Description

Technical Field

[0001] The present application relates to the technical field of animal husbandry silage reclaiming equipment, and in particular to a silage reclaiming vehicle and a bottom silage reclaiming method. Background Art

[0002] In animal husbandry, silage technology is a technology or method to compact and seal the harvested fresh grass to isolate the grass from the outside air, causing internal hypoxia, so that anaerobic fermentation can produce organic acids, thereby inhibiting the reproduction of bacteria and obtaining silage. Silage can reduce nutrient loss and facilitate animal digestion and absorption.

[0003] After being stored for a certain period of time, silage needs to be taken out for livestock to eat. At present, silage reclaimers are widely used to take out silage. When taking materials, the silage reclaimer is driven to the front of the silage pile, and the roller head with multiple blades on the reclaimer scrapes off the silage from top to bottom. After scraping a certain amount, it can fall on the conveyor belt of the reclaimer, and the other end of the conveyor belt is connected by a feeding car. When using the current reclaimer to scrape silage, the roller head as a whole moves in an arc with the fulcrum at the rear end of the car as the center of the circle, and cannot touch the ground, so it cannot scrape the silage on the ground in front. After the reclaimer scrapes silage from a position, the reclaimer cannot move forward freely because there is a lot of silage left on the ground as a roadblock. It is necessary to manually shovel the silage on the ground onto the conveyor belt. After manually removing the roadblock, the reclaimer can move forward again, which makes the current silage reclaimer The degree of automation and work efficiency are not high enough. Summary of the invention

[0004] In view of the fact that the silage loader currently used in animal husbandry cannot pick up silage on the ground, it is necessary to manually shovel the silage on the ground onto the conveyor belt, which makes the current silage loader's automation level and work efficiency not high enough, this application proposes the following solution.

[0005] In a first aspect, the present application proposes a silage reclaimer and adopts the following technical solution.

[0006] A silage reclaimer comprises a frame and a conveyor belt mounted on the frame. The silage reclaimer also comprises a shovel, two sets of first telescopic mechanisms, two sets of second telescopic mechanisms and two sets of third telescopic mechanisms. The shovel is initially located below the front end of the conveyor belt.

[0007] Each side of the frame is provided with a group of the first telescopic mechanism, a group of the second telescopic mechanism and a group of the third telescopic mechanism. Each side of the frame has a slide slot. Each of the first telescopic mechanisms includes a first telescope, a slider and a connecting rod.

[0008] On each side of the frame: the slider is embedded in the slide slot, one end of the connecting rod is connected to the slider, and the other end is rotatably connected to the front end of the shovel. The stator of the first telescopic mechanism is fixed to the frame, and the output shaft acts on the slider. The stator of the second telescopic mechanism is rotatably connected to the frame, and the output shaft is rotatably connected to the rear end of the shovel. The stator of the third telescopic mechanism is connected to the frame, and the output shaft is connected to the stator of the second telescopic mechanism.

[0009] The second telescopic mechanism can drive the rear end of the shovel to move in front of the front end of the conveyor belt, and the third telescopic mechanism can drive the second telescopic mechanism to rotate, so that the rear end of the shovel rotates to above the front end of the conveyor belt. During this process, the slider moves freely along the slide groove. The first telescopic device can drive the slider to move back and forth, so that the front end of the shovel flips forward or backward.

[0010] By adopting the above technical scheme, in the animal husbandry industry, grass and other feeds are stored in cellars and other places for fermentation to obtain silage. When feeding livestock, the silage needs to be taken out. At this time, the silage picker of this scheme can be driven to the front of the silage pile, and the feed from the upper part to the lower part of the feed pile is automatically picked up by the picker arm to the conveyor belt. However, the silage close to the ground cannot be picked up by the picker arm. At this time, the shovel and its driving assembly installed in this scheme can be used to pick up the silage close to the ground. Specifically, under the drive of the first, second and third telescopic mechanisms, the front end of the shovel installed on the silage picker is close to the ground and shovels the silage on the ground forward, and then moves the shovel to the top of the conveyor belt, and rotates the shovel so that the silage on the shovel falls on the conveyor belt, and is transmitted to the rear end receiving vehicle by the conveyor belt. The first, second and third telescopic mechanisms can also drive the shovel to return to the initial position below the front end of the conveyor belt for recycling. This solution improves the automation level and work efficiency of the silage reclaimer, and can automatically pick up silage on the ground and put it onto the conveyor belt.

