Description

Technical Field

[0001] This utility model relates to the technical field of brewing equipment, and more specifically, to an automatic koji powder dispensing cart. Background Technology

[0002] In the brewing process, the process of spreading koji (fermented starter culture) after the grains are spread is a crucial step. Currently, the industry generally uses manual koji spreading, which has many drawbacks. On the one hand, manual koji spreading is a high-intensity physical labor, requiring operators to repeat the action for extended periods, resulting in extremely high labor intensity. Furthermore, manual operation makes it difficult to ensure the uniform distribution of koji powder on the surface of the grains, directly affecting the subsequent fermentation effect and brewing quality. On the other hand, when spreading koji manually, the powder is easily scattered everywhere, not only wasting the powder and increasing production costs, but also potentially spreading into the work environment and affecting the health of the operators.

[0003] To address the problems associated with manual koji spreading, electrically driven koji spreading carts have emerged on the market. These carts are typically powered by cables or batteries. However, cable power supply presents challenges due to the inconvenience of cable dragging. In the complex environment of production workshops, cables are prone to tangling and dragging, limiting the equipment's range of movement. Battery power supply faces the problem of insufficient battery life, leading to frequent charging that impacts production efficiency. Furthermore, the limited battery life increases equipment maintenance costs. In addition, the existing koji spreading carts have an inadequate overall structural design, making the equipment bulky and resulting in a high failure rate and high maintenance costs. More importantly, when the cart moves on the surface of the fermented grains, the wheels exert significant pressure, causing the grains to become compacted and glutinous. This compacted and glutinous grains easily adhere to the wheel hubs, affecting not only the cart's normal operation but also damaging the loose structure of the grains, which is detrimental to the growth and metabolism of microorganisms during subsequent fermentation. Utility Model Content

[0004] The present invention aims to provide an automatic koji powder spreading cart to solve the problems of high manual labor intensity, uneven koji spreading, koji powder flying everywhere, large koji powder waste, and the easy sticking and pressing of lees by the koji spreading cart in the prior art.

[0005] The embodiments of this utility model are implemented as follows:

[0006] This utility model embodiment provides an automatic koji powder spreading handcart, which includes a hopper;

[0007] The bottom sides of the hopper are respectively provided with a first plate-shaped hub and a second plate-shaped hub, which are rotatably connected to the bottom sides of the hopper.

[0008] The bottom of the hopper is provided with a discharge elongated hole, and the outside of the discharge elongated hole is provided with a control component for adjusting the amount of material to be discharged.

[0009] In use, the staff pushes the funnel on the fermented grains after spreading the grains, causing the first and second plate-shaped hubs to roll on the fermented grains, thereby driving the hopper to move. During the movement of the hopper, the staff can adjust the amount of material to be sprinkled according to the required amount of material to be sprinkled by operating the control components. The koji powder inside the hopper will be evenly sprinkled on the fermented grains through the discharge elongated hole.

[0010] The automatic koji powder spreading cart disclosed in this embodiment reduces the force-bearing area by setting the aforementioned first and second plate-shaped hubs, thus preventing excessive lees from sticking to the first and second plate-shaped hubs. At the same time, the aforementioned control components are set to control the spreading flow rate, thereby making the automatic koji powder spreading cart have the beneficial effects of low labor intensity, uniform koji spreading, koji powder not easily flying, high koji powder utilization rate, and the spreading cart not easily sticking to the glutinous rice lees.

[0011] Optionally, the outer surfaces of both the first and second plate-shaped hubs are toothed.

[0012] This configuration reduces the amount of pressure exerted on the lees by the first and second plate-shaped hubs during their movement on the lees, thus reducing the amount of lees adhering to the first and second plate-shaped hubs.

[0013] Optionally, the first and second plate-shaped hubs are provided with a plurality of fan-shaped holes in their internal radial directions, and the plurality of fan-shaped holes penetrate the first and second plate-shaped hubs, and the plurality of fan-shaped holes are evenly distributed on the first and second plate-shaped hubs.

[0014] With this design, the aforementioned fan-shaped holes effectively reduce the weight of the first and second plate-shaped hubs, while also preventing excessive lees from adhering to them.

[0015] Optionally: The hopper has a first side plate and a second side plate, the first side plate and the second side plate are symmetrically distributed, one end of the first side plate and the second side plate has a front baffle and a front inclined plate, the front baffle and the front inclined plate are fixedly connected to each other, and the two ends of the front baffle and the front inclined plate are respectively welded to one end of the first side plate and the second side plate.

