Description

Technical Field

[0001] The present invention relates to the technical field of mosquito killing, and particularly to an insect killing machine for tobacco stacks with a cleaning mechanism. Background Art

[0002] There are often flying insects around tobacco stacks. Therefore, insect attracting lamps are used to attract and kill flying insects during use; Existing insect killing lamps attract flying insects through insect attracting lamp strips, and kill the flying insects through an annular electric wire mesh cover sleeved around the insect attracting lamp strips; The mosquitoes killed adhere to the surface of the annular electric wire mesh cover, affecting the use effect of the annular electric wire mesh cover. Moreover, when cleaning it manually under the action of external force, the killed flying insects are likely to enter the annular electric wire mesh cover, affecting the cleanliness inside; In view of the above problems, we propose an insect killing machine for tobacco stacks with a cleaning mechanism. Summary of the Invention

[0003] In view of the problem that the surface of the annular electric wire mesh cover in the above-mentioned existing technology is prone to adhere to the killed mosquitoes and is inconvenient to clean, we propose an insect killing machine for tobacco stacks with a cleaning mechanism.

[0004] An insect killing machine for tobacco stacks with a cleaning mechanism provided by the present invention includes an upper lamp base, a lower lamp base, an annular electric wire mesh cover, and an insect attracting lamp strip. The annular electric wire mesh cover is connected between the upper lamp base and the lower lamp base, and the insect attracting lamp strip is connected to the lower end of the upper lamp base and is located inside the annular electric wire mesh cover; A one-way displacement type cleaning mechanism attached to the surface of the annular electric wire mesh cover and a wind speed multiplying type air duct mechanism extending from the inside of the lower lamp base to the inside of the annular electric wire mesh cover are connected to the lower lamp base. The wind speed multiplying type air duct mechanism is connected to the one-way displacement type cleaning mechanism through a pulley mechanism. Under the forward and reverse rotation drive of the one-way displacement type cleaning mechanism, the wind speed multiplying type air duct mechanism switches between blowing and suction.

[0005] A further improvement scheme of the present invention, the one-way displacement type cleaning mechanism includes a displacement driving mechanism, a one-way rotation conversion joint, a reciprocating screw, and a cleaning plate mechanism; There are two sets of the displacement driving mechanisms, both of which are connected to the lower lamp base. There are two sets of the reciprocating screws. One set of the reciprocating screws is connected to the displacement driving mechanism through a one-way rotation conversion joint, and the other set of the reciprocating screws is connected to another displacement driving mechanism. The cleaning plate mechanism is sleeved on the surface of the annular electric wire mesh cover and is threadedly connected to the reciprocating screw.

[0006] A further improvement scheme of the present invention, the displacement driving mechanism includes a driving motor and a rotating shaft. The driving motor is connected to the lower lamp base, and the rotating shaft is fixedly connected to the output end of the driving motor.

[0007] A further improvement of the present invention, the one-way rotation adapter includes an adapter column, a ratchet wheel, a ratchet pawl, and a spring. The adapter column is a column with a cavity inside. The end of one of the rotating shafts far from the driving motor extends into the cavity of the adapter column and is rotatably connected to the adapter column. The ratchet wheel is arranged in the cavity and is coaxially and fixedly sleeved on the corresponding rotating shaft. The ratchet pawl is engaged with the ratchet wheel and is connected to the adapter column through a rotating rod. The spring is arranged in the cavity, and the two ends are respectively connected to the ratchet pawl and the adapter column. The other set of reciprocating screws is fixedly connected to the end of the corresponding rotating shaft, and the upper ends of the two reciprocating screws are both connected to the upper lamp holder.

[0008] A further improvement of the present invention, the cleaning plate mechanism includes an annular support sleeve, a cleaning plate, and a threaded sleeve. The annular support sleeve is sleeved on the surface of the annular grid cover. An annular cavity is provided inside the annular support sleeve. The cleaning plate is of an annular structure and is arranged in the annular cavity. The cleaning plate is sleeved on the surface of the annular grid cover.

