Description

Technical Field

[0001] The utility model relates to the technical field of wine-making equipment, in particular to a shovel machine for a drying machine. Background Art

[0002] During the brewing process of Maotai-flavor liquor, the drying process requires handling high-temperature materials in a short period of time, resulting in high labor intensity and a poor working environment. Currently, automated, manual-like floor drying equipment is gaining acceptance among major Maotai-flavor liquor manufacturers. To further reduce labor intensity and optimize the working environment, automated, manual-like floor drying machines must not only perform the basic functions of drying, adding koji, spreading the tail liquor, and mixing the koji, but also automatically collect the materials. Achieving a clean, fully automated material collection process without clumping or squeezing is a key development direction for floor drying equipment.

[0003] Based on the above reasons, there are some equipment for shoveling material recovery on the market, such as a lifting device of a ground drying machine with Chinese patent publication number CN217324016U, which includes a lifting drive device fixed on the drying machine, one end of the lifting drive device is hinged with a lifting assembly, the lifting assembly includes a bucket, a material baffle plate is fixed on the connecting plate, one end of the bucket is hinged to the connecting plate, and side baffles are provided on both sides of the bucket.

[0004] Although the above equipment can scoop up the mash from the ground, a large amount of mash accumulates on the shovel head and is squeezed, which is easy to form a mass and squeeze, and the efficiency is low, and there is serious leakage on both sides. Utility Model Content

[0013] (3) Beneficial effects

[0014] The utility model provides a scraper for a drying machine, which has the following beneficial effects:

[0015] 1. The shovel of this drying machine scoops up the mash from the ground with a collecting blade and uses a spreading blade to spread the mash onto a toothed blade.

DETAILED DESCRIPTION

[0023] The present invention provides a shovel for a drying machine, such as Figure 1-4 As shown, the scraper is fixed on the drying machine through a support column 1.

[0024] The shovel machine includes a bracket 2, a reduction motor 3, several groups of sprockets 4, and an endless conveyor belt hingedly connected by several chain plates 5. The bracket 2 is arranged on a screw screw elevator, and several groups of sprockets 4 are arranged on the bracket 2 along the length direction of the bracket 2 through a rotating shaft. The endless conveyor belt is engaged with the outside of the sprocket 4, and several chain plates 4 form an endless conveying closed loop. The reduction motor 3 is arranged on the bracket 2. The reduction motor 3 is used to drive the sprocket 4. The reduction motor 3 is an existing mature component.

[0025] The chain plate 5 is provided with arc-shaped toothed scrapers 6 at intervals, and the arc direction is to extend in an arc shape in the positive direction and upward direction toward the conveying direction of the chain plate 5. Figure 3 As shown, when the toothed scraper 6 is on the back of the conveyor belt moving downward, the end of the toothed scraper 6 is bent downward, and when the toothed scraper 6 is on the front of the conveyor belt moving upward, the end of the toothed scraper 6 is bent upward.

[0026] like Figure 3 As shown, a container for receiving materials is provided on the airing machine, and a drop guide plate 16 is provided on the top rear side of the bracket 2 for guiding the materials conveyed by the toothed scraper 6 to the receiving container. As the toothed scraper 6 scoops up the materials and conveys them to the top of the conveyor belt, the toothed scraper 6 flips the materials onto the drop guide plate 16, and the materials slide through the drop guide plate 16 into the receiving container.

[0027] like Figure 4As shown, support column 1 is provided with a lifting mechanism for adjusting the height of bracket 2. The lifting mechanism includes a screw jack 7, a fixed track 17, and a plurality of rollers 18. Screw jack 7 is fixed to the fixed track 17. The plurality of rollers 18 are provided on bracket 2 and slideably fit within the fixed track 17. The lifting shaft of screw jack 7 is connected to bracket 2. Screw jack 7 can be an SJA screw jack, an existing mature product. The screw jack 7 can be used to adjust the distance between the toothed scraper 6 and the ground according to process requirements.

[0028] The lifting mechanism is used to lift the entire shovel machine. When the equipment is in the process of spreading, removing stems, adding koji, and mixing koji, the entire shovel conveying component is in an upward state, and there is a lifting distance from the ground. When it is necessary to collect the material, it is lowered and the collecting shovel blade 12 is adjusted to contact the ground.

[0029] like Figure 2 As shown, a material-discharging mechanism is provided at the front end of the bottom of the bracket 2. The function of the material-discharging mechanism is similar to that of the material-discharging device at the front end of a harvester. The material-discharging mechanism includes a swing arm 8, a driving shaft 9, and a drive motor 11. One end of the swing arm 8 is fixed to the bracket 2 and extends horizontally along the front end of the lowest toothed scraper 6. The driving shaft 9 is rotatably arranged at the top end of the swing arm 8. The drive motor 11 is arranged on the swing arm 8 and is coaxially connected to the driving shaft 9. A number of material-discharging blades 10 are provided in the outer circumference of the driving shaft 9. The distance between the material-discharging blade 10 and the toothed scraper 6 is negative. The tooth profiles of both are triangular and are arranged at equal intervals along the longitudinal direction. The triangular teeth on the material-discharging blade 10 and the toothed scraper 6 are arranged alternately. Even if the distance between the two is negative, they can still rotate normally. Since there is no distance gap between the two, most of the material scooped up by the material-discharging blade 10 can be received by the toothed scraper 6, thereby improving the shoveling effect of the toothed scraper 6.

[0030] To prevent direct contact between the toothed scraper 6 and the ground, the toothed scraper 6 is kept away from the ground during scraping. A collecting scraper 12 is provided below the bottommost toothed scraper 6 for scooping up the mash. The collecting scraper 12 is made of a plastic material, such as PVC. An adjustment mechanism for adjusting the angle of the collecting scraper 12 is provided on the rear side of the bottom of the bracket 2.

[0031] Specifically, such as Figure 3As shown, the adjustment mechanism includes an adjustment arm 13, several cylinders 14, and several support shafts 15. The adjustment arm 13 is connected to the bracket 2. Several support shafts 15 are arranged longitudinally and independently pivoted to the adjustment arm 13. Each support shaft 15 is equipped with a collecting blade 12. The collecting blade 12 on each support shaft 15 is independently controlled by a cylinder 14. The base of the cylinder 14 is hinged to the adjustment arm 13, and its output end is hinged to the corresponding collecting blade 12. Due to the unevenness of the drying surface or the uneven distribution of materials, the collecting blades 12 in the longitudinal direction are divided into multiple groups and distributed on multiple support shafts 15. The angle of the corresponding collecting blade 12 can be adjusted by the corresponding cylinder 14 using a PLC controller. The contact pressure between the collecting blade 12 and the ground can be adjusted by the rear cylinder 14 to ensure that the collecting blade 12 remains close to the ground during the collecting process. The collecting blade 12 is arranged in multiple sections to further conform to the ground and eliminate the impact of uneven ground. By adjusting the air pressure of the air cylinder 14 , the collecting blade 12 can be effectively fitted to the ground without damaging the ground.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
