Description

Technical Field

[0001] The invention relates to the field of construction, and more particularly to a labor-saving concrete discharging device. Background Art

[0002] The term concrete refers to cement as the binder, sand and stone as aggregates, mixed with water (which may contain admixtures and additives) in a certain proportion and stirred. It is also called ordinary concrete and is widely used in civil engineering.

[0003] During construction in buildings and other places, the concrete production company needs to transport the mixed concrete to the construction site, and use buckets and other devices to transport the concrete to the corresponding height of the floor. Then the construction workers load a certain amount of concrete in mud buckets to carry out wall, wall, floor and other construction operations. Although it is quick and convenient to use concrete loaded in mud buckets, workers need to bend over frequently and carry mud buckets during construction, which is very laborious. Therefore, it is necessary to improve the concrete construction method to make it more labor-saving to use. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a labor-saving concrete discharging device, which does not require frequent bending and other operations, is more labor-saving and more practical.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A labor-saving concrete discharging device comprises a cart, a discharging pressure rod and a discharging hose, a mud bucket is placed on the upper surface of the cart, and a handlebar is welded at one end of the upper surface of the cart, a support plate is nested on the outer side of the handlebar, the support plate and the handlebar are welded and fixed, and a limiting hole is provided at one end of the support plate, the discharging pressure rod passes through the limiting hole, and the bottom end of the discharging pressure rod is inserted into the mud bucket, a pipe bin is provided inside the discharging pressure rod, and a pipe through hole is provided on one side of the top end of the discharging pressure rod, the pipe through hole is connected to the pipe bin, and the discharging hose passes through the pipe bin.

[0007] Furthermore, the top end of the discharge hose passes through the tube hole, and a discharge nozzle is embedded in the top end of the discharge hose, and a feed nozzle is embedded in the bottom end of the discharge hose, and the feed nozzle is installed at the bottom of the discharge pressure rod by screwing.

[0008] Furthermore, a barrel positioning plate is welded on the upper surface of the cart, and the mud barrel is placed on the upper surface of the cart close to one side of the barrel positioning plate, and the diameter of the pressure plate is consistent with the inner diameter of the mud barrel.

[0009] Furthermore, an underarm support plate is welded to the top end of the discharge pressure rod, and a rubber soft bag is bonded and fixed to the upper surface of the underarm support plate.

[0010] Furthermore, a push handle is fixed to the top of the handlebar.

[0011] Compared with the prior art, the advantages of the present invention are: This solution uses a cart to store mud buckets, and a discharge pressure rod is arranged above the corresponding mud bucket. A discharge hose runs through the inside of the discharge pressure rod. When in use, the worker places the underarm support plate on the top of the discharge pressure rod under the armpit and presses the underarm support plate downward by his own gravity. The concrete in the mud bucket flows out from the discharge nozzle at one end of the discharge hose under pressure. The worker then uses a trowel to catch the flowing concrete and can carry out construction operations such as wall laying. There is no need to frequently bend over, which is more labor-saving and more practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0015] See also Figure 1-Figure 6A labor-saving concrete discharging device includes a cart 101, a discharging pressure rod 103 and a discharging hose 105. A mud bucket 104 is placed on the upper surface of the cart 101, and a handlebar 102 is welded at one end of the upper surface of the cart 101. A support plate 122 is embedded on the outer side of the handlebar 102. The support plate 122 and the handlebar 102 are welded and fixed, and a limiting hole 123 is opened at one end of the support plate 122. The discharging pressure rod 103 passes through the limiting hole 123. The arrangement ensures that when the discharge pressure rod 103 moves up and down, the horizontal position of the discharge pressure rod 103 will not be offset, and the bottom end of the discharge pressure rod 103 is inserted into the mud bucket 104, a pipe bin 135 is provided inside the discharge pressure rod 103, and a pipe through hole 134 is provided on one side of the top end of the discharge pressure rod 103, the pipe through hole 134 is connected to the pipe bin 135, and the discharge hose 105 passes through the pipe bin 135. This arrangement facilitates the cement to flow out of the discharge hose 105.

[0016] See also Figure 1-Figure 6 The top of the discharge hose 105 passes through the pipe perforation 134, and a discharge nozzle 151 is nested at the top of the discharge hose 105, and a feed nozzle 152 is nested at the bottom of the discharge hose 105. The feed nozzle 152 is installed at the bottom of the discharge pressure rod 103 by threaded engagement. This arrangement facilitates the flow of cement from the discharge hose 105.

[0017] See also Figure 1-Figure 6 A barrel positioning plate 111 is welded on the upper surface of the cart 101, and the mud barrel 104 is placed on the upper surface of the cart 101 close to one side of the barrel positioning plate 111. This arrangement allows the mud barrel 104 to be aligned with the center of the discharge pressure rod 103, and the diameter of the pressure plate 133 is consistent with the inner diameter of the mud barrel 104. This arrangement allows the gap between the pressure plate 133 and the mud barrel 104 to be smaller. When the pressure plate 133 is squeezed into the mud barrel 104, cement flows out smoothly from the discharge hose 105.

[0018] See also Figure 1 and Figure 3 An underarm support plate 131 is welded to the top of the discharge pressure rod 103, and a rubber soft bag 132 is bonded and fixed to the upper surface of the underarm support plate 131. This arrangement makes it more comfortable for workers to squeeze the underarm support plate 131 downward through their armpits.

[0019] See also Figure 1 A push handle 121 is fixed to the top of the handlebar 102, and this arrangement makes it easy to move the cart 101.

[0020] During use: first lift up the discharge pressure rod 103, remove the mud bucket 104, fill the mud bucket 104 with concrete, then put the mud bucket 104 back, and then put down the discharge pressure rod 103. At this time, the worker puts the armpit support plate 131 under his armpit, holds the discharge nozzle 151 with one hand, and holds the mud knife with the other hand. The arm holding the armpit support plate 131 presses the armpit support plate 131 downward. At this time, the concrete inside the mud bucket 104 enters the discharge hose 105 from the feed nozzle 152, and finally flows out from the discharge nozzle 151. The concrete flowing out of the discharge nozzle 151 is spread on the mud knife, and the concrete is applied to the required construction area with the mud knife; repeat the above operation to repeatedly apply concrete.

[0021] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
