Description

Technical Field

[0001] This utility model relates to the field of mortar transport carts for construction sites, and in particular to a cement mortar holding device. Background Technology

[0002] Cement at construction sites is transported via dump trucks, which typically employ hydraulic lifting and tipping mechanisms. The material is dumped by rotating the hopper around a hinged shaft. However, due to the solid-liquid two-phase flow caused by the aggregate's own weight settling, a dynamic compaction effect occurs at the bottom of the hopper, leading to adhesion and caking. In actual operation, 8-12% of the material remains stuck to the walls even after the hopper is reset, requiring manual intervention and significantly reducing transport efficiency. The continuous ineffective transport of residual material results in approximately 15% of the traction power unit's energy consumption being wasted, and an effective volume reduction rate of 18%-22% per operating cycle. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a cement mortar holding device to solve the problem of a large amount of mortar accumulating on the walls of cement mortar transport dump trucks on construction sites, preventing complete unloading.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A cement mortar holding device includes a frame, on which a hopper is rotatably mounted. The hopper is rotatable along its own axis and has an arc-shaped inner cavity extending along the axis. A horizontally arranged scraper is provided on the inner side of the hopper and is fixed to the frame. The scraper fits against the arc-shaped inner cavity, and the contact trajectory between the scraper and the arc-shaped inner cavity forms a continuous scraping path during the hopper's rotation. A material discharge channel is formed in the middle of the frame directly opposite the hopper. The hopper is driven to rotate by a rotating component.

[0006] Optionally, rotating sleeves are symmetrically fixed on the outer wall of the hopper, with the axis of the rotating sleeves coinciding with the axis of the hopper. Side support bars are symmetrically fixed on the top of the frame, and the two rotating sleeves are rotatably connected to the two side support bars respectively.

[0007] Optionally, the scraper is symmetrically fixed with connecting shafts at both ends. The axis of the connecting shafts coincides with the axis of the hopper. The connecting shafts are rotatably connected to the hopper and pass through the hopper and the rotating sleeve. The opposite ends of the two connecting shafts are respectively fixed to the opposite outer walls of the two side support bars.

[0008] Optionally, the rotating assembly includes an arc-shaped gear ring fixed at the middle position of the outer wall of the hopper. The axis of the tooth distribution circle of the arc-shaped gear ring coincides with the axis of the hopper. A drive shaft is rotatably mounted at the middle of the frame near the scraper. A gear is fixed at the middle of the drive shaft. The gear meshes with the arc-shaped gear ring. A power device for driving the drive shaft to rotate is fixed on the top surface of the frame.

[0009] Optionally, the power unit includes a motor fixed to the top surface of the frame, with sprockets fixed to both the output end of the motor and the end of the drive shaft, and a chain connecting the two sprockets.

[0010] Optionally, the hopper is configured as a semi-cylindrical shell.

[0011] Optionally, the hopper is configured as a hemispherical shell.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This utility model provides a scraper on the inside of the hopper and sets the hopper in a semi-cylindrical or hemispherical shell shape. During the process of driving the hopper to flip and discharge material, the scraper can automatically and synchronously scrape the inner wall of the hopper, so that the material accumulated on the inner wall of the hopper is separated from the hopper, avoiding the continuous hanging of material on the wall. No manual cleaning is required, thus avoiding waste of transportation capacity and preventing the reduction of transportation volume.

[0014] This invention sets the hopper in a semi-cylindrical or hemispherical shell shape, so that while driving the hopper to flip and discharge material, it can automatically perform scraping action without the need for additional power equipment to drive the scraper, thus saving equipment manufacturing and operation and maintenance costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, please refer to Figures 1 to 3 This embodiment provides a cement mortar holding device, including a frame 1. A hopper 2 is rotatably mounted on the top of the frame 1. The hopper 2 is generally set in a semi-cylindrical shell shape. Rotating sleeves 3 are symmetrically fixed on the outer wall of the hopper 2. The axis of the rotating sleeves 3 coincides with the axis of the hopper 2. Side support bars 4 are symmetrically fixed on the top of the frame 1. The two rotating sleeves 3 are rotatably connected to the two side support bars 4 respectively. The side support bars 4 support the hopper 2, so that the hopper 2 is suspended above the frame 1 and rotatably connected to the frame 1.

[0022] One end of the entire frame 1 is fixed with a tow hook, which can be connected to the power unit to drive the frame 1 to move and carry out the work of loading and transporting cement mortar. After being transported to the designated position, the material can fall into the designated position through the material drop channel formed in the middle of the frame 1, which is directly opposite the hopper 2. During the hopper 2's overturning process, the material can pass through the material drop channel and fall into the designated position.

[0023] A horizontally arranged scraper 5 is provided on the inner side of the hopper 2. A connecting shaft 6 is symmetrically fixed at both ends of the scraper 5. The axis of the connecting shaft 6 coincides with the axis of the hopper 2. The connecting shaft 6 is rotatably connected to the hopper 2 and passes through the hopper 2 and the rotating sleeve 3. The opposite ends of the two connecting shafts 6 are respectively fixed to the opposite outer walls of the two side support bars 4. The rotating sleeve 3 is hollow and not connected to the connecting shaft 6. The scraper 5 fits against the arc-shaped inner cavity of the hopper 2. The contact trajectory between the scraper 5 and the arc-shaped inner cavity forms a continuous scraping path during the hopper 2's tumbling process.

[0024] When the frame 1 reaches the designated position for material unloading, the drive hopper 2 is flipped, while the scraper 5 remains fixed and does not move, causing relative displacement between the hopper 2 and the scraper 5. The flipping of the hopper 2 allows the material to be unloaded, and the inner wall of the hopper 2 is gradually scraped by the scraper 5, so that the accumulated residual cement mortar is scraped off by the scraper 5, avoiding residue, reducing the increase in transport capacity and the reduction in subsequent single transport volume.

[0025] An arc-shaped gear ring 7 is fixed at the middle of the outer wall of the hopper 2. The axis of the tooth distribution circle of the arc-shaped gear ring 7 coincides with the axis of the hopper 2. A drive shaft 8 is rotatably mounted at the middle of the frame 1 near the scraper 5. A gear 9 is fixed at the middle of the drive shaft 8. The gear 9 meshes with the arc-shaped gear ring 7. A motor 10 is fixed on the top surface of the frame 1. A sprocket 12 is fixed at the output end of the motor 10 and the end of the drive shaft 8. A chain 11 is connected between the two sprockets 12. For the hopper 2 to tilt, the drive motor 10 rotates, which in turn causes the drive shaft 8 to rotate through the chain 11 and sprocket 12, driving the gear 9 to rotate, which in turn causes the arc-shaped gear ring 7 to rotate, thereby causing the hopper 2 to tilt and tip.

[0026] Example 2, please refer to Figure 4 The difference between this embodiment and the first embodiment is that the hopper 2 is set in a hemispherical shell shape, providing another form of hopper 2. When this type of hopper 2 is flipped, the scraper 5 can also automatically scrape off the residual material accumulated inside during the flipping process of the hopper 2.

[0027] In summary, this invention features a fixed scraper 5 on the inner wall of the hopper 2. The hopper 2 adopts a semi-cylindrical or hemispherical shell structure and rotates around its axis. When the hopper 2 tilts to unload, the scraper 5 moves relative to the arc-shaped inner cavity, simultaneously scraping away adhering materials, eliminating the need for manual cleaning, and avoiding increased transportation costs and reduced transport capacity. This structure achieves self-cleaning through motion linkage, eliminating the need for an additional drive system and effectively reducing equipment manufacturing and maintenance costs.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
