Description

(I) Technical field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a biogas slurry deep application device. (II) Background technology

[0002] With the rapid development of intensive and large-scale livestock and poultry farming, more and more livestock manure and sewage are produced. If they are discharged directly into the environment, it will not only cause serious environmental pollution, but also waste a lot of water and fertilizer resources. Livestock manure and sewage are rich in nitrogen, phosphorus, potassium and a large amount of organic matter. After anaerobic fermentation, biogas slurry is formed. Biogas slurry is a good organic liquid fertilizer. It is odorless after fermentation and the fertilizer efficiency after fermentation is more than 10 times that of ordinary chemical synthetic fertilizers. The organic matter in biogas slurry is easily absorbed by plants, and it will not cause seedling burns due to excessive use like chemical fertilizers. It can replace chemical fertilizers to a certain extent. In developed countries, due to the large amount of arable land per capita, it is convenient to use large-scale biogas slurry deep application equipment. In China, due to the small plots, it is not conducive to the use of large-scale biogas slurry deep application equipment, and the price of large-scale biogas slurry deep application equipment is relatively high. Generally, the way for breeding enterprises to deal with biogas slurry is flooding, which will cause environmental problems such as a large amount of ammonia volatilization and greenhouse gas emissions.

[0015] The beneficial effects of the present invention are:

[0016] 1. Compared with the large-scale biogas slurry deep application device in the prior art, this device has a smaller structure and a width of only about two meters. It is particularly suitable for biogas slurry deep application in smaller plots, which is in line with my country's national conditions of small per capita arable land area.

(V) Specific implementation methods

[0037] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0038] The present invention is a biogas slurry deep application device, including a frame 1, the frame 1 is welded as a whole by square tubes, the front side of the frame 1 is connected to a three-point suspension frame 11 for connecting to traction equipment such as a tractor, the upper rear side of the frame 1 is connected to a liquid storage tank 2, the liquid storage tank 2 stores enough biogas slurry, the size of the liquid storage tank 2 can be changed according to demand, and the upper end of the liquid storage tank 2 is connected to a cover plate to avoid the volatilization and waste of biogas slurry. The front side of the liquid storage tank 2 is provided with a pressurized distribution box 3 whose lower end is connected to the frame 1, and the liquid storage tank 2 is connected to the pressurized distribution box 3 through a pump 21. Specifically, the pump 21 pumps the biogas slurry in the liquid storage tank 2 into the pressurized distribution box 3, and a one-way valve is also connected between the pump 21 and the pressurized distribution box 3 to prevent the biogas slurry from flowing back under pressure.

[0039] A pressurizing device is connected above the pressurized distribution box 3, and the pressurizing device is an air compressor 31. The pressurized distribution box 3 is pressurized by the air compressor 31. A liquid outlet 32 ​​is provided at the bottom of the pressurized distribution box 3. In this embodiment, four liquid outlets 32 are provided. The biogas slurry can be sprayed into the hollow rod 41 from the liquid outlet under pressure to avoid the outlet at the lower end of the hollow rod 41 being blocked by wet soil.

[0040] The frame 1 is connected with a deep application component 4, a ridging component 5 and a pressing component 6 in sequence from front to back.

[0041] The deep application component 4 includes a hollow rod 41 and a plow body 42. The upper end of the hollow rod 41 is connected to the frame 1. Specifically, the hollow rod 41 is provided with a plurality of connection holes 411 in the up-down direction. The connection holes 411 exist in pairs. The frame 1 is connected with a deep application component connection seat 12. The deep application component connection seat 12 is provided with a plurality of pairs of openings corresponding to the paired connection holes 411 in the up-down direction. The hollow rod 41 is connected to the deep application component connection seat 12 through the connection holes 411 and bolts. The hollow rod 41 can adjust the position up and down to achieve the application of biogas slurry at different depths. The top opening of the hollow rod 41 is connected to the liquid outlet 32 ​​through a hose. Specifically, in this embodiment, the hose adopts a corrugated hose, which can be bent arbitrarily, so as to facilitate the adjustment of the deep application depth of the biogas slurry. There are 4 liquid outlets 32, and the number of deep application components 4 is also 4 sets, and they are installed at equal intervals, which is more efficient.

[0042] The lower end of the hollow rod 41 is hingedly connected to the plow body 42. The cross-section of the plow body 42 is crescent-shaped, and a pointed portion is provided at the lower end for easy soil digging. A spring 43 is connected between the plow body 42 and the front side of the hollow rod 41. When the plow body 42 moves forward to dig the soil, the plow body 42 receives the resistance of forward movement and can rotate counterclockwise around the hinge seat at the lower end of the hollow rod 41 by an angle. At the same time, it is blocked by the front side of the hollow rod 41 and cannot continue to rotate backward, and is limited to a better angle for easy soil digging. Figure 7 As shown, during the working process, the spring 43 is always in a stretched state; a liquid outlet cover plate 45 is hinged at the outlet of the lower end of the hollow rod 41, and a plow body connecting rod 44 is hinged at the upper end of the liquid outlet cover plate 45. The end of the plow body connecting rod 44 away from the liquid outlet cover plate 45 is hinged to the upper end of the plow body 42. At this time, the upper end of the plow body 42 moves counterclockwise outward and is pulled to the farthest end outward, which will drive the upper end of the liquid outlet cover plate 45 to move counterclockwise through the plow body connecting rod 44. At this time, the liquid outlet cover plate 45 can open the liquid outlet at the lower end of the hollow rod 41 to ensure the normal release of the biogas slurry. When it is necessary to change ridges, the tractor drives the device to rise. At this time, the tip of the plow body 42 is no longer subjected to force. Under the restoring force of the spring 43, the spring 43 drives the upper end of the plow body 42 to move clockwise, and then pushes the liquid outlet cover plate 45 to move clockwise through the plow body connecting rod 44 to block the liquid outlet at the lower end of the hollow rod 41. At this time, the air compressor 31 stops working to avoid the liquid outlet cover plate 45 from being flushed open.

