Description

Technical Field

[0001] This application relates to the technical field of brewing, and particularly to an automatic grain moistening machine. Background Art

[0002] Grain moistening is an important link in the production process of high-grade Maotai-flavor liquor. Its purpose is to enable sorghum to absorb sufficient moisture, causing the starch in the sorghum to expand initially and the cells of the starch granules to rupture, thereby releasing starch and providing guarantee for saccharification and fermentation. Therefore, the control of the grain moistening process parameters and the operation of the process are related to the success or failure of liquor production. In the existing grain moistening operation, the traditional method is adopted by the liquor production team for grain moistening water injection: that is, after filling water in a stainless-steel grain moistening barrel, it is carried by hand to the grain pile and then poured onto the grain fermented grains. During the water injection process, the grains at the bottom of the grain pile need to be turned to the top. After the water injection is completed, two people work face to face in a group and use shovels to shovel and throw the grains of the grain pile to the side at the same time, so that the dry and wet grains are evenly mixed. The whole process from water release, water lifting to water pouring is manually operated barefoot.

[0003] This method has the following deficiencies: 1) It is easy to spill water during the water lifting process, the measurement of each barrel of water is inaccurate, and the actual water injection volume into the grain pile has a large error; 2) The temperature of the grain moistening water is relatively high, and there are potential safety hazards of scalding during the water lifting and pouring processes; 3) The water lifting personnel operate barefoot, which is easy to slip and there are potential safety hazards of falling and scalding; 4) The operation is not convenient and the labor intensity is high. At the same time, during the process of turning and shoveling the grains, two people need to take turns to work continuously in a group, and at least two repetitions are required for one pile, with extremely high labor intensity.

[0034] An embodiment of the present utility model provides an automatic grain moistening machine, which includes:

[0035] A stirring container 1, configured to load grains to be moistened with water. A stirring structure 2 is arranged in the stirring container 1, and the stirring structure 2 is driven by a power device 5 arranged on the stirring container 1;

[0036] A support frame 3, and the stirring container 1 is rotatably arranged on the support frame 3;

[0037] A telescopic mechanism 4, one end of which is hinged to the support frame 3 and the other end is hinged to the stirring container 1. The telescopic mechanism 4 has a first state and a second state, and among them:

[0038] When the telescopic mechanism 4 is in the first state, the telescopic mechanism 4 cooperates with the support frame 3 to provide support for the stirring container 1, so that the material opening of the stirring container 1 faces upward;

[0039] During the process of the telescopic mechanism 4 switching from the first state to the second state, the telescopic mechanism 4 can drive the stirring container 1 to rotate around the support frame 3 until the material opening of the stirring container 1 faces downward;

[0040] The first state is one of the retracted state and the extended state, and the second state is the other.

[0041] The automatic grain moistening machine provided by the embodiment of the present utility model can drive the stirring structure 2 through the power device 5, stir and mix grains and water, and then realize the automatic moistening of grains. On the premise of ensuring the grain moistening effect, the manual labor intensity is greatly reduced. By hingedly arranging the telescopic mechanism 4 between the support frame 3 and the stirring container 1, the telescopic mechanism 4 can be maintained in the first state during grain moistening. At this time, the telescopic mechanism 4 serves as a support member, and together with the support frame 3, it can provide support for the stirring container 1, keep the material opening of the stirring container 1 facing upward, and prevent the stirring container 1 from shaking around the support frame 3 during grain moistening, ensuring the stability of the stirring container 1, so as to facilitate the stirring and moistening of the grains inside the stirring container 1; during unloading, the telescopic mechanism 4 can be switched from the first state to the second state.

[0043] The following will give a detailed description of the automatic grain moistening machine provided by the embodiment of the present utility model with reference to the accompanying drawings.

[0044] According to Figure 1 Exemplarily shown is the automatic grain moistening machine of at least one embodiment of the present utility model. The automatic grain moistening machine includes: a support frame 3, a stirring container 1, and a telescopic mechanism 4.

[0045] In this embodiment, the support frame 3 is the body of the automatic grain moistening machine, used to provide installation support for components such as the stirring container 1, the telescopic mechanism 4, and the control box, and it can be a frame of any structural form.

