[0039] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0040] The following describes the installation bracket for the jet device, the jet device and the sorting equipment of the utility model with reference to the accompanying drawings.

[0041] like Figures 1 to 4 As shown, the utility model provides a mounting bracket for an air jet device, wherein the mounting bracket for the air jet device comprises:

[0042] The jet mounting seat 100 is used to connect with the end of the jet device 500 and is provided with a rotating shaft portion 122 extending laterally from a side away from the jet device 500;

[0043] The connecting plate 200 is arranged on the jet mounting seat 100 on the same side as the rotating shaft portion 122 and has a connecting hole 201 extending laterally;

[0044] The conveying mounting seat 300 is arranged at the outlet end of the conveying device 600 and is provided with a shaft hole and a first waist-shaped hole 321 at intervals. The shaft hole can be passed through by the shaft portion 122. The first waist-shaped hole 321 is extended on a circumference with the shaft portion 122 as the center and the distance between the shaft portion 122 and the connecting hole 201 as the radius. The conveying mounting seat 300 is detachably connected to the connecting plate 200 by a first fastener 330 passed through the connecting hole 201 and the first waist-shaped hole 321.

[0045] When the jet device 500 uses the above-mentioned mounting bracket, since it includes the jet mounting seat 100, the connecting plate 200 and the conveying mounting seat 300, the jet mounting seat 100 is connected to the end of the jet device 500, the conveying mounting seat 300 is arranged at the outlet end of the conveying device 600, and the jet mounting seat 100 is provided with a rotating shaft portion 122 and a connecting plate 200 with a connecting hole 201 on the side away from the jet device 500, and the conveying mounting seat 300 is provided with a first waist-shaped hole 321 and a rotating shaft hole for the rotating shaft portion 122 to pass through, and the first waist-shaped hole 321 is centered on the rotating shaft portion 122 and the distance between the rotating shaft portion 122 and the connecting hole 201 is a radius If the spraying effect at the position where the jet device 500 is installed is not good, the first fastener 330 can be removed first, and then the shaft portion 122 can be rotated to adjust the position (angle) of the jet device 500. While rotating the shaft portion 122, the connecting hole 201 on the connecting plate 200 can be adjusted to communicate with other positions of the first waist-shaped hole 321 until the spraying effect reaches the best. The first fastener 330 can be used to reconnect the conveying mounting seat 300 and the connecting plate 200, thereby realizing the adjustable position of the jet device 500 on the conveying device 600, which is beneficial to improving the spraying effect.

[0046] Specifically, the first fastener 330 may include a bolt, a nut and a gasket, and the bolt passes through the gasket, the first waist hole 321, the connecting hole 201 and the nut in sequence, that is, the head of the bolt, the gasket, the conveying mounting seat 300 (the second flat plate portion 320), the connecting plate 200 and the nut are stacked in sequence. Of course, the utility model is not limited to this, and other suitable fasteners that can achieve detachable connection are also possible.

[0047] In the embodiment of the utility model, the jet mounting seat 100 includes a jet mounting plate 110 and a mounting shaft 120. The jet mounting plate 110 is used to fit and connect with the end of the jet device 500, so as to ensure the stability of the connection. At the same time, the jet mounting plate 110 is laterally extended on the side away from the jet device 500 to set the mounting shaft 120. The mounting shaft 120 is sequentially provided with a connecting portion 121 and a rotating shaft portion 122 along the extending direction. The first end of the connecting plate 200 is connected to the connecting portion 121, and the second end is provided with a connecting hole 201. That is, by adding the mounting shaft 120, the coaxial setting of the rotating shaft portion 122 and the connecting plate 200 is realized, so that there is no redundant connection structure between the connecting plate 200 and the jet mounting plate 110, which is convenient for rotation adjustment and disassembly. Specifically, the connecting plate 200 and the jet mounting plate 110 are relatively parallel and spaced. Of course, the utility model is not limited to this, and the connecting plate 200 can also be set independently of the mounting shaft 120, that is, the first end of the connecting plate 200 is not connected to the connecting portion 121 of the mounting shaft 120, but is directly connected to the jet mounting plate 110. However, in order to realize the horizontal through-opening of the connecting hole 201, the connecting plate 200 needs to be set as a bent plate, one end of the bent plate is connected to the jet mounting plate 110, and the flat plate portion where the other end is located is relatively parallel to the jet mounting plate 110 and has a connecting hole 201.

