Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway detection, in particular to a highway base compaction detection sampling machine. Background Art
[0002] The compaction degree of highway base refers to the ratio of the dry density of the roadbed after compaction to the standard maximum dry density, expressed as a percentage. The compaction standard is based on the highway standard. When the compaction degree is greater than or equal to the specified value, the compaction degree of the assessed road section can get the specified full score. Factors affecting the compaction degree include the nature of the soil, water content, thickness of the compacted soil, strength of the foundation or underlying layer, etc.
[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in the prior art, when sampling the compacted road, workers often sample the road by manually operating a chisel. During this process, the workers have great difficulty in operation and are easily injured during the operation. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a highway base compaction detection sampling machine.
[0005] The above technical objectives of the utility model are achieved through the following technical solutions:
[0006] A highway base compaction detection sampling machine includes a base plate, a support plate with a U-shaped cross section is fixedly arranged on the upper surface of the base plate, a slide plate is slidably arranged on the side walls of the support plate that are close to each other in the vertical direction, a first motor is fixedly arranged on the upper surface of the slide plate, an output shaft end of the first motor passes through the slide plate and extends under the slide plate, a sampling drill bit is installed on the output shaft end of the first motor, and a through hole is opened through the upper surface of the base plate, and the through hole is opposite to the sampling drill bit.
[0007] By adopting the above technical solution, when the staff needs to sample and test the highway, the staff needs to slide the slide plate downwards. During this process, the staff needs to start the first motor, thereby rotating the output shaft of the first motor, so that the sampling drill bit rotates synchronously with the output shaft of the first motor under the action of the output shaft of the first motor. At this time, when the sampling drill bit contacts the ground, a hole is drilled in the ground under the action of the sampling drill bit. Subsequently, when the sampling is completed, the staff can slide the slide plate upwards to remove the sampling drill bit from the ground. At this time, the staff can remove the sample in the sampling drill bit, thereby reducing the difficulty of sampling for the staff.
[0008] Furthermore, a second motor is fixedly provided on the upper surface of the support plate in the horizontal direction, and the output shaft of the second motor passes through the support plate. A threaded rod is fixedly provided on the end of the output shaft of the second motor, and the threaded rod is threadedly connected to the skateboard, and the threaded rod is rotatably connected to the base plate.
[0009] By adopting the above technical solution, when the staff needs to slide the skateboard, the staff needs to start the second motor, thereby rotating the output shaft of the second motor, so that the threaded rod rotates synchronously with the output shaft of the second motor under the action of the output shaft of the second motor, and then the skateboard slides under the action of the threaded rod, thereby reducing the difficulty of sliding the skateboard for the staff, and thereby reducing the difficulty of sampling for the staff.
[0010] Furthermore, a guide hole is formed through the upper surface of the slide plate, a guide rod is slidably arranged in the guide hole, the upper surface of the guide rod is fixed to the bottom surface of the support plate in the horizontal direction, and the bottom surface of the guide rod is fixed to the upper surface of the base plate.
[0011] By adopting the above technical solution, when the slide plate slides, the guide rod and the slide plate slide relative to each other. During this process, the guide rod limits the slide plate, thereby reducing the probability of shaking during the sliding process of the slide plate, thereby reducing the probability of shaking of the sampling drill bit, and thereby improving the stability of the device.
[0012] Furthermore, a connecting rod is fixedly provided at the end of the output shaft of the first motor, a drill connector is threadedly connected to the connecting rod, and the drill connector and the sampling drill bit are fixed to each other.
[0013] By adopting the above technical solution, when the staff needs to replace the sampling drill bit with a different diameter, the staff needs to rotate the sampling drill bit, so that the drill bit connector rotates under the action of the sampling drill bit, so that the drill bit connector and the connecting rod are separated from each other. Afterwards, the staff rotates the drill bit connector to connect the drill bit connector and the connecting rod to each other to complete the installation, thereby improving the practicality of the device.
[0014] Furthermore, a water tank is fixedly provided on the upper surface of the base plate, and a solenoid valve is fixedly provided on the upper surface of the base plate. The water tank and the solenoid valve are connected to each other via a connecting pipe. A hose is installed at one end of the solenoid valve away from the water tank, and the other end of the hose extends into the through hole.
