Description

Technical Field

[0001] The utility model belongs to the technical field of shaking screen machines, and in particular relates to a mortar shaking screen machine for detecting concrete setting time. Background Art

[0002] A shaking screen machine, also known as a vibrating screen machine, is a device that can screen concrete, such as the existing patent with publication number CN216225261U, which discloses "a shaking screen machine for concrete setting time test, comprising a mounting frame, a vibrating device arranged on the mounting frame and a collecting device arranged below the vibrating device, wherein the vibrating device comprises a feed hopper, a screening net arranged in the feed hopper, a vibrating motor arranged on the feed hopper and an adjusting component for supporting the feed hopper". It can be seen that the application describes a common shaking screen machine, which can realize the screening of concrete for subsequent detection of the setting time of concrete. In order to facilitate the subsequent detection of the setting time of the vibrated concrete, a setting time measuring instrument will be used, such as the existing patent with publication number CN205581109U, which discloses "a handheld cement concrete setting strength and setting time measuring instrument, comprising a measuring instrument body, wherein the measuring instrument body A penetration test structure is provided, in which a pressure sensor is provided, and the penetration test structure includes a penetration needle, the pressure sensor is connected to a signal transmitter, and the signal transmitter is connected to a display terminal pre-written with a time-penetration resistance curve. It can be seen that the application describes a common setting time measuring instrument. When in use, the probe at the lower end of the measuring instrument can be inserted into the concrete sample to be tested, so that the pressure sensor inside the measuring instrument can feel the pressure during insertion. At this time, the pressure sensor sends the pressure it feels to the display terminal through the signal transmitter. The display terminal is pre-set with time-penetration resistance curves of different types of concrete. Therefore, after the signal is sent to the display terminal, it is compared with the time-penetration resistance curve of the concrete type to be tested, and finally it is determined what degree of setting the cement concrete pavement is at that time point, and the setting time detection of the concrete to be tested is completed;

[0003] However, after the shaking screen machine in the above patent is combined with the coagulation time measuring instrument, since there is no structure designed on the shaking screen machine frame to hang and place the coagulation time measuring instrument, the coagulation time measuring instrument cannot be effectively placed and limited, and can only be placed on the shaking screen machine frame with the connecting wires in a messy manner. It has poor stability and is easy to fall during the subsequent operation of the shaking screen machine, causing unnecessary trouble. Therefore, the utility model needs to improve and optimize the existing shaking screen machine. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figures 1 to 3, which is the first embodiment of the utility model, and this embodiment provides a technical solution: a mortar shaking screen machine for detecting concrete setting time, comprising a shaking screen machine frame 1 and a shaking screen machine silo 2 installed above the shaking screen machine frame 1, side bases 4 are welded and fixed to the two side surfaces of the shaking screen machine silo 2, and a vibration spring 5 is installed between the side base 4 and the top surface of the shaking screen machine frame 1, and a vibration motor 3 is installed on the front surface of the shaking screen machine silo 2. When the subsequent vibration motor 3 is running, it can drive the shaking screen machine silo 2 to vibrate continuously to complete the shaking of the concrete in the shaking screen machine silo 2, and a sample box 6 is installed at the inner bottom end of the shaking screen machine frame 1, and the discharge port at the bottom end of the shaking screen machine silo 2 is directly above the sample box 6, and also includes a setting time measuring instrument 7 and a display 10, and the setting time A probe 71 is provided at the bottom end of the time measuring instrument 7, and a display 10 is installed on the left side surface of the shaking screen machine frame 1. It also includes a hanging seat 9. The setting time measuring instrument 7 is fixed on the right side surface of the hanging seat 9, and the hanging seat 9 is slidably arranged on the left inner wall of the shaking screen machine frame 1. The setting time measuring instrument 7 and the display 10 are connected by a signal line. A pressure sensor connected to the probe 71 is also installed inside the setting time measuring instrument 7. A T-shaped slider 91 is welded and fixed on the left side surface of the hanging seat 9, and a T-shaped slide groove 12 corresponding to the T-shaped slider 91 is opened on the left inner wall of the shaking screen machine frame 1. The T-shaped slider 91 slides in the T-shaped slide groove 12, so that the setting time measuring instrument 7 can be stably hung on the inner wall of the shaking screen machine frame 1 through the hanging seat 9, which is convenient for subsequent downward exploration to perform concrete coagulation. In order to detect the time, a limiting structure is also arranged between the T-shaped slider 91 and the shaking screen machine frame 1. The limiting structure includes a pressing groove 81 opened on the inner wall of the left side of the shaking screen machine frame 1, and the pressing groove 81 is above the T-shaped slide groove 12, and a pressing block 82 and a pushing spring 83 are arranged in the pressing groove 81. A side slide groove 84 is opened on the lower wall of the pressing groove 81, and a side slider 85 is arranged in the side slide groove 84, and the top of the side slider 85 is welded and fixed to the pressing block 82, and a side clamping block 86 is welded and fixed to the right side surface of the side slider 85, and a side clamping groove 87 corresponding to the side clamping block 86 is opened on the left side surface of the T-shaped slider 91, and the right end of the side clamping block 86 penetrates into the side clamping groove 87, which can stably limit the T-shaped slider 91, thereby ensuring that the hanger 9 and condensation are stable during daily use. The stability of the time measuring instrument 7 is improved. When the setting time measuring instrument 7 is needed to detect the setting time of the concrete sample in the sample box 6 laterally, one only needs to put one's finger into the pressing groove 81 to press the pressing block 82, so that the pushing spring 83 is compressed, and the side sliding block 85 moves sideways with the pressing block 82, so that the end of the side clamping block 86 moves out of the side clamping groove 87, and the limit of the T-shaped sliding block 91 can be released. At this time, the hanging seat 9 can be slid down, so that the bottom end of the probe 71 is inserted into the inner side of the sample box 6 and contacts the concrete sample inside the sample box 6 to detect the setting time. It is convenient to use. After completing the detection, the hanging seat 9 is slid up again, so that the T-shaped sliding block 91 slides to the top of the T-shaped sliding groove 12, and the end of the side clamping block 86 is clamped into the side clamping groove 87.The bracket 9 and the setting time measuring instrument 7 can be limited again.

