Description

Technical Field

[0001] The invention relates to the technical field of seeding punchers, and in particular to a film-covered seeding puncher for rapeseed field experiments. Background Art

[0002] Rapeseed is an annual or biennial herbaceous crop belonging to the family Cruciferae and the genus Brassica. The European rapeseed has an upright stem with branches, and only the young leaves have a few scattered bristles; the middle and upper leaves change from oblong elliptical to lanceolate; the flowers are corymbose, the sepals are ovate, and the petals are light yellow; the fruits are linear and poisonous; the seeds are spherical, yellow-brown, and often black near the hilum. The flowering period is from March to April, and the fruiting period is from April to May. It is named after its origin in Europe. European rapeseed is native to Europe, but wild germplasm resources of European rapeseed have not been found in the wild. It is widely planted in various parts of China and cultivated all over the world. After many generations of reproduction, multiple varieties with different characteristics that adapt to different growth conditions have been hybridized. It is not easy to survive in areas with little rainfall and drought in spring. The main method of reproduction of European rapeseed is self-pollination and sexual reproduction. European rapeseed has beautiful bright yellow flowers and can also be used as an ornamental plant; it is one of the important sources of seed vegetable oil, and seed oil is also used to make lubricants, greases, varnishes, varnishes, soaps, resins, nylons, plastics, insect repellents, stabilizers and medicines. Planting European rapeseed in saline-alkali wasteland with reasonable fertilization measures will have great economic value and ecological benefits, which will help improve the quality of saline-alkali soil and promote the virtuous cycle of the ecological environment of saline-alkali wasteland. Film mulching cultivation is to cover the ground with transparent plastic film, sow seeds under the film and protect the growth of crop seedlings; after the temperature warms up, the film is uncovered to allow the seedlings to grow under normal climatic conditions. Plastic film is used in large quantities in agriculture, and the problem of farmland pollution caused by its waste has attracted increasing attention. Because polyethylene or polyvinyl chloride in plastic residues contains toxic substances, it is harmful to livestock and poultry as well as soil microorganisms. In the 1990s, scientists have successfully used agricultural and sideline products as raw materials to make agricultural degradable films or starch films, in which herbicides and various nutrients are also added. The covering agricultural film is degraded by microorganisms and gradually seeps into the soil as crops grow and the temperature rises, which not only completely solves the problem of soil pollution, but also becomes a weed control agent and a source of nutrients for the roots to absorb.

[0003] Rapeseed mulching sowing can withstand severe cold. The mulching has a good thermal insulation effect, which can keep the growth environment of the seeds at a stable temperature and promote the growth of the seeds. In rapeseed field experiments, the rapeseed field needs to be covered with film first, and then the film is perforated before sowing. Existing punchers usually use a circular punching head for punching, but due to the large area of ​​the circular holes, the evaporation at the punching site is increased, and the film is prone to wrinkling, displacement or tearing during the punching process, which reduces the service life of the film and has poor practicality. Now there is an urgent need for a rapeseed field trial mulching sowing puncher to solve the above problems. Summary of the invention

A moving seat 52 is arranged on the inner side of the frame 1, and a first hydraulic drive rod 53 is embedded inside the moving seat 52. Driving pump 51, a first hydraulic driving rod 53 is installed on the lower end surface of the first hydraulic driving pump 51, a connecting seat 54 is arranged below the first hydraulic driving rod 53, a cutting head 55 is installed on the lower end surface of the movable seat 52, a threaded adjusting rod 56 is rotatably arranged on the inner side of the frame 1, the auxiliary compaction assembly 6 includes a second hydraulic driving pump 61, a second hydraulic driving rod 63, a connecting plate 64, a fixed seat 65 and a pressing seat 66, a second hydraulic driving pump 61 is installed on the inner side of the frame 1, a second hydraulic driving rod 63 is installed on the lower end of the second hydraulic driving pump 61, a connecting plate 64 is arranged below the second hydraulic driving rod 63, a fixed seat 65 is arranged below the connecting plate 64, and a pressing seat 66 is arranged below the fixed seat 65.

[0030] In the present embodiment, in the present embodiment, there are three groups of movable seats 52, and the movable seats 52 slide closely along the inner side surface of the frame 1. The frame 1 can preliminarily limit the moving trajectory of the movable seat 52. A positioning plate 521 is provided on the rear end face of the movable seat 52, and a threaded adjustment seat 522 is embedded on the upper end face of the positioning plate 521. The threaded adjustment seat 522 and the threaded adjustment rod 56 are meshed with each other. The rotation of the threaded adjustment rod 56 can drive the positioning plate 521 to move radially along the threaded adjustment rod 56 through the threaded adjustment seat 522, and the positioning plate 521 can drive the movable seat 52 to move together. This design can drive the positioning plate 521 and the movable seat 52 to move in the vertical direction by rotating the threaded adjustment seat 522, thereby changing the height of the movable seat 52 and the positioning plate 521, thereby achieving the purpose of adjusting the cutting depth of the cutting head 55.

