Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering technology, and in particular to a crop dryer for saline-alkali land with adjustable wind speed. Background Technology

[0002] In saline-alkali land agriculture, post-harvest dehydration is a crucial step affecting quality preservation. Traditional methods of drying crops in saline-alkali land mainly rely on natural sun-drying, which has the following prominent problems: First, the strong sunlight and high humidity in saline-alkali areas result in low efficiency of natural sun-drying, typically requiring 5-7 days to reach a safe moisture content; second, during open-air drying, salt on the crop surface crystallizes as moisture evaporates, leading to secondary pollution; and third, frequent turning and drying is labor-intensive and makes it difficult to ensure uniform drying.

[0003] While some rotary drying equipment that has emerged in recent years has improved drying uniformity, it still suffers from problems such as high energy consumption and poor adaptability. In particular, in saline-alkali areas with weak power infrastructure, high-power equipment is difficult to promote and apply. In addition, the speed control system of existing equipment mostly adopts electronic control, which is prone to circuit corrosion failure in the high humidity and high salt environment of saline-alkali land, resulting in high maintenance costs. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a crop dryer for saline-alkali land with adjustable wind speed, so as to solve the problems of uneven drying, high salt residue and high energy consumption of traditional dryers.

[0005] To achieve the above objectives, this utility model provides a multi-speed adjustable crop air dryer for saline-alkali land, comprising: a housing, a blower installed on one side of the housing, and a plurality of air outlet pipes fixedly installed at one end of the housing;

[0006] A rotating assembly, installed inside the housing, is used to adjust the crop angle;

[0007] A speed control component is installed on one side of the housing and is used to adjust the wind speed.

[0008] Preferably, the rotating assembly includes a rotating column rotatably mounted inside the housing, a plurality of bearing plates mounted on the rotating column, a plurality of perforations formed on the bearing plates, a gear fixedly mounted on the rotating column, a plurality of through holes formed on one side of the housing, a rotating shaft rotatably mounted on both sides of the housing near the gear, a rack slidably mounted on the rotating shaft, and the rack meshing with the gear.

[0009] Preferably, rotating seats are symmetrically fixedly installed on both sides of the housing, and a rotating shaft is rotatably installed between the two rotating seats. A sliding sleeve is slidably installed on the rotating shaft. A connecting column is fixedly installed at one end of the sliding sleeve, and a rack is fixedly installed at the end of the connecting column away from the sliding sleeve. A sliding groove is opened on the rotating shaft, and the sliding sleeve is slidably installed on the sliding groove.

[0010] Preferably, a concentrator is fixedly installed on the side of the through hole near the rotating column, the rotating shaft passes through the concentrator, and a plurality of fan blades are fixedly installed on the rotating shaft, the fan blades being arranged within the space enclosed by the concentrator.

[0011] Preferably, a plurality of fixing plates are installed inside the housing, and slide rails are provided inside the fixing plates, with the bearing plate installed inside the slide rails.

[0012] Preferably, the speed regulating component includes a speed regulating shell installed on one side of the housing, mounting plates are installed at both ends of the speed regulating shell, a plurality of air regulating plates are movably installed between the two mounting plates, a handwheel is fixedly installed on one side of the speed regulating shell, a steel wire is installed at one end of the handwheel, a plurality of air regulating plates are installed on the steel wire at equal intervals, and an air blowing port is opened on one side of the housing, the air blowing port being adapted to the speed regulating shell.

[0014] Preferably, a guide tube is fixedly installed at one end of the speed regulating housing, and the steel wire passes through the guide tube and extends therethrough.

[0015] The beneficial effects of this utility model are:

[0016] 1. This multi-speed adjustable saline-alkali land crop air dryer, through the setting of a rotating component, rotating column, bearing plate and gear transmission mechanism to form a linkage rotation system, part of the airflow generated by the blower directly dries the crops, and the other part drives the fan blades to drive the rotating shaft to rotate. Through the meshing transmission of rack and pinion, the bearing plate rotates at a uniform speed. This structure can realize the automatic flipping of crops during the air drying process, ensuring that all surfaces are evenly air-dried, avoiding the problem of uneven drying caused by traditional fixed air drying, effectively improving the air drying efficiency and quality of saline-alkali land crops, while reducing the quality decline caused by uneven salt crystallization.

