DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Please see attached Figure 1 - Figure 7The embodiment of the present invention provides a sample grinding device suitable for soil detection, including a body 1, three grinding shells 301 are installed on the top of the body 1, a processing box 501 is installed on the side of the grinding shell 301, an electric guide rail is installed on one side of the processing box 501, a support frame 502 is installed on the outside of the electric guide rail through an electric slider, an electric telescopic rod is installed on the top of the support frame 502, and a slitting blade is fixedly connected to the output end of the electric telescopic rod, a heating box 202 is installed on the outside of the body 1, a heating wire is installed inside the heating box 202, a blower 201 is installed on the outside of the heating box 202, a connecting pipe 203 is connected to the through hole on the top of the heating box 202, an air jet pipe 205 is installed at the end of the connecting pipe 203, and a plurality of nozzles are installed on the outer surface of the air jet pipe 205.

[0020] Specifically, the grinding shell 301 is located at the top of the machine body 1, and there are three grinding shells 301. These shells are used to accommodate soil samples and grind them. When in use, the soil sample is placed in the grinding shell 301 and then processed by mechanical action. The grinding shell 301 can ensure the uniformity and stability of the sample during the soil grinding process.

[0021] The processing box 501 is located on the side of the grinding shell 301, and plays the role of preliminary drying, curing and processing of soil samples. The contact between the hot air flow formed by the heated air and the soil sample causes the moisture on the sample surface to evaporate quickly, and makes the soil particle size more uniform, providing a more stable and uniform sample for the subsequent grinding steps. The cooperation of the electric guide rail and the electric slider enables the support frame 502 to move precisely along the guide rail. The electric telescopic rod installed on the top of the support frame 502 can adjust the height, thereby controlling the range of motion of the slitting blade connected thereto. The function of the slitting blade is to cut the soil sample and effectively distinguish the material distribution and composition of the soil at different depth levels.

[0022] The heating box 202 is installed on the outside of the machine body 1, and a heating wire is provided inside to heat the air passing through the heating box 202. The blower 201 is installed outside the heating box 202, and is responsible for sucking in the external air and guiding it to flow into the heating box 202. The air is heated by the heating wire to form a hot air flow, which is transported to the jet pipe 205 through the connecting pipe 203. Its operating principle is as follows: Initial drying and curing of soil samples The collected soil sample is placed in the processing box 501. At this time, the starter motor drives the transmission shaft 602 to rotate, and the transmission shaft 602 drives the plurality of bevel gears 1 603 to rotate, and then drives the bevel gear 2 604 to rotate through meshing. The bevel gear 2 604 then drives the reciprocating screw to rotate, and the rotation of the reciprocating screw drives the jet tube 205 to move synchronously. In this process, the electric telescopic rod drives the cutting blade to cut the soil sample, thereby helping to dry and process the soil sample more evenly.

[0023] Hot air drying of soil samples The blower 201 is started, and the outside air enters the heating box 202. The air is heated by the electric heating wire in the heating box 202 to form a hot air flow. The hot air flow is transmitted to the air jet pipe 205 through the connecting pipe 203, and is evenly sprayed onto the soil sample in the processing box 501 through multiple nozzles. As the air jet pipe 205 moves back and forth, the hot air flow covers the soil sample, ensuring that the soil sample is quickly and evenly dried and solidified. This process effectively removes moisture from the soil, avoiding the expansion and adhesion of wet soil during grinding and subsequent processing, thereby ensuring that the soil sample maintains a stable and uniform physical state during grinding.

[0024] A hydraulic cylinder 1 303 is installed on the outside of the machine body 1, and a connecting frame 304 is fixedly connected to the output end of the hydraulic cylinder 1 303, and a driving plate 307 is fixedly connected to the end of the connecting frame 304. Two arc grooves 305 are provided on the outer surface of the grinding shell 301, and a grinding wheel 302 is installed inside the grinding shell 301 through a driving shaft 308. An arc filter 306 is installed on the inner side of the grinding shell 301, and the outer surface of the grinding wheel 302 fits the outer side of the arc filter 306. A slide groove is provided inside the driving plate 307, and the end of the driving shaft 308 is arranged inside the slide groove.

[0025] Specifically, a hydraulic cylinder 303 is installed on the outside of the machine body 1. When the hydraulic cylinder 303 is working, the back and forth contraction effect generated at its output end drives the connecting frame 304 to move, and then the driving plate 307 also moves accordingly. Through the hydraulic drive system, a large power output can be achieved, and the driving process is stable and efficient.

