Technical Field

[0001] This utility model belongs to the field of mixer technology, and in particular relates to a small cement mixer. Background Technology

[0002] A cement mixer is a device that mixes cement, sand, gravel, water, and other raw materials evenly, and it is widely used in the construction industry. Currently common cement mixers are relatively large in size and weight. When the amount of concrete to be mixed is small, or when concrete needs to be mixed upstairs, transporting the cement mixer is time-consuming and labor-intensive. Furthermore, cement mixers are difficult to navigate through narrow staircases and require hoisting, and a small amount of concrete inevitably spills during the transfer from the cement mixer to the cement bucket. Utility Model Content

[0003] The purpose of this invention is to provide a small cement mixer that allows for direct mixing of concrete by rotating the cement bucket when the demand for concrete is relatively small, saving time and effort.

[0004] The technical approach adopted in this utility model is as follows: a small cement mixer, including a vertically arranged bucket body and a cover body covering the top of the bucket body, a cement bucket is independently and vertically arranged inside the bucket body, a mixing component is independently arranged inside the cement bucket, the mixing component includes a vertically arranged blade fixing rod, the top end of the blade fixing rod is installed on the cover body, and a mixing blade is installed on the blade fixing rod located inside the cement bucket.

[0005] A transmission assembly is installed at the bottom of the cement bucket. The transmission assembly includes a vertically arranged rotating shaft, a rotating block is fixed at the upper end of the rotating shaft, and a drive assembly for driving the rotating shaft to rotate is connected to the lower end of the rotating shaft.

[0006] The corresponding rotating block has a groove at the center of the outer side wall at the bottom of the cement bucket for inserting the rotating block. When the rotating block rotates, it can drive the cement bucket to rotate together.

[0007] Furthermore, a partition is provided horizontally between the bottom of the cement bucket and the inner bottom surface of the bucket body. The partition is fixed on the inner side wall of the bucket body. A through hole is provided on the partition, and a bearing that cooperates with the rotating shaft is fixed in the through hole.

[0008] Furthermore, a receiving space is formed between the partition and the inner bottom surface of the barrel. The drive assembly is installed in the receiving space. The drive assembly includes a motor, the power output end of the motor is connected to a reducer, the power input end of the reducer is connected to the power output end of the motor, and the power output end of the reducer is connected to the lower end of the rotating shaft.

[0009] Furthermore, the cross-section of the blade fixing rod is square.

[0010] Furthermore, the cover has a square hole through which the blade fixing rod passes independently and is connected vertically, and a stop block is installed at the upper end of the blade fixing rod.

[0011] Furthermore, one end of the lid is hinged to the top of the barrel via a hinge.

[0012] Furthermore, a base is horizontally arranged below the barrel body, and a connecting seat is fixed to the rear side of the bottom of the barrel body. The connecting seat and the base are hinged together by a hinge. A horizontally arranged lifting seat is installed on the outer side wall of the front side of the barrel body.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0033] like Figure 4 As shown, a cuboid with a square cross-section is manufactured by casting. A frustum-shaped cavity is formed inside the cuboid. A cuboid-shaped cavity is located in the lower part of the cuboid. The bottom of the frustum-shaped cavity is separated from the cuboid cavity by a partition. A through-hole is formed at the center of the partition, and a bearing 8 is installed inside the through-hole. Figure 13 As shown, two symmetrical connecting seats 1.1 are welded to the bottom right edge of the barrel body 1, as follows. Figure 12 As shown, a lifting seat 1.2 is welded to the outer left side of the barrel 1.

[0034] After cutting and smoothing an aluminum alloy sheet, it is bent into two handles. 5. For example Figure 1 As shown, handles 5 are welded to the left and right sides near the top of the outer side of the barrel body 1.

[0035] Prepare plastic and process it into cement bucket 2 using a mold, such as Figure 1 and Figure 5 As shown, the cement bucket is shaped like a truncated cone, with an outward flange at the top and a square-shaped groove at the center of its bottom outer wall.

[0036] Based on the dimensions of the opening at the top of the barrel 1, a lid 3 is machined from aluminum alloy. The lid 3 perfectly covers the barrel 1. Figure 14 As shown, there is a square-shaped protrusion at the center of the cover 3, and a square hole at the very center of the protrusion.

