Description

Technical Field

[0001] The utility model belongs to the field of manure treatment equipment, and in particular relates to a uniform material spreading device for a manure air dryer. Background Art

[0002] During the livestock breeding process, a spreading device is used to spread the manure to facilitate drying of the manure.

[0003] For example, Chinese patent CN217866283U discloses a rotary material leveling device for manure treatment, which includes a conveyor belt and a base. The lower end of the conveyor belt on the feeding side is rotatably mounted on the base through a slewing support. A rotating guide rail is fixed on the base, and the bottom of the conveyor belt is slidably supported on the rotating guide rail. A telescopic part for driving the conveyor belt to rotate left and right is installed on the base near the slewing support side.

[0004] However, this device cannot detect whether there is material on the conveyor belt. When there is no material on the conveyor belt, the conveyor belt still swings left and right, causing uneven material laying.

[0005] Therefore, we propose a uniform spreading device for manure air drying machine to solve the above problems. Utility Model Content

[0006] With respect to this device, it is not possible to detect whether there is material on the conveyor belt. When there is no material on the conveyor belt, the conveyor belt still swings left and right, causing the problem of uneven material spreading. The utility model provides a uniform material spreading device for a manure air dryer.

[0007] The utility model solves the technical problem by adopting the following solution: a uniform material spreading device for a manure air dryer, comprising a support base, a bracket, a belt conveyor, a drive unit and a material detection unit, wherein the bracket is rotatably mounted on the top of the support base;

[0008] One end of the belt conveyor is installed on the top of the bracket, and the drive unit is installed on the support base and connected to the bracket to drive the bracket and the belt conveyor to swing back and forth;

[0009] The material detection unit includes a rotating shaft, a touch plate, two limit switches and two parallel mounting plates. The two mounting plates are located at the other end of the belt conveyor and are respectively installed on the front and rear sides of the belt conveyor.

[0010] The rotating shaft is rotatably mounted between two mounting plates, and an eccentric wheel is mounted on one end of the rotating shaft;

[0011] The touch panel is mounted on the shaft and located between the two mounting plates;

[0012] The second limit switch is adapted to be arranged below the eccentric wheel and is mounted on a corresponding mounting plate.

[0013] Preferably, two limit switches 1 are installed on the support base, and the two limit switches 1 are symmetrically arranged on the front and rear sides of the support base.

[0014] Preferably, the driving unit includes two symmetrically arranged hydraulic cylinders, both ends of the hydraulic cylinders are hinged to the fixing seat and the connecting seat respectively through pins, the fixing seat is installed on the supporting seat, and the connecting seat is installed on the bracket.

[0015] Preferably, it further comprises a hydraulic pump station, which is connected to the two hydraulic cylinders respectively through two groups of hydraulic pipelines.

[0016] Preferably, the bracket is rotatably mounted on the top of the support seat via a slewing bearing.

[0017] Preferably, a U-shaped baffle is provided at the feed end of the belt conveyor.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The utility model transports materials through a belt conveyor. When the material passes through the touch plate, the touch plate will drive the rotating shaft and the eccentric wheel to rotate a certain angle. The eccentric wheel rotates and presses the limit switch 2 to close, proving that there is material on the belt conveyor. At this time, the two hydraulic cylinders are allowed to operate, driving the belt conveyor to swing back and forth to ensure the uniformity of material spreading.

[0020] 2. When there is no material on the belt conveyor, the touch plate resets, and at the same time drives the rotating shaft and the eccentric wheel to rotate and reset. At this time, the eccentric wheel no longer presses the limit switch 2, and the two sets of hydraulic cylinders stop running, and the belt conveyor no longer swings.

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See also Figure 1-3 The utility model provides a technical solution for a uniform spreading device of a manure and sewage air dryer:

[0027] Example 1:

[0028] according to Figure 1-3 As shown, it includes a support base 1, a bracket 5, a belt conveyor 2, a drive unit and a material detection unit. The bracket 5 is rotatably installed on the top of the support base 1 through a slewing bearing 6, so that the bracket 5 can rotate stably.

[0029] One end of the belt conveyor 2 is mounted on the top of the bracket 5, and a U-shaped baffle is provided at its feed end to prevent material from spilling.

[0030] The driving unit includes two symmetrically arranged hydraulic cylinders 32. The two ends of the hydraulic cylinders 32 are hinged to the fixed seat 31 and the connecting seat 33 through pins. The fixed seat 31 is installed on the support seat 1, and the connecting seat 33 is installed on the bracket 5. The two hydraulic cylinders 32 cooperate with each other in telescopic action to drive the bracket 5 and the belt conveyor 2 to swing back and forth. The hydraulic cylinders 32 can provide stable power output for the reciprocating swinging action of the belt conveyor 2, thereby ensuring the stability of the reciprocating swing of the belt conveyor 2.

[0031] Two limit switches 4 are installed on the support base 1. The two limit switches 4 are symmetrically arranged on the front and rear sides of the bracket 5 to control the position of the belt conveyor 2 swinging back and forth.

[0032] The material detection unit includes a rotating shaft 75, a touch plate 72, a limit switch 2 74 and two parallel mounting plates 71. The two mounting plates 71 are located at the other end of the belt conveyor 2 and are respectively installed on the front and rear sides of the belt conveyor 2.

[0033] Both ends of the rotating shaft 75 are respectively fitted with bearings, and the two bearings are respectively mounted on the two mounting plates 71 so that the rotating shaft 75 can rotate stably. One end of the rotating shaft 75 is fitted with an eccentric wheel 73.

[0034] The touch plate 72 is mounted on the rotating shaft 75 and is located between the two mounting plates 71. The limit switch 2 74 is adapted to be arranged below the eccentric wheel 73 and is mounted on the corresponding mounting plate 71. When the material passes through the touch plate 72, the touch plate 72 will drive the rotating shaft 75 and the eccentric wheel 73 to rotate a certain angle. The eccentric wheel 73 rotates and presses the limit switch 2 74 to close, proving that there is material on the belt conveyor 2. At this time, the two hydraulic cylinders 32 are allowed to operate, driving the belt conveyor 2 to swing back and forth to ensure the uniformity of material spreading.

[0035] When there is no material on the belt conveyor 2, the touch plate 72 is reset, and at the same time, the rotating shaft 75 and the eccentric wheel 73 are driven to rotate and reset. At this time, the eccentric wheel 73 no longer presses the limit switch 2 74, and the two groups of hydraulic cylinders 32 stop running, and the belt conveyor 2 no longer swings.

[0036] Example 2:

[0037] Based on the first embodiment, Figure 1 As shown, the hydraulic pump station 34 is further included. The hydraulic pump station 34 is connected to the two hydraulic cylinders 32 through two groups of hydraulic pipelines 35 respectively.
