Description

Technical Field

[0001] The utility model relates to the field of feed production, in particular to a duck feed drying device. Background Art

[0002] The existing duck feed drying methods mostly use a heating fan to blow air to dry the feed on the conveyor belt. When the feed is stacked, it is difficult to effectively dry the lower layer of feed, the drying speed is slow, and the drying effect is poor. A feed dryer disclosed in announcement number CN 212133208U conveys materials by rotating and vibrating a cam and uses a material-dispensing structure to break up the materials, thereby improving the drying efficiency. However, the design of the scheme is relatively idealized, the cam vibration mode is single and the amplitude cannot be adjusted. Different batches of feed have different moisture contents and different gravity sizes. For heavier materials, a larger amplitude is required to ensure sufficient drying while ensuring the conveying speed. For lighter materials, the amplitude needs to be reduced to reduce the conveying speed while avoiding material splashing and scattering. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model adopts a duck feed drying device to solve the problem of insufficient drying caused by the weight difference of different batches of materials in the prior art.

[0004] The technical solution is a duck feed drying device, comprising a supporting platform, wherein the upper end surface of the supporting platform is an inclined surface which is higher on the left and lower on the right; a vibrating plate which is placed horizontally with the upper end surface of the supporting platform is arranged on the upper side of the supporting platform; the vibrating plate is fixedly connected to the upper end surface of the supporting platform through a spring; vibrating rollers are arranged on the front and rear sides of the vibrating plate respectively; the vibrating roller is a cylindrical shell which is placed horizontally front and rear with its axis; a plurality of through holes are opened along the circumference of the vibrating roller; a push rod which can slide inside and outside the through hole is arranged in each through hole; the outer end of the push rod always extends out of the through hole; a sliding rod is coaxially arranged on the inner side of the vibrating roller; one end of the sliding rod passes through the shell of the vibrating roller; the outer edge surface of the sliding rod which is located inside the vibrating roller is a conical surface which contacts with the inner push rod; when the sliding rod moves toward the outside of the vibrating roller along the axis, the push rod can be squeezed outward through the conical surface; a nut is connected to the outer end of the sliding rod through a thread.

[0005] The vibration plate is a U-shaped plate with a downward depression in the middle, and a ventilation hole is provided on the lower end surface of the vibration plate.

[0006] A rotating shaft is fixed to one end of each vibration roller away from the nut, and support plates are respectively provided on the outer edge surfaces of the rotating shaft and the outer edge surfaces of the nut. Both the nut and the rotating shaft pass through the support plate, and the lower end of the support plate is fixedly connected to the support platform. A motor is provided on the support platform, and the other end of the rotating shaft is transmission-connected to the motor rotating shaft via a gear set.

[0007] The push rod is fixedly connected to the through hole via a compression spring, and the compression spring always gives the push rod an inward thrust.

[0008] One end surface of the ejector rod in contact with the sliding rod is provided with a through groove along the generatrix direction of the sliding rod. A strip-shaped block corresponding to the through groove one by one is fixed on the outer edge surface of the sliding rod along the generatrix direction, and the strip-shaped block is placed in the through groove.

[0009] One end surface of the nut close to the vibrating roller is provided with a plurality of strip-shaped grooves along the circumference. The strip-shaped grooves are arranged radially. One end of the vibrating roller close to the nut is provided with strip-shaped protrusions corresponding to the strip-shaped grooves one by one, and the strip-shaped protrusions can be placed in the strip-shaped grooves.

[0010] The utility model has the following advantages compared with the prior art:

[0011] 1. Vibration is realized by knocking the vibrating plate with the ejector rod on the vibrating roller, so that the feed can be turned over when passing through the vibrating plate, greatly improving the drying efficiency;

[0012] 2. The extension amount of the ejector rod is controlled by the axial movement of the sliding rod, and the height difference between the ejector rod and the outer edge surface of the vibrating roller is changed, so as to change the vibration amplitude of the vibrating plate. It is adjusted for feeds with different water contents and different weights to ensure that the speed and height of the material being vibrated and turned over are consistent, and to avoid the situation that the lower-layer material cannot be turned over due to the excessive weight of the material and the material splashing due to the too fast conveying speed caused by the too light material;

[0013] 3. The rotation of the sliding rod is restricted by the strip-shaped block and the through groove, and the rotation of the nut is restricted by the strip-shaped groove and the strip-shaped protrusion, effectively avoiding the problem of loosening of the thread fit in the vibration environment, making the connection more reliable, and ensuring the constant knocking amplitude of the ejector rod.

[0019] The following further elaborates on the detailed embodiment of the utility model in conjunction with the drawings.

