Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to an intelligent mower with anti-accumulation function. BACKGROUND

[0002] In the field of lawn maintenance, the working efficiency and lawn finishing effect of the mower as the core equipment directly affect the maintenance quality. With the development of intelligent technology, the mower gradually upgrades to automation and high efficiency, evolving from the traditional manual push type to mechanization and integrated operation, especially in the scenes of agricultural planting, municipal gardens, family courtyards, etc. Higher requirements are put forward for the grass cutting and processing capacity and smoothness of the mower - not only the high-efficiency cutting of weeds is needed, but also the accumulation of grass clippings should be avoided to hinder the subsequent operation, so as to ensure the continuous and stable lawn finishing effect.

[0003] The patent with publication number CN114982461B discloses an agricultural mechanized mower, which tries to solve the problem of grass clippings accumulation by setting a cutting part and a driving part in the front end of the machine body. Specifically, the cutting part of the device includes a chute, a first blade mechanism, a second blade mechanism, and a spiral blade: the second blade mechanism drives multiple second cutting blades arranged tangentially to rotate by relying on the first annular part, first cutting the weeds on the ground; the cut weeds enter the opening of the chute under the push of the push plate, and then the first blade mechanism drives the second connecting rod and the two first cutting blades to reciprocate by the push rod, further cutting the weeds into small pieces; at the same time, the gear assembly (gear ring, planetary gear, sun gear) of the driving part drives the sun gear coaxial fan to rotate at high speed, generating airflow to blow the small pieces of weeds to one side of the machine body; the spiral blade on the outside can also block the stones from entering the blade mechanism and push them away from the driving path.

[0004] Although this scheme reduces the direct accumulation of weeds on the driving path of the machine body through the combination design of "secondary cutting + airflow blowing", and to some extent reduces the difficulty of operation for farmers, the core defect of this existing scheme is that the blowing direction of the grass clippings is fixed. When the mower moves from A end to B end, the airflow generated by the fan can blow the grass clippings to the ground on one side of the machine body that has been mowed (adapted to the direction of travel), but when the mower completes the journey and moves from B end to A end in reverse, since the airflow direction is not synchronized with the direction of travel, the grass clippings will still be blown to the original fixed side, which has become the ground that has not been mowed at this time. When the mower operates again in the area where the grass clippings are accumulated and not mowed, the accumulated grass clippings will increase the resistance to the movement of the machine.

[0032] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 11 As shown: An intelligent lawnmower with anti-accumulation function includes an anti-accumulation discharge mechanism for collecting and discharging chopped grass. The anti-accumulation discharge mechanism includes a housing 1, a feed trough 2, an air duct 3, a blower mechanism 4, a switch mechanism 5, and a guide trough 6. The housing 1 is divided into upper and lower cavities. The feed trough 2 is located in the upper cavity of the housing 1. The upper side of the feed trough 2 has a feed inlet, and both ends of the feed trough 2 have discharge outlets. Both ends of the lower side of the feed trough 2 have air inlets. The air duct 3 is located in the lower cavity of the housing 1. Both ends of the air duct 3 have air inlets, and both ends of the upper side of the air duct 3 have air outlets, which are connected to the two air inlets respectively. The blower mechanism 4 is located inside the air duct 3 and is used to blow high-speed airflow into the feed trough 2 through the air outlets and air inlets. The switch mechanism 5 is located inside the feed trough 2 and is used to control the opening and closing of the two discharge outlets and two air inlets on the feed trough 2. The guide trough 6 is connected to the feed inlet and is used to guide the chopped grass into the feed trough 2.

