Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveying equipment, in particular to a large-transmittance mesh belt machine. BACKGROUND

[0002] In the tobacco threshing and redrying production process, the wind separation bin is an important leaf and stem separation equipment, and its main function is to realize the separation of loose leaves, tobacco stems and torn leaves that are not completely separated by using the inertia and gravity of the material and the suspension force of the wind. The wind separation effect directly relates to the realization degree of the threshing index. The wind separation bin uses a high-power fan to pump wind into the lower bin body, and the wind passes through the bottom conveying mesh belt to enter the wind separation bin body to perform wind separation. At present, the wind of the wind separation bin in the workshop needs to pass through two layers of mesh belts to enter the bin body for wind separation. The transmittance of a single layer of mesh belt is only 33.3%, and the transmittance of two layers of mesh belts will be much lower than 33.3%. The conveying mesh belt seriously hinders the effective utilization rate of energy, and the formation of wind resistance affects the wind separation efficiency. At the same time, the wind resistance caused by the wind separation bin causes the wind speed in the lower bin body to decrease, and the pressure in the lower bin body is large, causing dust and gas mixed in the air flow to accumulate in the lower bin body during the wind separation process, blocking the air pipe and causing the performance of the equipment to decrease. In the prior art, how to reduce the wind resistance of the conveying mesh belt and increase the transmittance has become a major direction for improving the wind separation bin. The conventional way is to use a woven large-hole mesh to greatly improve the transmittance, or a piece of mesh can span multiple chain links to reduce the influence of the inherent part of the mesh plate on the transmittance reduction. However, these methods still need at least two layers of mesh belts, and there is still a large wind resistance. SUMMARY

[0003] The present application aims to overcome the shortcomings of the prior art, i.e., large wind resistance and small transmittance of the conveying mesh belt in the wind separation bin, and provides a large-transmittance mesh belt machine.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts are within the scope of protection of the present application.

[0028] In the description of the present application, it is also necessary to explain that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] As Figure 1 The device also includes a chain wheel system 2, a rotating shaft system 3, an inner chain 41, an outer chain 42, and a chain plate fixing frame 5. In the device, the rotating shaft system 3 is connected to the motor 7 on the conveying frame 1 as a driving action system for driving the entire device to work normally, then the chain wheel system 2 is arranged on the rotating shaft system 3, thus constituting the basic basic element of chain transmission, and finally a chain transmission system is constituted by arranging a transmission chain on the chain wheel system 2. Unlike ordinary chain type mesh belt machines, the device simultaneously and synchronously arranges the inner chain 41 and the outer chain 42 on the chain wheel system 2. It should be noted that the inner chain 41 and the outer chain 42 must be synchronously conveyed, and if there is a step difference, the mesh belt on it will be forced to be pulled apart or damaged, so that the material falls off, and the specific placement and connection of the mesh belt on the inner chain 41 and the outer chain 42 is that chain plate fixing frames 5 are arranged on the inner chain 41 and the outer chain 42 respectively, and the chain plate fixing frames 5 are arranged between the two chains. According to the mesh belt continuous connection method of the device which is different from the traditional mesh belt machine, one end of the mesh belt is connected to the chain plate fixing frame 5 of the inner chain 41, and the other end is connected to the chain plate fixing frame 5 arranged on the outer chain 42. This connection method actually divides the mesh belt into multiple pieces between every two chain plate fixing frames 5, and the pieces are not connected to each other but only fit together. Finally, through chain transmission, the inner chain 41 and the outer chain 42 are driven to rotate by the chain wheel system 2, which opens the lower layer and makes the mesh belt stand up, so that the mesh belt at the lower layer is actually connected to the outer link of the outer chain 42 at one end and to the link of the inner chain 41 at the other end. When running to the lower part, the outer chain 42 is below and the inner chain 41 is above, so that the entire mesh stands up, thereby reducing the occupation of the lower mesh surface and improving the air permeability.