[0011] A preferred solution of the silage reclaimer is that the front end of the shovel is a smooth arc convex downward.

[0012] By adopting the above technical solution, after the front end of the shovel contacts the ground, it can move forward smoothly. During the moving process, the shovel can fit the ground well to scoop up the silage on the ground.

[0013] A preferred solution of the silage reclaimer is that the first telescopic mechanism includes a sleeve, and the sleeve is fixed to the output shaft of the first telescopic mechanism. The sleeve has a sliding hole, and when the slider moves along the slide groove, the slider also moves in the sliding hole. The first telescopic mechanism can drive the sleeve to move, so that the sleeve drives the slider to move backward, so that the front end of the shovel flips backward, or the sleeve drives the slider to move forward, so that the front end of the shovel flips forward.

[0014] By adopting the above technical solution, the first telescopic mechanism uses the cover, which will not limit the free sliding of the slider following the shovel, and can push the slider forward or backward after the slider slides freely to fold or unfold the shovel.

[0015] A preferred solution of the silage loader is that before the second telescopic mechanism drives the rear end of the shovel to move to the front end of the conveyor belt, the slider does not touch the lowermost end of the chute, and the first telescopic device can drive the cover to press against the slider so that the front end of the shovel presses against the ground, and at the same time, the cover does not touch the shovel and the ground.

[0016] By adopting the above technical solution, the sleeve can apply force to push the shovel, so that the front end of the shovel is close to the ground, so as to scoop up the silage on the ground more completely.

[0017] A preferred solution of the silage reclaimer is that the sliding block includes a coaxial bottom cylinder and an upper round rod. The diameter of the bottom cylinder is larger than the diameter of the upper round rod. The bottom cylinder is embedded in the slide groove. The upper round rod passes through the slide groove and through the slide hole to connect the connecting rod.

[0018] By adopting the above technical solution, the sliding block can rotate freely in the sliding groove, thereby not hindering the movement of the shovel.

[0019] A preferred solution of the silage reclaimer is that the stator of the third telescopic mechanism is rotatably connected to the vehicle frame, and the output shaft thereof is rotatably connected to the stator of the second telescopic mechanism.

[0020] By adopting the above technical solution, the third telescopic mechanism can drive the second telescopic mechanism to rotate, so as to move the shovel connected to the end of the second telescopic mechanism to above the conveyor belt.

[0021] A preferred solution of the silage reclaimer is that the silage reclaimer further includes a reclaiming arm and a fourth telescopic mechanism.

[0022] The material taking arm is located above the conveyor belt. The material taking arm comprises an arm body, a motor, a transmission chain and a roller cutter head. The rear end of the arm body is rotatably connected to the frame. The motor is fixed to the arm body. Both ends of the roller cutter head are connected to the front end of the arm body through bearings. The motor is connected to the roller cutter head through the transmission chain.

[0023] The stator of the fourth telescopic mechanism is rotatably connected to the frame, and the output shaft thereof is rotatably connected to the arm body, so as to drive the arm body to rotate with the connection point between the arm body and the frame as the center of the circle.

[0024] By adopting the above technical solution, the fourth telescopic mechanism drives the picking arm to rotate, so that the roller cutter head moves to the silage pile, and the motor drives the roller cutter head to rotate, so that the silage is pulled off and falls onto the conveyor belt.

[0025] On the second aspect, the present application also proposes a method for taking bottom silage, and adopts the following technical solution.

