Description

Technical Field

[0001] The invention provides a drag reduction and consumption reduction device, which relates to the technical field of vibration drag reduction, and in particular to a vibration drag reduction and consumption reduction device for a rotary tiller. Background Art

[0002] The rotary tiller is the core structure of the rotary tiller. It cuts, breaks and lifts the soil through rotation, making the soil softer, more breathable and finer, which is conducive to the growth of crops. However, the energy consumption of the rotary tiller is 3-6 times that of general tilling equipment. There is also a method of reducing soil friction by vibrating the rotary tiller.

[0003] Although the existing method of vibrating the rotary tiller can make the rotary tiller have a certain vibration effect, on the one hand, the vibration itself consumes energy, and on the other hand, most of the vibrations generated by this method are disordered and ineffective. It is necessary to choose to generate effective vibrations perpendicular to the direction of the rotation axis in order to truly reduce resistance and energy consumption, or improve the rotary tillage effect.

[0004] To this end, technicians in this field have proposed a vibration drag reduction and consumption reduction device for a rotary tiller. By improving the structure of the existing rotary tiller and adding effective vibration components, the vibration drag reduction and consumption reduction of the rotary tiller can be achieved and the rotary tillage effect can be guaranteed. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a vibration drag reduction and consumption reduction device for a rotary tiller, which changes the working mode of the prior art in which all blades are driven to vibrate irregularly through a unified vibration generating structure, and the blades are driven by an installing shaft to till the soil. An inner drive shaft which rotates independently and can adjust its position is arranged on the inner side of the installing shaft to perform targeted vibration on the blades on the tilling side. This vibration mode not only avoids the driving loss of the blades in the non-tilling state, but also controls the vibration in the direction along the rotation radius of the installing shaft, thereby avoiding a large amount of disordered and invalid vibration loss.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a vibration drag reduction and consumption reduction device for a rotary tiller, comprising a mounting shaft and a blade plugged into the side of the mounting shaft, the blade being mounted on the side of the mounting shaft, and the side blade being driven to rotate by the mounting shaft to till the land.

[0007] Since the energy consumption of tilling machines is much greater than that of similar equipment, in order to reduce energy consumption or pursue better tilling effects, there is also a method in the prior art that uses ultrasonic equipment or eccentric wheel structures to drive the blades to vibrate. However, on the one hand, the prior art uses an overall drive method to synchronously drive all the blades and even the mounting shafts to vibrate, and the blades that are not in contact with the soil are ineffective energy consumption. On the other hand, the vibration generated by this method is irregular, and only a small part of the vibration has an effect on reducing the drag and energy consumption of the blades.

[0008] Therefore, technicians in this field insert an inner drive shaft on the inner side of the installation shaft, and the installation shaft and the inner drive shaft are independently installed and driven respectively. A vibration bump is fixed on the side of the inner drive shaft, and the blade is pushed to the outside by the vibration bump.

[0009] In addition, a return spring is tightly arranged on the side of the blade, and the return spring applies an elastic force in the opposite direction of the vibration bump to the blade to help reset it, thereby achieving vibration resistance reduction of the blade along the radial direction of the installation axis.

[0010] On the one hand, the installation shaft and the inner drive shaft driven separately facilitate the adjustment of the vibration frequency of the blade, and on the other hand, facilitate the effective vibration drive of the blade in the working direction to avoid a large amount of additional losses.

[0011] Preferably, a mounting sleeve is fixedly connected to the side of the mounting shaft, the blade is inserted into the inner side of the mounting sleeve, and multiple groups of mounting sleeves are evenly arranged on the side of the mounting shaft. The blades are installed on the side of the mounting shaft with a suitable density according to usage requirements to form a complete rotary tiller.

[0012] The side of the blade corresponds to the mounting sleeve sliding sleeve with an end cover, the blade is inserted into the mounting sleeve through the end cover, the return spring is fixed on the side of the end cover, and the blade is pressed against the inner bottom of the mounting sleeve through the return spring.