[0037] Transmission component 7 is machined from aluminum alloy. For example... Figure 6 and Figure 7 As shown, the transmission component 7 is a square rotating block, and a structure for connecting the rotating shaft is provided at the bottom center of the rotating block to ensure that the rotating shaft can be fitted with the bearing 8. The rotating block can be tightly fitted with the square groove at the bottom of the cement bucket 2. During the rotation of the rotating block, the cement bucket 2 is driven to rotate, and the rotating block will not fall off the groove.

[0038] The blade retaining rod 6.1 is machined from aluminum alloy. For example... Figure 8 and Figure 9 As shown, the blade fixing rod 6.1 has a rectangular long rod with one end beveled and sharpened, and a square stop is installed at the other end; a threaded through hole is machined at the lower end of the blade fixing rod 6.1 near the sharpened part.

[0039] The stirring blades 6.2 are machined from aluminum alloy. Figure 10 and Figure 11 As shown, the structure of the stirring blade 6.2 consists of four blades bent at 90 degrees distributed around a hollow square tube, with mounting holes that connect the front and back of the tube.

[0040] Prepare square aluminum tubing and four casters. For example... Figure 12 As shown, four square tubes are welded end to end to form a frame. The size of the frame should be such that the barrel 1 can be placed on top of the frame. Two lifting lugs are symmetrically welded to one end of the upper surface of the frame. Pivots are independently inserted into the holes opposite to the lifting lugs. Four casters are installed at the bottom to form a base 9.

[0041] Place the base 9 horizontally, and place the barrel 1 on the base 9. The connecting seat 1.1 on the barrel 1 is coaxial with the lifting lug hole on the base 9 and is inserted into the pivot for hinge connection.

[0042] Place bucket 1 upright, as follows: Figure 1As shown, a motor 11 is installed in the cuboid cavity of the lower part of the barrel 1. Specifically, a door can be provided on the side wall of the barrel 1 to facilitate the installation of the motor 11 and the reducer 10. The power output end of the motor 11 is connected to the power input end of the reducer 10, as shown. Figure 1 As shown, the bearing 8 is installed into the through hole of the partition; the rotating shaft of the transmission assembly 7 is passed through the bearing hole from top to bottom, and the power output end of the reducer 10 is connected to the lower end of the rotating shaft of the transmission assembly; the cement bucket 2 is placed into the bucket body 1, and its bottom groove is embedded in the rotating block of the transmission assembly 7, forming a clearance fit.

[0043] The cover 3 is hinged to the barrel 1 via hinge 4. A buckle can also be installed on the side of the barrel 1 opposite to hinge 4 to prevent the cover 3 from being opened after it is closed. The blade fixing rod 6.1 is passed through the square hole of the cover 3, and then the stirring blade 6.2 is fitted onto the blade fixing rod 6.1 and fixed with a countersunk bolt passing through the mounting hole and threaded through hole. Figure 2 As shown, the bottom cylinder body of the hydraulic cylinder 12 is hinged to the base 9, and the top of the piston rod is hinged to the lifting seat 1.2. The end of the piston rod of the hydraulic cylinder 12 can be configured as a hemispherical shape.

[0044] When using, such as Figure 3 As shown, the hydraulic cylinder 12 is used to lift the barrel 1, tilting it at a certain angle. The mixing component 6 is lifted and the cover 3 is opened. A suitable amount of raw materials such as cement, sand, gravel, and water are added into the cement barrel 2. Then, the cover 3 is closed and the mixing component 6 is inserted. The motor 11 is started to mix. After mixing, the mixing component 6 is pulled out and the cover 3 is opened. The cement barrel 2 is lifted out. After use, the piston rod of the hydraulic cylinder 12 is retracted and the barrel 1 is leveled.

[0045] This small cement mixer is compact and lightweight. When the demand for concrete is small, the inclined cement bucket 2 can be rotated directly to mix the concrete, saving time and effort. When it is necessary to apply concrete or other materials upstairs but there is no hoisting equipment, the mixer can be easily moved from the stairs, eliminating the need to mix downstairs and then manually transport the concrete upstairs, saving time and effort, and greatly avoiding concrete spillage during transportation, thus saving raw materials.
