Description

Technical fields:

[0001] This utility model relates to the technical field of mortar processing equipment, and more specifically to a three-way material distribution device. Background technology:

[0002] In the processing of existing building materials, such as mortar, the mortar batches are lifted by a hoist and flow out from the two side discharge pipes through a three-way material distribution device connected to the hoist, and then enter the corresponding storage tank. Sometimes, it is necessary to ensure that the raw materials only flow out from one side of the discharge pipe. In this case, the valve plate on the three-way material distribution device needs to be rotated to close the inlet of one of the discharge pipes, so that it can flow out from the other discharge pipe.

[0003] After prolonged operation, this three-way material distribution device may experience problems such as the valve plate getting stuck due to raw materials or blockage in the dispensing pipe. In such cases, maintenance is required. The current method involves forming a maintenance through hole on the side plate of the dispensing pipe and covering it with a fixed cover plate. During maintenance, the cover plate needs to be opened. However, after opening the cover plate, it needs to be removed from the dispensing pipe. When there is no suitable place to put it, it needs to be manually supported or held, which is very troublesome and affects the efficiency of maintenance. Utility model content:

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a three-way material distribution device. Its cover plate can be flipped after opening, without separating from the corresponding material distribution pipe, and without manual support or holding, which greatly reduces maintenance troubles, facilitates maintenance, and improves maintenance efficiency.

[0021] For example, see below. Figures 1 to 4 As shown, a three-way material distribution device includes a three-way main housing 10, the top of which is formed with an upwardly extending main feed pipe 11, and the lower parts of the left and right sides of the three-way main housing 10 are formed with downwardly and outwardly extending discharge pipes 12.

[0022] The upper side plate of the discharge pipe section 12 has an inspection through hole 13 formed in the middle. A detachable cover plate 20 is installed on the top surface of the upper side plate of the discharge pipe section 12 at the inspection through hole 13. The cover plate 20 is movably installed on the discharge pipe section 12.

[0023] Furthermore, an extension sleeve 131 with a rectangular frame cross-section is welded and fixed to the top surface of the upper side plate of the feed pipe section 12 surrounding the inspection through hole 13. The extension sleeve 131 communicates with and is aligned with the corresponding inspection through hole 13.

[0024] A connecting block is fixed on the lower outer side wall of the extension sleeve 131, and a rotating connecting block 21 is welded and fixed on the lower side wall of the cover plate 20. The rotating connecting block 21 is movably connected to the connecting block through a hinge shaft. The cover plate 20 presses against the outer end face of the corresponding extension sleeve 131 and covers the middle through hole of the extension sleeve 131.

[0025] A rectangular frame-shaped sealing groove is formed in the middle of the outer end face of the extension sleeve 131. The sealing ring 3 is nested in the sealing groove, and the outer wall surface of the sealing ring 3 presses against the inner wall surface of the corresponding cover plate 20. Through the sealing effect of the sealing ring 3, the leakage of raw material powder from between the extension sleeve 131 and the cover plate 20 can be reduced.

[0026] Furthermore, a gripping part is fixed on the outer wall surface of the cover plate 20. The gripping part facilitates manual gripping to open the cover plate 20.

[0027] Furthermore, a first connecting plate 210 is welded and fixed to the upper side wall of the cover plate 20, and a second connecting plate 132 is welded and fixed to the upper outer side wall of the extension sleeve 131. The first connecting plate 210 has multiple upper through holes, and the second connecting plate 132 has multiple threaded through holes. The threaded through holes are aligned with the corresponding upper through holes. The screw part of the fixing bolt 5 is inserted into the corresponding upper through hole and screwed into the corresponding threaded through hole. The bottom surface of the rotating part of the fixing bolt 5 presses against the top surface of the corresponding first connecting plate 210.

[0028] Furthermore, a sealing sheet 6 is sandwiched between the first connecting plate 210 and the second connecting plate 132, and the threaded part of the fixing bolt 5 is inserted into the corresponding through hole formed on the sealing sheet 6.

[0029] A through-rotating shaft 14 is installed at the bottom of the middle part of the three-way main housing 10. The two ends of the rotating shaft 14 extend out of the outer side wall of the front and rear side plates of the three-way main housing 10 and are movably connected to the three-way main housing 10 through bearings installed on the outer side of the front and rear side plates of the three-way main housing 10. A valve plate 30 is fixed on the part of the rotating shaft 14 located in the three-way main housing 10. The valve plate 30 corresponds to the part of the two branch discharge pipes 12 that communicate with the bottom of the main feed pipe 11.

[0030] A connecting seat 15 is fixed on the outer wall of one of the discharge pipe sections 12. An electro-hydraulic push rod 40 is fixed on the top surface of the connecting seat 15. A swing arm 16 is fixed on one end of the rotating shaft 14 that extends out of the three-way main housing 10. The connecting block fixed at the end of the push rod of the electro-hydraulic push rod 40 is movably connected to the upper end of the swing arm 16 through a hinge shaft.

[0031] Furthermore, an inclined support plate 17 is fixed on the inner wall of the part where the bottom of each branch discharge pipe section 12 communicates with the bottom of the main feed pipe section 11. A central through groove 171 is formed in the middle of the inclined support plate 17. The valve plate 30 corresponds to both inclined support plates 17. The valve plate 30 presses against one of the inclined support plates 17 and covers the corresponding central through groove 171.

[0032] Furthermore, the bottom cross-section of the valve plate 30 is arc-shaped, and spring sealing strips 1 are fixed on its left and right sides. The bottom of the two inclined support plates 17 are close together and have an arc-shaped groove formed above them. The bottom of the valve plate 30 is in the groove and fits with the bottom surface of the groove. The inner wall of the inclined support plates 17 on the left and right sides of the groove has a discharge through hole 121 that communicates with the corresponding discharge pipe 12. The spring sealing strip 1 fits with the inner wall of the groove, and the bottom surface of one of the spring sealing strips 1 is pressed against the bottom surface of the middle part of the groove.

[0033] The function of this elastic sealing strip 1 is to move the powder in the groove through the corresponding elastic sealing strip 1 to the corresponding discharge hole 121 when the valve plate 30 is flipped. It also ensures that the valve plate 30 can rotate, reduces the accumulation of powder in the groove and prevents it from being clamped and hindering the normal rotation of the valve plate 30.

[0034] In this embodiment, the valve plate 30 is vertically positioned by pushing the push rod of the electro-hydraulic push rod 40. At this time, raw material powder or sand entering from the main feed pipe 11 can flow out from the two branch feed pipes 12. By pushing the push rod of the electro-hydraulic push rod 40, the valve plate 30 can be flipped to the left, covering the central through groove 171 of the left inclined support plate 17. At this time, the material enters from the central through groove 171 of the right inclined support plate 17 and flows out from the right branch feed pipe 12. Similarly, when the push rod of the electro-hydraulic push rod 40 retracts, the valve plate 30 flips to the right, covering the central through groove 171 of the right inclined support plate 17. At this time, the material enters from the central through groove 171 of the left inclined support plate 17 and flows out from the left branch feed pipe 12.

[0035] When maintenance is required, the fixing bolts 5 can be removed to open the corresponding cover plate 20. At this time, the cover plate 20 will not separate from the tee main housing 10, which facilitates maintenance. There is no need for manual holding or supporting of the cover plate 20, which greatly reduces the difficulty of operation and has a good effect.

[0036] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
