Abstract
Description
Technical Field
[0001] The invention relates to the technical field of soil crushing experimental testing, in particular to a driving rake soil crushing experimental testing device. Background Art
[0002] The driven harrow soil crushing test device is a professional equipment used to evaluate the soil crushing performance of the driven harrow. The driven harrow is mainly used in the agricultural field to crush and level the soil during arable land operations. The test device can accurately measure various parameters of the driven harrow in the soil crushing process, such as the degree of soil crushing, soil particle distribution, soil crushing depth, etc., thereby providing a scientific basis for the performance evaluation, optimal design and quality inspection of the driven harrow.
[0003] Even soil collected in the same test area may have local differences in texture. In a field, there may be areas with high clay content and areas with high sand content. This makes it difficult to ensure that the soil texture is exactly the same for each test when filling the soil box. This difference will affect the evaluation of the soil crushing effect of the driven harrow, because soils of different textures have different resistance to the driven harrow and the way they are crushed. Summary of the invention
[0004] The object of the present invention is to provide a test device for a driven harrow soil crushing test to solve the problem raised in the above-mentioned background technology that even if the soil is collected in the same test area, its texture may have local differences. In a piece of farmland, there may be areas with a high clay content and parts with a high sand content. This makes it difficult to ensure that the soil texture is exactly the same in each test when filling the soil box. This difference will affect the evaluation of the soil crushing effect of the driven harrow, because soils of different textures have different resistance to the driven harrow and the way they are crushed. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a driving rake soil crushing test device, comprising a fixed base frame, a plurality of digging rake nails are fixedly connected to the bottom of the fixed base frame, and the digging rake nails are distributed in a linear array at the bottom of the fixed base frame; a plurality of collecting boxes are fixedly connected to the bottom of the fixed base frame, and the collecting boxes are distributed in a linear array at the bottom of the fixed base frame, one side of each of the digging rake nails is fixedly connected to a collecting box, and a collecting trough is provided inside each of the collecting boxes; a water storage box is fixedly connected to the top of the fixed base frame, a water outlet is provided on one side of the water storage box, and a movable piston is movably connected to the inside of the water outlet, and a user needs to use it by holding a connecting roller, and at the same time, the user uses the connecting roller by holding a connecting roller. The roller drives the digging rake nails to dig soil and crush stones. When soil sampling is carried out after the soil gravel is crushed, the texture of the soil collected in the same test area may also have local differences. In a piece of farmland, there may be areas with high clay content and parts with high sand content. This makes it difficult to ensure that the soil texture is exactly the same for each test when filling the soil box. This difference will affect the evaluation of the driving rake's soil crushing effect, because soils of different textures have different resistance and crushing methods to the driving rake. Therefore, a collection box is provided on one side of each digging rake nail, and soil samples are collected through the collection slot in the collection box, thereby ensuring that data such as soil crushing degree and particle size distribution can be accurately collected during the test.
[0005] Further preferably, a connecting frame is fixedly connected inside the fixed base frame, a limiting plate is fixedly connected to one side of the connecting frame, the limiting plate is located on the back side of the fixed base frame, and a fixed base plate is fixedly connected to the top of the other side of the connecting frame.
[0006] Further preferably, a mounting base is fixedly connected to the top of the fixed bottom plate, and a connecting roller is fixedly connected to the top of the mounting base.
[0007] Further preferably, a through groove is provided inside the connecting roller, and the inside of the through groove is movably connected to a hinge shaft via a hinge.
[0008] Further preferably, the side surface of the articulated shaft is movably connected with an articulated rod through a hinge, and the articulated rod is movably connected to the inside of the through groove. When sampling soil in some deep pits, it is inconvenient for workers to go up and down. At this time, the articulated rod is rotated out by rotating the articulated shaft, thereby extending the strength of the connecting roller, which can make it more convenient to sample the soil inside the deep pit. The operation of the manual drive rake is relatively simple, and the operator does not need to have complex professional technical knowledge. The soil crushing test can be carried out by pushing the drive rake forward and other operations.
[0009] Further preferably, the top of the connecting roller is fixedly connected to a limited top plate, and a bottom section of the side surface of the hinged rod is fixedly connected to a fixed baffle through a sleeve connection. For some non-professional researchers or beginners, it is a testing tool that is very easy to master. At the same time, the operator can observe the dynamic process of soil crushing in real time during the soil crushing process, including the turning and crushing of soil particles and the distribution of debris in the soil.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] In the present invention, the user needs to use the hand-held connecting roller to drive the digging rake nails downward to dig soil and gravel through the hand-held connecting roller. When soil sampling is carried out after the soil gravel is crushed, the texture of the soil collected in the same test area may also have local differences. In a piece of farmland, there may be areas with high clay content and parts with high sand content. This makes it difficult to ensure that the soil texture of each test is exactly the same when filling the soil box. This difference will affect the evaluation of the driving rake's soil crushing effect, because soils of different textures have different resistance and crushing methods to the driving rake, so that a collection box is provided on one side of each digging rake nail, and soil samples are collected through the collection slot in the collection box, thereby ensuring that during the test, data such as soil crushing degree and particle size distribution can be accurately collected.
