DETAILED DESCRIPTION
[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0025] like Figures 1-3 As shown, this application discloses a Los Angeles abrasion test material pretreatment device, which includes an outer frame 1, a treatment box 2 installed on the outer frame 1, the upper end of the treatment box 2 is an open structure, and a partition plate 3 is fixed in the middle of the treatment box 2 along its width direction. The partition plate 3 can divide the internal space of the treatment box 2 into two independent spaces: a washing chamber 4 and a screening chamber 5.
[0026] A support sleeve 6 is welded to the outside of the processing box 2 at a position corresponding to one end of the partition plate 3. A screening unit 8 is installed on the support sleeve 6 through a bidirectional adjustment component 7. The material to be tested is placed in the end of the screening unit 8 facing the processing box 2. The screening unit 8 can swing freely in the vertical and / or horizontal directions through the bidirectional adjustment component 7.
[0027] In the above embodiments, the outer frame 1 of this application can raise the processing box 2 to a certain height, which facilitates the operation of the screening unit 8 by the test personnel. The height of the partition plate 3 inside the processing box 2 can be set lower than the upper port of the processing box 2, so that the test personnel can shorten the moving distance of the screening unit 8 when moving it from one side of the partition plate 3 to the other side. The bidirectional adjustment component 7 provided on the support sleeve 6 on the outside of the processing box 2 not only provides support for the screening unit 8 through the support sleeve 6, but also allows the test personnel to easily adjust the position of the screening unit 8 as needed.
[0028] This application allows the temporary storage unit 8 containing the test aggregate to be mounted on the support sleeve 6 via a bidirectional adjusting component 7. When the end of the sieve unit 8 containing the test aggregate is located in the cleaning chamber 4 or the sieve chamber 5, the test personnel can quickly shake it vertically or horizontally (or simultaneously in both directions). This efficiently sieves small particles that do not meet the requirements from the sieve unit 8 into the sieve chamber 5, or dissolves the contaminants in the sieved aggregate into the water in the cleaning chamber 4, thus completing the pretreatment of the test aggregate. Since the cleaning chamber 4 and the sieve chamber 5 of this application are integrated into the same processing box 2, compared with the prior art, it can effectively save the trouble of the test personnel to transport the sieved test aggregate to other cleaning areas. Moreover, the sieve unit 8 of this application does not need to pour out the test aggregate after sieving; it can be directly cleaned in the cleaning chamber 4. This further simplifies the processing flow of the test material and improves the efficiency of the test.
[0029] Further, as shown in Figure 2 The screening unit 8 includes a drive swing arm 81, one end of the drive swing arm 81 extends into the treatment box 2, the other end of the drive swing arm 81 is located outside the treatment box 2, and the end of the drive swing arm 81 located in the treatment box 2 is fixedly connected with a perforated cylinder 82, and the lower end of the perforated cylinder 82 is detachably installed with a metal sieve 83 through bolts and nuts.
[0030] In the above embodiment, the drive swing arm 81 of the present application is installed on the bidirectional adjusting part 7, and the position of the part of the drive swing arm 81 located inside the treatment box 2 can be adjusted by the tester through the part of the drive swing arm 81 located outside the treatment box 2. The perforated cylinder 82 fixedly connected with the end of the drive swing arm 81 located in the treatment box 2 can form a container with the metal sieve 83 at the bottom of the perforated cylinder 82 for containing the aggregate to be tested. During screening, the tester can shake the perforated cylinder 82 through the drive swing arm 81, and the metal sieve 83 at the bottom of the perforated cylinder 82 can realize the screening effect of the aggregate. The metal sieve 83 and the perforated cylinder 82 of the present application are installed together through bolts and nuts, which is convenient for the tester to freely replace metal sieves 83 of different specifications at the bottom of the perforated cylinder 82 according to needs. Since the perforated cylinder 82 and the metal sieve 83 of the present application both have a large number of holes, when the tester moves the perforated cylinder 82 to the washing chamber 4 containing water through the drive swing arm 81 and shakes the perforated cylinder 82, the dust and dirt in the screened aggregate can quickly contact and dissolve with the water in the washing chamber 4 through the holes in the perforated cylinder 82 and the metal sieve 83, thereby realizing efficient cleaning of the aggregate to be tested.
[0031] Further, as shown in Figure 1 , Figure 3 and Figure 4 The top of the perforated cylinder 82 is detachably installed with a loss-preventing cover plate 9 through bolts and nuts.
[0032] In the above embodiment, the top of the perforated cylinder 82 is detachably installed with a loss-preventing cover plate 9 through bolts and nuts. Whether the perforated cylinder 82 is in the process of screening or cleaning and shaking, the loss-preventing cover plate 9 can effectively prevent the aggregate from being scattered, so as to avoid affecting the accuracy of the test.
[0033] Further, as shown in Figure 1 and Figure 2 The bidirectional adjusting part 7 includes a rotating shaft 71, the rotating shaft 71 is inserted into the support sleeve 6 and rotationally connected therebetween, the upper end of the rotating shaft 71 is fixedly installed with a slot-shaped bracket 72, the middle of the slot-shaped bracket 72 is hingedly connected with a mounting block 73, and the mounting block 73 is fixedly sleeved on the drive swing arm 81.
