Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a foundation compaction device. Background Technology

[0002] Grain reserve warehouses are specialized warehouses used to store grain and other agricultural products. Their main function is to ensure a stable grain supply, prevent grain shortages, and play a key role in market regulation. When constructing grain reserve warehouses, the foundations used for them need to be compacted, so compaction devices are required.

[0003] Chinese patent provides a building foundation compaction device, publication number CN222025013U, which includes a device base, an opening on the bottom surface of the device base, a mounting bracket fixedly connected to the upper surface of the device base, a first cylinder fixedly connected to the inner top wall of the mounting bracket, a pressure plate fixedly connected to the bottom end of the first cylinder, and a wear-resistant plate fixedly connected to the bottom surface of the pressure plate.

[0004] The aforementioned compaction device, through the cooperation of vertical plates, horizontal plates, a second cylinder, and a special-shaped bulldozer plate, can level the ground during movement, facilitating subsequent compaction and ensuring the compaction effect. With the installation bracket, the first cylinder, pressure plate, and wear-resistant plate work together to compact the foundation, making it relatively convenient to use. The high strength of the wear-resistant plate extends the device's service life, which is beneficial for its use. However, the motor remains connected during foundation compaction, which can transmit the compaction force to the motor, causing damage and shortening its lifespan. Utility Model Content

[0005] The purpose of this utility model is to provide a foundation compaction device to solve the problem that in existing compaction devices, the motor is always connected during foundation compaction, which will transmit the force generated by compaction to the motor, causing damage to the motor and shortening its service life.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-4 A foundation compaction device includes a base plate 1, a compaction mechanism 2 and a cleaning mechanism 3 at the top of the base plate 1, a roller mechanism fixedly installed on both sides of the bottom end of the base plate 1, and a handle fixedly connected to one side of the top end of the base plate 1.

[0024] See Figures 1-3 Furthermore, the compaction mechanism 2 includes a tamping hammer 201 inserted through the top of the base plate 1. Vertical plates 202 are fixedly connected to both sides of the top of the base plate 1 corresponding to the tamping hammer 201. Rotating shafts 203 are rotatably inserted through both vertical plates 202. Half-gears 204 are fixedly connected to the ends of the two rotating shafts 203 that are far apart from each other. Connecting plates 205 are fixedly connected to the ends of the two rotating shafts 203 that are close to each other. A guide post 206 is fixedly connected between the two connecting plates 205. A guide post 206 is fixedly connected to the top of the tamping hammer 201. The guide plate 207 has a guide hole 208 through it, and the guide post 206 is set in the guide hole 208. The two vertical plates 202 are respectively fixedly connected to the lower part of the corresponding rotating shaft 203 at their opposite ends. The driving ends of the two motors 209 are respectively fixedly connected to the first drive shaft 210 and the second drive shaft 211. The outer walls of the first drive shaft 210 and the second drive shaft 211 are fixedly connected to the full gears 212. The two full gears 212 and the two half gears 204 are meshed together.

[0025] Specifically, the tamping hammer 201 compacts the land used for the grain storage to prevent collapse. The vertical plate 202 limits the rotation of the rotating shaft 203, ensuring its stable rotation. The connecting plate 205 rotates the guide column 206, which in turn moves the guide plate 207, and consequently the tamping hammer 201. A synchronous controller controls the motor 209 to rotate synchronously, ensuring that the first drive shaft 210 and the second drive shaft 211 rotate synchronously, thus moving the two sides of the full-tooth... The wheel 212 rotates, causing the two half gears 204 to rotate synchronously. When the half gear 204 rotates 180 degrees, the guide post 206 is at the top. Due to rotational inertia, the guide post 206 can flip to the other side. At this time, the hammer 201 will quickly move down and act on the grain silo foundation through gravity to carry out the compaction operation until the half gear 204 contacts the full gear 212 again, thus performing repeated operations. Therefore, it is not necessary to always connect to the motor 209 during compaction, avoiding damage to the motor 209 and extending its service life.

[0026] Example 2

[0027] See Figure 1 , Figure 2 and Figure 4 Furthermore, based on Embodiment 1, the cleaning mechanism 3 includes a fixed plate 301 fixedly connected to the top of the base plate 1 on one side corresponding to the tamping hammer 201. Multiple fixed plates 301 are provided, and all of them are rotatably connected to the second drive shaft 211. A fixed shaft 302 is rotatably passed through the top of the base plate 1 on one side corresponding to the fixed plate 301. Cleaning rods 303 are fixedly connected to both sides of the bottom of the outer wall of the fixed shaft 302. A first bevel gear 304 is fixedly connected to the other end of the second drive shaft 211. A second bevel gear 305 is fixedly connected to the top of the fixed shaft 302. The second bevel gear 305 and the first bevel gear 304 are meshed together.

[0028] Specifically, the fixed plate 301 can limit the second drive shaft 211 to rotate stably, and the base plate 1 can limit the fixed shaft 302. When the fixed shaft 302 rotates, it can rotate the cleaning rod 303, thereby clearing away iron blocks or hard stones on the road surface, avoiding creating grooves at the bottom of the tamping hammer 201, and preventing it from affecting the subsequent compaction effect.

[0029] In actual operation, the motor 209 is first controlled by the synchronous controller to drive the first drive shaft 210 and the second drive shaft 211 to rotate synchronously, so that the full gear 212 can rotate synchronously. When the full gear 212 and the half gear 204 are meshed, the half gear 204 can be rotated. Since the half gear 204 is only half, the guide column 206 can be at the top when it rotates 180 degrees. At this time, due to the rotational inertia, the guide column 206 can continue to rotate, so it can be flipped. Through the gravity of the hammer 201, it can be moved down quickly to complete the compaction of the grain silo foundation. This avoids the motor 209 being in a connected state during compaction, prevents the force generated during compaction from being transmitted to the motor 209, avoids damage to the motor 209, and extends its service life.

[0030] Furthermore, the second drive shaft 211 rotates the first bevel gear 304, and the first bevel gear 304 rotates the second bevel gear 305, which can rotate the fixed shaft 302 and the cleaning rod 303. Therefore, it can clear away iron blocks or hard stones on the foundation, avoid causing dents at the bottom of the tamping hammer 201, and prevent affecting the subsequent compaction effect.

[0031] 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 the 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.