[0013] This clamping structure is different from the half-elastic component in the prior art. The elastic force of the return spring is used to press the blade to the inner bottom of the mounting sleeve. The force applied to the blade when it contacts the soil during rotary tillage is consistent with the direction of the elastic force of the return spring. Only when the blade is pushed into place by the vibrating bump and loses the clamping force can the blade be stably installed in the mounting sleeve, thereby preventing the blade from loosening and increasing the damage rate of the equipment.

[0014] Preferably, a positioning bolt is provided through the side of the mounting sleeve, and an entry slide groove is provided on the side of the blade corresponding to the positioning bolt, and the positioning bolt is slidably connected to the blade via the entry slide groove.

[0015] Preferably, a fixing block is fixed to the end of the blade, a sleeve is fixed to one side of the end cover and the fixing block close to each other, and the return spring is tightly arranged between the end cover and the fixing block through the sleeve.

[0016] The positioning bolt is plug-in-connected with the mounting sleeve and the end cover, so that the end cover is fixedly installed in the mounting sleeve, while the positioning bolt and the blade are slidably installed, ensuring that the vibration protrusion can drive the blade to vibrate in an advancing manner.

[0017] Furthermore, the end cover and the blade are in a sliding engagement relationship, which ensures that the blade can be slidably installed within a certain range in the installation sleeve, but will not be disengaged under the elastic force of the return spring.

[0018] Preferably, a lever is fixedly connected to the side of the blade, a hole is penetrated through the side of the mounting shaft corresponding to the lever, the lever extends into the mounting shaft through the hole and is slidably connected thereto, and the vibration protrusion drives the driving blade via the lever.

[0019] When the inner drive shaft rotates, the vibration lug periodically contacts and pushes the lever, and the lever is subjected to the thrust to compress the reset spring to cause the blade to advance. As the vibration lug continues to move, the elastic force of the reset spring pushes the blade to quickly reset, thereby achieving vibration of the blade within a small range.

[0020] Preferably, a slide rail is fixed to the outer side of the end of the mounting shaft, and a bearing seat is slidably engaged with the inner side of the slide rail. The inner drive shaft is slidably arranged on the inner side of the mounting shaft through the bearing seat. The diameter of the inner drive shaft is smaller than the radius of the mounting shaft, thereby ensuring the advance adjustment of the inner drive shaft on the inner side of the mounting shaft. The advance adjustment of the inner drive shaft controls the advance drive distance of the vibration protrusion to the lever, thereby realizing the adjustment of the amplitude of the device.

[0021] Preferably, a reinforcing rod is fixedly connected to the side of the bearing seat parallel to the inner drive shaft, and a support block is fixedly connected to the side of the reinforcing rod. The inner drive shaft passes through the support block and is connected to the bearing thereof. The reinforcing rod supports the middle section of the inner drive shaft through a plurality of support blocks to prevent the vibration protrusion from bending and being damaged due to the reverse force of the blade, thereby enhancing the strength of the vibration drive structure.

[0022] Preferably, a guide bar is fixedly connected to the side surface of the inner drive shaft, and a sleeve is slidably connected to the side surface of the inner drive shaft through the guide bar. The vibration protrusion is evenly fixed on the side surface of the sleeve in a ring shape, and the sleeve slidably arranged on the side surface of the inner drive shaft can be adjusted to the installation position accordingly, thereby changing the density of the vibration protrusion facing the blade position, thereby realizing the adjustment of different vibration frequencies of the blade at the same rotation speed of the inner drive shaft.

[0023] Because the installation of the side reinforcement rod and the support block of the inner drive shaft causes the problem that the side sleeve of the inner drive shaft cannot be installed continuously, technical personnel in this field insert and install an advance rod on the inner side of the inner drive shaft, and insert and install a positioning pin on the side of the advance rod. The positioning pin passes through the sleeve and is slidably connected to the inner drive shaft.

[0024] When the density of the vibration bumps needs to be adjusted, the advancement rod is pushed, and the advancement rod synchronously drives multiple discontinuous sliding sleeves to slide equidistantly along the inner drive shaft through the positioning pin, thereby achieving synchronous adjustment of the density setting of multiple groups of vibration bumps.

