Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry equipment, in particular to a counterweight traction type wind deflector. Background Art

[0002] In order to ensure a better ventilation effect in the poultry house and prevent the outside wind from blowing directly onto the poultry in the poultry house, causing them to catch a cold and become sick, when opening the windows for ventilation in the poultry house, it is necessary to install an inclined wind guide plate at the window of the poultry house ventilation window, forming an upward inclined vent at the window, so that the outside wind first enters the upper center of the poultry house and then spreads to the surroundings, so that the ventilation speed of the poultry house is faster and the ventilation effect is better; the wind guide plate currently used is installed on the inner side of the poultry house, such as Figure 1 As shown, the outside wind passes through the mosquito-proof humidifying net 7 and enters the ventilation window. Under the action of the wind guide plate 1, it is blown upward at an angle into the poultry house to ventilate the poultry house. The advantage of the wind guide plate of this structure is that it can automatically open by its own weight and then close by the rack and motor. However, because it is set on the inner side of the poultry house, it occupies more space inside the poultry house and wastes space. Utility Model Content

[0003] The purpose of the utility model is to provide a counterweight traction type air deflector, which is installed outside the poultry house without changing the original ventilation direction and ventilation effect, and can save space in the poultry house; it is provided with a traction rope locking mechanism and a lubrication mechanism, and the two are linked by a connecting rod, so that the lubrication effect of the traction rope is better and the operation is simpler.

[0004] The utility model includes an air guide plate installed outside the ventilation window of a poultry house, the upper part of the air guide plate is rotatably installed above the ventilation window, and the lower part of the air guide plate is inclined toward the outside of the window, so that an upwardly inclined ventilation opening is formed between the lower part of the air guide plate and the ventilation window; the air guide plate is connected to a traction rope, and a counterweight block is fixed to the end of the traction rope, and the counterweight block can move downward to pull open the air guide plate.

[0005] Preferably, a pulley is fixedly installed on the upper part of the poultry house, one end of the traction rope is connected to the wind deflector, and the other end of the traction rope is passed around the wheel groove of the pulley and then connected to a counterweight block below the pulley.

[0006] Preferably, the side of the traction rope, located above the counterweight, is provided with a traction rope locking mechanism, which includes oppositely arranged locking blocks, and the side of the locking block is provided with a rope clamp for clamping the traction rope; the locking block is connected to a pressure plate, and the pressure plate presses the locking block under the pressure of the cam; the side of the cam is movably connected to a connecting rod, and the end of the connecting rod is movably connected to a rotating rod.

[0007] Preferably, a traction rope lubrication mechanism is provided above the locking mechanism, and the lubrication mechanism includes a shell, in which lubricating cotton is provided, and the lubricating cotton is provided with through holes running through the upper and lower ends of the lubricating cotton, and the traction rope passes through the through holes to achieve lubrication; a lubrication cavity is provided on the outside of the lubricating cotton, and lubricating oil is stored in the lubrication cavity, and an oil unloading hole is provided on the inner wall where the lubricating cavity contacts the lubricating cotton; a sliding rod is connected to the lubrication cavity, and the head of the sliding rod is provided with a plug for sealing the oil unloading hole, and the tail of the sliding rod extends out of the lubrication cavity and is movably connected to the rotating rod.

[0008] Preferably, a sliding sleeve is sleeved on the sliding rod, and the sliding sleeve is fixed to the outside of the housing.

[0009] In summary, the present invention has the following beneficial effects:

[0010] 1. The air deflector is set on the outside of the poultry house, which does not affect the original ventilation direction and ventilation effect, and can save space in the poultry house. The air deflector is connected to the traction rope and the counterweight block, and can also be opened automatically by the deadweight of the counterweight block, without the need for additional configuration of other structures, thus saving costs;

[0011] 2. A traction rope locking mechanism is provided to lock and fix the traction rope, preventing the counterweight from shaking and causing the wind deflector to shake when the wind blows, and also preventing the counterweight from rotating and shaking and causing the traction rope to become tangled;

[0012] 3. It is equipped with a lubrication mechanism, which lubricates the traction rope in real time when the traction rope moves, which has a better lubrication effect on the traction rope. There is no need to lubricate and maintain the traction rope separately and regularly, which saves labor and prevents the traction rope from being exposed to the air for a long time and rusting due to lack of sufficient lubrication, affecting its use effect and service life. At the same time, the installation position of the lubrication mechanism is low, which is convenient for adding lubricating oil to the lubrication cavity, and the operation is simple and convenient.