[0046] For example, see Figure 1, which exemplarily shows that the support frame 3 includes a bottom frame 303, a left support 301, a right support 302, and a rear support 304. Among them, both the left support 301 and the right support 302 are vertical supports and are relatively fixed on the left and right sides of the bottom frame 303. The part between the left support 301 and the right support 302 is the space for installing the stirring container 1. The rear support 304 is fixed on the rear side of the bottom frame 303 and is the operating support of the automatic grain moistening machine for installing a control box, etc. The front side of the bottom frame 303 is the discharging side for placing a receiving bucket, etc. It can be understood that in this embodiment, the connection methods between the left support 301, the right support 302, and the rear support 304 and the bottom frame 303 can be welding, bolt connection, etc. The left and right sides of the bottom frame 303 are the two sides of the bottom frame 303 along the width direction, and the front and rear sides are the two sides of the bottom frame 303 along the length direction.

[0047] Further, in some embodiments, a plurality of moving wheels 7 are further provided on the bottom frame 303. For example, see Figure 1 , four moving wheels 7 are provided on the bottom frame 303, and the moving wheels 7 are universal wheels. With such a setting, the automatic grain moistening machine can be transferred through the moving wheels 7, and the operation is more convenient.

[0048] In this embodiment, the stirring container 1 is a container for moistening grains, which is used to load water and grains to be moistened with water during grain moistening. See Figure 1 , which is arranged between the tops of the left support 301 and the right support 302 in a rotatable form. For example, the left and right sides of the stirring container 1 are rotationally connected to the left support 301 and the right support 302 through a rotating shaft, so that the stirring container 1 can be turned around the connection points with the left support 301 and the right support 302. With such a setting, when grain moistening is required, the material opening of the stirring container 1 is facing upwards, so that the grains and water can be prevented from being discharged. When discharging is required, the stirring container 1 is turned until the material opening is facing downwards, and the automatic discharging of the stirring container 1 can be realized.

[0049] Specifically, in this embodiment, the stirring container 1 can be any container with a suitable structure, such as a tank body, a barrel body, etc. See Figure 1 , in this embodiment, the stirring container 1 is preferably a cylindrical stirring barrel with an open top, and the open top of the stirring barrel is the material opening. Based on this structural design, combined with the stirring structure 2, the regular movement of grains in the stirring container 1 can be realized, and then the uniform moistening of grains can be realized, and the uniformity of grain moistening is better.

[0050] See Figure 1 , in this embodiment, the stirring structure 2 is arranged in the stirring container 1 and is driven by a power device 5. During grain moistening, the power device 5 drives the stirring structure 2 to stir and mix the grains and water in the stirring container 1, and the automatic moistening of grains can be realized. On the premise of ensuring the grain moistening effect, the manual labor intensity is greatly reduced.

[0051] For details, see Figure 1 and Figure 2 In this embodiment, the power device 5 is a reduction motor, which is fixedly arranged at the bottom of the stirring container 1. The stirring structure 2 includes a stirring shaft 201 and a stirring blade 202, wherein the stirring shaft 201 is rotatably arranged in the stirring container 1, and the lower end of the stirring shaft 201 passes through the stirring container 1 downward and is connected to the reduction motor at the bottom of the stirring container 1 through a transmission member such as a chain, and the stirring blade 202 is fixed on the stirring shaft 201. In this arrangement, when moistening the grain, the reduction motor drives the stirring shaft 201 to rotate, and the stirring shaft 201 drives the stirring blade 202 to apply a driving force to the grain, so that the grain and water are evenly stirred and mixed, thereby achieving the effect of evenly moistening the grain.

[0052] For further information, see Figure 1 In this embodiment, a mounting frame 6 is further provided on the top of the stirring container 1. The mounting frame 6 is formed by two fixed rods arranged crosswise, and a fixed seat is provided at the intersection of the mounting frame 6. The upper end of the stirring shaft 201 is rotatably matched with the fixed seat through a rotating member such as a bearing. In this way, the mounting frame 6 can provide rotational positioning for the upper end of the stirring shaft 201, thereby improving the rotational stability of the stirring structure 2 and facilitating the grain moistening operation.

[0053] For further information, see Figure 1 and Figure 2 In this embodiment, the stirring shaft 201 is located on the axis of the stirring container 1, and the stirring blade 202 is a spiral lifting blade. In this arrangement, since the stirring blade 202 is a spiral blade, when the stirring blade 202 rotates with the stirring shaft 201, in the axial direction, the stirring blade 202 can lift the grain at the bottom of the stirring container 1 from the middle of the stirring container 1 upward, and after the grain is lifted to the top of the stirring container 1, it moves downward from the surroundings of the stirring structure 2 under the action of gravity, realizing the up and down circulation of the grain. In the circumferential direction, the stirring blade 202 can drive the grain to move circumferentially around the center of the stirring container 1, realizing the circumferential circulation of the grain. In this way, the circumferential movement of the grain in multiple directions can be realized, making it more evenly mixed, and further enhancing the grain moistening effect.

