[0024] The upper surface of table body 1 is fixedly installed with discharging cover 4 by two supporting plates, the top of discharging cover 4 is fixedly installed with feeding bin 5 communicated with itself, feeding bin 5 is symmetrically rotatably installed with rotating rod 6 in, rotating rod 6 is fixedly sleeved with crushing roller 7, two ends of rotating rod 6 all pass out feeding bin 5, rotating rod 6 is fixedly sleeved with gear 8, two gear 8 are meshingly connected, one of rotating rod 6 and the output shaft of driving motor 2 are all fixedly sleeved with sprocket 9, two sprocket 9 are meshingly wound with chain 10.

[0025] When needing to convey earth material, first start driving motor 2, the output shaft of driving motor 2 will rotate with rotating shaft and conveying roller, to make conveying belt 3 operate, at this time, one of rotating rod 6 will rotate under the transmission of two sprocket 9 and chain 10, and the other rotating rod 6 will also rotate under the transmission of two gear 8, so that two crushing rollers 7 will rotate oppositely at this time, then the earth material to be conveyed is put into from the top of feeding bin 5, the earth material in feeding bin 5 is crushed by two crushing rollers 7, and then falls from discharging cover 4 to the surface of conveying belt 3, to avoid large size lump earth material from being conveyed.

[0026] The upper surface of the table body 1 is symmetrically fixedly provided with two baffles 11, which are located at the two sides of the conveying belt 3 and are rotatably sleeved on two rotating shafts.

[0027] The baffles 11 can prevent the soil on the upper surface of the conveying belt 3 from falling off from the two sides of the conveying belt 3 during the conveying process.

[0028] The side of the feeding bin 5 away from the gear 8 is provided with an impact assembly for shaking off the soil adhered to the surface of the crushing roller 7, which comprises a mounting plate fixedly installed on the side wall of the feeding bin 5, two impact balls 12 and two force receiving blocks 13, the two force receiving blocks 13 are fixedly installed on one end of the two rotating rods 6, the two sides of the mounting plate are provided with two telescopic components, the two impact balls 12 are fixedly connected with the two telescopic components, the telescopic component comprises a spring rod 15, the two ends of the spring rod 15 are fixedly connected with the impact ball 12 and the mounting plate, the surface of the force receiving block 13 is circumferentially provided with a plurality of impact openings 14 for the impact of the impact ball 12, and the longitudinal section of the impact opening 14 is a right-angled trapezoid.

[0029] When the rotating rod 6 rotates, the two force receiving blocks 13 also rotate relatively, so that the impact ball 12 intermittently enters the plurality of impact openings 14 on the surface of the force receiving block 13, when the impact ball 12 is in sliding contact with the surface of the force receiving block 13, the spring rod 15 is in a contracted state, when the force receiving block 13 rotates to the position where the impact opening 14 on the surface corresponds to the impact ball 12, the blocking effect of the surface of the force receiving block 13 on the impact ball 12 disappears, the impact ball 12 rapidly enters the impact opening 14 under the elastic potential of the spring rod 15, and collides with the wall of the impact opening 14, then, with the rotation of the force receiving block 13, the impact ball 12 is in sliding contact with the inclined wall of the impact opening 14, the spring rod 15 gradually contracts, the impact ball 12 slides out of the impact opening 14 and is in sliding contact with the surface of the force receiving block 13, when the lower force receiving block 13 rotates to the position where the next impact opening 14 corresponds to the impact ball 12, the impact ball 12 enters the impact opening 14 under the elastic potential of the spring rod 15 and collides with the wall of the impact opening 14, that is, the impact ball 12 intermittently collides with the force receiving block 13.

[0030] In the process of crushing the soil material, part of the soil material may adhere to the surface of the crushing roller 7, and when the impact ball 12 impacts the force-receiving block 13 intermittently, an impact force is generated. Since the force-receiving block 13 is fixedly connected with the rotating rod 6, and the rotating rod 6 is fixedly sleeved with the crushing roller 7, according to the force transmission principle, the impact force generated by the impact ball 12 to the force-receiving block 13 is transmitted to the crushing roller 7 through the rotating rod 6. The impact force breaks the adhesion between the soil material and the surface of the crushing roller 7. When the impact ball 12 collides with the force-receiving block 13, instantaneous vibration is generated. The vibration is transmitted to the crushing roller 7 along the rotating rod 6. The vibration causes high-frequency micro displacement of the surface of the crushing roller 7, destroys the relatively stable adhesion state formed between the soil material and the surface of the crushing roller 7, and makes the adhered soil material more easily separate from the surface of the crushing roller 7, so that the crushing work of the crushing roller 7 is not affected by too much adhered soil material.

[0031] The surfaces of the force-receiving block 13 and the impact ball 12 are coated with smooth paint, which is polytetrafluoroethylene paint. The polytetrafluoroethylene paint can reduce the friction between the contact surfaces of the force-receiving block 13 and the impact ball 12, so that the rotation of the force-receiving block 13 is smoother.

[0032] In the utility model, when it is necessary to convey the soil material, first, the driving motor 2 is started, the output shaft of the driving motor 2 drives the rotating shaft and the conveying roller to rotate, so that the conveying belt 3 operates. At this time, under the transmission of the two sprockets 9 and the chain 10, one of the rotating rods 6 rotates, and under the transmission of the two gears 8, the other rotating rod 6 also rotates, so that the two crushing rollers 7 rotate relatively. Then, the soil material to be conveyed is put into the top end of the feeding bin 5, and the soil material in the feeding bin 5 is crushed by the two crushing rollers 7 and then falls from the discharge cover 4 to the surface of the conveying belt 3, that is, the soil material is crushed before being conveyed, so that large-size clumps are avoided, and no additional power driving device is needed, so that no additional power cost is generated.

[0033] In the utility model, unless otherwise specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood in a broad sense.

[0034] The above is only a preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
