Description

Technical Field

[0001] This utility model relates to supporting equipment in the field of bulk grain storage, and in particular to a bulk grain unloading device. Background Technology

[0002] When unloading bulk grain from a flat warehouse, the required unloading equipment is needed; this equipment is also known as an unloading robot.

[0003] Existing warehouse exit equipment, such as the "intelligent warehouse exit robot" disclosed in Chinese patent CN117262781A, includes a frame equipped with wheels, and a first conveying device and a second conveying device for conveying bulk grain from bottom to top on the frame, with the second conveying device located above the first conveying device.

[0004] The lower end of the first conveying device is hinged with conveying augers arranged on the left and right. An electric telescopic rod is provided between the first conveying device and the corresponding conveying auger to drive the conveying auger to rotate around its rotation axis to adjust its posture.

[0005] In operation, two conveying augers work to transport the bulk grain from the left and right sides towards the center. The grain is then conveyed from bottom to top by the first conveyor, which transfers it to the second conveyor, where it is then transported from bottom to top again. When the orientation of the conveying augers needs to be changed, the orientation can be adjusted by extending or retracting an electric telescopic rod, thus adjusting the angle between the two augers to meet various grain discharge requirements.

[0006] The problem with the existing discharge equipment is that the orientation of the conveying auger is adjusted by an electric telescopic rod. However, the rotation angle of the conveying auger around its own axis is limited due to the angle and extension stroke of the electric telescopic rod. Utility Model Content

[0007] The purpose of this utility model is to provide a bulk grain unloading device to solve the technical problem in the prior art where the adjustment of the conveying auger posture angle is limited due to the use of an electric telescopic rod to adjust the posture of the conveying auger.

[0008] The technical solution of the bulk grain unloading equipment of this utility model is as follows:

[0009] A bulk grain unloading device includes a support frame, on which a bulk grain lifting device for conveying bulk grain from bottom to top is mounted. At the bottom of the bulk grain lifting device are a left-side conveying auger and a right-side conveying auger arranged horizontally. Both the left-side and right-side conveying augers include auger housings. A left-side rotating shaft and a right-side rotating shaft with their rotation axes extending vertically are rotatably mounted at the lower end of the bulk grain lifting device. The left-side rotating shaft is connected to the right end of the auger housing of the left-side conveying auger via a left-side connecting arm, and the right-side rotating shaft is connected to the left end of the auger housing of the right-side conveying auger via a right-side connecting arm. A left-side gear is fixed to the upper end of the left-side rotating shaft, and a right-side gear that meshes with the left-side gear is fixed to the upper end of the right-side rotating shaft. A drive motor is also mounted at the bottom of the bulk grain lifting device, and a transmission gear that meshes with either the left-side or right-side gear is connected to the motor shaft of the drive motor.

[0010] Furthermore, the drive motor is vertically positioned, and the transmission gear is fixed to the motor shaft of the drive motor. The diameter of the left gear is the same as that of the right gear, but the diameter of the transmission gear is smaller than that of the right gear.

[0011] Furthermore, one end of the left connecting arm is fixed to the left rotating shaft, and the other end of the left connecting arm is connected to the left conveying auger via the left vertical shaft.

[0012] Furthermore, one end of the right connecting arm is fixed to the right rotating shaft, and the other end of the right connecting arm is connected to the right conveying auger via the right vertical shaft.

[0013] Furthermore, the left end of the auger housing of the left-side conveying auger is rotatably fitted with a left-side support roller for rolling contact with the ground.

[0014] Furthermore, there are two left-side support rollers, which are spaced apart.

[0015] Furthermore, the right end of the auger housing of the right-side conveying auger is rotatably fitted with a right-side support roller for rolling contact with the ground.

[0016] Furthermore, there are two right-side support rollers, which are spaced apart.

[0017] The beneficial effects of this technical solution are as follows: When the drive motor rotates forward, the left and right gears mesh and rotate synchronously, allowing the left and right conveying augers to rotate relative to each other, thus reducing the angle between them. When the drive motor rotates in the reverse direction, the left and right gears mesh and rotate synchronously, allowing the left and right conveying augers to rotate in opposite directions, thus increasing the angle between them, to adapt to various working conditions. In this invention, only one drive motor is needed to adjust the posture of the left and right conveying augers, reducing the number of drive components required. Moreover, since the posture adjustment of the conveying augers is achieved through gear rotation, compared to the prior art that uses an electric telescopic rod to adjust the posture, the adjustable range of the angle between the two conveying augers is much wider.

