Description

Technical Field

[0001] The invention relates to the technical field of peanut harvesting equipment, and in particular to a fruit picking roller for a peanut harvester and a peanut harvester. Background Art

[0002] Peanut harvester is a crop harvesting machine that completes the operations of picking, picking fruits, and weeding during the peanut harvesting process. It generally includes a fruit picking part, a fruit collecting part, a straw collecting part, and a conveying mechanism. When harvesting peanuts, it is usually undesirable for the peanut shells to be broken. Therefore, for the fruit picking part, the existing peanut harvester usually adopts a longitudinal axial flow drum, which has the advantages of strong fruit picking ability, high picking rate, compact structure, high harvesting efficiency, strong adaptability, and relatively low peanut fruit breakage rate.

[0003] The longitudinal axial flow drum structure in the prior art is shown in the peanut harvester fruit picking drum disclosed in the Chinese utility model patent with the authorization announcement number CN206821338U, which includes a drum shaft, a drum body is installed on the drum shaft, the drum body is cylindrical, spokes are welded at both ends of the drum body, the drum shaft is connected to the drum body by spokes, the front end of the drum body is an introduction cone, the outer edge of the introduction cone is welded with two symmetrically arranged spiral introduction blades, the drum body is circumferentially distributed with tooth nail seats, and the tooth nail seats are distributed with fruit picking teeth. When in use, the fruit picking drum is assembled in the fruit picking device of the peanut harvester, and the upper and lower parts are cylindrical concave plate screens. During the fruit picking operation, the fruit picking drum rotates, and the peanut vines enter the fruit picking device under the grabbing action of the introduction blades, and the peanuts are separated from the stems under the beating and rubbing action of the fruit picking teeth nails and the concave plate screen.

[0004] In the prior art, in order to improve the grabbing efficiency of the introduction blades, two or more introduction blades are usually set on the fruit picking drum. For peanut vines with dry stems, the introduction blades can cut off the stems in time, immediately send the cut stems into the corresponding fruit picking device, and grab the next peanut vine in time, which really improves the grabbing efficiency. However, for wet peanut vines, the stems are tough and not easy to be cut off. When the wet peanut vines are fed from the feeding port of the fruit picking drum, the stems are long and it takes a certain amount of time for the introduction blades to completely feed them into the fruit picking device. When there are many introduction blades, one wet peanut vine grabbed by one of the introduction blades during the rotation process does not completely enter the fruit picking device, and the adjacent introduction blade grabs another wet peanut vine, which easily causes the wet peanut vine to block the feeding port of the fruit picking drum. In addition, the introduction blades will inevitably hit the peanut fruit during the rotation process. When there are too many blades, there is a large peanut breakage rate. Summary of the invention

[0005] The purpose of the present invention is to provide a peanut harvester with a fruit picking roller to solve the technical problems that the existing fruit picking roller easily crushes the peanuts and the feeding port is easily blocked; the purpose of the present invention is also to provide a peanut harvester with a low peanut crushing rate and not prone to blockage during fruit picking.

[0006] To achieve the above object, the technical solution of the peanut harvester fruit picking roller of the present invention is:

[0007] Peanut harvester with fruit picking roller, including:

[0008] Cylinder;

[0009] The roller is installed on the cylinder and is used to drive the cylinder to rotate;

[0010] The spiral introduction blade is connected to the feeding end of the cylinder and rotates with the cylinder to grab the peanut vines;

[0011] The number of the spiral introduction blade is one;

[0012] The cylinder is provided with a counterweight block, which is used to maintain the dynamic balance of the cylinder;

[0013] The length and spiral angle of the spiral introduction blades are such that the distance transported after one rotation is not less than the length of the peanut vine;

[0014] The counterweight block and the inlet blade are symmetrically arranged on both radial sides of the cylinder;

[0015] The counterweight block is welded and fixed on the cylinder.

