Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of heat treatment equipment, and particularly relates to a trolley material blocking device and a discharging bin. BACKGROUND

[0002] The trolley edge material of a belt roaster refers to a layer of material laid on the trolley of the belt roaster through the discharging bin, which is a protective measure to effectively protect the trolley apron of the belt roaster. The height deviation caused by the thermal expansion of the track makes the existing discharging bin unable to closely fit the trolley apron. In addition, the belt roaster trolley has a left-right deviation of about 30 mm, and the on-site discharging bin is designed to be fixed. These factors jointly cause the material to frequently fall through the gap between the discharging bin and the apron to the ground during the edge material laying operation. The material falling to the ground not only causes unnecessary waste of production materials, but also may cause environmental pollution. If the material falls by chance on the belt roaster trolley, it may cause trolley blocking failure.

[0003] In order to solve the problem that the material easily falls through the gap between the discharging bin and the apron to the ground during the trolley edge material laying, there are two solutions in the related art: (1) offsetting the discharging bin as a whole to the inside of the trolley, which can effectively prevent the material from falling; (2) welding a material blocking plate on the outside of the discharging bin. Since the above solution (1) cannot ensure that the edge material covers the apron, it is easy to cause apron burning and reduce the service life of the equipment, which may bring bad economic benefits to the enterprise. Therefore, solution (2) is usually adopted.

[0004] For solution (2), in order to avoid the material blocking plate from scratching the trolley apron, a certain gap needs to be maintained between the material blocking plate and the trolley apron. However, with the increase of the use time, the gap between the trolley apron and the material blocking plate will become larger or smaller due to the deformation of the discharging bin and the trolley. If the gap becomes larger, the oxidized balls and other materials will inevitably be squeezed and broken along the gap, and the broken oxidized balls will fall onto the trolley, causing wear and tear to the trolley and unnecessary production waste. If the gap becomes smaller, the material blocking plate will interfere with the apron, and the apron will hit the material blocking plate and the discharging bin. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0043] In addition, in the utility model like the description of "first", "second" and the like is only for the purpose of description, and can not be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features.Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features.In addition, the technical solutions of various embodiments can be combined with each other, but must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0044] In the related art, there is a technical problem that the material is easy to fall off when the trolley is laid with the material.In the present application, a trolley material blocking device is provided, which can at least solve the technical problem that the material is easy to fall off when the trolley is laid with the material.

[0045] The present application will be described below in conjunction with the drawings and specific embodiments:

[0046] In order to facilitate the description of the present application, the X direction, Y direction and Z direction are perpendicular to each other, and when the trolley material blocking device 100 is used, the Z direction is the height direction, the X direction is parallel to the width direction of the trolley, and the Y direction is parallel to the running direction of the trolley.

[0047] As shown in Figures 1 to 4 The trolley material blocking device 100 includes a material blocking plate 110, a first adjusting assembly 120 and a second adjusting assembly 130.The material blocking plate 110 is used to block the material, and is arranged above the trolley fence plate 300 along the Z direction.The first adjusting assembly 120 is used to be installed on the material discharge bin, and the output end of the first adjusting assembly 120 is connected to the material blocking plate 110 to adjust the position of the material blocking plate 110 in the Z direction.The second adjusting assembly 130 is used to be installed on the material discharge bin, and the output end of the second adjusting assembly 130 is connected to the material blocking plate 110 to adjust the position of the material blocking plate 110 in the X direction.

[0048] Thus, the distance between the material blocking plate 110 and the trolley apron 300 in the Z direction can be flexibly adjusted by the first adjusting assembly 120, so that the distance between the material blocking plate 110 and the trolley apron 300 in the Z direction meets the requirement that the material cannot fall from between the material blocking plate 110 and the trolley apron 300, and also meets the requirement that the material blocking plate 110 does not interfere with the trolley apron 300. When the trolley deviates in the X direction, the position of the material blocking plate 110 in the X direction can be adjusted in real time by the second adjusting assembly 130 according to the position of the trolley apron 300 in the X direction, so that the lower end of the material blocking plate 110 is located directly above the apron, so that the material cannot fall from between the material blocking plate 110 and the trolley apron 300, further reducing the risk of material falling. Therefore, by the design of the first adjusting assembly 120 and the second adjusting assembly 130, the distance between the material blocking plate 110 and the trolley apron 300 can be within a suitable range, and the material blocking plate 110 can always be located directly above the trolley apron 300, solving the problem of material falling during the laying of the edge material of the pellet belt-type indurating machine, reducing the waste of material and the pollution to the environment, avoiding the blocking of the trolley caused by the falling material, and helping to ensure the stable operation of the production line.