[0018] Furthermore, the addition of left and right support rollers makes it easier to adjust the posture of the left and right conveying augers. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0025] A specific embodiment of a bulk grain unloading device of this utility model is as follows: Figures 1-3 As shown,

[0026] The device includes a support frame with wheels (not shown in the figure) and a bulk grain lifting device 6 for conveying bulk grain from bottom to top. In this embodiment, the bulk grain lifting device is a scraper conveyor 16. At the bottom of the bulk grain lifting device are a left-side conveying auger 20 and a right-side conveying auger 12 arranged horizontally. Both the left-side and right-side conveying augers include auger housings, with the grain-facing side of the auger housing being open. During use, the bulk grain can enter the corresponding conveying auger through the open opening. The left-side conveying auger 20 conveys the bulk grain from left to right to the bottom inlet of the bulk grain lifting device, and the right-side conveying auger 12 conveys the bulk grain from right to left to the bottom inlet of the bulk grain lifting device.

[0027] In the figure, item 17 represents the auger housing of the left conveying auger, item 15 represents the auger housing of the right conveying auger; item 19 represents the left auger motor installed on the auger housing of the left conveying auger, item 13 represents the right auger motor installed on the auger housing of the right conveying auger, the left auger motor 19 is driven to the auger shaft of the left conveying auger, and the right auger motor 13 is driven to the auger shaft of the right conveying auger.

[0028] All of the above are existing technologies and will not be described in detail here.

[0029] The lower end of the bulk grain lifting device 6 is rotatably equipped with a left rotating shaft 4 and a right rotating shaft 9 whose rotating axes extend in the vertical direction. The left rotating shaft 4 is connected to the right end of the auger housing of the left conveying auger through the left connecting arm 3, and the right rotating shaft 9 is connected to the left end of the auger housing of the right conveying auger through the right connecting arm 10.

[0030] Specifically, the right end of the left connecting arm 3 is fixed to the left rotating shaft 4, and the other end of the left connecting arm 3 is fixed to the left vertical shaft 2. The bottom of the left vertical shaft 2 is fixedly connected to the auger housing 17 of the left conveying auger. The left end of the right connecting arm 10 is fixed to the right rotating shaft 9, and the other end of the right connecting arm 10 is fixed to the right vertical shaft 11. The bottom of the right vertical shaft 11 is fixedly connected to the auger housing 15 of the right conveying auger.

[0031] A left gear 5 is fixed at the upper end of the left rotating shaft 2, and a right gear 8 that meshes with the left gear is fixed at the upper end of the right rotating shaft 9. A drive motor 7 is also provided at the bottom of the bulk grain lifting device. A transmission gear 21 that meshes with the right gear 8 (or the left gear) is connected to the motor shaft of the drive motor 7.

[0032] In this embodiment, the drive motor 7 is arranged vertically, and the transmission gear 21 is fixed on the motor shaft of the drive motor. The diameter of the left gear 5 is the same as the diameter of the right gear 8, and the diameter of the transmission gear 21 is smaller than the diameter of the right gear.

[0033] The left end of the auger housing of the left conveying auger is rotatably equipped with a left support roller 18 for rolling contact with the ground. There are two left support rollers 18, which are spaced apart from each other.

[0034] The right end of the auger housing of the right-side conveying auger is rotatably equipped with a right-side support roller 14 for rolling contact with the ground. There are two right-side support rollers 14, which are spaced apart from each other.

[0035] In use, the bulk grain on the left is conveyed from left to right by the left conveying auger to the bottom inlet of the bulk grain lifting device; the bulk grain on the right is conveyed from right to left by the right conveying auger to the bottom inlet of the bulk grain lifting device, and then lifted from bottom to top by the bulk grain lifting device.

[0036] When it is necessary to change the angle between the left and right conveying augers, the drive motor drives the transmission gear to rotate, which in turn drives the right gear to rotate. The right gear meshes with the left gear, allowing the left and right conveying augers 20 and 12 to adjust their orientation around their own rotation axes. Figure 3 As shown, the setting of the left support roller 18 and the right support roller 14 makes the posture adjustment of the left and right conveying augers smoother. In addition, it also avoids the support at both ends of the left and right conveying augers, thus avoiding the problem of single-end force concentration caused by the cantilever structure.
