[0001] The utility model relates to the technical field of building material transport tools, in particular to a transport trolley used in construction sites. Background Art
[0002] As the name implies, a wheelbarrow is a device driven by manpower to transport and transfer materials. It is widely used in various fields due to its simple maintenance and convenient operation. In the field of construction engineering, wheelbarrows play a more important role. They are currently a common means of transportation on construction sites and are widely used for short-distance transportation of construction materials such as bricks, sand, cement and steel bars.
[0003] The handcarts used in construction are generally divided into frame carts and bucket carts. Frame carts can transport long non-bulk materials such as plates. As the name suggests, bucket carts are vehicles with hoppers, mainly used to transport bulk materials such as sand, concrete, etc. After unloading, the existing bucket carts pile up the bulk materials, and they need to be spread out manually with a shovel. In addition, the bucket carts currently used have electric or hydraulic automatic material turning and dropping. Although turning the material saves some effort, the structure is relatively complex and the production cost is high. In addition, due to the harsh operating environment, it is easy to malfunction and the maintenance cost is also relatively high. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a transport cart for construction sites, which consists of a bucket, handrails, and wheels. The top of the front side plate of the bucket is rotatably connected to the side plates on the left and right sides of the bucket through a first rotating shaft, and the bottom of the left and right sides of the front side plate are fixedly connected to a hook. A second rotating shaft is respectively provided at the bottom of the side plates on the left and right sides of the bucket near the front side plate. The buckle is rotatably sleeved and connected to the second rotating shaft. A torsion spring is provided between the second rotating shaft and the buckle. The buckle rotates upward clockwise under the action of the torsion spring and then is connected to the hook. One end of the pull wire is fixedly connected to the buckle, and the other end is connected to the pull ring after passing through several threading blocks. The pull ring is located at the handrail. When the pull ring is pulled, the pull wire drives the buckle to overcome the force of the torsion spring and come out of the hook.
[0006] Preferably, the threading block is a steel block with a through hole in the middle, which is welded to the side plates on both sides of the truck bed. A threading block is welded to the handrail. The pull wire passes through the through hole of the threading block and is connected to the pull ring. The pull ring is a round steel ring, and the size of the pull ring is larger than the size of the through hole.
[0007] Preferably, a leveling device is provided at the bottom of the vehicle body.
[0008] Preferably, the flattening device includes a steel pipe, a guide sleeve, a spring, a sliding sleeve, and a push plate. The two steel pipes are symmetrically and vertically fixedly connected to the outer bottom surface of the truck bed. The bottom of the steel pipe is detachably connected to the top of a guide sleeve. One end of the spring is fixedly connected to each guide sleeve. The other end of the spring extends out of the guide sleeve and is fixedly connected to the top surface of the push plate. The sliding sleeve is fixedly connected to the top surface of the push plate, and the sliding sleeve is slidably connected to the outside of the guide sleeve.

[0010] The beneficial effects of adopting the above technical solution are:
[0011] 1. In the utility model, the top of the front side plate of the truck bucket is rotated to connect the left and right side plates of the truck bucket, and the lower part uses the force of the torsion spring to buckle the buckle and the hook together, so that the front side plate is automatically fixed on the truck bucket. At the same time, the pull line is used to control the opening and closing of the buckle and the hook. The worker only needs to pull the pull ring to overcome the force of the torsion spring, pull the buckle to rotate, and disengage the buckle from the hook to dump the bulk material in the truck bucket. After dumping, the truck bucket is slightly flattened, and the front side plate of the truck bucket is attached to the truck bucket under the action of gravity, and then the pull ring is released. Under the action of the torsion spring, the buckle is automatically buckled on the hook to fix the front side plate. The whole operation is very convenient, and the structure is very simple, strong and durable, easy to maintain, and the production cost and maintenance cost are low, which is suitable for large-scale promotion.
[0012] 2. A flattening device is set under the bucket. When the unloaded bulk materials need to be spread out, the push plate will spread out the excess bulk materials as the trolley moves. The flattening work is performed while unloading, which provides convenience for the subsequent flattening work of the workers. At the same time, when the trolley only needs to transport bulk materials and does not need to be flattened, the flattening device can also be removed. The steel pipe left at the bottom of the bucket can be used as the front leg support of the trolley, which is convenient for the parking and use of the trolley. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0018] like Figure 1 As shown, the trolley is composed of a bucket 2, a handrail 1, and wheels 3. The top of the front side plate of the bucket 2 is rotatably connected to the side plates on the left and right sides of the bucket 2 through a first rotating shaft 4. Specifically, there are two first rotating shafts 4, which are welded to the left and right side plates respectively, and there are round tubes on both sides of the front side plate, which are sleeved outside the first rotating shaft 4.
[0019] like Figure 2 As shown, a hook 6 is fixedly connected to the bottom of the left and right sides of the front side plate, and a second shaft 5 is welded to the bottom of the left and right side plates of the truck bed 2 near the front side plate. The buckle 7 is a curved round tube, one end of which is rotatably sleeved on the second shaft 5 and cannot move axially. The torsion spring is sleeved on the second shaft 5, and one end is fixedly connected to the second shaft 5, and the other end is connected to the buckle 7. In the natural state of the torsion spring, the buckle 7 is clamped on the hook 6 to fix the front side plate on the truck bed 2.
[0020] A pull wire 10 is connected to the buckle 7, and a number of threading blocks 11 are welded and connected to the left and right sides of the bucket 2. The threading block 11 is a steel block with a through hole in the middle. The pull wire 10 passes through the through hole of the threading block 11. A threading block 11 is also welded and connected to the handrail 1. The pull wire 10 passes through the threading block 11 on the handrail 1 and is connected to the pull ring 12. The pull ring 12 is a circular ring, and the outer diameter of the pull ring 12 is larger than the through hole of the threading block 11. Therefore, the pull ring 12 will be stuck outside the threading block 11 to ensure that the pull wire 10 will not fall out of the threading block 11. Pulling the pull ring 12, the pull wire 10 drives the buckle 7 to overcome the force of the torsion spring and fall out of the hook 6. The front side plate rotates around the first rotating shaft 4, and its bottom can leave the bucket 2, and the bulk material can fall from the gap between the front side plate and the bucket.
[0021] In order to enable the trolley to flatten the materials during the transportation and unloading process, a flattening device 9 is provided at the bottom of the cart 2.
[0022] like Figure 3As shown, the flattening device 9 includes a steel pipe 91, a guide sleeve 92, a spring 93, a sliding sleeve 94, and a push plate 95. The two steel pipes 91 are symmetrically and vertically fixedly connected to the outer bottom surface of the cart 2. The top of the guide sleeve 92 is sleeved and connected to the steel pipe 91, and the two are fixed by a cotter pin 96. One end of the spring 93 is fixedly connected in each guide sleeve 92, and the other end of the spring 93 extends out of the guide sleeve 92 and is fixedly connected to the top surface of the push plate 95. The top surface of the push plate 95 is fixedly connected to the sliding sleeve 94, and the sliding sleeve 94 is slidably sleeved and connected to the outside of the guide sleeve 92. Among them, the push plate 95 is made of steel plate, the front part of the steel plate is set obliquely upward, and the rear part is set horizontally. When the cart moves forward, the push plate 95 pushes the accumulated bulk materials forward and flattens them.
[0023] If the flattening device 9 is not needed, the cotter pin 96 can be loosened and the flattening device 9 can be unloaded. The steel pipe 91 welded to the bucket 2 can be used as the front leg support of the handcart, which is convenient for the workers to park and use.