[0019] Among them, an ejection hole is opened between the side slide groove 84 and the T-shaped slide groove 12, and the ejection hole corresponds to the side clamping block 86, so that the side clamping block 86 can be ejected smoothly.

[0020] Among them, a cylindrical groove is opened on the left surface of the pressing block 82, the right end of the pushing spring 83 is inserted into the cylindrical groove, and the left end of the pushing spring 83 is fixed on the inner wall of the pressing groove 81, so that the pushing spring 83 is stably installed.

[0021] Among them, strip sliders 61 are welded and fixed on both side surfaces of the sample box 6, and strip slide grooves 11 corresponding to the strip sliders 61 are opened on both side inner walls of the shaking screen machine frame 1. The strip slider 61 slides in the strip slide groove 11, and the front end of the strip slide groove 11 is connected to the front surface of the shaking screen machine frame 1, so that the strip slider 61 can slide out or slide in smoothly.

[0022] Example 2

[0023] See also Figures 1 to 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the rubber seat 13, the positioning protrusion 14 and the positioning slot 62 can be provided to assist in positioning when the sample box 6 is pushed into the inner side of the shaking screen frame 1, so as to facilitate the subsequent material connection.

[0024] Specifically, a rubber seat 13 is embedded in the inner wall of one side of the strip slide 11, and a positioning protrusion 14 is provided on the side of the rubber seat 13. A positioning groove 62 corresponding to the positioning protrusion 14 is opened on the side of the strip slide 61. The end of the positioning protrusion 14 is squeezed into the positioning groove 62, which can play a positioning effect on the strip slide 61. When the strip slide 61 is pushed into the appropriate position in the strip slide 11, the end of the positioning protrusion 14 will be squeezed into the positioning groove 62, thereby playing an auxiliary positioning effect on the strip slide 61 and the sample box 6. At this time, the sample box 6 is directly below the discharge port at the bottom end of the shaking screen silo 2, which is convenient for subsequent material collection.

[0025] The rubber seat 13 and the positioning protrusion 14 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed. A circular cavity is provided in the rubber seat 13, so that the positioning protrusion 14 has sufficient deformation space when squeezed.
