Description

Technical Field

[0001] This utility model relates to a refrigeration machine, specifically a grain cooler motor bracket, and a grain cooler having the motor bracket. Background Technology

[0002] Grain coolers can handle the problem of overheated grain in emergencies and are an important guarantee for grain storage facilities to achieve the goals of green grain storage and scientific grain preservation. After cooling one grain silo, the grain cooler needs to be transported to the next grain silo for cooling, so the grain cooler needs to be transported frequently between grain silos.

[0003] For grain coolers, the motor driving the fan blades is fixedly installed inside the grain cooler via a motor bracket. The motor bracket primarily supports the motor and fan blades vertically. Grain coolers need to be frequently transported between grain silos, which are often located in remote areas with uneven road surfaces. During transport, grain coolers frequently experience severe jolting. The horizontal fixation of the motor bracket for the motor and fan blades is insufficient, and the bracket is prone to deformation under continuous jolting, affecting the function of the motor and fan blades. In severe cases, the stress concentration points of the motor bracket may even break, rendering the grain cooler unusable. Utility Model Content

[0004] This utility model first provides a motor bracket for a grain cooler, the purpose of which is to improve the fixing effect of the motor bracket on the motor and fan blades.

[0005] The technical solution adopted by this utility model is: a grain cooler motor bracket, including two mounting plates located on the same plane and a connecting rod connecting the two mounting plates into a whole. The two sides of the mounting plates are the front and the back, respectively. The two mounting plates are respectively provided with motor mounting holes. The mounting plates are arranged vertically, and the output shaft of the motor is located on the front of the mounting plate. The lower ends of the two mounting plates are respectively fixedly connected to a base plate, and the two base plates are located on the same horizontal plane. The upper ends of the two mounting plates are respectively fixedly connected to a constraint frame.

[0006] To facilitate the processing and fabrication of the mounting plate and the base plate, the lower end of the mounting plate is further formed by bending it 90° towards its front side to create the base plate.

[0007] During operation and transportation, the motor and mounting plate of the grain cooler will vibrate frequently, and the connection between the mounting plate and the base plate is prone to deformation. In order to improve the strength of the connection between the mounting plate and the base plate and improve tear resistance, at least one reinforcing plate is provided at the inside corner formed by the mounting plate and the base plate.

[0008] To further reduce the obstruction of airflow by the mounting plate, the mounting plate is also provided with at least one ventilation hole.

[0009] To further ensure the strength of the mounting plate at the ventilation hole, the ventilation hole is rectangular with two vertical sides. A strip is provided on the back of the mounting plate along the vertical side of the rectangular hole. The strip is integral with the mounting plate and perpendicular to each other.

[0010] The constraint frame fixes and restrains the upper part of the mounting plate. Specifically, the constraint frame is right-angled, with one side of the right angle arranged vertically and its lower end fixedly connected to the top of the mounting plate, and the other side of the right angle arranged horizontally and facing the front of the mounting plate.

[0011] To further improve the overall fixation effect of the two mounting plates and the connecting rod, the connecting rod is further fixedly connected to a support rod, which is perpendicular to the connecting rod and arranged in a horizontal direction.

[0012] To balance the forces on the constraint frame and the support rod, the following further measures are taken: the two ends of the connecting rod are respectively connected to the upper ends of the two mounting plates, the support rod is located in the middle of the connecting rod and faces the front of the mounting plate, and the length of the support rod is the same as the length of the side of the constraint frame facing the front of the mounting plate.

[0013] The beneficial effects of this utility model's grain cooler motor bracket are as follows: The lower ends of the two mounting plates are respectively fixedly connected to base plates, which, after being fixedly installed inside the grain cooler, secure the lower ends of the mounting plates. The upper ends of the two mounting plates are respectively fixedly connected to constraint frames, which, after being installed inside the grain cooler, secure the upper ends of the mounting plates. Both the upper and lower ends of the mounting plates can be securely fixed inside the grain cooler. The motor driving the fan blades is fixedly installed in the motor mounting holes of the mounting plates, with the fan blades located directly in front of the mounting plates. The motor can be securely fixed inside the grain cooler, improving the vibration resistance of the grain cooler.

