Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an intelligent grain loading machine equipped with a grain leveling device. Background Technology

[0002] As a specialized grain storage equipment, the grain loading machine is mainly used to achieve efficient transfer and uniform distribution of grain from the conveyor system into the grain silo. Its core function is accomplished by an inclined conveyor belt system. This conveyor belt continuously transports grain from the inlet to the outlet, and during the discharge process, the grain is dispersed and distributed through the combined action of gravity and the inclination angle of the conveyor belt, ensuring that the grain forms a uniform accumulation layer in the grain silo, laying the foundation for subsequent storage management.

[0003] Currently, during the actual operation of grain loading machines, there are significant spatial differences in the accumulation of grain within the grain silo, with some areas exhibiting excessively dense or sparse accumulation. This uneven distribution significantly reduces the effective utilization rate of the grain silo's storage space, resulting in wasted storage capacity. Furthermore, it may cause problems such as poor ventilation and abnormal local temperature and humidity during grain accumulation, thereby affecting the long-term storage quality of the grain. Summary of the Invention

[0004] To address the problems of uneven grain distribution and inconvenience in grain loading machines mentioned in the background art, the present invention aims to provide an intelligent grain loading machine equipped with a grain silo leveling device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent silo loading machine equipped with a grain silo leveling device, comprising a base plate, a turntable mounted on the base plate, a first support mounted on the turntable, a second support hinged to the first support, a conveyor belt mounted on the second support, a discharge hopper mounted at one end of the second support, the discharge hopper and the discharge hopper both being configured to cooperate with the conveyor belt, and an ultrasonic sensor mounted on the lower side of the first support; A grain silo leveling device is installed at one end of the second bracket. The grain silo leveling device includes a box body, which is fixedly installed on the second bracket. A guide trough is rotatably installed on the lower side of the box body. A gear ring is fixedly installed on the outer side of the guide trough. A first servo motor is fixedly installed on the box body. The first servo motor drives a gear connected to it. The gear meshes with the gear ring. A third bracket is fixedly installed on the box body. The shaft of the first servo motor passes through the third bracket.

[0006] Preferably, a number of casters are mounted on the underside of the base plate, a number of support feet are mounted on the base plate, and a drive motor is fixedly mounted on the base plate, the drive motor driving the first bracket.

[0007] Preferably, a counterweight is fixedly installed on the first support, a hydraulic support rod is installed between the first support and the second support, and a feed hopper is installed on the second support.

[0008] Preferably, a plurality of stop bars are installed inside the box, a separation box is fixedly installed on the box, a filter plate is rotatably installed inside the separation box, a first limiting plate and a second limiting plate are fixedly installed inside the separation box, the filter plate is correspondingly arranged with the first limiting plate and the second limiting plate, and an electric push rod is installed inside the separation box, the upper end of the electric push rod is hinged to the filter plate, and the lower end of the electric push rod is hinged to the separation box.

[0009] Preferably, an impurity guide groove is fixedly installed on one side of the second bracket, the impurity guide groove is inclined, and the upper end of the impurity guide groove is connected to the inside of the separation box.

[0010] Preferably, a suction groove is embedded and fixed on the housing, the suction groove is connected to the separation box through a first connecting pipe, and a baffle is fixedly installed inside the housing, the baffle being correspondingly arranged with the suction groove.

