Description

Technical Field

[0001] This utility model relates to the field of brick making machine technology, specifically to a brick making machine material cart with controllable material feeding density. Background Technology

[0002] A brick-making machine is a mechanical device used to press raw materials (such as soil, clay, cement, sand, cinder, slag, etc.) into bricks of fixed shapes and sizes through pressure and vibration. It includes a main frame, hydraulic system, vibration system, mold, and control system. Some machines are also equipped with a plate feeder and a brick output system. The main frame provides support for the entire brick-making machine and provides power through the hydraulic system. After the material is put into the mold, it is placed on the vibration system to make the material more compact. Then, pressure is applied to press the material firmly into the mold, and after drying, bricks are formed. Various building bricks can be produced efficiently and with high quality through mechanization.

[0003] The brick-making machine material cart is an automated bridge connecting raw material preparation and brick pressing. Its core task is to feed the mold accurately, quickly, and evenly. It consists of a frame, a walking mechanism, and a power system. The hopper sends the material into the material cart, and the material cart evenly feeds the material into the mold. It is a key component to ensure the efficient, stable, and high-quality operation of a modern brick-making production line.

[0004] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: When the existing material cart is in use, the material on the hopper falls directly and is fed directly into the mold through the material cart. However, when producing bricks of different densities, the amount of material fed into the mold can only be controlled by controlling the feeding speed of the hopper, thereby controlling the density of the material. The operation is relatively cumbersome. Moreover, when the feeding speed of the hopper is uneven, it is easy to cause uneven filling of the mold. Some molds have more material and some molds have less material, resulting in uneven material in the mold and a high scrap rate. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a brick-making machine material cart with controllable density and uniform material distribution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a brick-making machine material cart with controllable material feeding density, comprising a frame and several movable wheels movably engaged and installed on the side wall of the frame. The frame is provided with a drive gear, and a rack is also slidably provided in the frame and meshing with the drive gear. A rake frame is provided at the end of the rack. A density adjustment device is detachably provided on the inner wall of the frame above the rake frame. The density adjustment device includes two symmetrically distributed fixed plates detachably installed on the inner wall of the frame above the rake frame and several slots integrally formed on the fixed plates. A first dispersing frame is detachably provided between the two fixed plates and engages with the inner wall of the slot. A second dispersing frame is also provided between the two fixed plates on one side of the first dispersing frame and engages with the inner wall of the slot.

[0007] A further improvement is that a partition plate is provided in the middle section of the frame.

[0008] A further improvement is that both the top surface of the first distribution frame end and the top surface of the second distribution frame end are provided with locking blocks.

[0009] A further improvement is that both the first and second distribution frames are inverted V-shaped frame structures.

[0010] A further improvement is that a scraper is also provided at the lower end of the second dispersing frame.

[0011] A further improvement is that the inner wall of the frame is also equipped with a cylinder seat.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When using this utility model, before the material is laid, the distance between the first and second dispersing frames can be adjusted according to the required density. When a higher density of raw materials is required, the distance between the first and second dispersing frames can be larger, so that during the laying process, the raw materials falling from the hopper can fall into the mold in large quantities through the gap between the first and second dispersing frames, resulting in a higher density of material in the mold after laying. When a lower density is required, the distance between the first and second dispersing frames can be adjusted to be smaller, so that when the material falls into the gap between the first and second dispersing frames, it can be blocked, and only a small portion of the material can pass through, thereby reducing the density of material in the mold after laying. During the laying process, the material will first fall between the two dispersing frames and then fall into the mold. Therefore, when the hopper feed is uneven, the remaining material between the first and second dispersing frames can be used to evenly spread the material, improving the uniformity of the laying.