[0026] The connecting frame 304 is fixedly connected to the output end of the hydraulic cylinder 303 through one end thereof, and is connected to the driving plate 307 at the other end. The function of the connecting frame 304 is to convert the linear motion output by the hydraulic cylinder into the synchronous movement of the driving plate 307. A slide groove is provided inside the driving plate 307, and the function of the slide groove is to guide the driving shaft 308 to move along a predetermined trajectory. Through the movement of the driving shaft 308, the grinding wheel 302 can move along the inner surface of the grinding shell 301. Due to the synchronous movement of the driving shaft 308 and the driving plate 307, the grinding wheel 302 can move along the outer surface of the arc filter 306 during the entire working process. The outer surface of the grinding wheel 302 fits the outer side of the arc filter 306, and the cooperation between the two can play a good role in the grinding process. The grinding wheel 302 is in close contact with the arc filter 306, which effectively ensures that the soil material is uniformly stressed during the grinding process, thereby improving the efficiency and effect of soil grinding. An arc filter 306 is installed inside the grinding shell 301. The design of the filter can effectively filter out the soil particles that have been ground, and prevent the unground soil particles from remaining in the grinding shell 301. In addition, the cooperation between the arc filter 306 and the grinding wheel 302 also makes the grinding process more efficient. During the grinding process, the contact between the grinding wheel 302 and the arc filter 306 can generate good physical friction, effectively completing the crushing and grinding of soil particles. Its working principle is as follows: When the hydraulic cylinder 303 is started, the reciprocating movement generated by the output end of the hydraulic cylinder is transmitted to the driving plate 307 through the connecting frame 304. Since a chute is provided inside the driving plate 307 and the end of the driving shaft 308 is arranged in the chute, the movement of the driving plate 307 causes the driving shaft 308 to move synchronously along the inner wall of the arc groove 305. The driving shaft 308 drives the rotation of the grinding wheel 302, thereby realizing the movement of the grinding wheel 302 along the outer surface of the arc filter 306, and then grinding the soil. During the grinding process, the grinding wheel 302 is in close contact with the arc filter 306, ensuring the material screening and grinding effect during the grinding process. At the same time, the design of the arc groove 305 ensures that the grinding wheel 302 can move accurately along the predetermined trajectory, avoiding instability during the movement process, and further improving the grinding effect.

[0027] The outer side of the driving plate 307 is fixedly connected with a connecting rod 401, the outer side of the grinding shell 301 is hinged with a plurality of knocking rods 402 through a rotating shaft, the end of the knocking rod 402 is fixedly connected with a knocking ball 404, the outer side of the grinding shell 301 is fixedly connected with a knocking plate 403, and the outer side of the grinding shell 301 is fixedly connected with a plurality of knocking plates 403. A movable groove is provided on the inner side of the knocking rod 402, and a movable block is slidably connected inside the movable groove, and the outer side of the movable block is rotatably connected with one end of the connecting rod 401.

[0028] Specifically, when the driving plate 307 moves, the movable block is driven to move synchronously along the inner wall of the movable groove through the connecting rod 401. The movement of the driving plate 307 is directly transmitted to the connecting rod 401, and the connecting rod 401 drives the knocking rod 402 to swing through the movable block at its end.

[0029] The end of the knocking rod 402 is fixedly connected with a knocking ball 404. Through the swing of the knocking rod 402, the knocking ball 404 will continuously knock the knocking plate 403 fixed on the outside of the grinding shell 301. The impact force generated by the knocking action of the knocking ball 404 causes the knocking plate 403 to vibrate, and is further transmitted to the arc filter 306. This vibration can vibrate away impurities or particulate matter accumulated on the arc filter 306, thereby preventing the arc filter 306 from being blocked.

[0030] The knocking plate 403 is fixedly connected to the outside of the grinding shell 301 through multiple connections to form a certain support surface. When the knocking ball 404 knocks, the knocking plate 403 will be stressed and start to vibrate. This vibration not only acts on the filter screen, further helping to remove the sediment on the curved filter screen 306, but also evenly distributes the transmission of force to ensure the efficiency and uniformity of the vibration.

[0031] The existence of the movable groove enables the movable block to slide freely in the knock rod 402 along with the movement of the connecting rod 401, thereby ensuring that the swing of the knock rod 402 can maintain an accurate trajectory. The outer side of the movable block is rotatably connected to one end of the connecting rod 401, ensuring effective cooperation and precise movement between the two components.

[0032] When the driving plate 307 moves, it drives the connecting rod 401 to move synchronously. The connecting rod 401 is connected to the movable block, and drives the movable block to slide along the groove wall through the inner wall of the movable groove. The movement of the movable block drives the knocking rod 402 to swing, and the swing of the knocking rod 402 produces a continuous knocking action through the hinge action of the rotating shaft, and the knocking ball 404 hits the knocking plate 403, thereby generating vibration. Through this mechanism, the vibration can be effectively transmitted to the arc filter 306, preventing impurities on the filter from accumulating and maintaining the smooth operation of the entire device.

