Description

Technical Field

[0001] The invention relates to the technical field of conveying, and in particular to a rotary type grain-reaping machine. Background Art

[0002] Grain scrapers are mainly used for the collection, emptying, stacking and loading of bulk grain. This type of mechanical equipment can improve the efficiency of grain processing and reduce the intensity of manual labor. Small grain scrapers are suitable for use in small grain stations and individual industrial and commercial households. They are used to scrape grain for bag filling operations, or can be used in conjunction with other conveying machinery to form assembly line operations. They are very useful, especially in the process of grain procurement, storage, transshipment and transportation.

[0003] A Chinese patent document with announcement number CN220519599U discloses a grain scraper capable of filtering dust, including a grain scraper body, the grain scraper body consisting of a chassis, a feeding pipe installed on the chassis and a bucket installed at the lower end of the feeding pipe. A moving device is provided on the chassis, and the moving device is used to drive the frame to move. The grain scraper is also provided with a conveying device, and the conveying device includes a motor, an annular chain arranged in the feeding pipe and a feeding plate installed on the chain. A discharge port is opened at the upper end of the feeding pipe. When collecting and conveying grains, the moving device drives the frame to move, so that the bucket enters the grain pile, and the auger in the bucket conveys the grains to the feeding pipe in the middle of the bucket, and the feeding plate in the feeding pipe pushes the grains along the inner wall of the feeding pipe to the discharge port, thereby completing the collection and conveying of the grains.

[0004] In the above technology, since the grains contain a lot of dust, a lot of dust will be generated at the discharge port. During the operation of the small-scale grain scraper, a bucket cart needs to be equipped at the discharge port of the grain scraper. The bucket cart needs to be pushed manually to move with the grain scraper, resulting in high labor costs and greater harm to the staff caused by the dust. Summary of the invention

[0005] The present invention provides a rotary type grain scraper, aiming to solve the problem that a small grain scraper in the related art needs to be manually pushed by a bucket cart to follow the grain scraper, resulting in high labor costs and greater harm to workers caused by dust.

[0006] A rotary type hoeing machine comprises a hoeing machine body and a traction device, wherein the traction device comprises:

[0007] A mounting seat, which is installed on one side of the discharging port of the grain scraper;

[0008] A locking assembly, which is arranged on the mounting seat and is used to connect the mounting seat and the bucket truck together;

[0009] A detection assembly, the detection assembly comprising a slider mounted on a mounting seat for transverse sliding, a scraper elastically hinged on the slider, and a driving unit for driving the slider to slide transversely, and the scraper is located in an upper opening of the bucket truck;

[0010] An unlocking component is arranged on the mounting seat. When the bucket cart is full, the scraper is blocked by the material and deflected during reciprocating movement. When the deflection angle of the scraper is greater than 60 degrees, the unlocking component drives the locking component to move, thereby disconnecting the mounting seat and the bucket cart.

[0011] The effect is that the setting of the traction component can connect the grain scraper and the bucket cart together, and there is no need to manually push the bucket cart to move with the grain scraper, which reduces the harm of dust to the workers, and the scraper can scrape the materials in the bucket cart to make the materials in the bucket cart more flat.

[0012] Preferably, the locking assembly includes a push rod hinged on the mounting seat and a locking block slidably mounted on the mounting seat. A slot is provided on the push rod. When the push rod abuts against the outer side of the side wall where the handle of the push bucket truck is located, the locking block is inserted into the slot to lock the push rod.

[0013] The utility model has the effect of connecting the bucket truck and the grain scraper together.

[0014] Preferably, the unlocking assembly includes an unlocking rod slidably installed in a mounting seat and a push rod arranged on a scraper hinge shaft. The lower end of the unlocking rod is connected to the upper end of the locking block. When the deflection angle of the scraper is greater than 60 degrees, the push rod pushes the unlocking rod to move upward, thereby driving the locking block to disengage from the slot.

[0015] The effect thereof is that the connection between the rice scraper and the bucket pusher is disconnected after the materials in the bucket pusher reach a preset height.

