Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to an automatic positioning beater. Background Art

[0002] Rice is one of the common crops and one of the important food crops for mankind. It has a long history of cultivation and consumption. During the rice planting process, farmland needs to go through multiple treatments to ensure the normal growth and development of rice. Pulping is one of the treatment processes. Pulping refers to the process of plowing, crushing, and leveling the soil of the rice field by mechanical or manual means during the rice planting process, and mixing it with water to form a muddy state, so as to facilitate the subsequent transplanting and crop growth. This process not only improves the soil structure, but also improves the soil's ability to retain water and fertilizer. In large-scale rice planting, pulping is generally done mechanically. The pulper is installed on a tractor, and the tractor carries the pulper to pulp the entire farmland.

[0003] In the prior art, after the existing beater is installed on the tractor, its beating depth is fixed. However, some farmlands are not "flat" and there may be lower or higher places. At this time, the beater with a fixed height cannot perform good beating operations in these places. If the beater is stopped for height adjustment, the beating efficiency will be greatly affected. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to propose an automatic positioning beater.

[0008] Furthermore, the position adjustment mechanism also includes two monitoring grooves, which are opened in the baffle cover, and a rotating column is rotatably connected between the two opposite inner walls of the monitoring groove through a bearing, and a resistance plate is fixedly connected to the rotating column, and a fixed plate is fixedly connected between the two opposite inner walls of the monitoring groove, and a first spring is fixedly connected between the resistance plate and the fixed plate, and a pressure sensor is fixedly connected to the side wall of the fixed plate close to the resistance plate, and the pressure sensor is connected to the electric clutch through a PLC control circuit.

[0009] Furthermore, the side wall of the baffle plate is provided with a leveling mechanism, and the leveling mechanism includes a plurality of side rods, the side rods are fixedly connected to the side wall of the baffle plate, the ends of the side rods away from the baffle plate are fixedly connected to a second spring, and the second springs are jointly fixedly connected to a leveling plate, and the end of the rotating shaft located outside the fixed block passes through and is fixedly connected to a sleeve, the side wall of the sleeve is fixedly connected to a connecting rod, and the connecting rod is fixedly connected to the upper surface of the leveling plate.

[0010] Furthermore, a beating mechanism is provided in the baffle cover, and the beating mechanism includes a beating rod, and the beating rod is rotatably connected to the fixed block through a bearing, and both ends of the beating rod extend through the outside of the fixed block and are rotatably connected to the two inner walls opposite to the beating groove through bearings, and one end of the beating rod located inside the fixed block is fixedly connected to a second bevel gear, and the second bevel gear is meshed with the first bevel gear, and the beating rod is fixedly connected to two driving cylinders, and the driving cylinder is rotatably connected to a plurality of rotating wheels through bearings, and a plurality of functional rods are fixedly connected between the two inner side walls opposite to the rotating wheel, and the functional rod is rotatably connected to a resist block through a bearing, and a third spring is fixedly connected between the resist block and the inner side wall of the rotating wheel, and a plurality of top blocks are fixedly connected to the side wall of the driving cylinder, and the top blocks correspond to the rotating wheels one by one, and a plurality of beating sheets are fixedly connected to the outer side wall of the rotating wheel.

[0011] Furthermore, a plurality of pressure tanks are fixedly connected to the upper surface of the screed plate, the pressure tanks are filled with pigment, a fixed pipe is fixedly connected through the pressure tanks and the screed plate, a solenoid valve is arranged in the fixed pipe, and the solenoid valve is electrically connected to the corresponding resistance block and top block through a wire.

[0012] Furthermore, the baffle cover is rotatably connected to a synchronization rod through a bearing, and the synchronization rod extends through the corresponding monitoring groove and is fixedly connected to the corresponding side wall of the rotating column.

[0013] Further, the number of teeth of the first bevel gear is greater than the number of teeth of the second bevel gear.

[0014] The present invention has the following advantages:

[0015] 1. During the beating process, the driving motor drives the worm to rotate, so that the worm wheel meshing with it rotates, and the worm wheel drives the two second gears to rotate through the rotating shaft. Then, by energizing the electric clutch and controlling the clutch state between it and the rotating shaft, the first gear can be controlled to rotate in different directions. The rotation of the first gear drives the piston to move through the threaded connection between the threaded barrel and the screw, thereby adjusting the height of the beater, so that the beater can be adjusted in height during operation without stopping for adjustment, which greatly improves the beating efficiency;

[0016] 2. During the beating process, the beater will move forward and drive the resistance plate forward together. The height of the beater determines the depth of the resistance plate into the mud. As the depth increases, the resistance of the resistance plate also increases, which increases the pressure on the pressure sensor. The pressure sensor senses the pressure and controls the two electric clutches through the PLC circuit, so that the beater can be automatically positioned according to the beating depth, ensuring that the same beating depth can be achieved at higher and lower heights, thereby ensuring the beating effect.