[0025] The present invention discloses a vibration resistance reduction and consumption reduction device for a rotary tiller, which has the following beneficial effects:

[0026] 1. The vibration drag reduction and consumption reduction device of the rotary tiller adopts an inner drive shaft with independent power drive arranged on the inner side of the installation shaft to perform directional vibration drive on the blade. On the one hand, it avoids the power loss problem caused by driving all the blades to vibrate at the same time. On the other hand, it specifically drives the blades to vibrate along the radial direction of the installation shaft to avoid power loss caused by disordered vibration. When the installation shaft and the inner drive shaft rotate at different frequencies, the vibration protrusion periodically pushes the blades to advance along the radial direction of the installation shaft, and cooperates with the reset spring to realize small-range vibration. The small-range vibration of the blade in contact with the soil is beneficial to drag reduction and consumption reduction.

[0027] 2. The vibration drag reduction and consumption reduction device of the rotary tiller is a device in which the blade is slidably installed on the side of the mounting shaft through the cooperation of the end cover and the mounting sleeve, and a spring is arranged to press the blade against the bottom of the mounting sleeve. When the blade is vibrated and driven by the inner driving shaft, the effect is not affected by the attenuation of the elastic coefficient of the reset spring, and the elastic force of the reset spring ensures that the blade is stably installed on the side of the mounting shaft, avoiding the problem of loose installation and easy damage of the blade.

[0028] 3. The vibration drag reduction and consumption reduction device of the rotary tiller is characterized in that the inner drive shaft is slidably arranged on the inner side of the mounting shaft through a slide rail, and the amplitude of the blade vibration can be adjusted by adjusting the mounting position of the inner drive shaft. As the position of the inner drive shaft changes, the distance between the vibration protrusion installed on the side of the inner drive shaft and the inner wall of the mounting shaft also changes, and then the driving distance of the vibration protrusion to the lever also changes accordingly.

[0029] 4. The vibration drag reduction and consumption reduction device of the rotary tiller is provided with a reinforcing rod on one side of the inner drive shaft to ensure the stable vibration driving effect of the inner drive shaft on the blade. The reinforcing rod supports the middle section of the inner drive shaft through multiple groups of support blocks to ensure the strength of the inner drive shaft. In addition, the vibration protrusion is slidably arranged on the side of the inner drive shaft through a sliding sleeve, and the side of the sliding sleeve is provided with vibration protrusions of different density ranges. By adjusting the sliding sleeve range facing the blade, the vibration frequency can also be adjusted on the basis of a certain rotation speed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The embodiment of the present invention discloses a vibration resistance and consumption reduction device for a rotary tiller;

[0040] According to the attached Figure 1 and attached Figure 2 As shown, it includes a mounting shaft 1 and a blade 2 plugged into the side of the mounting shaft 1. The blade 2 is mounted on the side of the mounting shaft 1. The mounting shaft 1 drives the side blade 2 to rotate to till the land.

[0041] Because the energy consumption of tilling machines is much greater than that of similar equipment, in order to reduce energy consumption or pursue better tilling effects, the prior art also uses ultrasonic equipment or an eccentric wheel structure to drive the blade 2 to vibrate. However, on the one hand, the prior art uses an overall drive method to synchronously drive all blades 2 and even the mounting shaft 1 to vibrate, and the blades 2 that are not in contact with the soil are invalid energy consumption. On the other hand, the vibration generated by this method is irregular, and only a small part of the vibration has an effect on reducing the drag and energy consumption of the blade 2.

[0042] Therefore, technicians in this field insert an inner drive shaft 3 on the inner side of the installation shaft 1, and the installation shaft 1 and the inner drive shaft 3 are independently installed and driven respectively. A vibration bump 4 is fixed on the side of the inner drive shaft 3, and the vibration bump 4 is used to push the blade 2 to move outward.

[0043] In addition, a return spring 5 is tightly arranged on the side of the blade 2, and the return spring 5 applies an elastic force in the opposite direction of the vibration bump 4 to the blade 2 to help reset, thereby achieving vibration resistance reduction of the blade 2 along the radial direction of the installation shaft 1.

[0044] On the one hand, the separately driven mounting shaft 1 and the inner drive shaft 3 facilitate the adjustment of the vibration frequency of the blade 2, and on the other hand, facilitate the effective vibration drive of the blade 2 in the working direction to avoid a large amount of additional loss.