[0026] A method for collecting silage at the bottom, using the above-mentioned silage collecting vehicle to collect silage. The shovel is initially located below the front end of the conveyor belt, and there is no obstruction above the front end of the conveyor belt. The method for collecting silage at the bottom includes: The second telescopic mechanism extends to drive the shovel to move obliquely downward, and after the front end of the shovel touches the ground, it rotates around the rear end of the shovel as the axis. The second telescopic mechanism continues to push the shovel obliquely downward, causing the shovel to move forward until the rear end of the shovel reaches in front of the front end of the conveyor belt. The first telescopic mechanism contracts, causing the front end of the shovel to rotate backward to scoop up silage and keep the silage on the shovel. The third telescopic mechanism extends, causing the second telescopic mechanism to rotate upward until the rear end of the shovel is located above and in front of the front end of the conveyor belt. The second telescopic mechanism contracts, causing the rear end of the shovel to be located above the front end of the conveyor belt. The first telescopic mechanism contracts, causing the front end of the shovel to rotate backward, causing the silage on the shovel to slide onto the conveyor belt.

[0027] By adopting the above technical solution, the first, second and third telescopic mechanisms can drive the shovel to scoop up the silage on the ground and put it onto the conveyor belt.

[0028] A preferred solution of the bottom silage taking method is that after the front end of the shovel touches the ground, the first telescopic mechanism is driven to advance the slider, so that the connecting rod presses the front end of the shovel close to the ground, and in the state where the front end of the shovel is close to the ground, the shovel continues to be pushed forward until the rear end of the shovel reaches the front end of the conveyor belt.

[0029] By adopting the above technical solution, the front end of the shovel is close to the ground, so the silage on the ground can be scooped up better.

[0030] In summary, the silage retrieval vehicle and the bottom silage retrieval method of the present application have the following beneficial effects: the silage retrieval vehicle of the present application is used in the animal husbandry industry to scoop up silage, and the silage retrieval vehicle of the present application is additionally provided with a shovel and multiple driving mechanisms. The shovel can scoop up silage on the ground that cannot be scraped by the roller head, and automatically place the scooped silage on the conveyor belt, thereby improving the automation degree of the retrieval vehicle.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the following embodiments, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] like Figure 1 and Figure 2 A silage reclaimer is used for picking up silage in animal husbandry. The silage reclaimer comprises a frame 1, a conveyor belt 2, a reclaiming arm 3, a shovel 4, two sets of first telescopic mechanisms 5, two sets of second telescopic mechanisms 6, two sets of third telescopic mechanisms 7 and two sets of fourth telescopic mechanisms 8.

[0038] The frame 1 is supported on the bottom surface by four wheels. The conveyor belt 2 is a circulating conveyor belt 2 with a low front end and a high rear end, and is installed on the frame 1.

[0039] The material taking arm 3 is located above the conveyor belt 2. The material taking arm 3 comprises an arm body 301, a motor 302, a transmission chain 303 and a roller cutter head 304.

[0040] like Figure 3 The frame 1 has support rods 101 located on both sides of the conveyor belt 2 and whose upper ends are higher than the conveyor belt 2. The rear end of the arm body 301 is rotatably connected to the upper end of the support rods 101. The motor 302 is installed on the arm body 301. Both ends of the roller cutter head 304 are installed at the front end of the arm body 301 through bearings. The motor 302 is connected to the roller cutter head 304 through a transmission chain 303, and can drive the roller cutter head to rotate so as to scrape off the silage when the roller cutter head 304 is aligned with the silage pile.

[0041] The fourth telescopic mechanism 8 is a hydraulic cylinder, including a stator and an output shaft, wherein the stator is a cylinder barrel and the output shaft is a piston rod. The lower end of the cylinder barrel of the fourth telescopic mechanism 8 is rotatably connected to the frame 1, and the upper end of the output shaft is rotatably connected to the inner position of the arm body 301. When the fourth telescopic mechanism 8 is started, its output shaft moves up and down, and can drive the arm body 301 to rotate with its rear end as the axis, so that the roller head 304 can be positioned, and the roller head 304 can be driven to move from top to bottom to scrape silage from the silage pile from top to bottom.