[0030] The device simultaneously and synchronously arranges the inner chain 41 and the outer chain 42 on the chain wheel system 2, and opens the lower layer and makes the mesh belt stand up when the inner chain 41 and the outer chain 42 are driven to rotate by the chain wheel system 2, so that the bottom layer of the mesh belt of the mesh belt machine is opened and the wind resistance is reduced, and the air permeability is improved.

[0031] In another embodiment, how to make the inner and outer chains open the lower layer by the chain wheel system 2 when the transmission rotates, so that the mesh belt is divided and erected is a key point of the device. As shown in Figure 2 In the device, the two chains are divided into layers by the double chain mode combined with the transmission of the chain wheel system 2. Specifically, the chain wheel system 2 includes a driven wheel 21, a driving wheel 22, a first guide wheel 23, a second guide wheel 24, a third guide wheel 25, and a fourth guide wheel 26. The driven wheel 21 and the driving wheel 22 are arranged on the same horizontal plane, and the driving wheel 22 is connected to the motor 7 to provide power input. The driven wheel 21 and the driving wheel 22 are located on the same plane to facilitate the mesh belt to be on the same level, so that the entire mesh belt surface is horizontal and closed, facilitating the conveying of materials. The first guide wheel 23 and the third guide wheel 25 are arranged on the same horizontal plane and located below the driven wheel 21 and the driving wheel 22. The second guide wheel 24 and the fourth guide wheel 26 are arranged on the same horizontal plane and located below the first guide wheel 23 and the third guide wheel 25. In this way, the chain wheel system 2 is actually three layers, which are the top conveying layer and the lower separate layer. The conventional mesh belt machine actually realizes transmission by connecting the driven wheel 21, the driving wheel 22, and the chain, which only has two layers, while the upper layer of the device is unchanged. When the conventional lower layer is divided into two layers by the guide wheels on the lower side, the two chains are guided to different layers by the double chain structure at the guide wheels, so that the mesh belt is divided and erected.

[0032] In another embodiment, the double chain structure and the guide layering make the mesh belt stand at the bottom, but how to make it run normally and smoothly is also a key point. If the position of the guide wheel is not correct, it is easy to appear locked. This embodiment provides a specific chain wheel system arrangement structure, as shown in Figure 2As shown, the device sets the first guide wheel 23 at the inner side below the driving wheel 22, sets the third guide wheel 25 at the inner side below the driven wheel 21, sets the second guide wheel 24 at the inner side below the first guide wheel 23, and sets the fourth guide wheel 26 at the outer side below the third guide wheel 25 and at the inner side below the driven wheel 21. In this way, when the chain rotates counterclockwise, the inner and outer chain belts with the two chain plate holders 5 come to the bottom of the fourth guide wheel 26, and because the chain is layered at this point by the two guide wheels, the inner chain 41 moves upward through the third guide wheel 25, while the outer chain 42 continues to move downward. At this point, the chain plate holder 5 with the net belt moves upward to the middle layer, and when the inner chain 41 with the chain plate holder 5 passes through the third guide wheel 25, the outer chain 42 with the subsequent two chain plate holders 5 again comes to the bottom of the fourth guide wheel 26, and because the chain is layered at this point, the inner chain 41 moves upward through the third guide wheel 25, while the outer chain 42 continues to move downward. In this way, the front and rear chain plate holders 5 connected by a net belt are at the same time one in the upper layer and one in the lower layer, and because the inner chain 41 and the outer chain 42 are synchronized and run at the same time, the net belt can be carried in a separate open state to one side, so that the bottom can be opened without blocking the wind, reducing wind resistance. When the chain moves to the first guide wheel 23, the chain plate holder 5 on the inner chain 41 enters the matching position, and the chain plate holder 5 on the previous outer chain 42 is compounded to form an integral whole and continues to move forward, while the subsequent outer chain 42 also comes to the bottom of the second guide wheel 24 and enters the preparation stage of compounding, until it moves to the top of the first guide wheel 23 and matches with the chain plate holder 5 on the subsequent inner chain 41 to reset.

