Description

Technical Field

[0001] The invention relates to the technical field of concrete preparation, and in particular to a concrete feeding device. Background Art

[0002] During the construction process, in order to detect whether the strength grade of concrete meets the design requirements, it is often necessary to randomly sample the concrete at the pouring site of the construction site and make it into concrete test blocks. By testing the strength of the concrete test blocks, it can be determined whether the strength grade of the concrete during the construction process meets the requirements. During the production process of concrete test pieces, it is usually necessary to go through processes such as vibration, curing, and demolding. Among them, the vibration process of concrete test pieces is a more critical step in the production of concrete test pieces.

[0003] In the prior art, when using a vibrating device for concrete specimens, workers push a wheelbarrow loaded with concrete to one side of the vibrating device, and then usually use a shovel to scoop up the concrete from the wheelbarrow and put it into a specimen mold. Since the specimen mold opening is small and the specimens are usually produced in large batches, manually loading the concrete into the mold is not only time-consuming and labor-intensive, but also there is a situation where a large amount of concrete falls outside the specimen mold during the transfer by the shovel. Summary of the invention

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0030] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0031] Reference Figure 1-Figure 7 As shown, a concrete feeding device comprises a support frame 1, a feeding assembly 2 is arranged on the support frame 1, a fixed feeding port 3 is arranged on the feeding assembly 2, a guide plate 30 is arranged in the fixed feeding port 3, a trolley 7 is arranged on one side of the feeding assembly 2, and further comprises:

[0032] A mounting frame 11 is provided on the top of the support frame 1, a driving shaft 12 is rotatably provided in the mounting frame 11, a rotating motor is provided at one end of the driving shaft 12, a supporting plate 20 connected to the driving shaft 12 is provided at the bottom of the feeding assembly 2, and a pit is also provided at the bottom of the feeding assembly 2;

[0033] When the trolley 7 moves to the front end of the pit, the rotating motor drives the driving shaft 12 to rotate, so that the loading assembly 2 deflects toward the inside of the pit, thereby lowering the loading port to facilitate loading.

[0034] The movable feeding port 4 is rotatably connected to the fixed feeding port 3 via a fixed rotating shaft 42. A bracket 31 for lifting the movable feeding port 4 is provided at one end of the fixed feeding port 3. A vibration motor 41 is provided on the movable feeding port 4.

[0035] When the loading assembly 2 rotates downward, one end of the movable loading port 4 will contact the front end of the pit, and then the trolley 7 can be turned over to pour concrete into the movable loading port 4.

[0036] A limiting component 6 is arranged between the fixed feeding port 3 and the movable feeding port 4, and is used to limit the movable feeding port 4;

[0037] The limit assembly 6 can be opened and is initially in a closed state, mainly to maintain the stability of the movable loading port 4. When the loading assembly 2 rotates downward and the movable loading port 4 contacts the ground, the limit assembly 6 will open, and the loading assembly 2 continues to deflect downward. The movable loading port 4 will also rotate upward under the obstruction of the ground, which is used to adjust the position of the movable loading port 4 to facilitate loading.

[0038] The trigger component 5 is arranged on the movable feeding port 4 and is used to control the opening and closing of the limit component 6. When the movable feeding port 4 contacts the ground, it will first touch the trigger component 5, and the limit component 6 will be started to open through the trigger component 5. When the dumping is completed, when the feeding component 2 rotates back, the movable feeding port 4 is filled with concrete, and under the action of its gravity, the movable feeding port 4 will be pressed down, keeping the trigger component 5 still in the squeezed state. Only when the bracket 31 in the fixed feeding port 3 contacts the movable feeding port 4 and drives the movable feeding port 4 to deflect upward through the bracket 31, the trigger component 5 is disconnected, and at this time, the movable feeding port 4 can be fixed by the limit component 6.

