Description

Technical Field

[0001] This utility model relates to the field of building block manufacturing technology, and in particular to a casting device for building blocks. Background Technology

[0002] Concrete blocks are prefabricated building materials made primarily from cement, aggregates (such as sand and stone), and water through processes such as mixing, molding, and curing. They are characterized by high strength, good durability, and convenient construction, and are widely used in construction projects such as walls, fences, and retaining walls.

[0003] The pouring of building blocks typically requires vibration to ensure the concrete is dense and uniform, and to eliminate air bubbles. Blocks that have not been vibrated may exhibit defects such as honeycombing and voids, leading to reduced strength, decreased durability, and even affecting appearance. Vibration effectively improves the density and overall performance of the blocks, ensuring they meet engineering requirements; therefore, vibration is a crucial step in block production.

[0004] A search revealed that Chinese utility model patent CN221892223U discloses a casting device for manufacturing building blocks, including a molding device. The molding device includes a casting platform, with a mold body fixedly connected to the top of the casting platform and a pushing mechanism fixedly connected to the bottom of the casting platform. This application uses a plug to allow material in the casting box to flow into the mold for casting building blocks. However, the device does not vibrate the concrete during the casting process, making it difficult to guarantee the quality of the formed product. Utility Model Content

[0005] In view of the above-mentioned prior art, the present invention provides a casting device for building blocks, and the main technical problem to be solved is how to ensure the quality of the formed product.

[0006] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0007] A casting device for building blocks includes a hopper and a base. The hopper is used to hold concrete and is equipped with a stirring rod, a spiral blade, and a drive mechanism. The base is equipped with a cam and a material trough for placing the casting mold. The drive mechanism is used to drive the stirring rod, the spiral blade, and the cam to rotate. The stirring rod agitates the concrete to homogenize the material by rotating. The spiral blade transports the concrete by rotating to assist in material discharge. The cam strikes the material trough by rotating to induce the casting mold to oscillate and vibrate.

[0008] Furthermore, a material cylinder is fixedly connected to one side of the top of the base, a material box is fixedly connected to the top of the material cylinder, a partition is fixedly connected inside the material cylinder, a first through hole is opened in the middle of the partition, and a connecting shaft is rotatably connected to the partition at the first through hole.

[0009] Furthermore, a second through hole is provided on one side of the top of the material box, and the top of the connecting shaft extends to the outside of the material box at the second through hole. Several collars are fixedly connected to the outside of the rod body in the material box at the connecting shaft, and the stirring rod is fixedly connected to the outside of the collars.

[0010] Furthermore, the top of the hopper is fixedly connected to the outer part of the second through hole, and the drive mechanism includes a motor, which is fixedly connected in the housing, and the bottom end of the motor's output shaft is fixedly connected to the connecting shaft.

[0011] Furthermore, a third through hole is provided at the top of the base on the inner side of the barrel, and the bottom end of the connecting shaft extends into the base through the third through hole. The cam is connected by a key to the outside of the rod body in the base of the connecting shaft.

[0012] Furthermore, the spiral blades are fixedly connected to the outside of the rod body inside the barrel, with the connecting shaft located at the top of the partition. A discharge port is opened on one side of the barrel at the top of the partition, and a material pipe is fixedly connected to the discharge port of the barrel, with a valve installed in the material pipe.

[0013] Furthermore, the top of the material box has an opening on one side of the material cylinder, and a fixing frame is fixedly connected to the material box at the opening. The material trough is located inside the fixing frame, and several springs are fixedly connected at equal intervals between the material trough and the inner wall of the fixing frame.

[0014] Furthermore, several bases are fixedly connected at equal intervals to the bottom of the material trough on the inner wall of the bottom of the base. Each base includes a pad and a ball. The pad is fixedly connected to the base. A spherical groove is opened at the top of the pad. The ball is located in the spherical groove and is tangent to the bottom wall of the material trough.

[0015] Furthermore, several support rods are fixedly connected at equal intervals between the material box and the base on the side away from the material cylinder. A feed inlet is provided on one side of the top of the material box, and a cover plate is provided at the feed inlet on the top of the material box.

[0016] Furthermore, several threaded through holes are equidistantly opened at the top outer side of the material trough. Bolts are threadedly connected to the material trough at the threaded through holes. A clamp is fixedly connected to one end of the bolt in the material trough, and a wrench is fixedly connected to the other end of the bolt.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. When using this device to pour blocks, the rotation of the mixing rod can homogenize the concrete, while the rotation of the spiral blades can assist in the discharge of concrete, thus ensuring smooth and convenient discharge during the pouring process; at the same time, the rotation of the cam can continuously impact the material trough, causing the material trough and the mold placed inside it to swing and vibrate, thereby achieving a vibration effect on the concrete injected into the mold, thus ensuring the quality of the poured blocks.

[0019] 2. By setting up springs and bases, when the material trough is impacted by the cam and vibrates, the springs can expand the range of motion of the material trough through their own elasticity and quickly return to their original shape after movement, so that the concrete can be evenly distributed in the mold through shaking. In this process, the base can provide support for the material trough without affecting its movement through ball bearings, so as to ensure the stability of the material trough and reduce the friction during its movement, so that its shaking vibration can be generated smoothly.

