Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering sampling equipment, in particular to a bagged cement sampling device for construction engineering supervision. Background Art

[0002] Project supervision refers to a professional service activity in which a supervision unit with relevant qualifications is entrusted by Party A to monitor Party B's project construction on behalf of Party A. During the construction project supervision process, staff need to use a sampling device to take samples of bagged cement, and then test the cement to supervise the quality of the cement.

[0003] For example, the utility model: "A sampling device for bagged cement for construction engineering supervision", with the announcement number: "CN214471948U", is provided with a sampling cavity, an opening, a limit plate, a push rod, a push plate and a compression spring. After the sampling is completed, it is only necessary to loosen the push plate, so that the sealing plate can quickly seal the opening under the rebound action of the compression spring, thereby facilitating the user's sealing of the opening. However, during the implementation of this patent, the bagged cement directly flows into the sampling cavity through the feed port, which not only easily causes the feed port to be blocked, but also makes it inconvenient for the staff to control the sampling amount. Therefore, the research and development of new bagged cement sampling devices for construction engineering supervision has received more and more attention from researchers. Utility Model Content

[0004] The purpose of the utility model is to provide a bagged cement sampling device for construction engineering supervision, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bagged cement sampling device for construction project supervision, comprising a mounting through-hole, a cement sampling tube and a sampling collection box, a feed port being provided at one end of the top of the cement sampling tube, and a mounting through-hole being provided at the top of the cement sampling tube away from the feed port, a receiving groove being provided at the end of the feed port close to the mounting through-hole, and the receiving groove being connected to the mounting through-hole, a connecting pull rod being installed inside the mounting through-hole, and a connecting pull plate being installed at the end of the connecting pull rod away from the feed port, a sampling collection box being installed at the end of the bottom of the cement sampling tube close to the mounting through-hole, and a collection box cover being installed at the end of the sampling collection box away from the feed port.

[0006] Preferably, a sealing baffle is installed at one end of the connecting rod away from the connecting plate.

[0007] Preferably, a bearing is installed at a middle position of one end of the cement sampling tube close to the sampling and collecting box, and a sampling rotating rod is installed inside the bearing.

[0009] Preferably, a cement guide tube extending into the interior of the cement sampling tube is installed on the top of the sampling and collecting box.

[0010] Preferably, a sampling plug is installed at one end of the cement sampling tube away from the sampling collection box.

[0011] Preferably, a return spring is installed on one end of the connecting pull plate close to the cement sampling tube, and the end of the return spring away from the connecting pull plate is connected to the cement sampling tube.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The bagged cement sampling device for construction engineering supervision is equipped with a bearing, a sampling rotating rod, a spiral feed shaft and a cement sampling tube. During the sampling process, cement enters the cement sampling tube through the feed port. The staff can rotate the sampling rotating rod to make the sampling rotating rod drive the spiral feed shaft to rotate at a constant speed, and the spiral feed shaft can be used to uniformly transport cement. This not only allows the cement to enter the cement sampling tube evenly, avoiding the cement from clogging the feed port, but also helps the staff to control the amount of cement sampling.

[0014] 2. The bagged cement sampling device for construction engineering supervision is equipped with a sampling collection box, a cement guide tube and a collection box cover. During the sampling process, the spiral feed shaft transports cement at a uniform speed and can be transported to the sampling collection box for storage through the cement guide tube, making it easy for workers to take out the cement;

[0015] 3. The bagged cement sampling device for construction project supervision is equipped with a sealing baffle, a connecting pull rod, a connecting pull plate and a reset spring. After the sampling is completed, the elastic action of the reset spring causes it to pull the connecting pull plate, and the connecting pull plate drives the sealing baffle to move together through the connecting pull rod, so that the sealing baffle can block the feed port, thereby preventing cement from continuing to enter the cement sampling tube through the feed port.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3 The utility model provides an embodiment: a bagged cement sampling device for construction engineering supervision, comprising a mounting through hole 6, a cement sampling tube 11 and a sampling collection box 12, a feeding port 3 is provided at one end of the top of the cement sampling tube 11, and a mounting through hole 6 is provided at the top of the cement sampling tube 11 away from the feeding port 3, a receiving groove 4 is provided at the end of the feeding port 3 close to the mounting through hole 6, and the receiving groove 4 is communicated with the mounting through hole 6, a connecting rod 5 is installed inside the mounting through hole 6, and a connecting pull plate 10 is installed at the end of the connecting rod 5 away from the feeding port 3, a sampling collection box 12 is installed at the end of the bottom of the cement sampling tube 11 close to the mounting through hole 6, and a collection box cover 14 is installed at the end of the sampling collection box 12 away from the feeding port 3.