[0016] The other end of the first side plate and the second side plate has a rear baffle and a rear inclined plate, the rear baffle and the rear inclined plate are fixedly connected to each other, and the two ends of the rear baffle and the rear inclined plate are respectively welded to the other end of the first side plate and the second side plate.

[0017] This configuration, consisting of the first side plate, the second side plate, the front baffle, the front inclined plate, the rear baffle, and the rear inclined plate forming a funnel-like rectangular body, facilitates filling with koji powder. At the same time, the front and rear inclined plates allow the koji powder to easily slide and accumulate at the bottom of the hopper, thus facilitating the spreading of koji.

[0018] Optionally, a first handle and a second handle are welded to the top of the hopper, and the first handle and the second handle are parallel to each other and spaced apart on the side of the rear baffle away from the front baffle.

[0019] This configuration makes it easier for workers to push the hopper, facilitating material distribution during its movement. Furthermore, the design of the first and second handles makes it easier and less strenuous for operators to push the hopper.

[0020] Optionally, a discharge orifice plate is detachably connected to the above-mentioned discharge elongated orifice, and the discharge orifice plate has several holes.

[0021] With this configuration, uniform material distribution can be achieved through the aforementioned holes on the discharge plate.

[0022] Optionally: the control component has a flow regulating baffle that is slidably attached to the outer wall of the discharge orifice plate;

[0023] The flow regulating baffle has a first hinge seat and a second hinge seat on the side near the rear baffle. A first support member and a second support member are fixedly connected to the rear inclined plate. A rotatable rotating rod is connected between the first support member and the second support member. A third hinge seat and a fourth hinge seat are provided in the radial direction of the rotating rod.

[0024] A first hinge piece is hinged between the first hinge seat and the third hinge seat, and a second hinge piece is hinged between the middle parts of the second hinge seat and the fourth hinge seat.

[0025] The end of the fourth hinge seat is hinged to a connecting rod, and the rear baffle is fixedly connected to a fifth hinge seat. The end of the fifth hinge seat is hinged to a lifting member, and the lifting member has a side rod in the radial direction. The outer end of the side rod is hinged to the end of the connecting rod near the fifth hinge seat.

[0026] With this configuration, when the material flow rate needs to be reduced, lifting the lifting member will lift the connecting rod, which will then pull the rotating rod to rotate counterclockwise. During rotation, the third and fourth hinge seats on the rotating rod will pull the flow regulating baffle to slide via the first and second hinge plates. The material flow rate is controlled by controlling the number of holes blocked by the flow regulating baffle. When the material flow rate needs to be increased, pressing down the lifting member will push the connecting rod, which will then push the rotating rod to rotate clockwise. During rotation, the third and fourth hinge seats on the rotating rod will push the flow regulating baffle to slide via the first and second hinge plates, exposing more holes on the discharge orifice plate. The material flow rate is controlled by controlling the number of holes exposed by the flow regulating baffle.

[0027] Optionally: the end of the fifth hinge seat has a toothed disc, the lifting member is hinged and clamped on the toothed disc, the end of the lifting member away from the toothed disc has a rotating torque, the side of the rotating torque near the toothed disc has a locking rod, and the end of the locking rod away from the rotating torque is movably limited on the teeth of the toothed disc.

[0028] With this configuration, when the lifting component rotates along the toothed disc to the appropriate position, the locking rod is engaged on the tooth of the toothed disc by twisting the rotation knob, thereby locking the feeding flow rate. This allows the hopper to maintain the current feeding flow rate, and thus ensures that the automatic koji powder feeding cart feeds koji evenly on the lees.

[0029] Optionally, a limiting rod is provided on the upper part of the fifth hinge seat, and the limiting rod is perpendicular to the axial direction of the fifth hinge seat.

[0030] With this configuration, the limiting rod can restrict the rotation angle of the lifting component, preventing the flow regulating baffle from being pulled out.

[0031] Optionally: The inner side of the discharge orifice plate is provided with a reinforcing plate, the reinforcing plate is fixed on the inner bottom wall of the hopper, and a first bearing and a second bearing are respectively connected to both sides of the reinforcing plate. A first rotating shaft is connected between the first plate-shaped hub and the first bearing. One end of the first rotating shaft is fixedly connected to the first plate-shaped hub, and the other end of the first rotating shaft is fixedly connected to the inner ring of the first bearing.

[0032] A second rotating shaft is connected between the second plate-shaped hub and the second bearing. One end of the second rotating shaft is fixedly connected to the second plate-shaped hub, and the other end of the second rotating shaft is fixedly connected to the inner ring of the second bearing.

