Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and in particular relates to a feed crushing and mixing device for crayfish breeding. Background Art

[0002] Feed is a general term for food for animals raised by humans. In a narrower sense, general feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten types of feed raw materials, such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, additives, whey powder, oil, meat and bone meal, grains, sweet sorghum, etc. In the process of feed processing and production, it is often necessary to crush and mix a variety of raw materials. In the existing technology, the crushing and mixing processes are separate operations. The crushing process selects corresponding equipment according to different classifications. After the crushing is completed, the material needs to be transported to the mixing equipment manually or by forced auger. The crushed material needs to be weighed according to the formula requirements, and then poured into the mixing equipment for mixing and tempering.

[0003] Chinese patent CN208612310U discloses a feed crushing and mixing device, including a drum and a fixed support frame, a feed port is provided at one end of the drum, and a discharge port is provided at the other end, the drum is installed on the fixed support frame through the feed port and the discharge port, the outer wall of the drum is provided with a rotating drive motor and a rotating support seat driven by a gear ring, the inner wall of the drum is provided with a spirally distributed guide plate, the guide plate is in an arc shape, two pressure rollers with opposite rotation directions are provided in the drum, the pressure rollers are connected to the inner wall of the drum through a support member, and one end of the pressure rollers is connected to the crushing drive motor through a gear.

[0004] In combination with the above scheme, in actual application, since the raw materials of lobster feed are large in volume and cannot be eaten directly, and since a single feed cannot meet the nutritional requirements of lobster farming, it is necessary to mix the main raw materials with other added nutrients and feed the lobsters after mixing. However, the crushing knives of traditional mixing crushers are all of a single type, and the degree of crushing of the raw materials is only achieved by regulating the speed and driving time of the driving system, and its efficiency is low.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0010] Furthermore, a lower cutter disc is fixedly mounted on the rotating shaft, and the lower cutter disc is located below the upper cutter disc, and a plurality of blades are fixedly mounted on the upper surface of the lower cutter disc.

[0011] Furthermore, the blades are divided into inner ring blades and outer ring blades, the inner ring blades are irregularly distributed inside the upper surface of the lower blade disc, and the outer ring blades are evenly distributed outside the upper surface of the lower blade disc.

[0012] Furthermore, the upper cutter disc includes a bottom plate and a top plate, the bottom plate and the top plate are fixedly connected via a support column, and a hemispherical shell is fixedly mounted on the support column, and the hemispherical shell fits the top plate.

[0013] Furthermore, the bottom plate and the top plate are connected by a screw rod, the screw rod and the thread are connected to the handle of the dynamic tool, and the handle of the dynamic tool is connected to the bottom plate in a longitudinal sliding manner, and a knob is fixedly installed at one end of the screw rod.

[0014] Furthermore, a coarse material feed port is provided on the top of the cylinder, and a fine material feed port and a discharge port are provided on the side thereof, the discharge port corresponds to the lower cutter disc, and a baffle is plugged into the discharge port, and the baffle is used to control the opening and closing of the discharge port.

[0017] 2. When the utility model feeds the coarse feed into the cylinder through the coarse feed inlet, the coarse feed entering the cylinder falls on the hemispherical shell, and the hemispherical shell is used to drop the feed to the surroundings of the upper cutter disc, thereby preventing the coarse feed from being concentrated around the rotating shaft and entangled with the rotating shaft, thereby affecting the rotation of the upper cutter disc and the lower cutter disc driven by the rotating shaft.

[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0029] See also Figure 1-Figure 5 As shown, the utility model is a feed crushing and mixing device for crayfish breeding, comprising a cylinder 1, a rotating shaft 2 is rotatably installed in the middle of the cylinder 1, an upper cutter disc 3 is fixedly installed on the rotating shaft 2, a plurality of stationary cutters 4 are fixedly installed on the upper cutter disc 3, and a dynamic cutter 5 is slidably installed on the upper cutter disc 3 along the axis direction thereof, the stationary cutters 4 and the dynamic cutters 5 are intermittently distributed with each other, and the distance between the stationary cutters 4 and the dynamic cutters 5 is adjustable.

[0030] In actual application, the upper cutter disc 3 is driven to rotate by the rotation of the rotating shaft 2, and the feed in the cylinder 1 is crushed by the static cutter 4 and the dynamic cutter 5 installed on the upper cutter disc 3. When the crushing accuracy of the feed needs to be adjusted, the dynamic cutter 5 slides on the upper cutter disc 3 to change the distance between the dynamic cutter 5 and the static cutter 4, so that the dynamic cutter 5 and the static cutter 4 form a staggered layer, and then the feed falls to the lower cutter after being crushed by the upper cutter, and is cut and crushed for the second time, so as to adjust the crushing accuracy of the feed, thereby solving the problem of low efficiency caused by the single form of the traditional crushing cutter.

[0031] When the dynamic tool 5 is adjusting its position, if the dynamic tool 5 is located above the stationary tool 4, the dynamic tool 5 is the upper tool and the stationary tool 4 is the lower tool; conversely, if the dynamic tool 5 is located below the stationary tool 4, the stationary tool 4 is the upper tool and the dynamic tool 5 is the lower tool.

[0032] In one embodiment, for the above-mentioned rotating shaft 2, one end of the rotating shaft 2 extends to the bottom of the cylinder 1, and the rotating shaft 2 is fixedly mounted on the output shaft of the motor 6, the motor 6 is fixedly mounted on the mounting seat 7, and the mounting seat 7 is fixedly mounted on the lower surface of the cylinder 1.

