Description

Technical Field

[0001] The utility model relates to the technical field of mortar pumps, in particular to an anti-clogging mortar pump. Background Art

[0002] A mortar pump, also known as a concrete mortar pump or a fine stone mortar pump, belongs to the category of engineering machinery. It is an automated equipment specially used to transport cement fine stone mortar and cement concrete. It usually uses oil pressure as power and can transport mortar to dozens of high-rise buildings. This equipment can greatly reduce the labor intensity of construction workers and improve construction efficiency. It is an essential equipment in the fields of construction and floor heating.

[0003] A Chinese patent with publication number CN218407928U discloses an anti-clogging horizontal mortar pump, including a mortar pump, wherein two lifting mechanisms are fixedly installed at the bottom end of the mortar pump, and the two lifting mechanisms include lifting cylinders. The two lifting cylinders are fixedly installed at the lower bottom of the mortar pump, and the output ends of the two lifting cylinders are connected to the lifting shafts. The bottom ends of the two lifting shafts are fixedly installed with mounting seats, and the bottom ends of the two mounting seats are embedded with rolling mounting balls. The outer spherical surfaces of the two balls are fixedly connected with support rods, and the bottom ends of the two support rods are fixedly installed with extrusion plates, which are in contact with the ground through the two extrusion plates, thereby obtaining greater sliding friction and improving the placement stability of the mortar pump. When the mortar pump needs to be temporarily stopped, the lifting cylinder can also be started to drive the lifting shaft to reciprocate and lift, thereby driving the extrusion plate to reciprocate and squeeze contact with the ground, thereby making it difficult for the mortar retained in the mortar pump to solidify, thereby avoiding the problem of mortar blockage when the mortar pump is stopped for a short time.

[0004] As mentioned above, the patent provides an anti-clogging horizontal mortar pump, which can use a lifting cylinder to perform reciprocating lifting when the mortar pump is out of use for a short period of time to prevent the internal mortar from solidifying easily. However, this method has a limited scope of application. If the mortar is lifted and lowered while being transported, the mortar inside the mortar pump will cause greater shaking, resulting in uneven distribution of the internal mortar, thereby affecting the efficiency of transporting the mortar. Without lifting and lowering, the mortar pump cannot achieve the anti-clogging effect when transporting mortar. Therefore, there is still room for improvement in its efficiency.

[0007] Preferably: the feeding mechanism includes a fixed block; the bottom of the fixed block is fixedly connected to the bottom of the inner wall of the splint-type shell; one side of the fixed block is fixedly connected to a hydraulic rod; the end of the hydraulic rod away from the fixed block is fixedly connected to a feed bin; a cylindrical hole matching the hydraulic rod is provided at the bottom of the feed bin; an output baffle is hingedly connected to the surface of the splint-type shell away from the motor; both sides of the output baffle are fixedly connected to a rotating rod; the end of the rotating rod away from the output baffle is rotatably connected to the inner wall of the splint-type shell; a torsion spring is sleeved on the surface of the rotating rod; the two ends of the torsion spring are respectively fixedly connected to the surface of the output baffle and the inner wall of the splint-type shell.

[0008] Preferably: the bottom of the splint-type housing is fixedly connected to one side of the top of the support base; the output shaft of the motor is fixedly connected to the transmission shaft via a coupling; the end of the transmission shaft away from the motor is rotatably connected to the surface of the splint-type housing facing the motor.

[0009] Preferably: the surface of the transmission shaft is rotatably connected with a shaft protection cover and a bearing box respectively located between the motor and the clamping plate housing; the bearing box is arranged between the surfaces of the two driven pulleys, and the belt between the two driven pulleys passes through the bearing box.

[0010] Preferably: the top of the clamping plate type housing is connected to a feed port; the side of the clamping plate type housing away from the motor and located on the top of the output baffle is connected to a discharge port.

[0011] The beneficial effects of adopting the above technical solution are:

[0012] 1. The built-in motor can drive the active pulley to start rotating. After the active pulley rotates, it cooperates with the belt to drive the two driven pulleys to start rotating. The rotating shaft is fixedly connected to the driven pulley, so that the rotating shaft can rotate with the rotation of the driven pulley, thereby driving the three-leaf vibration cam to start rotating. The three-leaf vibration cam will continuously slap the elastic vibration plate when rotating. As for the elastic vibration plate, its main function is to guide the mortar inside. After the mortar enters the splint type shell, most of it falls into the inner cavity of the splint type shell and is discharged, and the remaining small part slides into the inner cavity of the splint type shell again along the elastic vibration plate. After being slapped by the three-leaf vibration cam, the elastic vibration plate can bounce off the mortar attached to its surface, so that it can completely enter the inner cavity of the splint type shell and be discharged, thereby realizing that the mortar pump can avoid blockage during operation.

