DETAILED DESCRIPTION

[0033] The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The cement mortar vibrating table involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figure 1-9 As shown, in one embodiment, a cement mortar vibrating table is proposed, including a base 1, a housing 101 is installed on the upper end of the base 1, and the upper end of the housing 101 is rotatably connected to the cover 102 through a hinge. A vibration component 2 is provided in the base 1, and a vibrating table 21 is installed at the front end of the vibration component 2. A positioning component 3 is provided in the vibrating table 21, and a test mold 4 is fixed between the positioning component 3 and the vibrating table 21. A feeding component 5 is installed in the housing 101, and the feeding component 5 includes a guide column 501, a connecting plate 503, a sliding frame 504, a fixed seat 505 and a hopper 506. Multiple guide columns 501 and the fixed frame 502 are all installed in the housing 101. The connecting plate 503 is slidably connected to the circumferential surface of the guide column 501, the output end of the cylinder 5021 installed on the upper end of the fixed frame 502 is fixedly connected to the connecting plate 503, the sliding frame 504 is installed at the front end of the connecting plate 503, the fixed seat 505 is slidably connected to the circumferential surface of the sliding frame 504, the silo 506 is installed in the fixed seat 505, and a plurality of discharge ports 507 are provided at the lower end of the silo 506. A plurality of linkage rods 508 are rotatably connected in the silo 506, and a rotating shaft 509 is slidably connected in the linkage rod 508. The circumferential surface of the rotating shaft 509 is installed with an auger blade 5010, and the lower end of the rotating shaft 509 is installed with a bulk material block 5011.

[0035] When the embodiment of the present invention is actually used, the mortar is stored in the silo 506, and the cylinder 5021 is controlled to operate. The cylinder 5021 drives the connecting plate 503, the sliding frame 504 and the fixed seat 505 to descend, so that the discharge port 507 at the lower end of the silo 506 is close to the test mold 4. Then, the fixed seat 505 is controlled to slide back and forth on the sliding frame 504, so that the discharge port 507 at the lower end of the silo 506 moves back and forth in the mold cavity of the test mold 4. At this time, multiple linkage rods 508 are controlled to rotate simultaneously, and the linkage rod 508 drives the rotating shaft 509 to rotate. The rotating shaft 509 drives the auger blade 5010 to rotate. At the same time, the rotating shaft 509 is controlled to descend, driving the position of the bulk material block 5011 to descend, opening the discharge port 507, and then the auger blade 5010 rotates to drive the silo 506 to rotate. The mortar is discharged from the discharge port 507. When the mortar is discharged downward from the discharge port 507, the bulk material block 5011 is conical, so the mortar will spread to the surroundings. At the same time, the hopper 506 and the discharge port 507 move back and forth, so that the mortar can be relatively flat when it falls into the test mold 4, avoiding piles of it falling into the mold cavity of the test mold 4. When the mortar input is completed, the hopper 506 is controlled to rise and reset, and the rotating shaft 509 is controlled to rise and reset at the same time, driving the bulk material block 5011 to block the discharge port 507, avoiding the mortar falling downward due to gravity and causing material waste. Then the vibration component 2 can be controlled to operate to compact the mortar in the test mold 4, and when replenishing the material for the second time in the subsequent time, the hopper 506 is controlled to descend again to open the bulk material block 5011 and then the material replenishing operation can be carried out.

[0036] In one case of an embodiment of the present invention, when the mortar is stored in the silo 506, the auger blade 5010 is controlled to reverse, which can stir the mortar and further mix the mortar evenly. The silo 506 can be directly taken out from the fixed seat 505 to separate it from the equipment. The silo 506 can be cleaned by flushing with clean water later. When different mortars are used, the silo 506 can be cleaned to avoid mixing of different mortars and affecting the detection effect.

[0037] like Figure 4 and 5 As shown, as a preferred embodiment of the present invention, a rotating motor 5012 is mounted on the surface of the sliding frame 504, a driving frame 5013 is mounted on the surface of the fixed seat 505, and a reciprocating screw rod 5014 mounted on the output end of the rotating motor 5012 is threadedly connected to the driving frame 5013.

