Description

Technical Field

[0001] The utility model relates to a powder material transportation device, which is particularly applicable to industries of bulk materials such as bulk cement, flour, grain, feed and the like. Background Art

[0002] At present, our company has developed a truck-mounted cement silo. It can already transport bulk materials in batches. In order to facilitate the control of the discharge volume, a weight sensor is also installed on the vehicle body, which requires a space on the vehicle body for the silo to float up and down.

[0003] However, during transportation, the warehouse may change its position (such as jumping up and down) or posture (such as tilting) relative to the vehicle body, posing a hidden danger to transportation safety. Utility Model Content

[0007] The blocking member on the outer surface of the bin body is a reinforcement frame, and the reinforcement frame surrounds the outside of the bin body.

[0008] A reinforcing frame is fixed on the outer surface of the waist of the bin body.

[0009] There are four weighing sensors, which are arranged at the four corners of the reinforcement frame.

[0010] The weighing sensor is a cantilever weighing sensor, which is fixed on the reinforcement frame, and a probe thereof contacts a detection plate, and the detection plate is fixed on the constraint frame.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the utility model. DETAILED DESCRIPTION

[0015] The utility model is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] like Figure 1 A safe powder material transportation device includes a vehicle body 10 and a bin body 20. The vehicle body 10 includes a constraint frame 13. The bin body 20 is located on the inner side of the constraint frame 13. The constraint frame 13 and the outer contour of the bin body 20 are matched with each other in an up and down floating manner. A blocking member is fixed on the outer surface of the bin body 20. The blocking member is located above the constraint frame 13. A weighing sensor 30 is provided between the blocking member and the constraint frame 13. The weighing sensor 30 is connected to a display screen 31.

[0017] The fixation in the text means that when the present application is in working state, the two fixed parts (such as the bin body 20 and the blocking member) can be in a relatively static state, such as existing connection methods such as welding fixation and detachable fixation.

[0018] The blocking part is located above the constraint frame. Depending on the relationship between the two,

[0019] For the purpose of firmness, the blocking member on the outer surface of the bin body 20 is a reinforcement frame 24 , which surrounds the bin body 20 .

[0020] For the purpose of firmness, a reinforcing frame 24 is fixed to the outer surface of the waist of the bin body 20 .

[0021] In order to ensure accurate measurement, there are four weighing sensors 30 disposed at the four corners of the reinforcement frame 24 .

[0022] For accurate measurement, the weighing sensor 30 is a cantilever weighing sensor, as can be seen in Chinese patent document CN117928695A. The weighing sensor 30 is fixed on the reinforcement frame 24 , and its probe contacts the detection plate 14 , and the detection plate 14 is fixed on the constraint frame 13 .

[0023] like Figure 1 In order to facilitate steering, the vehicle body 10 is only provided with a pair of wheels 11.

[0024] like Figure 1 In order to protect the display screen 31 , a protective cover 32 is fixed outside the display screen 31 .

[0025] In order to facilitate feeding, a feeding port 21 is provided on the upper side of the bin body 20 .

[0026] In order to facilitate people to enter the warehouse body 20, the upper side of the warehouse body 20 is hinged with an opening and closing plate 22, and a hydraulic support rod 23 is hinged between the opening and closing plate 22 and the warehouse body 20. Under the control of the hydraulic support rod 23, the opening and closing plate 22 is opened and closed.

[0027] In order to facilitate supporting the vehicle body 10 , a flippable support leg 12 is hingedly connected to one end of the vehicle body 10 .

[0028] Its working principle is:

[0029] S1. Transportation

[0030] After the material transfer is completed, the vehicle body 10 is connected to the tractor, and the flippable legs 12 are flipped to a high position. The tractor 10 is driven for transportation.

[0031] During transportation, the constraint frame 13 provides radial constraint for the warehouse body 20, and the warehouse body 20 will not shake radially. At the same time, the constraint frame 13 has a certain height, similar to a ring track with a vertical axis, which can prevent the warehouse body 20 from tilting. Even if the warehouse body 20 jumps up and down, it will not escape the constraint of the constraint frame 13.

[0032] After adjusting in place, flip the flip leg 12 to the low position (such as Figure 1 position) to support the tractor and the tractor can drive away.

[0033] S2, discharging

[0034] Control is performed via a display screen 31 .

[0035] Features of this application:

[0036] In this solution, the waist of the warehouse body 20 cooperates with the vehicle body 10 so that the lower part of the warehouse body 20 (the part below the restraint frame 13) can stabilize the warehouse body 20, similar to the role of a ballast stone, to prevent the warehouse body 20 from tilting / tipping.

[0037] At the same time, the weighing sensor 30 needs to bear the weight of the entire warehouse body 20, and there are complex and large forces between its fixed parts and the warehouse body 20. Providing a reinforcement frame 24 can solve this problem.

[0038] In general, the present application can ensure safety during transportation without affecting the operation of the weighing sensor, and the components for ensuring safety are a set of components together with the "load-bearing components of the weighing sensor", thus saving processing costs.

[0039] For other contents, please refer to the prior art.

[0040] The above-described embodiments are only preferred embodiments of the present invention. It should be noted that those skilled in the art may make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as within the protection scope of the present invention.
