The sampling device realizes the preliminary screening of samples by manually repeatedly pulling the mesh frame and cooperating with elastic force to realize the up and down vibration of the mesh frame. However, in actual use, the user needs to pull the sample and the mesh frame upward, which is labor-intensive. For this reason, the utility model proposes a soil survey sample on-site preparation device. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a soil survey sample on-site preparation device, which performs preliminary screening of the obtained soil samples by introducing an inclined screening plate. After the samples fall onto the screening plate in the first area, the samples with larger particles that do not pass through the mesh holes automatically roll to the second area under the action of gravity, thereby conveniently completing the preliminary screening and separation of the samples, saving time and effort.

[0004] The soil survey sample on-site preparation device in this scheme includes a U-shaped frame, a partition is connected inside the U-shaped frame to separate it into a first area and a second area, and a through hole connecting the first area and the second area is opened on the partition, and a tray is connected in the first area of ​​the U-shaped frame, wherein an inclined sieve plate is arranged above the tray, and the lowest edge of the surface of the sieve plate extends to the through hole, so that the samples that have not passed through the sieve plate are transported to the second area inclined toward the through hole, and the sieve plate is connected to the tray and / or the partition.

[0005] The technical solution further defined in the utility model is:

[0006] Furthermore, a vibration motor is provided on the U-shaped frame or the partition, and the vibration motor is connected to the tray. The vibration motor drives the tray to vibrate, thereby preventing the soil samples dropped from the screening plate from accumulating.

[0007] Furthermore, sliders are provided at both ends of the tray, and sliding grooves for accommodating the sliders are provided on the opposite inner walls of the U-shaped frame, and the height of the sliding grooves is greater than the height of the sliders, so that the tray vibrates mainly in the vertical direction.

[0008] Furthermore, a vertical supporting spring is connected between the bottom of the tray and the U-shaped frame.

[0009] Furthermore, the screening disc comprises a frame-shaped screening plate and a screening mesh arranged at the center thereof.

[0010] Furthermore, a servo motor is connected to the bottom of the tray, and an output end of the servo motor extends to the top surface of the tray and is connected to a stirring rod to slightly stir the soil sample in the tray in a horizontal direction.

[0011] Furthermore, an electric heating plate is connected to the bottom of the tray to heat and dry the soil sample on the tray.

[0012] Furthermore, a baffle lower than the through hole is provided in the second area of ​​the U-shaped frame, and the baffle is connected to the partition and / or the side wall of the U-shaped frame, wherein the inner edge of the baffle is closely attached to the partition, and the height of the outer edge is not higher than the inner edge.

[0013] Furthermore, the U-shaped frame is also connected to a handle.

[0014] Furthermore, the screening plate is connected to the top of the tray via a support rod.

[0015] The beneficial effects of the utility model are as follows: the utility model divides the designed U-shaped frame into a first area and a second area, and performs preliminary screening on the obtained soil samples by introducing an inclined screening plate. After the samples fall onto the screening plate in the first area, samples with larger particles that do not pass through the mesh holes automatically roll down to the second area under the action of gravity, thereby conveniently completing the preliminary screening and separation of the samples, saving time and effort, and reducing labor intensity; at the same time, the vibration motor can drive the tray and the screening plate to oscillate, thereby improving screening efficiency, and cooperating with stirring and heating to realize drying treatment during the up and down oscillation process of the soil samples after screening, thereby facilitating subsequent detection of the soil samples, and being suitable for on-site preparation of soil survey samples.

[0021] like Figure 1 As shown, it is a schematic diagram of the structure of the soil survey sample field preparation device provided in this embodiment, including a U-shaped frame 1, a partition 3 is connected to the middle of the U-shaped frame 1, and the U-shaped frame 1 is divided into a first area and a second area. The partition 3 is provided with a square through hole 4 for connecting the first area and the second area. The two opposite outer side walls of the U-shaped frame 1 are connected with U-shaped handles 2 for easy extraction and transportation of the device.

[0022] See also Figure 1-2 Specifically, in the first area, four support springs 8 are connected to the U-shaped frame 1, and the support springs 8 are connected to the tray 6. The side wall of the partition 3 is connected to the vibration motor 13. The upper part of the vibration motor 13 is connected to the tray 6 through the U-shaped plate 14 and the electric heating plate 11 to drive the tray 6 to vibrate. Figure 4 As shown, both sides of the tray 6 in this embodiment are connected to sliders 18, which are inserted into the slide groove 17 on the inner wall of the U-shaped frame 1. The width of the slide groove 17 is equal to that of the slider 18, but the height of the slide groove 17 is much greater than the slider 18, so that when the vibration motor 13 drives the tray 6 to vibrate, the tray 6 mainly vibrates in the vertical direction. Of course, in some other implementations, the width of the slide groove 17 can also be greater than the width of the slider 18, so that the tray 6 can also perform a certain amplitude of oscillation in the horizontal direction.

[0023] The tray 6 in this embodiment is connected to the inclined screening plate 5 through four support rods 7. The screening plate 5 is in the shape of a square frame, and a screening net 10 is installed in the center to form a screening disk. The inner edge of the inclined screening disk is inclined downward toward the through hole 4, so that the debris or lumps that fail to pass through the screening net 10 roll down to the second area through the through hole 4. It should be noted that the screening plate 5 in this embodiment is directly connected to the vibrating tray 6, and vibrates with the tray 6 to screen the soil sample. In some other embodiments, the screening plate 5 can also be hinged on the partition 3 on one side and hinged on the outer side of the tray 6 through the support rod 7 on the tray 6 on the other side, so that when the tray 6 vibrates, the two outer support rods 7 on the tray 6 drive the screening plate 5 to deflect to complete the screening process.

[0024] Specifically, a servo motor 12 is also provided in the U-shaped plate 14 , and the output end of the servo motor 12 extends to the top surface of the tray 6 and is connected to the stirring rod 9 . The servo motor 12 described in this embodiment is a small motor with a reducer, which can slightly stir the screened samples in the tray 6 after being turned on.

[0025] See also Figure 3 In this embodiment, a horizontal baffle 16 is connected to the second area, and the screened samples fall onto the baffle 16 through the through hole 4. In some other embodiments, the outer side of the baffle 16 can be tilted downward to directly discharge the screened samples from the device. At the same time, a battery 15 is also installed in the second area, which can be connected to the vibration motor 13 and the servo motor 12 to provide power.

[0026] When this embodiment is in use, after the vibration motor 13 is turned on, the tray 6 and the sieve plate vibrate in the vertical direction, and the sampled soil is poured onto the sieve net 10 in the first area for preliminary screening. Small particles of soil fall into the tray 6 through the mesh of the sieve net 10, and large particles of soil agglomerates and stones roll down the sieve net 10 and fall onto the baffle 16 in the second area through the through hole 4. The soil sample falling into the tray 6 is then stirred and heated to form a preliminary sample, thereby realizing the preliminary on-site preparation of soil survey samples.

[0027] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
