Description

Technical Field

[0001] This utility model belongs to the field of earthworm farming technology, specifically relating to a farming frame for raising earthworms. Background Technology

[0002] Earthworms, also known as earthworms, are terrestrial invertebrates belonging to the class Oligochaeta of the phylum Annelida. Earthworms can be used as valuable medicine to treat various diseases and can also be used as high-protein food and feed. Earthworms are nutritious, reproduce rapidly, have a varied diet, and are highly productive and economically viable when artificially bred. However, current large-scale field production methods result in low annual yields, and the area required to produce the currently needed dried earthworms is large. Therefore, only by establishing earthworm factories centered around feed ingredients and implementing intensive farming can the problem of insufficient yield be solved. The existing earthworm farming frame size and height are suitable for the high-density farming of *Eriocheir sinensis* (a type of earthworm), but *Eriocheir sinensis*, due to their larger size, are not suitable for gregarious living and are prone to escape, making them unsuitable for farming in existing frames.

[0003] Patent application CN202222511746.1 discloses an escape-prevention device for earthworm farming, comprising: several uprights with rope-tying grooves at their upper ends; and an escape-prevention net including side nets and a bottom net, the lower ends of which are connected to the bottom net, and the left and right ends of which are connected to form a farming space within the net. The upper ends of the side nets are connected to the rope-tying grooves. This utility model's escape-prevention net has a grooved structure, creating a farming space within it to prevent earthworms from escaping during farming and also facilitating feed delivery. However, earthworms require oxygen to grow, and the farming space created by the escape-prevention net makes it inconvenient to stir the feed inside, potentially causing the oxygen content in the feed to gradually decrease over time, affecting earthworm growth.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a breeding frame for raising earthworms, in order to solve the problem that the oxygen content in the breeding feed gradually decreases over time, affecting the growth of earthworms.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0030] See attached document Figure 1-4 A breeding frame for raising earthworms, comprising:

[0031] The support frame 1 has a clearance opening in the middle and four support legs 2 at the bottom;

[0032] The escape prevention frame 3 has a cover plate 4 on top and is fixed to the support frame 1 by bolts at the bottom; the cover plate 4 has a limit hole 5 in the middle.

[0033] The nylon net 6 is pressed between the support frame 1 and the escape prevention frame 3 on all four sides and is pierced by bolts at corresponding positions; livestock feed and soil are laid on the nylon net 6, so that the middle part hangs down naturally and passes through the avoidance opening;

[0034] A tray 7 is located on the outer side of the bottom of the nylon mesh 6, and a clamp 8 is provided on it. The clamp 8 is located on the inner side of the bottom of the nylon mesh 6, and two symmetrical air pipes 9 are vertically arranged on it. The air pipes 9 are open at the top and bottom and hollow inside, and multiple air holes 10 are opened on the side wall to facilitate the entry of external air into the breeding feed and provide the oxygen required for earthworm growth. The air pipes 9 are welded and fixed to the clamp 8, and their bottoms penetrate through the clamp 8 and the bottom of the nylon mesh 6, and are fixed to the tray 7 by nuts 11. A connecting plate 12 is also provided at the top of the air pipes 9, and a connecting ring 13 is provided on the upper surface of the connecting plate 12.

[0035] Motor 14 is located on cover plate 4, and its output shaft is connected to a winding reel 15; the pull rope on the winding reel 15 passes downward through the limiting hole 5 and is connected to the connecting ring 13. The pull rope is not shown in the attached drawing.

[0036] In this embodiment, symmetrical ventilation openings are provided on both sides of the escape-proof frame 3, and wire mesh 16 is provided at the ventilation openings. While achieving ventilation, it can prevent earthworms from climbing up the inner wall of the escape-proof frame 3 to the ventilation openings and escaping. A scraper 19 is horizontally placed inside the escape-proof frame 3, and an avoidance groove is provided in the middle of the scraper 19. The avoidance groove is located directly above the vent pipe 9, and its inner wall is provided with a brush 20.

[0037] In addition, a reinforcing rod 17 is provided between the support legs 2; a load-bearing plate 18 is provided between the reinforcing rods 17 at the front and rear ends of the support frame 1 for placing the tray 7, which can support the tray 7 and the nylon net 6 on which the livestock feed is laid, reduce the burden on the nylon net 6, and avoid the impact of the nylon net 6 breaking.

[0038] In actual use, the feed and soil are laid on the nylon net 6, with the height of the feed and soil not exceeding the height of the connecting plate 12 at the top of the vent pipe 9. After the earthworms are placed in, the pull rope on the winding reel 15 is passed through the limiting hole 5 on the cover plate 4 and the limiting groove in the middle of the scraper 19. The end of the pull rope is tied to the connecting ring 13 on the upper surface of the connecting plate 12, and then the cover plate 4 is closed. When it is necessary to stir the feed and soil, the motor 14 is started. The output shaft of the motor 14 drives the winding reel 15 to rotate, causing the pull rope to pull the ring and the connecting plate 12 to rise, which in turn drives the vent pipe 9, the clamp plate 8, and the support plate 7 to rise. When the tray 7 rises, it will cause the bottom of the nylon net 6 to move upward to the height of the original feed surface. During this process, the feed and soil on the nylon net 6 will move to both sides of the clamp 8. The stirring process will make the soil and feed more fluffy, which is more conducive to the growth of earthworms. At the same time, stirring will also make the feed fully contact the air in the escape-proof frame 3, which will help increase the oxygen content in the feed.

[0039] It should be noted that when the motor 14 drives the stranding disc to pull the support plate 7 and clamping plate 8 upwards, the vent pipe 9 passes through the clearance groove. The feed and soil attached to the side wall of the vent pipe 9 are scraped off by the brush 20, allowing the blocked vent holes 10 to breathe again. After the agitation is finished, the motor 14 rotates in the opposite direction, causing the support plate 7 and clamping plate 8 to descend to their initial positions, and the support plate 7 returns to the load-bearing plate 18.

[0040] This utility model discloses a breeding frame for earthworms. Earthworm feed and soil are laid on a nylon mesh 6 for earthworm rearing. A motor 14 drives the pull rope support plate 7 and movable clamp plate 8 on the winding reel 15 to rise and fall, thus agitating the feed and providing a more comfortable growth environment for the earthworms, maintaining sufficient oxygen content in the feed. Simultaneously, a ventilation pipe 9 is provided to facilitate the entry of external air into the feed when the motor 14 is not operating, preventing the oxygen content in the feed from gradually decreasing over time and affecting earthworm growth. It is very practical and has good market application prospects.

[0041] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