[0009] A further improvement of the present invention, the wind speed multiplier air duct mechanism includes a rotary air duct disc mechanism, a bevel gear type wind speed multiplier mechanism, and an axial flow wind mechanism. The rotary air duct disc mechanism includes a turntable, an L-shaped air duct, a horn-shaped nozzle, and a collecting pipe. The lower lamp holder is a columnar structure with an opening at the upper end and a cavity inside. The turntable is arranged in the opening and is rotatably connected to the lower lamp holder. The L-shaped air duct passes through the turntable from the cavity body and extends into the annular grid cover. The horn-shaped nozzle is arranged in the annular grid cover and is connected to the L-shaped air duct in an array manner. The collecting pipe is arranged in the cavity body and is fixedly connected to the lower end of the turntable.

[0010] A further improvement of the present invention, the bevel gear type wind speed multiplier mechanism includes a bevel gear one, a bevel gear two, a bevel gear three, and a fixed shaft rod. The bevel gear one is coaxially and fixedly sleeved on the collecting pipe. The bevel gear two is engaged with the bevel gear one and is rotatably connected to the lower lamp holder through the fixed shaft rod. The bevel gear three is engaged with the bevel gear two.

[0011] A further improvement of the present invention, the axial flow wind mechanism includes an air outlet pipe, a support frame, a fan shaft, and axial flow fan blades. The air outlet pipe is coaxially and fixedly passed through the bevel gear three. The air outlet pipe is hermetically and rotatably connected to the collecting pipe. The support frame is fixedly connected inside the air outlet pipe. The fan shaft is connected to the support frame. The axial flow fan blades are arranged in the collecting pipe and are connected to the fan shaft.

[0012] A further improvement of the present invention, the pulley mechanism includes pulleys and a connecting belt. There are two pulleys, which are respectively coaxially and fixedly sleeved on the surfaces of the rotating shaft and the collecting pipe. The two pulleys are connected by the connecting belt.

[0013] Advantages of the present invention: A tobacco stack insect exterminator with a cleaning mechanism provided by the present invention: First, the displacement driving mechanism is activated. The reciprocating screw rod is driven to rotate through the one-way rotation adapter, driving the cleaning plate mechanism to move up and down to clean the surface of the annular grid cover. Second, during cleaning, the displacement driving mechanism drives the rotating air duct disc mechanism to rotate through the pulley mechanism, and then drives the axial flow air mechanism to rotate through the bevel gear type wind speed doubling mechanism, blowing outward to prevent the dirt removed from entering the annular grid cover. Third, when the displacement driving mechanism starts to rotate in the reverse direction, the corresponding threaded rod is not driven to rotate through the one-way rotation adapter. The rotating air duct disc mechanism is driven to rotate through the pulley mechanism, and then the axial flow air mechanism is driven to rotate through the bevel gear type wind speed doubling mechanism. When cleaning, the rotation direction of the axial flow air mechanism is opposite. Therefore, at this time, it is in the air suction state, adsorbing the mosquitoes outside the annular grid cover to prevent the mosquitoes from escaping. Fourth, through the bevel gear type wind speed doubling mechanism, the wind speed of the axial flow fan can be doubled, increasing the adsorption and blowing effects. Description of the Drawings