[0016] Preferably, an elastic member is installed at the hinge shaft of the push rod to keep the push rod away from the side wall of the push bucket truck.

[0017] The effect is that it is used to automatically keep the push rod level after being unlocked.

[0018] Preferably, the unlocking rod and the mounting seat are connected via a second elastic member, and the second elastic member applies an elastic force to the unlocking rod to move downward and reset.

[0019] The effect is that the push rod is automatically locked after being reset.

[0020] Preferably, the driving unit includes a motor installed on the raking machine and a reciprocating screw rotatably installed in a mounting seat, the output end of the motor is connected to the input end of the reciprocating screw, and the slider is fixedly connected to a nut on the reciprocating screw.

[0021] Preferably, a pressure switch for controlling the start and stop of the motor is provided on the mounting seat. When the push rod is away from the side wall of the push bucket cart and the push rod is rotated to a horizontal position, the pressure switch is pressed to turn off the motor.

[0022] Preferably, a scraper rod extending along the width direction of the bucket truck is installed at the lower end of the scraper, and the scraper rod is used to scrape the material flat.

[0023] Preferably, the traction device also includes a baffle installed on the grain scraper, and the baffle abuts against the inclined surface of the bucket truck.

[0024] The effect is that it is used to improve the stability of the connection between the grain scraper and the bucket truck.

[0025] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0026] 1. By setting up a traction device to connect the bucket cart and the grain scraper together, the grain scraper can drive the bucket cart forward when it moves forward. There is no need to manually push the bucket cart to move with the grain scraper, reducing the harm of dust generated by the discharge port of the grain scraper to workers.

[0027] 2. The height of the material in the hopper cart is monitored by setting a detection component. The unlocking structure is set to disconnect the rice scraper and the hopper cart when the material height in the hopper cart reaches the preset value, and the motor is shut down to prevent the material in the hopper cart from overflowing due to negligence of the staff.

[0028] 3. The scraper can flatten the material in the bucket truck when it moves back and forth, preventing all the materials in the bucket truck from being concentrated in the middle to form a pointed pile, thereby improving the uniformity of material distribution in the bucket truck.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figure 1 As shown, a rotary type grain scraper according to an embodiment of the present invention comprises a grain scraper body 1 and a traction device, wherein the traction device connects a bucket cart 6 and the grain scraper together so that the bucket cart 6 can be driven forward when the grain scraper moves forward. When the material in the bucket cart 6 reaches a preset height, the traction device disconnects the bucket cart 6 and the grain scraper.

[0039] The traction device includes a mounting seat 2, a locking component 3, a detection component 4 and an unlocking component 5. The two mounting seats 2 are respectively installed on both sides of the discharging end of the grain scraper. The locking component 3 is arranged on the mounting seat 2 for connecting the mounting seat 2 and the push-bucket cart 6 together. The detection component 4 is arranged on the mounting seat 2 for detecting the height of the material in the push-bucket cart 6. The unlocking component 5 is arranged on the mounting seat 2. When the material height in the push-bucket cart 6 reaches a preset value, the unlocking component 5 unlocks the locking component 3, thereby disconnecting the connection between the mounting seat 2 and the push-bucket cart 6.

[0040] like Figure 2-Figure 3 As shown, both sides of the discharge port 12 of the feeding pipe 11 on the grain scraper are provided with mounting shafts arranged along the front-to-back direction, the left end of the mounting seat 2 is fixedly connected to the mounting shaft, the mounting seat 2 includes an L-shaped rod 21 and a mounting plate 22, the L-shaped rod 21 is located above the bucket truck 6, the L-shaped rod 21 is arranged along the left-right direction, and the rear end surface of the L-shaped rod 21 extends downward to form a mounting plate 22.