[0017] 2. This multi-speed adjustable crop dryer for saline-alkali land features a speed-regulating component. A precise wind speed adjustment system is constructed via a handwheel, a steel wire linkage mechanism, and adjustable wind vanes.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0031] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] like Figures 1 to 9 As shown, a multi-speed adjustable crop dryer for saline-alkali land includes: a housing 1, a blower 2 installed on one side of the housing 1, and several air outlet pipes 3 fixedly installed at one end of the housing 1; a rotating assembly installed inside the housing 1, which is used to adjust the crop angle; and a speed regulating assembly installed on one side of the housing 1, which is used to adjust the wind speed.

[0033] When the equipment is started, the operator first places the crops to be treated in the saline-alkali soil evenly inside the housing 1, and then turns on the blower 2. The high-speed airflow generated by the blower 2 enters the housing 1 through the pipe to form a uniform airflow field. Under the action of the airflow, the rotating component automatically starts, converting the air kinetic energy into mechanical rotational force, driving the crop fixing frame to rotate at a uniform speed, ensuring that all surfaces of the crops are evenly contacted by the airflow. At the same time, the operator can adjust the speed control component according to the crop type and moisture content. The whole system, through the synergistic effect of airflow drive and wind speed regulation, ensures drying efficiency while avoiding damage to the crop surface caused by excessive wind speed. Especially for the characteristics of high salt content and easy crystallization of crops in saline-alkali soil, a low-speed, high-volume drying mode is adopted, which effectively removes surface moisture and prevents salt leaching and secondary pollution. Ultimately, it achieves efficient, uniform, and low-damage drying of crops in saline-alkali soil, with a significant improvement in drying efficiency compared to traditional natural sun drying.

[0034] like Figures 2 to 4 As shown, the rotating assembly includes a rotating column 5 rotatably mounted inside the housing 1, several bearing plates 6 mounted on the rotating column 5, several perforated holes 7 on the bearing plates 6, a gear 10 fixedly mounted on the rotating column 5, several through holes 20 on one side of the housing 1, a rotating shaft 14 rotatably mounted on both sides of the housing 1 near the gear 10, a rack 11 slidably mounted on the rotating shaft 14, the rack 11 meshing with the gear 10; rotating seats 13 are symmetrically fixedly mounted on both sides of the housing 1, a rotating shaft 14 rotatably mounted between the two rotating seats 13, and a sliding sleeve slidably mounted on the rotating shaft 14. 19. A connecting column 18 is fixedly installed at one end of the sliding sleeve 19, and a rack 11 is fixedly installed at the end of the connecting column 18 away from the sliding sleeve 19. A groove 15 is provided on the rotating shaft 14, and the sliding sleeve 19 is slidably installed on the groove 15. A concentrator 12 is fixedly installed on the side of the through hole 20 near the rotating column 5. The rotating shaft 14 passes through the concentrator 12, and several fan blades 17 are fixedly installed on the rotating shaft 14. The fan blades 17 are arranged in the space enclosed by the concentrator 12. Several fixing plates 8 are installed inside the housing 1. A slide rail 9 is provided inside the fixing plate 8, and a bearing plate 6 is installed in the slide rail 9.

