Description

Technical Field

[0001] The utility model belongs to the technical field of dam construction, in particular to a dam filling and compacting device. Background Art

[0002] A dam refers to a dike that blocks water from a river, a water-blocking dike in a reservoir, a river, etc. Generally, a reservoir dam is mainly composed of a main dam, a secondary dam, a normal spillway, an emergency spillway, a new emergency spillway, a Lingzheng channel culvert and a power station. When building a dam, it is necessary to compact the area around the dam, so a compaction device is required. When a roller device is used for compaction, debris will stick to the roller, affecting the smoothness of the road surface.

[0003] Patent No. CN202222338225.0 provides a roadbed and pavement compacting device. By arranging a shock-absorbing mechanism and a shock-absorbing mechanism between the moving wheel and the main body, it avoids the direct rigid effect of the vibration generated by the operation of the device on the main body, thereby extending the service life of the main body. By arranging a scraper, impurities on the surface of the pressure roller can be scraped off, thereby ensuring the flatness of the pressure roller surface, and then ensuring the pavement compaction effect, solving the above-mentioned technical problems.

[0004] However, in actual application, there are still the following defects: the impurities stuck on the surface of the roller will be in lumps after being scraped off and fall to the ground. It is difficult to adhere to the soil layer below and it is easy to stick to the surface of the roller again, affecting the flatness and compaction effect of the roller. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a dam filling compaction device, and the technical solution adopted is as follows:

[0006] A dam filling and compacting device comprises a pressure roller, both ends of which are provided with a rotating shaft connected to a bracket, one end of the bracket is provided with a connecting ear seat connected to a tractor, a main rotating wheel is sleeved on one end of the pressure roller and located on the outside of the rotating shaft; a crushing box is installed in the bracket and on one side of the pressure roller, a crushing roller is installed inside the crushing box, one end of the crushing roller passes through the bracket, a slave rotating wheel is sleeved between the bracket and the crushing box and located on the outside of the crushing roller, and the slave rotating wheel is connected to the main rotating wheel through a transmission belt; a scraper is installed on the upper side of the crushing box and close to the pressure roller through bolts.

[0007] Furthermore, fixing columns for inserting into the bracket are provided on both sides of the crushing box, and two fixing columns are provided on each side, which are arranged up and down, so as to fix the crushing box without affecting the movement of the transmission belt.

[0008] Furthermore, sliding bearings are provided at the connection between the rotating shaft and the bracket, and at the connection between the crushing roller and the bracket.

[0009] Furthermore, a plurality of protrusions are arranged in a staggered manner inside the crushing box and outside the crushing roller, and the protrusions are used to knock and crush the impurities in the crushing box.

[0010] Furthermore, the diameter of the main rotating wheel is 3-5 times that of the slave rotating wheel, and the gear ratio is 3-5:1. When the pressure roller rotates one circle, it can drive the crushing roller to rotate 3-5 circles, thereby fully crushing the impurities in the crushing box.

[0011] Furthermore, a plurality of discharge ports for discharging crushed impurities are provided below the crushing box.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model can firstly scrape off the impurities adhering to the surface of the pressure roller through the scraper, and the impurities in blocks after scraping fall into the crushing box, and then the impurities in blocks are crushed by the crushing roller in the crushing box. The power of crushing comes from the rotation of the pressure roller, and the power is transmitted to the crushing roller through the setting of the transmission wheel and the transmission belt. The crushed impurities fall through the discharge port below the crushing box and are scattered on the soil layer below again. Under the rolling of the subsequent pressure roller, they can be fully bonded to the soil layer below and will not stick to the surface of the pressure roller again, thereby improving the compaction effect and rolling flatness.

[0020] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be described clearly and completely below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0021] As attached Figure 1-4 shown.

[0022] A dam filling compaction device includes a pressure roller 1, a rotating shaft 2 connected to a bracket 3 is provided at both ends of the pressure roller 1, a connecting ear seat 31 connected to a tractor is provided at one end of the bracket 3, a main rotating wheel is sleeved between the pressure roller 1 and the bracket 3 on one side and located on the outside of the rotating shaft 2, a crushing box 4 is installed in the bracket 3 and on one side of the pressure roller 1, and fixing columns 41 for inserting into the bracket 3 are provided on both sides of the crushing box 4, a crushing roller 5 is installed inside the crushing box 4, one end of the crushing roller 5 passes through the bracket 3, and a slave rotating wheel is sleeved between the bracket 3 and the crushing box 4 and located on the outside of the crushing roller 5, and the slave rotating wheel is connected to the main rotating wheel through a transmission belt 7.

[0023] A scraper 6 is installed above the crushing box 4 and on one side close to the pressure roller 1 through bolts, and the outer end of the scraper 6 is in contact with the outer surface of the pressure roller 1.

[0024] The connection between the rotating shaft 2 and the bracket 3 and the connection between the crushing roller 5 and the bracket 3 are both provided with sliding bearings.

[0025] The working process is as follows: through the connecting ear seat 31 in the bracket 3, the compacting device can be installed as a whole on the rear end of a tractor such as a tractor, so that it can drive the pressure roller 1 to roll the area that needs to be compacted. During the rolling process, the block impurities adhering to the surface of the pressure roller 1 will be scraped off by the scraper 6 and fall into the inside of the crushing box 4. There are several convex columns arranged in an alternating manner inside the crushing box 4 and on the outside of the crushing roller 5.

[0026] Since the diameter of the main rotating wheel on one side of the pressure roller 1 is 3-5 times that of the secondary rotating wheel on one side of the crushing roller 5, and the gear ratio is 3-5:1, when the pressure roller 1 rotates, under the action of the transmission belt 7, the crushing roller 5 will be driven to rotate rapidly, and the block impurities scraped out of the crushing box 4 will be crushed and scattered. The scattered impurities fall through the multiple discharge ports 42 opened at the bottom of the crushing box 4, and are scattered again on the soil layer below. Under the subsequent rolling of the pressure roller 1, they can be fully bonded to the soil layer below and will not stick to the surface of the pressure roller 1 again, thereby improving the compaction effect and rolling flatness.
