Description

Technical Field

[0001] The utility model belongs to the technical field of grain drying equipment, and in particular relates to high-temperature rice cooling equipment. Background Art

[0002] When rice is harvested, it often encounters rainy weather, which often causes excessive moisture. If it is not dried in time, it is very easy to cause the temperature to rise, mold and sprout, resulting in losses. At present, the commonly used cooling methods are natural drying and mechanical drying. Natural drying is restricted by weather conditions and cannot be dried on rainy days; mechanical drying, due to the high moisture and high temperature of rice, has extremely poor fluidity, which can easily cause drying equipment to be blocked, the drying is relatively uneven, and the drying effect cannot be guaranteed.

[0003] And in the traditional impeller grain discharge wheel mechanism for granaries, the grain discharge gap, the gap between the upstream grain plate with a movable and adjustable adjusting slat at the end and the rotating discharge impeller, its space size is related to the size of the dried particles, and the discharge amount can be precisely adjusted and controlled by reasonably controlling the grain discharge gap. However, the existing adjustable impeller grain discharge mechanism, such as the gap-adjustable impeller grain discharge mechanism for a grain dryer disclosed in the patent with application number 201420709512.0, requires continuous manual screwing of bolts to adjust the fixed and tilted position between the adjusting slat and the grain flow plate, which is time-consuming and labor-intensive, cumbersome to operate, and has limited adjustment accuracy, thereby affecting the efficiency and precise control of the discharge.

[0004] In addition, the power transmission mechanism combined with the grain discharge wheel, such as chain transmission, is prone to broken teeth or chains if there is a heavy load during use. Although the grain discharge wheel installation mechanism disclosed in patent CN212320369U can realize the up and down movement adjustment of the grain discharge wheel to avoid this situation, the structure needs to continuously screw the installation screws during operation, and the position of the corresponding screw holes is fixed. This adjustment method is not only time-consuming and labor-intensive, but also has low accuracy and is difficult to meet the needs of precise adjustment, which brings inconvenience to the position adjustment of the grain discharge wheel in the grain discharge gap.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The high-temperature rice cooling equipment provided by the utility model has uniform ventilation and cooling. Since the rice flows from top to bottom, each part of the grain passes through the same air distribution structure, so each part of the grain can be evenly cooled. Since the air volume is adjustable, the air volume can be adjusted according to the different heating conditions of the rice to improve the cooling efficiency and reduce the grain to a reasonable temperature at one time. Due to the continuous feeding and unloading production without stopping in the middle, the efficiency is relatively high. Considering the poor fluidity of high-temperature and high-moisture rice, a larger angle tube spacing is designed to avoid grain stagnation and blockage, and the cooling effect is good. It also has the following advantages:

[0015] Efficient cooling: The outside air is introduced through the blower, and the air flow in the bin is realized through the setting of the air inlet angle pipe and the exhaust angle pipe, which takes away the heat and effectively reduces the temperature of the rice.

[0016] Flexible adjustment: The design of the discharge adjustment mechanism allows the horizontal screw and the middle axis to be adjusted by the side hand wheel, thereby changing the angle between the grain flow plates and the discharge space, achieving precise control of the rice flow speed and direction.

[0017] Structural safety: The cross screw is designed with a limited end shaft to ensure that the middle shaft will not fall out of the cross screw, enhancing the safety and reliability of the mechanism.

[0018] Material handling efficiency: The discharging transmission mechanism controls the speed and torque of the grain discharging wheel through the cooperation of the reduction motor, driven wheel and auxiliary gear, thereby improving the efficiency and accuracy of grain discharging.

[0019] Low maintenance cost: The design of the equipment reduces maintenance costs and failure rates. Due to the stability of the transmission mechanism and the design of load sharing, the risk of chain breakage or chain breakage is reduced.

[0020] Improved storage quality: Through effective cooling and discharge control, the impact of high temperature on rice quality is reduced and the storage quality of rice is improved.

[0021] Avoid stagnation and blockage: The larger angular tube spacing design takes into account the poor fluidity of high-moisture rice and avoids grain stagnation and blockage.

[0022] Easy to operate: The design of the auxiliary adjustment mechanism makes the up and down movement of the grain discharge wheel more flexible, which is convenient for on-site operation and maintenance.

[0023] Load protection: The coordinated design of the spring and drive rod in the auxiliary adjustment mechanism can protect the chain by skipping teeth when the load is too large, avoiding broken teeth or chains.

[0024] Strong adaptability: The equipment can be adjusted according to actual storage needs and the characteristics of rice, and has strong adaptability and flexibility.

[0025] Reduce losses: By precisely controlling the discharge speed and direction, the quality degradation and loss of rice caused by high temperature are reduced.

