Description

Technical Field

[0001] The utility model relates to the field of agricultural harvesting machinery, in particular to a pushing and rotating bolting device. Background Art

[0002] There are three main varieties of garlic seedlings in the market: mainly for harvesting garlic heads, mainly for harvesting garlic stalks, and for harvesting both garlic heads and garlic stalks. The third type is mainly planted in my country. Therefore, my country is not only the world's largest producer of garlic heads, but also the world's largest producer of garlic stalks, and this design mainly deals with this variety of garlic. Garlic stalks are the flower stems of garlic, which have high nutritional and health value and are an important source of income for garlic farmers. Therefore, the picking of garlic stalks is very important. Since the damage to garlic heads should be minimized as much as possible during the picking process of garlic stalks, the picking is difficult. At present, there are basically no mature research results on the mechanized harvesting technology of garlic stalks at home and abroad. Therefore, my country's garlic stalk picking is still in the stage of manual picking. Although some domestic scientific research institutions have developed a variety of garlic stalk picking devices, they have not been widely promoted and applied due to the high damage rate of garlic stalks, serious damage to garlic leaves, resulting in reduced garlic production, complex and high cost of the device, and low efficiency of garlic stalk picking. The flow operation of picking garlic stalks is mainly divided into three parts: cutting, bolting, and transportation and bundling. This structural design is used in the bolting process.

[0003] The research and development of garlic stalk harvesting machinery in my country is still in the theoretical research and development stage. At present, there are still many drawbacks in the design of the bolting part of the garlic stalk harvester.

[0004] In 2021, application number CN202110396464.9, Lu Fuyun and others applied for a garlic stalk picking machine, the applicant is Henan University of Science and Technology. The bolting device in this design uses a cam groove to control the position of the nylon pulley, thereby controlling the opening and closing of the mechanical clamp, closing and clamping the garlic stalk in front of the drum, and maintaining this state for a distance to pull out the garlic stalk, and then opening the Panasonic garlic stalk behind the drum. The garlic stalk falls into the stalk collection box due to its own gravity for collection. When working, the device can only bolt three rows of garlic stalks, and the picking efficiency is low, which does not meet the needs of agricultural production. And the spacing of the clamped garlic stalks is controlled by the cam groove and the pulley, so that the clamping spacing is not adjustable during the operation process, and the adaptability is poor. And whether the entire mechanism can accurately clamp the garlic sprouts requires that the garlic stalks are planted more standardized and the process requirements of the picking machine are higher.

[0005] CN109258091A discloses a novel electrically-driven garlic stalk harvester, wherein two stalk clips are tightened by cam control. During operation, the tightening interval is still fixed, and the adaptability is poor. Utility Model Content

[0006] The purpose of the utility model is to provide a push-rotating bolting device, which effectively solves the problems of the clamping arms of the bolting part in the background technology having a fixed spacing and poor adaptability during the working process. The clamping arms of the present application are not only highly adaptable during the clamping process, but also the clamping arms of the present application in a horizontal row are designed as an integrated unit, which is more conducive to the high-density design of the clamping arms, thereby improving the fault tolerance rate and success rate of bolting.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a push-rotating bolting device, characterized in that it comprises a drum rotating shaft, a supporting disk is sleeved on the drum rotating shaft, and also comprises a movable disk sleeved on the drum rotating shaft and arranged at intervals from the supporting disk, and a plurality of groups of clamping structures are arranged at intervals between the supporting disk and the movable disk;

[0008] A fixed protrusion disk is rotatably connected to the drum rotating shaft on the axially outer side of the movable disc, and an end face cam structure is arranged on the side of the fixed protrusion disk facing the movable disc;

[0009] The clamping structure includes a fixed support rod with two ends respectively fixed on the support plate and the movable disc, and a movable support rod matched with the fixed support rod, one end of the movable support rod close to the support plate is connected with a spring, the other end of the movable support rod passes through the movable disc and can slide axially on the movable disc, the movable support rod can be displaced axially along the rotating shaft of the drum, a plurality of fixed clamps are axially fixed on the fixed support rod, a plurality of movable clamps are axially arranged on the movable support rod, and the fixed clamps and the movable clamps cooperate one by one to tighten and loosen the garlic scapes;

[0010] One end of the movable support rod extending out of the movable disc is rotatably connected to a roller, and the roller cooperates with the end face cam structure, so that when the roller is lifted by the end face cam, the elastic force of the spring can be overcome to move the movable clamp away from the fixed clamp. After the lifting section of the end face cam ends, the movable clamp approaches the fixed clamp under the elastic force of the spring to clamp the garlic sprout.