[0049] The structures of the first adjusting assembly 120 and the second adjusting assembly 130 are various, and can be manual adjustment or electric adjustment. If the first adjusting assembly 120 and the second adjusting assembly 130 are manually adjusted, a screw nut mechanism or the like can be used to achieve the adjustment. If the first adjusting assembly 120 and the second adjusting assembly 130 are electrically adjusted, a hydraulic cylinder, an air cylinder or a linear motor can be used to achieve the adjustment, which is not limited in the present application.

[0050] In some embodiments, the first adjusting assembly 120 includes a mounting seat 121, a first connecting piece 122, a second connecting piece 123 and an elastic piece 124. The mounting seat 121 is used to be mounted on the discharging bin; the first connecting piece 122 is mounted on the mounting seat 121; the second connecting piece 123 is movably connected to the first connecting piece 122; the elastic piece 124 is sleeved on the first connecting piece 122, and the material blocking plate 110 is movably arranged between the second connecting piece 123 and the elastic piece 124 in the Z direction and the X direction, and the elastic piece 124 acts on the mounting seat 121 and the material blocking plate 110.

[0051] When the trolley material blocking device 100 is used, the mounting seat 121 is fixedly connected to the lower stock bin. The second connecting piece 123 is movably connected to the first connecting piece 122, and the second connecting piece 123 can move along the length direction of the first connecting piece 122 and can be fixed at a position after moving to the position. The elastic piece 124 is sleeved outside the first connecting piece 122 and located between the mounting seat 121 and the material blocking plate 110. The elastic piece 124 is always in a compressed state, one end of the elastic piece 124 abuts against the mounting seat 121, and the other end abuts against the material blocking plate 110. Under the elastic force of the elastic piece 124, the spring presses the material blocking plate 110, and the material blocking plate 110 presses the second connecting piece 123. In the X direction, the material blocking plate 110 is movably arranged between the second connecting piece 123 and the elastic piece 124, so that the material blocking plate 110 can move in the X direction under the driving of the second adjusting assembly 130, so as to adjust the position of the material blocking plate 110 in the X direction. In the Z direction, the material blocking plate 110 is movably arranged between the second connecting piece 123 and the elastic piece 124, so that the material blocking plate 110 can move in the Z direction under the driving of the first adjusting assembly 120, so as to adjust the position of the material blocking plate 110 in the Z direction. After such design, the position of the second connecting piece 123 is adjusted, and the position of the material blocking plate 110 in the Z direction is adjusted, that is, the height of the material blocking plate 110 is adjusted. After such design, since the elastic piece 124 can be compressed and deformed, when the setting position of the movable material blocking plate 110 is relatively low and interferes with the movement of the trolley fence plate 300, after the trolley fence plate 300 collides with the material blocking plate 110, the material blocking plate 110 can drive the elastic piece 124 to be compressed, and the elastic piece 124 can play a role of buffering and absorbing energy, thereby reducing the impact energy received by the material blocking plate 110 and prolonging the service life of the material blocking plate 110.

[0052] As shown in Figure 1 and Figure 3 In some embodiments, one end of the material blocking plate 110 close to the trolley fence plate 300 is provided with a guide inclined surface 110a. That is, in the Z direction, the lower end of the material blocking plate 110 is provided with the guide inclined surface 110a. After such design, the lower end surface 110b of the material blocking plate 110 can be adjusted to be lower than the upper surface 300a of the trolley fence plate 300, and after the trolley moves, the trolley fence plate 300 contacts the guide inclined surface 110a. Due to the cooperation of the inclined surface, the material blocking plate 110 is driven to move upward and the elastic piece 124 is compressed. Under the action of the elastic piece 124, the lower end surface 110b of the material blocking plate 110 can be attached to the upper surface 300a of the fence plate, so that a gap between the material blocking plate 110 and the trolley fence plate 300 is not needed, and the risk of ball falling caused by the gap between the material blocking plate 110 and the trolley fence plate 300 is reduced.

[0053] In some embodiments, the lower ends of the two sides of the material blocking plate 110 are provided with guide inclined surfaces 110a in the X direction.

[0054] In some embodiments, the second connecting member 123 is screwed to the first connecting member 122. In this way, the position of the material blocking plate 110 in the Z direction can be adjusted by screwing the second connecting member 123, which facilitates the use of the user.

