Description

Technical Field

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

[0002] The production of concrete specimens is an indispensable part in civil engineering construction projects and scientific research in designing structural engineering. In the process of making concrete specimens, pouring and loading is a key step;

[0003] In the pouring process of concrete specimens in the prior art, concrete is usually directly scooped up from a storage device with a shovel or spade and then poured into a mold for loading. Often, before the concrete is transferred from the storage device to the mold, there are already significant problems of concrete stratification or solidification, which cannot truly reflect the actual engineering properties of the concrete. In addition, during the pouring and loading process of the existing concrete, due to the lack of a filtration process, there may be debris in the concrete, which affects the preparation of the specimens.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0005] The object of the present invention is to provide a concrete specimen casting and feeding device to solve the problem that the concrete specimens in the prior art mentioned in the above background technology are stratified or solidified in the feeding device, which cannot truly reflect the real engineering properties of the concrete, and the concrete lacks a filtering process during the feeding process, resulting in the debris in the concrete entering the mold together with the concrete, affecting the production of the specimen.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A concrete specimen pouring and feeding device comprises a base and also comprises:

[0008] The pouring unit comprises a feeding assembly disposed at the upper end of the base for caching concrete raw materials, a pouring assembly disposed at the discharge end of the feeding assembly for pouring the specimen mold, and a driving assembly disposed at one side of the pouring assembly for synchronously driving the feeding assembly to stir the supplied concrete and driving the pouring assembly to pour and load the materials;

[0009] The filtering unit comprises a filtering component which is arranged on the upper part of the material supply component and is used for filtering the concrete before entering the material supply component.

[0010] Furthermore, the feeding assembly comprises:

[0011] A guide hopper, fixedly connected to the upper end of the base;

[0012] A mixing sleeve, one end of which is connected to the discharge end of the guide hopper at the bottom, and the other end of which is connected to the feed end of the casting assembly. The guide hopper and the bottom surface of the mixing sleeve are both inclined, and are used to guide the concrete in the guide hopper into the casting assembly.

[0013] A stirring paddle is arranged inside the stirring sleeve and connected to the driving assembly, and is used for preliminarily stirring the concrete in the inner area of ​​the stirring sleeve before entering the casting assembly.

[0014] Furthermore, the casting assembly comprises:

[0015] A feeding pipe is connected to the upper end of the base through a bracket, and a feeding channel of the feeding pipe extends from bottom to top;

[0016] A screw pusher is rotatably arranged inside the feeding pipe, and is used to push the concrete after preliminary stirring by the stirring paddle from bottom to top along the feeding pipe;

[0017] The pouring pipe is arranged at one side of the upper end of the pouring pipe and is used to introduce the concrete pushed by the screw push paddle into the mold of the test piece.

[0018] Furthermore, the casting pipe is designed to be a wave-shaped pipe with a smooth inner wall that gradually extends obliquely downward, so as to reduce the initial speed of the concrete when the casting pipe falls into the specimen mold.

[0019] Furthermore, the driving assembly includes:

[0020] A driving motor is installed on one side of the guide hopper located at the casting assembly;

[0021] A driving shaft connected to the driving end of the driving motor, the driving shaft extending from the upper side of the stirring sleeve to the lower side of the stirring sleeve, and the stirring paddle fixing sleeve being arranged on the outer side of the driving shaft;

[0022] The chain transmission mechanism has one end connected to the lower end of the driving shaft and the other end connected to the lower end of the screw propeller, and is used to drive the screw propeller and the stirring paddle to rotate synchronously.

[0023] Furthermore, the filtering component comprises:

[0024] A fixed block, provided with two groups, fixedly connected to the upper end of the feeding assembly;

[0025] The rotating shaft is rotated and inserted into the two sets of fixed blocks in sequence;

[0026] Rotating blocks are provided in two groups, and fixed sleeves are arranged on the outside of the rotating shaft;

[0027] The filter screen is arranged outside the rotating block and located at the upper opening of the feeding assembly, and is used for filtering the concrete before entering the feeding assembly.

[0028] Furthermore, a sinking rod is fixedly connected to one side of the rotating block;

[0029] The upper end of the filter screen is fixedly connected to the lower end of the sinking rod near the edge, and is used to extend the upper end of the filter screen downward to a plane lower than the upper end opening of the feeding assembly.

[0030] Furthermore, the filtering unit also includes a collecting frame located on one side of the feeding assembly and used to collect debris dumped from the filtering assembly.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention drives the rotating block to rotate through the rotating shaft, and the rotating block drives the filter screen to flip from the upper end of the limit frame to the upper end of the collection frame through the sinking rod, so that the originally filtered debris is poured into the collection frame. For the debris mixed in the filter holes of the filter screen, the adjusting rod can be quickly rotated back and forth, so that the debris mixed in the filter screen is thrown into the collection frame under the action of inertia, and then the filter screen is rotated in the opposite direction to the upper end of the limit frame. The reverse dumping method of the debris is not only convenient and fast, but also the rotation method of the present invention can prevent the debris from being stuck in the pores of the filter screen, which is convenient for cleaning the filter screen.

