Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] A mud scraping device, such as Figure 1-Figure 5 As shown, it includes a mounting arm 1, a swing arm 2 and a scraper mechanism. The swing arm 2 is connected to the bottom end of the mounting arm 1 and the swing arm 2 rotates relative to the connection with the mounting arm 1. A connecting piece is provided at one end of the swing arm 2, and a scraper mechanism is provided at the other end. The connecting piece and the scraper mechanism are respectively provided on both sides of the connection between the swing arm 2 and the mounting arm 1. An elastic supporting mechanism 3 is provided between the connecting piece and the mounting arm 1. The elastic supporting mechanism 3 pushes the connecting piece in a direction away from the mounting arm 1, thereby driving the swing arm 2 to rotate around the direction of the mounting arm 1, and then the scraper mechanism is moved closer to the soil crushing and pressing roller device, so that the scraper mechanism can play a better mud scraping effect.

[0026] As a specific example, a swing arm connecting hole is provided at the lower end of the mounting arm 1, the swing arm 2 is provided at the swing arm connecting hole and is connected to the swing arm connecting hole through a pin shaft, the swing arm 2 can rotate relative to the pin shaft, a connecting plate is fixedly provided at the upper end of the swing arm 2, an elastic supporting mechanism insertion hole is provided on the connecting plate, the elastic supporting mechanism 3 passes through the elastic supporting mechanism insertion hole and is connected to the mounting arm 1, the telescopic action of the elastic supporting mechanism 3 can drive the mounting arm 1 to rotate through the connecting plate, thereby adjusting the angle between the mounting arm 1 and the swing arm 2, and then adjusting the degree of coordination between the scraper mechanism and the soil crushing roller device.

[0027] Please refer to 1- Figure 4 The scraper mechanism includes a scraper seat 4, a scraper 5 and a scraper fastener 6. The scraper seat 4 is arranged at the end of the swing arm 2 and is connected to the swing arm 2. A fastening space is arranged inside the scraper seat 4. The scraper fastener 6 is arranged in the fastening space and is connected to the scraper seat 4. A fastening gap is reserved between the scraper fastener and the scraper seat 4 in the fastening space. The scraper 5 is arranged on the scraper fastener, and the scraper 5 is also located in the fastening gap. The scraper seat 4 cooperates with the scraper fastener 6 to fix the scraper. One end of the scraper extends out of the fastening space, and this end is the mud scraping end of the scraper.

[0028] When the scraper is installed on the soil crushing and suppressing roller device, the mounting arm 1 is connected to the soil crushing and suppressing roller device, and the elastic supporting mechanism 3 pushes one end of the swing arm 2 away from the mounting arm 1, so that the scraper at the other end of the swing arm 2 is closer to the soil crushing and suppressing roller, thereby achieving a better scraping effect. In addition, since the elastic supporting mechanism 3 is elastic, the swing arm 2 can still swing, and the scraper can move away from the soil crushing and suppressing roller when it contacts the high-hardness soil that cannot be scraped off at one time, and drive the swing arm 2 to swing. Under the action of the elastic supporting mechanism 3, the scraper scrapes off the soil by contacting the soil multiple times.

[0029] In order to stably install the scraper 5 and prevent it from falling off, a clamping tooth is provided on the top surface of the scraper fastener 6, and a plurality of clamping holes are provided on the scraper 5. When the scraper 5 is installed on the scraper fastener 6, the clamping tooth passes through a clamping hole to prevent the scraper from being offset relative to the top surface of the scraper mounting part, thereby ensuring that the scraper mechanism can be used stably. The clamping tooth on the scraper fastener 6 cooperates with the clamping hole on the scraper, and it is also convenient to adjust the position of the scraper relative to the scraper fastener 6. When the scraping end of the scraper is worn, the scraper can be moved outside the fastening space, and then the clamping tooth is matched with the corresponding clamping hole to fix the scraper.

[0030] In order to prevent the scraper fastener 6 from being displaced during use and affecting the scraping effect, the fastening space is wedge-shaped, and the cross-sectional size of the fastening space gradually decreases from the opening to the inside. The scraper fastener 6 is also a wedge-shaped structure. From the head end to the tail end of the scraper fastener 6, the cross-sectional size of the scraper fastener 6 gradually decreases. The tail end of the scraper fastener 6 extends into the fastening space, and the scraper is set on the scraper fastener 6. The more the scraper fastener 6 moves into the fastening space, the more the scraper fastener 6 can cooperate with the scraper seat 4 to fix the scraper.

[0031] The scraper fastener 6 is connected to the scraper seat 4 by bolts to prevent the hanging plate fastener from being separated from the scraper seat 4. In a further embodiment, a through hole is provided on the scraper seat 4, and a bolt passes through the through hole and is connected to the scraper fastener 6. A rotating hand wheel 7 is provided on the bolt, and the bolt can be quickly rotated by rotating the hand wheel 7, so that the scraper fastener 6 is connected to the scraper seat 4 or the scraper fastener 6 is removed from the scraper seat 4.

[0032] When in use, the scraping end of the scraper corresponds to the head end of the scraper fastener 6, and the scraping end of the scraper extends from the opening end of the fastening space. When the scraping end of the scraper contacts high-hardness soil that cannot be scraped off in one go, the soil resists the scraper and drives the scraper and the scraper fastener 6 to move into the fastening space, thereby allowing the scraper to be installed more securely.

[0033] See also Figure 1-Figure 4 The scraper seat 4 includes a seat plate, and the opposite ends of the seat plate are bent downward to make the seat plate a U-shaped plate. A fastening screw is arranged in the scraper seat 4, and the fastening screw is detachably connected to the scraper seat 4. The space above each fastening bolt in the scraper seat 4 is a fastening space. From the opening end of the fastening space to the inside of the fastening space, the distance between the fastening screw and the top surface of the seat plate gradually decreases, so that the space above each fastening bolt in the scraper seat 4 is a wedge-shaped space.

[0034] An end plate is provided at one end of the base plate corresponding to the fastening space, and a through hole is opened on the end plate. A nut or a threaded hole is provided at the tail end of the scraper fastener 6. The bolt passes through the through hole on the end plate and is threadedly connected to the scraper fastener 6, thereby connecting the scraper fastener 6 to the scraper seat 4.

[0035] See also Figure 1-Figure 4 The elastic support mechanism is a spring, and the two ends of the spring are respectively connected to the mounting arm 1 and the connecting piece. The spring is in a compressed state and has a tendency to stretch, so that the scraper can fit the soil crushing roller more closely when the mud scraper device is in use.

[0036] In order to ensure the stability of the spring installation and to limit the degree of rotation of the swing arm 2, the connecting piece is provided with a through hole, in which a connecting screw is passed, and the part of the connecting screw located on one side of the connecting piece is connected to the mounting arm 1, and rotating the connecting screw can drive the connecting screw to move axially relative to the mounting arm 1, and an adjusting hand wheel 8 is provided on the rod body of the connecting screw located on the other side of the connecting piece, and the adjusting hand wheel 8 can facilitate the rotation of the connecting screw, and the adjusting hand wheel 8 cannot pass through the through hole, which plays a role of limiting. By adjusting the connecting screw axially by adjusting the hand wheel 8, the rod length of the adjusting screw between the connecting piece and the mounting arm 1 can be adjusted, thereby limiting the swing range of the swing arm 2.

[0037] The spring sleeve is arranged outside the connecting screw rod to prevent it from being separated.