[0048] In the embodiment of the utility model, the first end of the connecting plate 200 is provided with a welding hole for the connecting portion 121 to pass through, and the connecting plate 200 is welded and connected to the connecting portion 121 at the welding hole. That is, the connecting plate 200 and the connecting portion 121 of the mounting shaft 120 are non-detachably fixedly connected by welding to ensure the stability of the connection. In addition, before the connecting plate 200 is welded to the connecting portion 121, a welding hole can be firstly opened on the connecting plate 200 and the connecting plate 200 can be sleeved on the connecting portion 121 through the welding hole, thereby ensuring the reliable positioning of the welding. At the same time, the opening of the welding hole is also conducive to the positioning processing of the connecting hole 201. Specifically, the connecting portion 121 can be formed with a step for stopping the connecting plate 200 at one end close to the rotating shaft portion 122, so as to achieve accurate positioning when the connecting plate 200 is sleeved on the connecting portion 121.

[0049] In the embodiment of the utility model, the connection hole 201 is arranged obliquely above the rotating shaft portion 122 and is located on the side of the rotating shaft portion 122 facing the conveying device 600. The connection hole 201 is arranged above the rotating shaft portion 122, so that when the connecting plate 200 is connected to the conveying mounting seat 300 through the first fastener 330, an upward component force can be provided to the jet mounting seat 100 to work together with the rotating shaft portion 122 to carry the jet device 500. At the same time, the connection hole 201 is on the side of the rotating shaft portion 122 facing the conveying device 600, so that the first waist-shaped hole 321 corresponding to the connection hole 201 is also arranged on the side of the rotating shaft portion 122 facing the conveying device 600, thereby reducing the area of ​​the conveying mounting seat 300 (the second flat plate portion 320) extending to the back side of the rotating shaft portion 122. Correspondingly, the first waist-shaped hole 321 is also arranged on the conveying mounting seat 300 (the second flat plate portion 320) at an angle above the rotating shaft hole, and is located between the outlet end of the conveying device 600 and the rotating shaft hole. Specifically, when the connecting plate 200 is connected to the connecting portion 121, in order to realize the above solution, the connecting plate 200 should be arranged to extend upwardly in an inclined manner from the connecting portion 121 toward the conveying device 600, and the connecting hole 201 is opened at one end of the connecting hole 201 away from the connecting portion 121.

[0050] See also Figure 2 and Figure 3 In the embodiment of the utility model, an external thread section is formed on the rotating shaft portion 122 and a tightening nut 123 is sleeved on the side extending from the conveying mounting seat 300. That is, after the jet device 500 is adjusted in place, the rotating shaft portion 122 can be locked by tightening the nut 123 to prevent the jet device 500 from rotating due to failure of the connection between the connecting plate 200 and the conveying mounting seat 300.

[0051] like Figure 2 and Figure 4As shown, in the embodiment of the utility model, a second waist-shaped hole 111 is provided on the jet mounting seat 100, and the second waist-shaped hole 111 is used to extend along the transmission direction of the conveying device 600, and the jet mounting seat 100 is detachably connected with the jet device 500 through a second fastener 112 that penetrates the end of the jet device 500 and the second waist-shaped hole 111. That is, by adding the second waist-shaped hole 111, the installation position of the jet device 500 on the jet mounting seat 100 can also be adjusted. Since the second waist-shaped hole 111 is extended along the transmission direction of the conveying device 600, it is equivalent to adjusting the front-to-back distance between the jet device 500 and the conveying device 600, thereby expanding the position adjustment space of the jet device 500, and achieving the purpose of further improving the spraying effect. Specifically, the second waist-shaped hole 111 is opened on the jet mounting plate 110 of the jet mounting seat 100, and the number of the second waist-shaped holes 111 can be multiple, and the multiple second waist-shaped holes 111 are arranged at intervals. The jet mounting plate 110 can be a square plate that matches the end shape of the jet device 500. The number of the second waist-shaped holes 111 is four, and the four second waist-shaped holes 111 are arranged at four corners of the square plate. Correspondingly, four first threaded holes are opened at the end of the jet device 500, and the second fastener 112 includes a screw and a gasket. The screw passes through the gasket and the second waist-shaped hole 111 in turn and extends into the first threaded hole for threaded connection.