[0015] By adopting the above technical solution, when the sampling drill is in operation, the staff needs to open the solenoid valve, so that the water in the water tank passes through the connecting pipe and the solenoid valve and then sprays out through the hose, thereby cooling the sampling drill, thereby reducing the probability of the sampling drill getting hot during operation.
[0016] Furthermore, a water inlet hopper is installed on the upper surface of the water tank.
[0017] By adopting the above technical solution, the water inlet bucket reduces the difficulty for the staff to add water, thereby reducing the difficulty of the staff's work.
[0018] Furthermore, rollers are distributed in an array on the bottom surface of the bottom plate.
[0019] By adopting the above technical solution, the roller reduces the difficulty for the staff to move the device body, thereby reducing the difficulty of the staff's work.
[0020] In summary, the utility model has the following beneficial effects:
[0021] 1. In this application, when the staff needs to take samples for testing on the highway, the staff needs to slide the slide plate downwards. During this process, the staff needs to start the first motor, thereby rotating the output shaft of the first motor, so that the sampling drill bit rotates synchronously with the output shaft of the first motor under the action of the output shaft of the first motor. At this time, when the sampling drill bit contacts the ground, a hole is drilled in the ground under the action of the sampling drill bit. Then, when the sampling is completed, the staff can slide the slide plate upwards to remove the sampling drill bit from the ground. At this time, the staff can remove the sample in the sampling drill bit, thereby reducing the difficulty of sampling for the staff;
[0022] 2. In the present application, when the staff needs to slide the slide plate, the staff needs to start the second motor, thereby rotating the output shaft of the second motor, so that the threaded rod rotates synchronously with the output shaft of the second motor under the action of the output shaft of the second motor, and then the slide plate slides under the action of the threaded rod, thereby reducing the difficulty of the staff sliding the slide plate, thereby reducing the difficulty of the staff taking samples;
[0023] 3. In the present application, when the slide plate slides, the guide rod and the slide plate slide relative to each other. During this process, the guide rod limits the slide plate, thereby reducing the probability of the slide plate shaking during sliding, thereby reducing the probability of the sampling drill bit shaking, and thereby improving the stability of the device.

DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0029] like Figure 1-3 As shown, the embodiment of the present application discloses a highway base compaction detection sampling machine, including a base plate 1, a support plate 11, a slide plate 12, a first motor 13, a sampling drill 14, a second motor 3, a threaded rod 31, a guide rod 4, a connecting rod 5, a drill connector 51, a water tank 6, a solenoid valve 61, a connecting pipe 62 and a hose 63. The base plate 1 is a rectangular plate-like structure, and a through hole 2 is opened through the upper surface of the base plate 1. The cross section of the support plate 11 is U-shaped, and the support plate 11 is fixedly arranged on the upper surface of the base plate 1. The slide plate 12 is a rectangular plate-like structure, and the two ends of the slide plate 12 are respectively slidably arranged on the side walls of the support plate 11 that are close to each other in the vertical direction. The first motor 13 is fixedly arranged on the upper surface of the slide plate 12, and the axis of its output shaft is vertical. The end of the output shaft of the first motor 13 passes through the slide plate 12 and extends below the slide plate 12. The sampling drill 14 is installed at the end of the output shaft of the first motor 13 for sampling, and the through hole 2 is directly opposite to the sampling drill 14.
[0030] When the staff needs to sample and test the highway, the staff needs to slide the slide plate 12 downwards. During this process, the staff needs to start the first motor 13, thereby rotating the output shaft of the first motor 13, so that the sampling drill bit 14 rotates synchronously with the output shaft of the first motor 13 under the action of the output shaft of the first motor 13. At this time, when the sampling drill bit 14 abuts against the ground, a hole is drilled in the ground under the action of the sampling drill bit 14. Subsequently, when the sampling is completed, the staff can slide the slide plate 12 upwards to remove the sampling drill bit 14 from the ground. At this time, the staff can remove the sample in the sampling drill bit 14, thereby reducing the difficulty of sampling for the staff.
[0031] The second motor 3 is fixedly arranged on the upper surface of the support plate 11 in the horizontal direction, and the axis of its output shaft is vertical, and the output shaft of the second motor 3 passes through the support plate 11. The threaded rod 31 is fixedly arranged at the end of the output shaft of the second motor 3, and its axis coincides with the axis of the output shaft of the second motor 3. The threaded rod 31 is threadedly connected to the slide plate 12, and the threaded rod 31 is rotatably connected to the bottom plate 1.
