Description

Technical Field

[0001] The invention relates to the technical field of dung drying, in particular to a drum type cow dung drying machine. Background Art

[0002] Livestock and poultry manure dryer is an important agricultural equipment. It can dry livestock and poultry manure quickly and effectively to make it an organic fertilizer. It not only helps to solve the problem of livestock and poultry manure pollution, but also brings economic benefits to farmers or enterprises. At present, the traditional drum dryer is mostly used for drying livestock and poultry manure, which includes a rotatable drying cylinder, an air inlet and a discharge port are arranged at one end of the drying cylinder, an air outlet and a feed port are arranged at the other end of the drying cylinder, and continuous spiral blades are arranged on the inner wall of the drying cylinder. When it is in use, hot air is passed into the drying cylinder from the air inlet and then discharged from the air outlet. The material to be dried enters the drying cylinder from the feed port. As the drying cylinder rotates, the material turns over in the drying cylinder and is transported along the axial direction of the drying cylinder to the discharge port under the action of the spiral blades, thereby achieving the drying of the material.

[0003] Since the traditional drum dryer uses continuous spiral blades to convey materials, the spiral blades are shielded near the inner wall of the drying drum, and the hot air mainly flows through the center of the drying drum, which results in a small contact area between the material and the hot air during drying and low drying efficiency. Compared with other livestock and poultry manure, cow dung has a fine texture and higher water content. Using traditional drum dryers often requires multiple dryings, which takes a long time and increases energy consumption. Summary of the invention

[0004] The object of the present invention is to overcome the deficiencies of the prior art and to provide a drum-type cow dung dryer which has high drying efficiency and can effectively reduce the drying time and energy consumption when used for drying cow dung.

[0005] The objective of the present invention is achieved through the following technical solutions: A drum-type cow dung dryer comprises a drying component, the drying component comprises a support frame and a drying cylinder, the drying cylinder is rotatably connected to the support frame, one end of the drying cylinder is provided with an air inlet and a material outlet, the other end of the drying cylinder is provided with an air outlet and a material feed port, the air inlet, the air outlet, the material feed port and the material outlet are all provided on the support frame and are connected to the interior of the drying cylinder, the inner wall of the drying cylinder is provided with a plurality of copying plates, the copying plates are arranged along the radial direction of the drying cylinder, and the plurality of copying plates are arranged on the drying cylinder. The spiral lines are evenly arranged on the inner wall of the cylinder. When in use, the drying cylinder is continuously rotated, and hot air is introduced into the drying cylinder from the air inlet and discharged from the air outlet. The material enters the drying cylinder from the feeding port, and the material is turned over by the rotation of the drying cylinder and the stirring of the lifting plate. At the same time, the material can be transported along the axial direction of the drying cylinder by the spirally arranged lifting plate until it is discharged from the discharge port, thereby achieving the drying of the material. In the drying process, since several lifting plates are arranged at intervals, the introduced hot air can also fill more areas in the drying cylinder, which is beneficial to improving the drying efficiency.

[0006] The invention also includes a support assembly, which includes a vibration plate, a support plate and a vibration mechanism. The vibration plate and the support plate are sequentially arranged below the drying cylinder. The support frame is fixedly mounted on the vibration plate. One end of the vibration plate close to the discharge port is rotatably connected to the support plate. The vibration mechanism includes a gear A, a gear B, a bevel gear A, a bevel gear B, a vibration shaft, a vibration crank and a vibration slider. The gear A, the gear B and the vibration shaft are all rotatably connected to the vibration plate. The gear A is meshed with the gear B. The bevel gear A is coaxially fixedly connected with the gear B. The bevel gear B is fixedly sleeved on the vibration shaft. The bevel gear B is meshed with the bevel gear A.

The vibration slider is slidably connected to the support plate. A transmission gear is fixedly sleeved on the drying cylinder, and the transmission gear is meshed with the gear A. During the drying process, as the drying cylinder continues to rotate, the vibration plate and the drying cylinder can be driven to swing back and forth, so that the material in the drying cylinder is bumped, which is conducive to the turning of the material and improves the drying efficiency.