[0026] Improve operational convenience: The design of the auxiliary adjustment mechanism provides convenience for chain installation and improves the efficiency of the entire mechanism adjustment operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0034] See also Figure 1-5 The utility model provides a technical solution for high-temperature rice cooling equipment: Example

[0035] The present embodiment provides a high-temperature rice cooling device, including a bin body 1, a discharge adjustment mechanism 4, an auxiliary adjustment mechanism 12, a discharge transmission mechanism 5 and a ventilation mechanism. A feed inlet is provided at the top of the bin body, a discharge port 6 is provided at the bottom, and the ventilation mechanism is fixedly installed inside the bin body.

[0036] like Figure 1-2 As shown, the ventilation mechanism includes an air intake angle tube 2 and an exhaust angle tube 3. Each air intake angle tube has the same structure as the exhaust angle tube, with a conical top and an open bottom. They are evenly staggered and installed in the inner cavity of the warehouse in a crisscross pattern from top to bottom. For example, an exhaust angle tube is installed between two adjacent air intake angle tubes. Further, one end of each air intake angle tube 2 is connected to the air duct group 7 outside the warehouse, and the other end is fixedly closed to the inner wall of the warehouse. The open end of the air duct group is connected to the blower 8. By driving the blower to work, the outside air can enter the air duct group through the blower, and flow into the air intake angle tube along the extension direction of the air duct path of the air duct group. Both ends of the exhaust angle tube 3 are directly connected to the air outside the warehouse.

[0037] In this embodiment, a ventilation mechanism is arranged in the bin body, and a blower is used to control the outside air to enter the air inlet angle pipe, and then enter the bin body from the bottom of the air inlet angle pipe. The air passes through the gaps between the grains in the bin body and enters the exhaust angle pipe. The exhaust angle pipe is connected to the outside, so that the exhaust gas is discharged out of the bin body.

[0038] like Figure 1 and Figure 3 As shown, a discharge adjustment mechanism 4 is installed below the ventilation mechanism, and the discharge adjustment mechanism includes a first grain flow plate 9, a second grain flow plate 10, a right baffle 11, a transverse screw 42, a central axis 43, etc. The left end of the first grain flow plate 9 is fixed to the inside of the bin body, and the right end is tilted downward and rotatably connected to the second grain flow plate 10. A right baffle 11 is provided on the right side of the second grain flow plate, and a grain discharge space is formed between the two. A central axis 43 is fixedly inserted in the second grain flow plate, and an internal thread is machined inside the central axis 43, and an external thread 45 is machined outside the transverse screw 42, and the transverse screw thread is installed inside the central axis. One end of the transverse screw extends out of the bin body and is fixedly connected to a side handwheel 41, and the other end is provided with a limit end shaft 44. The diameter of the limit end shaft is larger than the diameter of the transverse screw, and is used to prevent the central axis from rotating out of the transverse screw when the central axis rotates on the transverse screw.

[0039] like Figure 3 and Figure 4As shown, the new discharging adjustment mechanism is arranged in this way. When the driving side hand wheel 41 is rotated, due to the cooperation between the external thread on the cross screw and the internal thread in the middle shaft, the rotation of the cross screw will drive the middle shaft to rotate on the cross screw, and then drive the second grain flow plate 10 connected thereto to rotate relative to the first grain flow plate, so that the angle between the two changes, and at the same time, the size of the discharging space between the second grain flow plate and the right baffle 11 can be adjusted, thereby changing the flow path of rice and other grains on the grain flow plate, so as to achieve the purpose of adjusting the material outflow speed and direction. At the same time, the existence of the upper limit end shaft of the cross screw ensures that the middle shaft will not escape from the cross screw, thereby ensuring the safety and reliability of the mechanism. The discharging adjustment mechanism cooperates with the grain discharge wheel in the grain discharge space, so as to realize flexible adjustment of the material outflow speed and direction, thereby improving the efficiency and flexibility of material processing, and the grain discharge space can be adjusted only by rotating the side hand wheel in the forward or reverse direction, thereby further improving the convenience of operation.

[0040] like Figure 1-3 As shown, the grain discharge wheel 53 of the discharge transmission mechanism 5 is rotatably installed in the grain discharge space on the left side of the right baffle 11 through the front and rear end auxiliary adjustment mechanisms, and the lower part of the grain discharge space is connected to the discharge port 6 at the bottom of the silo body, and the grain materials are discharged out of the silo body through the discharge port 6. The discharge transmission mechanism 5 also includes a reduction motor 51, a driven wheel 55 and an auxiliary gear 56, etc. The reduction motor is installed on the outer wall of the silo body through a motor seat 54, and the output end of the reduction motor is fixedly connected to a driving gear 52.