[0041] like Figure 1-Figure 3As shown, the locking assembly 3 includes a push rod 31, a locking block 32 and an elastic member 1 (not shown in the figure). The upper end of the push rod 31 is hingedly mounted on the front end surface of the mounting plate 22. An elastic member 1 is installed between the push rod 31 and the mounting plate 22. The elastic member 1 is a torsion spring. The two ends of the torsion spring are respectively connected to the push rod 31 and the mounting plate 22. The torsion spring is used to drive the push rod 31 to deflect upward in the counterclockwise direction to a horizontal state. The locking block 32 is installed in the L-shaped rod 21 to slide up and down. A groove matching the locking block 32 is provided at the upper end of the push rod 31. When the push rod 31 abuts against the outer side of the side wall where the handle of the bucket cart 6 is located, the locking block 32 is inserted in the groove to limit the rotation of the push rod 31. When the grain digger moves forward, the push rod 31 drives the bucket cart 6 to move forward together.

[0042] like Figure 1-Figure 4 As shown, the detection component 4 includes a plurality of sliders 41, a plurality of scrapers 42 and a driving unit. The plurality of sliders 41 are slidably mounted on the mounting plate 22 along the left-right direction. The driving unit is used to drive the sliders 41 to slide back and forth along the left-right direction, and the rear end surface of the slider 41 abuts against the front end surface of the mounting plate 22. The upper end of the scraper 42 is hinged on the front end surface of the slider 41. The rotation direction of the scraper 42 is parallel to the front-back direction. An elastic member 3 (not shown in the figure) is arranged between the scraper 42 and the slider 41. The two ends of the elastic member 3 are respectively connected to the scraper 42 and the slider 41. The elastic member 3 is used to drive the scraper 42 to remain vertical. The lower side of the scraper 42 is located in the upper opening of the bucket cart 6. A scraper rod 49 extending in the backward direction is installed near the lower end of the rear end surface of the scraper 42 for scraping the material in the bucket cart 6 to make the distribution of the material in the bucket cart 6 more uniform. As the height of the material increases, the resistance of the scraper 42 to the material during the reciprocating movement gradually increases, and the scraper 42 gradually begins to deflect upward.

[0043] like Figure 1-Figure 6As shown, the driving unit includes a reciprocating screw 43, a gear 1 44, a gear 2 45, a rotating shaft 46, a transmission belt 47 and a motor 48. A support plate 24 is provided on the front end surface of the mounting plate 22 and is located on the left side of the push rod 31. The left end of the reciprocating screw 43 is rotatably mounted on the short rod at the left end of the L-shaped rod 21, and the right end of the reciprocating screw 43 is rotatably mounted on the support plate 24. The reciprocating screw 43 is provided with a plurality of reciprocating spiral grooves, and nuts (not shown in the figure) are installed in the plurality of reciprocating spiral grooves. The slider 41 is sleeved on the nut, and the slider 41 is fixedly connected to the nut. The gear 1 44 is fixedly mounted on the left end of the reciprocating screw 43, and the gear 2 45 is rotatably mounted on the mounting shaft, and the gear 2 45 is located between the L-shaped rod 21 and the feeding pipe 11. In the gap between the two gears, a gear ring meshing with the gear one 44 is arranged on the front end face of the gear two 45, the rotating shaft 46 is passed through the feeding pipe 11 of the grain picker, and the rotating shaft 46 is located at the upper right of the mounting shaft, the motor 48 is mounted on the grain picker body 1, the motor 48 is connected to the rotating shaft 46, the rotating shaft 46 and the gear two 45 are transmitted by the transmission belt 47, when the motor 48 is started, the rotating shaft 46 rotates to drive the gear two 45 to rotate through the annular chain, the rotation of the gear two 45 drives the gear one 44 to rotate, the rotation of the gear one 44 drives the reciprocating screw 43 to rotate, because the rear end face of the slider 41 abuts against the front end face of the mounting plate 22, therefore when the reciprocating screw 43 rotates, the slider 41 reciprocates along the left and right directions on the mounting plate 22.