[0007] Furthermore, the support assembly also includes a base, the support plate is tiltedly arranged on the base, and the end of the support plate close to the discharge port is lower than the end of the support plate close to the feed port, thereby making the drying cylinder tilted. Combined with the process of material shaking in the drying cylinder, it is beneficial to improve the ability of material to be transported along the axial direction of the drying cylinder when several copying plates are arranged at intervals.

[0008] Furthermore, the support assembly also includes a tilting mechanism, which includes a tilting motor, a screw rod, a crossbeam and a strut; the screw rod is rotatably connected to the base, the tilting motor is used to drive the screw rod to rotate, the crossbeam is slidingly connected to the base, and the crossbeam is threadedly connected to the screw rod; one end of the support plate close to the discharge port is rotatably connected to the base, one end of the strut is rotatably connected to the support plate, and the other end of the strut is rotatably connected to the crossbeam; the tilting angle of the support plate can be adjusted by the tilting motor to meet the drying needs of materials of different types and drying requirements.

[0009] Furthermore, the copying plate is detachably connected to the drying drum, and copying plates of different shapes and sizes can be replaced according to the material type and drying requirements.

[0010] Specifically, the drying assembly further includes a discharging mechanism, which includes a cylinder, an auger and a discharging motor. The cylinder is fixedly connected to the drying cylinder, one end of the cylinder extends into the drying cylinder through the discharging port, a discharging inlet is provided on the upper side of the end of the cylinder extending into the drying cylinder, and a discharging outlet is provided on the lower side of the other end of the cylinder. The auger is rotatably arranged in the cylinder, and the discharging motor is fixedly connected to the cylinder, and the discharging motor is used to drive the auger to rotate. The discharging motor can drive the auger to rotate, and then the material in the drying cylinder near the discharging port can be transported outward to the discharging outlet for discharge. Even if the drying cylinder is tilted or swung during drying, the material can be conveniently collected.

[0011] Specifically, the drying component also includes a feed pipe, which is a hose. One end of the feed pipe is connected to the feed port, and the other end of the feed pipe is connected to an external feeding device. Even if the drying cylinder is tilted or swings during drying, feeding can be convenient.

[0012] Specifically, the drying component also includes a drying motor, which is fixedly mounted on the vibration plate. A driving gear is fixedly sleeved on the output shaft of the drying motor, and a drying gear is fixedly sleeved on the drying cylinder. The driving gear is meshed with the drying gear. Starting the drying motor can drive the driving gear to rotate, and then drive the drying cylinder to rotate through the drying gear, so as to achieve continuous rotation of the drying cylinder during the drying process.

The drying component includes a rotatable drying drum, one end of the drying drum is provided with an air inlet and a discharge port, the other end of the drying drum is provided with an air outlet and a feed port, the inner wall of the drying drum is provided with a plurality of shovels, and the plurality of shovels are evenly arranged along a spiral line on the inner wall of the drying drum; the supporting component includes a vibration plate, a supporting plate and a vibration mechanism, the drying drum is connected to the vibration plate through a supporting frame, one end of the vibration plate near the discharge port is rotatably connected to the supporting plate, and the drying drum is transmission-connected to the supporting plate through the vibration mechanism. When in use, hot air enters the drying drum from the air inlet and is discharged from the air outlet, and the material enters the drying drum from the feed port and is discharged from the discharge port, and the drying process of the material is realized by convection between the hot air and the material.

[0014] During the drying process, the material in the drying drum can be turned over as the drying drum rotates continuously. At the same time, the vibration plate and the drying drum can be continuously swung under the transmission of the vibration mechanism, thereby causing the material in the drying drum to bump and improve the turning effect of the material. Several lifting plates arranged along the spiral line can, on the one hand, drive the material to move toward the discharge port of the drying drum when the drying drum rotates. On the other hand, each lifting plate rotates with the drying drum to have a stir-frying effect, thereby improving the turning effect of the material. At the same time, since the lifting plates are arranged at intervals, the hot air introduced is not blocked and can flow through the entire drying drum. In general, the drum-type cow dung dryer improves the turning effect of the material and the filling effect of the hot air at the same time, which is conducive to full contact between the material and the hot air and improves the drying efficiency.

[0015] The discharge port end of the drying drum is tilted downward, and combined with the design of the vibration mechanism, it is beneficial to improve the ability of material to be transported along the axial direction of the drying drum when each copying plate is set at intervals, so as to meet the continuous drying requirements; a tilting mechanism is also provided to adjust the tilt angle of the drying drum to meet the drying needs of materials of different types and drying requirements.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0018] like Figures 1 to 7 As shown, a drum-type cow dung drying machine includes a drying component and a supporting component.

