Description

Technical Field

[0001] The utility model relates to an iron removing mechanism for a cotton grabbing machine. Background Art

[0002] A cotton grabbing machine, also known as a bale plucker, is a machine that grabs cotton fibers from cotton bales in an opening and cleaning cotton combined unit. It has up-grabbing type and down-grabbing type; trolley reciprocating type, trolley (or bale table) rotary type: trolley lifting type, platform lifting type, etc. Generally, a blade (or saw blade) beater and ribs are used, and sometimes spike parts or spring pliers are used to grab fibers from the surface of the cotton bale, and the fibers are conveyed to the subsequent machines for further processing by air flow or machinery.

[0003] Since the cotton material output by the reciprocating cotton grabbing machine may be mixed with metal chips, and because the cotton material is a flammable substance, sparks are generated when the metal chips collide with the pipeline during the transportation of the cotton material in the pipeline, which may ignite the cotton material, posing a safety hazard. Moreover, the metal chips will cause wear and tear on the fan impeller of the cotton conveying fan, reducing the service life of the cotton conveying fan. Content of the Utility Model

[0004] The utility model makes improvements to the above-mentioned existing technical problems, that is, the technical problem to be solved by the utility model is to provide an iron removing mechanism for a cotton grabbing machine.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: an iron removing mechanism for a cotton grabbing machine, which includes a cotton conveying pipeline connected to the telescopic cotton conveying box of the reciprocating cotton grabbing machine. An iron removing pipe is connected between one end of the cotton conveying pipeline and the air inlet end of the cotton conveying fan. An annular electromagnet for adsorbing metal chips is arranged on the inner peripheral side of the iron removing pipe.

[0006] Further, the iron removing pipe includes an iron removing pipe body in a frustum shape. The large-diameter end of the iron removing pipe body faces the cotton conveying pipeline, and the small-diameter end faces the cotton conveying fan; the shape of the electromagnet is the same as that of the iron removing pipe body, and the electromagnet is arranged on the conical surface of the iron removing pipe body and is coaxially distributed with the iron removing pipe body.

[0007] Further, the large-diameter end of the iron removing pipe body is provided with an annular flange. An annular groove for accommodating metal chips is arranged at the inner side end of the annular flange. The diameter of the annular groove is larger than the diameter of the large-diameter end of the iron removing pipe body. A discharge port is opened at the bottom of the annular groove, and the discharge port is connected with a discharge assembly.

[0008] Further, the discharge assembly includes a storage box, a discharge pipe, an air inlet pipe and an air inlet fan. One end of the discharge pipe is connected to the discharge port and the other end is connected to the storage box. The air inlet pipe is obliquely connected to one end of the discharge pipe close to the discharge port. The air outlet end of the air inlet fan is connected to the air inlet pipe. The air flow output by the air inlet fan flows through the air inlet pipe and the discharge pipe in sequence to the storage box to suck the metal chips in the annular groove.

[0009] Furthermore, a control valve is installed at one end of the discharge pipe close to the discharge port.

[0010] Furthermore, the large diameter end of the iron removal pipe body is connected to the cotton transport pipeline through a first pipe joint, the air inlet end of the cotton transport fan is connected to an input pipe, and the input pipe is connected to the small diameter end of the iron removal pipe body through a second pipe joint.

[0011] Compared with the prior art, the utility model has the following effects: the utility model has a reasonable structural design. A deironing pipe is arranged between the cotton conveying pipe and the cotton conveying fan, and a ring-shaped electromagnet is arranged inside the deironing pipe. When the cotton flow passes through the deironing pipe, metal chips mixed in the cotton flow are adsorbed by the electromagnet, thereby removing the metal chips in the cotton flow.

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0017] like Figures 1 to 3As shown in the figure, an iron removal mechanism of a bale opener of the present utility model includes a cotton conveying pipeline 101 communicated with the telescopic cotton conveying box of the reciprocating bale opener 100. A ferrous removal pipe 103 is connected between one end of the cotton conveying pipeline 101 and the air inlet end of the cotton conveying fan 102. An annular electromagnet 104 for adsorbing metal chips is arranged on the inner peripheral side of the ferrous removal pipe 103. The electromagnet is energized to generate magnetism to adsorb metal chips. By arranging a ferrous removal pipe between the cotton conveying pipeline and the cotton conveying fan and arranging an annular electromagnet on the inner peripheral side of the ferrous removal pipe, when the cotton flow passes through the ferrous removal pipe, the metal chips mixed in the cotton flow are adsorbed by the electromagnet, so as to remove the metal chips in the cotton flow. The structure is simple, which can avoid causing great damage to the fan impeller of the cotton conveying fan and reduce potential safety hazards. Since the annular electromagnet is arranged on the peripheral side of the ferrous removal pipe, the influence of the electromagnet on the flow of the cotton flow is effectively reduced.

