An artificial hand mechanism

Abstract

This invention provides a simulated manual material collection mechanism, including a frame and a conveyor bucket, a material-pushing mechanism, and a tilting mechanism mounted on the frame. The material-pushing mechanism propels the bucket forward, and the tilting mechanism drives the bucket to tilt onto the conveyor. The material-pushing mechanism and the tilting mechanism are linked. During the material-pushing process, the bucket initially rests against the ground and has floating capability, adapting well to uneven ground and ensuring accurate starting point for shoveling the mash. Simultaneously, with the synchronous movement of the spreading machine, the actual material-pushing distance of the bucket is the sum of the distance driven by the connecting rod and the travel distance of the spreading machine. Compared to the fixed material-pushing distance design of existing mechanisms, this significantly increases the amount of material shoveled per cycle, improving collection efficiency. Furthermore, when the bucket tilts to unload, the driver simultaneously pulls the sliding seat back to its initial position, effectively offsetting the travel distance of the spreading machine and covering areas where material may slip during shoveling, thoroughly cleaning residual mash on the spreading area.

Description

Technical Field

[0001] This invention relates to the field of brewing equipment technology, specifically to a manual material collection mechanism. Background Technology

[0002] In the brewing process of Maotai-flavor liquor, the spreading and cooling process requires dealing with high-temperature materials and completing the spreading and cooling within a short period of time, resulting in high labor intensity and a poor working environment. Currently, automated, manual-like ground spreading and cooling equipment is gradually being recognized by major Maotai-flavor liquor producers. To further reduce labor intensity and optimize the working environment, automated, manual-like ground spreading and cooling machines not only need to possess basic functions such as spreading, adding yeast, sprinkling tail liquor, and kneading yeast, but also must have an automatic material collection function. A key development direction for ground spreading and cooling equipment is achieving the effect of collecting materials without damaging the material clumps, without compressing the clumps, and with clean collection during the fully automated material collection process.

[0003] For the reasons mentioned above, there are currently some devices on the market for shoveling and recycling materials. For example, a shoveling machine for a spreading machine, disclosed in Chinese Patent Publication No. CN223341918U, includes a support frame, a geared motor, several sets of sprockets, and a ring conveyor belt formed by several chain plates hinged together. The shoveling machine of this spreading machine uses a collecting shovel to scoop up the fermented mash from the ground, and then uses a pushing shovel to push the fermented mash onto a toothed shovel. The toothed shovel then transports the fermented mash to a receiving dish, forming a circular material collection process.

[0004] The above equipment uses a continuously rotating shovel to turn the mash up from the ground, a collecting shovel to scoop it up, and then a toothed shovel on a conveyor belt to transport the material upwards. However, during the shoveling process, some mash leaks out from the gaps at the bottom of the collecting shovel due to the continuous shoveling. Simultaneously, due to the continuous collecting, mash also overflows from the front and back of the shovel bucket, resulting in incomplete shoveling and significant leakage. Secondly, as the toothed shovel pushes the material backwards, it crushes and breaks up clumps of mash, then reassembles them. When these clumps form a pile, they cause uneven fermentation of the mash in the saccharification pile, creating noticeable "waistlines" that significantly impact the quality of the liquor.

[0005] This case arose from the aforementioned issues. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a simulated manual material receiving mechanism, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a simulated manual material receiving mechanism, characterized in that: it includes a frame and a conveyor, a bucket, a material feeding mechanism and a tilting mechanism mounted on the frame, wherein the material feeding mechanism is used to push the bucket forward, the tilting mechanism is used to drive the bucket to tilt onto the conveyor, and the material feeding mechanism and the tilting mechanism can be linked.

[0008] Preferably, the shovel pushing mechanism includes a connecting rod, a sliding seat, and a crank-connecting rod assembly. The frame is provided with a slide rail for the sliding seat to slide laterally. The front end of the connecting rod is connected to the bucket, and the rear end is coaxially hinged to the connecting rod of the crank-connecting rod assembly on the sliding seat.

