Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, and in particular to a soil sample collecting device for garden planting. Background Art

[0002] Garden planting requires the assessment of soil fertility and nutrient status. Through soil sample collection, we can understand the nutrient content in the soil, such as key elements such as nitrogen, phosphorus, and potassium, so as to provide a scientific basis for reasonable fertilization and improve crop yield and quality. In addition, we can also evaluate soil pollution and facilitate the adoption of effective control measures. In the process of soil sample collection, it is necessary to take samples at different locations multiple times to ensure the representativeness and collection volume of the samples. In order to control the entire sampling range and improve the representativeness of the samples, the sampling points should be distributed evenly and randomly as much as possible. Commonly used distribution methods include zigzag or serpentine (S-shaped) sampling, which can better overcome the errors caused by agricultural technical measures such as tillage and fertilization. The soil depth and sampling volume of each sampling point should be uniform and consistent. Before analyzing the soil samples, the soil samples need to be placed in an air-drying tray and spread into a thin layer. First, remove the debris in the soil, crush the soil blocks with a wooden stick, and wait for natural air drying and other steps.

[0003] However, the existing soil sample collection equipment has been found to be insufficient during use: for example, when sampling garden soil, since the soil surface is covered with plants, stones and other debris, these debris will be collected along with the soil during the sampling process, and the staff needs to remove these debris, thereby increasing the workload of soil analysis preparation; in addition, after impurities such as plants and stones enter the cylinder, they will be squeezed at the top of the cylinder and occupy space, thereby affecting the amount of soil collected. It is difficult to maintain a consistent amount of soil collected during multiple sampling processes. Therefore, the present application provides a soil sample collection equipment for garden planting to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a soil sample collection device for garden planting to solve the problem that the existing soil collection equipment will collect debris together with the soil when in use, increasing the workload of soil analysis preparation; and that impurities such as plants and stones will be squeezed at the top of the tube and occupy space after entering the tube, thereby affecting the amount of soil collected, and it is difficult to maintain a consistent amount of soil collected during multiple sampling processes.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A soil sample collection device for garden planting, comprising a support rod and a fixed handle, wherein the bottom end of the support rod is fixedly connected to a fixed plate and a first sampling cylinder, the peripheral side wall of the support rod is slidably connected to a sleeve, one end of the sleeve is fixedly connected to a movable handle, and the other end of the sleeve is fixedly connected to a push plate sliding in the first sampling cylinder; it also includes a separation component installed on the fixed plate, the separation component includes a second sampling cylinder rotatably connected to the first sampling cylinder, after the soil is inserted into the second sampling cylinder and the first sampling cylinder, the separation component is controlled to separate the soil in the second sampling cylinder and the first sampling cylinder, and at the same time the push plate pushes out the soil in the first sampling cylinder.

[0006] The cam is an assembly made of a plurality of gears, each of which is adapted to engage a first gear and a second gear of the plurality of gears, each of which is adapted to engage a second gear of the plurality of gears.

[0007] Optionally, a detachable shell is installed on the top of the fixed disk, and a fixed block is fixedly connected to the top of the shell. A slot is provided in the fixed block, and a detachable spiral spring is installed in the slot; a slot is provided at the top of the rotating rod, and the inner end of the spiral spring is inserted into the slot for fixation.

[0008] Optionally, a fixed ring body is fixedly connected between the sleeve and the connecting rod, a connecting channel connected to the fixed ring body is opened in the connecting rod, and a water outlet is opened at one end of the connecting channel away from the fixed ring body; a plurality of fixing strips are fixedly connected to the peripheral side wall of the push plate, and a push ring is commonly fixedly connected to one end of the plurality of fixing strips away from the push plate, and the push ring is in contact with the inner walls of the first sampling cylinder and the second sampling cylinder.

[0009] Optionally, the moving handle is a hollow structure, and an elastic water bag is installed in the hollow structure. The bottom end of the moving handle is provided with a through slot connected to the hollow structure, and a pressing handle is hingedly connected; the top end of the pressing handle is fixedly connected with an extrusion plate matching the size of the through slot.

[0010] Optionally, a water pipe is fixedly connected to the outer wall of the fixed ring body, and one end of the water pipe away from the fixed ring body is inserted into the movable handle and connected to the elastic water bag. The elastic water bag is also provided with a water inlet, and a switch valve is provided on the water pipe. The straight groove, the curved groove and the sliding column are all arc-shaped structures.

