Description

Technical Field

[0002] Construction materials such as cement and gypsum powder need to be transported from the manufacturer to the mixing station or construction site for pulping or mixing. Most existing construction sites generally use bagging or cement tank trucks to transport construction powder or granular materials. The cost of bagging transportation is high and it is not suitable for construction sites with large demand. The height of the cement tank truck is high, and the cost of using the tank truck is also high. After being transported to the destination, it needs to be unloaded quickly, which is not suitable for long-term stay at the construction site. The unloaded bulk materials need to be stored at the construction site. The existing storage method is to use a vertical closed tank to store the materials in the tank truck into the closed tank and take them as needed. The existing closed tank generally has a discharge port at the bottom of the tank. When the material is needed, the discharge port can be opened to take out the material for transportation. Since the storage tank is fixed in position and cannot be moved with the progress of construction, it is necessary to carry out secondary material transportation. The secondary transportation generally uses a manual cart to transfer, and the labor cost is high. With the enhancement of people's environmental awareness, vertical storage tanks occupy a high space and are not beautiful enough. In addition, unloading operations in an open environment can easily cause dust to spread and pollute the atmospheric environment.

Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0029] According to an embodiment of the present invention, Figures 1 to 5 As shown, the present invention provides a horizontal intelligent material storage tank, which includes a tank body 1 and a discharge device. Figure 3 The direction of the arrow indicates the flow direction of the material. Figure 4 The direction of the arrow in refractory sprocket 12 indicates the moving direction of the double-row transmission sprocket 12 on the drive shaft 7.

[0030] A vent pipe 2 and a feed pipe 3 are arranged on the tank wall of the tank body 1. The feed pipe 3 communicates with the inside and outside of the material storage tank. A plurality of sequentially arranged collecting troughs 4 are arranged at the bottom of the tank body 1.

[0031] The unloading device includes a first auger conveyor 5, a clutch mechanism and a second auger conveyor 6. A first screw shaft is arranged in the first auger conveyor 5, and the first screw shaft is arranged in the aggregate trough 4. The discharge ports of the first auger conveyors 5 in the multiple aggregate troughs 4 all extend out of the tank body 1 and are respectively connected with the pipe wall of the second auger conveyor 6; the driving shaft 7 end of the first auger conveyor 5 extends out of the tank body 1, and the driving shafts 7 of the multiple first auger conveyors 5 are arranged in parallel, and a transmission wheel is installed on the driving shaft 7 of the first auger conveyor 5; the transmission wheels on the driving shafts 7 of two adjacent first auger conveyors 5 are sequentially connected through gear transmission, chain transmission or belt transmission; a first driving motor is arranged on the outer wall of the tank body 1, and the first driving motor is connected to one of the driving shafts 7. The clutch mechanism drives the transmission wheel to slide on the driving shaft 7 to realize the linkage and separation of the transmission wheel and the driving shaft 7. A second spiral shaft is arranged in the second auger conveyor 6, a second driving motor is arranged at one end of the second auger conveyor 6, the second driving motor is connected to the second spiral shaft, and the other end of the second auger conveyor 6 is a discharge port.

[0032] When in use, the material enters the tank body 1 through the feed pipe 3 of the horizontal intelligent material storage tank. When feeding, the air pressure balance inside and outside the tank body 1 is maintained through the ventilation pipe 2. When the storage in the tank body 1 is completed and it is necessary to unload, the first drive motor and the second drive motor are turned on, and the first auger conveyor 5 is operated to send the material in each collecting trough 4 out of the tank body 1, and then the second auger conveyor 6 is relayed to the discharge port to complete the discharge. When the discharge speed requirement is not so high, the position of the transmission wheel can be adjusted through the clutch mechanism so that the transmission wheel on part of the drive shaft 7 is linked with it (that is, the transmission wheel drives the drive shaft 7 to rotate), so that part of the first auger conveyor 5 is operated, thereby achieving the purpose of controlling the discharge speed. The use of the clutch mechanism can make multiple first auger conveyors 5 share the same first drive motor, saving the number of first drive motors, reducing the cost of the entire material storage tank, and simplifying the structure.

[0033] Furthermore, if Figure 4As shown, the driving shaft 7 of the first auger conveyor 5 is a cylindrical structure, and a tooth groove area 8 and an idle area 9 are provided on the driving shaft 7. The tooth groove area 8 is circumferentially provided with protruding key teeth 10, and the central hole wall of the transmission wheel is provided with a groove corresponding to the key teeth 10 in the tooth groove area 8. The inner diameter of the central hole of the transmission wheel corresponds to the outer diameter of the idle area 9 of the driving shaft 7. When in use, when the first auger conveyor 5 is required to operate, the clutch mechanism is operated to move the transmission wheel to the tooth groove area 8, so that the key teeth 10 in the tooth groove area 8 match with the grooves on the central hole wall of the transmission wheel, so that the transmission wheel drives the driving shaft 7 to rotate synchronously. When the first auger conveyor 5 is not required to operate, the clutch mechanism is operated to move the transmission wheel to the idle area 9, so that the transmission wheel idles relative to the driving shaft 7.

[0034] Furthermore, the clutch mechanism includes a shift lever and a shift plate 11, the shift plate 11 includes a shift inner ring and a shift outer ring, the shift outer ring is sleeved on the outer surface of the shift inner ring, and rotates freely relative to the shift inner ring, the shift inner ring is sleeved on the drive shaft 7, and is coaxially connected to the transmission wheel, and one end of the shift lever is connected to the shift outer ring; the outer wall of the tank body 1 is provided with an articulated support rod, and the middle part of the shift lever is articulated with the free end of the articulated support rod. When in use, by moving the shift lever, the transmission wheel is moved in the tooth groove area 8 and the idle area 9 of the drive shaft 7, thereby realizing the switching of the corresponding first auger conveyor 5 between operation and stop.