[0043] The angle between the outlet direction of the lower end of the hollow rod 41 and the forward direction of fertilization is an obtuse angle. In this embodiment, the angle is set to 135 degrees, so that the soil turned up by the plow body 42 is not easy to enter the lower end outlet of the hollow rod 41, ensuring that the soil is at a certain distance from the outlet, further reducing the possibility of blockage.

[0044] The function of the ridging assembly 5 is to backfill the soil after the furrow is plowed out by the plow body 42. The ridging assembly 5 includes a ridging rod 51 whose upper end is connected to the frame 1, and a covering plate 53 is hinged at the lower end of the ridging rod 51. The plow body 42 cuts a furrow of a certain depth on the soil surface, and then the biogas slurry flows into the furrow from the liquid outlet at the lower end of the hollow rod 41, and the soil on both sides of the furrow is pushed into the furrow by the covering plate 53 to cover the biogas slurry. In order to push all the soil on both sides of the furrow into the furrow to achieve better coverage of the biogas slurry, the left and right sides of the lower end of the ridging rod 51 are connected with a ridging plate 52, and the left and right ridging plates 52 are in an eight-shaped shape with a wide front and a narrow back. The soil on both sides of the furrow is gradually accumulated from wide to narrow in the middle between the eight-shaped ridging plates 52, and the middle is a furrow. The soil is pushed into the furrow by the ridging plates 52, and then further leveled by the rear covering plate 53, which has a better covering effect. There are also four sets of ridging components 5 , which correspond one to one with the position of each set of deep application components 4 .

[0045] The lower rear end of the frame 1 is rotatably connected to a rear wheel shaft 71, and both ends of the rear wheel shaft 71 are connected to rear wheels 7. The rolling support of the rear wheels can reduce the burden on the three-point suspension frame 11 connected to the front traction power device, thereby increasing the service life of the three-point suspension frame 11.

[0046] Behind the ridging assembly 5 is a pressing assembly 6. Fig.10 , 11As shown, the suppression assembly 6 includes a driven shaft 74, an active disk 61, a sliding groove block 63 and a sliding block 64. The driven shaft 74 is rotatably connected to the frame 1, specifically through a bearing seat. The active disk 61 is coaxially fixedly connected to the driven shaft 74. The number of active disks 61 is also 4 sets, which are relative to the position of the ridging assembly 5. A suppression link 62 is hinged on the side of the active disk 61, and the end of the suppression link 62 away from the active disk 61 is hinged to the sliding block 64; the sliding groove block 63 is fixedly connected to the frame 1, and a sliding groove in the up and down direction is opened on the sliding groove block 63. The sliding block 64 is slidably connected in the sliding groove, and the lower end of the sliding block 64 A suppression rod 65 is connected, and a suppression plate 66 is connected to the lower end of the suppression rod 65. One end of the driven shaft 74 is connected to a suppression driving group, so that the driven shaft 74 can rotate under the drive of the suppression driving group, and the driven shaft 74 drives the active disk 61 to rotate. A suppression link 62 is hinged on the active disk 61, and the other end of the suppression link 62 is hinged to the sliding block 64, and the sliding block 64 can slide in the sliding groove of the sliding groove block 63. The rotation of the active disk 61 drives the sliding block 64 to move up and down through the suppression link 62, and then drives the suppression plate 66 to move up and down through the suppression rod 65. The suppression plate 66 presses the soil downward to compact the soil above the biogas slurry.

[0047] The above-mentioned suppression drive group includes a driving sprocket 72 and a driven sprocket 73, the driving sprocket 72 is fixedly connected to the rear wheel shaft 71, the driven sprocket 73 is fixedly connected to the driven shaft 74, the driving sprocket 72 and the driven sprocket 73 are connected by a chain, the front traction device drives the device to move forward, the rear wheel 7 is driven to rotate, the rotation of the rear wheel drives the rotation of the rear wheel shaft 71, and then drives the rotation of the driving sprocket 72, the driving sprocket 72 transmits the rotation to the driven sprocket 73 through the chain, the transmission ratio can be set as needed, in this embodiment, the transmission ratio is 5:1, that is, the driving sprocket rotates one circle, the driven sprocket rotates 5 circles, there is a frequency of soil layer suppression, and at the same time, the size of the suppression plate is reasonably set to ensure that the soil layer above the biogas slurry can be suppressed and compacted. In this way, the suppression drive can be achieved by relying only on the rotation of the rear wheel 7, and no redundant power device is required, which is lower in cost and easy to maintain.