[0009] Preferably, the crank-connecting rod assembly includes a driver, a crank, and a connecting rod. The driver is mounted on the frame and is hinged to the connecting rod via the crank. The other end of the connecting rod is coaxially hinged to the connecting rod on a sliding seat.

[0010] Preferably, the flipping mechanism includes a movable frame, a second driver, a second crank, and a third connecting rod. The movable frame is fixed on a sliding seat, the second driver is mounted on the movable frame and is hinged to the third connecting rod via the second crank, and the other end of the third connecting rod is hinged to the middle section of the first connecting rod.

[0011] Preferably, the bucket is movably mounted on the connecting rod via a floating mechanism, and the bucket can float up and down when it encounters resistance under the action of the floating mechanism.

[0012] Preferably, the floating mechanism includes several sets of T-shaped shafts and U-shaped sleeves. The tail end of the bucket is rotatably mounted on the connecting rod one via a rotating shaft. The T-shaped shafts are arranged and fixed on the bucket, and the U-shaped sleeves are arranged and fixed on the front end of the connecting rod one, each corresponding to a T-shaped shaft. The T-shaped shafts are vertically movably adapted to the U-shaped sleeves.

[0013] Preferably, the bucket is composed of several identical small buckets, the number of which is determined by the material collection width.

[0014] Preferably, the bucket is through-type, and a discharge mechanism is provided at the rear outlet of the bucket. The discharge mechanism includes a cover plate, a drive rod, and a third driver. The cover plate is rotatably mounted on a connecting rod via a drive shaft. The cover plate can cover the rear outlet of the bucket. One end of the drive rod is fixed to the drive shaft. The back of the third driver is hinged to the connecting rod, and its output end is hinged to the other end of the drive rod.

[0015] Preferably, the cover plate is bent, and when the bucket swings around the pivot, the cover plate swings around the drive shaft.

[0016] This invention provides a simulated manual material receiving mechanism. It has the following beneficial effects: 1. This simulated manual material collection mechanism features a bucket initially in contact with the ground during the shoveling process, while also possessing floating capability. This adapts well to uneven ground, ensuring precise starting point for shoveling the mash. Simultaneously, with the synchronized movement of the spreading machine, the actual shoveling distance is the sum of the distance driven by the connecting rod and the travel distance of the spreading machine. Compared to the fixed shoveling distance design of existing mechanisms, this significantly increases the amount of material shoveled per pass, improving collection efficiency. Furthermore, when the bucket flips over to unload, the drive unit simultaneously pulls the sliding seat back to its initial position, effectively offsetting the travel distance of the spreading machine and covering areas where material may slip during shoveling. This thoroughly cleans the residual mash on the spreading area, fundamentally solving the problems of incomplete shoveling, waste, and damage to the mash clumps inherent in existing mechanisms.

[0017] 2. This simulated manual material collection mechanism, through the inclusion of a floating mechanism, allows the bucket to float up and down when encountering uneven surfaces during its movement. Simultaneously, the weight of the bucket and the fermented mash keeps the bucket pressed against the ground, ensuring it moves close to the surface even on uneven terrain. This avoids jamming or damage to the bucket caused by hard contact with the ground, and also prevents damage to the ground itself. Furthermore, it allows for more thorough collection of fermented mash from the ground. Attached Figure Description

Detailed Implementation

[0020] This invention provides a simulated manual material receiving mechanism, such as... Figure 1-8 As shown, it includes a frame 5 and a conveyor 1, a bucket 2, a material feeding mechanism 3, and a tilting mechanism 4 mounted on the frame 5.

[0021] The material pushing mechanism 3 is used to push the bucket 2 forward, and the tilting mechanism 4 is used to drive the bucket 2 to tilt onto the conveyor 1. The material pushing mechanism 3 and the tilting mechanism 4 can be linked to realize the continuous action of shoveling, tilting, unloading and resetting.