[0028] According to Figures 1 - 10A tobacco stack insect exterminator with a cleaning mechanism is shown, which includes an upper lamp holder 1, a lower lamp holder 2, an annular electric wire mesh cover 3, and an insect attracting lamp strip. The annular electric wire mesh cover 3 is connected between the upper lamp holder 1 and the lower lamp holder 2, and the insect attracting lamp strip is connected to the lower end of the upper lamp holder 1 and is located inside the annular electric wire mesh cover 3. A one-way displacement type cleaning mechanism 4 that fits on the surface of the annular electric wire mesh cover 3 is connected to the lower lamp holder 2. The one-way displacement type cleaning mechanism 4 includes a displacement driving mechanism 7, a one-way rotation adapter 8, a reciprocating screw 9, and a cleaning plate mechanism 10. There are two sets of displacement driving mechanisms 7, both of which are connected to the lower lamp holder 2. There are two sets of reciprocating screws 9. One set of reciprocating screws 9 is connected to the displacement driving mechanism 7 through the one-way rotation adapter 8, and the other set of reciprocating screws 9 is connected to another displacement driving mechanism 7. The one-way rotation adapter 8 includes a joint column 13, a ratchet 14, a pawl 15, and a spring 16. The joint column 13 is a column with a cavity 17 inside. The end of one rotating shaft 12 away from the driving motor 11 extends into the cavity 17 of the joint column 13 and is rotatably connected to the joint column 13. The ratchet 14 is arranged in the cavity 17 and is coaxially and fixedly sleeved on the corresponding rotating shaft 12. The pawl 15 meshes with the ratchet 14 and is connected to the joint column 13 through a rotating rod 18. The spring 16 is arranged in the cavity 17 and its two ends are respectively connected to the pawl 15 and the joint column 13, so that the ratchet 14 meshes with the pawl 15. The other set of reciprocating screws 9 is fixedly connected to the end of the corresponding rotating shaft 12. The upper ends of the two reciprocating screws 9 are both connected to the upper lamp holder 1. By using the ratchet 14 and the pawl 15, the rotating shaft 12 can drive the corresponding reciprocating screw 9 to rotate when rotating in one direction, and will not drive the corresponding reciprocating screw 9 to rotate when rotating in the other direction. The cleaning plate mechanism 10 is sleeved on the surface of the annular electric wire mesh cover 3 and is threadedly connected to the reciprocating screw 9.

The cleaning plate mechanism 10 includes an annular support sleeve 19, a cleaning plate 20, and a threaded sleeve 21. The annular support sleeve 19 is sleeved on the surface of the annular electric wire mesh cover 3. An annular cavity is provided inside the annular support sleeve 19. The cleaning plate 20 is of an annular structure and is arranged in the annular cavity. The cleaning plate 20 is sleeved on the surface of the annular electric wire mesh cover 3. When the two driving motors 11 start to drive the cleaning plate mechanism 10 to move up and down, their output ends rotate simultaneously, in the same direction, and at the same speed.

[0029] A wind speed multiplier type air duct mechanism 5 extending from the inside of the lower lamp holder 2 to the inside of the annular grid cover 3 is connected to the lower lamp holder 2. The wind speed multiplier type air duct mechanism 5 is connected to the unidirectional displacement type cleaning mechanism 4 through a pulley mechanism 6. Driven by the forward and reverse rotation of the unidirectional displacement type cleaning mechanism 4, the wind speed multiplier type air duct mechanism 5 switches between blowing and suction. The wind speed multiplier type air duct mechanism 5 includes a rotary air duct disc mechanism 22, a bevel gear type wind speed multiplier mechanism 23, and an axial flow air mechanism 24. The rotary air duct disc mechanism 22 includes a turntable 25, an L-shaped air duct 26, a horn-shaped nozzle 27, and a collecting pipe 28. The lower lamp holder 2 is a columnar structure with an opening at the upper end and a cavity inside. The turntable 25 is arranged in the opening and is rotatably connected to the lower lamp holder 2. The L-shaped air duct 26 extends from the cavity through the turntable 25 to the inside of the annular grid cover 3. The horn-shaped nozzle 27 is arranged inside the annular grid cover 3 and is arrayedly connected to the L-shaped air duct 26. The collecting pipe 28 is arranged inside the cavity and is fixedly connected to the lower end of the turntable 25. The bevel gear type wind speed multiplier mechanism 23 includes a first bevel gear 29, a second bevel gear 30, a third bevel gear 31, and a fixed shaft rod 32. The first bevel gear 29 is coaxially and fixedly sleeved on the collecting pipe 28. The second bevel gear 30 meshes with the first bevel gear 29 and is rotatably connected to the lower lamp holder 2 through the fixed shaft rod 32. The third bevel gear 31 meshes with the second bevel gear 30. Through the rotation directions of the first bevel gear 29, the second bevel gear 30, and the third bevel gear 31, the relative rotation speed between the collecting pipe 28 and the air outlet pipe 33 is doubled, increasing the air volume of the axial flow air mechanism 24. The axial flow air mechanism 24 includes an air outlet pipe 33, a support frame 34, a fan shaft 35, and axial flow fan blades 36. The air outlet pipe 33 is coaxially and fixedly passed through the third bevel gear 31. The air outlet pipe 33 is hermetically and rotatably connected to the collecting pipe 28. The support frame 34 is fixedly connected inside the air outlet pipe 33. The fan shaft 35 is connected to the support frame 34. The axial flow fan blades 36 are arranged inside the collecting pipe 28 and are connected to the fan shaft 35.

