On the rear end of the tongue cavity, and the front end of the locking head 251 is set as an inclined surface, the rear end of the first guide rail 2 is provided with a motor 27, on which a wire wheel 271 is arranged, and the wire wheel 271 is a double-groove wire wheel, the rear end of the pulling member 25 is provided with one end of a pull rope 26, and the other end is arranged on the wire wheel 271, the rear ends of the left and right connecting members 25 are provided with pull ropes 26, and one end of the left and right pull ropes 26 are arranged on the wire wheel 271, and the pull rope 26 is sleeved with a first elastic member 28, and its two ends are respectively in contact with the end face of the pulling member 25 and the rear end face of the second slide 291.
[0025] The motor 27 rotates to drive the wire wheel 271 to rotate, thereby tightening the pull rope 26, thereby driving the pulling member 25 to move backward, compressing the first elastic member 28 during the backward movement, and when the motor 27 is powered off, the pulling member 25 is restored to its initial state forward under the action of the first elastic member 28.
[0026] The sample box 3 is slidably arranged in the first slide 29, and the front end of the locking head 251 is located in the first slide 29. Therefore, when the pulling member 25 moves backward, the rear end face of the locking head 251 touches the front end face of the sample box 3, and the pulling member 25 moves backward, driving the sample box 3 to move backward together.
[0027] The sample box 3 includes a frame 31, and three sample chambers 311 are arranged in the frame 31. A sliding bottom surface 32 is slidably arranged in each sample chamber 311, wherein a screw rod 33 is arranged at the lower end of the middle one of the three sliding bottom surfaces 32, and guide rods are arranged at the lower ends of the other two, and the lower ends are arranged on the bottom plate together. A threaded sleeve 34 is rotatably arranged on the lower end wall of the middle sample chamber 311, and the threaded sleeve 34 is connected with the threaded sleeve 33, and the threaded sleeve 34 rotates to drive the threaded sleeve 33 to rise or fall. A first gear 35 is arranged on the side of the frame 31, and the frame 31 is also provided with a first gear 35. The transmission device 36 includes a first bevel gear 361 and a second bevel gear 362. The first bevel gear 361 is meshed with the second bevel gear 362. The first bevel gear 361 is provided with a first belt groove 363, and the silk sleeve 34 is provided with a second belt groove 341. The two are connected by a belt. The second bevel gear 362 is provided with a third belt groove 364, and the first gear 35 is provided with a fourth belt groove 351. The two are connected by a belt, so that the first gear 35 rotates to drive the silk sleeve 34 to rotate, thereby realizing the rise or fall of the sliding bottom surface 32.
[0028] The sliding bottom surface 32 is provided with grooves around it, and a smear ring 321 is arranged in the groove. The smear ring 321 is a sponge, and its elasticity contacts the inner wall of the sample retention cavity 311. A cavity is provided in the sliding bottom surface 32, and a demoulding liquid is arranged in the cavity. The cavity is connected with the smear ring 321, and the demoulding liquid in the cavity can flow out into the smear ring 321. A rack 21 is arranged on the first guide rail 2.
[0029] A coating roller 24 is also provided on the first guide rail 2 and is located in front of the rack 21 . A cavity is provided in the coating roller 24 and a demoulding liquid is provided in the cavity. The demoulding liquid inside can penetrate to the surface so that the surface of the coating roller 24 has the demoulding liquid.
[0030] The sample box 3 is moved backward under the action of the pulling member 25, and first passes through the coating roller 24. The surface of the coating roller 24 and the upper plane of the sliding bottom surface 32 on the sample box 3 touch each other, so that the upper plane of the sliding bottom surface 32 is coated with the demoulding liquid. After the upper planes of the three sliding bottom surfaces 32 all pass through the coating roller 24, the first gear 35 on the sample box 3 meshes with the rack 21, and the sample box 3 continues to move backward, so that the first gear 35 rotates, so that the sliding bottom surface 32 moves downward, and the coating ring 321 on the sliding bottom surface 32 coats the demoulding liquid on the four walls of the sample cavity 311. When the sliding bottom surface 32 moves to the bottom, the first gear 35 is disengaged from the rack 21. At this point, the four walls of the sample cavity 311 and the upper plane of the sliding bottom surface 32 are coated with the demoulding liquid, so that the surfaces in contact with the concrete are coated with the demoulding liquid.