[0038] When the embodiment of the present invention is actually used, the rotating motor 5012 is controlled to operate, and the rotating motor 5012 drives the reciprocating screw 5014 to rotate. The reciprocating screw 5014 drives the fixed seat 505 to slide back and forth on the circumferential surface of the sliding frame 504 through the driving frame 5013, thereby achieving the effect of controlling the discharge port 507 set at the lower end of the hopper 506 to slide back and forth, so that the mortar can be transported to the test mold 4 more evenly.

[0039] like Figure 6-9 As shown, as another preferred embodiment of the present invention, a drive motor 5015 is installed on the surface of the silo 506, and a drive shaft 5016 is installed at the output end of the drive motor 5015. The drive shaft 5016 and the linkage rod 508 are connected by a first sprocket set 5017, and the linkage rods 508 are connected by a second sprocket set 5018. An electric push rod 5019 is installed in the silo 506, and a traction frame 5020 is installed at the output end of the electric push rod 5019. The rotating shaft 509 is rotatably connected to the traction frame 5020.

[0040] When the embodiment of the present invention is actually applied, the driving motor 5015 is controlled to operate, and the driving motor 5015 will drive the driving shaft 5016 to rotate, and then drive the linkage rod 508 to rotate through the first sprocket group 5017, and at the same time, the multiple linkage rods 508 are rotated simultaneously through the second sprocket group 5018, thereby driving the multiple rotating shafts 509 and the auger blades 5010 to rotate, and at the same time, the electric push rod 5019 is controlled to operate, and the electric push rod 5019 drives the traction frame 5020 to descend, and the traction frame 5020 drives the rotating shaft 509 to descend, thereby driving the bulk material block 5011 to descend, so that the discharge port 507 is opened. At this time, through the rotation of the multiple auger blades 5010, the mortar in the silo 506 can be discharged simultaneously through the multiple discharge ports 507, so that it is transported to the mold cavity in the corresponding position of the test mold 4, thereby achieving the effect of simultaneously inputting mortar into the multiple mold cavities in the test mold 4, thereby improving the mortar feeding efficiency.

[0041] like Figure 10-14 As shown, as another preferred embodiment of the present invention, the positioning assembly 3 includes a sliding shaft 301, a mold sleeve 303, a slot 304 and a limit frame 302. Multiple sliding shafts 301 and limit frames 302 are all slidably connected in the compaction table 21, the mold sleeve 303 is installed on the circumferential surface of the sliding shaft 301, and the slot 304 is opened on the circumferential surface of the sliding shaft 301.

[0042] During actual application of the embodiment of the present invention, after the test mold 4 is placed on the vibration table and its position is corrected, the sliding shaft 301 slides downward in the vibration table, driving the mold sleeve 303 to press against the upper end of the vibration table, and then controlling the movement of the limit frame 302 so that the limit frame 302 is inserted into the slot 304 provided on the circumferential surface of the sliding shaft 301, thereby limiting the position of the sliding shaft 301 and the mold sleeve 303, and thus achieving the effect of fixing the position of the test mold 4.

[0043] like Figure 10-14 As shown, as another preferred embodiment of the present invention, a spring 305 is installed between the vibration table 21 and the limit frame 302, a tension spring 306 is installed between the vibration table 21 and the sliding shaft 301, a rotating frame 307 is installed in the vibration table 21, a rotating shaft 308 is rotatably connected in the rotating frame 307, and a positioning cam 309 is installed on the circumferential surface of the rotating shaft 308.

[0044] When the embodiment of the present invention is actually used, the spring 305 pushes the limit frame 302 so that the limit frame 302 is inserted into the slot 304, thereby achieving the effect of fixing the position of the sliding shaft 301 and the mold sleeve 303. After the mortar in the test mold 4 is vibrated by the vibration component 2, the rotation shaft 308 is controlled to rotate, driving the positioning cam 309 to rotate ninety degrees. Since the protruding end of the positioning cam 309 has a flat surface, when the positioning cam 309 supports the limit frame 302, the limit frame 302 is pulled out of the slot 304. At this time, the tension spring 306 pulls the sliding shaft 301 upward, thereby driving the mold sleeve 303 upward, separating the mold sleeve 303 from the test mold 4, and then the test mold 4 can be taken out from the vibration table 21 for subsequent maintenance.