[0033] Several angle steels are fixedly connected to the outer walls of the first bearing and the second bearing. The angle steels extend along the axial direction of the first bearing and the second bearing, and are evenly distributed along the circumference of the first bearing and the second bearing.

[0034] With this configuration, the first bearing and the second bearing are arranged so that the first plate-shaped hub and the first bearing rotate synchronously, and the second plate-shaped hub and the second bearing rotate synchronously, thereby making the first plate-shaped hub and the second plate-shaped hub rotate asynchronously, which facilitates the turning of the cart. The angle steels serve to clear the koji powder to prevent it from bridging and to evenly spread the koji powder on the lees.

[0035] Optionally: The bottom of the outer walls of the first side plate and the second side plate are respectively fixedly connected with a first arc-shaped piece and a second arc-shaped piece;

[0036] The inner side of the first arc-shaped piece is fixedly connected with a first guide piece and a second guide piece, and the first guide piece and the second guide piece have a first groove between them and the outer wall of the front inclined plate and the rear inclined plate.

[0037] The inner side of the second arc-shaped piece is fixedly connected with a third guide piece and a fourth guide piece, and the third guide piece and the fourth guide piece have a second sliding groove between them and the outer wall of the front inclined plate and the rear inclined plate.

[0038] The two ends of the aforementioned flow regulating baffle are slidably connected to the grooves of the first and second slide grooves, respectively.

[0039] With this configuration, the flow regulating baffle is supported by the first guide plate, the second guide plate, the third guide plate, and the fourth guide plate, making it easy for the flow regulating baffle to slide along the groove direction of the first and second slide grooves.

[0040] In summary, the automatic koji powder spreading cart disclosed in this utility model has the advantages of low labor intensity, uniform koji spreading, less koji powder flying away, high koji powder utilization rate, and less sticking to the koji spreading cart and pressing glutinous rice wine lees.

Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0054] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0055] Example

[0056] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 This embodiment proposes an automatic koji powder spreading handcart, including a hopper 1;

[0057] The bottom sides of the hopper 1 are respectively provided with a first plate-shaped hub 2 and a second plate-shaped hub 3, which are rotatably connected to the bottom sides of the hopper 1.

[0058] The bottom of the hopper 1 is provided with a discharge elongated hole 4, and the outside of the discharge elongated hole 4 is provided with a control component 5 for adjusting the amount of material to be discharged.

[0059] In use, the staff pushes the funnel on the fermented grains after spreading the grains, causing the first plate hub 2 and the second plate hub 3 to roll on the fermented grains, thereby driving the hopper 1 to move. During the movement of the hopper 1, the staff can adjust the amount of material to be sprinkled according to the required amount of material to be sprinkled by operating the control component 5. The koji powder inside the hopper 1 will be evenly sprinkled on the fermented grains through the discharge elongated hole 4.

[0060] The automatic koji powder spreading cart disclosed in this embodiment has a reduced force-bearing area due to the setting of a first plate-shaped hub 2 and a second plate-shaped hub 3, which avoids excessive lees sticking to the first plate-shaped hub 2 and the second plate-shaped hub 3. At the same time, a control component 5 is set to control the spreading flow rate, thereby making the automatic koji powder spreading cart have the beneficial effects of low labor intensity, uniform spreading of koji, less koji powder flying, high koji powder utilization rate, and less sticking of glutinous rice lees on the spreading cart.

[0061] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The outer surfaces of the first plate-shaped hub 2 and the second plate-shaped hub 3 are both toothed, which reduces the crushing of the lees and the adhesion of the lees to the first plate-shaped hub 2 and the second plate-shaped hub 3 during their movement on the lees.

[0062] The first plate-shaped hub 2 and the second plate-shaped hub 3 have several fan-shaped holes 6 in their inner radial direction. The fan-shaped holes 6 all penetrate the first plate-shaped hub 2 and the second plate-shaped hub 3. The fan-shaped holes 6 are evenly distributed on the first plate-shaped hub 2 and the second plate-shaped hub 3. The fan-shaped holes 6 effectively reduce the weight of the first plate-shaped hub 2 and the second plate-shaped hub 3, and at the same time, prevent excessive lees from sticking to them.