[0020] From Figures 1 to 5The utility model comprises a supporting platform 1, the upper end face of the supporting platform 1 is an inclined surface which is higher on the left and lower on the right, a vibrating plate 2 which is horizontally placed with the upper end face of the supporting platform 1 is arranged on the upper side of the supporting platform 1, the vibrating plate 2 is fixedly connected with the upper end face of the supporting platform 1 through a spring, and a vibrating roller 3 is arranged on the front and rear sides of the vibrating plate 2 respectively, the vibrating roller 3 is a cylindrical shell which is horizontally placed front and back with its axis, a plurality of through holes 4 are opened along the circumference of the vibrating roller 3, each of the through holes 4 is provided with a push rod 5 which can slide inside and outside the through hole 4, the outer end of the push rod 5 always extends out of the outside of the through hole 4, a sliding rod 6 is coaxially arranged on the inner side of the vibrating roller 3, one end of the sliding rod 6 passes through the shell of the vibrating roller 3, the outer edge surface of the sliding rod 6 which is located inside the vibrating roller 3 is a conical surface and contacts with the inner push rod 5, when the sliding rod 6 moves along the axis toward the outside of the vibrating roller 3, the push rod 5 can be squeezed outward through the conical surface; a nut 7 is threadedly connected to the outer end of the sliding rod 5.

[0021] The vibration plate 2 is a U-shaped plate with a downward depression in the middle, and a ventilation hole is provided on the lower end surface of the vibration plate 2.

[0022] A rotating shaft 8 is fixed to one end of each vibration roller 3 away from the nut 7, and support plates 9 are respectively provided on the outer edge surfaces of the rotating shaft 8 and the outer edge surfaces of the nut 7. The nut 7 and the rotating shaft 8 both penetrate the support plate 9, and the lower end of the support plate 9 is fixedly connected to the support platform 1. A motor is provided on the support platform 1, and the other end of the rotating shaft 8 is transmission-connected to the motor shaft via a gear set.

[0023] The push rod 5 is fixedly connected to the through hole 4 via a compression spring, and the compression spring always gives the push rod 5 an inward thrust.

[0024] The end surface of the push rod 5 that contacts the slide rod 6 is provided with a through groove 10 along the generatrix direction of the slide rod 6, and a strip block 11 corresponding to the through groove 10 is fixed to the outer edge surface of the slide rod 6 along the generatrix direction, and the strip block 11 is placed in the through groove 10.

[0025] The nut 7 has a plurality of strip grooves 12 circumferentially formed on one end face close to the vibration roller 3 . The strip grooves 12 are arranged radially. The vibration roller 3 has a strip protrusion 13 corresponding to the strip grooves 12 on one end close to the nut 7 . The strip protrusion 13 can be placed in the strip groove 12 .

[0026] When the utility model is in use, a motor drives a rotating shaft 8 and a vibrating roller 3 to rotate through a gear set. Under the action of the spring tension, the lower end surface of a vibrating plate 2 is always in contact with the vibrating roller 3 and a push rod 5. Due to the height difference between the push rod 5 and the vibrating roller 3, during the rotation of the vibrating roller 3, the vibrating roller 3 can continuously knock the vibrating plate 2 through the push rod 5, causing the vibrating plate 2 to vibrate up and down continuously. When it is necessary to adjust the extending length of the push rod 5, only need to manually pull a nut 7 to move outwards until a strip groove 12 disengages from a strip projection 13, and then rotate the nut 7. Since a slide rod 6 is restricted by a strip block 11 and a through groove 10 and cannot rotate with the nut 7, the rotation of the nut 7 relative to the slide rod 6 causes the slide rod 6 to move outwards and shorten the distance between the nut 7 and the tapered surface of the slide rod 6. Then release the nut 7, and the slide rod 6 resets inwards under the action of the compression spring on the push rod 5, causing the strip projection 13 to be placed in the strip groove 12 again to restrict the rotation of the nut 7. Since the distance between the nut 7 and the tapered surface of the slide rod 6 is shortened, the extending length of the outer end of the push rod 5 increases, the height difference between the push rod 7 and the outer edge surface of the vibrating roller 3 increases, and the vibration amplitude of the vibrating plate 2 increases.

[0027] The utility model realizes vibration by knocking a vibrating plate 2 through a push rod 7 on a vibrating roller 3, so that the feed can be turned over when passing through the vibrating plate 2, greatly improving the drying efficiency; controls the extending amount of the push rod 5 by the axial movement of a slide rod 6, changes the height difference between the push rod 5 and the outer edge surface of the vibrating roller 3, thereby changing the vibration amplitude of the vibrating plate 2, and adjusts for feeds with different water contents and different weights to ensure that the speed and height of the material being vibrated and turned over are consistent, and avoid the situations that the lower-layer material cannot be turned over due to the excessive weight of the material and the material splashes due to the too-fast conveying speed caused by the too-light weight of the material; restricts the rotation of the slide rod 6 through a strip block 11 and a through groove 10, and restricts the rotation of the nut 7 through a strip groove 12 and a strip projection 13, effectively avoiding the problem that the thread fit loosens in a vibrating environment, making the connection more reliable, and ensuring that the knocking amplitude of the push rod 5 is constant.