[0034] When the mower is set to move from south to north for harvesting, the discharge ports at both ends of the feed trough 2 face east and west respectively. Before the mower starts, the switching mechanism 5 closes the discharge port at the east-facing end of the feed trough 2 and opens the corresponding air inlet at that end. It also opens the discharge port at the west-facing end of the feed trough 2 and closes the corresponding air inlet at that end, preparing for the directional transport of airflow and shredded grass. Then, the mower begins to move from south to north. The shredded grass produced by cutting weeds falls from the feed port into the feed trough 2 under the guidance of the guide chute 6. Simultaneously, the blower mechanism 4 inside the air duct 3 starts, generating a high-speed airflow. After air is drawn in through the air inlets at both ends of the duct 3, it is blown at high speed into the material trough 2 through the air outlet connected to the upper side and the air inlet (east end) opened on the lower side of the trough 2. The high-speed airflow entering the material trough 2 forms a directional airflow field from east to west along the interior of the trough 2. The grass clippings falling from the inlet come into full contact with the high-speed airflow, are carried by the airflow and move along the airflow direction, and are finally discharged from the outlet opened at the west end of the material trough 2, falling onto the ground that has been harvested behind the mower. When the mower completes the harvesting journey from south to north and needs to turn to harvest from north to south, the relative orientation of the outlets at both ends of the material trough 2 changes. The discharge outlet, originally facing east, is now facing to the right of the mower's direction of travel, and the discharge outlet, originally facing west, is now facing to the left. At this point, the open discharge outlet will be pointing towards the uncut area to the east. Before the mower begins harvesting from north to south, the switching mechanism 5 automatically closes the discharge outlet at the east-facing end of the feed trough 2 (uncut area) and simultaneously opens the corresponding air inlet. Conversely, it opens the discharge outlet at the west-facing end of the feed trough 2 (cut area) and simultaneously closes the corresponding air inlet, ensuring that the airflow direction always points towards the cut area. The mower then begins moving from north to south, and the blower mechanism 4 continues to operate, providing high-speed airflow. Air is blown into the feed trough 2 through the currently open air inlet, forming a stable east-to-west airflow field inside the feed trough 2. After the grass clippings fall into the feed trough 2, they are immediately carried by the airflow and discharged from the currently open western end outlet, falling into the already cut grass area. The switching mechanism 5 can adjust the state of the outlet and air inlet at both ends of the feed trough 2 in real time according to the change of the mower's travel direction, ensuring that the high-speed airflow generated by the blower mechanism 4 is always directed towards the already cut grass, so that the grass clippings are always discharged from the outlet facing the already cut grass area, thereby avoiding the accumulation of grass clippings in the uncut grass, and avoiding the accumulation of grass clippings causing the mower's cutting parts to jam and the cutting efficiency to decrease.

[0035] Reference Figure 3 and Figure 4 As shown: The blower mechanism 4 includes a fan assembly 41 and a switching mechanism; the fan assembly 41 is movably disposed inside the air duct 3; the switching mechanism is connected to the fan assembly 41 and is used to drive the fan assembly 41 to switch positions between two air outlets.

[0036] Specifically, the fan assembly 41 includes a housing 412, fan blades 411, and a first rotary driver 413. The housing 412 is connected to a switching mechanism, the fan blades 411 are disposed inside the housing 412, and the first rotary driver 413 is connected to the fan blades 411.

[0037] If the blower mechanism 4 is fixed in position within the air duct 3, then a certain distance is maintained between the blower mechanism 4 and both air outlets. The high-speed airflow provided by the blower mechanism 4 will experience some loss when it reaches the air outlets. Therefore, a fan assembly 41 and a switching mechanism are provided. When the mower is harvesting from south to north, the outlet of the feed trough 2 facing west opens, while the corresponding air inlet closes. Simultaneously, the outlet of the feed trough 2 facing east closes, and the corresponding air inlet opens. The switching mechanism drives the fan assembly 41 to move to the air outlet corresponding to that air inlet. At this time, the cover 412 in the fan assembly 41 is placed over the air outlet. The first rotary actuator drives the fan blade 411 to rotate, blowing high-speed airflow towards the air outlet. When the mower turns to harvest from north to south, the states of the discharge port and air inlet at both ends of the feed trough 2 change. The switching mechanism then moves the fan assembly 41 to the open air inlet. By changing the position of the fan assembly 41 through the switching mechanism, it connects to different air inlets. The high-speed airflow is conveyed upward through the air outlet with almost no diffusion loss, thereby ensuring a stable airflow and concentrated thrust to push the shredded grass towards the discharge port.

[0038] Reference Figure 4 and Figure 5 As shown: The switching mechanism includes a first guide component 42 and a linear drive component 43; the first guide component 42 is arranged along the length of the air duct 3 and is used to fix the moving direction of the fan component 41; the linear drive component 43 is used to drive the fan component 41 to move along the first guide component 42.

[0039] Specifically, the first guide assembly 42 includes at least two first guide rods 421, which are respectively disposed on both sides of the cover 412, and each of the two first guide rods 421 is slidably provided with a slider 422, which is connected to the cover 412.

[0040] When the mower is harvesting from south to north, the switching mechanism 5 opens the air inlet at the east end of the feed trough 2 and closes the air inlet at the west end. The linear actuator assembly 43 applies a thrust to the fan assembly 41 towards the east end. Under the action of the thrust, the cover 412 of the fan assembly 41 drives the sliders 422 on both sides to slide synchronously along the two first guide rods 421 of the first guide assembly 42. The double limit ensures that the fan assembly 41 does not deviate or tilt during the movement and always maintains a parallel and corresponding posture with the air outlet. When the mower is harvesting from north to south, the switching mechanism 5 opens the original air inlet at the west end of the feed trough 2 and closes the original air inlet at the east end. The linear actuator assembly 43 pushes the fan assembly 41 to move in the opposite direction along the first guide rod 421. By switching the position of the fan assembly 41 through the linear actuator assembly 43, airflow supply in different directions is realized.