[0022] The shovel propulsion mechanism 3 includes two sets of connecting rods 31, a sliding seat 33, and a crank-connecting rod assembly. The frame 5 is provided with a slide rail 32 for the sliding seat 33 to slide laterally. The sliding seat 33 is provided with multiple pulleys 37 that are adapted to slide along the slide rail 32 to ensure smooth movement of the sliding seat 33. The front end of the connecting rod 31 is connected to the bucket 2, and the rear end is coaxially hinged to the connecting rod of the crank-connecting rod assembly on the sliding seat 33.

[0023] like Figure 1 As shown, specifically, the crank-connecting rod assembly includes a driver 35, a crank 36, and a connecting rod 34. The driver 35 is mounted on the frame 5 and employs a combination of a servo motor and a reducer. The output shaft of the reducer is fixedly connected to the shaft of the crank 36. The protruding end of the crank 36 is hinged to one end of the connecting rod 34, and the other end of the connecting rod 34 is coaxially hinged to the sliding seat 33 along the connecting rod 31. By driving the crank 36 to rotate, the connecting rod 34 is driven to reciprocate, thereby pushing the sliding seat 33 to slide laterally along the slide rail 32. This enables the connecting rod 31 to drive the bucket 2 forward and backward, simulating the pushing action when manually shoveling material. The forward speed of the bucket 2 can be adjusted according to the thickness and looseness of the mash.

[0024] The crank-36 shafts of the two sets of crank-connecting rod assemblies are coaxially connected via the linkage shaft-38.

[0025] like Figure 2As shown, the tilting mechanism 4 includes a movable frame 41, a second driver 42, a second crank 43, and a third connecting rod 44. The movable frame 41 is fixed on the sliding seat 33 and moves laterally together with the sliding seat 33. The movable frames 41 on both sides are connected by a fixed shaft 46. The second driver 42 also adopts a combination of a servo motor and a reducer. The output shaft of the second driver 42 is fixedly connected to the rotating shaft of the second crank 43. The rotating shafts of the two cranks 43 on both sides are coaxially connected by a linkage shaft 45. The other end of the second crank 43 is hinged to one end of the third connecting rod 44, and the other end of the third connecting rod 44 is hinged to the middle section of the first connecting rod 31. When the second driver 42 drives the second crank 43 to rotate, the third connecting rod 44 pulls the middle section of the first connecting rod, causing the first connecting rod 31 to rotate around its hinge point with the sliding seat 33, thereby driving the bucket 2 to tilt, ensuring that the mash in the bucket 2 can be smoothly poured into the receiving plate 13 of the conveyor belt 12.

[0026] The conveyor 1 includes a support frame 11 and a circulating conveyor belt 12 mounted on the support frame 11. Arc-shaped receiving plates 13 are spaced on the conveyor belt 12.

[0027] like Figure 1 As shown, the conveyor 1 includes a support frame 11 and a circulating conveyor belt 12 mounted on the support frame 11. Arc-shaped receiving plates 13 are spaced along the conveyor belt 12. The conveyor belt 12 is not limited to chain conveyors or belt conveyors; any conveyor capable of conveying can be used. The conveyor belt 12 is inclined backwards. The function of the conveyor 12 is to transport the material on the receiving plates 13 from bottom to top into the hopper behind. The arc-shaped receiving plates 13 are spaced along the conveying direction, forming a space that can accommodate the material and better catch the mash falling from the bucket 2, preventing spillage.

[0028] The bucket 2 is open at both ends, with the front side for feeding and the rear side for discharging. The bucket 2 consists of several identical small buckets 21, the number of which is determined by the width of the receiving area. Each small bucket 21 can float up and down independently, better adapting to uneven conditions in the spreading area. The open structure makes it easier for the mash to enter the bucket, reducing the accumulation of mash in the feeding direction.

[0029] Several small buckets 21 are movably mounted on the connecting rod 31 via a floating mechanism 6. The small buckets 21 can float up and down when they encounter resistance under the action of the floating mechanism 6.