[0035] When the equipment is running, the operator first opens the sealed door of the housing 1 and evenly places the crops to be treated on the bearing plate 6. The bearing plate 6 achieves stable support through the precise cooperation between the slide rail 9 and the fixed plate 8. After the blower 2 is started, the generated high-speed airflow is divided into two working paths: the main airflow is directly introduced into the housing 1 after being adjusted by the speed regulating component to form a drying airflow, while the auxiliary airflow is concentrated to impact the fan blade 17 through the guiding effect of the air concentrator 12. Driven by the kinetic energy of the airflow, the fan blade 17 drives the rotating shaft 14 to rotate. The rotating shaft 14 converts the rotational motion into the axial reciprocating motion of the sliding sleeve 19 through the sliding cooperation between the slide groove 15 and the sliding sleeve 19. The sliding sleeve 19 pushes the rack 11 to perform synchronous reciprocating motion through the connecting column 18. The meshing transmission between the rack 11 and the gear 10 converts the linear motion into the rotational motion of the rotating column 5, thereby driving all the bearing plates 6 to rotate. The axis of column 5 rotates at a uniform speed. During this process, the opening of the perforation 7 ensures that the crop is fixed and stable while allowing airflow to penetrate, realizing three-dimensional air drying of the crop. The tapered structure of the converging air duct 12 significantly increases the airflow speed and enhances the driving torque on the fan blade 17. At the same time, the rotating seat 13 provides support for the rotating shaft 14, ensuring smooth transmission. By adjusting the main airflow speed through the speed regulating component, the intensity of the auxiliary airflow can be changed simultaneously, thereby achieving adaptive matching between the rotation speed and the air drying intensity. The rotating component and the speed regulating component use the split airflow to simultaneously complete the crop turning drive and drying treatment, which not only improves the energy utilization rate, but also ensures the synchronous removal of salt crystals on the surface of saline-alkali crops through uniform turning, ultimately achieving the effect of reducing moisture content. The entire system does not require an additional power source and achieves automated operation solely through airflow energy conversion, significantly improving the efficiency and quality of saline-alkali crop air drying treatment.

[0036] like Figures 5 to 9 As shown, the speed control assembly includes a speed control shell 4 installed on one side of the housing 1. Mounting plates 25 are installed at both ends of the speed control shell 4. Several air regulating plates 29 are movably installed between the two mounting plates 25. A handwheel 22 is fixedly installed on one side of the speed control shell 4. A steel wire 23 is installed at one end of the handwheel 22. Several air regulating plates 29 are installed at equal intervals on the steel wire 23. An air outlet 21 is opened on one side of the housing 1, and the air outlet 21 is adapted to the speed control shell 4. A central shaft 27 and an outer shaft 28 are fixedly installed between the two mounting plates 25. Several rotating shafts 30 are rotatably installed at equal intervals on the central shaft 27. One end of each rotating shaft 30 is slidably connected to the outer shaft 28, and the other end is fixedly connected to the steel wire 23. A guide tube 24 is fixedly installed at one end of the speed control shell 4, and the steel wire 23 passes through the guide tube 24 and extends therefrom.

[0037] When the drying air speed needs to be adjusted, the operator turns the handwheel 22. The handwheel 22 drives all the air regulating plates 29 to move synchronously via the steel wire 23. The steel wire 23 moves smoothly under the guidance of the guide tube 24, allowing the air regulating plates 29 to adjust their angle around the central axis 27. The air regulating plates 29 are slidably connected to the outer shaft 28 via the rotating shaft 30, ensuring that the opening and closing angles of all the air regulating plates 29 are completely consistent. When the angle of the air regulating plate 29 changes, the effective ventilation area of ​​the air outlet 21 changes accordingly, thereby precisely controlling the airflow rate entering the housing 1. This speed regulation mechanism adopts a steel wire linkage setting, and all speed regulating plates can be controlled by a single point. The wind regulating plate 29 is synchronously adjusted; the guide pipe 24 effectively prevents the steel wire 23 from deviating; the rigid frame composed of the mounting plate 25 and the central shaft 27 provides stable support for the wind regulating plate 29, ensuring that it will not deform during long-term use; when the opening of the wind regulating plate 29 decreases, the airflow forms a vortex acceleration effect in the speed regulating shell 4, which not only ensures the linearity of wind speed regulation but also avoids the impact of sudden airflow on crops; the entire speed regulating component has a compact structure and sensitive response. Operators only need to rotate the handwheel 22 to accurately control the drying intensity, which is particularly suitable for the differentiated wind speed requirements of crops in saline-alkali land at different moisture content stages, realizing energy-saving and efficient drying process control.