[0016] Beneficial effect: Based on the characteristics of peanut crops, the fruit picking roller for the peanut harvester of the present invention is only provided with one spiral introduction blade on the cylinder body, and a counterweight is provided to balance the spiral introduction blade, thereby maintaining the dynamic balance of the cylinder body as a whole. Compared with the fruit picking roller with two or more spiral introduction blades provided in the prior art, the number of times the spiral introduction blade strikes the peanuts is reduced per unit time, and the crushing rate of the peanuts is correspondingly reduced; in addition, at the same rotation speed, the fruit picking roller of the present invention increases the feeding interval of the peanut crop in disguised form, especially for the wet peanut seedlings. The feeding length of the wet peanut seedling stems per unit time will be lengthened, which is convenient for feeding. In this way, after a wet peanut seedling is After being caught by a single spiral introduction blade and completely fed into the corresponding fruit picking device, another wet peanut vine will be caught by the spiral introduction blade. Therefore, it is not easy to get blocked at the feeding port of the fruit picking drum, which not only improves the feeding efficiency, but also improves the fruit picking efficiency. It can be applied to wet and dry harvesting of peanut crops at the same time, and has better versatility. It ensures that the spiral introduction blade can completely feed the peanut vine into the corresponding fruit picking device after one rotation, avoiding blockage at the feeding port of the fruit picking drum. The counterweight block and the introduction blade are symmetrically arranged on both sides of the radial direction of the cylinder body, which is conducive to ensuring the dynamic balance of the cylinder body. The counterweight block is welded and fixed to the cylinder body. During the rotation of the cylinder body, it can avoid the counterweight block from falling off and affecting the dynamic balance of the cylinder body.

[0017] Furthermore, the barrel includes a conical barrel section and a cylindrical barrel section which are connected to each other, the outer diameter of the conical barrel section gradually increases along the conveying direction of the peanut vines, the spiral introduction blade is fixed on the conical barrel section, and the counterweight block is fixed on the cylindrical barrel section.

[0018] Beneficial effects: The cylinder body includes a conical cylinder section. Along the conveying direction of the peanut vines, the fruit picking gap is larger in the front and smaller in the rear. In this way, the amount of material initially entering the drum can be increased, that is, the fruit picking range is increased, and the picking rate of the fruit picking drum is improved; fixing the counterweight block on the cylindrical cylinder section also facilitates the installation of the counterweight block.

[0019] The technical solution of the peanut harvester of the present invention is:

[0020] A peanut harvester includes a fruit picking system, wherein the fruit picking system includes a fruit picking roller, and the fruit picking roller includes:

[0021] Cylinder;

[0022] The roller is installed on the cylinder and is used to drive the cylinder to rotate;

[0025] The cylinder is provided with a counterweight block, which is used to maintain the dynamic balance of the cylinder;

[0026] The length and spiral angle of the spiral introduction blades are such that the distance transported after one rotation is not less than the length of the peanut vine;

[0027] The counterweight block and the inlet blade are symmetrically arranged on both radial sides of the cylinder;

[0028] The counterweight block is welded and fixed on the cylinder.

[0029] Beneficial effect: Based on the characteristics of peanut crops, the peanut harvester of the present invention has only one spiral introduction blade on the cylinder of the fruit picking drum, and a counterweight is set to balance the spiral introduction blade, thereby maintaining the dynamic balance of the cylinder as a whole. Compared with the fruit picking drum with two or more spiral introduction blades in the prior art, the number of times the spiral introduction blade strikes the peanuts is reduced per unit time, and the crushing rate of the peanuts is correspondingly reduced; in addition, at the same rotation speed, the fruit picking drum of the present invention increases the feeding interval of the peanut crop in disguised form, especially for wet peanut vines. The feeding length of the wet peanut vine stems per unit time will be lengthened, which is convenient for feeding. After a wet peanut vine is hit by a single spiral introduction blade, the peanut vine can be crushed to a desired size. After the spiral introduction blade grabs and sends it to the corresponding fruit picking device, another wet peanut vine will be grabbed by the spiral introduction blade. Therefore, it is not easy to get blocked at the feeding port of the fruit picking drum, which not only improves the feeding efficiency, but also improves the fruit picking efficiency. It can be applied to wet and dry harvesting of peanut crops at the same time, making the peanut harvester more versatile, ensuring that the spiral introduction blade can completely send the peanut vine into the corresponding fruit picking device after one rotation, avoiding blockage at the feeding port of the fruit picking drum, arranging the counterweight block and the introduction blade symmetrically on both sides of the radial direction of the cylinder body is conducive to ensuring the dynamic balance of the cylinder body, and welding and fixing the counterweight block on the cylinder body can avoid the counterweight block from falling off and affecting the dynamic balance of the cylinder body during the rotation of the cylinder body.

In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0039] The features and performance of the present application are further described in detail below in conjunction with the embodiments.