[0014] This utility model also provides a grain cooler, the purpose of which is also to improve the fixing effect of the motor bracket on the motor and fan blades, and improve the vibration resistance of the grain cooler. The technical solution adopted by this utility model is as follows: the grain cooler includes a shell with an air outlet, a panel fixed at the air outlet, the panel with an air outlet grille, and the interior of the grain cooler is provided with any of the above-mentioned grain cooler motor brackets. Two base plates are respectively fixedly installed inside the grain cooler, two constraint frames are respectively fixedly installed inside the grain cooler, a motor is fixedly installed in the motor mounting hole of the mounting plate, and a fan blade is installed on the output shaft of the motor. The fan blade is located in front of the mounting plate and corresponds to the air outlet grille.

[0015] Furthermore, one end of the constraint frame facing the front of the mounting plate is fixedly connected to the panel, and one end of the support rod is fixedly connected to the other end of the support rod, which is also fixedly connected to the panel.

[0016] The beneficial effects of this grain cooler are: the lower ends of the two mounting plates on which the motor and fan blades are installed are fixed by the base plate, and the upper ends are fixed by the constraint frame. The motor and fan blades can be firmly fixed inside the grain cooler, which improves the vibration resistance of the grain cooler. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] The first subject of this utility model is a motor bracket for a grain cooler, which is installed inside the grain cooler to support and fix the motor and fan blades. See also Figures 1-4 The grain cooler motor bracket includes two mounting plates 1 located on the same plane and a connecting rod 2 connecting the two mounting plates 1 into a whole. Both mounting plates 1 are used to directly mount the motor 8; therefore, each mounting plate 1 has a motor mounting hole 1-1, which is a circular hole, and a connecting piece for fixing the motor 8 is provided around the motor mounting hole 1-1. For example, the motor 8 is generally mounted to the motor mounting hole 1-1 by screws or bolts, and through holes for mounting screws or bolts are provided around the motor mounting hole 1-1. The motor 8 requires a connecting cable; to facilitate wiring, the mounting plate 1 also has a cable tray or a cable mounting bracket. The mounting bracket can be set on either side of the mounting plate 1, but is generally set on the back of the mounting plate 1.

[0024] Mounting plate 1 has two sides, a front and a back. Mounting plate 1 is vertically oriented, with the output shaft of motor 8 located on the front of mounting plate 1. This means the plane corresponding to mounting plate 2 is vertical, and motor 8, with fan blades 9 mounted on its output shaft, is installed in motor mounting hole 1-1. The output shaft of motor 8 and fan blades 9 are located directly in front of mounting plate 1. Base plates 3 are fixedly connected to the lower ends of both mounting plates 1. Base plates 3 are perpendicular to mounting plates 1 and directly support mounting plates 1. In use, base plates 3 are directly fixed inside the grain cooler. Base plates 3 are typically fixed with screws or bolts, therefore, they have through holes for screws and bolts. Base plates 3 and mounting plates 1 can be two separate parts connected to each other, or they can be a single unit. For example, to facilitate the manufacturing of mounting plates 1 and base plates 3, the lower end of mounting plate 1 is bent 90° towards its front end to form base plate 3. The lower ends of the two mounting plates 1 are generally at the same installation height, therefore the two base plates 3 are on the same horizontal plane. The connection between mounting plate 1 and base plate 3 is a stress concentration area, prone to deformation. To improve the strength and tear resistance of this connection, at least one reinforcing plate 5 is provided at the internal corner formed by the mounting plate 1 and base plate 3. The planes corresponding to any two of the mounting plate 1, base plate 3, and reinforcing plate 5 are perpendicular to each other. For example, see... Figure 4 Three parallel reinforcing plates 5 are installed between the mounting plate 1 and the base plate 3.

[0025] To improve the bending resistance of mounting plate 1, the two vertical sides of mounting plate 1 are provided with a flange structure, that is, the two vertical sides of mounting plate 1 are each bent at 90° towards their back side, such as... Figure 2 As shown. To reduce the weight of the mounting plate 1 and to minimize its obstruction of airflow, the mounting plate 1 is also provided with at least one ventilation hole 1-2. The ventilation holes 1-2 are generally located in the area corresponding to the fan blade 9. For example, in... Figures 1-4 In the illustrated embodiment, each mounting plate 1 is provided with two rectangular ventilation holes 1-2. To ensure the strength of the mounting plate 1 at the ventilation holes 1-2, when the ventilation holes 1-2 are rectangular holes, the rectangular holes have two vertical sides. A strip is provided on the back of the mounting plate 1 along the vertical sides of the rectangular holes. The strip is integral with the mounting plate 1 and perpendicular to each other, such as... Figure 2 As shown.

