[0023] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0024] The technical solution of the utility model is further described below in conjunction with the accompanying drawings. Figure 1-4 The present invention shows a cotton picking head translation device for a cotton picker, comprising: a picking head bracket 1, a rack 2, a gear 3, a first roller 5 and a second roller 8. The device adopts a gear and rack transmission structure, wherein the gear 2 is fixed to a gear bracket 4, and the gear bracket 4 is directly or indirectly fixed to a cotton picking head 7. When the gear 2 rotates, the cotton picking head 7 moves left and right, and the rack 2 is fixed to the picking head bracket 1. The device can be applied to various machine models and various row spacings.

[0025] The existing picking head bracket 1 includes two parallel beams, which are consistent with the translation direction of the cotton picking head 7. Both ends of the two beams are connected with corresponding guard plates. The two beams are arranged on both sides of the cotton picking head 7. A bracket is provided on the cotton picking head 7 for fixing and installing rollers. When the cotton picking head 7 moves left and right, the beam not only supports the rollers, but also guides and limits the rolling of the rollers, playing the role of tracks. The above-mentioned rollers are in contact with the tracks and are prone to slipping.

[0026] As an embodiment of the present utility model, Figure 1 The picking head bracket 1 includes a first crossbeam 101, a guide rail 102 and a second crossbeam 103 arranged in parallel. The rack 2 is arranged on the first crossbeam 101, and the rack 2 is meshed with the gear 3. The gear 3 is fixed to one end of the gear bracket 4 through the wheel axle 9 and the shaft seat; the first roller 5 is matched with the guide rail 102, and the first roller 5 is fixed to one end of the roller bracket 6 through the wheel axle 9 and the shaft seat, and the other end of the gear bracket 4 is fixed to the middle of the roller bracket 6, and the other end of the roller bracket 6 is fixedly connected to one side wall of the cotton picking head 7; the second roller 8 can roll on the second crossbeam 103, and the second roller 8 is fixed to the other side wall of the cotton picking head 7 through the wheel axle 9 and the shaft seat. By comparing the existing picking head hanger with the improved picking head hanger of the utility model, it is found that guide rails and racks are added to the picking head hanger, and a gear is indirectly connected to the cotton picking head. The gear and rack are meshed to drive the gear to rotate, so that the cotton picking head is more stable when it is translated on the picking head hanger, and it is not easy to slip. It is light and reliable to move, which is conducive to maintenance operations.

[0027] In order to make the cotton picking head 7 more stable when translated, for each cotton picking head 7 , the number of the first rollers 5 is set to two, which form three-point support with the second rollers 8 on each supporting surface of the picking head hanger 1 .

[0028] After several cotton picking heads 7 are arranged into a group, the position of the rack 2 is set to adapt to the corresponding fixed roller bracket 6, so that when the cotton picking heads 7 are translated left and right on the guide rail 102, the gear bracket 4 fixed on the roller bracket 6 is translated left and right, and the gear 3 can be meshed with the tooth groove of the rack 2. A plurality of gears are arranged under the rack 2, preferably 1-3 gears, so that the meshing effect is better, and it is less likely to slip between the first roller 5 and the guide rail 102. In order to maintain the meshing effect, under the requirement of minimizing the material used for the gears, the following operation method can be used to construct: for one group of cotton picking heads 7 arranged at intervals, the number of gears 3 is set to two, and the rack 2 is meshed with two gears 3 at the same time; for the remaining group of cotton picking heads 7 arranged at intervals, the number of corresponding gears 3 is set to one, and the rack 2 is meshed with one gear 3 at the same time.

[0029] In order to reduce vibration during the translation of the cotton picking head 7 , the tread of the second roller 8 may be configured to be an elastic product structure, such as rubber, which is wrapped on the tread of the second roller 8 .

[0030] How this utility works:

[0031] like Figure 1 , the cotton picking head 7 is hung on the picking head bracket 1. When the cotton picking head 7 needs to be moved for maintenance, a spanner is used to manually drive the outside of the wheel shaft 9, and the gear 3 rotates on the rack 2, thereby driving the first roller 5 to move on the guide rail 102, so that the cotton picking head 7 as a whole moves left and right on the picking head bracket 1 following the rotation rhythm of the wheel shaft 9.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