[0041] like Figure 3 As shown, the grain discharge sprocket 532 on the front end of the grain discharge wheel 53 extends out of the warehouse body, and a driven wheel 55 is rotatably installed on the outer wall of the warehouse body on the left side of the grain discharge sprocket 532 through a mounting seat, and an auxiliary gear 56 is rotatably installed below the grain discharge sprocket 532. A rotating shaft is installed in the auxiliary gear 56, and one end of the rotating shaft is installed on the warehouse body chassis through a bearing seat. The driving gear 52 of the reduction motor, the grain discharge sprocket 532 at the front end of the grain discharge wheel, the driven wheel 55 and the auxiliary gear 56 are all located on the same plane, and are meshed and connected with a chain 57. The transmission of the chain driven by the reduction motor drives the rotation of the grain discharge sprocket, and then cooperates with the driven wheel and the auxiliary gear to ensure that the power is smoothly transmitted between the gears, and at the same time realize the conversion of speed and torque. In addition, in actual application, the outer casing can also be fixed outside the discharge transmission mechanism to protect the transmission components and extend the service life; and the grain discharge transmission mechanism can also be set at the front and rear ends of the grain discharge wheel according to actual needs.

[0042] The discharging transmission mechanism is driven by a reduction motor to drive the chain to rotate, and at the same time, it drives the grain discharging wheel to rotate through meshing transmission with the grain discharging sprocket, thereby controlling and adjusting the speed of rotation of the grain discharging wheel and controlling the grain discharging speed to achieve a satisfactory cooling effect. The existence of the driven wheel makes the entire transmission mechanism more stable and also plays a role in sharing the load. Such a structural setting not only improves the efficiency and accuracy of grain discharging, but also reduces the maintenance cost and failure rate of the equipment.

[0043] The utility model provides a high-temperature rice cooling device. When in actual use, the high-temperature rice enters the bin body through the feed port on the top of the bin body, the blower works, and the outside air is introduced through the air inlet angular tube. The air flows in the bin body and takes away the heat, and then is discharged through the exhaust angular tube to achieve the cooling of the rice; by rotating the side hand wheel 41, adjusting the horizontal screw 42 and the middle axis 43, changing the angle between the second grain flow plate 10 and the first grain flow plate 9, and the discharge space between the second grain flow plate and the right baffle 11, the flow speed and direction of the rice are adjusted; the reduction motor 51 drives the grain discharge wheel 53 to rotate, and the auxiliary transmission of the auxiliary gear 56 and the driven wheel 55 controls the grain discharge speed to ensure that the rice is smoothly discharged from the bin body through the discharge port 6 at the bottom of the bin body, completing the entire cooling and discharge process.

[0044] The high-temperature rice cooling equipment provided by the present invention takes into account the cooling demand during the storage of rice and the problem of poor fluidity of high-temperature and high-moisture rice, and sets a larger angular tube spacing to avoid grain stagnation and blockage, achieving a good cooling effect; by accurately controlling the discharge speed and direction, as well as an effective ventilation mechanism, the storage quality of rice is improved, the quality degradation and loss caused by high temperature are reduced, and the purpose of efficient cooling is achieved.

It should be noted that in this embodiment and the accompanying drawings, the auxiliary adjustment mechanism is only installed on one side of the main body, but in actual use, the auxiliary adjustment mechanism can also be symmetrically installed on both sides according to the on-site conditions; and when the grain discharge sprocket is installed only on one side, the other end of the central shaft can be directly rotatably connected to the wheel seat 121 of the auxiliary adjustment mechanism after extending out of the warehouse body.

[0046] like Figure 5 As shown, the auxiliary adjustment mechanism includes a wheel seat 121, a carrier plate 122, a spring 123, a fixed guide sleeve 124, a guide rod 125 and a driving rod 126, etc. The carrier plate 122 is fixedly installed on the outer wall of the warehouse body, and the upper and lower outer walls of the carrier plate are respectively fixed with fixed guide sleeves 124, and the guide rod 125 is installed in the two fixed guide sleeves 124. The top of the guide rod is fixedly connected to the bottom of the wheel seat, and the guide rod between the wheel seat and the upper fixed guide sleeve is also installed with a spring 123. The guide rod between the two fixed guide sleeves is fixedly connected to the driving rod 126, and the guide rod is driven to move up and down by controlling the up and down movement of the driving rod, thereby realizing the appropriate up and down movement adjustment of the grain discharge wheel, thereby improving the flexibility of the adjustment operation of the entire mechanism, the structure is simple and easy to operate, and provides convenience for the operation of installing the chain. After adjusting to the appropriate position, the position of the driving rod can be restricted and fixed by installing lock wires on the upper and lower sides of the driving rod. In addition, the auxiliary adjustment mechanism can also jump teeth when the load is too large, thereby protecting the chain and avoiding the occurrence of broken teeth or broken chains.