Detailed Implementation

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a brick-making machine material cart with controllable material feeding density, including a frame 1 and several movable wheels 2 movably engaged and installed on the side wall of the frame 1. A drive gear 32 is provided inside the frame 1, and a rack 31 slidably connected to the drive gear 32 is also provided inside the frame 1. A rake frame 3 is provided at the end of the rack 31. A density adjustment device 5 is detachably provided on the inner wall of the frame 1 above the rake frame 3. The density adjustment device 5 includes two symmetrically distributed fixed plates 51 detachably installed on the inner wall of the frame 1 above the rake frame 3, and several slots 52 integrally formed on the fixed plates 51. A first dispersion frame 53 is detachably provided between the two fixed plates 51 and engages with the inner wall of the slots 52. A second dispersing frame 54, located on one side of the first dispersing frame 53, is also provided between the fixed plates 51 and the first dispersing frame 53. In use, the distance between the first dispersing frame 53 and the second dispersing frame 54 is first adjusted according to the required material density. Then, the hopper containing the material is installed on the frame 1, and the moving wheels 2 are placed on the track above the mold, allowing it to be guided to move along the track. An external drive device is then installed on the drive gear 32, allowing it to rotate in both directions. The hopper can then be opened, and the frame 1 is moved by the moving wheels 2. The material output from the hopper will first fall between the first dispersing frame 53 and the second dispersing frame 54. When a higher material density is required, the first dispersing frame 53 can be... The distance between the first and second dispersing frames 53 and 54 is relatively large. Therefore, during the material feeding process, a large amount of raw material falling from the hopper can fall onto the mold through the gap between the first and second dispersing frames 53 and 54, resulting in a high density of material inside the mold after feeding. When a lower density is needed, the distance between the first and second dispersing frames 53 and 54 can be adjusted to be smaller. This prevents material from falling into the gap between the first and second dispersing frames 53 and 54, allowing only a small portion of material to pass through, thus reducing the material density inside the mold after feeding. Adjusting the distance between the first and second dispersing frames 53 and 54 simply requires moving either the first or second dispersing frame 53 from the clamp. Pull out of the slot 52 and insert it into the corresponding slot 52 with the required gap width. The slot 52 can be a square slot so that it can fit the square ends of the first dispersing frame 53 and the second dispersing frame 54. Then, start the external drive device connected to the drive gear 32 so that the drive gear 32 can rotate forward and backward, thereby driving the rack 31 to move back and forth, thereby causing the rake frame 3 to reciprocate and push the material in the mold to flatten it. Then the material can be distributed. During the distribution process, the material will first fall between the two dispersing frames and then fall into the mold. In addition, when the material feeding in the hopper is uneven, the remaining material between the first dispersing frame 53 and the second dispersing frame 54 can be used to distribute the material evenly and improve the uniformity of the distribution. The frame 1 is equipped with a partition plate 4 in the middle section, which helps to separate the internal space of the frame 1 and prevents the material from falling into the rear during the fabrication process and affecting the movement of the drive gear 32 and rack 31. Both the top surface of the first dispersion frame 53 and the top surface of the second dispersion frame 54 are provided with locking blocks 531, which helps to prevent the first dispersion frame 53 and the second dispersion frame 54 from being subjected to downward impact force during operation and causing excessive falling and detachment from the fixing plate 51, making the use more stable. Both the first dispersion rack 53 and the second dispersion rack 54 are inverted V-shaped rack structures, which are beneficial to the material falling into the first dispersion rack 53 and the second dispersion rack 54. The inverted V-shaped rack structure guides the material to fall to both sides, preventing the material from accumulating and remaining on the first dispersion rack 53 and the second dispersion rack 54. The lower end of the second dispersing frame 54 is also equipped with a scraper 55, which is beneficial to scrape the uneven material on the mold during the movement of the material cart, so that the bricks after molding are more flat. The inner wall of the frame 1 is also provided with a cylinder seat 33, which is convenient for mounting the cylinder through the cylinder seat 33. The cylinder is connected to the camshaft and the drive gear 32 through the cylinder, so that it can rotate in both directions. The cylinder and the camshaft are existing technologies and will not be described in detail here.

[0017] The working principle of this utility model is as follows: When using this utility model, the distance between the first dispersing frame 53 and the second dispersing frame 54 is first adjusted according to the required material density. Then, the hopper containing the material is installed on the frame 1, and the moving wheels 2 are placed on the track above the mold, allowing it to move along the track. Subsequently, an external drive device is installed on the drive gear 32, allowing it to rotate in both directions. Then, the hopper can be opened, and the frame 1 is moved by the moving wheels 2. The material output from the hopper will first fall between the first dispersing frame 53 and the second dispersing frame 54. When a higher material density is required, the distance between the first dispersing frame 53 and the second dispersing frame 54 can be larger. Therefore, during the material distribution process, the material falling from the hopper can fall into the mold in large quantities through the gap between the first dispersing frame 53 and the second dispersing frame 54, resulting in a higher material density inside the mold after distribution. When a lower density is required, the distance between the first dispersing frame 53 and the second dispersing frame 54 can be increased. The smaller distance between the first and second dispersing frames 53 and 54 allows the material to be blocked when it falls into the gap between them, so that only a small portion of the material can pass through. This reduces the material density in the mold after the material is laid. When adjusting the distance between the first and second dispersing frames 53 and 54, simply pull the first or second dispersing frame 53 out of the slot 52 and insert it into the corresponding slot 52 with the required gap width. Then, start the external drive device connected to the drive gear 32 to make the drive gear 32 rotate forward and backward, thereby driving the rack 31 to move back and forth. This causes the rake frame 3 to reciprocate and push the material in the mold to flatten it. The material is then laid. During the laying process, the material will first fall between the two dispersing frames and then fall into the mold. Even if the material feeding from the hopper is uneven, the remaining material between the first and second dispersing frames 53 and 54 can be used to evenly spread the material and improve the uniformity of the material.
