[0014] The following are specific embodiments of the utility model, and the technical solutions of the utility model are further described in conjunction with the accompanying drawings. However, the utility model is not limited to these embodiments. It should be noted that the front-back, left-right and other positional relationships in the utility model are described with reference to the attached Figure 1 drawings.

[0015] As Figure 1 and 2 shown, the utility model provides a tail wheel adjusting mechanism for an automatic egg picking machine, which includes a tail wheel frame 1, a rotating shaft 2, a tail wheel 3 and a brush 4. The tail wheel frame 1 is of a U-shaped structure, and chutes 5 with openings facing forward are provided on both sides of the tail wheel frame 1, which can facilitate the installation of the egg collecting belt on the tail wheel 3. The two ends of the rotating shaft 2 are slidably installed in the chutes 5, the tail wheel 3 is rotatably installed on the rotating shaft 2, and lead screws 6 are connected to the two ends of the rotating shaft 2 passing through the chutes 5. The brush 4 is arranged in the tail wheel frame 1 and is located below the tail wheel 3.

[0016] As Figure 1As shown in the figure, the egg collecting belt is located on the tail wheel 3, and the brush 4 is located directly below the egg collecting belt. During the operation of the egg collecting belt, the brush 4 constantly cleans the dust or impurities attached to the egg collecting belt to avoid affecting subsequent use; the tail wheel 3 rotates on the rotating shaft 2 as the egg collecting belt moves. When adjusting the tension of the egg collecting belt, the positions of both ends of the rotating shaft 2 in the sliding groove 5 can be adjusted through the lead screws 6 at both ends of the rotating shaft 2, changing the position of the tail wheel 3, thereby adjusting the tension of the egg collecting belt; when the egg collecting belt runs off track, only one of the two lead screws 6 needs to be adjusted accordingly to adjust the deviation of the egg collecting belt. In the present utility model, when the egg collecting belt on the tail wheel 3 at the tail runs off track, it indicates that the egg collecting belt on that side is relatively loose. By adjusting the tail wheel 3, the tension of the egg collecting belt on that side can be adjusted. Whether adjusting the off-track egg collecting belt or the tension of the egg collecting belt, the present utility model does not require disassembling the tail wheel 3, which brings convenience to the adjustment of the egg collecting belt and saves a large amount of maintenance man-hours.

[0017] Both sides at the rear end of the tail wheel frame 1 are provided with adjusting plates 7, and one end of the lead screw 6 far from the rotating shaft 2 passes through the adjusting plate 7 and is threadedly connected with a nut 8.

[0018] As Figure 2 shown, the lead screw 6 is limited by the nut 8 and the adjusting plate 7. When installing the egg collecting belt at the tail and the tail wheel 3, the tail wheel 3 is located between the egg collecting belts. The tail wheel 3 drives the egg collecting belt to move towards the sliding groove 5 until both ends of the rotating shaft 2 are in the sliding groove 5. The lead screw 6 passes through the adjusting plate 7 and is fixed by the nut 8; when adjusting the tension of the egg collecting belt, the position of the tail wheel 3 is adjusted by pushing and pulling the two lead screws 6, and is fixed by the nut 8 to adjust the tension of the egg collecting belt. If the egg collecting belt deflects to the left, then adjust the left lead screw 6, pull the left lead screw 6 backward, or adjust the right lead screw 6 and push the right lead screw 6 forward.

[0019] One side of the lead screw 6 is fixedly connected with a connecting ring 9, and the connecting ring 9 is sleeved on the rotating shaft 2 and limited on the rotating shaft 2 by a limit nut 10.

[0020] As Figure 1 shown, the connecting ring 9 facilitates the installation of the lead screw 6 on the rotating shaft 2, and it is limited on the rotating shaft 2 by the limit nut 10, which is convenient for installation and disassembly, and provides convenience for later maintenance and repair.

[0021] It further includes a cover plate 11 with a portal structure. The tail wheel frame 1 is arranged below the cover plate 11. Flanges 12 are provided at both ends of the top of the tail wheel frame 1, and the top of the cover plate 11 is connected to the flanges 12 by bolts 13.

[0022] As Figure 1As shown, the capping plate 11 facilitates the fixation of the tail wheel adjustment mechanism. The top of the capping plate 11 is fixed to the tail wheel frame 1 by bolts 13. During installation, the other side of the capping plate 11 is detachably connected to one side of the automatic egg collection machine by bolt members, which provides convenience for subsequent maintenance and disassembly work.

[0023] At the bottom of one side of the capping plate 11, a diversion plate 14 inclined towards the brush 4 is connected by screws. An aggregate bucket (not shown in the figure) is placed at the discharge port end of the diversion plate 14.

[0024] As Figure 1 shown, the brush 4 brushes off dust and other impurities on the egg collection belt, and the dust and other impurities brushed off will be diverted and collected along the diversion plate 14.

[0025] At the rear end of the top of the capping plate 11, a connecting plate 15 perpendicular to the top of the capping plate 11 is provided, and a number of connecting holes are opened on the connecting plate 15.

[0026] As Figure 1 shown, the installation stability of the capping plate 11 can be improved through the connecting plate 15. Specifically, the connecting plate 15 is installed at the rear end of the automatic egg collection machine by passing bolt members through the connecting holes.

[0027] Principle of use: During the operation of cleaning dust, when the egg collection belt is transmitting, the brush 4 brushes off dust and other impurities on the egg collection belt, and the dust and other impurities brushed off will be diverted and collected along the diversion plate 14 to avoid excessive accumulation of dust and other impurities, which affects the normal use of the egg collection belt.

[0028] When adjusting the deviation of the egg collection belt, only one of the lead screws 6 needs to be adjusted. For example, when the egg collection belt deviates to the left, adjust the left lead screw 6 to pull the egg collection belt on the left side of the tail wheel 3 backward to adjust the tension of the egg collection belt on the left side of the tail wheel 3, or push the lead screw 6 on the right side of the tail wheel 3 forward to adjust the tension of the egg collection belt on the right side of the tail wheel 3. Similarly, when the egg collection belt deviates to the right, adjust the right lead screw 6 to pull the egg collection belt on the right side of the tail wheel 3 backward to adjust the tension of the egg collection belt on the right side of the tail wheel 3, or push the left lead screw 6 of the tail wheel 3 forward to adjust the tension of the egg collection belt on the left side of the tail wheel 3.

[0029] When adjusting the tension of the egg collection belt, adjust the two lead screws 6 simultaneously, pull or push the tail wheel 3, and change the position of the tail wheel 3 to achieve the function of adjusting the tension of the egg collection belt.

[0030] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