[0011] Optionally, the plurality of fixing bars are arranged in a circular array with the push plate as the center, there are at least two water outlets, and the two water outlets are symmetrically arranged with the push plate as the center, and the center of the push plate gradually inclines toward the bottom wall; a pedal of an integral structure is fixedly connected to the bottom end of the shell, and the pedal is located above the first sampling cylinder and the second sampling cylinder.

[0012] Optionally, the bottom widths of the fixing strip and the push ring are greater than the top widths of the fixing strip and the push ring, and the tops of the fixing strip and the push ring are both inclined structures.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a separation component, the soil can be automatically separated when the first sampling barrel on the support rod is rotated, thereby preventing debris from being collected together with the soil, which increases the workload of soil analysis preparation; by separating the soil, the amount of retained soil collection is made consistent; and when the first sampling barrel is rotated, the upper layer of soil can be automatically pushed out, which is convenient for operation.

[0014] By setting a volute spring, when the rotation of the rotating rod is controlled, the volute spring will gradually tighten; when the pressure on the rotating rod stops, the volute spring will gradually relax and drive the rotating rod back to its original position. Therefore, after the pressure on the support rod stops, the push plate and the support rod will automatically reset without manual reset, thereby further simplifying the operation process of soil separation.

[0015] By providing an elastic water bag and a connecting channel, the push plate and the push ring are repeatedly pushed and pulled to slide in the two sampling tubes for scrubbing, thereby ensuring that the sampling tubes are cleaned in time, thereby preventing the problem of affecting the collection volume if the residual samples in the sampling tubes are not completely removed during multiple sampling at different positions, thereby further facilitating the soil collection work; in addition, if the soil at the sampling position is relatively dry, the above structure can also moisten the sampling position, making it easier for the sampling tube to be inserted into the dry soil for sampling.

[0025] like Figures 1 to 16 As shown, an embodiment of the present invention provides a soil sample collection device for garden planting, including a support rod 1 and a fixed handle 2, the bottom end of the support rod 1 is fixedly connected to a fixed disk 3 and a first sampling tube 4, the side wall of the support rod 1 is slidably connected to a sleeve 34, one end of the sleeve 34 is fixedly connected to a moving handle 28, and the other end of the sleeve 34 is fixedly connected to a push plate 22 sliding in the first sampling tube 4; it also includes a separation component installed on the fixed disk 3, the separation component includes a second sampling tube 5 rotatably connected to the first sampling tube 4, after the soil is inserted into the second sampling tube 5 and the first sampling tube 4, the separation component is controlled to separate the soil in the second sampling tube 5 and the first sampling tube 4, and at the same time, the push plate 22 pushes the soil in the first sampling tube 4.

[0026] like Figures 1 to 9As shown, the separation assembly includes a first stop column 6 fixedly connected to the outer peripheral side wall of the second sampling tube 5, and a second stop column 8 fixedly connected to the outer peripheral side wall of the first sampling tube 4, and a fixed rod 7 rotatably connected to the first stop column 6 is fixedly connected to the second stop column 8; a fixed seat 10 is fixedly connected to the top of the fixed disk 3, and a rotating rod 11 is rotatably connected in the fixed seat 10, and the rotating rod 11 and the peripheral side walls of the fixed rod 7 are respectively fixedly connected to the second gear 12 and the first gear 9; a linear groove 14 and a curved groove 15 are opened on the peripheral side wall of the rotating rod 11, and the curved groove 15 is arranged around the peripheral side wall of the rotating rod 11, and the top ends of the linear groove 14 and the curved groove 15 are in a connected state; a connecting rod 13 that passes through the fixed disk 3 is fixedly connected between the sleeve 34 and the push plate 22, and the connecting rod 13 drives the push plate 22 to slide in the first sampling tube 4, and the peripheral side wall of the connecting rod 13 is fixedly connected The sliding column 16 is slidably matched with the straight groove 14 and the curved groove 15, and the sliding column 16 is close to the top of the connecting rod 13; in the default state, the first sampling tube 4 and the second sampling tube 5 are in a combined state, and the first sampling tube 4 and the second sampling tube 5 are aligned. When in use, the first sampling tube 4 and the second sampling tube 5 in the combined state are inserted into the soil, so that the soil is filled in the two sampling tubes, and the sampling tubes are directly pulled out; by pushing the moving handle 28 downward, the sleeve 34 drives the push plate 22 to move in the two sampling tubes, and the complete sample can be taken out; when the upper layer of soil needs to be taken out, the first sampling tube 4 and the second sampling tube 5 in the combined state are inserted into the soil, so that the soil is filled in the two sampling tubes, and the support rod 1 is rotated by controlling the fixed handle 2 to make the support rod 1 as a whole drive the first sampling tube 4 to move an angle. Since the two sampling tubes are staggered at an angle, the upper and lower layers of the soil are separated.

