Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of poultry slaughtering and processing equipment, and in particular to a transmission mechanism for a poultry plucking machine in which the working shafts are arranged in adjacent arcs based on the principle of concentric circles. Background Technology
[0002] The working shaft type poultry plucking machine is a key piece of equipment in modern poultry processing for removing feathers. Its core function is to pluck feathers through the relative motion between multiple working shafts. Different solutions exist in existing technologies for achieving multi-axis drive. A common and simple solution is to use multiple motors, for example, configuring an independent drive motor for each or each pair of working shafts. While this solution has a simple transmission structure, it has significant drawbacks: First, using multiple motors increases manufacturing costs, equipment weight, and energy consumption; second, it is difficult to precisely guarantee a synchronous and stable speed relationship between all working shafts, and it cannot naturally achieve strict and stable reverse rotation between adjacent shafts, which is precisely the key to generating efficient plucking force. Another solution uses a single motor, but its gear transmission layout is not optimized, resulting in a less compact structure or the inability to form a comprehensive, dead-angle-free, efficient plucking area.
[0003] Therefore, there is an urgent need in this field for a transmission solution that can overcome the disadvantages of high cost and poor coordination of multi-motor systems, and through ingenious mechanical design, drive all working axes with a single power source, and ensure that they form a stable and efficient reverse rotation working mode that can cover a wide and unobstructed area. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned defects of the existing linear shaft system layout and provide a transmission mechanism for a poultry plucking machine that features uniform force in the working area, a large effective working area, no dead corners in plucking, and high overall efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A transmission mechanism for a poultry plucking machine includes a motor D, a main shaft A driven by the motor, and multiple working shafts for plucking poultry feathers. Its core improvement lies in the inclusion of a transmission component fixing box 2. This box has lower bearing fixing positions 21 and upper bearing fixing positions 22 for mounting and fixing each working shaft, with their positioning points distributed on the circumference of a circle centered at the intersection of the axes of each working shaft. This specific design ensures that all working shafts are arranged adjacently in an arc shape in a two-dimensional plane projection perpendicular to their axes, and that the extension lines of the axes of all working shafts converge at a common center.
[0006] Each working shaft is equipped with a gear F. The meshing relationship of all gears is specially configured to form a power transmission network, ensuring that during transmission, any two adjacent working shafts on the circumference always rotate in opposite directions, thereby generating an effective coiling force at any adjacent position in the circular working area.
[0007] As a preferred embodiment of this utility model, the working shaft specifically includes a driven shaft A1, a right transition shaft B, a right transition driven shaft B1, a left transition shaft C, and a left transition driven shaft C1. The gear meshing path is as follows: the gear of the main shaft A meshes simultaneously with the gears of the driven shaft A1 and the left transition shaft C; the gear of the driven shaft A1 meshes with the gear of the right transition shaft B; the gear of the left transition shaft C meshes with the gear of the left transition driven shaft C1; and the gear of the right transition shaft B meshes with the gear of the right transition driven shaft B1. This arrangement forms multiple sets of cooperating, counter-rotating shaft pairs on a circular array.
[0008] Each working shaft is precisely mounted in its corresponding fixing position in the transmission component fixing box 2 via the lower bearing E and the upper bearing G, ensuring the geometric accuracy and operational stability of the concentric arc array. The decorative cap H is also installed via the decorative cap fixing position 23 provided on the transmission component fixing box 2. Finally, the transmission component fixing box 2 is connected and combined with a handle 1 to form the outer shell assembly of the transmission mechanism.
[0009] The beneficial effects of this utility model are as follows: Uniform and seamless operation: The arc-shaped array layout based on the concentric circle principle fundamentally eliminates the "weak areas at both ends" problem of linear layouts. The plucking force is evenly distributed radially throughout the entire circular working area, with no obvious efficiency attenuation areas, ensuring the consistency of plucking effect across all areas of the poultry's body surface and effectively avoiding regional omissions.
[0010] Space utilization and fit optimization: This layout concentrates the effective working area in the center of the equipment, resulting in higher space utilization efficiency for the same equipment end-face projection area. At the same time, the convergent arrangement is more conducive to fitting the spherical contours of the bird's body.
[0011] Smooth and efficient transmission: The optimized gear meshing path is adapted to the circular layout, the transmission chain is short, the power transmission is direct, the efficiency is high, the operation is smooth, and the vibration and noise are low.
[0012] Protecting the bird's body: The counter-rotation of adjacent axes generates a twisting force on the feathers, rather than a one-way hard pull, which can effectively reduce damage to the bird's skin during efficient feather plucking. Attached Figure Description

[0017] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0018] like Figure 1-4 As shown, when assembling this utility model, firstly, each working shaft, including the main shaft A, driven shaft A1, right transition shaft B, right transition driven shaft B1, left transition shaft C, and left transition driven shaft C1, is sequentially fitted with upper and lower end bearings E, gears F, upper end bearing G, and decorative cap H. Then, the assembled shaft system is aligned and pressed into the corresponding lower bearing fixing positions 21 and upper bearing fixing positions 22 of the transmission component fixing box 2. The positioning points of these fixing positions are distributed on the circumference of a circle centered on the intersection of the axes of each working shaft, ultimately forming an arc-shaped array where all working shafts converge at a common center. During this process, it is essential to ensure that all gears F mesh correctly according to the predetermined meshing relationship. After connecting the output shaft of the motor D to the main shaft A, finally, the handle 1 is fastened to the transmission component fixing box 2, thus completing the assembly of the entire machine.
[0019] During operation, motor D is started, and power is transmitted to the entire gear system via spindle A. All working shafts are arranged in a concentric arc array, ensuring that any two adjacent shafts on the circumference rotate in opposite directions. When the poultry part to be plucked is placed in this working area, its surface can fully and evenly contact the multiple working shafts, and the feathers are efficiently and consistently rolled in and plucked without any missed areas, achieving high-quality and high-efficiency feather removal.