[0017] 3. During the beating process, the rear screed plate moves with the beater to level the surface of the mud after beating. During the beating process, the operation of the motor will inevitably generate a certain vibration, which is transmitted to the screed plate through the fixed block, shaft, sleeve, and connecting rod, so that the screed plate levels the mud under a certain vibration state, greatly improving the leveling effect and ensuring the uniformity of the mud surface after leveling;

[0018] 4. The leveling effect is improved through the vibration of the motor, and at the same time, the vibration of the motor is suppressed to a certain extent, thereby increasing the service life of the motor;

[0019] 5. The rotating wheel and the driving cylinder are not rigidly connected. When the rotating wheel rotates to drive the beating blade to rotate for beating, when encountering hard debris (such as stones), the top block will overcome the elastic force of the third spring, so that the stop block rotates and passes over the stop block, and the rotating wheel does not rotate at this time, thereby avoiding the beating blade from still rotating when encountering hard debris, resulting in damage to the beating blade;

[0020] 6. When encountering a hard object, the wheel stops rotating, the top block passes over the resistance block, separates from the resistance block and is located between the two resistance blocks. At this time, the corresponding solenoid valve is in the power-off open state, and the paint in the pressure tank will be discharged to mark the hard object, which makes it easier for subsequent staff to uniformly handle the hard objects in the farmland.

[0030] Reference Figure 1-8 A beater with automatic positioning comprises a baffle 1, a beating groove 29 is provided in the baffle 1, a fixed block 2 is penetrated and fixedly connected to the baffle 1, the fixed block 2 is a hollow structure, a connecting tube 3 is penetrated and fixedly connected to the side wall of the fixed block 2, a fixed column 4 and a piston 10 are sealed and slidably connected in the connecting tube 3, hydraulic oil is filled between the fixed column 4 and the piston 10, a driving motor 5 is fixedly connected to the upper surface of the fixed block 2 through a bracket, a driving shaft 6 is fixedly connected to the output shaft of the driving motor 5, the driving shaft 6 is rotatably connected to the top wall of the fixed block 2 through a bearing and extends to the inside thereof, and a position adjustment mechanism is arranged in the fixed block 2.

[0031] The position adjustment mechanism includes a mounting block 7, which is fixedly connected to the inner wall of the fixed block 2 through a rod. The mounting block 7 is rotatably connected to a threaded barrel 8 through a bearing, and the threaded barrel 8 is fixedly connected to a first gear 11. The threaded barrel 8 is internally threaded with a screw 9, and the thread lifting of the screw 9 is less than the equivalent friction angle of the spiral pair formed by the threaded barrel 8 and the screw 9, so that the threaded connection is self-locking, ensuring that the height of the beater will not change when it is not adjusted. The screw 9 extends into the connecting barrel 3 and is fixedly connected to the side wall of the piston 10. The drive shaft 6 is fixedly connected to a worm 12 and the first bevel gear 30, the fixed block 2 is rotatably connected to two rotating shafts 13 through bearings, both ends of the rotating shaft 13 extend through and extend to the outside of the fixed block 2, a section of the rotating shaft 13 located in the fixed block 2 is fixedly connected to a worm wheel 14, the worm wheel 14 is meshed with the worm 12, and the two worm wheels 14 are symmetrically arranged, so that the rotation of the worm 12 drives the two worm wheels 14 to rotate in opposite directions, and the unfolded helix angle of the worm 12 is smaller than the friction angle of the contact surface between the worm wheel 14 and the worm 12, thereby ensuring the self-locking of the meshing of the worm wheel 14 and the worm 12, so that the worm wheel 14 can only be driven by the worm 12 The rotating shaft 13 is located in the fixed block 2 and is rotatably connected to an electric clutch 15 through a bearing. The electric clutch 15 can be combined with the rotating shaft 13 when the power is on, and disconnected from the rotating shaft 13 when the power is off. The electric clutch 15 is fixedly connected to the second gear 16, and the second gear 16 is meshed with the first gear 11. The driving motor 5 rotates to drive the driving shaft 6 to rotate, thereby driving the worm 12 to rotate. The worm 12 drives the two worm wheels 14 meshed with it to rotate. The rotation of the worm wheel 14 drives the corresponding rotating shaft 13 to rotate, so that the two rotating shafts 13 rotate in opposite directions. Since one of the electric clutches 15 is in power-on rotation, the corresponding rotating shaft 13 drives the second gear 16 to rotate, and the second gear 16 drives the first gear 11 meshing therewith to rotate, and the rotation of the first gear 11 drives the threaded tube 8 to rotate, thereby driving the screw 9 to move through the threaded connection, so that the piston 10 slides toward the inside of the connecting tube 3, and then the fixed column 4 slides toward the outside of the connecting tube 3, so that the baffle 1 and the fixed block 2 are lowered as a whole, so that the beater can adjust the height during operation without stopping for height adjustment, which greatly improves the beating efficiency.