[0018] In this embodiment, the ferrous removal pipe 103 includes a frustum-shaped ferrous removal pipe body 109. One end of the ferrous removal pipe body 109 close to the cotton conveying pipeline 101 has a larger diameter (i.e., the large diameter end), and one end close to the cotton conveying fan 102 has a smaller diameter (i.e., the small diameter end). The large diameter end of the ferrous removal pipe body 109 faces the cotton conveying pipeline 101, and the small diameter end faces the cotton conveying fan 102. The shape of the electromagnet 104 is the same as that of the ferrous removal pipe body 109, which is also frustum-shaped. The electromagnet 104 is arranged on the conical surface of the ferrous removal pipe body 109, and the electromagnet and the ferrous removal pipe body are coaxially distributed. By arranging both the ferrous removal pipe and the electromagnet in a frustum shape, when the cotton flow output from the cotton conveying pipeline enters the ferrous removal pipe, due to the reduction of the cross-sectional area of the flow path at the position of the ferrous removal pipe, the cotton flow can better contact the electromagnet after entering the ferrous removal pipe, which is convenient for the electromagnet to adsorb the metal chips in the cotton flow and improves the iron removal effect.

[0019] In this embodiment, an annular flange 110 is provided at the large diameter end of the ferrous removal pipe body 109. An annular groove 111 for accommodating metal chips is provided at the inner side end of the annular flange 110. The annular groove is communicated with the inner cavity of the ferrous removal pipe body. The diameter of the annular groove 111 is larger than the diameter of the large diameter end of the ferrous removal pipe body 109. During the cotton flow conveying process, since the electromagnet is energized to generate magnetism, the metal chips in the cotton flow can be adsorbed at this time. After the bale opening is completed, the electromagnet is powered off, and the metal chips adsorbed on the electromagnet lose magnetic adsorption and fall on the inner conical surface of the electromagnet. And because the diameter of the annular groove is larger than the diameter of the large diameter end of the ferrous removal pipe body, some larger metal chips can slide into the annular groove by the action of gravity at this time. A discharge port 112 is opened at the bottom of the annular groove 111, and the discharge port 112 is connected with a discharge assembly 113, and the discharge assembly can discharge the metal chips in the annular groove.

[0020] In this embodiment, the discharging assembly 113 includes a storage box 114, a discharging pipe 115, an air inlet pipe 116, and an air inlet fan 117. One end of the discharging pipe 115 is connected to the discharge port 112, and the other end of the discharging pipe 115 is connected to the storage box 114. The air inlet pipe 116 is obliquely connected to one end of the discharging pipe 115 close to the discharge port 112, and the air outlet direction of the air inlet pipe 116 faces the side where the storage box is located inside the discharging pipe 115. The air outlet end of the air inlet fan 117 is connected to the air inlet pipe 116, and the air inlet fan conveys air flow into the air inlet pipe. The air flow output by the air inlet fan 117 flows through the air inlet pipe 116 and the discharging pipe 115 in sequence to reach the storage box 114. At this time, a negative pressure is formed at the discharge port, and the metal chips in the annular groove 111 are sucked into the discharging pipe 115 by using the negative pressure. The metal chips enter the storage box 114 along the discharging pipe 115. It should be noted that an exhaust port is provided at the top of the storage box. By using the air inlet fan to convey air flow into the storage box to form a negative pressure at the discharge port, it is convenient for the metal chips in the annular groove to be sucked away, and at the same time, the metal chips remaining on the conical surface of the electromagnet can also be sucked away.

[0021] In this embodiment, a control valve 118 is installed at one end of the discharging pipe 115 close to the discharge port 112.

[0022] In this embodiment, the large-diameter end of the iron removal pipe body 109 is connected to the cotton conveying pipeline 101 through a first pipe joint 119. The air inlet end of the cotton conveying fan 102 is connected to an input pipe 120, and the input pipe 120 is connected to the small-diameter end of the iron removal pipe body 109 through a second pipe joint 121.

[0023] In this embodiment, a water storage tank 105 is provided at the top of the cotton grabbing arm 122 of the reciprocating cotton grabber 100. The left and right sides of the water storage tank 105 are connected with water outlet pipes 106, and the two water outlet pipes 106 are respectively communicated with the spray pipes 107 arranged on the left and right sides of the cotton grabbing arm 122. A plurality of atomizing nozzles 108 with downward spray ports are uniformly arranged on the spray pipes 107 along the axial direction thereof. By arranging spray pipes on both sides of the cotton grabbing arm to spray mist water on the cotton bale, the cotton bale can be wetted before cotton grabbing.

[0024] If the present utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (such as using bolts or screws for connection), or can also be understood as: a non-detachable fixed connection (such as riveting or welding). Of course, the mutual fixed connection can also be replaced by an integral structure (such as being integrally formed by using a casting process) (except when it is obviously impossible to adopt the integral forming process).

[0025] In addition, unless otherwise stated, the terms used to represent positional relationships or shapes in any of the above-disclosed technical solutions of the present utility model include states or shapes that are approximate, similar, or close thereto.

[0026] Any component provided by the present utility model can either be assembled from a plurality of individual components or be a single component manufactured by an integral forming process.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them; although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present utility model or perform equivalent replacements on some technical features; without departing from the spirit of the technical solutions of the present utility model, they should all be covered within the scope of the technical solutions claimed by the present utility model.
