Description

Technical Field

[0001] This utility model relates to the field of wheat breeding technology, specifically to a wheat breeding experimental field fixing frame with an anti-lodging structure. Background Technology

[0002] Wheat is prone to lodging in breeding test fields due to factors such as wind, rain, and increased ear weight, which can cause the plant stems to bend or break, seriously affecting photosynthesis, pollination efficiency, and final yield. Lodging can reduce the yield of wheat in test fields and also lead to the distortion of test data, affecting the accuracy of breeding evaluation. In test fields, the binding method is generally used to prevent wheat from lodging. This method not only easily damages the stems and hinders the natural growth of the plants, but also the process of adjusting the binding height is very cumbersome and difficult to adapt to changes in plant height at different growth stages. Therefore, there is an urgent need for a wheat breeding test field fixing frame with an anti-lodging structure. Utility Model Content

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-6 As shown, this specific embodiment adopts the following technical solution: It includes a support frame 1 and a No. 1 ground nail 2. Several No. 1 ground nails 2 are fixedly installed at the bottom of the support frame 1. Support rods 19 are fixedly installed in the grooves opened on the left and right sides of the bottom of the support frame 1. Several No. 2 ground nails 20 are fixedly installed at the bottom of the support rods 19. Through the cooperation of the support rods 19 and the No. 2 ground nails 20, the wind resistance performance of the support frame 1 can be fully improved, making the support frame 1 more stable on the ground.

[0028] It also includes:

[0029] The lifting frame 3 is located above the support frame 1, and the support frame 1 is provided with a height adjustment mechanism 4 connected to the lifting frame 3;

[0030] Connecting rods 5, of which there are several, are fixedly installed on the front and rear side walls of the lifting frame 3 respectively. A movable rod 6 is movably installed inside the connecting rod 5. A rack 7 is fixedly installed on the left and right side walls of the movable rod 6. A positioning half ring 8 is hinged to the left and right sides of the connecting rod 5. An incomplete gear 9 that meshes with the rack 7 is fixedly installed on the positioning half ring 8. A flexible pad 21 is fixedly installed on the inner arc wall of the positioning half ring 8. The flexible pad 21 can prevent the wheat stalk from directly contacting the positioning half ring 8 and causing damage. Reinforcing ribs 22 are provided on the upper and lower side walls of the positioning half ring 8. The reinforcing ribs 22 can effectively improve the structural strength of the positioning half ring 8, thereby reducing the risk of deformation of the positioning half ring 8 due to external forces.

[0031] The control lever 10 is inserted into the lifting frame 3 through a bearing. Several first bevel gears 11 are fixedly sleeved on the control lever 10. The right end of the control lever 10 passes through the lifting frame 3 and is fixedly equipped with a control handle 12.

[0032] A control screw 13, wherein there are several control screws 13, which are respectively inserted into several connecting rods 5 through bearings. A movable rod 6 is rotatably sleeved on the control screw 13 through a thread. A second bevel gear 14 that meshes with the first bevel gear 11 is fixedly sleeved on one end of the control screw 13.

[0033] The height adjustment mechanism 4 includes:

[0034] Linkage 4-1, of which there are several, is respectively disposed in several storage slots 15 opened on the support frame 1. The lower end of the link 4-1 is hinged to a slider 4-2, which is slidably disposed in a sliding groove 16 opened on the bottom wall of the storage slot 15. The upper end of the link 4-1 is hinged to the lifting frame 3. Several drainage grooves 17 are opened on the front and rear side walls of the support frame 1, which are connected to the sliding grooves 16. The drainage grooves 17 are inclined so that when it rains, the water falls into the drainage grooves. Rainwater in 16 can be discharged through drainage channel 17 to avoid water accumulation in the channel 16 and affecting the sliding of slider 4-2. Guide baffles 18 are fixedly installed on the front and rear side walls of the support frame 1, and the guide baffles 18 are located below the drainage channel 17. The guide baffles 18 can protect the area below the opening of the drainage channel 17, preventing rainwater from dripping onto the soil and causing mud and water to splash into the opening of the drainage channel 17, thereby preventing the drainage outlet from being blocked.

[0035] A composite threaded rod 4-3 is rotatably mounted inside the lifting frame 3 via a bearing. A slider 4-2 is rotatably mounted on the composite threaded rod 4-3 via a thread. The threads of adjacent threaded sections on the composite threaded rod 4-3 are arranged in opposite directions. An adjustment handle 4-4 is fixedly mounted on the right end of the composite threaded rod 4-3 after passing through the support frame 1. The slider 4-2 can slide in the slide groove 16 by rotating the composite threaded rod 4-3. With the cooperation of the connecting rod 4-1, the lifting frame 3 can be moved up and down to adjust the support height of the wheat according to the different growth stages of the wheat.

[0036] When using this invention, the support frame 1 is placed between two adjacent rows of wheat in the experimental field, so that the No. 1 ground nail 2 and the No. 2 ground nail 20 are inserted into the soil to fix the support frame 1 in the experimental field. Then, the control handle 12 can be rotated, which drives the control rod 10 to rotate. The control rod 10 drives several No. 1 bevel gears 11 to rotate. By utilizing the meshing of the No. 1 bevel gears 11 and the No. 2 bevel gears 14, the synchronous rotation of several control screws 13 can be achieved, causing the movable rod 6 to move into the connecting rod 5. The movable rod 6 drives the rack 7 to move, and by utilizing the meshing of the rack 7 and the incomplete gear 9, the movement can be accelerated. The positioning semi-rings 8 on both sides of the connecting rod 5 rotate synchronously and merge to limit the wheat stalks and prevent the wheat from lodging. When it is necessary to adjust the height of the wheat stalk limit according to the growth height of the wheat, the adjusting handle 4-4 can be rotated. The adjusting handle 4-4 drives the composite threaded rod 4-3 to rotate, so that the slider 4-2 slides in the slide groove 16. At the same time, the adjacent connecting rod 4-1 will rotate synchronously in opposite directions to adjust the height of the lifting frame 3. The lifting frame 3 can be raised and lowered by the positioning semi-rings 8 driven by the connecting rod 5, thereby realizing the adjustment of the wheat limit height position by the positioning semi-rings 8.

[0037] Compared with the prior art, the beneficial effects of this utility model are:

[0038] Through the cooperation of connecting rod 5, movable rod 6, rack 7, positioning half ring 8, incomplete gear 9, control rod 10, first bevel gear 11, control handle 12, control screw 13 and second bevel gear 14, not only can it provide support for wheat and prevent wheat from lodging, but the limiting support process is also simple and convenient.

[0039] With the cooperation of the height adjustment mechanism 4, the height of the wheat support can be easily adjusted to adapt to wheat at different growth stages.

[0040] The flexible pad 21 can prevent the wheat stalks from directly and rigidly contacting the positioning semi-ring 8, thus avoiding damage.

[0041] When it rains, rainwater that falls into the slide 16 can be drained through the drainage trough 17, preventing water from accumulating in the slide 16 and affecting the sliding of the slider 4-2.

[0042] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
