Description

Technical Field

[0001] The utility model belongs to the field of mulberry silkworm breeding equipment, and more specifically, relates to a device for manually adjusting the height of a cocoon frame. Background Art

[0002] When the silkworms are spinning cocoons, a cocoon rack is required in the silkworm room, and the square clusters are placed on the cocoon rack. By adjusting the hanging height of the cocoon rack to control the distance between the square clusters and the mature silkworms to be 1-2 cm, the mature silkworms will climb up the square grids in the cluster to spin silk and cocoon according to their own habits. After about 24 hours, the mature silkworms have finished cocooning, and the cocoon rack needs to be raised to clean the silkworm feces and keep the cocoon room ventilated and dry. At present, for most breeding farms with good production conditions, the height adjustment of the cocoon rack can be adjusted by a lifting mechanism, such as patent publication number CN209089732U, patent name A cocooning device for silkworm breeding, which uses a traction rope group, a pulley mechanism and a motor group to realize the lifting of the cocoon rack; patent publication number CN213881441U, patent name A large integrated silkworm room, which uses four take-up motors, four ropes, four fixed pulleys, four hooks and four movable pulleys to realize the lifting of the cocoon rack. Although using a lifting mechanism to achieve the lifting of the coco frame can facilitate the lifting and lowering adjustment of the coco frame, it requires increased investment costs. For reasons such as the failure to transform the lifting mechanism or for investment cost control, some farms still use the traditional wire rope fixing method, that is, one end of the wire rope is fixed to the roof of the silkworm house, and the other end is bound to the main beam of the coco frame. When adjusting the height of the coco frame, the coco frame is lifted to a predetermined height and then tied with the wire rope. However, there is a problem of adjusting the coco frame height unchanged. Utility Model Content

[0003] An object of the present invention is to solve at least the above problems and to provide at least the advantages which will be described below.

[0030] like Figure 1-4 As shown, the utility model provides a device for adjusting the height of a stacking frame, which includes:

[0031] A main chain 2, one end of which is provided with a first hook 5, and the first hook 5 is hung on a hook on the roof 1 of the silkworm house;

[0032] The first attached chain 6 has a second hook 10 and a third hook 9 at both ends thereof. The second hook 10 is hung on the iron ring of the main chain 2. After the first attached chain 6 is wound around the main beam 3 of the cluster at least once, the third hook 9 is hooked on the iron ring of the first attached chain 6 above the cluster.

[0033] The main chain 2 and the first attached chain 6 are both composed of a number of iron rings connected to each other. When in use, the first attached chain 6 can be wound around the main beam 3 of the cocoon frame by 1, 2, 3 or more turns, and then the third hook 9 on the first attached chain 6 is used to hook on the iron ring of the first attached chain 6 above the cocoon frame to achieve detachable fixation of the first attached chain 6 and the cocoon frame. The cocoon frame is lifted, and then the second hook 10 on the first attached chain 6 is used to hook on the iron rings at different positions of the main chain 2 to fix the cocoon frame at different heights. More specifically, the cocoon frame includes two main beams 3 and a number of attached beams 4, and the several attached beams 4 are connected and fixed to the two main beams 3. The main chain 2 is correspondingly arranged on the silkworm house roof above each end of the main beam 3, that is, the main chain 2 is arranged with 4 chains, and the positions correspond to the end positions of the main beam 3. The free end of the main chain 2 extends downward to 10-20 cm above the ground. The first attached chain 6 is fixed to the main beam 3 by the third hook 9 and then fixed to the main chain 2 by the second hook 10 .

[0034] In another technical solution, a second attachment chain 8 is further included, one end of which is connected to the middle of the first attachment chain 6, and the other end is provided with a fourth hook 7, which is suspended on the iron ring of the main chain 2. The second attachment chain 8 can be connected to the middle of the first attachment chain 6 through a connecting ring. When in use, the fourth hook 7 on the second attachment chain 8 is hooked on the main chain 2. In some specific technical solutions, a third attachment chain may also be included. In this case, a second hook 10 is provided at one end of the first attachment chain 6, and a connecting ring is provided at the other end. One end of the second attachment chain 8 and the third attachment chain are connected to the connecting ring, and the fourth hook 7 is provided at the other end of the third attachment chain, and the fourth hook 7 is provided at the other end of the second attachment chain 8.

[0035] In another technical solution, the length of the second attachment chain 8 is greater than the distance between the connection point between the second attachment chain 8 and the first attachment chain 6 and the second hook 10. When the second attachment chain 8 is connected to the middle of the first attachment chain 6 through the connecting ring, the length of the first attachment chain 6 between the connecting ring and the second hook 10 is less than the length of the second attachment chain 8. For example, the length of the second attachment chain 8 can be 30 cm, and the distance between the connection point between the second attachment chain 8 and the first attachment chain 6 and the second hook 10 is 25 cm. When hanging the cocoon, the first attachment chain 6 is in a tensioned state, while the second attachment chain 8 is in a relaxed state. When the cocoon is raised or lowered, the second hook 10 has been removed from the main chain 2. If the operator is physically exhausted or for other reasons, the fourth hook 7 is still hooked on the main chain 2, avoiding injuries to the operator caused by the fall of the cocoon, and damage to the cocoon and the grid cluster.