[0033] Two mounting blocks 204 are installed on the outside of the processing box 501, and a reciprocating screw is rotatably installed between the two mounting blocks 204. The outside of the reciprocating screw is threadedly connected with a threaded block, and the top of the threaded block is fixedly connected to the outside of the air injection pipe 205. A transmission shaft 602 is rotatably installed on the front side of the processing box 501, and a motor for rotating the transmission shaft 602 is installed on the outside of the processing box 501. A plurality of bevel gears 1 603 are fixedly connected to the outside of the transmission shaft 602, and a plurality of bevel gears 2 604 are meshedly connected to the outside of the bevel gear 1 603, and the bevel gear 2 604 is fixedly connected to one end of the reciprocating screw.

[0034] Specifically, after the motor is started, the drive shaft 602 connected thereto is driven to rotate. The rotation of the drive shaft 602 is transmitted to the bevel gear 2 604 through a plurality of bevel gears 1 603 fixed thereon. Due to the connection between the bevel gear 2 604 and the reciprocating screw, the rotation of the bevel gear 2 604 directly causes the rotation of the reciprocating screw.

[0035] An electric telescopic rod is installed at the bottom of the grinding shell 301, and a rotating door is rotatably installed at the output end of the electric telescopic rod. A hydraulic cylinder 601 is installed on the side of the grinding shell 301, and a push plate is fixedly connected to the output end of the hydraulic cylinder 601.

[0036] Specifically, the electric telescopic rod at the bottom of the grinding shell 301 is started, which drives the rotating door to swing. At this time, the hydraulic cylinder 1 303 is started to drive the push plate to move, so that the layered soil falls into the grinding shell 301 for grinding.

[0037] Working principle: The specific use of this device includes the following steps: Step 1: Place the excavated soil sample in the processing box 501, and start the motor outside the processing box 501. The motor drives the transmission shaft 602 to rotate, and the rotation of the transmission shaft 602 drives the multiple bevel gears 1 603 to rotate. The bevel gear 1 603 drives the meshed bevel gear 2 604 to rotate, and the bevel gear 2 604 drives the reciprocating screw to rotate, thereby driving the air injection tube 205 to move synchronously; Step 2: Start the blower 201 to let the outside air enter the heating box 202. The air is heated by the electric heating wire inside the heating box 202 to form a hot air flow. The hot air flow is transmitted to the inside of the jet pipe 205 under the transportation effect of the connecting pipe 203, and finally sprayed out through multiple nozzles to spray the hot air flow on the soil sample located inside the processing box 501. With the reciprocating movement of 503, the soil sample is quickly dried and solidified to avoid the expansion and adhesion of the wet soil during grinding and subsequent processing, thereby ensuring the stability and uniformity of the soil sample. Step 3: The support frame 502 is moved to the designated position by the cooperation of the electric guide rail and the electric slider. At this time, the electric telescopic rod outside the support frame 502 is started. The movement of the output end of the electric telescopic rod drives the slitting blade to move downward to slice the soil into layers. Through the precise soil slicing operation, each part of the sample will be fully processed and homogenized, thereby ensuring the representativeness of the final sample; Step 4: Start the electric telescopic rod at the bottom of the grinding shell 301, which drives the rotating door to swing. At this time, start the hydraulic cylinder 1 303 to drive the push plate to move, and the layered soil falls into the grinding shell 301 for grinding. Step 5: Start the hydraulic cylinder 303, and use the back and forth contraction of the output end of the hydraulic cylinder 303 to drive the connecting frame 304 to move synchronously. When the connecting frame 304 moves, it drives the driving plate 307 to move synchronously. Since the ends of the driving shaft 308 are sequentially arranged inside the arc groove 305 and the driving plate 307, when the driving plate 307 moves, the driving shaft 308 moves along the inner wall of the arc groove 305, so that the grinding wheel 302 moves along the outer surface of the arc filter 306 to grind the soil; Step six, when the driving plate 307 moves, it drives the connecting rod 401 to move synchronously. At this time, the connecting rod 401 drives the movable block to move along the inner wall of the movable groove, so that the knocking rod 402 swings under the action of the rotating shaft, and the knocking ball 404 continuously knocks on the knocking plate 403, causing vibration to the arc filter 306 to prevent the arc filter 306 from being blocked, thereby ensuring the smooth operation of the entire device.