[0054] For further information, see Figure 2, in this embodiment, the lower part of the stirring barrel is a cone with a larger upper part and a smaller lower part, and the inner diameter of the bottom of the conical lower part of the stirring barrel is adapted to the rotation diameter of the stirring blade 202, that is to say, the diameter of the conical bottom of the stirring barrel is equal to or slightly larger than the rotation diameter of the stirring blade 202. With such a setting, the grains sliding down in the stirring container 1 can gather along the inner wall of the cone to the center of the bottom of the stirring container 1, that is, the grains are located on the lifting path of the stirring structure 2, so that all the grains falling to the bottom of the stirring container 1 can be lifted to the top of the stirring container 1 by the stirring structure 2, making the comprehensiveness of the up-and-down circulation of the grains better and the uniformity of grain moistening better.

[0055] See Figure 1 and Figure 4 , in this embodiment, the telescopic mechanism 4 is hinged between the support frame 3 and the stirring container 1, and is mainly used to be in the first state during grain moistening, and cooperate with the support frame 3 as a support member to provide support for the stirring container 1 to ensure that the material port of the stirring container 1 faces upward; and when discharging is required, as a flipping driving member, it switches from the first state to the second state to drive the stirring container 1 to flip until the material port faces downward to achieve automatic discharging.

[0056] Among them, the first state is one of the retracted state and the extended state, and the second state is the other. For example, if the first state is the retracted state, then the second state is the extended state; if the first state is the extended state, then the second state is the retracted state.

[0057] For example, see Figure 4 , in this embodiment, the first state is the retracted state, the second state is the extended state, the telescopic mechanism 4 is inclinedly arranged at the rear side of the bracket, and the lower end of the telescopic mechanism 4 deviates backward, and in the retracted state, the material port of the stirring container 1 faces upward, and when the telescopic mechanism 4 extends outward, it can push the stirring container 1 to flip forward around the bracket, so that the material port of the stirring container 1 faces downward.

[0058] Specifically, see Figure 4, in this embodiment, the upper end of the telescopic mechanism 4 is hinged to the side wall of the mixing container 1 through a pin shaft, and the upper end of the telescopic mechanism 4 is located at the rear side of the connection point between the mixing container 1 and the bracket. The lower end of the telescopic mechanism 4 is hinged to the chassis 303 through a pin shaft, and the lower end of the telescopic mechanism 4 is offset relative to the upper end in the direction close to the rear bracket 304, so that the telescopic mechanism 4 is inclined as a whole. With such a setting, when the telescopic mechanism 4 is in the retracted state, the upper end of the telescopic mechanism 4 supports the mixing container 1 at the rear side of the bracket, avoiding the mixing container 1 from shaking around the bracket during the grain moistening process and ensuring the stability of the mixing container 1; when the telescopic mechanism 4 switches from the retracted state to the extended state, it will push the mixing container 1 to rotate forward around the bracket, so that the material opening of the mixing container 1 faces downward, so as to realize the automatic discharging of the mixing container 1; after the discharging is completed, the telescopic mechanism 4 retracts and resets, and the material opening of the mixing container 1 can face upward again to prepare for the next grain moistening.

[0059] In some other embodiments not shown in the figures, the first state may be the extended state, and the second state may be the retracted state. In this case, the telescopic mechanism 4 is inclined as a whole and arranged on the front side of the left and right brackets, and the lower end of the telescopic mechanism 4 is offset forward. And in the extended state, the telescopic mechanism 4 makes the material opening of the mixing container 1 face upward, and when the telescopic mechanism 4 retracts inward, it can pull the mixing container 1 to rotate forward around the left and right brackets, so that the material opening of the mixing container 1 faces downward.

[0060] More specifically, in this embodiment, the telescopic mechanism 4 can be an electric push rod, a hydraulic push rod, a pneumatic push rod, etc.

[0061] Further, referring to Figure 3 , in this embodiment, two telescopic mechanisms 4 are provided, and the two telescopic mechanisms 4 are oppositely arranged on both sides of the mixing container 1. With such a setting, by driving the rotation and reset of the mixing container 1 synchronously by the two telescopic mechanisms 4, the rotation stability of the mixing container 1 can be better.

[0062] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0063] The above embodiments only express several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