[0041] Reference Figure 4 and Figure 6 As shown: The linear drive assembly 43 includes a connecting block 431 and a linear motion assembly 432; there are two connecting blocks 431, which are respectively connected to the two ends of the fan assembly 41; the linear motion assembly 432 is used to drive the two connecting blocks 431 to move synchronously.

[0042] If the fan assembly 41 is subjected to force on one side during movement, it may cause asynchronous movement of various parts of the fan assembly 41, resulting in increased friction between the fan assembly 41 and the first guide rod 421. By setting two connecting blocks 431 and a linear motion component 432, when the fan assembly 41 needs to be driven to move, the linear motion component 432 simultaneously drives the two connecting blocks 431 to move. The two connecting blocks 431 synchronously apply a pushing force to the fan assembly 41. At this time, both ends of the fan assembly 41 are synchronously subjected to a pushing force parallel to the first guide rod 421, so that all parts of the fan assembly 41 maintain synchronous movement. The driving force is synchronously transmitted through the two connecting blocks 431, so that both ends of the fan assembly 41 are always uniformly stressed without tilting or offsetting. The slider 422 and the first guide rod 421 maintain uniform contact, thereby solving the problem of excessive local friction caused by the first guide rod 421 being subjected to force on one side.

[0043] Reference Figure 4 and Figure 6 As shown: The linear motion assembly 432 includes two first rotating shafts 4321, two first synchronous belts 4323, and a second rotary driver 4324; both ends of the first rotating shafts 4321 are provided with first transmission wheels 4322; both ends of the first synchronous belts 4323 are respectively sleeved on the first transmission wheels 4322 at the same end of the two first rotating shafts 4321, and the first synchronous belts 4323 move with the connecting block 431; the second rotary driver 4324 is connected to the first rotating shafts 4321.

[0044] When the second rotary driver 4324 is started, it drives one of the first shafts 4321 to rotate. The first shaft 4321 drives the two first transmission wheels 4322 at both ends to rotate synchronously. The first transmission wheels 4322 drive the first transmission wheels 4322 on the other shaft 4321 to rotate via the first synchronous belt 4323. At this time, the two first synchronous belts 4323 move at the same speed and in the same direction. The two connecting blocks 431 connected to the two first synchronous belts 4323 also move at the same speed and in the same direction, thereby achieving uniform and synchronous force on both ends of the cover 412 in the fan assembly 41.

[0045] Reference Figure 2 , Figure 3 and Figure 7 As shown: The switching mechanism 5 includes two switching components 51 and a synchronous drive mechanism 52; the two switching components 51 are respectively arranged at both ends inside the material trough 2. The switching components 51 are used to control the opening of one of the material outlet and air inlet at one end of the material trough 2; the synchronous drive mechanism 52 is used to drive the two switching components 51 to move synchronously.

[0046] When the mower completes its south-to-north harvesting journey and needs to switch to north-to-south harvesting, the initial state is as follows: the western end switch assembly 51 of the feed trough 2 is in the "discharge port open, air inlet closed" state (clods of grass are discharged from the western end), and the eastern end switch assembly 51 of the feed trough 2 is in the "discharge port closed, air inlet open" state. The synchronous drive mechanism 52 synchronously drives the two switch assemblies 51 to work. The switch assembly 51 that originally closed the discharge port and opened the air inlet will open the discharge port and close the air inlet, completing the switch from "air inlet end" to "discharge port". The switch assembly 51 that originally opened the discharge port and closed the air inlet will close the discharge port and open the air inlet, completing the switch from "discharge port" to "air inlet". By driving the two switch assemblies 51 to act synchronously through the synchronous drive mechanism 52, the time delay caused by traditional asynchronous switching is avoided, and the switching of the discharge port and air inlet state at both ends of the feed trough 2 can be completed in a short time, thereby reducing the time for switching the working state of the mower.

[0047] Reference Figure 8 and Figure 9 As shown: The switch assembly 51 includes a first cover plate 511, a second cover plate 512, and a switch linkage assembly 513; the first cover plate 511 has a second rotating shaft 5111 rotatably connected to the material trough 2 in the middle, and the first cover plate 511 is used to cover the discharge port; the second cover plate 512 is used to cover the air inlet; the switch linkage assembly 513 is used to link the movement of the first cover plate 511 and the second cover plate 512.