[0026] The connecting rod 2 is used to connect the two mounting plates 1 into a whole. The connecting rod 2 can be made of metal or non-metal. To ensure the strength of the connecting rod 2, it is generally made of metal, such as angle steel. To facilitate the connection between the mounting plate 1 and the connecting rod 2, the mounting plate 1 and the connecting rod 2 are generally connected by bolts. The connecting rod 2 can be connected to any position on the mounting plate 1. Since the lower ends of the two mounting plates 1 can generally be firmly fixed by the base plate 3, the connecting rod 2 is preferably connected to the top of the mounting plate 1, and the connecting rod 2 covers the entire top of the mounting plate 1, such as... Figures 1-4 As shown.

[0027] To secure the upper ends of the mounting plates 1, constraint frames 4 are fixedly connected to the upper ends of both mounting plates 1. The constraint frames 4 secure and constrain the upper ends of the mounting plates 1. The constraint frames 4 can be fixed in the grain cooler through methods such as bonding, abutment, snap-fit, welding, bolt connection, and screw connection. For example, see... Figures 1-4 The constraint frame 4 is right-angled, with one side of the right angle arranged vertically and its lower end fixedly connected to the top of the mounting plate 1, for example, by bolts simultaneously fixing it to the mounting plate 1 and the connecting rod 2. The other side of the right angle is arranged horizontally and faces the front of the mounting plate 1. The horizontal arrangement of one side of the constraint frame 4 and its facing the front of the mounting plate 1 allows the constraint frame 4 to be fixedly connected to the panel 7 at the air outlet of the grain cooler.

[0028] There is a certain distance between the two mounting plates 1 and the two constraint frames 4. To further improve the overall fixing effect of the two mounting plates 1 and the connecting rod 2, the connecting rod 2 can also be fixedly connected to the support rod 6. The support rod 6 is perpendicular to the connecting rod 2 and is arranged horizontally. In use, the support rod 6 is fixed inside the grain cooler by means of bonding, abutting, snapping, welding, bolting, screwing, etc. For example, the end of the support rod 6 is fixedly connected to the panel 7 at the air outlet of the grain cooler by screws or bolts. The motor bracket of the grain cooler is symmetrically arranged along the vertical centerline. In order to balance the force on the constraint frame 4 and the support rod 6, the two ends of the connecting rod 2 are respectively connected to the upper ends of the two mounting plates 1, and the support rod 6 is located in the middle of the connecting rod 2 and faces the front of the mounting plate 1. The length of the support rod 6 is preferably the same as the length of the side of the constraint frame 4 facing the front of the mounting plate 1, so that both the support rod 6 and the constraint frame 4 can be fixedly connected to the panel 7 at the air outlet of the grain cooler.

[0029] The second subject of this utility model is a grain cooler. For example... Figure 1As shown, the grain cooler includes a housing with an air outlet, a panel 7 fixed to the air outlet, and an air outlet grille on the panel 7. The grain cooler's interior contains the grain cooler motor bracket described in the first section. Two base plates 3 are fixedly installed inside the grain cooler, for example, by screws or bolts. Two constraint brackets 4 are also fixedly installed inside the grain cooler, for example, by bolts to the panel 7 at the air outlet. A motor 8 is fixedly installed in the motor mounting hole 1-1 of the mounting plate 1, for example, by bolts. The output shaft of the motor 8 is fitted with fan blades 9, which are located directly in front of the mounting plate 1 and correspond to the air outlet grille. The grain cooler is placed on a horizontal plane, with the mounting plate 1 aligned with the panel 7.

[0030] The mounting plate 1 of the grain cooler motor bracket is fixed by two base plates 3, two constraint frames 4 and support rods 6, so that the motor 8 and fan blades 9 fixedly installed on the mounting plate 1 can be firmly fixed inside the grain cooler, thereby improving the vibration resistance of the grain cooler.