[0045] like Figure 11 、 14 , 15 and 16, as another preferred embodiment of the present invention, a leak-proof mechanism 6 is installed in the mold sleeve 303, and the leak-proof mechanism 6 includes a connecting rod 601, a blocking plate 602, a limit block 603, a torsion spring 604 and a push rack 606. Multiple groups of connecting rods 601 are rotatably connected in the mold sleeve 303, the blocking plates 602 are installed on the circumferential surface of the connecting rod 601, the limit blocks 603 are installed in the mold sleeve 303, and the two ends of the torsion spring 604 are respectively installed on the connecting rod 601 and the mold sleeve 303, and the circumferential surface of the connecting rod 601 is installed with a push plate 605. The push rack 606 is installed between the sliding racks 504 and is slidably connected to the push plate 605.

[0046] In actual application of the embodiment of the present invention, when the cylinder 5021 drives the connecting plate 503 and the sliding frame 504 to descend, the push frame 606 installed between the sliding frames 504 will push the push plate 605, causing the connecting rod 601 to rotate, thereby driving the blocking plate 602 to rotate and open to both sides, and then the discharge port 507 will enter the mold sleeve 303 and approach the test mold 4 to discharge the mortar. When the mortar is discharged, the sliding frame 504 rises and resets, driving the push frame 606 and the hopper 50 6 rises and resets at the same time, and the discharge port 507 is first moved out of the mold sleeve 303, and then the push frame 606 is separated from the push plate 605. At this time, the blocking plate 602 is driven to rotate and reset through the torsion spring 604, and the surface of the blocking plate 602 fits with the limit block 603 to block the upper end of the mold sleeve 303. When the vibration component 2 is subsequently operated, since the blocking block blocks the upper end of the mold sleeve 303, the mortar in the test mold 4 will not splash outward during vibration, so that the interior of the equipment remains clean and tidy, reducing subsequent cleaning work.

[0047] In one embodiment of the present invention, when the push rack 606 pushes the push plate 605 through the inclined surface set at the lower end of the push rack 606, when the blocking plate 602 is opened, the discharge port 507 and the bulk material block 5011 will enter the mold sleeve 303. At the same time, when the discharge port 507 and the bulk material block 5011 are taken out of the mold sleeve 303, the blocking plate 602 will be closed to avoid the blocking plate 602 causing movement interference when the discharge port 507 and the bulk material block 5011 are raised and reset.

[0048] like Figure 3 and 10 As shown, as another preferred embodiment of the present invention, the vibration component 2 includes a rotating base 201, a support base 202, a rotating column 203 and a connecting column 204. The rotating base 201 and the support base 202 are both installed in the machine base 1. The rotating column 203 is rotatably connected in the rotating base 201. A pair of connecting columns 204 are both installed on the circumferential surface of the rotating column 203. The front end of the connecting column 204 is fixedly connected to the vibration table 21.

[0049] In actual application of the embodiment of the present invention, after the mortar is added to the test mold 4, the vibration table 21 is controlled to rotate and rise with the rotating column 203 as the center, and then quickly falls, and is supported by the support seat 202 at the lowest position of the fall, thereby generating vibration, and thus reciprocating multiple times to achieve the effect of vibrating the mortar in the test mold 4.

[0050] like Figure 3 and 10 As shown, as another preferred embodiment of the present invention, a fixing plate 205 is installed on the circumferential surface of the support seat 202, a vibration motor 206 is installed on the surface of the fixing plate 205, a rotating rod 207 is installed on the output end of the vibration motor 206, and a vibration cam 208 is installed on the circumferential surface of the rotating rod 207.

[0051] When the embodiment of the present invention is actually used, the vibration motor 206 is controlled to operate, and the vibration motor 206 drives the vibration cam 208 to rotate through the rotating rod 207. When the vibration cam 208 rotates, the raised part drives the vibration table to rise, and then makes it fall quickly, thereby achieving the effect of controlling the vibration of the test mold 4 fixed on the vibration table.

[0052] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.

[0053] Secondly: The drawings of the embodiments disclosed in the present invention only involve structures related to the embodiments disclosed in the present invention. Other structures may refer to conventional designs. The same embodiment and different embodiments of the present invention may be combined with each other without conflict.