[0034] In the above embodiment, the lower end of the groove bracket 72 of the present application is rotatably connected to the support sleeve 6 through the rotating shaft 71, and the notch on the groove bracket 72 is hingedly connected to the mounting block 73 installed on the driving swing arm 81. The driving swing arm 81 can swing up and down on the hinge shaft between the groove bracket 72 and the mounting block 73, and at the same time, the driving swing arm 81 can also rotate horizontally around the axis of the rotating shaft 71. Therefore, when the porous cylinder 82 needs to be shaken during the screening or cleaning process of the aggregate to be tested, the test personnel can shake the driving swing arm 81 in the upward or horizontal direction, so as to achieve the shaking effect of the porous cylinder 82. Or when the porous cylinder 82 is moved between the cleaning chamber 4 and the screening chamber 5, the test personnel can swing the driving swing arm 81 according to the needs, so that the porous cylinder 82 can be smoothly moved. Therefore, the present application has good controllability and flexibility during use.
[0035] Further, as shown in Figure 2 and Figure 4 , the part of the driving swing arm 81 between the mounting block 73 and the porous cylinder 82 is inclined downward, and the length of the inclined part of the driving swing arm 81 plus the diameter of the circular cross section of the porous cylinder 82 is less than the length of the other part of the driving swing arm 81.
[0036] In the above embodiment, the part of the driving swing arm 81 between the mounting block 73 and the porous cylinder 82 is inclined downward, so that the test personnel does not need to press very low to smoothly send the porous cylinder 82 to the cleaning chamber 4 or the screening chamber 5, which improves the comfort of the test personnel during operation. The length of the inclined part of the driving swing arm 81 plus the diameter of the circular cross section of the porous cylinder 82 is less than the length of the part of the driving swing arm 81 away from the porous cylinder 82 on the side of the mounting block 73. According to the principle of lever, the test personnel will be more labor-saving when moving the porous cylinder 82 at the end of the driving swing arm 81 through the driving swing arm 81.
[0037] Further, as shown in Figure 1 and Figure 2 , a holding handle 10 is welded to the side of the driving swing arm 81 away from the porous cylinder 82, and the axis of the holding handle 10 is perpendicular to the axis of the driving swing arm 81 at the installation position.
[0038] In the above embodiment, the holding handle 10 provided on the driving swing arm 81 in the above manner facilitates the test personnel to have a comfortable power point for the hand to control the movement of the driving swing arm 81.
[0039] Further, as shown in Figure 1 and Figure 2 , an upwardly curved auxiliary handle 11 is welded to the end of the holding handle 10 away from the porous cylinder 82.
[0040] In the above embodiment, when the test personnel need to lift the porous cylinder 82 upward, the test personnel can also control the movement of the driving swing arm 81 through the auxiliary handle 11, which can make the position of the hands of the test personnel not too low compared to controlling the movement of the driving swing arm 81 by holding the handle 10, thereby effectively improving the flexibility of the use of the present application.
[0041] Further, as shown in Figure 4 The lower end of the support sleeve 6 is fixedly connected with a hanging ring 12, and a traction rope 13 is tied on the hanging ring 12.
[0042] In the above embodiment, when the test personnel need to add the to-be-tested aggregate into the porous cylinder 82 or take out the pre-processed to-be-tested aggregate, the end of the traction rope 13 away from the hanging ring 12 can be tied on or hung on the auxiliary handle 11, so that the position of the porous cylinder 82 is temporarily fixed through the driving swing arm 81, thereby facilitating the test personnel to add or take out the aggregate.
[0043] Further, as shown in Figures 2-4 The outer side of the bottom of the cleaning chamber 4 is provided with a valve-equipped drain 14, and the outer side of the bottom of the screening chamber 5 is provided with an up-and-down through-going residue discharge port 15.
[0044] In the above embodiment, the valve-equipped drain 14 at the bottom of the cleaning chamber 4 of the present application facilitates the test personnel to clean and discharge the sewage inside; and the residue discharge port 15 at the bottom of the screening chamber 5 can guide the broken aggregate screened from the metal screen 83 at the bottom of the porous cylinder 82 to be discharged into the collection container below during use.
[0045] The implementation principle of the present embodiment is as follows: before the test personnel need to perform the abrasion test on the to-be-tested aggregate taken out in advance, the test personnel first confirms the specification of the metal screen 83 at the bottom of the porous cylinder 82, and if the specification of the metal screen 83 does not meet the requirements, a new metal screen 83 needs to be replaced at the bottom of the porous cylinder 82. Next, clean water is injected into the cleaning chamber 4, the anti-loss cover plate 9 at the top of the porous cylinder 82 is opened, and the to-be-tested aggregate is loaded into the porous cylinder 82, and then the anti-loss cover plate 9 at the top of the porous cylinder 82 is reinstalled. Next, the test personnel can control the driving swing arm 81 through the handle 10 to place the porous cylinder 82 into the screening chamber 5, and the driving swing arm 81 is used to shake the porous cylinder 82 to start the screening work. After the screening work is completed, the test personnel controls the driving swing arm 81 to directly transfer the porous cylinder 82 into the clean water in the cleaning chamber 4, and continues to shake the porous cylinder 82 to realize the cleaning work of the aggregate in the porous cylinder 82. After the cleaning work is completed, the aggregate in the porous cylinder 82 is taken out and placed into an oven for drying. After the drying is completed, the to-be-tested aggregate with a proper weight is placed into an abrasion machine to start the abrasion test.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