[0042] Since the roller cutter head 304 moves in a circular motion from top to bottom and does not touch the ground, it cannot scrape the silage on the ground, that is, it cannot scrape the silage on the ground in front of the reclaimer. Therefore, the present application adds a shovel 4, two sets of first telescopic mechanisms 5, two sets of second telescopic mechanisms 6 and two sets of third telescopic mechanisms 7.

[0043] In the initial state, the shovel 4 is stored below the front end of the conveyor belt 2, that is, in a top view, the shovel 4 is shielded by the conveyor belt 2. The front end of the shovel 4 is a smooth downward convex arc structure, which is conducive to moving in close contact with the ground and shoveling silage on the ground.

[0044] On each side of the vehicle frame 1 , a group of first telescopic mechanisms 5 , a group of second telescopic mechanisms 6 and a group of third telescopic mechanisms 7 are respectively arranged.

[0045] like Figure 3 , there is a strip chute 102 on each side of the position where the conveyor belt 2 is installed on the frame 1. The first telescopic mechanism 5 includes a first telescopic device 501, a sleeve 502, a slider 503 and a connecting rod 504. The first telescopic device 501 can be a hydraulic cylinder, including a stator and an output shaft, the stator is a cylinder barrel, and the output shaft is a piston rod. The cylinder barrel of the first telescopic device 501 is fixed to the side of the frame 1, and its output shaft is connected to the sleeve 502. The sleeve 502 is placed above the chute 102. Figure 2 The sleeve 502 is in the shape of a strip and has a strip-shaped sliding hole 5021. The sliding hole 5021 is parallel to the sliding groove 102 and can be of the same shape. The sliding groove 102 is an inverted T-shaped cavity. Figure 4 The slider 503 includes a coaxial bottom cylinder 5031 and an upper round rod 5032. The diameter of the bottom cylinder 5031 is larger than the diameter of the upper round rod 5032. The bottom cylinder 5031 is embedded in the slide groove 102 and cannot be separated from the slide groove 102 upward. The upper round rod 5032 passes through the slide groove 102 and passes through the slide hole 5021 to connect one end of the connecting rod 504. The other end of the connecting rod 504 is rotatably connected to a front corner of the shovel 4. The two connecting rods 504 on both sides of the frame 1 are rotatably connected to the two sides of the front end of the shovel 4.

[0046] The second telescopic mechanism 6 can be a hydraulic cylinder, including a stator and an output shaft, wherein the stator is a cylinder barrel and the output shaft is a piston rod. A rod is extended downward on both sides of the position where the conveyor belt 2 is installed on the frame 1, and the cylinder barrel of the second telescopic mechanism 6 is rotatably connected to the rod, and the piston rod of the second telescopic mechanism 6 is rotatably connected to the rear end of the shovel 4. The second telescopic mechanism 6 is located as a whole below the first telescopic mechanism 5. The two second telescopic mechanisms 6 on both sides are respectively connected to both sides of the rear end of the shovel 4.

[0047] It can be seen from the connection structure of the first telescopic mechanism 5, the second telescopic mechanism 6 and the shovel 4 that the shovel 4 can be rotated by driving the first telescopic mechanism 5 or the second telescopic mechanism 6, which is used to scoop up silage on the ground. Figure 2 In order to limit the shovel 4 from excessively rotating toward the rear end and hindering the connecting rod 504 from pulling the shovel 4 back and rotating forward, a boss 5022 can be provided on the side of the sleeve 502 facing away from the slide groove 102. In the initial state, the connecting rod 504 leans against the boss 5022 to prevent the connecting rod 504 from excessively rotating backward.

[0048] In order to better deliver the silage on the shovel 4 to the conveyor belt 2, the shovel 4 needs to be delivered to the top of the conveyor belt 2. One way is to rotate the second telescopic mechanism 6 so that the shovel 4 is turned to the top of the conveyor belt 2. Therefore, the present application provides a third telescopic mechanism 7. The third telescopic mechanism 7 can be a hydraulic cylinder, including a stator and an output shaft, the stator is a cylinder barrel, and the output shaft is a piston rod. The cylinder barrel of the third telescopic mechanism 7 is rotatably connected to the frame 1, and the piston rod is rotatably connected to the cylinder barrel of the second telescopic mechanism 6.