[0011] Preferably, the movable disc is fixed on the rotating shaft of the drum, and a plurality of sliding holes cooperating with the movable support rods are opened on the movable disc, and the movable support rods are slidably fitted in the sliding holes.

[0012] Preferably, the end face cam structure is composed of a raised segment and a platform segment extending in a circular arc and arranged on a fixed raised disk, wherein the raised segment and the platform segment are connected end to end to form a circle, and the roller is lifted up at the raised segment and the lifting ends at the platform segment.

[0013] Preferably, there is an oblique angle transition or an arc transition between the raised section and the platform section.

[0014] Preferably, the fixed support rod is provided with a slide groove, the bottom of the movable support rod is provided with a slide rail slidably connected in the slide groove, and the connection between the fixed clamp and the fixed support rod is provided with a notch for the movable support rod to slide through. As an embodiment, the notch is open toward one side of the moving direction or the opposite direction of the fixed support rod.

[0015] Preferably, the relative clamping surfaces of the movable clamp and the fixed clamp are both wavy, and the crests and troughs of the wavy patterns of the movable clamp and the fixed clamp are interlocked. The raised or recessed parts of the wavy patterns extend toward the movement direction of the support rod.

[0016] Preferably, the minimum dimension of the distance between the relative clamping surfaces of the movable clamp and the fixed clamp is 3 mm, and the maximum dimension is 7 mm.

[0017] Preferably, the movable clamp and the fixed clamp are both made of hard rubber material, or the movable clamp and the fixed clamp are made of metal material, and an elastic rubber layer is fixed on the opposite clamping surfaces.

[0018] Preferably, the movable clamp and the fixed clamp matched therewith constitute a clamping unit, and the clamping units of two adjacent rows are arranged alternately. Multiple clamping units in the same row are in contact with each other in sequence, that is, when the movable support rod is lifted by the end cam, the movable clamp and the fixed clamp of another adjacent clamping unit are in back-to-back contact. This arrangement allows the clamping units of the entire row to be connected one after another, thereby improving the bolting efficiency.

[0019] Preferably, a boss is provided on the fixed support rod on one side of the spring, one end of the spring is connected to the movable support rod, and the other end of the spring is connected to the boss.

[0020] The beneficial effects of the utility model are:

[0021] 1. High bolting efficiency: Each bolting unit is composed of multiple clamping units. The clamping units are small in size, large in number, and adopt a side-by-side design. They can bolt garlic seedlings with a width of about 1.25 meters (the width can be changed according to demand) at the same time, greatly improving the bolting efficiency;

[0022] 2. High bolting success rate: The bolting units are connected by support plates and movable discs at both ends to form a drum-type structure. During the clamping process, each plant has a probability of being clamped by multiple clamping units (the corresponding movable clamps and fixed clamps constitute a clamping unit) to achieve bolting (if the garlic stalk is not effectively clamped by the bolting unit, the next bolting unit can still clamp the garlic seedling), which improves the fault tolerance of the bolting process and greatly improves the bolting success rate;

[0023] 3. Strong stability: The device adopts a purely mechanical structure design with high stability and reliability. It does not use electronic components or sensors, thus reducing the risk of downtime or performance degradation due to electronic failure. Its structure is simple and direct, making the agricultural machinery more stable and reliable during operation and able to adapt to various complex farmland environments and climatic conditions.