[0031] A limiting block 22 is provided at the rear end of the first guide rail 2, and three sample openings 11 are opened on the concrete flow channel 1. When the sample box 3 touches the limiting block 22, the three sample cavities 311 on the sample box 3 are aligned with the three sample openings 11 on the concrete flow channel 1. At the same time, a trigger switch 12 is provided around each sample opening 11 in the concrete flow channel 1, and a pressure switch 23 is provided at the front end of the limiting block 22. When the sample box 3 touches the limiting block 22, it presses on the pressure switch 23, and the pressure switch 23 controls the motor 27 to cut off the power and controls the trigger switch 12 to be powered on. When the stones in the concrete flowing through the concrete flow channel 1 hit the trigger switch 12 at the same time, the three sample openings 11 are controlled to open at the same time, so that the concrete in the concrete flow channel 1 flows into the three sample cavities 311. After the sample opening 11 is opened for a certain period of time, it is automatically closed. At this point, an automatic random sampling is completed.
[0032] Its working principle or usage is as follows:
[0033] In the initial state, the sliding bottom surface 32 on the sample box 3 is flush with the upper plane of the sample box 3, and a storage box with a previous sample box 3 automatically drops a sample box 3 to the front end of the first guide rail 2, or a sample box 3 is manually placed at the front end of the first track 2. A flow counter is provided in the concrete flow channel 1. When the flow in the concrete flow channel 1 accumulates to a certain value, the motor 27 is automatically started to tighten the rope 28, driving the pulling member 25 to move backward.
[0034] The initial position of the sample box 3 is behind the pulling member 25. Therefore, when the pulling member 25 moves backward, the rear end face of the locking head 251 on it touches the front end face of the sample box 3, driving the sample box 3 to move backward together. It first passes through the coating roller 24. The surface of the coating roller 24 and the upper plane of the sliding bottom surface 32 on the sample box 3 touch each other, so that the upper plane of the sliding bottom surface 32 is coated with the demoulding liquid. After all the upper planes of the three sliding bottom surfaces 32 pass through the coating roller 24, the upper surface of the sample box 3 The first gear 35 is meshed with the rack 21, and the sample box 3 continues to move backward, so that the first gear 35 rotates, so that the sliding bottom surface 32 moves downward, and the smearing circle 321 on the sliding bottom surface 32 smears the demoulding liquid on the four walls of the sample cavity 311. When the sliding bottom surface 32 moves to the bottom, the first gear 35 is disengaged from the rack 21. At this point, the four walls of the sample cavity 311 and the upper plane of the sliding bottom surface 32 are all coated with the demoulding liquid, so that the surfaces in contact with the concrete are all coated with the demoulding liquid.
[0035] The pulling member 25 continues to press the sample box 3 to move backward until the sample box 3 touches the limit block 22. At this time, the three sample cavities 311 on the sample box 3 are aligned with the three sample openings 11 on the concrete flow channel 1. At the same time, the sample box 3 presses on the pressure switch 23, thereby controlling the motor 27 to cut off the power and controlling the trigger switch 12 to be powered on. When the stones in the concrete flowing through the concrete flow channel 1 hit the trigger switch 12 at the same time, the three sample openings 11 are controlled to open at the same time, so that the concrete in the concrete flow channel 1 flows into the three sample cavities 311. The samples sampled in this way are random samples, and the operator cannot manually control the sampling, making the samples more representative.
[0036] After the sample retaining opening 11 is opened for a certain period of time, it is automatically closed. At this time, the sample box 3 filled with concrete samples can be taken away manually or the limit under the first guide rail 2 can be automatically opened to allow the sample box 3 to automatically flow into the next automatic storage process.
[0037] When the motor 27 is powered off, the pulling member 25 moves forward to the front end under the action of the first elastic member 28 to prepare for the next automatic sampling.
[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