[0022] In this implementation:

[0023] Furthermore, a sealing baffle 2 is installed at one end of the connecting rod 5 away from the connecting plate 10. The sealing baffle 2 blocks the feed port 3, thereby preventing cement from continuing to enter the cement sampling tube 11 through the feed port 3.

[0024] Furthermore, a bearing 7 is installed at a middle position of one end of the cement sampling tube 11 close to the sampling collection box 12, and a sampling rotating rod 8 is installed inside the bearing 7 to facilitate the rotation of the spiral feeding shaft 9.

[0025] Furthermore, the sampling rotating rod 8 passes through the cement sampling tube 11 and extends to the interior of the cement sampling tube 11, and a spiral feeding shaft 9 is installed at one end of the sampling rotating rod 8 close to the feeding port 3. The staff can rotate the sampling rotating rod 8 so that the sampling rotating rod 8 drives the spiral feeding shaft 9 to rotate at a uniform speed, and the cement can be transported at a uniform speed through the spiral feeding shaft 9, which not only allows the cement to enter the interior of the cement sampling tube 11 evenly, avoiding the cement from clogging the feeding port 3, but also helps the staff to control the amount of cement sampling.

[0026] Furthermore, a cement guide tube 13 extending into the cement sampling tube 11 is installed on the top of the sampling and collecting box 12 . The cement in the cement sampling tube 11 can be guided to the sampling and collecting box 12 for storage through the cement guide tube 13 .

[0027] Furthermore, a sampling plug 1 is installed at one end of the cement sampling tube 11 away from the sampling collection box 12, so as to facilitate the insertion of the device into the bagged cement.

[0028] Furthermore, a reset spring 15 is installed at one end of the connecting pull plate 10 close to the cement sampling tube 11, and the end of the reset spring 15 away from the connecting pull plate 10 is connected to the cement sampling tube 11. After the sampling is completed, the staff releases the connecting pull plate 10. At this time, the elastic action of the reset spring 15 pulls the connecting pull plate 10 to move and reset. The connecting pull plate 10 drives the connecting pull rod 5 to move together, and the connecting pull rod 5 drives the sealing baffle 2 to move, so that the sealing baffle 2 can be moved to the inside of the feed port 3, and the feed port 3 can be blocked by the sealing baffle 2 to prevent cement from continuing to enter the cement sampling tube 11 through the feed port 3.

[0029] Working principle:

[0030] When in use, the cement sampling tube 11 can be inserted into the bagged cement through the sampling plug 1. The staff can first pull the connecting pull plate 10, which stretches the reset spring 15, and the connecting pull plate 10 drives the connecting rod 5 to move together, so that the connecting rod 5 pulls the sealing baffle 2 to move, and the sealing baffle 2 can be moved into the receiving groove 4, so that the sealing baffle 2 no longer blocks the feed port 3;

[0031] At this time, cement can enter the cement sampling tube 11 through the feed port 3, and the staff can rotate the spiral feed shaft 9 through the sampling rotating rod 8, so that the spiral feed shaft 9 can uniformly transport the cement inside the cement sampling tube 11 to the position of the cement guide pipe 13, and then guide the cement through the cement guide pipe 13 to the sampling collection box 12 for storage;

[0032] After the sampling is completed, the staff releases the connecting plate 10. At this time, the elastic action of the reset spring 15 causes it to pull the connecting plate 10 to move and reset. The connecting plate 10 drives the connecting rod 5 to move together. The connecting rod 5 drives the sealing baffle 2 to move, so that the sealing baffle 2 can be moved to the inside of the feed port 3. The sealing baffle 2 can block the feed port 3 to prevent cement from continuing to enter the cement sampling tube 11 through the feed port 3;

[0033] Then the staff can open the collecting box cover 14 and take out the cement collected in the sampling collecting box 12 for testing.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