[0032] The position adjustment mechanism also includes two monitoring grooves 17, which are opened in the baffle 1. A rotating column 18 is rotatably connected between the two opposite inner side walls of the monitoring groove 17 through a bearing. A resistance plate 19 is fixedly connected through the rotating column 18. A fixing plate 20 is fixedly connected between the two opposite inner side walls of the monitoring groove 17. A first spring 21 is fixedly connected between the resistance plate 19 and the fixing plate 20. A pressure sensor 22 is fixedly connected to the side wall of the fixing plate 20 close to the resistance plate 19. As the depth of the resistance plate 19 inserted into the mud is different, the pressure it is subjected to is different, so that the pressure acting on the pressure sensor 22 is also different. The beating depth is monitored by the size of the pressure. The pressure sensor 22 is connected to the electric clutch 15 through a PLC control circuit. The pressure sensor 22 can sense the pressure it is subjected to and control the on and off of the two electric clutches 15 according to the size of the pressure through the PLC control circuit. When the depth is deep, the height is automatically increased, and when the depth is shallow, the height is automatically decreased until a minimum is reached. Optimal depth, at this time the pressure is in a fixed range, within this range, both electric clutches 15 are not energized, pressure sensor 22 and PLC circuit are both existing technologies, which will not be elaborated here, during the beating process, if the mud height changes, when the mud height increases, the depth of the resistance plate 19 inserted into the mud becomes deeper accordingly, thereby increasing the resistance it encounters when moving forward, and when the resistance increases, the pressure of the resistance plate 19 on the pressure sensor 22 increases accordingly, and at this time the pressure sensor 22 energizes another electric clutch 15, and at this time the other rotating shaft 13 can drive the corresponding second gear 16 to rotate, thereby reversing the first gear 11, causing the piston 10 to slide toward the outside of the connecting tube 3, thereby increasing the height of the beater until it increases to the depth at which the resistance plate 19 is inserted into the mud to the required depth, conversely, if the mud height decreases, the height of the beater is reduced, ensuring that no matter how high the beating is, a certain beating depth can be guaranteed, thereby completing automatic positioning beating and ensuring a good beating effect.

[0033] A leveling mechanism is provided on the side wall of the baffle cover 1, and the leveling mechanism includes a plurality of side rods 26, and the side rods 26 are fixedly connected to the side wall of the baffle cover 1, and one end of the side rods 26 away from the baffle cover 1 is fixedly connected to a second spring 27, and the second spring 27 is jointly fixedly connected to a leveling plate 25, and one end of the rotating shaft 13 located outside the fixed block 2 passes through and is fixedly connected to a sleeve 23, and the side wall of the sleeve 23 is fixedly connected to a connecting rod 24, and the connecting rod 24 is fixedly connected to the upper surface of the leveling plate 25. During the operation of the driving motor 5, a certain vibration is bound to be generated, and the vibration is transmitted to the fixed block 2 through the bracket, and the rotating shaft 13 is connected to the fixed block 2, and the rotating shaft 13 will vibrate together with the fixed block 2, and the vibration is then transmitted to the leveling plate 25 by the sleeve 23 and the connecting rod 24, so that the leveling plate 25 generates a certain vibration, and leveling while vibrating can ensure that the mud surface after leveling is more uniform and flat, and leveling by the vibration of the driving motor 5 can also suppress the vibration of the driving motor 5 to a certain extent, protect the motor to a certain extent, and save energy.

