The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] Reference Figures 1 to 8 As shown, the present invention provides a pulp throwing device, comprising: a supporting frame 1, a pulp holding roller 2, a roller 3, an elastic rod 4 and a material spoon assembly 5.

[0044] The slurry drum 2 is used to contain mortar. The slurry drum 2 is rotatably mounted on the support frame 1. The support frame 1 is equipped with a locking member 21. The locking member 21 is used to lock the slurry drum 2. The side wall of the slurry drum 2 is provided with an opening 20.

[0045] The roller 3 is rotatably mounted in the pulp drum 2. The roller 3 and the pulp drum 2 are coaxially arranged.

[0046] The number of the elastic rods 4 is multiple. The elastic rods 4 are detachably mounted on the roller 3. The multiple elastic rods 4 are arranged at equal intervals along the circumferential direction of the roller 3.

[0047] The volume of the spoon assembly 5 is adjustable. The spoon assembly 5 is installed at one end of the elastic rod 4 away from the roller 3. A stopper 22 is installed inside the opening 20 of the slurry drum 2. The stopper is arranged inside the slurry drum and is located inside the opening 20 of the slurry drum 2.

[0048] The height of the support frame 1 is adjustable. When throwing mortar, the construction worker holds the support frame 1 and rotates the roller 3. After the roller 3 is rotated, the scoop assembly 5 scoops up the mortar and presses against the blocking rod 22, and the elastic rod 4 is bent and deformed to allow the scoop assembly 5 to bypass the blocking rod 22. The scoop assembly 5 bypasses the blocking rod 22, and the mortar in the scoop assembly 5 is thrown out of the mortar drum 2 through the opening 20 under the action of inertia.

[0049] The pulp-throwing device of the present invention can be modularly installed on the roller and the pulp-containing drum, which is convenient for replacement and maintenance, thereby enhancing the practicality and durability of the pulp-throwing device of the present invention.

[0050] The slurry-throwing equipment of the present invention can flexibly adjust the volume of the scoop assembly to match the different gradings of the mortar thrown and the unevenness of the particles on the surface after the slurry is thrown. At the same time, the elastic rod is bent and deformed through the baffle rod to allow the scoop assembly to bypass the baffle rod. When the scoop assembly bypasses the baffle rod, the mortar in the scoop assembly is thrown out of the slurry drum through the opening under the action of inertia and adheres to the wall. The slurry-throwing equipment of the present invention can ensure the slurry output amount and slurry output speed, thereby improving the stability and uniformity of the slurry throwing.

[0051] See Figure and Figure 2 In this embodiment, the support frame is shaped like a Y as a whole. Specifically,

[0052] The support frame 1 includes a support rod assembly 11 and a support plate 12 .

[0053] The length of the support rod assembly 11 is adjustable. In the present invention, in view of the construction conditions of walls of different heights, a support rod assembly is added to make it more applicable and more suitable for construction operations.

[0054] In some embodiments, the support rod assembly is a telescopic rod.

[0055] In this embodiment, the support rod assembly includes two coaxially arranged vertical pipes. The two vertical pipes are connected by a connecting sleeve. Specifically, both ends of the connecting sleeve are respectively formed with internal threads. The ends of the vertical pipe are formed with external threads. The ends of the two vertical pipes are respectively threadedly connected to the two ends of the connecting sleeve.

[0056] The supporting plate 12 is fixed on the support rod assembly 11. The supporting plate 12 has vertically arranged ear plates 121 at opposite ends. The two ends of the roller 3 extend to the outside of the two ends of the pulp drum 2. The two ends of the roller 3 are rotatably mounted on the ear plates 121 at opposite ends of the supporting plate 12, and the locking member 21 is mounted on the ear plates 121.

[0057] The ear plate 121 is equipped with an electric drive device 13 for driving the roller 3 .

[0058] In other embodiments, the end of the roller extends to the outside of the pulp drum and is connected with a handle. During the construction process, the construction personnel drive the roller to rotate by turning the handle.

[0059] In this embodiment, an electric drive device is installed on one ear plate, and the electric drive device is an electrode. The output shaft of the motor is coaxially connected to one end of the roller. The other end of the roller is connected to a handle.

[0060] The ear plate 121 is provided with a first locking hole. The end surface of the pulp holding cylinder 2 is provided with a plurality of second locking holes. The second locking holes are blind holes. The plurality of second locking holes are arranged at intervals along the circumferential direction of the roller 3. The locking member 21 is detachably inserted into the first locking hole and a second locking hole.

[0061] In this embodiment, the locking member is a plug rod.

[0062] See also Figure 4 and Figure 5 As shown, each elastic rod 4 includes a plurality of elastic rods 4. The plurality of elastic rods 4 are arranged along the axial direction of the roller 3.