[0013] 4. The lubrication mechanism and the locking mechanism are linked together through a connecting rod. By operating one handle, the locking mechanism and the lubrication mechanism can be opened and closed at the same time. One operation realizes two functions, which is simpler and more convenient to operate, reduces the operating steps of the operator, and ensures that as long as the traction rope is moving, it is in a lubricated state. When the traction rope stops moving, the lubrication also stops. This avoids the occurrence of uneven lubrication of the traction rope, prevents oil leakage and waste of lubricating oil, and avoids insufficient lubrication of the traction rope due to forgetfulness or improper operation by the operator.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] The orientations mentioned in this specification are based on the orientations of the counterweight-traction-type wind deflector of the present invention during normal operation, and do not limit the orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0023] like Figures 2 to 6 As shown together, a counterweight traction type wind guide plate includes a wind guide plate 1 installed outside the ventilation window of the poultry house. The upper part of the wind guide plate 1 is provided with a rotating shaft, and the rotating shaft is fixed to the upper part of the ventilation window of the poultry house. The upper part of the wind guide plate 1 is rotatably installed above the ventilation window, and the lower part of the wind guide plate 1 is inclined toward the outside of the window, thereby forming an upward inclined vent between the lower part of the wind guide plate 1 and the ventilation window.

[0024] A pulley 4 is fixedly installed on the upper part of the poultry house, one end of the traction rope 2 is connected to the wind guide plate 1, and the other end of the traction rope 2 passes around the wheel groove of the pulley 4, and is connected to a counterweight 3 below the pulley 4. The counterweight 3 can move downward to pull open the wind guide plate 1 to achieve window ventilation; preferably, the traction rope 2 is connected to the lower part of the wind guide plate 1, so that when the traction rope 2 pulls the wind guide plate 1, the lever arm is longer and more labor-saving; preferably, the counterweight 3 is a cylindrical structure, and the counterweight 3 is filled with high-density materials, such as sand, iron blocks, cement mixtures, etc., so that the overall size of the counterweight 3 is smaller and the appearance is more beautiful and generous.

[0025] When it is necessary to open the window for ventilation, the counterweight 3 moves downward under the action of gravity, and the lower part of the wind guide plate 1 is driven to rotate upward by the traction rope 2 to open the ventilation window. At this time, the wind outside the poultry house is blown upward through the vent to the upper center of the poultry house, and then diffuses to the surrounding areas of the poultry house to refresh the air inside the poultry house. This structure does not change the original air inlet direction of the ventilation window, nor does it affect the ventilation effect of the poultry house, and can also achieve the opening of the wind guide plate 1. The wind guide plate 1 is set on the outside of the poultry house to save space inside the poultry house.

[0026] A closing device is provided on the inner side of the air guide plate 1, and the closing device includes a drive motor, which is connected to a drive shaft, a drive gear is fixed to the drive shaft, and an arc-shaped rack is engaged on the drive gear. The end of the arc-shaped rack is fixed to the bottom of the air guide plate 1. When the drive motor is started, the drive gear is driven to rotate, thereby realizing the closing of the air guide plate 1. This part is the existing technology and is not the main innovation of this patent. It will not be introduced in detail here.

[0027] Furthermore, a traction rope 2 locking mechanism 5 is provided on the side of the traction rope 2, which is located above the counterweight 3. The locking mechanism 5 includes opposite locking blocks 501, with a gap between the two locking blocks 501, and a rope clamp 502 for clamping the traction rope 2 on the side of the locking block 501; the locking block 501 is connected to the pressure plate 503, and a pad 507 is installed in the pressure plate 503. A cam 504 is provided on the side of the pad 507. The locking block 501, the pressure plate 503, the pad 507 and the cam 504 are connected in series through a connecting screw 510. A core shaft 508 is connected in the cam 504. The core shaft 508 connects one end of the connecting screw 510 to the cam The wheels 504 are connected in series, and the other end of the connecting screw 510 is also provided with an adjusting nut 511 for adjustment; the cam 504 is connected to the handle 509, and the handle 509 is turned to make the cam 504 rotate around its core shaft 508, and the pressure plate 503 presses the locking block 501 under the pressure of the cam 504, driving the rope clamp 502 to tighten, thereby achieving the locking and fixation of the traction rope 2 to prevent the counterweight block 3 from shaking and driving the wind guide plate 1 to shake when it is windy, and it can also prevent the counterweight block 3 from rotating and shaking to cause the traction rope 2 to be knotted; it should be noted that the locking mechanism of the cam 504 is a prior art and is not the main innovation of this patent, and will not be introduced in detail here.