[0063] The hopper 1 has a first side plate 7 and a second side plate 8, which are symmetrically distributed. One end of the first side plate 7 and the second side plate 8 has a front baffle 9 and a front inclined plate 10, which are fixedly connected to each other. The two ends of the front baffle 9 and the front inclined plate 10 are respectively welded to one end of the first side plate 7 and the second side plate 8. The other end of the first side plate 7 and the second side plate 8 has a rear baffle 11 and a rear inclined plate 12, which are fixedly connected to each other. The two ends of the rear baffle 11 and the rear inclined plate 12 are respectively welded to the other end of the first side plate 7 and the second side plate 8. The first side plate 7, the second side plate 8, the front baffle 9, the front inclined plate 10, the rear baffle 11 and the rear inclined plate 12 form a rectangular body similar to a funnel, which is convenient for filling with koji powder. At the same time, the setting of the front inclined plate 10 and the rear inclined plate 12 makes it easy for the koji powder to slide and accumulate at the bottom of the hopper 1, which facilitates the spreading of koji.

[0064] The top of the hopper 1 is welded with a first handle 13 and a second handle 14. The first handle 13 and the second handle 14 are parallel to each other and spaced apart on the side of the rear baffle 11 away from the front baffle 9. The first handle 13 and the second handle 14 make it easier for the operator to push the hopper 1 and facilitate the hopper 1 to scatter material during the movement. At the same time, the setting of the first handle 13 and the second handle 14 makes it easier and less strenuous for the operator to push the hopper 1.

[0065] A discharge orifice plate 15 is detachably connected to the discharge orifice 4. The discharge orifice plate 15 has several holes 16, which can be used to achieve uniform material spreading.

[0066] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The control component 5 has a flow regulating baffle 17, which is slidably attached to the outer wall of the discharge orifice plate 15.

[0067] The flow regulating baffle 17 has a first hinge seat 18 and a second hinge seat 19 on the side near the rear baffle 11. A first support member 20 and a second support member 21 are fixedly connected to the rear inclined plate 12. A rotatable rotating rod 22 is connected between the first support member 20 and the second support member 21. The rotating rod 22 has a third hinge seat 23 and a fourth hinge seat 24 in the radial direction.

[0068] A first hinge piece 25 is hinged between the first hinge seat 18 and the third hinge seat 23, and a second hinge piece 26 is hinged between the middle part of the second hinge seat 19 and the fourth hinge seat 24.

[0069] The end of the fourth hinge seat 24 is hinged to a connecting rod 27. A fifth hinge seat 28 is fixedly connected to the rear baffle 11. The end of the fifth hinge seat 28 is hinged to a lifting member 29. The lifting member 29 has a side rod 30 in its radial direction. The outer end of the side rod 30 is hinged to the end of the connecting rod 27 near the fifth hinge seat 28. When it is necessary to reduce the material flow rate, by pulling the lifting member 29, the lifting member 29 will lift the connecting rod 27. The connecting rod 27 will pull the rotating rod 22 to rotate counterclockwise. During the rotation, the third hinge seat 23 and the fourth hinge seat 24 on the rotating rod 22 will pass through the first hinge piece 25 and the second hinge piece 26. Pull the flow regulating baffle 17 to slide, and control the number of holes 16 blocked by the flow regulating baffle 17 to control the material dispensing flow. When it is necessary to increase the material dispensing flow, press down the lifting member 29. The lifting member 29 will push the connecting rod 27. The connecting rod 27 will push the rotating rod 22 to rotate clockwise. During the rotation, the third hinge seat 23 and the fourth hinge seat 24 on the rotating rod 22 will push the flow regulating baffle 17 to slide through the first hinge piece 25 and the second hinge piece 26, so that the flow regulating baffle 17 exposes more holes 16 on the discharge orifice plate 15. The material dispensing flow is controlled by controlling the number of holes 16 exposed by the flow regulating baffle 17.

[0070] The fifth hinge seat 28 has a toothed disc 31 at its end. The lifting member 29 is hinged and clamped on the toothed disc 31. The end of the lifting member 29 away from the toothed disc 31 has a rotating knob 32. The side of the rotating knob 32 near the toothed disc 31 has a locking rod (not shown in the figure). The end of the locking rod away from the rotating knob 32 is movably limited on the teeth of the toothed disc 31. When the lifting member 29 rotates along the toothed disc 31 to a suitable position, the rotating knob 32 is twisted to lock one end of the locking rod on the teeth of the toothed disc 31, thereby locking the feeding flow rate. This makes it easier for the hopper 1 to maintain the current feeding flow rate, and thus ensures that the automatic feeding powder handcart keeps the feeding of yeast even when feeding yeast on the lees.

