Description

Technical Field

[0001] This utility model relates to the technical field of material conveying equipment for ship loaders, and in particular to a baffle-adjustable ship loader hopper. Background Technology

[0002] During the transportation of materials at the dock, ship loaders are used to transport materials onto transport ships. To facilitate the control of material output, an output hopper is usually installed at the output end of the ship loader. Inside the output hopper, baffles are installed to block the material and change its movement path. To adapt to different materials and conveying needs, the baffles are adjustable. However, currently, the baffles are generally adjusted for their tilt angle by bolt assemblies. Since the baffles are subject to the impact of the material, during the material conveying process, the baffles will transmit the impact force to the bolt assembly. Prolonged impact can easily damage the threads of the bolt assembly support, affecting the adjustment function and requiring frequent replacement. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a baffle-adjustable hopper for ship loaders, protecting the bolt assembly and reducing the difficulty of adjusting the adjustable baffle.

[0004] According to an embodiment of this utility model, a baffle-adjustable ship loader hopper includes a hopper body and an adjustable baffle disposed within the hopper body. The top of the adjustable baffle is rotatably connected to the hopper body. At least two first piston cylinders are fixedly disposed on the outer side of the hopper body near the bottom of the adjustable baffle. The first piston cylinders face the adjustable baffle and penetrate the side wall of the hopper body. A first piston rod is disposed inside the first piston cylinder near the adjustable baffle. A connecting rod is hinged between the first piston rod and the adjustable baffle. A second piston cylinder is disposed outside the hopper body and communicates with the plurality of first piston cylinders. A second piston rod is disposed inside the second piston cylinder. A screw assembly that drives the second piston rod to move is coaxially rotatably connected to the second piston rod. The sum of the cross-sectional areas of the plurality of first piston cylinders is greater than the cross-sectional area of ​​the second piston cylinder. A valve is also disposed between the first piston cylinder and the second piston cylinder.

[0005] Preferably, the second piston cylinder is vertically arranged and fixedly connected to the bucket body, the second piston rod is fitted with a guide fixed on the bucket body, and the screw assembly is coaxially arranged above the second piston cylinder.

[0006] More preferably, the screw assembly includes a threaded cylinder fixed to the side wall of the bucket body, an adjusting screw that cooperates with the threaded cylinder and is rotatably connected to the second piston rod, and an adjusting handwheel connected to the adjusting screw.

[0007] More preferably, the plurality of first piston cylinders are connected to the second piston cylinders via a connecting pipe, and the valve is disposed on the connecting pipe.

[0008] More preferably, the end of the connecting rod away from the adjustable baffle is provided with a connecting seat, the connecting seat is provided with a connecting hole, and the first piston rod extends into the connecting hole and is connected to it through an elastic element.

[0009] More preferably, a baffle plate is detachably connected to the side of the adjustable baffle away from the first piston rod.

[0010] In a further preferred embodiment, the side wall of the bucket body is also provided with an observation window.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This application includes a first piston cylinder and a second piston cylinder, with the sum of the hydraulic areas of the second piston cylinder being greater than that of the first piston cylinder. During adjustment, only a small force is required to drive the first piston rod through the second piston rod, thereby changing the tilt angle of the adjustable baffle. A valve is also provided. After adjustment, the valve blocks the flow of liquid in the first and second piston cylinders, preventing the impact force on the adjustable baffle from being transmitted to the second piston rod, thus protecting the bolt assembly and improving its service life.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] This utility model provides an embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, a baffle-adjustable ship loader hopper includes a hopper body 1 and an adjustable baffle 2 disposed inside the hopper body 1. The top of the adjustable baffle 2 is rotatably connected to the hopper body 1. The top of the hopper body 1 is provided with two sets of hinge seats. A hinge rod that cooperates with the hinge seats is fixedly connected to the adjustable baffle 2.

[0020] At least two first piston cylinders 3 are fixedly provided on the outer side of the bucket body 1 near the bottom of the adjustable baffle 2. The first piston cylinders 3 face the adjustable baffle 2 and penetrate the side wall of the bucket body 1. When the adjustable baffle 2 is in a vertical state, the first piston cylinders 3 are perpendicular to the adjustable baffle 2. The first piston cylinder 3 is provided with a first piston rod 301 near the adjustable baffle 2. The first piston rod 301 and the adjustable baffle 2 are hinged to a connecting rod 302.

[0021] The bucket body 1 is provided with a second piston cylinder 4 that communicates with multiple first piston cylinders 3. The second piston cylinder 4 is provided with a second piston rod 401. The second piston rod 401 is coaxially rotatably connected to a screw assembly 5 that drives it to move. The sum of the cross-sectional areas of the multiple first piston cylinders 3 is greater than the cross-sectional area of ​​the second piston cylinder 4. A valve 6 is also provided between the first piston cylinder 3 and the second piston cylinder 4.

[0022] Since the hydraulic areas formed by the first piston cylinder 3 and the second piston cylinder 4 are different, and the hydraulic area of ​​the first piston cylinder 3 is larger, the first piston rod 301 can be moved by pushing the second piston rod 401 with a smaller force, thereby changing the tilt angle of the adjustable baffle 2. After the adjustment is completed, the valve 6 is closed. When the adjustable baffle 2 is subjected to a force, the force cannot be transmitted to the second piston rod 401, so it will not have an impact effect on the screw assembly 5.

[0023] To improve the transmission stability between the screw assembly 5 and the second piston rod 401, in a further embodiment, such as... Figure 3 As shown, the second piston cylinder 4 is vertically arranged and fixedly connected to the bucket body 1. A guide 402 fixed on the bucket body 1 is sleeved on the second piston rod 401. The screw assembly 5 is coaxially arranged above the second piston cylinder 4.

[0024] In this embodiment, the guide member 402 includes a guide seat fixed on the bucket body 1. The guide seat is provided with a limiting guide hole. The second piston rod 401 passes through the guide hole and cooperates with it, so that the second piston rod 401 can only move radially in a straight line.

[0025] Specifically, such as Figure 3 As shown, the screw assembly 5 includes a threaded cylinder 501 fixed on the side wall of the bucket body 1, an adjusting screw 502 that cooperates with the threaded cylinder 501 and is rotatably connected to the second piston rod 401, and an adjusting handwheel 503 connected to the adjusting screw 502. A plurality of first piston cylinders 3 are connected to the second piston cylinders 4 through a connecting pipe 7, and the valve 6 is provided on the connecting pipe 7.

[0026] To mitigate the impact of material impact transmitted from the adjustable baffle 2 to the connecting rod 302, in a further embodiment, such as... Figure 4 As shown, the connecting rod 302 is provided with a connecting seat 303 at one end away from the adjustable baffle 2. The connecting seat 303 is provided with a connecting hole 304. The first piston rod 301 extends into the connecting hole 304 and is connected to it through an elastic element 305. In this embodiment, the elastic element 305 is a rigid spring.

[0027] In order to facilitate the adaptation to damage caused by impact and avoid frequent replacement of the adjustable baffle 2, in a further embodiment, the adjustable baffle 2 is detachably connected to a baffle liner 201 on the side away from the first piston rod 301.

[0028] In order to facilitate observation of the material inside the bucket 1, in a further embodiment, an observation window 101 is provided on the side wall of the bucket 1.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