[0024] 4. Less destructive to garlic stalks: Considering that garlic stalks may have obvious regional differences in diameter due to factors such as terrain, sunlight, and uneven regional distribution of water, we designed a compression spring device on the left side of the bolting unit. After the raised section on the fixed raised disk ends, the compression spring pushes the movable clamp to move to the right, and the mechanism enters the clamping stage. At this time, the distance between the movable clamp and the fixed clamp is determined by the diameter of the garlic stalk clamped by this bolting unit. The force for clamping the garlic stalk is provided by the spring. This design solves the problem of being unable to clamp or severe clamping and squeezing damage due to differences in diameter of garlic stalks in different regions or varieties. While minimizing the damage to the garlic stalks, it greatly improves the bolting rate. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0041] The following will be combined with the attached embodiment of the present utility model Figure 1-13 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] The utility model designs a push-rotating bolting device, which is used in the bolting part of a garlic stalk harvester. A garlic stalk cutting mechanism or a garlic stalk splitting mechanism is arranged in front of the device. Since there are many existing technologies for the front mechanism, and the technical problem solved by the utility model is the bolting stage, the cutting or splitting mechanism in front of the bolting is not described here.

[0043] The push-rotating bolting device is composed of a bolting unit, a fixed protruding disk 4, a supporting disk 2, a movable disc 3 and a bolting drum shaft. The bolting unit is composed of a movable clamp 9, a fixed clamp 8, a compression spring 7 and a nylon roller 10. Figure 3 As shown, twenty circular arrays of bolting units and the movable discs 3 at both ends together form a drum structure as shown in FIG. Figure 4 shown.

[0044] When the utility model is installed, it is installed at the rear of the cutting or stem splitting mechanism 19 of the garlic stalk harvester, and the drum rotating shaft 1 is rotatably connected to the frame 20, and the drum rotating shaft 1 is driven to rotate by the power mechanism, and the fixed protrusion plate 4 is fixed on the frame. A receiving mechanism for receiving garlic stalks is arranged at the rear of the garlic stalk harvester. The fixed support rod 5, the movable support rod 6, the fixed clamp 8, the movable clamp 9, the spring 7 and the roller 10 of each row constitute a group of clamping structures, and the clamping structures are arranged circumferentially on the support plate 2 and the movable disc 3 to jointly constitute a bolting drum structure. The drum structure of the utility model is provided with a frame bottom plate 22 at the bottom of one side facing away from the walking direction, and the end of the frame bottom plate 22 extends forward between the end of the drum structure facing away from the walking direction and the bottom end of the drum structure, which is convenient for receiving materials and prevents the garlic seedlings from entering between the drum and the frame bottom plate.

[0045] The rotary shaft 1 of the drum of the utility model rotates with the support plate 2 and the movable plate, thereby driving the multiple groups of clamping structures to rotate, while the fixed protrusion plate 4 does not rotate, so that the rollers 10 on each row of the clamping structures make a circular motion on the fixed protrusion plate 4. The rollers 10 alternately switch between the platform section 13 and the protrusion section 12, so that the movable clamp 9 alternately approaches and moves away from the fixed clamp 8, completing the clamping and releasing actions.

[0046] A plurality of transparent sliding holes 11 are opened on the movable disk, so that the movable support rod 6 can slide through the sliding hole 11 and pass through the end portion to be rotatably connected to the roller 10 that cooperates with the end face cam structure.

[0047] There is an angled transition or an arc transition between the raised section 12 and the platform section 13. This makes the nylon roller 10 more stable when switching between the platform section 13 and the raised section 12. Of course, as another embodiment, the raised section 12 can be replaced by a recessed section, while the platform section 13 remains unchanged. The platform section 13 is the end surface portion of the fixed raised disc 4 itself. This embodiment constitutes a jacking at the platform section 13 and a non-jacking at the recessed section. Jacking and non-jacking are only relative. For the fixed raised disc 4, the jacking portion bulges outward relative to the non-jacking portion.