[0045] According to the attached Figure 2 and attached Figure 3 As shown, a mounting sleeve 6 is fixedly connected to the side of the mounting shaft 1, and the blade 2 is inserted and arranged inside the mounting sleeve 6. Multiple groups of mounting sleeves 6 are evenly arranged on the side of the mounting shaft 1. According to the needs of use, the blade 2 is installed on the side of the mounting shaft 1 with a suitable density to form a complete rotary tiller.

[0046] The side of the blade 2 corresponds to the mounting sleeve 6 and is slidably sleeved with an end cover 7. The blade 2 is inserted into the mounting sleeve 6 through the end cover 7. The return spring 5 is fixed to the side of the end cover 7, and the blade 2 is pressed against the inner bottom of the mounting sleeve 6 through the return spring 5.

[0047] This clamping structure is different from the half-elastic component in the prior art. The elastic force of the reset spring 5 is used to press the blade 2 to the inner bottom of the mounting sleeve 6. The force applied to the blade 2 when it contacts the soil during rotary tillage is consistent with the direction of the elastic force of the reset spring 5. Only when the blade 2 is pushed into place by the vibrating bump 4 and loses the clamping force can the blade 2 be stably installed in the mounting sleeve 6, thereby preventing the blade 2 from loosening and increasing the damage rate of the equipment.

[0048] A positioning bolt 8 is provided through the side of the mounting sleeve 6 , and an entry slide groove 9 is provided on the side of the blade 2 corresponding to the positioning bolt 8 , and the positioning bolt 8 is slidably connected to the blade 2 through the entry slide groove 9 .

[0049] A fixing block 10 is also fixed to the end of the blade 2 , a sleeve 11 is fixed to one side of the end cover 7 and the fixing block 10 close to each other, and the return spring 5 is tightly arranged between the end cover 7 and the fixing block 10 through the sleeve 11 .

[0050] The positioning bolt 8 is plug-in-connected with the mounting sleeve 6 and the end cover 7, so that the end cover 7 is fixedly installed in the mounting sleeve 6, while the positioning bolt 8 is slidably installed with the blade 2, ensuring that the vibration protrusion 4 can drive the blade 2 to vibrate in an advancing manner.

[0051] Furthermore, the end cover 7 and the blade 2 are in a sliding engagement relationship, which ensures that the blade 2 can be slidably installed within a certain range in the installation sleeve 6, but will not be disengaged under the elastic force of the reset spring 5.

[0052] According to the attached Figure 4 As shown, a lever 12 is fixedly connected to the side of the blade 2, and a hole 13 is penetrated through the side of the mounting shaft 1 corresponding to the lever 12. The lever 12 extends into the mounting shaft 1 through the hole 13 and is slidably connected thereto. The vibration protrusion 4 drives the blade 2 through the lever 12.

[0053] When the inner drive shaft 3 rotates, the vibrating protrusion 4 periodically contacts and pushes the lever 12. The lever 12 is subjected to the thrust and compresses the reset spring 5 to make the blade 2 move forward. As the vibrating protrusion 4 continues to move, the elastic force of the reset spring 5 pushes the blade 2 to quickly reset, thereby achieving vibration of the blade 2 within a small range.

[0054] A slide rail 14 is fixed to the outer side of the end of the mounting shaft 1, and a bearing seat 15 is slidably engaged with the inner side of the slide rail 14. The inner drive shaft 3 is slidably set on the inner side of the mounting shaft 1 through the bearing seat 15. The diameter of the inner drive shaft 3 is smaller than the radius of the mounting shaft 1, thereby ensuring the advance adjustment of the inner drive shaft 3 on the inner side of the mounting shaft 1. The advance adjustment of the inner drive shaft 3 controls the advance driving distance of the vibration protrusion 4 to the lever 12, thereby realizing the adjustment of the amplitude of the device.

[0055] According to the attached Figure 5 As shown, a reinforcing rod 16 is fixedly connected to the side of the bearing seat 15 parallel to the inner drive shaft 3, and a support block 17 is fixedly connected to the side of the reinforcing rod 16. The inner drive shaft 3 passes through the support block 17 and is connected to the bearing therewith. The reinforcing rod 16 supports the middle section of the inner drive shaft 3 through a plurality of support blocks 17 to prevent the vibration protrusion 4 from bending and being damaged due to the reverse force of the blade 2, thereby enhancing the strength of the vibration drive structure.