[0030] In a further improved solution of the present invention, the pulley mechanism 6 includes a pulley 37 and a connecting belt 38. There are two pulleys 37, which are respectively coaxially and fixedly sleeved on the surfaces of the rotating shaft 12 and the collecting pipe 28. The two pulleys 37 are connected by the connecting belt 38. The pulley 37 and the connecting belt 38 are both provided with anti-slip patterns, which can prevent the pulley 37 and the connecting belt 38 from slipping.

[0031] The principle of the present invention: During cleaning, the two drive motors 11 are started to drive the corresponding rotating shafts 12 to rotate. One of the rotating shafts 12 drives the ratchet wheel 14 to rotate, drives the joint column 13 to rotate through the pawl 15, drives the corresponding reciprocating screw rod 9 to rotate, and the other rotating shaft 12 drives the corresponding reciprocating screw rod 9 to rotate, drives the threaded sleeve 21 to move up and down, drives the annular support sleeve 19 and the cleaning plate 20 to move up and down, and cleans the surface of the annular grid cover 3. During cleaning, the rotating shaft 12 on one of the drive motors 11 drives the manifold 28 to rotate through the pulley mechanism 6, drives the first bevel gear 29 to rotate, drives the second bevel gear 30 to rotate, drives the third bevel gear 31 to rotate in the opposite direction to the second bevel gear 30, drives the air outlet pipe 33, the support frame 34, the fan shaft 35, and the axial flow fan blades 36 to rotate. The axial flow fan blades 36 blow air, and through the manifold 28, the L-shaped air duct 26, and the bell mouth 27, the air blows towards the annular grid cover 3, blowing away the dirt cleaned by the cleaning plate mechanism 10. Moreover, when the manifold 28 rotates, the L-shaped air duct 26 and the bell mouth 27 rotate, increasing the blowing range. And the rotating direction of the manifold 28 is opposite to that of the air outlet pipe 33. Therefore, relative to the self-rotation of the axial flow fan blades 36, the wind speed is greater and the effect is better. When cleaning is not required, the drive motor 11 not connected to the one-way rotation conversion joint 8 does not start, and the other drive motor 11 starts. It does not drive the corresponding reciprocating screw 9 to rotate through the one-way rotation conversion joint 8, but only drives the manifold 28 to rotate through the pulley mechanism 6. At this time, the rotation direction of the manifold 28 is opposite to that during cleaning. It drives the first bevel gear 29 to rotate, drives the second bevel gear 30 to rotate, drives the third bevel gear 31 to rotate in the opposite direction to the second bevel gear 30, drives the air outlet pipe 33, the support frame 34, the fan shaft 35, and the axial flow fan blades 36 to rotate. The axial flow fan blades 36 suck air at this time, and suck air in the order of the bell mouth 27, the L-shaped air duct 26, the manifold 28, and the air outlet pipe 33, sucking in the flying insects that fly near the annular grid cover 3. Moreover, when the manifold 28 rotates, the L-shaped air duct 26 and the bell mouth 27 rotate, increasing the adsorption range. And the rotating direction of the manifold 28 is opposite to that of the air outlet pipe 33. Therefore, relative to the self-rotation of the axial flow fan blades 36, the air suction speed is greater and the effect is better.

Therefore, the protection scope of the present invention should be defined by the claims.