[0035] Furthermore, the transmission wheel is a double-row transmission sprocket 12, and the double-row transmission sprockets 12 on two adjacent drive shafts 7 are sequentially connected by a transmission chain 13. In this embodiment, since the double-row transmission sprocket 12 can reciprocate on the drive shaft 7, in order to avoid the position mismatch of the double-row transmission sprockets 22 on the adjacent drive shafts 7, the width of the transmission chain 13 is more than 1.5 times the width of the double-row transmission sprocket 22. When in use, since the width of the transmission chain 13 is greater than the width of the double-row transmission sprocket 22, the stability of the chain drive will not be affected when the double-row transmission sprocket 22 is shifted.

[0036] Furthermore, a reducer 14 is provided between the first drive motor and the drive shaft 7, and the first drive motor drives the drive shaft 7 to rotate through the reducer 14; the reducer 14 is a dual-speed ratio reducer 14. When in use, the reduction ratio of the reducer 14 can be adjusted according to demand, thereby adjusting the unloading speed.

[0037] Furthermore, the conveying pipe of the second auger conveyor 6 is divided into two sections, and the two sections of the conveying pipe are connected by a T-shaped three-way flange pipe 16. The spiral blades on the second spiral shaft in the conveying pipes at both ends of the T-shaped three-way flange pipe 16 rotate in opposite directions. The other end of the second auger conveyor 6 is closed, and the third port of the T-shaped three-way flange pipe 16 is the discharge port. When in use, the materials in the conveying pipes at both ends of the T-shaped three-way flange pipe 16 are spirally conveyed by the spiral blades and discharged through the third port. Preferably, the T-shaped three-way flange pipe 16 is a rotatable three-way flange pipe, which can be rotated as needed when in use, so as to achieve flexible adjustment of the discharge port position.

[0038] Furthermore, it also includes a third auger conveyor 15, the feed end of the third auger conveyor 15 is connected to the third port of the T-type three-way flange pipe 16, and the discharge end of the third auger conveyor 15 is a discharge port. Since the third auger conveyor 15 is connected to the third port of the T-type three-way flange, the installation angle can be adjusted during use to make the conveying pipe of the third auger conveyor 15 rotate around the pipe axis where the third port of the T-type three-way flange is located, and at the same time, the T-type three-way flange can rotate around the conveying pipe axis of the second auger conveyor 6, so as to realize the third auger conveyor 15 to stay at any position within the spherical range, expand the setting position of the discharge port, and facilitate the stop and unloading at any position.

[0039] Furthermore, the aggregate trough 4 is a V-shaped trough, the upper edges of two adjacent aggregate troughs 4 are connected, and the angle between the trough wall of the aggregate trough 4 and the horizontal plane is greater than the repose angle of the material in the tank. By limiting the angle between the trough wall of the aggregate trough 4 and the horizontal plane, it is avoided that part of the material stays on the inner wall of the aggregate trough 4 in the later stage of unloading and cannot fall and unload, and complete unloading is achieved.

[0040] Furthermore, the bottom of the collecting trough 4 is an arc groove, and the first spiral shaft is arranged in the arc groove; the arc groove is arranged to match the first spiral shaft, which can ensure that the first spiral shaft plays a maximum pushing role. Preferably, the arc of the arc groove is Thereby, most of the arc grooves are wrapped around the first spiral shaft, achieving a balance between feeding and discharging, and making the discharging efficiency of the first auger conveyor 5 the highest.

[0041] Furthermore, the horizontal intelligent material storage tank also includes a chassis, which is arranged at the lower part of the tank body 1 and supports the tank body 1. A downward support seat is arranged on the frame of the chassis, and the height of the support seat is adjustable; in this embodiment, the support seat includes a hydraulic lifting rod and a threaded lifting rod, which are arranged in parallel and respectively placed at the four corners of the chassis; preferably, a traction rod is arranged at one end of the chassis, and wheels are arranged on both sides of the chassis. When the material storage tank arrives at the storage area, the hydraulic mechanism is operated to extend the hydraulic lifting rod, lift the entire material storage tank, and lift the wheels off the ground, and then adjust the threaded lifting rod to extend it to the bottom end touching the ground, and finally retract the hydraulic lifting rod, so as to achieve the placement of the entire material storage tank.

[0042] In summary, the horizontal intelligent material storage tank provided by the present invention adopts multiple groups of parallel first auger conveyors arranged in the corresponding aggregate trough, which realizes the rapid unloading of materials in the material storage tank, and by setting the linkage between the driving shafts of multiple first auger conveyors, the number of first driving motors is saved, and the equipment manufacturing cost is reduced; by setting a clutch mechanism, cooperating with the tooth groove area, idling area and the groove of the center hole of the transmission wheel on the driving shaft, the start and stop of any driving shaft is realized, and the unloading speed can be adjusted arbitrarily. The present invention avoids the material staying on the inner wall of the aggregate trough and cannot be discharged by setting the inclination angle of the trough wall of the aggregate trough, thereby realizing complete unloading; by setting the T-type three-way flange pipe and the third auger conveyor, the setting position of the discharge port is expanded, which is convenient for stopping and unloading at any position.