[0049] The method for picking up silage at the bottom of the silage pile using the silage reclaimer is as follows: lift the reclaiming arm 3 off the conveyor belt 2, aim the front end of the reclaimer at the silage on the ground, and position the shovel 4 in its initial state. Start the second telescopic mechanism 6 to push the shovel 4 to move obliquely downward, with the front end of the shovel 4 abutting the ground. The first telescopic mechanism 5 extends to push the sleeve 502 to move obliquely downward, and the sleeve 502 pushes the slider 503 downward, pushing the connecting rod 504 to press down the shovel 4, so that the front end of the shovel 4 is close to the ground. Then, the second telescopic mechanism 6 and the first telescopic mechanism 5 extend at the same time, so that the shovel 4 moves forward with the front end close to the ground, thereby scooping up the silage on the ground. When the rear end of the shovel 4 moves to the front end of the conveyor belt 2, the movement of the second telescopic mechanism 6 is stopped, and the output shaft of the first telescopic mechanism 5 is contracted, so that the front end of the shovel 4 is lifted up by a small angle. This angle can keep the silage on the shovel 4 and prevent the shovel 4 from slipping off the shovel 4. In the process of the shovel 4 rising later, the angle between the connecting rod 504 and the output shaft of the second telescopic mechanism 6 is too small to be conducive to the first telescopic mechanism 5 pulling up the front end of the shovel 4. Therefore, the front end of the shovel 4 is lifted up by a small angle in advance, and the angle can be 10~45°. After that, the third driving mechanism is started to extend, and it pushes the second telescopic mechanism 6 to rotate upward, so that the shovel 4 is rotated to the front and upper part of the front end of the conveyor belt 2. At this time, the second telescopic mechanism 6 is started to contract, and the shovel 4 is pulled back to the upper part of the front end of the conveyor belt 2. At this time, the first telescopic mechanism 5 is started, so that the shovel 4 rotates upward and backward at a larger angle, so that the silage on the shovel 4 falls on the conveyor belt 2, and the conveyor belt 2 transports the silage to the rear end and falls onto the material transport vehicle.

[0050] It should be noted that the rear end of the shovel 4 described above moves to the front end of the conveyor belt 2 , that is, in the vertical direction, the rear end of the shovel 4 is located in front of the front end of the conveyor belt 2 .

[0051] After the silage on the shovel 4 slides onto the conveyor belt 2, the shovel 4 is reset to its initial state. The reset process is as follows: the first telescopic mechanism 5 is extended to make the front end of the shovel 4 flip forward; the second telescopic mechanism 6 is extended to make the rear end of the shovel 4 move to the front of the conveyor belt 2; the third telescopic mechanism 7 is shortened to make the second telescopic mechanism 6 rotate downward, driving the shovel 4 to rotate downward to the front and lower part of the conveyor belt 2; the second telescopic mechanism 6 shortens its output shaft to store the shovel 4 below the front end of the conveyor belt 2.

[0052] The above steps complete the collection of silage at the bottom. The bottom can be near the ground, such as a small height space above the ground of a silage storage pit such as a cellar, which is also the bottom of the silage pile.

[0053] The above silage reclaimer is used in animal husbandry to scrape silage in the silage tank. The silage reclaimer can automatically scoop up silage on the ground that cannot be picked up by the reclaiming arm 3. The silage reclaimer is provided with the first, second, and third telescopic mechanisms 7 and the shovel 4, etc., to drive the shovel 4 to scoop up the silage close to the ground onto the conveyor belt 2. The shovel can also automatically return to its position without affecting the normal reclaiming action of the reclaiming arm 3 next time. The silage reclaimer makes up for the defect that the roller head 304 of the reclaiming arm 3 cannot scrape the silage at a short height on the ground, automatically completes the reclaiming of silage at the bottom of the pile, and also allows the reclaimer to move forward without hindrance, continuously completes the reclaiming action at multiple positions, improves the automation level and work efficiency of the reclaimer, and has broad application prospects.

[0054] Although the present application has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