[0027] By providing the connecting rod 13 and the curved groove 15 and the straight groove 14 opened on the rotating rod 11, since the second sampling tube 5 is inserted into the soil and fixed by the first blocking column 6, the second sampling tube 5 is kept in a stable state. When the support rod 1 is rotated, the fixed plate 3 rotates around the fixed rod 7, and the rotating rod 11 on the fixed plate 3 rotates through the meshing of the first gear 9 and the second gear 12. In this process, the curved groove 15 on the rotating rod 11 guides the sliding column 16 to move, so that the sliding column 16 pushes the connecting rod 13 to move along the curved groove 15, thereby prompting the connecting rod 13 to move downward. Therefore, when the first sampling tube 4 is rotated, the connecting rod 13 will drive the push plate 22 to move downward, thereby pushing out the upper soil; when the sleeve 34 is pushed downward directly by the moving handle 28, the rotating rod 11 will not rotate at this time, and the sliding column 16 on the connecting rod 13 slides in the straight groove 14, thereby not interfering with the connecting rod 13. Therefore, when the sampling tube is rotated, the soil can be automatically pushed out without additional operation steps, and the use process is convenient and quick.

[0028] In addition, the first stop column 6 and the second stop column 8 are both designed as inclined structures. When the first sampling tube 4 and the second sampling tube 5 are combined together, the first stop column 6 is aligned with the second stop column 8. In this combined state, when the sampling tube is inserted into the soil, the inclined structure helps the tube body to break the soil; at the same time, when the first sampling tube 4 is rotated, the first stop column 6 plays a limiting role to prevent the problem of the second sampling tube 5 rotating when the first sampling tube 4 is rotated.

[0029] like Figure 5 , Figure 8 As shown, a detachable shell 17 is installed on the top of the fixed disk 3, and a fixing block 19 is fixedly connected to the top of the shell 17. A card slot is opened in the fixing block 19, and a detachable spiral spring 20 is installed in the card slot; a slot 21 is opened at the top of the rotating rod 11, and the inner end of the spiral spring 20 is inserted into the slot 21 for fixing. By setting the spiral spring 20, its outer end is fixed in the card slot, and its inner end is fixed in the slot 21 at the top of the rotating rod 11. When the rotation of the rotating rod 11 is controlled, the spiral spring 20 will gradually tighten; and when the pressure on the rotating rod 11 is stopped, the spiral spring 20 will gradually relax and drive the rotating rod 11 back to its original position. Therefore, after the rotation of the supporting rod 1 is controlled to drive the push plate 22 to push the soil out, after the pressure on the supporting rod 1 is stopped, the push plate 22 and the supporting rod 1 will automatically reset, without manual reset, thereby simplifying the operation process of soil separation.

[0030] like Fig. 9 , Fig.10 As shown, a fixed ring body 26 is fixedly connected between the sleeve 34 and the connecting rod 13, a connecting channel 24 connected to the fixed ring body 26 is provided in the connecting rod 13, and a water outlet 25 is provided at one end of the connecting channel 24 away from the fixed ring body 26; a plurality of fixing strips 23 are fixedly connected to the side wall of the push plate 22, and a push ring 35 is fixedly connected to one end of the plurality of fixing strips 23 away from the push plate 22, and the push ring 35 contacts the inner wall of the first sampling tube 4 and the second sampling tube 5; the moving handle 28 is a hollow structure, and an elastic water bag 29 is installed in the hollow structure, and a water bag 29 is provided at the bottom of the moving handle 28 and connected to the hollow structure A through groove 30 is connected to each other, and a pressing handle 31 is hingedly connected; an extrusion plate 32 matching the size of the through groove 30 is fixedly connected to the top of the pressing handle 31, a water pipe 27 is fixedly connected to the outer wall of the fixed ring body 26, and the end of the water pipe 27 away from the fixed ring body 26 is inserted into the movable handle 28 and connected to the elastic water bag 29. The elastic water bag 29 is also provided with a water filling port, and a cover is provided on the water filling port. A switch valve 33 is provided on the water pipe 27. The switch valve 33 is a prior art, and the switch valve 33 is controlled as needed to achieve the connected or closed state of the water pipe 27; the size and capacity of the elastic water bag 29 are set according to needs.