[0056] A guide bar 18 is fixedly connected to the side of the inner drive shaft 3, and a sleeve 19 is slidably connected to the side of the inner drive shaft 3 through the guide bar 18. The vibration protrusion 4 is evenly fixed on the side of the sleeve 19 in a ring shape. The sleeve 19 slidably arranged on the side of the inner drive shaft 3 can be adjusted to the installation position accordingly, thereby changing the density of the vibration protrusion 4 facing the blade 2, thereby realizing the adjustment of different vibration frequencies of the blade 2 under the same rotation speed of the inner drive shaft 3.

[0057] According to the attached Figure 6 As shown, due to the installation of the side reinforcement rod 16 and the support block 17 of the inner drive shaft 3, the side sleeve 19 of the inner drive shaft 3 cannot be installed continuously. The technicians in this field insert a positioning rod 20 on the inner side of the inner drive shaft 3, and a positioning pin 21 is inserted on the side of the positioning rod 20. The positioning pin 21 passes through the sleeve 19 and is slidably connected to the inner drive shaft 3.

[0058] When the density of the vibration bumps 4 needs to be adjusted, the advance rod 20 is pushed, and the advance rod 20 synchronously drives multiple discontinuous sleeves 19 to slide equidistantly along the inner drive shaft 3 through the positioning pin 21, thereby achieving synchronous adjustment of the density of multiple groups of vibration bumps 4.

[0059] The vibration drag reduction and energy saving device of the rotary tiller uses an independently powered inner drive shaft 3 arranged on the inner side of the mounting shaft 1 to perform directional vibration driving on the blade 2. On the one hand, the power loss problem caused by driving all the blades 2 to vibrate at the same time is avoided. On the other hand, the blade 2 is driven to vibrate in a targeted manner along the radial direction of the mounting shaft 1 to avoid power loss caused by disordered vibration. When the mounting shaft 1 and the inner drive shaft 3 rotate at different frequencies, the vibration protrusion 4 periodically pushes the blade 2 to advance along the radial direction of the mounting shaft 1, and cooperates with the reset spring 5 to achieve a small range of vibration. The small range of vibration of the blade 2 in contact with the soil is beneficial to drag reduction and energy saving.

[0060] Furthermore, the blade 2 is slidably installed on the side of the mounting shaft 1 through the cooperation of the end cover 7 and the mounting sleeve 6, and a spring is provided to press the blade 2 against the inner bottom of the mounting sleeve 6. When the inner driving shaft 3 performs vibration driving on the blade 2, the effect will not be affected by the attenuation of the elastic coefficient of the reset spring 5, and the elastic force of the reset spring 5 ensures that the blade 2 is stably installed on the side of the mounting shaft 1, thereby avoiding the problem of the blade 2 being loosely installed and easily damaged.

[0061] Furthermore, the inner drive shaft 3 is slidably set on the inner side of the mounting shaft 1 through the slide rail 14, and the amplitude of the vibration of the blade 2 can be adjusted by adjusting the mounting position of the inner drive shaft 3. As the position of the inner drive shaft 3 changes, the distance between the vibration protrusion 4 installed on the side of the inner drive shaft 3 and the inner wall of the mounting shaft 1 also changes, and then the driving distance of the vibration protrusion 4 to the lever 12 also changes accordingly.

[0062] Furthermore, in order to ensure the stable vibration driving effect of the inner drive shaft 3 on the blade 2, a reinforcing rod 16 is also provided on one side of the inner drive shaft 3. The reinforcing rod 16 supports the middle section of the inner drive shaft 3 through multiple groups of support blocks 17 to ensure the strength of the inner drive shaft 3. In addition, the vibration protrusion 4 is slidably arranged on the side of the inner drive shaft 3 through the sliding sleeve 19, and the side of the sliding sleeve 19 is provided with vibration protrusions 4 with different density ranges. By adjusting the sliding sleeve 19 interval facing the blade 2, the vibration frequency can also be adjusted on the basis of a certain rotation speed.

[0063] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