[0055] In some embodiments, the first connecting member 122 is a bolt, the second connecting member 123 is a nut, the mounting seat 121 is provided with a bolt mounting hole, the first connecting member 122 is arranged in the bolt mounting hole, the second connecting member 123 is screwed to the first connecting member 122, and the elastic member 124 is a spring, which is sleeved on the screw rod of the bolt, the upper end of which abuts against the mounting seat 121, and the lower end of which abuts against the material blocking plate 110. By screwing the second connecting member 123, the height of the material blocking plate 110 can be adjusted.

[0056] In some embodiments, the material blocking plate 110 includes a material blocking plate body 111 and a connecting plate 112. The material blocking plate body 111 is used for blocking materials and is arranged above the trolley apron 300; the connecting plate 112 is connected to the side of the material blocking plate body 111 close to the mounting seat 121 and is movably arranged between the second connecting member 123 and the elastic member 124 in the Z direction and the X direction. The connecting plate 112 is fixedly connected to the material blocking plate body 111. In this way, the material blocking plate body 111 and the connecting plate 112 can be independently processed, and after being processed, they are connected to form the material blocking plate 110, which facilitates the manufacturing of the material blocking plate 110.

[0057] In some embodiments, the material blocking plate 110 has a connecting hole 112a, and the material blocking plate 110 is movably sleeved outside the first connecting member 122 through the connecting hole 112a. The first connecting member 122 is arranged in the connecting hole 112a, and the size of the connecting hole 112a is greater than that of the first connecting member 122, so that after the material blocking plate 110 is sleeved outside the first connecting member 122 through the connecting hole 112a, it can still move in the Z direction and the X direction.

[0058] As Figure 1 and Figure 3As shown, in some embodiments, the second adjusting assembly 130 comprises a mounting bracket 131, an abutting mechanism 132, a third connecting piece 133 and a fourth connecting piece 134. The mounting bracket 131 has a mounting hole 131a, and the mounting bracket 131 is used to be mounted on the stock bin. The abutting mechanism 132 is arranged in the mounting hole 131a and connected with the material blocking plate 110. The third connecting piece 133 and the fourth connecting piece 134 are both movably connected with the abutting mechanism 132 along the X direction and arranged on both sides of the mounting bracket 131. In this way, the third connecting piece 133 and the fourth connecting piece 134 clamp the mounting bracket 131 together, so that the abutting mechanism 132, the third connecting piece 133 and the fourth connecting piece 134 can be fixed on the mounting bracket 131 as a whole. Under the action of the third connecting piece 133 and the fourth connecting piece 134, the abutting mechanism 132 is movably connected with the mounting bracket 131 along the X direction. The operator can adjust the position of the third connecting piece 133 and the fourth connecting piece 134 to adjust the position of the abutting mechanism 132 along the X direction, so as to adjust the position of the material blocking plate 110 along the X direction, which is convenient for the operator to adjust.

[0059] In some embodiments, the mounting hole 131a is a strip-shaped hole extending along the height direction, and the abutting mechanism 132 comprises a movable piece 1321 and a connecting seat 1322. The movable piece 1321 is arranged in the mounting hole 131a, and the third connecting piece 133 and the fourth connecting piece 134 are both movably connected with the movable piece 1321. The connecting seat 1322 is used to be mounted on the material blocking plate 110, and the movable piece 1321 is slidably connected with the connecting seat 1322 along the Z direction. In this way, the position of the movable piece 1321, the third connecting piece 133 and the fourth connecting piece 134 along the Z direction can be adjusted, which is convenient for the operator of different heights to adjust the third connecting piece 133 and the fourth connecting piece 134, and is convenient for the user to use.

[0060] In some embodiments, the movable piece 1321 has an external thread, and the third connecting piece 133 and the fourth connecting piece 134 are both nuts, and the third connecting piece 133 and the fourth connecting piece 134 are threadedly connected with the movable piece 1321.

[0061] In some embodiments, in order to improve the stability of the material blocking plate 110, a plurality of first adjusting assemblies 120 and / or a plurality of second adjusting assemblies 130 are arranged on the material blocking plate 110 along the Y direction at intervals.

[0062] Based on the same inventive concept, the application further provides a discharging warehouse, which comprises a discharging warehouse body 200 and two trolley material blocking devices 100. The discharging warehouse body 200 is provided with a discharging port; the first adjusting assembly 120 and the second adjusting assembly 130 of the trolley material blocking device 100 are both mounted on the discharging warehouse body 200, and the two material blocking plates 110 are oppositely arranged, with the discharging port being located between the two material blocking plates 110. The two material blocking plates 110 are both located above the two trolley side plates 300 of the trolley. The discharging warehouse body 200 is used for storing materials, and can comprise a material bin, a control valve and the like, which are various in structure and known to those skilled in the art, and are not limited in the application.
