Description

Technical Field

[0001] The utility model relates to the technical field of mortar sampling, in particular to a novel mortar sampling machine. Background Art

[0002] Mortar is a viscous substance mixed with water, cement, sand and other additives. It is used to bond and fill the gaps between building materials, such as bricks and stones. Mortar is often used in construction projects to fix and connect masonry structures, and plays a role in reinforcement and waterproofing. Depending on the required engineering environment, the formula and use of mortar will also vary.

[0003] During the production process of mortar, in order to conduct quality inspection and ensure the quality of construction, it is usually necessary to use sampling equipment to sample the mortar. The existing mortar sampling method usually uses a cylindrical steel pipe, which is inserted into the mortar mixture and then lifted by hand to take the mortar out of the pipe for laboratory testing. In this way, the amount of extracted mortar cannot be controlled. If the amount is too large, it will lead to waste of mortar materials and increase production costs. On the contrary, if the sampling amount is too small, it may not meet the needs of experimental testing and affect quality control.

[0004] Therefore, a new type of mortar sampling machine is proposed to solve the above problems. Utility Model Content

[0025] In this embodiment, Figure 1-4 A new type of mortar sampling machine is given. The utility model comprises a vertically arranged cylinder 1. The top of the cylinder 1 is rotatably connected to a transmission shaft 2 which penetrates into the interior and extends downward. The transmission shaft 2 is provided with a spiral blade 3. A sampling box 4 is provided above the right side of the cylinder 1. A feed port 5 is provided at the upper end of the left side of the sampling box 4.

A disassembly mechanism is provided for the cylinder 1 and the sampling box 4. A telescopic plate 8 is horizontally provided inside the sampling box 4. A shifting mechanism is provided between the sampling box 4 and the telescopic plate 8.

[0026] In this embodiment, the transmission shaft 2 is rotated to drive the spiral blade 3 to rotate. In this process, an axial propulsion force is generated along the transmission shaft 2, and the mortar is transported to the cylinder 1, and then discharged into the sampling box 4 from the discharge hopper 6. At the same time, the telescopic plate 8 is driven to move by the shifting mechanism to control the amount of mortar stored in the sampling box 4, so as to quantitatively extract the mortar. The sampling box 4 can be disassembled by the convenient disassembly mechanism for testing. At the same time, the discharge hopper 6 leaks out, and if it is extracted later, a large amount of mortar can be extracted.

[0027] Preferably, as another embodiment of the utility model, the easy disassembly mechanism includes a rectangular groove 71, a spring 72, a connecting plate 73, a concave groove 74, a disc 75, a rectangular block 76 and a round rod 77. A connecting plate 73 with one end extending to the right is provided on the front and rear sides of the cylinder 1. The sampling box 4 is located between the two connecting plates 73. A plurality of vertically distributed concave grooves 74 connected to the outside are provided on the front and rear sides of the left side of the sampling box 4. Rectangular grooves 71 are provided on the opposite sides of the front and rear concave grooves 74. Rectangular blocks 76 are provided inside the front and rear rectangular grooves 71. Round rods 77 penetrating the connecting plate 73 on the same side are provided on the opposite sides of the front and rear rectangular blocks 76. A disc 75 is provided at one end of the connecting plate 73. A spring 72 whose two ends are connected to the outside of the disc 75 and the outside of the connecting plate 73 is sleeved on the round rod 77. Press plates 10 are vertically provided on the opposite sides of the two connecting plates 73. The outsides of the press plates 10 are connected to the disc 75 on the same side.

[0028] It should be noted that the spring 72 is in a state of storing force, and pressing the buttons 10 on both sides can drive the disc 75 and the round rod 77 to move toward the middle. In this process, the extrusion between the disc 75 and the connecting plate 73 further compresses the spring 72, and the disc 75 drives the rectangular block 76 to leave the rectangular groove 71 on the sampling box 4. At this time, the fixation of the sampling box 4 has been completed, and by pulling it outward, the rectangular block 76 can be moved out along the concave groove 74, and then the sampling box 4 can be removed.

[0029] Preferably, as another embodiment of the utility model, the shifting mechanism includes a threaded shaft 91, a frame 92 and a threaded through hole 93. The bottom of the sampling box 4 is provided with a concave-shaped frame 92, and the bottom of the frame 92 is provided with a threaded through hole 93. The bottom of the telescopic plate 8 is rotatably connected with a threaded shaft 91 that penetrates to the bottom of the sampling box 4 and passes through the threaded through hole 93. The threaded shaft 91 is threadedly connected to the threaded through hole 93, and one end of the threaded shaft 91 passing through the threaded through hole 93 is T-shaped.

[0030] In this embodiment, the T-shaped end of the threaded shaft 91 can be rotated quickly. During this process, the threaded shaft 91 is screwed out of the threaded through hole 93 on the frame 92, and the forward and reverse threaded shaft 91 can move downward or upward, thereby driving the connected telescopic plate 8 to move vertically, thereby controlling the amount of mortar stored in the sampler 4.

[0031] Preferably, as another embodiment of the utility model, a motor 11 is provided at the top of the cylinder 1, and the output shaft of the motor 11 is coaxially connected to the upper end of the transmission shaft 2. The motor 11 can drive the transmission shaft 2 and the spiral blade 3 to rotate, thereby realizing automatic extraction of mortar. A fixing frame 12 is provided under the cylinder 1. The fixing frame 12 is concave in shape and both ends are connected to the outside of the cylinder 1. The lower end of the transmission shaft 2 is rotatably connected to the bottom of the fixing frame 12. The fixing frame 12 can be used to connect the transmission shaft 2 so that the transmission shaft 2 rotates smoothly, thereby improving the stability of the equipment.

[0032] Preferably, as another embodiment of the utility model, a horizontal plate 13 is horizontally provided above the cylinder 1, and a plurality of connecting rods 14 are fixedly connected between the cylinder 1 and the horizontal plate 13. The user can hold the horizontal plate 13 and cooperate with the connecting rods 14 to lift the cylinder 1 to insert it into the mortar for extraction.

[0033] Working principle: Hold the horizontal plate 13 and the connecting rod 14, insert the cylinder 1 into the mortar, and start the motor 11 to drive the transmission shaft 2 and the spiral blade 3 to rotate. This process generates an axial propulsion force to transport the mortar into the cylinder 1 and discharge it from the discharge hopper 6 into the sampling box 4. At the same time, according to the needs, the threaded shaft 91 is rotated forward or reversed, so that the threaded shaft 91 moves along the two sides of the threaded through hole 93, that is, screwed in and out, thereby driving the telescopic plate 8 to move along the inside of the sampling box 4, thereby adjusting the capacity of the sampling box 4 to store mortar. When the required amount is extracted and the extraction is completed, press the pressing plates 10 on both sides to drive the discs 75 and round rods 77 on both sides to move toward the middle. During this process, the spring 72 can be squeezed, and the disc 75 will drive the rectangular block 76 to leave the rectangular groove 71 on the sampling box 4. At this time, the fixation of the sampling box 4 has been completed, and it can be pulled outward to allow the rectangular block 76 to go out along the concave groove 74, and then the sampling box 4 can be removed. After removing the sampling box 4, the discharge hopper 5 is unobstructed, and the required mortar can be extracted unlimitedly according to demand.