[0019] like Figure 3 , Figure 4 As shown, the drying assembly includes a support frame 1 and a drying drum 2, the drying drum 2 is rotatably connected to the support frame 1, an air inlet 3 and a discharge port are arranged at one end of the drying drum 2, and an air outlet 4 and a feed port are arranged at the other end of the drying drum 2, the air inlet 3, the air outlet 4, the discharge port and the feed port are all opened on the support frame 1 and communicated with the inside of the drying drum 2, and the inner wall of the drying drum 2 is provided with a plurality of shovels 5, the shovels 5 are arranged along the radial direction of the drying drum 2, and the plurality of shovels 5 are evenly arranged along the spiral line on the inner wall of the drying drum 2. When the drying assembly is drying, hot air is introduced into the drying drum 2 from the air inlet 3 and then discharged through the air outlet 4, and the material is put into the drying drum 2 from the feed port, so that the drying drum 2 is continuously rotated, which can drive the material to turn over in the drying drum 2, and at the same time in this process, the shovels 5 improve the turning effect of the material in a similar manner to stir-frying, and on the other hand, the spirally arranged shovels 5 can transport the material along the axial direction of the drying drum 2 until it is discharged from the discharge port, and in this process, the material is fully contacted with the introduced hot air to achieve drying. Compared with the traditional drum dryer, the drying component eliminates the continuous spiral blades and arranges a plurality of lifting plates 5 at intervals. On the one hand, it can make the material flipping more uniform, and on the other hand, it is conducive to allowing the hot air to flow through the entire drying cylinder 2, which makes the material fully contact with the hot air and is conducive to improving the drying efficiency.

[0020] like Figure 2 , Figure 5 , Figure 7As shown, the support assembly includes a vibration plate 6, a support plate 7 and a vibration mechanism, wherein the vibration plate 6 and the support plate 7 are sequentially arranged below the drying drum 2, and the support frame 1 is fixedly mounted on the vibration plate 6, and one end of the vibration plate 6 near the discharge port is rotatably connected to the support plate 7. The vibration mechanism includes a gear A8, a gear B9, a bevel gear A10, a bevel gear B11, a vibration shaft 12, a vibration crank 13 and a vibration slider 14, wherein the gear A8, the gear B9 and the vibration shaft 12 are all rotatably connected to the vibration plate 6, the gear A8 is meshed with the gear B9, the bevel gear A10 is coaxially fixedly connected with the gear B9, the bevel gear B11 is fixedly sleeved on the vibration shaft 12, the bevel gear B11 is meshed with the bevel gear A10, one end of the vibration crank 13 is fixedly connected to the vibration shaft 12, the other end of the vibration crank 13 is rotatably connected to the vibration slider 14, and the vibration slider 14 is slidably connected to the support plate 7. A transmission gear 15 is fixedly sleeved on the drying drum 2, and the transmission gear 15 is meshed with the gear A8. When in use, the support plate 7 is fixedly installed. During the drying process of the aforementioned drying assembly, as the drying cylinder 2 continues to rotate, the transmission gear 15 rotates therewith, which can drive the gear A8, gear B9, bevel gear A10, bevel gear B11 and vibration shaft 12 to rotate in sequence; since one end of the vibration crank 13 is fixedly connected to the vibration shaft 12, and the other end of the vibration crank 13 is slidably supported on the support plate 7 through the vibration slider 14, when the vibration shaft 12 rotates, it can drive the vibration plate 6 to swing up and down around the rotation connection point between it and the support plate 7. Since the drying cylinder 2 and the vibration plate 6 are fixedly connected through the support frame 1, during the drying process, as the drying cylinder 2 continues to rotate, the drying cylinder 2 swings with the vibration plate 6. For the material in the drying cylinder 2, it is also subjected to an effect similar to bumps, which is helpful to reduce the adhesion of the material to the inner wall of the drying cylinder 2 to a certain extent, improve the turning effect of the material, and improve the drying efficiency.