[0033] The motor 6 drives the rotating shaft 2 to rotate, so that the motor 2 provides a driving source for the rotating shaft 2 to drive the upper cutter disc 3 to rotate.

[0034] In one embodiment, for the lower cutter disc 8, the lower cutter disc 8 is fixedly mounted on the rotating shaft 2, and the lower cutter disc 8 is located below the upper cutter disc 3, and a plurality of blades 9 are fixedly mounted on the upper surface of the lower cutter disc 8.

[0035] Since the lower cutter disc 8 is also fixed on the rotating shaft 2, when the rotating shaft 2 rotates, the rotating shaft 2 synchronously drives the lower cutter disc 8 to rotate, and a plurality of blades 9 are fixedly installed on the upper surface of the lower cutter disc 8. Therefore, when the feed cut by the stationary cutter 4 and the dynamic cutter 5 falls on the lower cutter disc 8, the blades 9 are used to mix and further crush the feed, thereby realizing the integrated operation of crushing and mixing the feed in the cylinder 1.

[0036] In one embodiment, for the above-mentioned blade 9, the blade 9 is divided into an inner ring blade and an outer ring blade, the inner ring blade is irregularly distributed inside the upper surface of the lower blade disc 8, and the outer ring blade is evenly distributed outside the upper surface of the lower blade disc 8.

[0037] For the above-mentioned cylinder 1, a coarse material feed port 10 is arranged on the top of the cylinder 1, and a fine material feed port 11 and a discharge port 12 are arranged on the side thereof, the discharge port 12 corresponds to the lower cutter disc 8, and the discharge port 12 is plugged with a baffle 13, and the baffle 13 is used to control the opening and closing of the discharge port 12, thereby making feeding and discharging more convenient, and thus the machine operation is more convenient and quick.

[0038] The irregular blades 9 on the inner ring can fully crush the feed close to the rotating shaft 2 to prevent the feed from being entangled or adhering to the rotating shaft. Since the lower blade disc 8 rotates at a high speed, the lower blade disc 8 drives the feed thereon to rotate, and the feed is discharged from the discharge port 12 by the effect of centrifugation.

[0039] In one embodiment, for the above-mentioned cutter disc 3, the upper cutter disc 3 includes a bottom plate 301 and a top plate 302, the bottom plate 301 and the top plate 302 are fixedly connected via a support column 303, and a hemispherical shell 304 is fixedly mounted on the support column 303, and the hemispherical shell 304 fits with the top plate 302.

[0040] When feeding into the cylinder 1 through the coarse feed inlet 10, the coarse feed entering the cylinder 1 falls on the hemispherical shell 304, and the hemispherical shell 304 is used to drop the feed around the upper cutter disc 3, thereby preventing the coarse feed from being concentrated around the rotating shaft 2 and entangled with the rotating shaft 2, thereby affecting the rotation of the upper cutter disc 3 and the lower cutter disc 8 driven by the rotating shaft 2.

[0041] In one embodiment, for the above-mentioned chassis 301, the chassis 301 and the top plate 302 are both equipped with a rotating screw 305, the screw 305 is threadedly connected to the handle of the dynamic tool 5, and the handle of the dynamic tool 5 is longitudinally slidably connected to the chassis 301, and a knob 306 is fixedly installed at one end of the screw 305.

[0042] When the position between the stationary tool 4 and the dynamic tool 5 needs to be adjusted, the hemispherical shell 304 is removed from the top plate 302, and then 306 is rotated so that 306 drives the screw 305 to rotate. Since the screw 305 and the handle of the dynamic tool 5 are threadedly connected, when the screw 305 rotates, the screw 305 drives the handle of the dynamic tool 5 to slide longitudinally along the bottom plate 301, so as to adjust the position between the stationary tool 4 and the dynamic tool 5, thereby forming a double-layer tool.

[0043] The chassis 301 is provided with a slide groove, which is used to limit the freedom of the handle of the dynamic tool 5 so that it can only move in the longitudinal direction.

[0044] In summary, with the aid of the above technical solution of the utility model, through 1, the utility model utilizes the rotation of the rotating shaft 2 to make the rotating shaft 2 drive the upper cutter disc 3 to rotate, and utilizes the stationary cutter 4 and the dynamic cutter 5 installed on the upper cutter disc 3 to crush the feed in the cylinder 1. When the crushing accuracy of the feed needs to be adjusted, the dynamic tool 5 is made to slide on the upper cutter disc 3 to change the distance between the dynamic tool 5 and the stationary tool 4, so that the dynamic tool 5 and the stationary tool 4 form a staggered layer, and then the feed falls onto the lower cutter after being crushed by the upper cutter, and is cut and crushed for the second time, so as to adjust the crushing accuracy of the feed, thereby solving the problem of low efficiency caused by the single form of traditional crushing knives; 2. When the utility model feeds the feed into the cylinder 1 through the coarse material feed port 10, the coarse feed entering the cylinder 1 falls on the hemispherical shell 304, and the hemispherical shell 304 is used to drop the feed around the upper cutter disc 3, so as to prevent the coarse feed from concentrating around the rotating shaft 2 and winding around the rotating shaft 2, thereby affecting the rotation of the upper cutter disc 3 and the lower cutter disc 8 driven by the rotating shaft 2.