Then, the hydraulic rod works to drive the feeding bin to move so that one end of it is against the output baffle. With continuous movement, the output baffle is opened at different angles until the feeding bin is completely removed from the output baffle. Then, the mortar inside the feeding bin is cleaned to avoid large mortar accumulation inside, further ensuring the anti-blocking effect. Finally, the cleaned feeding bin is sent back into the splint-type Inside the shell, the hydraulic rod contracts at this time, and after the feed bin is completely sent into the interior of the splint-type shell, torsion springs are arranged on both sides of the output baffle door through the rotating rod. The torsion springs have a large torsion force, and the restoring force of their deformation drives the output baffle door to close, thereby making the interior of the splint-type shell airtight again, and the feed bin and the output baffle door are arranged at the same height, so that when feeding, even if the mortar is piled up high in the feed bin, the output baffle door will not be pushed open, thereby ensuring the internal airtightness of the mortar pump when it is carrying mortar, so that it can clean the mortar accumulated inside while ensuring that the mortar pump can carry out the mortar transportation work normally.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1 - Figure 5As shown, in the present embodiment, a blockage-resistant mortar pump comprises a support base 1, a splint-type shell 2, a vibration mechanism and a feeding mechanism, wherein the splint-type shell 2 is arranged on the top of the support base 1; a motor 3 is fixedly connected to the side of the top of the support base 1 away from the splint-type shell 2 through a motor seat; the vibration mechanism and the feeding mechanism are both arranged inside the splint-type shell 2; the vibration mechanism comprises an elastic vibration plate 4; a support shaft 5 is fixedly connected to the inside of the elastic vibration plate 4; both ends of the support shaft 5 are fixedly connected to the inner wall of the splint-type shell 2; the number of the elastic vibration plates 4 is set to two, and the two elastic vibration plates 4 are obliquely arranged on the inner wall of the splint-type shell 2 through two support shafts 5; the inner wall of the splint-type shell 2 and located at the two elastic vibration plates 4 The bottom is rotatably connected with a rotating shaft 6; a three-leaf vibration cam 7 is fixedly connected to the surface of the rotating shaft 6; the vibration mechanism also includes a built-in motor 8; the built-in motor 8 is fixed to the bottom of one side of the inner wall of the splint-type shell 2 through a motor tube; the output shaft of the built-in motor 8 passes through the splint-type shell 2 and extends to the outside of the splint-type shell 2; the output shaft of the built-in motor 8 is located on the outside of the splint-type shell 2 and is fixedly connected to a driving pulley 9 through a coupling; the number of the rotating shafts 6 is set to two, and one end of the two output shafts passes through the splint-type shell 2 and extends to the outside of the splint-type shell 2; the two output shafts are located on the outside of the splint-type shell 2. One end is fixedly connected to a driven pulley 10; the surface of the driving pulley 9 is connected to the surface of the driven pulley 10 through a belt transmission.

[0024] Through the above technical scheme, when working, the mortar pump is mainly transported by the splint type housing 2, and the motor 3 provides the power source. The mortar will fall into the splint type housing 2 from the top of the splint type housing 2. The splint type housing 2 is composed of two jackets and a housing, which ensures the stable working effect of the splint type housing 2. The mortar inside the splint type housing 2 can be transported out from the side away from the motor 3. When the mortar is transported to achieve the anti-blocking function, the built-in motor 8 needs to work to drive the active pulley 9 to start rotating. After the active pulley 9 rotates, the belt can drive the two driven pulleys 10 to start rotating. The rotating shaft 6 is fixedly connected to the driven pulley 10, so that the rotating shaft 6 can rotate with the rotation of the driven pulley 10, thereby driving the three-leaf vibration cam 7 to start rotating. The three-leaf vibration cam 7 When rotating, it will continuously hit the elastic vibration plate 4, and the elastic vibration plate 4 is mainly used to guide the mortar inside. Two elastic vibration plates 4 are arranged, and a support shaft 5 is fixed inside the elastic vibration plate 4. The support shaft 5 is used to fix the elastic vibration plate 4 on both sides of the inside of the splint type shell 2, and the support shaft 5 is arranged to be inclined on the inner wall of the splint type shell 2 to facilitate the guiding of the mortar. After the mortar enters the splint type shell 2, most of the mortar falls into the inner cavity of the splint type shell 2 and is discharged, and the remaining small part slides into the inner cavity of the splint type shell 2 again along the elastic vibration plate 4. After being hit by the three-leaf vibration cam 7, the elastic vibration plate 4 can bounce off the mortar attached to its surface, so that the mortar can completely enter the inner cavity of the splint type shell 2 and be discharged, thereby realizing that the mortar pump can avoid blockage during operation.