[0063] In this embodiment, the roller is cylindrical, and five elastic rods are installed on the circumference of the roller, and the five elastic rods are arranged at equal intervals.

[0064] In this embodiment, the opening 20 of the stock drum 2 is arranged along the axial direction of the stock drum 2. The length of the opening 20 of the stock drum 2 is adapted to the length of the stock drum 2.

[0065] The outside of the opening of the pulp holding drum 2 is connected with a guide cylinder.

[0066] See also Figure 6 As shown, the elastic rod 4 includes a coaxially connected elastic section 42 and a rigid section 41. The scoop assembly 5 is mounted on the rigid section 41. The elastic section 42 is connected with an anchor 43, and the anchor 43 is detachably mounted on the drum 2.

[0067] In this embodiment, the elastic section is a plastic elastic section. The rigid section is a metal rigid section. The anchor is in an inverted T shape. A through groove is provided on the circumferential surface of the roller. The cross section of the through groove is adapted to the shape and size of the anchor. The anchor is detachably embedded in the through groove of the roller.

[0068] See also Figures 6 to 8 As shown, the scoop assembly 5 includes two end plates 51 and two arc-shaped panels 52 .

[0069] In this embodiment, the two end plates 51 are arranged along the axial direction of the rigid section 41. Two guide grooves are formed on opposite sides of the two end plates 51, and the two guide grooves are arc-shaped and concentrically arranged.

[0070] Two arc panels 52 are attached to each other. The two ends of the arc panels 52 are respectively slidably arranged in the guide grooves corresponding to the positions of the two end plates 51. The two arc panels 52 and the two end plates 51 enclose a material loading space.

[0071] A driving structure for driving the two curved panels 52 to move toward or away from each other is installed on the end plate 51 .

[0072] The sizes of the two end plates 51 are different. Specifically, the size of one end plate close to the elastic section is smaller than the size of the other end plate away from the elastic section. The width of the curved panel in its arc direction gradually decreases from one end of the curved panel in its length direction to the other end.

[0073] In this embodiment, an insert plate is formed on the end surface of the curved panel 52. The thickness of the insert plate is less than the thickness of the curved panel. The insert plate is arranged in the middle of the curved panel.

[0074] As a preferred implementation, the driving structure includes: two racks 541 and a rotating shaft 53 .

[0075] The opposite sides of the plug plates of the two arc panels 52 are respectively provided with racks 541. The rotating shaft 53 is rotatably mounted on the end plate 51. The rotating shaft 53 is coaxially connected with a gear 542. The gear 542 is arranged between the two racks 541. The opposite sides of the gear 542 are respectively meshed with the two racks 541.

[0076] When the rotating shaft 53 is rotated, the gear 542 drives the two racks 541 to move toward or away from each other to move the two curved panels 52 toward or away from each other, thereby reducing the volume of the loading space when the two curved panels 52 move toward each other and increasing the volume of the loading space when the two curved panels 52 move away from each other.

[0077] As a preferred embodiment, the end plates are semicircular. Guide rods are connected between the two opposite sides of the two end plates. When the scoop assembly presses the blocking rod, the guide rod can resist the squeezing of the blocking rod on the scoop assembly, so that the mortar is firmly placed on the scoop assembly and is thrown out by inertia after the scoop assembly bypasses the blocking rod.

[0078] The present invention provides a construction method of a slurry throwing device, comprising the following steps:

[0079] S1: Rotate the pulp drum 2 so that the opening 20 of the pulp drum 2 is disposed toward the wall.

[0080] S2: The locking member 21 locks the pulp holding drum 2.

[0081] S3: Pour the mortar into the mortar drum 2.

[0082] S4: Rotate the roller 3, the scoop assembly 5 scoops up the mortar and presses against the blocking rod 22, the elastic rod 4 bends and deforms to allow the scoop assembly 5 to bypass the blocking rod 22. The scoop assembly 5 bypasses the blocking rod 22, and the mortar in the scoop assembly 5 is thrown out of the mortar drum 2 through the opening 20 under the action of inertia and adheres to the wall.

[0083] The slurry throwing device of the present invention drives the roller to rotate through a motor or a rotating handle. During this process, the blocking rod will cause the elastic rod to undergo elastic deformation under the guidance of the guide rod, thereby causing the material spoon assembly to bypass the blocking rod. After the material spoon assembly bypasses the blocking rod, the elastic deformation of the elastic rod will immediately recover to generate elastic force and cooperate with the centrifugal force of the roller to throw out the quantitative mortar in the material spoon assembly, and finally form a slurry throwing layer that evenly covers the wall surface, providing a good working surface for subsequent processes.

[0084] The volume of the material spoon assembly can be adjusted through the rotating shaft, so that the construction effects of different mortar types can be achieved quickly and efficiently.

[0085] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
