Description

The invention relates to the field of mechanical engineering for the food industry, in particular to devices for processing poultry processing products (poultry carcasses, their parts or internal organs), and can be used in the poultry industry in poultry processing lines, including quails.

Known devices for cooling (washing) poultry carcasses, their parts or internal organs (heart, muscle stomach, liver), consisting of a housing, a drive and a screw, at the output end of which a loading plate (grill) is rigidly installed, replacing the last quarter of the last turn of the screw (see prospectus of STORK, Netherlands, exhibition Agroprodmash-2013).

The auger body is filled with ice water (when cooling the product) or tap water (when washing the product). On the drive side of the device, a product (bird carcasses, parts or internal organs) is supplied with water to its body. Depending on the required cooling (washing) time, productivity and type of product, the device has the corresponding dimensions of the screw turn, the pitch of the coil, the length of the screw (housing) and the speed of rotation of the screw. Moving turns of the screw through the device, the product is unloaded from the device with a special plate (grill) that replaces the last quarter of the last turn of the screw.

The disadvantage of these devices is the incomplete unloading of the product from the body with water: part of the product slides back from the discharge plate (grill) into the body with water, while the screw turns continue to continuously supply a new product to the unloading place, as a result of which excess product accumulates at the outlet , which is unloaded from the housing only after some time after the termination of the supply of the product to the input of the device. In addition to increasing the operating time of the device, the product itself is located at an uneven time in the device, because during unloading, the same carcass (part of the carcass or internal organs) can repeatedly slide off the platinum (lattice). Excessive presence of the product in water reduces its quality.

The closest technical solution is a device for cooling (washing) internal organs, consisting of a housing, a drive and an auger, at the output end of which two discharge plates (gratings) are rigidly mounted, one of which replaces the last quarter of the last turn of the screw, and the second is offset relative to the first 180 degrees (see Fig. 1 of the prospectus of STORK, Netherlands, Agroprodmash-2013 exhibition).

The disadvantage of this device is also the incomplete unloading of the product from the body with water: part of the product slides back from the discharge plate (grill) into the body with water, while the turns of the screw continue to continuously supply a new product to the unloading place, resulting in excess a product that is unloaded from the housing only some time after the supply of the product to the input of the device stops. The second unloading plate (grill) only reduces the unloading time by a certain amount, but does not eliminate the possibility of repeated slipping of the same carcass (part of the carcass or internal organs) from the unloading plate (grill), because the slipped product is not captured by the second discharge plate (grate), located on its back side. Thus, this device reduces, but does not completely eliminate the possibility of a prolonged stay of the product in water, which reduces its quality.

The technical task of the present invention is to improve the quality of products and reduce to a minimum the operating time of the device after the cessation of product supply.

The solution to the technical problem is achieved by the fact that in the device containing the housing, the drive and the auger, at the output end of which two unloading plates (grids) are rigidly mounted, one of which replaces the last quarter of the last turn of the auger, and the second is displaced relative to the first by 180 degrees, unloading the plate (lattice) is mounted at the end of the screw with the possibility of rotation relative to the screw and is connected with the output end of the screw by a two-stage accelerating gear transmission.

The technical result is achieved by the fact that in the proposed device the unloading plate (grill) is mounted on the end of the screw with the possibility of rotation relative to the screw and is rotated using a two-stage accelerating gear from the output end of the screw, which allows the unloading plate (grill) to make several revolutions in one auger turnover and thereby ensure complete unloading of the product in a minimum time without losing its quality.

Comparative analysis with the prototype shows that the inventive device differs in the way of connecting the unloading plate (grill) with the output end of the screw and the presence of an additional element (two-stage accelerating gear transmission) connecting the output end of the screw with the unloading plate (grill), which allows performing one revolution of the screw several revolutions (depending on the gear ratio of the two-stage accelerating gear) of the discharge plate (lattice) relative to the screw and ensure that th complete discharge of the product in a minimum of time without losing its quality.

Thus, the claimed device meets the criterion of "novelty."

Comparison of the proposed solution not only with the prototype, but also with other technical solutions did not reveal signs that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "significant differences".

The technical solution is illustrated by drawings.

Figure 1 shows three projections of the device.

Figure 2 shows the leader A - a two-stage accelerating gear transmission connecting the end of the screw with the unloading plate (grill).

The device consists of a housing 1, a drive 2, a screw 3 and an unloading plate (grill) 4 and a two-stage accelerating gear 5. The plate (grill) 4 has a shank 6, which, with its bushings 7, is seated on the end “a” of the screw 3 and is simultaneously inserted into the sleeve 8 of the support 9 mounted on the housing 1. At the end of the shank 6 on the key 10, a small gear 11 is installed, and on the end “a” of the screw 3 on the key 10, a large gear 12 is installed. On the axis 13 mounted on the housing 1, a two-gear gear 14, the small crown of which "b" is engaged with a large gear 12, and the large crown “c” - meshing with the small gear 11. The number of teeth Z1 of the large gear 12 is equal to the number of teeth of the large ring “c”, and the number of teeth Z2 of the small gear 11 is equal to the number of teeth of the small ring “b” . The large gear 12 and the small crown “b” form the first stage of the accelerating gear 5, and the large ring “c” and the small gear 11 form the second stage. At the output of the device on the housing 1 has a receiving tray 15.

The device operates as follows.

The drive 2 rotates the screw 3, which with its turns moves the processed product (carcasses, their parts or internal organs) in the case 1 filled with water to the device outlet, where the unloading plate (grill) 4 captures the product and unloads it on the receiving tray 15.

Moreover, the large gear 12 mounted at the end “a” of the screw 3 transmits rotation through the two-gear gear 14, which rotates freely on the axis 13, to the small gear 11 and, therefore, through the shank 6 to the unloading plate (grill) 4. Since gear ratios from the big gear 12 to the small gear “b” (first gear stage) and from the big gear “c” to the small gear 11 (second gear) are equal and less than one, then the unloading plate (grill) 4 will rotate faster than the screw 3 For example, with Z1 = 30 and Z2 = 15, the total gear ratio will be 0.25, i.e. for one revolution of the screw 3, the unloading plate (grill) will make 4 turns, and with Z1 = 32 and Z2 = 18 the total gear ratio will be 0.316 and for one revolution of the screw 3 the plate (grill) 4 will make 3.16 turns.

Depending on the required cooling (washing) time, productivity and type of product, the required gear ratio is selected and thus provide quick discharge of the cooled (washed) product.

Thus, the installation of the unloading plate (grill) at the end of the screw with the possibility of rotation relative to the screw using a two-stage accelerating gear transmission allows the unloading plate (grill) to make several revolutions in one revolution of the screw and thereby ensure complete unloading of the product in a minimum time without losing its quality .
