5 contacts the soil buried in the annular groove at this time. Since the water storage airbag 5 expands and pulls the connecting rope 103 connected to its bottom end downwards, the connecting rope 103 is tightened. The other end of the connecting rope 103 is connected to the clamp 106. The downward movement of the connecting rope 103 causes the clamp 106 to drive the anti-escape plastic film 1001 to move to the left. At the same time, the right side of the anti-escape plastic film 1001 is fixed to the fixing pin 202 through the fixing rope 10301. At this time, the force that the clamp 106 drives the anti-escape plastic film 1001 to move to the left makes the anti-escape plastic film 1001 straight. When the enclosure net 1 needs to be replaced subsequently, only the enclosure net 1 needs to be removed and replaced, avoiding the anti-escape plastic film 1001 between the two support columns 2 from sagging due to the edge of the anti-escape plastic film 1001 not being straight, resulting in the escape of lobsters from the sagging part.

[0046] When the last enclosure net 1 is fixed, if not all of the enclosure net 1 needs to be pulled out, after the enclosure net 1 is pulled out and fixed, use the clamp 106 to hold the edge of the escape-proof plastic film 1001. At this time, since part of the enclosure net 1 is still collected in the placement part 2002, it affects the straightening of the edge of the escape-proof plastic film 1001. At this time, manually cut the escape-proof plastic film 1001 to facilitate the clamp 106 to pull the escape-proof plastic film 1001 and make its edge straight.

[0047] The above work process is to hold the edge of the escape-proof plastic film 1001 by the clamp 106, and then straighten the escape-proof plastic film 1001 by pulling the clamp 106, to avoid the middle of the escape-proof plastic film 1001 sagging, resulting in insufficient height of the enclosure net 1 and lobsters escaping from the sagging part of the escape-proof plastic film 1001. Then use the fixed pin 202 to push the escape-proof plastic film 1001 upward to make the escape-proof plastic film 1001 inclined with the front high and the rear low. At the same time, by turning over the escape-proof plastic film 1001 and pushing up one side of the escape-proof plastic film 1001, it can avoid the escape-proof plastic film 1001 being collapsed by rainwater and increase the escape-proof height of the enclosure net 1. At the same time, use the counterweight blocks 205 distributed at intervals at the bottom of the enclosure net 1 to ensure that the bottom of the enclosure net 1 is located in the ring ditch when the enclosure net 1 is pulled open.

[0048] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited by the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
