Description

Technical Field

[0001] This utility model relates to the field of poultry defecation machine technology, specifically to a defecation device with a low defect rate. Background Technology

[0002] Defeathering machines are used to remove feathers from slaughtered poultry such as chickens, ducks, and geese, significantly improving defeathering efficiency. Current defeathering machines utilize multiple defeathering rods inside a drum, achieving defeathering through friction between the rods and the slaughtered poultry. For example, Chinese patent document CN220343465U describes a defeathering device for chicken slaughter, including a defeathering machine and a movable shaft. Multiple fixed and movable rings are fixedly installed inside the defeathering machine, staggered. Multiple rubber rods are fixedly installed on the inner walls of both the fixed and movable rings. The rotation of the rubber rods on the movable rings, limited by the rubber rods on the fixed rings, achieves defeathering of the chicken. However, current defeathering machines, by placing the slaughtered poultry in the same position within the defeathering drum and continuously rotating it, do not adequately vary the contact area between the poultry and the defeathering rods, resulting in some feather residue that requires manual removal. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0027] In one embodiment, a low-residue hair removal device is provided, such as... Figure 1 As shown, the low-defect-rate depilation equipment includes a body 10, which includes a frame and an outer skin. The body 10 is provided with a depilation chamber 11, which is a cavity used for depilating poultry.

[0028] Multiple hair removal chambers 11 are provided with such Figure 4and Figure 5 The depilatory rollers 20 shown have multiple rows of depilatory rubber rods 21 on each roller. The depilatory rubber rods 21 are made of rubber and are threaded rods. The main body of the depilatory rubber rods 21 has dense annular grooves on its outer circumference. The depilatory rollers 20 form a poultry transfer channel 30. Multiple poultry transfer levers 40 are arranged along the poultry transfer channel 30. Under the push of the poultry transfer levers 40, the poultry to be depilated moves along the poultry transfer channel 30. During the movement, the depilatory rollers 20 depilate the poultry.

[0029] The machine body 10 also includes a power device 50 for rotating each defecation roller 20 and poultry transfer lever 40. The machine body 10 has a poultry inlet 12, a poultry outlet 13, and a feather outlet 14. The poultry inlet 12 is located at the front end of the poultry transfer channel 30, the poultry outlet 13 is located at the rear end of the poultry transfer channel 30, and the feather outlet 14 is located at the bottom of the defecation chamber 11. Figure 1 As shown, the poultry inlet 13 is a feeding hopper located on the front side of the machine body, and the poultry outlet 13 is equipped with an outer cover, such as... Figure 2 As shown, an inclined plate 15 is provided at the bottom of the hair removal chamber 11 in the body 10. The end of the inclined plate 15 is located at the lower edge of the hair outlet 14, and the removed hair slides along the inclined plate 15 to the hair outlet 14.

[0030] The low-residue-rate defecation equipment operates as follows: The power unit 50 is started, and the equipment begins to run. Poultry, scalded with hot water, is placed into the defecation chamber 11 through the poultry inlet 12. Driven by the poultry transfer lever 40, the poultry to be defecate moves along the poultry transfer channel 30. During this movement, the defecation rollers 20 process the feathers. Figure 6 As shown, the depilatory rubber rod 21 on the depilatory roller 20 is a spiral rod that can rub and scrape the feathers of poultry, causing the feathers to fall off the poultry. The depilated poultry is discharged from the poultry discharge outlet 13, and the removed feathers are discharged from the feather outlet 14.

[0031] During the poultry removal process, the poultry to be removed is moved along the poultry removal channel 30 by the poultry transfer lever 40. The poultry does not stay in the same position. During the movement, the poultry constantly changes its posture, so that all parts of the poultry can fully contact the removal stick, thereby achieving full removal of the poultry and a low defect rate after processing.

[0032] Furthermore, such as Figure 2As shown, the depilatory rollers are arranged in four sets, including a first depilatory roller 20-1, a second depilatory roller 20-2, a third depilatory roller 20-3, and a fourth depilatory roller 20-4 arranged in parallel. The first depilatory roller 20-1, the second depilatory roller 20-2, and the third depilatory roller 20-3 are located on the upper, rear, and lower sides of the poultry transfer channel 30, respectively, and the fourth depilatory roller 20-4 is located in front of the third depilatory roller 20-3. All four sets of depilatory rollers are arranged horizontally. The first depilatory roller 20-1, the second depilatory roller 20-2, the third depilatory roller 20-3, and the fourth depilatory roller 20-4 are responsible for depilating the poultry on the upper, rear, and lower sides of the poultry transfer channel 30, respectively. The fourth depilatory roller 20-4 is responsible for depilating the poultry on the bottom front side and also prevents the poultry from falling out of the poultry transfer channel 30 from the bottom.

[0033] Furthermore, such as Figure 2 As shown, the sum of the lengths of the depilatory rubber sticks on adjacent depilatory rollers is greater than the distance between the surfaces of the adjacent depilatory rollers. This ensures that the space between adjacent depilatory rollers is swept by the depilatory rubber sticks during the rotation of the depilatory rollers, allowing the poultry feathers to fully contact the depilatory rubber sticks. The depilatory rubber sticks on adjacent depilatory rollers are staggered axially or circumferentially to avoid collisions between the depilatory rubber sticks on adjacent depilatory rollers during the rotation of the depilatory rollers.

[0034] Furthermore, such as Figure 7 As shown, the poultry transfer lever 40 includes a vertical shaft 41, which is driven to rotate by a power device 50. A crossbar 42 is provided at the lower part of the vertical shaft 41. Each set of poultry transfer levers 40 has two crossbars, one short and one long, and the crossbars 42 on adjacent poultry transfer levers 40 are vertically staggered to avoid collisions. The crossbar 42 includes a sleeve 421 fixed to the vertical shaft 41. Rubber rods 422 are provided at both ends of the sleeve 421. The poultry is moved by the rubber rods 422, avoiding hard contact with the poultry and thus preventing damage to the poultry's skin.

[0035] Furthermore, such as Figure 3As shown, the power unit 50 includes a motor 51 mounted on the machine body. The motor 51 is sequentially driven and connected to each plucking stick and each poultry transfer lever 40 through a transmission mechanism. The transmission mechanism includes chain drive components arranged between adjacent plucking sticks and between adjacent poultry transfer levers, and a gearbox arranged between the plucking sticks and the poultry transfer levers. The first depilatory roller 20-1, the second depilatory roller 20-2, the third depilatory roller 20-3, and the fourth depilatory roller 20-4 are all mounted on the machine body 10 via bearing seats. Each poultry transfer lever 40 has a bearing seat 43 at its top. The motor 51 is connected to the fourth depilatory roller 20-4 via a belt drive mechanism. Chain drive components are provided between the fourth depilatory roller 20-4 and the third depilatory roller 20-3, the second depilatory roller 20-2, and the first depilatory roller 20-1, as well as between adjacent poultry transfer levers 40. A gearbox 52 is also provided on the machine body 10. The first depilatory roller 20-1 is connected to the first poultry transfer lever 40 via the chain drive components and the gearbox 52, realizing the overall transmission of each moving part.