[0025] like Figure 3 - Figure 5 As shown, the feeding mechanism includes a fixed stopper 11; the bottom of the fixed stopper 11 is fixedly connected to the bottom of the inner wall of the clamping shell 2; one side of the fixed stopper 11 is fixedly connected to a hydraulic rod 12; the end of the hydraulic rod 12 away from the fixed stopper 11 is fixedly connected to a feed bin 13; a cylindrical hole 14 adapted to the hydraulic rod 12 is provided at the bottom of the feed bin 13; an output baffle 15 is hingedly connected to the surface of the clamping shell 2 away from the motor 3; both sides of the output baffle 15 are fixedly connected to a rotating rod 16; the end of the rotating rod 16 away from the output baffle 15 is rotatably connected to the inner wall of the clamping shell 2; a torsion spring 17 is sleeved on the surface of the rotating rod 16; the two ends of the torsion spring 17 are respectively fixedly connected to the surface of the output baffle 15 and the inner wall of the clamping shell 2.

[0026] Through the above technical scheme, a feeding mechanism is arranged at the bottom of the inner wall of the splint type shell 2, which is mainly composed of a fixed block 11, a feeding bin 13, a hydraulic rod 12 and an output baffle 15. The fixed block 11 is fixed to the bottom of the inner wall of the splint type shell 2 to support the hydraulic rod 12, and a cylindrical hole 14 is provided at the bottom of the feeding bin 13 to facilitate the storage of the hydraulic rod 12. The feeding bin 13 can be provided to collect the ejected mortar when the mortar pump is in a non-working state, and can also collect the mortar that has not been discharged from the inner cavity of the splint type shell 2. Then, the hydraulic rod 12 works to drive the feeding bin 13 to move so that one end of the feeding bin 13 is against the output baffle 15. With continuous movement, the output baffle 15 is opened at different angles until the feeding bin 13 is completely removed from the output baffle 15, and then the mortar inside the feeding bin 13 is discharged. Cleaning can avoid large mortar accumulation inside, further ensuring the anti-blocking effect, and finally the cleaned feed bin 13 is sent into the interior of the splint type housing 2 again. At this time, the hydraulic rod 12 contracts, and after the feed bin 13 is completely sent into the interior of the splint type housing 2, since torsion springs 17 are set on both sides of the output baffle door 15 through the rotating rod 16, the torsion spring 17 has a large torsion force, and the restoring force of its restoring deformation drives the output baffle door 15 to close, so that the interior of the splint type housing 2 is sealed again, and the feed bin 13 and the output baffle door 15 are set at the same height. In this way, when feeding, even if the mortar is accumulated high in the feed bin 13, the output baffle door 15 will not be pushed open, thereby ensuring the internal airtightness of the mortar pump when performing mortar transportation work, so that it can clean the mortar accumulated inside while ensuring that the mortar pump can perform mortar transportation work normally.

[0027] like Figure 1 and Figure 2 As shown, the bottom of the splint type housing 2 is fixedly connected to one side of the top of the supporting base 1; the output shaft of the motor 3 is fixedly connected to the transmission shaft 18 through a coupling; the end of the transmission shaft 18 away from the motor 3 is rotatably connected to the surface of the splint type housing 2 facing the motor 3; the surface of the transmission shaft 18 and located between the motor 3 and the splint type housing 2 are rotatably connected with a shaft protection cover 19 and a bearing box 20; the bearing box 20 is arranged between the surfaces of the two driven pulleys 10, and the belt between the two driven pulleys 10 passes through the bearing box 20; the top of the splint type housing 2 is connected to a feed port 21; the side of the splint type housing 2 away from the motor 3 and located at the top of the output baffle 15 is connected to a discharge port 22.

[0028] Through the above technical scheme, the motor 3 and the splint-type housing 2 are respectively arranged on both sides of the top of the support base 1. When the motor 3 is working, its output shaft drives the transmission shaft 18 to start rotating through the coupling. After the transmission shaft 18 rotates, the power is transmitted to the splint-type housing 2, so that it can carry out mortar conveying work. The shaft protection cover 19 and the bearing box 20 protect the output shaft and also protect some internal transmission parts. At the same time, openings are opened on both sides of the bearing box 20 to facilitate the transmission of the belt between the two driven pulleys 10. As for the splint-type housing 2, a feed port 21 is opened on the top for feeding mortar, and a discharge port 22 is opened on the side away from the motor 3 for discharging the internal mortar, which in turn constitutes a complete mortar conveying work.

[0029] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; technologies not described in detail in the present invention are implemented with existing technologies.