[0036] In another technical solution, character marks are provided on the iron rings of the main chains 2. The same character marks are provided on each main chain 2, which can facilitate the operator to hang the second hook 10 on the same position of the main chain 2 to ensure that the scaffold is in a horizontal state. The character marks can be Arabic numerals or English letters.

[0037] In another technical solution, the character identification is marked in order from top to bottom. The character identification can be marked in order from top to bottom, or from the bottom of the main chain 2 to the top.

[0038] In another technical solution, a mobile component is also included, and the mobile component includes:

[0039] Moving rod 11;

[0040] A first connecting hook 12, which is arranged at one end of the moving rod 11;

[0041] The second connecting hook 13 is disposed in the middle of the moving rod 11 , and the distance between the second connecting hook 13 and the first connecting hook 12 is greater than the distance between the second connecting hook 13 and the other end of the moving rod 11 .

[0042] In the technical solution, the moving rod 11 can be a cylindrical structure. The first connecting hook 12 can be detachably arranged with the moving rod 11, or can be integrally formed. The distance between the second connecting hook 13 and the first connecting hook 12 is 1 / 2-1 / 3 of the distance between the second connecting hook 13 and the other end of the moving rod 11.

[0043] The method of using the mobile assembly is as follows: when the cocoon frame needs to be lifted, the first connecting hook 12 is hooked on the main chain and is located below the second hook, the second connecting hook 13 is hooked on the first attached chain, and the other end of the moving rod 11 is lifted upward. At this time, the moving rod 11 bears the weight of the cocoon frame, and the second hook is moved upward and hooked on the main chain. This is repeated to continuously lift the cocoon frame. The technical solution uses the lever principle to lift the cocoon frame, which helps to save the physical strength required to lift the cocoon frame.

[0044] In another technical solution, an external thread is provided at the end of the first connecting hook 12, and an internal thread is provided at one end of the moving rod 11, and the first connecting hook 12 is threadedly connected to the moving rod 11. The threads of the first connecting hook 12 and the moving rod 11 are detachably arranged, so that after the first connecting hook 12 is damaged, it is convenient to replace the first connecting hook 12.

[0045] In another technical solution, the second connecting hook 13 is arranged on the side of the moving rod 11, and a limiter is arranged at the hook mouth of the second connecting hook 13. The limiter is rotatably arranged at the hook mouth to close or open the hook mouth. The limiter is used to prevent the second connecting hook 13 from falling off the iron ring of the first attachment chain when the rack is stacked on the table. It is also convenient to hang the moving assembly on the first attachment chain, which increases the convenience of use.

[0046] The method of using the utility model is as follows:

[0047] The main chain 2 is hooked on the roof of the silkworm house through the first hook 5. After the first attached chain 6 at the end of the third hook 9 is wound around the main beam 3 of the cocoon frame, the third hook 9 is hooked on the first attached chain 6 above the cocoon frame. The second hook 10 is hooked at a suitable position on the main chain 2 so that the grid cluster is about 4 cm away from the ground. At this time, the first attached chain 6 is in a tightened state, and the fourth hook is hooked at a suitable position of the main chain so that the second attached chain 8 is in a relaxed state.

[0048] When the height of the cobbling frame needs to be raised, if it is a single-person operation, lift one end of the cobbling frame main beam 3 by hand, the lifting height is about 20 cm, remove the second hook 10, move the second hook 10 upwards and hook it to a suitable position on the main chain 2, let go and hang the cobbling frame by the second hook, then remove the fourth hook 7, and hook the fourth hook 7 to a suitable position, the second hook 10 is in a tensioned state, the fourth hook 7 is still in a relaxed state, and the other three ends of the cobbling frame main beam 3 are lifted in the same way to make the cobbling frame in a horizontal state, and the cobbling frame is lifted to the required height through repeated operations; if it is a two-person operation, each person operates one end, and lifts the two ends of the cobbling frame at the same time according to the method of single-person operation, and then lifts the other two ends of the cobbling frame; if it is a four-person operation, each person operates one end, and lifts the cobbling frame at the same time according to the method of single-person operation.

[0049] When the height of the columbing frame needs to be lowered, first remove the fourth hook 7, move it downward about 20 cm, and hook it on the main chain 2, then lift the columbing frame by hand, take out the second hook 10, lower the columbing frame about 20 cm, hook the second hook 10 on the main chain 2, lower the other three ends of the columbing frame in the same way to make the columbing frame in a horizontal state, and lower the columbing frame to the required height through repeated operations; if it is operated by two people, each person operates one end, and lowers the two ends of the columbing frame at the same time according to the method of single-person operation, and then lowers the other two ends of the columbing frame; if it is operated by four people, each person operates one end, and lowers the two ends of the columbing frame at the same time according to the method of single-person operation.