[0021] Further, such as Figure 2 , Figure 5 As shown, the support assembly also includes a base 16, which is fixedly mounted on the ground. The aforementioned support plate 7 is tiltedly arranged on the base 16, and the end of the support plate 7 close to the discharge port is lower than the end of the support plate 7 close to the feed port. Since the continuous spiral blade structure is replaced by a plurality of shovel plates 5 arranged at intervals in the drying cylinder 2, although the drying efficiency can be effectively improved, if the drying cylinder 2 is placed horizontally, its ability to axially transport materials is slightly insufficient. By tilting the support plate 7, the discharge port end of the drying cylinder 2 can be tilted downward, which is conducive to the auxiliary transportation of the material in the direction of the discharge port under the action of its own weight; when the drying cylinder 2 is tilted, the aforementioned vibration mechanism causes the material in the drying cylinder 2 to bump, which is further conducive to improving the material transportation capacity in the direction of the discharge port during the drying process.

[0022] Further, such as Figure 5 , Figure 6The support assembly further includes a tilting mechanism, which includes a tilting motor 17, a screw rod 18, a crossbeam 19 and a support rod 20. The screw rod 18 is rotatably connected to the base 16, the crossbeam 19 is slidably connected to the base 16, the crossbeam 19 is threadedly connected to the screw rod 18, the output shaft of the tilting motor 17 is fixedly connected to one end of the screw rod 18, the end of the support plate 7 close to the discharge port is rotatably connected to the base 16, one end of the support rod 20 is rotatably connected to the support plate 7, and the other end of the support rod 20 is rotatably connected to the crossbeam 19. When the tilting motor 17 rotates, it can drive the screw rod 18 to rotate, thereby pushing the crossbeam 19 to slide back and forth, and then the tilting angle of the support plate 7 can be adjusted through the support rod 20 to meet the drying requirements of different materials; when the tilting motor 17 stops rotating, the position locking after the tilting angle adjustment can be achieved under the self-locking action of the screw nut mechanism composed of the screw rod 18 and the crossbeam 19.

[0023] Furthermore, the lifting plate 5 is detachably connected to the drying drum 2, and during implementation, the lifting plate 5 of different shapes and sizes can be replaced according to the drying requirements of different materials.

[0024] Further, such as Figure 1 , Figure 2 , Figure 4 As shown, the drying assembly also includes a discharging mechanism, which includes a cylinder 21, an auger 22 and a discharging motor 23. The cylinder 21 is fixedly connected to the drying cylinder 2, one end of the cylinder 21 extends into the drying cylinder 2 through the discharging port of the drying cylinder 2, a discharging inlet is provided on the upper side of one end of the cylinder 21 extending into the drying cylinder 2, and a discharging outlet is provided on the lower side of the other end of the cylinder 21, the auger 22 is rotatably arranged in the cylinder 21, the discharging motor 23 is fixedly connected to the cylinder 21, and the output shaft of the discharging motor 23 is fixedly connected to one end of the auger 22. Since the drying cylinder 2 of the drum-type cow dung dryer is in swing and tilt when in use, it is difficult to smoothly collect materials if the discharging mechanism of the traditional drum-type dryer is used. With this improved design, the discharging motor 23 is started during the drying process, so that the auger 22 rotates continuously, and the materials at the discharging port end of the drying cylinder 2 enter the cylinder 21 through the discharging inlet, and are discharged from the discharging outlet under the action of the auger 22, so that the dried materials can be smoothly collected.

[0025] Since the drying drum 2 of the drum-type cow dung dryer is in use and there is a swing or tilt, the position of the feed port of the drying drum 2 will change. Figure 4 As shown, the drying component also includes a feed pipe 24, which is a hose. One end of the feed pipe 24 is connected to the feed port, and the other end of the feed pipe 24 can be fixedly arranged, which is conducive to connecting with external feeding equipment.

[0026] Further, such as Figures 1 to 3As shown, the drying component also includes a drying motor 25, which is fixedly mounted on the vibration plate 6. A driving gear 26 is fixedly sleeved on the output shaft of the drying motor 25, and a drying gear 27 is fixedly sleeved on the drying cylinder 2. The driving gear 26 is meshed with the drying gear 27. Starting the drying motor 25 can drive the driving gear 26 to rotate, and then drive the drying cylinder 2 to rotate through the drying gear 27, so as to realize continuous rotation of the drying cylinder 2 during the drying process.

[0027] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