[0034] A beating mechanism is provided in the baffle 1, and the beating mechanism includes a beating rod 31, and the beating rod 31 is rotatably connected to the fixed block 2 through a bearing, and both ends of the beating rod 31 extend through the outside of the fixed block 2 and are rotatably connected to the two inner side walls opposite to the beating groove 29 through bearings, and one end of the beating rod 31 located inside the fixed block 2 is fixedly connected with the second bevel gear 28, and the second bevel gear 28 is meshed with the first bevel gear 30, and the number of teeth of the first bevel gear 30 is greater than the number of teeth of the second bevel gear 28, so that the beating rod 31 is driven by the driving motor 5 more quickly The beating rod 31 is fixedly connected to two driving cylinders 32 through a bearing, and the two driving cylinders 32 are symmetrically arranged about the fixed block 2. The driving cylinder 32 is rotatably connected to a plurality of rotating wheels 33 through a bearing. The rotating wheels 33 are hollow and inwardly open structures, and the surfaces of the rotating wheels 33 and the driving cylinder 32 are coated with an insulating layer to ensure their insulation performance. A plurality of functional rods 34 are fixedly connected between two opposite inner side walls of the rotating wheel 33. The functional rods 34 are rotatably connected to a stop block 35 through a bearing, and the stop block 35 is fixedly connected to the inner wall of the rotating wheel 33 There is a third spring 36, and a plurality of top blocks 37 are fixedly connected to the side wall of the driving cylinder 32. The top blocks 37 correspond to the rotating wheels 33 one by one. There is a top block 37 in each rotating wheel 33. The top blocks 37 and the stop blocks 35 are both made of steel and have conductivity. A plurality of beating blades 38 are fixedly connected to the outer side wall of the rotating wheel 33. If the beating blades 38 encounter a hard substance during beating, the beating blades 38 contact the hard substance, thereby hindering the rotation of the beating blades 38. At this time, the driving cylinder 32 is still in a rotating state, and the top blocks 37 are still moving. At this time, the top blocks 37 are against the stop blocks 35. 5, the thrust of the stop block 35 will cause the stop block 35 to overcome the elastic force of the third spring 36 and rotate, and as the stop block 35 rotates, the top block 37 will pass over the stop block 35, so that the rotating wheel 33 no longer rotates with the rotation of the driving cylinder 32 until the beating blade 38 passes over the hard object. At this time, the rotation of the rotating wheel 33 is no longer hindered, and the top block 37 contacts with the stop block 35, and the rotating wheel 33 can continue to be driven to rotate by the thrust, thereby preventing the beating blade 38 from continuing to rotate after encountering a hard object, which may cause damage to the beating blade 38, and the beater has a certain self-protection function.

[0035] A plurality of pressure tanks 39 are fixedly connected to the upper surface of the screed plate 25. The pressure tanks 39 are filled with pigments. The pigments are plant pigments to prevent the pigments from affecting the soil. The pigments are filled in the pressure tanks 39 at a certain pressure so that they can be automatically sprayed out. The pressure tanks 39 and the screed plate 25 are connected to a fixed pipe 40 through which a solenoid valve 41 is arranged. The solenoid valve 41 is an open solenoid valve. It is closed when the power is on and opened when the power is off. The solenoid valve 41 is electrically connected to the corresponding abutment block 35 and the top block 37 through a wire and is located on the same runner 3. The block 35 in 3 is connected to the negative pole of the power supply, and the top block 37 is connected to the positive pole of the power supply and then connected to the solenoid valve 41. After the top block 37 contacts any one of the blocks 35, the solenoid valve 41 can be energized. When the top block 37 passes over the block 35, the top block 37 does not contact any block 35, so that the corresponding solenoid valve 41 is de-energized. At this time, the paint in the corresponding pressure tank 39 will be sprayed out through the fixed tube 40, marking the place to remind the staff that there is a hard object here, which is more convenient for subsequent staff to clean up the hard object.

[0036] It should be noted that another electric valve is also provided at the fixed pipe 40, and the electric valve opens when the whole beater is powered on and closes when the power is off.

[0037] The baffle 1 is rotatably connected to a synchronization rod 42 through a bearing. The synchronization rod 42 extends into the corresponding monitoring slot 17 and is fixedly connected to the side wall of the corresponding rotating column 18. The setting of the synchronization rod 42 synchronizes the rotation of the two rotating columns 18, thereby more accurately reflecting the height of the beating point at this time.