[0033] In another embodiment, in addition to counterclockwise movement, the chain can also move clockwise, and the movement direction is opposite, and the action is also opposite. Specifically, the net belt is opened at the first guide wheel 23, separated at the second guide wheel 24, and recombined at the first guide wheel 23.

[0034] In another embodiment, in order to match the wheel train and chain guide layering in the above-mentioned embodiment, the driven wheel 21, the driving wheel 22, the first guide wheel 23, and the fourth guide wheel 26 are coaxial double-wheel structures.

[0035] In another embodiment, in order to make the net belt connect two chains at the same time both in the same plane when at the top and open separately when at the bottom, the net belt is opened and combined through a chain divider 8, the chain plate fixing frame 5 is arranged on the chain divider 8, and the net belt is arranged as multiple net belts. Specifically, the chain divider 8 is arranged as a layering frame for layering the chain plate fixing frame 5, so that the chain plate fixing frame 5 can be separated when moving with the layering of the chain and combined at the top.

[0036] In another embodiment, in order to facilitate the cooperation of the net belt and the chain, the net belt is a stainless steel woven net or a punched net. A specific selection is a stainless steel woven net as a stainless steel net chain, so that it has certain supporting strength and certain tensile strength, facilitating the connection movement.

[0037] In another embodiment, a chain divider special for a large-transpiration net belt machine is provided, such as Figure 3 Figure 4 Figure 5 and Figure 6As shown, the chain divider includes an inner chain 41 and an outer chain 42. A third connecting plate 83 is connected to the outer link plate of the inner chain 41, a first connecting plate 81 is connected to the outer link plate of the outer chain 42, a second connecting plate 82 is connected to the first connecting plate 81, the first connecting plate 81 is arranged above the inner chain 41 to arrange the second connecting plate 82 opposite to the third connecting plate 83, a link plate clamping plate 87 is arranged on the second connecting plate 82, another link plate clamping plate 87 is arranged on the third connecting plate 83, and the two link plate clamping plates 87 are arranged opposite to each other. In fact, in the present chain divider, the link plate fixing frame 5 has been integrated into the device, and the link plate clamping plate 87 is used to fix the mesh belt. In the device, the first connecting plate 81 is arranged above the inner chain 41 to arrange the second connecting plate 82 opposite to the third connecting plate 83, which is the key to the normal operation of the double chains without affecting each other and enabling the link plate clamping plates 87 on the second connecting plate 82 and the third connecting plate 83 to be close and separate. If the first connecting plate 81 does not cross the inner chain 41, the two chains cannot be located on the same plane, so that the mesh belt is not flat and cannot transport materials normally. If the second connecting plate 82 and the third connecting plate 83 are not arranged opposite to each other, the two link plate clamping plates 87 cannot be close, unless other connecting components are used to eliminate the misalignment. When the two link plate clamping plates 87 are separated to separate the mesh belt, the movement is limited due to the misalignment and the addition of other components, and the mesh belt cannot be separated normally. Moreover, the two link plate clamping plates 87 are arranged opposite to each other to enable the mesh belt connected in front and back to have no gap, otherwise the gap will cause the materials to fall and increase the difficulty of transportation. Therefore, the device arranges the second connecting plate 82 opposite to the third connecting plate 83 by the first connecting plate 81 arranged above the inner chain 41, so that the mesh belt is connected to the two chains at the same time, and can be on the same plane at the top and can be opened and separated at the bottom in cooperation with the double chains. Ultimately, the mesh belt can be better separated and erected at the lower layer during transportation without affecting the normal transportation of the mesh belt, thereby reducing the wind resistance of the mesh belt and increasing the air permeability.

