Description

Technical Field

[0001] This utility model belongs to the field of aggregate washing and screening technology, specifically, it relates to a test device for washing and screening aggregate raw materials for highway testing. Background Technology

[0002] The process of separating a mixture of materials of different particle sizes into various particle size grades using a perforated sieve is called screening. Water washing screening is a process of screening by forming a suspension in water. It is used to test raw materials in highway engineering and to observe whether the materials are qualified.

[0003] Select a set of test sieves with a bottom diameter of 0.075mm and a bottom diameter of 4.75mm and 0.075mm, or 2.36mm and 0.075mm, based on the aggregate particle size. Both sides of the sieves should be moistened with water before the test.

[0004] Currently, the testers are directly placing the sieve in the water tank, turning on the tap, and rotating the sieve while rinsing it. However, this method cannot guarantee that the water source will evenly rinse the sieve, and the testers cannot guarantee stability when rotating the sieve directly in the water tank.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A test device for washing and screening aggregate raw materials for highway testing includes a base plate with a support shaft installed at its bottom center. The lower end of the support shaft is mounted on the upper part of a bracket via a bearing. Two parallel sleeves are installed at the bottom of the bracket, and clamping and locking units are installed at both ends of the sleeves to lock the bracket in a water tank. A fixed clamping plate is vertically installed on one side of the upper part of the base plate, and a movable clamping plate is slidably installed on the other side. The middle of the outer wall of the movable clamping plate is rotatably connected to the end of an adjusting bolt via a bearing. The adjusting bolt is threaded and tightened. The bottom plate is fixed to a column at one end and has a stacked sieve located between the movable and fixed clamping plates. A spraying mechanism is installed in the water tank to spray and wash the aggregates on the sieve. The bottom plate is placed in the water tank through two sleeves at the bottom of the bracket, along with adjusting rods and clamping plates. The two adjusting rods are then rotated through their screws to move the clamping plates within the sleeves until they expand and clamp within the water tank. The rotating mechanism allows the test personnel to rotate and spray simultaneously for quick connection.

[0008] In a preferred embodiment of the present invention, the clamping and locking unit includes an adjusting rod, a lead screw is fixed to one end of the adjusting rod near the sleeve, the lead screw is threaded into the end of the sleeve, and a clamping plate is installed at the other end of the adjusting rod, and the clamping plate is a rubber clamping plate.

[0009] In a preferred embodiment of the present invention, the spraying mechanism includes a spray pipe and a support arm. One end of the support arm is fixed to the side wall of the bracket, and the other end of the support arm is fixed to the water pipe. The inlet of the water pipe is connected to the outlet of the hose, and the inlet of the hose is connected to a faucet installed on the water tank.

[0010] In a preferred embodiment of this utility model, the inlet of the spray pipe is connected to the outlet of the water pipe, and the length of the spray pipe is half the diameter of the screen.

[0011] In a preferred embodiment of this utility model, the bottom of the base plate is equipped with rollers and rests on the bracket.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model places the base plate in the water tank through two sleeves at the bottom of the bracket, as well as adjusting rods and clamping plates. Then, by rotating the two adjusting rods, the clamping plates are moved within the sleeves through their lead screws until the clamping plates expand and clamp within the water tank. Furthermore, the rotating mechanism allows test personnel to rotate and spray simultaneously, facilitating quick connection.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] like Figures 1 to 3 As shown, a test device for washing and screening aggregate raw materials for highway testing includes a plate 15, with a support shaft 14 installed at the center of its bottom. The lower end of the support shaft 14 is mounted on the upper part of a bracket 12 via a bearing. Two parallel sleeves 13 are installed at the bottom of the bracket 12, and clamping and locking units are installed at both ends of the two sleeves 13 to lock the bracket 12 in the water tank 1. A fixed clamping plate 17 is vertically installed on one side of the upper part of the base plate 15, and a movable clamping plate 3 is slidably arranged on the other side. The middle of the outer wall of the movable clamping plate 3 is rotatably connected to the end of an adjusting bolt 2 via a bearing. The adjusting bolt 2 is threaded and passes through a column fixed at one end of the base plate 15. A stacked sieve 4 is arranged on the base plate 15 between the movable clamping plate 3 and the fixed clamping plate 17. A spraying mechanism is arranged in the water tank 1 to spray and wash the aggregates on the sieve 4.

[0022] like Figures 1 to 3 As shown, in a specific embodiment, the clamping and locking unit includes an adjusting rod 10. One end of the adjusting rod 10 near the sleeve 13 is fixed with a lead screw 11, which is threaded into the end of the sleeve 13. The other end of the adjusting rod 10 is fitted with a clamping plate 16, which is a rubber clamping plate. The spraying mechanism includes a spray pipe 5 and a support arm 9. One end of the support arm 9 is fixed to the side wall of the bracket 12, and the other end of the support arm 9 is fixed to the water pipe 6. The inlet of the water pipe 6 is connected to the outlet of the hose 7. The inlet of the hose 7 is connected to the faucet 8 installed on the water tank 1. The inlet of the spray pipe 5 is connected to the outlet of the water pipe 6. The length of the spray pipe 5 is half the diameter of the sieve 4. The bottom of the base plate 15 is fitted with rollers and overlaps the bracket 12.

[0023] The implementation principle of the highway test aggregate raw material washing and screening test device in this embodiment is as follows: The bottom plate 15 is placed in the water tank 1 through the two sleeves 13 at the bottom of the bracket 12, as well as the adjusting rod 10 and the clamping plate 16. Then, the two adjusting rods 10 are rotated in the sleeves 13 through their screws 11 to move the clamping plate 16 until the clamping plate 16 forms an expanded clamping purpose in the water tank 1.

[0024] The aggregate is placed in the first layer of the double-layered sieve 4, and then the sieve 4 is placed on the base plate 15. The adjusting bolt 2 is rotated to move the moving clamp 3 and cooperate with the fixed clamp 17 to clamp and fix the sieve 4. Then, the water tap 8 is turned on, and the aggregate on the sieve 4 is evenly sprayed and washed through several spray holes at the bottom of the spray pipe 5. The test personnel can rotate the sieve 4 by rotating the base plate 15, which is convenient and quick.