[0039] In one embodiment, the trigger assembly 5 includes a convex plate 51 fixed to one side of the movable feeding port 4, a trigger movable plate 53 is provided at the bottom of the convex plate 51, a trigger button 52 is provided between the trigger movable plate 53 and the convex plate 51, the trigger button 52 is electrically connected to the limit assembly 6, and telescopic assemblies 54 are also provided at both ends of the convex plate 51, and the trigger movable plate 53 is movably connected to the convex plate 51 through the telescopic assemblies 54;

[0040] When the loading assembly 2 rotates into the pit, the trigger assembly 5 at the front end of the movable loading port 4 will touch the ground. At this time, the trigger movable plate 53 is squeezed, causing the telescopic assembly 54 to shrink inward. When the trigger movable plate 53 touches the trigger button 52, the limit assembly 6 will be activated to open, so that the movable loading port 4 can be deflected and the position can be adjusted.

[0041] In one embodiment, the telescopic assembly 54 includes a fixed sleeve 541 fixed on the convex plate 51, a telescopic rod 542 connected to the trigger movable plate 53 is movably arranged in the fixed sleeve 541, a pressure plate 543 is arranged in the fixed sleeve 541 and on the side wall of the telescopic rod 542, and a return spring 544 is arranged between the pressure plate 543 and the inner wall of the fixed sleeve 541 and is sleeved on the telescopic rod 542;

[0042] When the trigger movable plate 53 is squeezed, the trigger movable plate 53 pushes the pressure plate 543 through the telescopic rod 542, and the pressure plate 543 squeezes the return spring 544 until the trigger movable plate 53 contacts the trigger button 52. When the movable feeding port 4 rotates upward, the trigger movable plate 53 will also move away from the trigger button 52 and return to its original position under the action of the elastic force of the return spring 544, which will close the limit assembly 6 and fix the movable feeding port 4 again.

[0043] In one embodiment, the limiting assembly 6 includes a protective shell 61, which is connected to the guide plate 30 through a fixed plate 60, and limiting plates 68 fixed to the movable feeding port 4 are arranged on both sides of the protective shell 61. A positioning assembly is arranged in the protective shell 61, and the movable end of the positioning assembly is movably connected to the limiting plate 68;

[0044] The trigger button 52 is electrically connected to the positioning assembly. When the trigger button 52 is pressed, the positioning assembly will retract the movable end, thereby disengaging from the limit plate 68. At this time, the restraint of the movable loading port 4 is released, and it can rotate relative to the fixed loading port 3.

[0045] In one embodiment, the positioning assembly includes a driving gear 63 rotatably disposed in a protective housing 61, a driving motor is disposed at the bottom of the driving gear 63, and two sides of the driving gear 63 are meshed with tooth plates 64 slidably connected to the protective housing 61, and an insert plate 66 inserted into a limit plate 68 is disposed at one end of the tooth plate 64 away from the driving gear 63;

[0046] When the trigger button 52 is pressed, the drive motor is started, and the drive motor drives the drive gear 63 to rotate, thereby driving the toothed plates 64 on both sides to move, so that the plug plate 66 is separated from the limit plate 68.

[0047] In one embodiment, baffles 62 are provided on both sides of the protective housing 61, and the baffles 62 are located between the insert plate 66 and the tooth plate 64. A movable rod 65 penetrating the baffle 62 is also provided between the insert plate 66 and the tooth plate 64, and a limit spring 67 is sleeved on the movable rod 65.

[0048] When the plug plate 66 is separated from the limit plate 68, the plug plate 66 will squeeze the limit spring 67. After the trigger button 52 is released, the drive motor is directly turned off, and the plug plate 66 will be inserted into the limit plate 68 under the elastic force of the limit spring 67 to complete the limitation.

[0049] In one embodiment, the loading assembly 2 includes a conveying shell 21, a discharge port 211 is provided at the bottom of one end of the conveying shell 21 away from the fixed loading port 3, a threaded conveying rod 22 is rotatably provided in the conveying shell 21, a fixed frame 23 is provided at one end of the conveying shell 21, a conveying motor 24 is installed in the fixed frame 23, an active roller 25 is connected to the output end of the conveying motor 24, a driven roller 26 is provided at one end of the threaded conveying rod 22, and the active roller 25 and the driven roller 26 are connected to each other through a conveyor belt 27.