[0052] In the embodiment of the utility model, the conveying mounting seat 300 is provided with a third waist-shaped hole 311, and the third waist-shaped hole 311 is used to extend along the height direction of the conveying device 600, and the conveying mounting seat 300 is detachably connected with the conveying device 600 through the third fastener penetrating the outlet end of the conveying device 600 and the third waist-shaped hole 311. That is, by adding the third waist-shaped hole 311, the installation position of the conveying mounting seat 300 on the conveying mounting seat 300 can also be adjusted. Since the third waist-shaped hole 311 is extended along the height direction of the conveying device 600, it is equivalent to adjusting the upper and lower installation heights of the jet device 500 on the conveying device 600, so that the position adjustment space of the jet device 500 can be expanded, so as to further improve the spraying effect. Specifically, the number of the third waist-shaped holes 311 can be at least two, and at least two third waist-shaped holes 311 are arranged at intervals on the conveying mounting seat 300. Accordingly, at least two second threaded holes are provided at the outlet end of the conveying device 600 for the third fastener to be tightened and connected.

[0053] Please see again Figures 2 to 4In the embodiment of the utility model, the conveying mounting seat 300 includes a first flat plate portion 310 and a second flat plate portion 320, and a third waist-shaped hole 311 is provided on the first flat plate portion 310, that is, the first flat plate portion 310 is used to be connected with the outlet end of the conveying device 600 so that the upper and lower mounting positions can be adjusted. It should be particularly noted that the outlet end of the conveying device 600 has a mounting plane 601 arranged outward, and the second threaded hole can be provided on the mounting plane 601. The first flat plate portion 310 can be arranged in close contact with the mounting plane 601 when connected, and the second flat plate portion 320 is bent and extended from the first flat plate portion 310 in a direction away from the conveying device 600 and has a rotating shaft hole and a first waist-shaped hole 321. That is, the conveying mounting seat 300 can also be set as a bent plate to be in close contact with the outlet end of the conveying device 600 in one direction and in close contact with the connecting plate 200 in another direction. Specifically, there are two third waist-shaped holes 311, and the two second waist-shaped holes 111 are spaced apart along the height extension direction of the first flat plate portion 310. Correspondingly, two second threaded holes are opened on the mounting plane 601 of the conveying device 600. The third fastener includes a screw and a gasket. The screw passes through the gasket and the third waist-shaped hole 311 in turn and extends into the second threaded hole for threaded connection.

[0054] See also Figure 2 In the embodiment of the utility model, the mounting bracket for the jet device further includes a support seat 400, which includes a fixing plate 401 and a support member 402. The fixing plate 401 is provided at the outlet end of the conveying device 600 and is located below the conveying mounting seat 300. The support member 402 is movably provided on the fixing plate 401 and is used to support the conveying mounting seat 300. The addition of the support seat 400 allows a supporting force to be applied to the conveying mounting seat 300 during the process of adjusting the position of the conveying mounting seat 300, thereby preventing the entire device from sliding down rapidly due to the loosening of the third fastener. Specifically, the fixing plate 401 is provided with an adjustment threaded hole that is set up and down, and the support member 402 can be provided to include a bolt and a mounting nut. The bolt is set through the adjustment threaded hole, and the upper end is used to abut against the lower end of the conveying mounting seat 300 to support the conveying mounting seat 300. The height of the bolt can be adjusted by turning the bolt to adapt to the height adjustment of the conveying mounting seat 300. After the position of the bolt is adjusted to the right position, the mounting nut set on the bolt can be tightened to play the role of fixing the bolt. Of course, the utility model is not limited to this, and other liftable structures are also possible, for example: the support member 402 moves up and down on the fixing plate 401, and is fixedly connected by selecting holes at different positions on the fixing plate 401.
