Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing tanks, in particular to a vortex type mixing tank with increased stirring volume. Background Art

[0002] Most daily concrete mixing tanks have an inclination angle, with the tail higher than the front, and the angle is mostly more than 10°. The design defects of such a mixing tank angle are very obvious: 1. Due to the inclination angle, the overall height of the mixing tank is relatively high, which makes it difficult to pass through height-restricted sections, cave construction, mine construction, coal mine construction, tunnels, etc. It has poor adaptability and is difficult to transport in the above environments, and has limitations; 2. The capacity of the general mixer tank is limited, and the concrete pulled is relatively small. The concrete loaded in the inclined tank of the general mixer truck generally cannot exceed the lowest position of the tail discharge port, so it directly leads to less concrete loaded in the general concrete mixer truck, and the entire tank can only be loaded with two-thirds, and the remaining space is very wasted. 3. Because the mixer tank is relatively high and the entire tank is not filled, the vehicle is unstable during driving, the concrete shakes at any time, the stability is poor, and it is easy to roll over when passing through gully sections.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0027] See also Figure 1 The utility model provides a technical solution, a vortex mixing tank for increasing stirring volume, wherein a base frame 1 is fixed on the top surface of the rear part of a mixing tank transport vehicle, and a front bracket 11 and a rear bracket 12 are fixed to the front and rear ends of the base frame 1 respectively.

[0028] A reducer 3 is fixed on the top of the front bracket 11, and the reducer 3 is drivingly connected to the driving motor.

[0029] The tank body 2 includes a horizontally arranged cylindrical barrel 21 and a conical barrel 22 connected to the rear end of the cylindrical barrel 21. A shaft connected to the power output shaft of the reducer 3 is fixed at the center of the front end face of the cylindrical barrel 21, and multiple groups of front spiral blades 211 are fixed to the inner circumferential wall of the cylindrical barrel 21; a conical guide barrel 222 is provided at the front of the center of the inner cavity of the conical barrel 22, and a front baffle 223 and a rear baffle 224 are respectively fixed between the front and rear ends of the conical guide barrel 222 and the inner circumferential wall of the conical barrel 22, and a tail spiral blade 225 is fixed on the inner circumferential wall of the rear part of the conical guide barrel 222. Among them, the driving motor drives the tank body 2 to rotate as a whole through the reducer 3. In order to improve the overall operation stability of the tank body 2, a support member 6 is also provided. The support member 6 includes a wheel seat 61 fixed on the top surface of the base frame 1 near the rear end and a supporting wheel 62 rotatably installed in the wheel seat 61. An annular guide rail 221 is fixedly mounted on the outer peripheral wall of the conical cylinder 22 corresponding to the position of the supporting wheel 62, and the two sides of the bottom of the annular guide rail 221 are rotatably supported on the corresponding supporting wheels 62 respectively.

[0030] A rear support 13 is fixed to the top of the rear bracket 12, and diagonal brackets 14 are fixed to both sides of the top surface of the rear support 13, the top of the discharge hopper 5 is fixed to the inner cavity of the rear support 13, and the top of the diagonal bracket 14 is fixed to the two side walls of the feed hopper 4. A cylinder extending forward is fixed to the front wall of the bottom of the feed hopper 5.

[0031] The rear end of the conical cylinder 22 is fixed with an annular plugging plate 226 that is rotatably sleeved and matched with the cylinder on the front wall of the bottom of the feed hopper 4. The bottom of the annular plugging plate 226 is provided with a fan-shaped opening 227. The rotating baffle 7 includes an annular groove 71 that is rotatably mounted on the outer edge of the annular plugging plate 226, and an annular baffle 72 that is arranged at the inner edge of the rear part of the annular groove 71 and whose front wall is in contact with the rear wall of the annular plugging plate 226. The annular baffle 72 is provided with a fan-shaped groove 721 at a position corresponding to the fan-shaped opening 227. That is, when feeding into the tank body 2 through the feed hopper 4, the fan-shaped groove 721 is staggered with the fan-shaped opening 227, so that the concrete entering the rear end of the conical cylinder 22 enters the cylindrical cylinder 21 through the conical guide cylinder 222 under the pushing action of the tail spiral blade 225.

[0032] When discharging is required, the rotating baffle 7 is rotated as a whole so that the fan-shaped groove 721 is opposite to the fan-shaped opening 227. At this time, the front spiral blade 211 pushes the concrete backward as the cylindrical barrel 21 rotates, so that the concrete is transferred from the conical guide barrel 222 to the rear part of the conical barrel 22; under the pushing action of the tail spiral blade 225, the concrete passes through the fan-shaped opening 227 and the fan-shaped groove 721 in turn and falls into the discharging hopper 5 to complete the discharging process.

[0033] In order to improve the smoothness of the rotation of the rotating baffle 7, a slewing bearing can be provided between the annular groove 71 and the outer edge of the annular blocking plate 226. A sealing member, such as a rubber sealing ring, is provided between the bottom cylinder of the feed hopper 4 and the inner edge of the annular blocking plate 226 and the inner edge of the annular baffle 72.

[0034] A positioning hole 1 228 and a positioning hole 229 are provided near the outer edge of the annular blocking plate 226. The angle formed by the positioning hole 1 228, the positioning hole 229 and the center of the annular blocking plate 226 is not less than the center angle corresponding to the fan-shaped opening 227. The front wall of the annular groove 71 is fixedly mounted with a threaded sleeve 73, and the inner thread of the threaded sleeve 73 is mounted with a positioning screw 74. The rear end of the positioning screw 74 is sleeved and matched with the positioning hole 1 228 and the positioning hole 229. That is, when the rotating baffle 7 is rotated so that the positioning screw 74 corresponds to the positioning hole 228, the positioning screw 74 is screwed so that the rear end of the positioning screw 74 is inserted into the positioning hole 228. At this time, the fan-shaped groove 721 is aligned with the fan-shaped opening 227 to facilitate discharge; when the rotating baffle 7 is rotated so that the positioning screw 74 corresponds to the positioning hole 229, the positioning screw 74 is screwed so that the rear end of the positioning screw 74 is inserted into the positioning hole 229. At this time, the fan-shaped groove 721 is staggered with the fan-shaped opening 227 to facilitate feeding.

[0035] In order to facilitate cleaning or maintenance of the inner cavity of the tank body 2, an inspection hole 212 is opened on the wall of the cylindrical tube 21, and a detachable sealing plate 213 is covered outside the inspection hole 212. The sealing plate 213 is fixed to the inspection hole 212 with bolts.