[0048] As an embodiment, two sections of slide grooves 14 are provided on the fixed support rod 5, and a notch 15 connected to the fixed support rod 5 is provided on the fixed clamp 8. The notch 15 is open to one side in the direction of movement of the fixed rod or in the opposite direction, so that the movable support rod 6 can be inserted into the notch 15. Two slide rails 18 slidably connected in the slide grooves 14 are provided at the lower end of the movable support rod 6, so that the movable support rod 6 can slide relative to the fixed support rod 5. When the movable clamp 9 is provided, the end of the movable clamp 9 facing away from the notch 15 is extended to form an extension part 21, and the end face of the extension part in the extension direction is flush with the corresponding end face of the fixed clamp 8, so that the clamping size of the fixed clamp 8 and the movable clamp 9 is consistent. The row of integral sliding movable clamps 9 of the utility model allows the size of the utility model to be designed to be smaller, and the row of movable clamps 9 only needs to share a set of driving mechanisms, namely the end face cam and roller 10. In order to further improve the compactness of the utility model, when the movable clamp 9 is lifted up by the raised section 12, the back side of the movable clamp 9 opposite to the clamping surface can contact another fixed clamp 8 in contact with it.

[0049] As an embodiment, the movable clamp 9 and the fixed clamp 8 can be made of metal materials, such as iron or stainless steel. In order to improve the elasticity of the movable clamp 9, the movable clamp 9 and the fixed clamp 8 can also be made of hard rubber material, or a metal material is used as a basis, and an elastic rubber layer is laminated on the clamping surface of the movable clamp 9 and the fixed clamp 8 made of metal material. This can better protect the garlic scapes from being damaged by clamping, and the friction is friendly.

[0050] As an embodiment, the clamping units composed of two adjacent rows of movable clamps 9 and fixed clamps 8 can be arranged in an interlaced manner, and the clamping units in multiple rows can also be mutually staggered as required. In this way, when the current clamping unit cannot clamp the garlic scape, the clamping units in the next rows that are mutually staggered can be used as supplements, thereby improving the clamping accuracy.

[0051] As an embodiment, one end of the spring 7 is fixedly connected to the movable support rod 6, and the other end of the spring 7 is also fixedly arranged. The fixed arrangement is: the other end of the spring 7 can be connected to the support plate 2, and can also be connected to the boss 17 arranged on the fixed support rod 5. Most preferably, a telescopic rod with two ends respectively connected to the movable support rod and the boss can be arranged in the spring, and the purpose of using the telescopic rod is to maintain the axial stability of the spring.

[0052] As an embodiment, the fixed protrusion disk 4 can be rotatably mounted on the drum drive shaft, or can be spaced on the drum drive shaft. However, the fixed protrusion disk 4 must be fixed on the frame to ensure that the drum drive shaft can rotate relative to the fixed protrusion disk 4.

[0053] After the machine is started, while the machine body moves forward, the bolting drum rotating shaft 1 continuously drives the bolting drum to rotate at a speed of 6r / min. Before the bolting unit reaches the effective bolting position (the point where the raised section 12 on the fixed raised disk 4 transitions to the platform section 13), the nylon roller 10 on the right side of the movable clamp 9 is located at the raised section 12 of the fixed raised disk 4, and the movable clamp 9 is in a jacking state. At this time, the maximum distance between the movable clamp 9 and the fixed clamp 8 is 7mm. When the bolting unit rotates to the effective bolting point, the bolting unit and the garlic seedling plant produce relative movement, so that the garlic stems enter the clamping unit smoothly. At this time, the raised section 12 on the fixed raised disk ends, and the nylon roller 10 on the right side of the bolting unit runs to the platform section 13 of the fixed raised disk. 17 disappears, and the movable clamp 9 in the bolting unit moves to the left due to the horizontal leftward force given by the left compression spring 7, and the size of the clamping unit becomes smaller, so that the garlic stalk is squeezed by the movable clamp 9 and the fixed clamp 8, thereby achieving the effect of clamping the garlic stalk; after the garlic stalk is clamped, the bolting unit continues to make a circular motion, and the friction force generated by squeezing the garlic stalk makes the garlic stalk move in a circular motion, thereby causing the garlic stalk to be pulled out of the garlic seedling, and the drum drives the garlic stalk to rotate 230°, and the nylon roller 10 on the movable clamp 9 reaches the raised section 12 on the fixed raised disk 4, and the movable clamp 9 is lifted up by the boss 17 on the fixed raised disk 4 and moves to the left, so that the distance between the movable clamp 9 and the fixed clamp 8 becomes larger, and the garlic stalk falls onto the conveyor belt of the conveying device of the structural mechanism, and the bolting process ends.