[0011] Preferably, a Roots blower is also provided on one side of the housing. The air inlet of the Roots blower is connected to the separation box through a second connecting pipe. A blowing plate is fixedly installed in the material guide trough. The air outlet of the Roots blower is connected to the blowing plate through a third connecting pipe. The blowing plate is hollow inside and has several blowing holes. A three-way solenoid valve is installed on the third connecting pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In practical application, this invention uses a Roots blower to create a negative pressure environment inside the housing. The negative pressure airflow adsorbs impurities in the housing and introduces them into the separation chamber. The filter plate installed in the separation chamber achieves efficient separation of impurities and gas through physical interception. The separated impurities are trapped on the upper side of the filter plate. The electric push rod precisely controls the tilt angle of the filter plate, causing the impurities accumulated on the filter plate to be discharged in a directional manner along the impurity guide groove. After separation, the clean gas is pressurized by a Roots blower and then transported to the inside of the blowing plate through the third connecting pipe. The blowing holes evenly distributed on the surface of the blowing plate discharge airflow at a specific angle. The direction of this airflow and the trajectory of the falling grain form a synergistic effect, which significantly improves the throwing distance of the grain through pneumatic assistance. The three-way solenoid valve can precisely adjust the airflow intensity of the blowing holes, thereby realizing intelligent control of the grain falling distance. The first servo motor can be used to adjust the spreading direction of the conveyor belt, the hydraulic support rod can be used to adjust the tilt angle of the conveyor belt, and the third bracket can be used to position the orientation of the guide trough. These mechanical adjustment mechanisms, together with the data on the flatness of the grain surface and the status of the material level at each point collected in real time by the ultrasonic sensor, form a closed-loop control. Through multi-parameter coordinated adjustment, the uniform distribution of grain in the grain silo can be achieved, which significantly improves the accuracy and efficiency of the loading operation.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1 , Figure 2 and Figure 4As shown in the figure, the intelligent silo loading machine equipped with a grain silo leveling device provided in this embodiment mainly includes a base plate 101. Several nylon casters 102 are symmetrically arranged on the underside of the base plate 101, which have good wear resistance and shock absorption performance to ensure that the equipment remains stable during movement. Several hydraulic support feet 103 are evenly installed on the base plate 101. The base plate 101 is driven by hydraulic means, and the rapid lifting and fixing of the base plate 101 is achieved by controlling the extension and retraction of the hydraulic cylinder to prevent displacement of the machine during operation.

[0030] A turntable 104 is installed at the center of the upper surface of the base plate 101; a first bracket 106 is rotatably connected to the turntable 104 via a bearing seat; a drive motor 105 is fixedly installed on the lower side of the base plate 101; the motor is connected to the first bracket 106 via a reducer; the rotation angle of the first bracket 106 can be controlled by the motor, thereby realizing the adjustment of the loading direction.

[0031] The first support 106 is hinged to the upper end of the second support 108 via a hinge structure. A retractable conveyor belt 112 is mounted on the second support 108. The conveyor belt 112 is made of wear-resistant rubber and has anti-slip textures on its surface. A counterweight 107 is also fixedly mounted on the first support 106 to balance the weight of the conveyor belt 112 and the second support 108, ensuring the stability of the equipment operation. A hydraulic support rod 109 is provided between the first support 106 and the second support 108. This support rod adopts a two-way hydraulic cylinder structure. By controlling the inflow and outflow of hydraulic oil, the length of the support rod can be precisely adjusted, thereby changing the angle between the conveyor belt 112 and the horizontal plane to adapt to different loading height requirements.

[0032] In this embodiment, the conveyor belt 112 adopts a telescopic design, and the second support 108 adopts a telescopic structure accordingly. The two are linked to extend and retract through a synchronization mechanism. The telescopic conveyor belt 112 adopts a mature single-motor double-roller transmission system. The motor drives the active roller to rotate, which drives the driven roller to rotate synchronously, so as to realize the smooth operation of the conveyor belt 112. By controlling the extension length of the conveyor belt 112, the loading position can be precisely adjusted to meet the loading requirements of grain silos of different specifications.

[0033] The second support 108 has a discharge hopper 113 at its front end and a feed hopper 110 fixedly installed in the middle of the second support 108. The feed hopper 110 can be quickly connected to the grain discharge end of the grain conveyor. During operation, the ultrasonic sensor 111 installed on the lower side of the first support 106 can monitor the distribution of grain in the grain silo in real time. The sensor uses a high-frequency ultrasonic transmitting and receiving device, which can accurately detect the flatness of the grain surface and the material level status at each point, providing accurate data support for the silo loading operation.