[0031] In this embodiment, a turning handle 57 is welded to the upper end of the threaded adjustment rod 56. The turning handle 57 allows the user to rotate the threaded adjustment rod 56 more conveniently and labor-savingly, thereby achieving the purpose of quickly adjusting the height of the movable seat 52.

The positioning plate 521 slides tightly along the outer side of the positioning block 524 through the positioning grooves 523. The design of the positioning block 524 and the positioning grooves 523 can limit the moving trajectory of the positioning plate 521. This design makes the movement of the positioning plate 521 more stable, thereby playing an auxiliary limiting effect on the moving seat 52.

[0033] In this embodiment, the cutting head 55 is in a cross shape. The cross-shaped cutting head 55 will automatically close at the ground film after cutting. Compared with circular hole cutting, the evaporation at the cutting point will be reduced, which is conducive to better growth of rapeseed. The upper end surface of the connecting seat 54 is fixedly connected to the extended end of the first hydraulic drive rod 53. The extended end of the first hydraulic drive rod 53 can drive the connecting seat 54 to move together, thereby adjusting the position of the connecting seat 54 and the cutting head 55, so as to achieve the function of the cutting head 55 descending for cutting and ascending for retraction. The first hydraulic drive pump 51 is connected to the first hydraulic drive rod 53 through a hydraulic pipeline. The first hydraulic drive pump 51 can control the extension or retraction of the first hydraulic drive rod 53. The first hydraulic drive pump 51 is electrically connected to the control panel 4 through a wire, and the control panel 4 can control the opening and closing of the first hydraulic drive pump 51.

[0034] In this embodiment, a fixing frame 62 is welded to the front end surface of the frame 1, and the second hydraulic drive pump 61 is fixedly connected to the frame 1 through the fixing frame 62. The fixing frame 62 can fix the position between the second hydraulic drive pump 61 and the frame 1. The second hydraulic drive pump 61 is electrically connected to the control panel 4 through a wire. The control panel 4 can control the opening and closing of the second hydraulic drive pump 61. The second hydraulic drive rod 63 is connected to the second hydraulic drive pump 61 through a hydraulic wire pipe. The extended end of the second hydraulic drive rod 63 is fixedly connected to the upper end surface of the connecting plate 64. The second hydraulic drive pump 61 can control the extension or retraction of the second hydraulic drive rod 63, thereby adjusting the position of the connecting plate 64.

[0035] In this embodiment, a limiting hole 651 is provided on the upper end surface of the fixing seat 65, and a limiting rod 67 is provided on the upper end surface of the pressing seat 66. The limiting rod 67 passes through the fixing seat 65 through the limiting hole 651. The design of the limiting hole 651 and the limiting rod 67 enables a movable connection between the fixing seat 65 and the pressing seat 66, and can make the movement of the pressing seat 66 relative to the fixing seat 65 more stable. The annular side surface of the limiting rod 67 is sleeved with an extrusion spring 68, which can provide a downward elastic force. The pressing seat 66 is provided with three specifications. The upper end surface of the pressing seat 66 is provided with a cutting groove 661, and the cutting groove 661 corresponds to the cutting head 55. The cutting groove 661 facilitates the cutting head 55 to cut the ground film below. There are three groups of fixed seats 65 with equal specifications. The first ends of the three groups of fixed seats 65 are fixedly connected by connecting plates 64. The other end of the fixed seat 65 is provided with a support rod 69. The support rod 69 is slidably connected to the frame 1 through a through hole. The design of the support rod 69 makes the fixed seat 65 more stable when moving together, thereby facilitating the pressing seat 66 to compact the ground film.

[0036] Working principle:

[0037] The user pushes the frame 1 to move by the push rod 3 and the moving wheel 2. After moving to the appropriate position, the user operates the control panel 4 to control the start of the lower knife cutting program. The second hydraulic drive pump 61 is turned on first, and drives the second hydraulic drive rod 63 to extend downward. The extended end of the second hydraulic drive rod 63 drives the connecting plate 64 to move, and the connecting plate 64 drives the fixing seat 65 and the pressing seat 66 to move downward together. The pressing seat 66 first contacts the ground, and then the pressing seat 66 continuously approaches the fixing seat 65 under the action of the downward pressure, and compresses the extrusion spring 68. Under the elastic force of the extrusion spring 68, the pressing seat 66 presses and fixes the ground film. This design can stabilize the position of the ground film during cutting, thereby avoiding the cutting head 55 The cutting causes wrinkles, displacement or tearing at the bottom, and then the first hydraulic drive pump 51 is turned on, and the first hydraulic drive pump 51 drives the first hydraulic drive rod 53 to extend downward, and the extended end of the first hydraulic drive rod 53 drives the connecting seat 54 to move together, and the connecting seat 54 drives the cutting head 55 to move downward, and the cutting head 55 passes through the cutting groove 661 and the pressing seat 66 to cut the ground film. After the cutting is completed, the first hydraulic drive rod 53 drives the connecting seat 54 and the cutting head 55 to reset and retract. Since the cutting head 55 is in a cross shape, this design makes the bottom after cutting have a smaller opening area, and the ground film will automatically close after cutting, thereby reducing the evaporation at the cutting point, which is more conducive to the growth of rapeseed.