[0031] By setting a connecting channel 24 in the connecting rod 13, the connection between the connecting rod 13, the water pipe 27 and the fixed ring body 26 is achieved; by setting an elastic water bag 29 in the moving handle 28, when the current sampling work is completed, by pressing the pressing handle 31 on the moving handle 28, the squeezing plate 32 will apply pressure to the elastic water bag 29. In this process, the water in the elastic water bag 29 flows into the two sampling tubes through the connecting channel 24 and the water outlet 25. Subsequently, by repeatedly pushing and pulling the moving handle 28, the push plate 22 and the push ring 35 slide in the two sampling tubes to scrub, ensuring that the sampling tubes are cleaned in time, thereby preventing the problem of affecting the collection volume if the residual samples in the sampling tubes are not completely removed when sampling at different positions for multiple times; in addition, if the soil at the sampling position is relatively dry, the above structure can also wet the sampling position to facilitate the insertion of the sampling tube into the dry soil for sampling.

[0032] like Fig. 9 As shown, the plurality of fixing bars 23 are arranged in a circular array with the push plate 22 as the center, there are at least two water outlets 25, and the two water outlets 25 are symmetrically arranged with the push plate 22 as the center, and the center of the push plate 22 gradually tilts toward the bottom wall; since the water outlets 25 are symmetrically arranged, when water is discharged, the water flow can be evenly sprayed into the sampling chamber through these symmetrical water outlets 25, thereby improving the uniformity of the water spray; in addition, if the water outlet 25 is blocked by mud, the mud blocking the water outlet 25 can be squeezed out by continuously pressing the elastic water bag 29 to apply pressure.

[0033] like Fig. 9 As shown, the bottom width of the fixing strip 23 and the push ring 35 is greater than the top width of the fixing strip 23 and the push ring 35, and the tops of the fixing strip 23 and the push ring 35 are both inclined structures. By setting the upper ends of the fixing strip 23 and the push ring 35 as inclined structures, and the upper end of the push plate 22 gradually tilts toward the surroundings, when the push plate 22 moves in the sampling tube for cleaning, the inclined structure helps the gray water to flow down and reduce the accumulation of gray water; because the lower end width of the fixing strip 23 and the push ring 35 is greater than the upper end width, and the plurality of fixing strips 23 are arranged in a circular array, when the push plate 22 pushes the soil, the plurality of fixing strips 23 can increase the contact area with the soil, which not only maintains the purpose of easy cleaning, but also facilitates the pushing out of the soil.

[0034] The straight groove 14, the curved groove 15 and the sliding column 16 are all arc-shaped structures.

[0035] like Figure 3 As shown, a pedal 18 of an integrated structure is fixedly connected to the bottom end of the shell 17, and the pedal 18 is located above the first sampling cylinder 4 and the second sampling cylinder 5. The shell 17 and the pedal 18 are arranged as an integrated structure, which facilitates assembly.

[0036] The working principle of the technical solution provided by the present invention is as follows: whether to separate the top layer of soil is selected according to the soil debris situation. When complete sampling is performed, the first sampling tube 4 and the second sampling tube 5 in the combined state are inserted into the soil so that the soil is filled in the two sampling tubes. The sampling tube is directly pulled out, and the moving handle 28 is pushed downward, so that the sleeve 34 drives the push plate 22 to push out the complete soil sample in the sampling tube.

[0037] When the upper soil layer needs to be separated, the first sampling tube 4 and the second sampling tube 5 in the combined state are inserted into the soil so that the soil is filled in the two sampling tubes. At this time, the support rod 1 is rotated by controlling the fixing handle 2 to make the fixing plate 3 rotate around the fixing rod 7. Since the two sampling tubes are staggered at an angle, the upper and lower layers of the soil are separated. At the same time, the rotating rod 11 on the fixing plate 3 rotates through the engagement of the first gear 9 and the second gear 12. During this process, the curved groove 15 on the rotating rod 11 guides the sliding column 16 to move, so that the sliding column 16 pushes the connecting rod 13 to move along the curved groove 15, prompting the connecting rod 13 to move downward. Therefore, while rotating the first sampling tube 4, the connecting rod 13 will drive the push plate 22 to move downward and push out the upper soil. When the sampling tube is reset, the separated soil sample is taken out by the push plate 22.

[0038] After the soil sampling work at the current position is completed, by pressing the pressing handle 31 on the moving handle 28, the squeezing plate 32 will apply pressure to the elastic water bag 29. During this process, the water in the elastic water bag 29 flows into the two sampling tubes through the connecting channel 24 and the water outlet 25. Subsequently, by repeatedly pushing and pulling the moving handle 28, the push plate 22 and the push ring 35 slide in the two sampling tubes for brushing, ensuring that the sampling tubes are cleaned in time, thereby preventing the problem of affecting the collection volume if the residual samples in the sampling tubes are not completely removed when sampling at different positions for multiple times.

[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