[0034] In another embodiment of this application, based on the above embodiments, referring to Figures 1-5 , Figures 8-14 As shown, unlike the above embodiment, the discharge hopper 113 is no longer installed at one end of the second support 108. Instead, a grain bin leveling device 200 is installed at one end of the second support 108. The grain bin leveling device 200 is mainly composed of a box body 201, a guide trough 202, a toothed ring 203, a first servo motor 204, and a third support 206. The box body 201 is made of high-strength engineering plastic and is fixedly installed at the end of the second support 108 by bolt connection. The engineering plastic is lightweight, which can reduce the supporting pressure of the hydraulic support rod 109. A guide trough 202 is provided at the lower end of the box body 201 and is rotatably connected to the box body 201. A toothed ring 203 is provided on the outer circumference of the guide trough 202. The toothed ring 203 is integrally formed with the guide trough 202 or connected by fasteners.

[0035] A first servo motor 204 is fixedly installed on the housing 201 and is connected to the gear 205 through the motor output shaft. The gear 205 meshes with the toothed ring 203 on the outside of the guide trough 202. By controlling the rotation of the gear 205, the toothed ring 203 is driven to rotate, thereby realizing the angle adjustment of the guide trough 202.

[0036] A third bracket 206 is also fixedly installed on the housing 201. Several bearing assemblies are embedded inside the third bracket 206. The output shaft of the first servo motor 204 passes through the bearing assembly. The bearing assembly provides reliable radial support and axial positioning for the shaft of the first servo motor 204, ensuring the stable operation of the transmission system.

[0037] With the above structural configuration, the first servo motor 204 drives the gear 205 to mesh with the gear ring 203, thereby achieving precise angle adjustment of the guide chute 202, and thus controlling the grain loading direction to achieve the purpose of uniform grain distribution in the grain warehouse.

[0038] In another embodiment of this application, based on the above embodiment, a plurality of baffles 207 are installed inside the box 201 for the grain to impact the baffles 207, thereby separating the grain from its surface impurities. A separation box 208 is fixedly installed on the box 201, and a filter plate 2081 is rotatably installed inside the separation box 208. A first limiting plate 2082 and a second limiting plate 2083 are fixedly installed inside the separation box 208. The filter plate 2081 is correspondingly arranged with the first limiting plate 2082 and the second limiting plate 2083. An electric push rod 2084 is installed inside the separation box 208. The upper end of the electric push rod 2084 is hinged to the filter plate 2081, and the lower end of the electric push rod 2084 is hinged to the separation box 208. By controlling the extension and retraction of the electric push rod 2084, the precise angle adjustment of the filter plate 2081 can be achieved.

[0039] An impurity guide groove 212 is fixedly installed on one side of the second bracket 108. The impurity guide groove 212 is inclined and its upper end is connected to the inside of the separation box 208. A suction groove 215 is embedded and fixed on the box body 201. The suction groove 215 is connected to the separation box 208 through a first connecting pipe 209. The first connecting pipe 209 extends into the inside of the separation box 208. The part of the first connecting pipe 209 inside the separation box 208 has an opening for gas to enter the separation box 208. A baffle 2011 is fixedly installed inside the box body 201. The baffle 2011 is correspondingly set with the suction groove 215.

[0040] A Roots blower 210 is also installed on one side of the housing 201. The Roots blower 210 is fixed on the second bracket 108. The air inlet of the Roots blower 210 is connected to the separation box 208 through the second connecting pipe 211. A blowing plate 214 is fixedly installed inside the guide chute 202. The air outlet of the Roots blower 210 is connected to the blowing plate 214 through the third connecting pipe 213. The blowing plate 214 is hollow inside and has several blowing holes 2141. A three-way solenoid valve 216 is installed on the pipe 213. One end of the three-way solenoid valve 216 is connected to the air outlet of the Roots blower 210, the other end is connected to the third connecting pipe 213, and the other end is directly connected to the outside. The air flow rate into the third connecting pipe 213 can be controlled by the three-way solenoid valve 216. The blowing direction of the blowing hole 2141 is the same as the falling direction of the grain through the guide chute 202, so that when the blowing hole 2141 blows air, the falling speed of the grain can be increased.