[0071] The upper part of the fifth hinge seat 28 is provided with a limiting rod 33. The limiting rod 33 is perpendicular to the axial direction of the fifth hinge seat 28. The limiting rod 33 can limit the rotation angle of the lifting member 29 and prevent the flow regulating baffle 17 from being pulled out.

[0072] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10A reinforcing plate 34 is provided on the inner side of the discharge orifice plate 15. The reinforcing plate 34 is fixed to the inner bottom wall of the hopper 1. A first bearing 35 and a second bearing 36 are respectively connected to both sides of the reinforcing plate 34. A first rotating shaft 37 is connected between the first plate-shaped hub 2 and the first bearing 35. One end of the first rotating shaft 37 is fixedly connected to the first plate-shaped hub 2, and the other end of the first rotating shaft 37 is fixedly connected to the inner ring of the first bearing 35. A second rotating shaft 38 is connected between the second plate-shaped hub 3 and the second bearing 36. One end of the second rotating shaft 38 is fixedly connected to the second plate-shaped hub 3, and the other end of the second rotating shaft 38 is fixedly connected to the inner ring of the second bearing 36. Several angle steels 39 are fixedly connected to the outer walls of the first bearing 35 and the second bearing 36. The angle steels 39 extend along the axial direction of the first bearing 35 and the second bearing 36, and are evenly distributed along the circumference of the first bearing 35 and the second bearing 36. The arrangement of the first bearing 35 and the second bearing 36 allows the first plate-shaped hub 2 and the first bearing 35 to rotate synchronously, and the second plate-shaped hub 3 and the second bearing 36 to rotate synchronously. This makes the first plate-shaped hub 2 and the second plate-shaped hub 3 rotate asynchronously, which facilitates the turning of the cart. The angle steels 39 also serve to clear the koji powder to prevent it from bridging and to evenly sprinkle the koji powder on the lees.

[0073] The bottom of the outer walls of the first side plate 7 and the second side plate 8 are respectively fixedly connected to a first arc-shaped piece 40 and a second arc-shaped piece 41; the inner side of the first arc-shaped piece 40 is fixedly connected to a first guide piece 42 and a second guide piece 43, and the first guide piece 42 and the second guide piece 43 have a first groove (not shown in the figure) between them and the outer walls of the front inclined plate 10 and the rear inclined plate 12; the inner side of the second arc-shaped piece 41 is fixedly connected to a third guide piece 44 and a fourth guide piece 45, and the third guide piece 44 and the fourth guide piece 45 have a second groove (not shown in the figure) between them and the outer walls of the front inclined plate 10 and the rear inclined plate 12; the two ends of the flow regulating baffle 17 are respectively slidably connected in the grooves of the first groove and the second groove, so that the flow regulating baffle 17 is supported by the first guide piece 42, the second guide piece 43, the third guide piece 44 and the fourth guide piece 45, which facilitates the flow regulating baffle 17 to slide along the grooves of the first groove and the second groove.

[0074] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 In this embodiment, the first rotating shaft 37 and the second rotating shaft 38 are coaxial but do not rotate synchronously, so that the first plate-shaped hub 2 and the second plate-shaped hub 3 rotate independently, which makes it easy to maintain uniform material spreading when the trolley turns.

[0075] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The specific operating principle of the automatic koji powder spreading cart in this embodiment is as follows: During operation, the hopper 1 is filled with koji powder. The spreading cart is pushed by the first handle 13 and the second handle 14. The spreading cart, filled with koji powder, rotates the first plate-shaped hub 2 and the second plate-shaped hub 3 under manual pushing, utilizing the friction of the ground. Because the first plate-shaped hub 2 and the second plate-shaped hub 3 are thin and have a toothed circumference, they reduce the crushing of the lees during movement on the lees, reducing the adhesion of lees to the first plate-shaped hub 2 and the second plate-shaped hub 3 of the spreading cart. Hub 2 and the second plate-shaped hub 3 drive the first rotating shaft 37 and the second rotating shaft 38 to rotate, thereby evenly spreading the koji powder in the hopper 1 through the holes 16 of the discharge orifice plate 15 onto the lees spread on the ground. At the same time, when the first plate-shaped hub 2 and the second plate-shaped hub 3 drive the first rotating shaft 37 and the second rotating shaft 38 to rotate, they also help to clear the koji powder and prevent it from bridging, making it easier to spread the koji powder evenly on the lees. The koji spreading flow rate is controlled by adjusting how much the flow regulating baffle 17 blocks the holes 16 of the discharge orifice plate 15, thereby completing the koji spreading operation for brewing.

[0076] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