[0044] like Figure 1-Figure 6 As shown, a ring chain for feeding and a feeding plate installed on the chain are arranged in the feeding pipe 11 of the grain picker, a sprocket engaged with the ring chain is installed in the part of the rotating shaft 46 located in the feeding pipe 11, and a pressure switch 25 is installed on the lower end surface of the L-shaped rod 21 at the right side of the push rod 31. The pressure switch 25 is used to control the start and stop of the motor 48. When the push rod 31 deflects to the right to be horizontal, the pressure switch 25 is pressed to turn off the motor 48, and the grain picker no longer feeds.

[0045] like Figure 1 , Figure 3 , Figure 4As shown, the unlocking assembly 5 includes an unlocking rod 51, a push rod 52 and an elastic member 53. The unlocking rod 51 is slidably installed on the front end surface of the mounting plate 22, and the unlocking rod 51 is located above the reciprocating screw 43. The elastic member 53 is located between the unlocking rod 51 and the lower end surface of the long rod of the L-shaped rod 21. The elastic member 53 is used to apply an elastic force to the unlocking rod 51 to move downward and reset. The push rod 52 is installed on the right side of the hinge shaft of the scraper 42, and the push rod 52 and the scraper 42 are perpendicular to each other. The lower end surface of the unlocking rod 51 is fixedly connected to the upper end surface of the locking block 32. When the scraper 42 is deflected to the right by an angle greater than 60 degrees, the push rod 52 pushes the unlocking rod 51 to move upward, thereby driving the locking block 32 to disengage from the slot. At this time, the push rod 31 is driven by the elastic member 1 to deflect to the right to a horizontal state, the connection between the grain scraper and the bucket cart 6 is disconnected, and the grain scraper stops.

[0046] like Figure 2-Figure 5 As shown, a baffle plate 13 is installed below the discharge port 12 of the grain scraper, and the baffle plate 13 abuts against the inclined surface of the bucket pusher 6 to improve the stability of the connection between the mounting base 2 and the bucket pusher 6.

[0047] like Figure 1 , Figure 6 As shown, two groups of traction devices are provided, which are respectively located on both sides of the discharging port 12 of the hoeing machine.

[0048] The specific working principle of the present invention is:

[0049] When it is necessary to collect and transport materials, first push the bucket cart 6 towards the grain scraper so that the inclined surface of the bucket cart 6 abuts against the baffle plate 13, and then push the push rod 31 to deflect downward so that the push rod 31 abuts against the side wall of the bucket cart 6. At the same time, the slot on the push rod 31 is aligned with the locking block 32, and the unlocking rod 51 moves downward under the push of the elastic member 53, thereby driving the locking block 32 to move downward and insert into the slot, completing the connection between the grain scraper and the bucket cart 6. When the grain scraper moves forward, the bucket cart 6 is driven forward together by the push rod 31. When the push rod 31 deflects downward, the pressure switch 25 pops up downward, and the motor 48 starts at this time. The discharge port 12 of the grain scraper starts to discharge materials into the bucket cart 6. At the same time, after the motor 48 is started, it will drive the rotating shaft 46 to rotate, and the rotation of the rotating shaft 46 drives the gear 2 45 to rotate through the ring chain. The gear 44 is driven to rotate, and the rotation of the gear 44 drives the reciprocating screw 43 to rotate. Since the rear end face of the slider 41 abuts against the front end face of the mounting plate 22, when the reciprocating screw 43 rotates, the slider 41 reciprocates in the left and right directions on the mounting plate 22. When the scraper 42 reciprocates, it will gradually scrape the material in the push bucket 6 flat, so that the distribution of the material in the push bucket 6 is more uniform. As the material height increases, when the scraper 42 is gradually subjected to increasing resistance from the material, the scraper 42 gradually begins to deflect upward. When the scraper 42 deflects to the right at an angle greater than 60 degrees, the push rod 52 pushes the unlocking rod 51 to move upward, thereby driving the locking block 32 to disengage from the slot. At this time, the push rod 31 is driven by the elastic member 1 to deflect to the right to a horizontal position, the connection between the grain scraper and the push bucket 6 is disconnected, and the grain scraper stops, and then the push bucket 6 is pushed away.

[0050] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