[0041] In this embodiment, referring to the figure, the first connecting pipe 209 is located above the filter plate 2081, the impurity guide groove 212 and the second connecting pipe 211 are located below the filter plate 2081, and the first limiting plate 2082 and the second limiting plate 2083 are used to limit the rotation angle of the filter plate 2081.

[0042] It should be noted that, in the application of this invention, grain is fed onto the conveyor belt 112 through the feed hopper 110. After being conveyed by the conveyor belt 112, it strikes the stop bar 207 under the action of gravity (see reference). Figure 12 a1, which is the direction in which the grain is discharged through the conveyor belt 112, separates the grain from the impurities on its surface. The impurities are then sucked into the suction trough 215 by the action of the Roots blower 210 (see reference). Figure 12 (a5), impurities are discharged into the separation box 208 via the first connecting pipe 209. Gas passes through the filter plate 2081 and enters the blowing plate 214 via the second connecting pipe 211, the Roots blower 210, and the third connecting pipe 213, and is finally ejected through the blowing holes 2141 on the blowing plate 214. Impurities remain on the filter plate 2081. At this time, the filter plate 2081 is rotated by the electric push rod 2084 (refer to a5). Figure 6 and Figure 7 This causes impurities above the filter plate 2081 to fall into the impurity guide groove 212 and be discharged; while the grain falls into the feed guide groove 202 (see reference). Figure 12 (a2), after adjusting the orientation of the guide chute 202, the grain falls through the guide chute 202 (refer to a2). Figure 12 a3, which is the direction of grain falling), while the gas discharged from the Roots blower 210 is discharged through the blowing hole 2141 (refer to...). Figure 12 The gas discharged from the Roots blower 210 (a4) can blow the grain, causing it to fall further away, thereby adjusting the grain's landing point and improving the grain's storage operation. In this configuration, the gas discharged from the Roots blower 210 is recovered, greatly improving resource utilization. The orientation of the conveyor belt 112 can be controlled by the gear 205, the angle of the conveyor belt 112 can be controlled by the hydraulic support rod 109, the orientation of the guide chute 202 can be controlled by the third bracket 206, and the air force blown out of the blowing hole 2141 can be controlled by the three-way solenoid valve 216, thereby adjusting the distance the grain is sprayed. The above adjustments are based on the flatness of the grain surface and the material level status at each point detected by the ultrasonic sensor 111.

[0043] In another embodiment of this application, based on the above embodiment, another grain distribution method is adopted. The height of the grain surface is determined by the ultrasonic sensor 111, and the distance between the grain distribution end and the grain surface directly below it is always kept constant at 90±10cm (it should be noted that in this embodiment, the height of the grain surface directly below the grain distribution end is the average height of the grain surface in a 50 square centimeter area directly below the grain distribution end). Then, the grain is distributed at a uniform speed. The above grain distribution method can reduce dust, grain damage and impurity separation, and improve the safety of grain storage (the safety issue is mainly reflected in the fact that due to the differences in physical characteristics such as particle size, density, shape and surface state of grain grains and impurities, similar components (such as full grain grains, broken grain grains, light impurities, etc.) tend to gather in specific areas of the grain pile, thereby causing the redistribution of the components of the grain pile, which is extremely unfavorable for safe grain storage. In areas with more impurities, the grain moisture content is higher, the porosity is smaller, and insects and molds are more likely to grow, making it easy to heat up and mold. When mechanical ventilation or fumigation is used for pest control, the ventilation uniformity is poor and the agent penetration is difficult, affecting the ventilation and fumigation pest control effects).

[0044] It should be further noted that the above three embodiments further include an intelligent control system linked to the equipment. The system uses a programmable logic controller (PLC) as the core control unit, and the controller is fixedly installed on the base plate 101. This PLC control system precisely regulates and selects the operating parameters of each execution component in the production process through preset programs, including but not limited to: timing control of equipment start-up and shutdown, gradient adjustment of motor speed, and dynamic matching of material conveying rate. It should be noted that the PLC control system and its supporting industrial control protocol and signal acquisition module all adopt mature technical solutions in the field of mechanical automation. Its specific circuit topology and programming method are common knowledge to those skilled in the art, so this specification will not elaborate on its basic implementation details.