[0054] Advantages of this utility model:

[0055] 1. Push-type garlic stalk clamping method design: A compression spring 7 device is used on the left side of the bolting unit. In the bolting unit, the fixed clamp 8 is connected to the movable disc 3, the left end of the movable clamp 9 is in contact with the compression spring 7, and the nylon wheel on the right end cooperates with the fixed protrusion disc 4, which can realize the horizontal movement of the movable clamp 9, thereby changing the distance between the movable clamp 9 and the fixed clamp 8 to realize the function of clamping the garlic stalk. When clamping the garlic stalk, the distance between the movable clamp 9 and the fixed clamp 8 is determined by the diameter of the clamped garlic stalk (because the spring 7 drives the movable clamp 9 to clamp close to the fixed clamp 8 and has a certain elasticity), and the force of clamping the garlic stalk is controlled by the compression spring 7 (which can be adjusted according to different situations), avoiding the problem that the garlic stalk cannot be clamped or is severely damaged due to regional differences in diameter.

[0056] 2. Unique design of two clamps: The movable clamp 9 and the fixed clamp 8 adopt a wave pattern 16 structure (increasing the contact area with the garlic stalk). This design greatly increases the pressure on the garlic stalk when clamping to ensure the successful clamping action.

[0057] 3. Clamping distance design: Since the bolting device has no recognition function, we compensate for the randomness problem in the bolting process by reducing the size of the clamping unit. Considering that garlic leaves may be accidentally clamped during the bolting process, we set the minimum size of the clamping unit (the size of the clamping unit when the nylon roller 10 on the movable clamp 9 in the bolting unit is on the platform section 13 of the fixed raised disk 4) to 3mm, and the longitudinal size (thickness) of the garlic leaf is about 1-2mm, which is smaller than the minimum clamping unit size, and the transverse size of the garlic leaf is larger than the maximum clamping unit size (7mm), avoiding the problem of garlic seedling leaves being clamped and damaged. The switching of the state of the minimum distance and the maximum distance between the movable clamp and the fixed clamp of the utility model (for example, it can be 3mm and 7mm, with the minimum distance being larger than the longitudinal thickness of the garlic leaf and smaller than the diameter of the garlic stalk, and the maximum distance being smaller than the transverse dimension of the garlic leaf) can be achieved by the end face cam structure, that is, the height difference between the convex section and the platform section of the end face cam structure is the difference between the maximum distance and the minimum distance (for example, 4mm), when the roller is in the convex section, the distance between the movable clamp and the fixed clamp is the maximum distance (for example, 7mm), and when the roller is in the platform section, the two clamps are close to each other under the maximum use of the spring, but due to the obstruction of the platform section, the two are close to each other until they are at the minimum distance.

[0058] 4. Bolting unit design: In order to improve the efficiency of picking garlic stalks, the bolting unit is designed. Each row of bolting units consists of 53 clamping units, which can harvest garlic seedlings 1.25 meters wide (about 10 ridges) at the same time. While ensuring the quality of bolting, it saves manpower and greatly improves the efficiency of garlic stalk harvesting.

[0059] 5. Drum design: The bolting units are connected by movable discs 3 at both ends to form a drum structure. During the clamping process, each plant has a probability of being clamped by multiple clamping units to achieve bolting (if the garlic stalk is not effectively clamped by the bolting unit, the next bolting unit can still clamp the garlic seedling), which improves the fault tolerance of the bolting process and greatly improves the success rate of bolting.