[0012] In the present invention, when sampling soil in some deep pits, it is inconvenient for workers to go up and down. At this time, the hinge shaft is rotated to make the hinge rod rotate out, thereby extending the strength of the connecting roller, which can make it more convenient to sample the soil inside the deep pit. The operation of the manual drive rake is relatively simple, and the operator does not need to have complex professional technical knowledge. The soil crushing test can be carried out by pushing the drive rake forward and other operations. For some non-professional researchers or beginners, it is a test tool that is very easy to master. At the same time, the operator can observe the dynamic process of soil crushing in real time during the soil crushing process, including the turning and crushing of soil particles and the distribution of debris in the soil.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.
[0021] See also Figure 1-Figure 6The present invention provides a technical solution: a driving rake soil crushing test device, comprising a fixed base frame 1, a plurality of digging rake nails 2 are fixedly connected to the bottom of the fixed base frame 1, the digging rake nails 2 are distributed in a linear array at the bottom of the fixed base frame 1, a plurality of collecting boxes 3 are fixedly connected to the bottom of the fixed base frame 1, the collecting boxes 3 are distributed in a linear array at the bottom of the fixed base frame 1, one side of each digging rake nail 2 is fixedly connected to a collecting box 3, each collecting box 3 is provided with a collecting trough 4 inside, a water storage box 5 is fixedly connected to the top of the fixed base frame 1, a water outlet 7 is provided on one side of the water storage box 5, and a movable piston 6 is movably connected to the water outlet 7. The user needs to use it by holding a connecting roller 12, and at the same time, the digging is driven by the connecting roller 12. The soil rake nails 2 dig downward to break the soil and gravel. When soil sampling is carried out after the soil gravel is broken, the texture of the soil collected in the same test area may also have local differences. In a piece of farmland, there may be areas with high clay content and parts with high sand content. This makes it difficult to ensure that the soil texture is exactly the same for each test when filling the soil box. This difference will affect the evaluation of the driving rake's soil crushing effect, because soils of different textures have different resistance and crushing methods to the driving rake. Therefore, a collection box 3 is provided on one side of each digging rake nail 2, and soil samples are collected through the collection slot 4 in the collection box 3, thereby ensuring that during the test, data such as soil crushing degree and particle size distribution can be accurately collected.
[0022] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a connecting frame 8 is fixedly connected to the interior of the fixed base frame 1, a limiting plate 9 is fixedly connected to one side of the connecting frame 8, the limiting plate 9 is located on the back of the fixed base frame 1, a fixed base plate 10 is fixedly connected to the top of the other side of the connecting frame 8, a mounting base 11 is fixedly connected to the top of the fixed base plate 10, a connecting roller 12 is fixedly connected to the top of the mounting base 11, a through groove 13 is opened inside the connecting roller 12, and a hinge shaft 14 is movably connected to the inside of the through groove 13 through a hinge.
[0023] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the side surface of the articulated shaft 14 is movably connected with an articulated rod 15 through a hinge, and the articulated rod 15 is movably connected to the inside of the through groove 13. The top of the connecting roller 12 is fixedly connected to a limited top plate 16, and the bottom side surface of the articulated rod 15 is fixedly connected to a fixed baffle 17 through a sleeve. When sampling soil in some deep pits, it is inconvenient for the staff to go up and down. At this time, the articulated shaft 14 is rotated to make the articulated rod 15 rotate out, thereby extending the strength of the connecting roller 12, which can make it more convenient to sample the soil inside the deep pit. The operation of the manual drive rake is relatively simple, and the operator does not need to have complex professional technical knowledge. The soil crushing test can be carried out by pushing the drive rake forward. For some non-professional researchers or beginners, it is a very easy to master test tool. At the same time, the operator can observe the dynamic process of soil crushing in real time during the soil crushing process, including the turning and crushing of soil particles and the distribution of debris in the soil.
[0024] The use method and advantages of the present invention: When the driving harrow soil crushing test device is used, the working process is as follows:
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when using the driven rake soil crushing test device, the user needs to use it through the hand-held connecting roller 12, and at the same time drive the digging rake nail 2 downward to dig soil and crush stones through the hand-held connecting roller 12. When soil sampling is carried out after the soil gravel is crushed, the texture of the soil collected in the same test area may also have local differences. In a piece of farmland, there may be areas with high clay content and parts with high sand content. This makes it difficult to ensure that the soil texture of each test is exactly the same when filling the soil box. This difference will affect the evaluation of the driven rake soil crushing effect, because soils of different textures have different resistance and crushing methods to the driven rake, so that a collection box 3 is provided on one side of each digging rake nail 2, and the soil samples are collected through the collection groove 4 in the collection box 3. The manual driving rake is relatively simple to operate, and does not require the operator to have complex professional technical knowledge. The soil crushing test can be carried out by pushing the driving rake forward and other operations. For some non-professional researchers or beginners, it is a very easy-to-master test tool. At the same time, the operator can observe the dynamic process of soil crushing in real time during the soil crushing process, including the turning and crushing of soil particles and the distribution of debris in the soil.