[0033] 2. The present invention drives the stirring paddle to rotate through the driving shaft, so that the concrete in a larger area inside the stirring sleeve is initially stirred, preventing the concrete from being stratified or solidified inside the stirring sleeve before entering the feeding pipe, and ensuring that the concrete poured in the specimen mold can reflect the real engineering characteristics.

[0034] 3. The present invention drives the driven gear to rotate through a chain, and the driven gear drives the concrete at the inlet to enter the outlet along the feeding pipe in a rotating and pushing manner through a spiral push paddle, thereby further stirring the concrete in the transfer process before pouring, further avoiding uneven distribution of concrete during pouring, and ensuring that the concrete characteristics reflected by the test piece are more accurate.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-5 , the present invention provides a technical solution:

[0043] A concrete specimen pouring and feeding device comprises a base 100 and further comprises:

[0044] The pouring unit 1 comprises a feeding assembly 11 disposed at the upper end of the base 100 for caching concrete raw materials, a pouring assembly 12 disposed at the discharge end of the feeding assembly 11 for pouring the specimen mold, and a driving assembly 13 disposed at one side of the pouring assembly 12 for synchronously driving the feeding assembly 11 to stir the supplied concrete and driving the pouring assembly 12 to pour and load the materials;

[0045] The filtering unit 2 includes a filtering component 21 disposed on the upper portion of the feeding component 11 and used for filtering the concrete before entering the feeding component 11 .

[0046] It should be noted that: when concrete needs to be poured in the specimen mold, the specimen mold is aligned with the discharge end of the pouring component 12, and then the concrete is poured into the feeding component 11. The concrete entering the feeding component 11 is filtered by the filtering component 21, so that the debris in the concrete is screened out. Subsequently, the driving component 13 is started, and the driving component 13 drives the pouring component 12 to stir and push the concrete in the feeding component 11 into the specimen mold, so as to avoid the concrete from being separated or solidified before entering the specimen mold.

[0047] As an improvement, Figure 1-3 As shown, the feeding assembly 11 includes:

[0048] A guide hopper 111 is fixedly connected to the upper end of the base 100;

[0049] A stirring sleeve 112, one end of which is connected to the discharge end of the guide hopper 111, and the other end of which is connected to the feed end of the casting assembly 12. The bottom surfaces of the guide hopper 111 and the stirring sleeve 112 are both inclined, and are used to guide the concrete in the guide hopper 111 into the casting assembly 12;

[0050] The stirring paddle 113 is disposed inside the stirring sleeve 112 and connected to the driving assembly 13 , and is used for preliminarily stirring the concrete in the inner area of ​​the stirring sleeve 112 before entering the casting assembly 12 .

[0051] Further, such as Figure 2-3 As shown, the casting assembly 12 includes:

[0052] A feeding pipe 121 is connected to the upper end of the base 100 through a bracket 1213, and a feeding channel of the feeding pipe 121 extends from bottom to top;

[0053] The screw push paddle 122 is rotatably disposed inside the feeding pipe 121, and is used to push the concrete preliminarily stirred by the stirring paddle 113 from bottom to top along the feeding pipe 121;

[0054] A pouring pipe 123, provided at one side of the upper end of the pouring pipe 123, for introducing the concrete pushed by the screw pusher 122 into the mold of the specimen;

[0055] A material inlet 1211 connected to the stirring sleeve 112 is provided at a lower side of the feeding pipe 121 , and a material outlet 1212 connected to the pouring pipe 123 is provided at an upper side of the feeding pipe 121 .

[0056] Furthermore, Figure 2 As shown, the pouring pipe 123 is configured as a wave-shaped structure with a smooth inner wall and gradually extending obliquely downward, so as to reduce the initial velocity of the concrete when the pouring pipe 123 falls into the specimen mold;

[0057] By setting the pouring tube 123 to have a smooth inner wall and a wave-like shape that gradually extends obliquely downward, the concrete will not slide into the specimen mold too quickly along the pouring tube 123, effectively preventing the concrete from entering the specimen mold and splashing out of the mold.

[0058] Among them, Figure 3 As shown, the driving assembly 13 includes:

[0059] A driving motor 131 is installed on one side of the guide hopper 111 located at the casting assembly 12;

[0060] A driving shaft 132 connected to the driving end of the driving motor 131, the driving shaft 132 extends from the upper side of the stirring sleeve 112 to the lower side of the stirring sleeve 112, and the stirring paddle 113 is fixedly sleeved on the outer side of the driving shaft 132;

[0061] A chain transmission mechanism 133, one end of which is connected to the lower end of the driving shaft 132, and the other end of which is connected to the lower end of the propeller 122, for driving the propeller 122 and the stirring paddle 113 to rotate synchronously;

[0062] The chain transmission mechanism 133 includes: a driving gear 1331 fixedly connected to the lower end of the driving shaft 132, a driven gear 1333 fixedly connected to the lower end of the screw propeller 122 and located outside the feeding pipe 121, and a chain 1332 meshing between the driven gear 1333 and the outer side of the driving gear 1331;

[0063] The diameter of the driving gear 1331 is greater than the diameter of the driven gear 1333 , ensuring that the rotation speed of the propeller 122 is greater than the rotation speed of the stirring paddle 113 .

