Description

Technical Field

[0001] The utility model relates to the technical field of grain kernel moisture detection, in particular to a grain kernel detector. Background Technique

[0002] When storing grains, it is necessary to detect the moisture inside the grain kernels. The moisture content inside the grain kernels is judged by a moisture detector to determine whether it is suitable for storage. The moisture detector detects by using the way of generating different resistances. The detection principle of the moisture detector is as follows: The motor drives two rolling wheels to rotate. The grains are placed between the two rolling wheels. The grain kernels are crushed by the rolling wheels. The moisture inside the grain kernels is squeezed out. The circuit between the two rolling wheels is conducted under the action of moisture. Different moisture contents result in different resistance values. The moisture content inside the grain kernels is judged in this way.

[0003] There is a grain moisture detector with anti-blocking function with the publication number of CN209167278U. This patent uses a cleaning head to directly separate the grains from the rolling wheels. It is simple and convenient to use, improves the safety of workers' operation, and improves the accuracy of moisture detection. Since the cleaning head is an assembled structure, the damaged tooth openings 5 are very convenient to replace, and only local replacement is needed, which reduces the maintenance cost.

[0004] The inventor found in daily work that the above-mentioned grain moisture detector with anti-blocking function can only clean the grains on the outer circumferential surface of the second rolling wheel, and cannot clean the grains on the outer circumferential surface of the first rolling wheel, so there are certain limitations in use. Content of the Utility Model

[0005] The purpose of the utility model is to solve the technical problems in the above background, and to propose a grain kernel detector.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: A grain kernel detector, including a base, a detector body is fixedly installed on the surface of the base, two rolling wheels are rotatably connected to the surface of the detector body, two cleaning devices are arranged on the surface of the detector body, the cleaning device includes two support rods, the two support rods are fixedly installed on the surface of the detector body, an L-shaped bracket is fixedly installed at one end of the support rod away from the detector body, a chute is opened on the inner wall surface of the horizontal end of the L-shaped bracket, a sliding plate is slidably connected inside the chute, and a cleaning brush is fixedly installed at one end of the sliding plate away from the chute. The setting of the cleaning brush has the effect of cleaning the residual grain kernels on the surface of the rolling wheel.

[0007] Preferably, a through groove is formed on the inner wall surface of the vertical end of the L-shaped bracket. A sliding rod is fixedly installed between the inner wall surfaces at both ends of the through groove. Two moving plates are slidably connected to the surface of the sliding rod, and a spring is fixedly installed between the two moving plates. The spring serves to limit the position of the moving plate on the surface of the sliding rod.

[0008] Preferably, a hinged plate is hinged to the side surface of the moving plate, and one end of the hinged plate away from the moving plate is hinged to the cleaning brush. The hinged plate serves to drive the moving plate to move on the surface of the sliding rod.

[0009] Preferably, a collection device is provided on the side surface of the base. The collection device includes a transverse groove formed on the side surface of the base. A displacement plate is slidably connected inside the transverse groove, and a collection box is fixedly installed at one end of the displacement plate away from the transverse groove. The collection box serves to collect the cleaned grain kernels.

[0010] Preferably, a groove is formed on the surface of the base away from the transverse groove. An L-shaped plate is slidably connected inside the groove. Connecting rods are fixedly installed on both side surfaces of the vertical end of the L-shaped plate, and one end of the connecting rod away from the L-shaped plate is fixedly connected to the collection box. The L-shaped plate and the connecting rods serve to drive the collection box to move.

[0011] Preferably, a motor is fixedly installed on the surface of the vertical end of the L-shaped plate. An output end of the motor is fixedly installed with a gear, and a rack is fixedly installed on the surface of the base. The gear and the rack are meshed with each other. The motor serves to drive the gear to rotate, and the gear and the rack serve to move the L-shaped plate inside the groove.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, by providing a cleaning device, when the two rolling wheels roll the grain kernels and detect their internal moisture (note: the detection principle of the grain kernel moisture detector has been clearly described in the above background technology and is all existing mature technologies, so its principle will not be elaborated), when it is necessary to clean the grain kernels on the surfaces of the two rolling wheels, since the rotation of the two rolling wheels is controlled, the rotation of the rolling wheels will push the cleaning brush to move at this time. The movement of the cleaning brush drives the slide plate to move inside the chute. At the same time, the movement of the cleaning brush also drives the hinge plate to move. The movement of the hinge plate pushes the two moving plates to move away from each other on the surface of the sliding rod. The movement of the two moving plates away from each other on the surface of the sliding rod will drive the spring to stretch. At this time, the resilience of the spring is used to make the cleaning brush closely adhere to the outer sides of the circumferential sides of the two rolling wheels. Therefore, the cleaning brush can clean the remaining grain kernels on the circumferential sides of the two rolling wheels. Through the cooperation of the above structures, the device can clean the surfaces of the two rolling wheels simultaneously, thereby improving the practicality of the device during use.