[0048] Initially, the first cover plate 511 is vertical and completely covers the outlet of the material trough 2. At this time, the second cover plate 512, under the traction of the switch linkage assembly 513, is positioned away from the air inlet, and the air inlet is fully open, allowing airflow to enter the material trough 2 normally. The synchronous drive mechanism 52 is activated, applying a positive rotational force to the second rotating shaft 5111. The second rotating shaft 5111 drives the first cover plate 511 to rotate synchronously in the positive direction around its own axis. As the first cover plate 511 rotates, its edge applies a force to the second cover plate 512 through the switch linkage assembly 513, causing the second cover plate 512 to rotate. 12 moves towards the air inlet. When the first cover plate 511 rotates around the second rotating shaft 5111 to a horizontal state, the switch linkage assembly 513 drives the second cover plate 512 to move to a position that is completely in contact with the air inlet. When the synchronous drive mechanism 52 drives the second rotating shaft 5111 to rotate in the opposite direction, the first cover plate 511 rotates in the opposite direction, and the switch linkage assembly 513 drives the second cover plate 512 to move in the opposite direction. The switch linkage assembly 513 makes the first cover plate 511 and the second cover plate 512 move synchronously, thereby ensuring that one of the outlet and the air inlet at one end of the material trough 2 is open and the other is closed.

[0049] Reference Figure 8 and Figure 9 As shown: At least two sliding grooves are provided on the second cover plate 512, and the switch linkage assembly 513 includes a connecting rod 5132 and at least two second guide rods 5131; the two ends of the connecting rod 5132 are respectively hinged to the first cover plate 511 and the second cover plate 512; the two second guide rods 5131 correspond to the two sliding grooves on the second cover plate 512 respectively.

[0050] In the initial state, the first cover plate 511 vertically covers the discharge port, and the second cover plate 512 is positioned away from the air inlet under the traction of the connecting rod 5132, with the air inlet fully open. When the first cover plate 511 rotates, it applies a pulling force to the second cover plate 512 through the connecting rod 5132. Under the pulling force of the connecting rod 5132, the sliding grooves on both sides of the second cover plate 512 slide along the corresponding second guide rods 5131. Since the second guide rods 5131 are fixed and parallel to the translation direction, the sliding grooves are forcibly restricted in the axial direction of the second guide rods 5131 during the sliding process, preventing the second cover plate 512 from lifting upward or shifting downward due to uneven force. At the same time, the two symmetrical second guide rods 5131 and the sliding grooves restrain each other, preventing the second cover plate 512 from tilting left or right or twisting during movement, ensuring that the second cover plate 512 always maintains a horizontal posture and moves closer to the air inlet, thereby avoiding the second cover plate 512 shifting and failing to completely cover the air inlet.

[0051] Reference Figure 7 and Figure 10As shown: The synchronous drive mechanism 52 includes two second transmission wheels 521, a second synchronous belt 522 and a drive wheel 523; the two second transmission wheels 521 are respectively connected to two second rotating shafts 5111; the two ends of the second synchronous belt 522 are respectively sleeved on the two second transmission wheels 521; the drive wheel 523 is connected to the second synchronous belt 522 in a transmission manner, and a third rotary driver 524 is provided on one side of the drive wheel 523.

[0052] When it is necessary to change the state of the air inlets at both ends of the material trough 2, the third rotary driver 524 drives the drive wheel 523 to rotate. The drive wheel 523 drives the second synchronous belt 522 to rotate, so that the second synchronous belt 522 forms a ring transmission. The two ends of the second synchronous belt 522 move in opposite directions, so the two second transmission wheels 521 rotate in opposite directions. Driven by the downward moving second synchronous belt 522, the second transmission wheel 521 rotates in the opposite direction around the second rotating shaft 5111 and drives the second rotating shaft 5111 to rotate counterclockwise synchronously. Driven by the upward moving second synchronous belt 522, the second transmission wheel 521 rotates in the forward direction around the second rotating shaft 5111 and drives the second rotating shaft 5111 to rotate clockwise, thereby realizing the synchronous reverse action of the first cover plate 511 of the two switch components 51, and the opening and closing of the air inlet are completely synchronized.

[0053] Reference Figure 3 and Figure 11 As shown: Both the air inlet and the air outlet are equipped with a grille 31 to prevent grass clippings from entering the air duct 3.

[0054] After the fan assembly 41 is started, the fan blades 411 rotate at high speed, generating suction on the air outside the air duct 3, causing the outside air to flow into the air duct 3 quickly through the air inlets at both ends of the air duct 3. At this time, impurities such as grass mixed in the air move towards the air inlet with the airflow. However, since a grid mesh 31 is set at the air inlet, the impurities are blocked by the mesh of the grid mesh 31 and cannot enter the air duct 3. At the same time, during the opening and closing of the discharge port of the material trough 2, a small amount of grass may fall due to inertia or airflow disturbance and move towards the air inlet of the material trough 2. At this time, the grid mesh 31 at the air outlet of the air duct 3 plays a blocking role. The fallen grass is intercepted by the grid mesh 31 on one side of the material trough 2 and cannot enter the air duct 3 through the air outlet of the air duct 3, thereby preventing impurities from entering the air duct 3 and affecting the operation of the fan assembly 41.

[0055] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention.