[0064] As an improvement, Figure 1 , Figure 4-5 As shown, the filter assembly 21 includes:

[0065] The fixed block 211 is provided with two groups and is fixedly connected to the upper end of the feeding assembly 11;

[0066] The rotating shaft 212 is rotated and inserted into the two sets of fixing blocks 211 in sequence;

[0067] The rotating block 213 is provided with two groups and is fixedly sleeved on the outer side of the rotating shaft 212;

[0068] The filter screen 215 is arranged outside the rotating block 213 and located at the upper opening of the feeding assembly 11, and is used to filter the concrete before entering the feeding assembly 11;

[0069] One end of the rotating shaft 212 is fixedly connected to an adjusting rod 2121 for adjusting the rotation of the rotating shaft 212;

[0070] A limit frame 216 for limiting the filter 215 is fixedly inserted inside the guide hopper 111 and below the filter 215 . The horizontal plane where the upper end of the limit frame 216 is located is lower than the horizontal plane where the upper end opening of the guide hopper 111 is located.

[0071] Further, such as Figure 4 As shown, a sinking rod 214 is fixedly connected to one side of the rotating block 213;

[0072] The upper end of the filter screen 215 is fixedly connected to the lower end of the sinking rod 214 near the edge, so as to extend the upper end of the filter screen 215 downward to a plane lower than the upper end opening of the feeding assembly 11 .

[0073] By fixing one side of the rotating block 213 to the sinking rod 214, the plane where the upper end of the filter screen 215 is located is lower than the plane where the upper end opening of the guide hopper 111 is located, ensuring that when concrete is poured into the guide hopper 111, the concrete above the filter screen 215 will not overflow from the upper end of the guide hopper 111 due to the faster pouring speed of the concrete and the faster filtering speed of the filter screen 215.

[0074] Furthermore, the filtering unit 2 also includes a collecting frame 22 located on one side of the feeding assembly 11 for collecting debris dumped from the filtering assembly 21 .

[0075] It should be noted that: Figure 1-3 As shown, in the specific implementation process of the present invention, the specimen mold is placed at the lower end opening of the casting pipe 123, and then concrete is poured into the guide hopper 111. Before the concrete enters the guide hopper 111, it is filtered through the filter screen 215, thereby effectively preventing debris from entering the guide hopper 111 along with the concrete.

[0076] like Figure 4-5As shown, the filtered debris remains on the filter screen 215. After each concrete pouring work is completed, the adjusting rod 2121 is rotated, and the adjusting rod 2121 drives the rotating block 213 to rotate through the rotating shaft 212. The rotating block 213 drives the filter screen 215 to flip from the upper end of the limit frame 216 to the upper end of the collecting frame 22 through the sinking rod 214, so that the originally filtered debris is poured into the collecting frame 22. For the debris mixed in the filter holes of the filter screen 215, the adjusting rod 2121 can be quickly rotated back and forth, so that the debris mixed in the filter screen 215 is thrown into the collecting frame 22 under the action of inertia, and then the filter screen 215 is reversely rotated to the upper end of the limit frame 216. The reverse dumping method is not only convenient and fast, but also, compared with the prior art method of directly cleaning the debris along the filter screen 215, the rotation method of the present invention can prevent the debris from being stuck in the pores on the filter screen 215, which is convenient for cleaning the filter screen 215.

[0077] like Figure 2-3 As shown, the concrete entering the guide hopper 111 will be drawn into the mixing sleeve 112 along the bottom of the guide hopper 111, and the drive motor 131 is started. The drive motor 131 drives the mixing paddle 113 to rotate through the drive shaft 132, so that the concrete in a larger area inside the mixing sleeve 112 is initially mixed, and the concrete before entering the feeding pipe 121 is prevented from being stratified or solidified inside the mixing sleeve 112, so as to ensure that the concrete poured in the specimen mold can reflect the real engineering characteristics;

[0078] like Figure 2-3 As shown, the driving shaft 132 drives the stirring paddle 113 to initially stir the concrete in the stirring sleeve 112, and also drives the driving gear 1331 to rotate. The driving gear 1331 drives the driven gear 1333 to rotate through the chain 1332. The driven gear 1333 drives the concrete at the inlet 1211 to enter the outlet 1212 along the feeding pipe 121 in a rotating and pushing manner through the spiral pushing paddle 122, thereby further stirring the concrete in the transfer process before pouring, further avoiding uneven distribution of the concrete during pouring, and ensuring that the concrete characteristics reflected by the test piece are more accurate.

[0079] The concrete transferred to the discharge port 1212 slides along the pouring pipe 123 into the specimen mold.