[0014] 2. In the present utility model, by providing a collection device, when it is necessary to collect the grain kernels swept down, first start the motor. The start of the motor drives the gear to rotate. The rotation of the gear meshes with the rack, and then the L-shaped plate moves inside the groove. The movement of the L-shaped plate inside the groove drives the connecting rod to move. The movement of the connecting rod drives the collection box to move. The movement of the collection box drives the displacement plate to move inside the transverse groove. When the position where the collection box moves is located below the two rolling wheels, the motor can be turned off. Through the cooperation of the above structures, the collection box can collect the grain kernels swept down, improving the cleanliness of the surface of the base during the use of the device.

[0030] Specifically, a hinge plate 210 is hinged to the side surface of the moving plate 208, and one end of the hinge plate 210 away from the moving plate 208 is hinged to the cleaning brush 205. The hinge plate 210 is provided to drive the moving plate 208 to move on the surface of the sliding rod 207.

[0031] In this embodiment: A collecting device 3 is provided on the side surface of the base 1. The collecting device 3 includes a transverse groove 31 which is opened on the side surface of the base 1. A displacement plate 32 is slidably connected inside the transverse groove 31, and a collecting box 33 is fixedly installed at one end of the displacement plate 32 away from the transverse groove 31. When it is necessary to collect the cleaned grain kernels, first start the motor 37. The motor 37 starts to drive the gear 38 to rotate. The gear 38 rotates and meshes with the rack 39, so that the L-shaped plate 35 moves inside the groove 34. The movement of the L-shaped plate 35 inside the groove 34 drives the connecting rod 36 to move. The movement of the connecting rod 36 drives the collecting box 33 to move. The movement of the collecting box 33 drives the displacement plate 32 to move inside the transverse groove 31. When the position where the collecting box 33 moves is located below the two rolling wheels 5, just turn off the motor 37. Through the cooperation of the above structures, the collecting box 33 can collect the cleaned grain kernels, improving the cleanliness of the surface of the base 1 when the device is in use.

[0036] Working principle: By setting up the cleaning device 2, when the two rolling wheels 5 roll the grain kernels and detect their internal moisture content (Note: The detection principle of the grain kernel moisture detector has been clearly described in the above background technology, and they are all existing mature technologies, so their principles will not be elaborated), when it is necessary to clean the grain kernels on the surfaces of the two rolling wheels 5, since the rotation of the two rolling wheels 5 is controlled, at this time, the rotation of the rolling wheels 5 will push the cleaning brush 205 to move. The movement of the cleaning brush 205 drives the slide plate 204 to move inside the chute 203. At the same time, the movement of the cleaning brush 205 also drives the articulated plate 210 to move. The movement of the articulated plate 210 pushes the two moving plates 208 to move away from each other on the surface of the slide rod 207. The movement of the two moving plates 208 away from each other on the surface of the slide rod 207 will drive the spring 209 to stretch. At this time, the resilience of the spring 209 is used to make the cleaning brush 205 closely adhere to the outer sides of the circumferential sides of the two rolling wheels 5. Therefore, the cleaning brush 205 can clean the grain kernel residues on the circumferential sides of the two rolling wheels 5. Through the cooperation of the above structures, the device can clean the surfaces of the two rolling wheels 5 simultaneously, thereby improving the practicability of the device during use. When it is necessary to collect the cleaned grain kernels, first start the motor 37. The start of the motor 37 drives the gear 38 to rotate. The rotation of the gear 38 meshes with the rack 39, and then the L-shaped plate 35 moves inside the groove 34. The movement of the L-shaped plate 35 inside the groove 34 drives the connecting rod 36 to move. The movement of the connecting rod 36 drives the collection box 33 to move. The movement of the collection box 33 drives the displacement plate 32 to move inside the transverse groove 31. When the position where the collection box 33 moves is located below the two rolling wheels 5, just turn off the motor 37. Through the cooperation of the above structures, the collection box 33 can collect the cleaned grain kernels, improving the cleanliness of the surface of the base 1 during the use of the device.
