However, when the column is poured too high at one time, the free fall will cause concrete segregation, resulting in quality problems such as concrete root rot and honeycomb. In addition, the discharge port of the existing concrete hopper cannot effectively control the discharge flow rate. Utility Model Content

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0024] like Figure 1-4 As shown, the utility model proposes a new type of concrete hopper, including a hopper body 1, the upper part of the hopper body 1 is connected to the crane hook through a cable 11, and the lower part of the hopper body 1 is fixedly installed on a bracket 12. A sealing baffle 14 is rotatably installed at the discharge port 10 through a rotating shaft 41, and the discharge port 10 of the hopper body 1 is directly connected to the casting template through a delivery pipe 13. Compared with the prior art in which the hopper can only pour concrete from the top due to the dense steel bar group in the template, the delivery pipe 13 of the device passes through the steel bar group to directly transport the concrete to the casting site, and the flow rate of the concrete can be effectively adjusted by controlling the opening and closing degree of the sealing baffle 14, thereby effectively solving the problems of being affected by the steel bars during concrete pouring and the excessive height of the free fall, thereby improving the pouring and molding quality of the concrete.

[0025] One end of the rotating shaft 41 is movable and penetrates outside the hopper body 1. The end of the rotating shaft 41 extending outside the hopper body 1 is vertically fixedly connected with a pressure rod 44. One end of the first control rope 71 is fixedly connected to the pressure rod 44. The other side of the pressure rod 44 away from the first control rope 71 is connected to the hopper body 1 through the first tension spring 42; the other end of the first control rope 71 is controlled by the ground controller after passing through the pulley assembly. Pulling the first control rope 71 and swinging the pressure rod 44 can effectively control the opening and closing degree of the sealing baffle 14. The first tension spring 42 can provide a restoring force for the pressure rod 44 to reset.

[0026] The hopper body 1 is fixed with a limit plate 5. When the pressure rod 44 is pulled by the first tension spring 42 and abuts against the limit plate 5, the sealing baffle 14 is in a horizontal state, and the discharge port 10 can be completely closed. A limit rod 9 with adjustable length is vertically installed on the bracket 12. When the pressure rod 44 is pulled to the bottom and abuts against the top of the limit rod 9 by the pull of the first control rod, the sealing baffle 14 is in the maximum opening and closing state. In the present application, the limit rod 9 includes a sleeve 91, a screw 93 and an adjustment sleeve 92. The sleeve 91 is fixed on the bracket 12. The screw 93 is slidably sleeved in the sleeve 91 up and down. The outer wall of the screw 93 is provided with a slide groove 931 along its length direction. The inner wall of the sleeve 91 is provided with a limit block. The limit block is slidably clamped in the slide groove 931. The adjustment sleeve 92 is rotatably installed at the opening of the sleeve 91 and is threadedly sleeved with the screw 93. With the sliding cooperation between the limit block and the slide groove 931, the screw 93 can only slide up and down. By rotating the adjusting sleeve 92, the screw 93 can be driven to telescope in the sleeve 91, and the elongation of the screw 93 can be adjusted, thereby limiting the maximum downward swing angle of the pressure rod 44, thereby setting the maximum opening and closing angle of the sealing baffle 14, and effectively controlling the discharge flow rate of the hopper.

[0027] The top of the screw rod 93 is provided with a support block 932 that cooperates with the pressure rod 44. The support block 932 and the limit plate 5 are both fixed with a rubber pad that cooperates with the pressure rod 44, which can avoid rigid contact between the pressure rod 44 and the screw rod 93 and the limit plate 5.

[0028] The rotating shaft 41 is also provided with a locking assembly 6. The locking assembly 6 includes a ratchet 61, a swinging rod 62 and a second tension spring 63. The ratchet 61 is concentrically fixed to the outer end of the rotating shaft 41. One end of the swinging rod 62 is provided with a pawl 621 that cooperates with the ratchet 61. The tension spring is fixed between the pawl 621 and the hopper body 1. The middle part of the swinging rod 62 is rotatably installed on the hopper body 1. The other end of the swinging rod 62 is fixed to the second control rope 72. The second control rope 72 is controlled by the controller after passing through the pulley assembly. When the pressure rod 44 drives the rotating shaft 41 to rotate and control the opening and closing of the sealing baffle 14, the rotation of the pressure rod 44, the rotating shaft 41 and the sealing baffle 14 can be effectively locked through the cooperation of the pawl 621 and the ratchet 61. The controller does not need to always pull the first control rope 71, which is more labor-saving and convenient. When the sealing baffle 14 needs to be closed and reset, the swing rod 62 is driven to rotate by the second control rope 72 to unlock the ratchet 61 and the pawl 621. The pressure rod 44, the sealing baffle 14, etc. can be rotated and reset under the pulling of the first tension spring 42, which is very convenient to use.

[0029] The pulley assembly includes two guide pulleys 32 installed in the pulley box 3 and respectively corresponding to the two control ropes, and the two control ropes are wound around the guide pulleys 32. A limit pulley 31 is also installed in the pulley box 3, and the limit pulley 31 is tangentially arranged with the corresponding guide pulley 32, and the two control ropes pass through the corresponding limit pulley 31 and the guide pulley 32. The two control ropes are wound around the guide pulley 32 to effectively guide the control ropes, avoiding friction with the hopper body 1 and the bracket 12 and other structures, and the limit pulley 31 can effectively limit the sliding of the control rope in the guide pulley 32, avoiding the control rope from derailing from the guide pulley 32, and improving stability.

[0030] When using the utility model, a crane is used to lift the device above the formwork via the cable 11, the lower end of the feed pipe 13 is delivered to the casting site, and the first control rope 71 is pulled to control the opening angle of the sealing baffle 14, so that the concrete material is smoothly delivered to the formwork. When it is necessary to reduce the amount of material discharged or close the sealing baffle 14, the two control ropes are controlled to release the lock of the ratchet 61 and the pawl 621, so that under the elastic force of the first tension spring 42, the pressure rod 44, the sealing baffle 14, etc. can be reversed and reset.