[0028] A traction rope 2 lubrication mechanism 6 is provided above the locking mechanism 5. The lubrication mechanism 6 includes a shell 601. A lubricating cotton 602 is provided in the shell 601. The lubricating cotton 602 is provided with a through hole running through the upper and lower ends of the lubricating cotton 602. The traction rope 2 passes through the through hole to achieve lubrication; a lubricating cavity 603 is provided on the outside of the lubricating cotton 602. Lubricating oil is stored in the lubricating cavity 603. An oil unloading hole 604 is provided on the inner wall of the lubricating cavity 603 in contact with the lubricating cotton 602. The lubricating oil enters the lubricating cotton 602 through the oil unloading hole 604 to replenish the lubricating oil in the lubricating cotton 602; the lubricating cavity 603 is provided with an oil filling hole, and lubricating oil can be replenished to the lubricating cavity 603 through the oil filling hole.

[0029] A lubrication mechanism 6 is provided above the counterweight 3 to lubricate the traction rope 2 in real time without additional operation, which has a better lubrication effect on the traction rope 2 and prevents the traction rope 2 from being exposed to the air for a long time and rusting due to lack of sufficient lubrication, thereby affecting its use effect and service life. At the same time, the installation position of the lubrication mechanism 6 is relatively low, which makes it convenient to add lubricating oil to the lubrication cavity 603, and the operation is simple and convenient.

[0030] The side of the cam 504 of the locking mechanism 5 is movably connected with a connecting rod 505, and the end of the connecting rod 505 is movably connected with a rotating rod 506; a sliding rod 605 is connected to the lubrication chamber 603, and the head of the sliding rod 605 is provided with a plug 606 for sealing the oil unloading hole 604, and the tail of the sliding rod 605 extends out of the lubrication chamber 603 and is movably connected to the rotating rod 506; the handle 509 of the cam 504 of the locking mechanism 5 is opened, and when the handle 509 moves downward, the locking mechanism 5 is opened, and the traction rope 2 is not locked and can move up and down. At this time, the lower end point of the connecting rod 505 movably connected to the side of the cam 504 moves downward around the core shaft 508 of the cam 504, driving the rotating rod 506 to move downward. When the handle 509 moves upward, the locking mechanism 5 is closed, and the traction rope 2 is locked and cannot move. At this time, the lowermost point of the connecting rod 505 movably connected to the side of the cam 504 moves upward around the core shaft 508 of the cam 504, driving the rotating rod 506 to move upward, and the sliding rod 605 moves inward, and the plug 606 blocks the oil unloading hole 604, and the lubricating oil in the lubrication chamber 603 cannot enter the lubricating cotton 602, so as to prevent the lubricating oil in the lubrication chamber 603 from continuously flowing out when the traction rope 2 is stationary, causing waste and pollution.

[0031] The lubricating mechanism 6 and the locking mechanism 5 are linked together through the connecting rod 505. By operating a handle 509, the locking mechanism 5 and the lubricating mechanism 6 can be opened and closed at the same time. One operation realizes two functions, which is simpler and more convenient to operate, reduces the operating steps of the operator, ensures that the traction rope 2 is in a lubricated state as long as it is moving, and avoids insufficient lubrication of the traction rope 2 due to forgetfulness or improper operation.

[0032] Furthermore, a sliding sleeve 607 is sleeved on the sliding rod 605 , and the sliding sleeve 607 is fixed to the outside of the housing 601 ; the sliding sleeve 607 guides the sliding rod 605 to ensure its horizontal movement.