[0032] When the staff needs to slide the slide plate 12, the staff needs to start the second motor 3, thereby rotating the output shaft of the second motor 3, so that the threaded rod 31 rotates synchronously with the output shaft of the second motor 3 under the action of the output shaft of the second motor 3, and then the slide plate 12 slides under the action of the threaded rod 31, thereby reducing the difficulty of the staff sliding the slide plate 12, and thereby reducing the difficulty of the staff taking samples.
[0033] A guide hole 21 is formed through the upper surface of the slide plate 12. The guide rod 4 is a round rod-shaped structure with a vertical axis. The guide rod 4 is slidably arranged in the guide hole 21. The upper surface of the guide rod 4 is fixed to the bottom surface of the support plate 11 in the horizontal direction, and the bottom surface of the guide rod 4 is fixed to the upper surface of the base plate 1.
[0034] When the slide plate 12 slides, the guide rod 4 and the slide plate 12 slide relative to each other. During this process, the guide rod 4 limits the slide plate 12, thereby reducing the probability of shaking during the sliding process of the slide plate 12, thereby reducing the probability of shaking of the sampling drill bit 14, and thereby improving the stability of the device.
[0035] The connecting rod 5 is fixedly arranged at the end of the output shaft of the first motor 13, and its axis coincides with the axis of the output shaft of the first motor 13. The drill connector 51 is threadedly connected to the connecting rod 5, and the drill connector 51 and the sampling drill bit 14 are fixed to each other.
[0036] When the staff needs to replace the sampling drill bit 14 with a different diameter, the staff needs to rotate the sampling drill bit 14, so that the drill bit connector 51 rotates under the action of the sampling drill bit 14, so that the drill bit connector 51 and the connecting rod 5 are separated from each other. Afterwards, the staff rotates the drill bit connector 51 to connect the drill bit connector 51 and the connecting rod 5 to complete the installation, thereby improving the practicality of the device.
[0037] The water tank 6 is fixedly arranged on the upper surface of the bottom plate 1 for storing water. The solenoid valve 61 is fixedly arranged on the upper surface of the bottom plate 1, and the water tank 6 and the solenoid valve 61 are connected to each other through a connecting pipe 62. The hose 63 is a circular tube structure, one end of the hose 63 is installed at the end of the solenoid valve 61 away from the water tank 6, and the other end of the hose 63 extends into the through hole 2.
[0038] When the sampling drill bit 14 is in operation, the staff needs to open the solenoid valve 61, so that the water in the water tank 6 passes through the connecting pipe 62 and the solenoid valve 61 and then sprays out through the hose 63, thereby cooling the sampling drill bit 14 and reducing the probability of the sampling drill bit 14 getting hot during operation.
[0039] In order to reduce the working difficulty of the staff, a water inlet bucket 7 is installed on the upper surface of the water tank 6. The water inlet bucket 7 reduces the difficulty of the staff to add water, thereby reducing the working difficulty of the staff.
[0040] In order to reduce the difficulty of the work of the staff, rollers 8 are arranged in an array on the bottom surface of the bottom plate 1. The rollers 8 reduce the difficulty of the staff moving the device body, thereby reducing the difficulty of the staff's work.
[0041] The operating principle of the highway base compaction detection sampling machine in this embodiment is:
[0042] When the staff needs to sample and test the highway, the staff needs to start the second motor 3, so that the output shaft of the second motor 3 rotates, so that the threaded rod 31 rotates synchronously with the output shaft of the second motor 3 under the action of the output shaft of the second motor 3, and then the slide plate 12 slides under the action of the threaded rod 31. In this process, the staff needs to start the first motor 13, so that the output shaft of the first motor 13 rotates, so that the sampling drill bit 14 rotates synchronously with the output shaft of the first motor 13 under the action of the output shaft of the first motor 13. At this time, when the sampling drill bit 14 abuts against the ground, the ground is drilled with a hole under the action of the sampling drill bit 14. Subsequently, when the sampling is completed, the staff can slide the slide plate 12 upward to remove the sampling drill bit 14 from the ground. At this time, the staff can remove the sample in the sampling drill bit 14, thereby reducing the difficulty of sampling for the staff.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