[0038] In another embodiment, the mesh belt of the double chain structure is separated and erected by the guide of the chain wheel system 2, and the two chains are separated by the transmission of the chain wheel system 2, so that the chains rotate during the transportation of the guide wheel. In order to facilitate movement and avoid jamming, Figure 5 As shown, one end of the first connecting plate 81 is fixedly arranged at the top of the outer link plate of the outer chain 42, and the second connecting plate 82 is rotatably arranged on the first connecting plate 81 through a rotating shaft. The third connecting plate 83 is rotatably arranged on the inner chain 41 through a rotating shaft. In this way, during operation, the connection of the mesh belt can also rotate adaptively with the rotation of the guide wheel, thereby avoiding jamming.

[0039] In another embodiment, in order to make the two chain plate clamping plates 87 well fit at the top, as shown in Figure 3 The third connecting plate 83 and the rotation center of the second connecting plate 82 are on the same axis. Thus, the two chain plate clamping plates 87 can be located in the same plane when they are fitted.

[0040] In another embodiment, in order to facilitate the connection of other components, the chain plate clamping plate 87 is easier to position and rotate, as shown in Figure 3 Figure 5 And Figure 6 The first connecting plate 81 is L-shaped, the second connecting plate 82 is L-shaped, the third connecting plate 83 is L-shaped, and the second connecting plate 82 and the third connecting plate 83 each occupy half of the rotation axis and can be fitted with each other. Thus, when the mesh belt is rotated to the top, the second connecting plate 82 and the third connecting plate 83 are positioned and fitted with each other at the gap after the chain plate clamping plate 87 is pulled and rotated, which is simple and practical, and is also convenient for movement.

[0041] In another embodiment, in order to facilitate replacement or installation adjustment, the two chain plate clamping plates 87 are fastened and arranged on the second connecting plate 82 and the third connecting plate 83 by screws.

[0042] In another embodiment, in order to facilitate the fitting of the two chain plate clamping plates 87 at the rotation of the sprocket, avoid material leakage or jamming, a lower chain plate frame 84 and an upper chain plate frame 85 are arranged at the fitting position of the two chain plate clamping plates 87, the lower chain plate frame 84 and the upper chain plate frame 85 are fitted with each other, and a hinge connection rotating structure 86 is arranged at the fitting position of the lower chain plate frame 84 and the upper chain plate frame 85, and the hinge connection rotating center is not provided with a rotating shaft. Thus, the hinge connection rotating structure 86 can make the mesh belt still fit at the rotation of the sprocket without gaps, and also facilitate the opening of the two chain plate clamping plates 87, and further facilitate the adjustment of the connection position and gap during installation according to the actual situation.

[0043] In another embodiment, due to the arrangement of the chain plate frame, the position of the two chain plate clamping plates 87 changes, and the chain plate frame needs to be repositioned. In this embodiment, the nesting center of the hinge connection rotating structure 86 is arranged on the rotation center axis of the third connecting plate 83 and the second connecting plate 82.

[0044] In another embodiment, in order to facilitate installation, a transverse link screw hole 88 is arranged on the second connecting plate 82 and the third connecting plate 83 for fastening connection.

[0045] In another embodiment, in actual use, personnel can work on the mesh belt, so the mesh belt needs a certain support strength, the device sets the lower chain plate frame 84 and the upper chain plate frame 85 as L-shaped, sets two chain plate clamping plates 87 on the inner side, and sets an auxiliary shaft 6 on the inner side chain, so as to enhance the transverse bending resistance through the L-shaped chain plate frame, the chain plate clamping plate 87 and the auxiliary shaft 6, thereby improving the support strength.

[0046] In another embodiment, as shown in Figure 5 In order to facilitate the installation and adjustment of the first connecting plate, a vertical connecting plate is arranged on the outer chain plate of the outer chain 42, and the first connecting plate 81 is arranged on the vertical connecting plate of the outer chain plate of the outer chain 42 through screw connection.

[0047] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