[0030] like Figure 4As shown, the floating mechanism 6 includes several sets of T-shaped shafts 61 and U-shaped sleeves 62. The top end of each small bucket 21 is rotatably mounted on the connecting rod 31 via a rotating shaft 63. The T-shaped shafts 61 are fixed to the top front end of each small bucket 21. The U-shaped sleeves 62 are arranged and fixed to the front end of the connecting rod 31, and each corresponds to a T-shaped shaft 61. The U-shaped sleeves 62 are horizontally arranged with their openings facing outwards. The opening diameter of the U-shaped sleeves 62 is larger than the lower section of the T-shaped shaft 61 and smaller than the top cap of the T-shaped shaft 61. The T-shaped shaft 61 is vertically movably adapted to the U-shaped sleeves 62, and the top cap of the T-shaped shaft 61 is located above the U-shaped sleeves 62.

[0031] By setting up the floating mechanism 6, when the small buckets 21 encounter an uneven surface during their movement, the small buckets 21 can float upwards. Simultaneously, under the weight of the small buckets 21 and the fermented mash, they can be pressed down to move along the ground. Even on uneven ground, they can move close to the ground, avoiding jamming or damage to the small buckets 21 due to hard contact with the ground, and also preventing damage to the ground. This also allows for more thorough collection of fermented mash from the ground.

[0032] A discharge mechanism 7 is provided at the rear outlet of bucket 2. The function of the discharge mechanism 7 is to prevent material spillage during bucket tipping. The discharge mechanism 7 includes a cover plate 71, a drive rod 74, and a driver 73. The cover plate 71 is rotatably mounted on a connecting rod 31 via a drive shaft 72. The cover plate 71 can cover the rear outlet of bucket 2. One end of the drive rod 74 is fixed to the drive shaft 72. The back of the driver 73 is hinged to the connecting rod 31, and its output end is hinged to the other end of the drive rod 74. The driver 73 is a cylinder or an electric push rod. The driver 73 drives the drive rod 74 to swing, thereby causing the drive shaft 72 and the cover plate 71 to rotate around the drive shaft 72, thus realizing the discharge of material from bucket 2.

[0033] In order to enable the cover plate 71 to swing along with the swing of the bucket 2, the cover plate 71 is bent. The bending angle is calculated according to the installation position of the drive shaft 72. When the bucket 2 swings around the pivot 63, the cover plate 71 swings around the drive shaft 72.

[0034] Working principle: such as Figure 5 This is the initial loading state, where bucket 2 is flat on the ground. The starting point of bucket 2 is as follows: Figure 5 As shown; then the shoveling action begins, as... Figure 6 As shown, the driver 35 starts working, driving the crank 36 to rotate, which pushes the sliding seat 33 along the slide rail 32 towards the surface of the spreading machine via the connecting rod 34. The sliding seat 33 drives the connecting rod 31 and the bucket 2 forward. The bucket 2 inserts into the spread mash, completing the shoveling action. Since the spreading machine moves forward synchronously during the shoveling process, the shoveling distance of the bucket 2 is the distance driven by the connecting rod 31 plus the distance traveled by the spreading machine; then, as... Figure 7As shown, the second driver 42 starts, driving the second crank 43 to rotate, which pulls the middle section of the first connecting rod through the third connecting rod 44, causing the first connecting rod 31 to rotate around the hinge point, driving the bucket 2 to flip towards the conveyor 1; at the same time, the first driver 35 works synchronously, pulling the sliding seat 33 back to its initial position. This action pulls the scooping position of the bucket 2 backward a certain distance to offset the stroke of the spreader and the area where some material slips off the bucket 2 during scooping; when the bucket 2 flips to a suitable angle, the mash in the bucket 2 falls onto the conveyor belt 12 of the conveyor 1 under the action of gravity, and is received by the arc-shaped receiving plate 13; subsequently, as Figure 8 As shown, the second driver 42 works in reverse, causing the bucket 2 to flip and reset, so that the bucket 2 is behind the end point of the previous scooping, ready for the next scooping.