[0038] In the present invention, the fixing column 4 is connected to the tractor body, and then the driving motor 5 is turned on, and the tractor is started to move forward. At this time, since the resistance plate 19 is not inserted into the mud, it will not contact the pressure sensor 22. When the pressure sensor 22 is not subjected to pressure or the pressure does not reach the set value, one of the electric clutches 15 will be energized, so that the electric clutch 15 is combined with the rotating shaft 13.

[0039] The rotation of the driving motor 5 drives the driving shaft 6 to rotate, thereby driving the worm 12 to rotate, and the worm 12 drives the two worm wheels 14 meshing with it to rotate, and the rotation of the worm wheel 14 drives the corresponding rotating shaft 13 to rotate, so that the two rotating shafts 13 rotate in opposite directions. Since one of the electric clutches 15 is in power-on rotation, the corresponding rotating shaft 13 drives the second gear 16 to rotate, and the second gear 16 drives the first gear 11 meshing with it to rotate. The rotation of the first gear 11 drives the threaded tube 8 to rotate, thereby driving the screw 9 to move through the threaded connection, so that the piston 10 slides toward the inside of the connecting tube 3, and then the fixed column 4 slides toward the outside of the connecting tube 3, so that the baffle 1 and the fixed block 2 are lowered as a whole until the beating sheet 38 is inserted into the mud. When it is inserted to the required depth, the pressure on the pressure sensor 22 is within the set range, so that the two electric clutches 15 are both powered off, and the height of the beater no longer changes.

[0040] At the same time, the driving shaft 6 drives the first bevel gear 30 to rotate, the first bevel gear 30 drives the second bevel gear 28 meshing with it to rotate, the second bevel gear 28 drives the beating rod 31 to rotate, and the beating rod 31 drives the driving cylinder 32 to rotate, so that the top block 37 on the driving cylinder 32 rotates with it. During the rotation of the top block 37, it contacts the stop block 35 and pushes the stop block 35 to move, so that the rotating wheel 33 rotates. The rotation of the rotating wheel 33 beats the farmland through the beating blade 38.

[0041] During the beating process, if the mud height changes, when the mud height increases, the depth of the resistance plate 19 inserted into the mud becomes deeper accordingly, so that the resistance it encounters when moving forward becomes larger. After the resistance increases, the pressure of the resistance plate 19 on the pressure sensor 22 increases accordingly. At this time, the pressure sensor 22 energizes another electric clutch 15. At this time, the other rotating shaft 13 can drive the corresponding second gear 16 to rotate, so that the first gear 11 reverses, and the piston 10 slides toward the outside of the connecting tube 3, thereby increasing the height of the beater until it increases to the required depth of the resistance plate 19 inserted into the mud. Conversely, if the mud height decreases, the height of the beater is lowered to ensure that no matter how high the beating is, a certain beating depth can be guaranteed, thereby completing automatic positioning beating.

[0042] After the beating is completed, the rear screed plate 25 will then level the beaten mud. The driving motor 5 will inevitably generate a certain vibration during operation, which is transmitted to the fixed block 2 through the bracket. The rotating shaft 13 is connected to the fixed block 2, and the rotating shaft 13 will vibrate along with the fixed block 2. The vibration is then transmitted to the screed plate 25 by the sleeve 23 and the connecting rod 24, causing the screed plate 25 to generate a certain vibration. Leveling while vibrating can ensure that the surface of the mud after leveling is more uniform and flat.

[0043] If the beating blade 38 encounters a hard object during beating, the beating blade 38 will contact the hard object, thereby hindering the rotation of the beating blade 38. At this time, the driving cylinder 32 is still in a rotating state, and the top block 37 is still moving. At this time, the thrust of the top block 37 on the resistance block 35 will cause the resistance block 35 to overcome the elastic force of the third spring 36 and rotate. As the resistance block 35 rotates, the top block 37 will pass over the resistance block 35, so that the rotating wheel 33 no longer rotates with the rotation of the driving cylinder 32 until the beating blade 38 passes over the hard object. At this time, the rotation of the rotating wheel 33 is no longer hindered, and the top block 37 is in contact with the resistance block 35, and can continue to drive the rotating wheel 33 to rotate through the thrust.

[0044] When the top block 37 passes over the stop block 35, the top block 37 does not contact any stop block 35, so that the corresponding solenoid valve 41 is powered off. At this time, the paint in the corresponding pressure tank 39 will be sprayed out through the fixed tube 40, marking the place to remind the staff that there is a hard object here, which makes it easier for subsequent staff to clean the hard object.