[0020] 3. By setting bolts on the base, the bolts can be rotated by shaking a wrench, thereby adjusting the position of the clamping plate to fix the mold placed in the material trough. This not only ensures the smoothness of the pouring process by maintaining the stability of the mold, but also allows the device to be used with molds of different sizes, so that the device can be used to pour different types of blocks.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0027] Example 1

The material box 1 is provided with a stirring rod 2, a spiral blade 5 and a drive mechanism. The base 12 is provided with a cam 8 and a material trough 10 for placing the casting mold. The drive mechanism is used to drive the stirring rod 2, the spiral blade 5 and the cam 8 to rotate. The stirring rod 2 stirs the concrete to homogenize the material by rotating. The spiral blade 5 transports the concrete by rotating to assist in material discharge. The cam 8 hits the material trough 10 by rotating to cause the casting mold to swing and vibrate, thereby achieving the effect of vibration during the concrete casting process.

[0029] Preferably, the top of the material box 1 is fixedly connected to the housing 17 outside the second through hole, and the drive mechanism includes a motor 16, which is fixedly connected in the housing 17, and the bottom end of the output shaft of the motor 16 is fixedly connected to the connecting shaft 4.

[0030] When using this device to cast building blocks, concrete raw materials can be loaded into the material box 1, then the casting mold can be placed in the material trough 10, and then the motor 16 can be started.

[0031] Preferably, a material cylinder 7 is fixedly connected to one side of the top of the base 12, and a material box 1 is fixedly connected to the top of the material cylinder 7. A partition 6 is fixedly connected inside the material cylinder 7, and a first through hole is opened in the middle of the partition 6. A connecting shaft 4 is rotatably connected to the partition 6 at the first through hole. A second through hole is opened on one side of the top of the material box 1, and the top of the connecting shaft 4 extends to the outside of the material box 1 at the second through hole. Several collars 3 are fixedly connected to the outside of the rod body in the material box 1 at the connecting shaft 4. A stirring rod 2 is fixedly connected to the outside of the collars 3. There are three collars 3. The stirring rod 2 is "E" shaped, and the three landing points of the stirring rod 2 are fixedly connected to the three collars 3 respectively. A third through hole is opened on the inner side of the material cylinder 7 at the top of the base 12, and the bottom end of the connecting shaft 4 extends into the base 12 at the third through hole. A cam 8 is connected by a key to the outside of the rod body in the base 12 at the connecting shaft 4. The cam 8 can be an eccentric wheel or an elliptical shape.

[0032] The motor 16 can drive the mixing rod 2, the spiral blade 5 and the cam 8 to rotate through the connecting shaft 4. The rotation of the mixing rod 2 can agitate the concrete to achieve a homogeneous effect, while the rotation of the spiral blade 5 can transport the concrete from top to bottom to assist in the discharge.

[0033] Preferably, the spiral blade 5 is fixedly connected to the outside of the rod body of the connecting shaft 4 located in the material cylinder 7. The spiral blade 5 is located at the top of the partition plate 6. A discharge port is opened on one side of the material cylinder 7 at the top of the partition plate 6. A material pipe 9 is fixedly connected to the material cylinder 7 at the discharge port. A valve is provided in the material pipe 9. The discharge end of the material pipe 9 faces the material trough 10 to ensure that the material discharged from its interior can accurately fall into the mold.

[0034] At this point, opening the valve in material pipe 9 allows the material to flow out and be injected into the mold, achieving the effect of block casting.

[0035] Preferably, the top of the material box 1 has an opening on one side of the material cylinder 7, and a fixing frame 14 is fixedly connected to the material box 1 at the opening. The material trough 10 is located inside the fixing frame 14, and several springs 13 are fixedly connected at equal intervals between the material trough 10 and the inner wall of the fixing frame 14.

[0036] During the above process, the rotation of cam 8 can continuously impact the material trough 10, causing it to sway and vibrate under the elastic force of spring 13, thereby vibrating the concrete injected into the mold and ensuring the quality of the finished block.

[0037] Preferably, a plurality of bases 11 are fixedly connected at equal intervals to the bottom inner wall of the base 12 at the bottom of the material trough 10. Each base 11 includes a pad 1101 and a ball 1102. The pad 1101 is fixedly connected to the base 12. A spherical groove is provided at the top of the pad 1101. The ball 1102 is located in the spherical groove and is tangent to the bottom wall of the material trough 10.

[0038] During the swaying movement of the trough 10, the base 11 can support it, and the ball bearing 1102 can offset the friction generated by the relative movement between the two by its own rotation. Therefore, the base 11 can provide stable support for the trough 10 without affecting its movement, so as to ensure that its swaying and vibration are generated smoothly.

[0039] After the casting is completed, the valve in the material pipe 9 can be closed first, and then the mold can be removed from the material trough 10. After that, a new mold can be replaced to continue the casting and manufacturing of blocks.

[0040] Preferably, a number of support rods 15 are fixedly connected at equal intervals between the material box 1 and the base 12 on the side away from the material cylinder 7. A feed inlet is provided on one side of the top of the material box 1, and a cover plate is provided at the feed inlet on the top of the material box 1.

A clamping plate 20 is fixedly connected to one end of the bolt 18 in the material trough 10, and a wrench 19 is fixedly connected to the other end of the bolt 18.

[0043] After the mold is placed into the material trough 10, the bolt 18 can be rotated by turning the wrench, thereby adjusting the position of the clamping plate 20 to clamp and fix the mold. This not only maintains the stability of the mold and ensures the smooth progress of the pouring process, but also allows the material trough 10 to fix different types of molds, making the device suitable for pouring different types of building blocks, thus expanding the applicability of the device.
