Description

TECHNICAL FIELD

[0001] The utility model relates to the field of metal powder metallurgy technology, more specifically, it relates to powder conveying cart. BACKGROUND

[0002] Powder metallurgy is a kind of technology by pressing metal powder or mixture of metal and non-metal powder into shape and sintering at high temperature to manufacture metal material, composite material and various types of products, its process includes powder preparation, powder forming, sintering and post-processing. No matter which link, it is inevitable to involve the transportation of metal powder, even if there is a complete production line conveying system, because the structure, area, production line process and many other factors of workshop lead to that full automatic transportation is unrealistic, and it still needs to cooperate with powder conveying cart.

[0003] The existing powder conveying cart generally uses standard flat trolley or tipping cart directly, in order to meet more use requirements, it is designed into folding structure, and it is also designed into multi-layer structure. But in different periods, the transportation form of metal powder is also different, for example, there are bagged, box-shaped, barrel-shaped forms in powder preparation process. For different transportation forms, although the existing trolley tool can also complete transportation, the space utilization rate of trolley in single trip is low, and the powder and its carrier are easy to fall off or be damaged, if the powder is poured into the trolley, the loading and unloading are also more troublesome. In addition, when conveying barrel-shaped powder, if the size of outer barrel is too large, it is necessary to specially replace the corresponding type of trolley, which is very inconvenient.

[0018] Embodiment:

[0019] The following will be combined with the Figures 1-4 The utility model will be further described in detail.

[0020] The powder conveying cart, such as Figure 1 and Figure 2As shown, the main body is a box trolley 1 with universal wheels, which are provided with brake for stopping. The box trolley 1 is provided with open side cavities 2 on both sides and an open main cavity 4 on the top. The main cavity 4 and the side cavities 2 are not connected. Each side cavity 2 is provided with an outwardly slidable outer barrier 3. The box trolley 1 is provided with a discharge port 6 connected to the main cavity 4 at the rear end and a discharge valve 5 connected to the main cavity 4 at the front end.

[0021] As shown, Figure 3 the cross section of the side cavity 2 is a prismatic structure. Specifically, the bucketed powder can be placed obliquely from the outside and then falls into the side cavity 2. The bottom surface of the side cavity 2 is horizontal and has a stepped layer, that is, the horizontal bottom surface and the adjacent folded edge are not continuous, but an additional vertical surface is provided, which is used as the termination point of the subsequent sliding rail 7 and the blocking plate for the inward sliding of the outer barrier 3. The innermost side surface of the side cavity 2 is inclined. The cross section of the outer barrier 3 is a straight triangle structure, and the inner side surface is inclined. The inclination angles of the inner side surface of the outer barrier 3 and the inner side surface of the side cavity 2 are consistent, that is, they are arranged in parallel. Preferably, when the outer barrier 3 abuts against the vertical surface of the stepped layer, the inner side surface of the outer barrier 3 and the inner side surface of the side cavity 2 can be closely fitted. The bottom surface of the side cavity 2 is provided with an array of three sliding rails 7, and the outer end of the sliding rail 7 is provided with a protruding holder for preventing the outer barrier 3 from sliding off the sliding rail 7. The corresponding outer barrier 3 is provided with the same number of sliding rail grooves 8 at the bottom, and the end of the sliding rail groove 8 is provided with a tapered holder, which cooperates with the holder of the sliding rail 7 to block and limit the outward sliding of the outer barrier 3. As shown, Figure 4 the outer barrier 3 and the corresponding side cavity 2 are connected by sliding the sliding rail 7 and the sliding rail groove 8, and can slide outwardly or inwardly along the sliding rail 7. Although the outer barrier 3 cannot be separated in the horizontal direction, there is still a risk in the vertical direction. Therefore, protruding clamping blocks 9 are arranged on the front and rear end surfaces of the side cavity 2, and the front and rear end surfaces of the outer barrier 3 are provided with horizontally arranged and through rear end side clamping grooves 10 corresponding to the clamping blocks 9. The clamping grooves 10 are arranged corresponding to the clamping blocks 9, which not only assist the sliding direction of the outer barrier 3, but also limit and prevent the outer barrier 3 from being separated in the vertical direction. In addition, in order to prevent the outer barrier 3 from providing sufficient support force to fix the bucketed powder and avoid the outer barrier 3 from sliding freely due to shaking during transportation, a plurality of elastic members are arranged at the corresponding position of the vertical surface of the stepped layer and the inner end of the outer barrier 3, which additionally constrain the pulling. The main cavity 4 is a funnel structure as a whole, and the bottom is horizontal and provided with a discharge valve 5 and a discharge port 6. The main cavity 4 can directly pour powder, or can be filled with bagged or boxed powder.

[0022] When in use, the main cavity 4 and the side cavity 2 are used separately, the main cavity 4 is used for containing bulk, box or bag metal powder, and the side cavity 2 is used for containing barrel powder. The outer stopper 3 in the side cavity 2 can be adjusted in sliding according to the size of the barrel powder, the expanded outer stopper 3 can not only adapt to the size of the barrel, but also provide additional compression force inwardly to strengthen the fixation. The front end discharge valve 5 is used for controllably discharging powder material to other equipment or container, and the rear end discharge port 6 is used for emergency discharge of powder to prevent the deterioration of explosion and the like.

[0023] It should be noted that the specific embodiments are merely an explanation of the present application, and are not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, as long as the modifications are within the scope of the claims of the present application.