[0040] Embodiment 1 of the peanut harvester fruit picking roller of the present invention:

[0041] like Figure 1As shown, the fruit picking roller for the peanut harvester in this embodiment is a longitudinal axial flow fruit picking roller, which includes a cylinder 1 and a roller 2. The roller 2 is installed on the cylinder 1 and is coaxial with the axis of the cylinder 1. When the roller 2 rotates, it drives the cylinder 1 to rotate.

[0042] In this embodiment, the barrel 1 includes a conical barrel section 7 and a cylindrical barrel section 8. The conical barrel section 7 is welded and fixed to the front end of the cylindrical barrel section 8 to form a feeding section. The outer diameter of the cylindrical barrel section 8 is equal at all places, and the outer diameter of the conical barrel section 7 gradually increases along the conveying direction of the peanut vines. The maximum outer diameter of the conical barrel section 7 is the same as the outer diameter of the cylindrical barrel section 8.

[0043] Only one spiral introduction blade 3 is welded and fixed on the outer circumference of the conical barrel section 7. When the spiral introduction blade 3 rotates, it grabs the peanut vine through its front side and sends the peanut vine into the corresponding fruit picking device through its back side. At the same time, the spiral introduction blade 3 also has a certain cutting ability when rotating, and can cut off the stems of the peanut vine. The conical barrel section 7 is set, and the fruit picking gap is larger at the front and smaller at the rear along the conveying direction of the peanut vine. In this way, the amount of material initially entering can be increased, that is, the fruit picking range is increased, and the picking rate of the fruit picking roller is improved.

[0044] In order to avoid affecting the dynamic balance of the cylinder body by using only one spiral introduction blade 3, a counterweight 4 is welded and fixed on the outer peripheral surface of the cylindrical barrel section 8, so that the counterweight 4 is equivalent to being a whole with the cylinder body 1, and the counterweight 4 will not be thrown out when the cylinder body 1 rotates. In this embodiment, one end of the counterweight 4 is correspondingly welded to the connection between the conical barrel section 7 and the cylindrical barrel section 8, and the cross-section of this end of the counterweight 4 is arc-shaped, matching the contour of the outer peripheral edge of the cylindrical barrel section 8, so that the overall structure of the fruit picking drum is compact. At the same time, the counterweight 4 does not occupy the space on the cylindrical barrel section 8 as much as possible. In order to better ensure the dynamic balance of the cylinder body, the counterweight 4 is set at a position symmetrical to the spiral introduction blade 3 in the radial direction of the cylinder body 1.

[0045] In this embodiment, the counterweight 4 is made of thick steel plate, which is easy to obtain and has reliable welding.

[0046] A plurality of tooth nail seats 5 are evenly arranged on the circumference of the cylindrical barrel section 8, and each tooth nail seat 5 extends along the axial direction of the cylindrical barrel section 8 and is away from the counterweight block 4. A plurality of tooth nails 6 are arranged on each tooth nail seat 5 at intervals along the axial direction of the cylindrical barrel section 8. The tooth nails 6 can be forged into a knife-like structure with an arc on the upper part, thereby reducing the contact area between the tooth nails 6 and the peanut fruit, reducing the rubbing of the peanut fruit by the tooth nails 6, and thereby reducing the crushing rate of the peanut fruit.

[0047] In actual use, the rotation speed of the roller 2 has a certain setting range. It cannot be too large, otherwise the peanut vines are difficult to feed, and it cannot be too small, otherwise the teeth 6 are difficult to knock down the peanuts.

[0048] The length and spiral angle of the spiral introduction blade 3 meet the requirement that the conveying distance after one rotation is not less than the length of the peanut vine. For example, if the length of a peanut vine is 500 mm, the conveying distance after one rotation of the spiral introduction blade 3 is 500 mm, or greater than 500 mm, to ensure that one peanut vine can be completely delivered to the corresponding fruit picking device before grabbing the next peanut vine.

[0049] When the fruit picking drum for the peanut harvester of the present invention is working, the spiral introduction blade 3 grabs the peanut vine and conveys it to the rear of the cylinder 1. Under the striking action of the tooth nails 6, the peanut fruit is separated from its stem, and the separated peanut fruit falls into a special conveying mechanism on the peanut harvester and is transported to a collection box for collection; the separated stem and other debris are discharged backward. Since the fruit picking drum for the peanut harvester of the present invention has only one spiral introduction blade, compared with the fruit picking drum with two or more spiral introduction blades in the prior art, the number of times the spiral introduction blade strikes the peanut fruit per unit time is reduced, and the crushing rate of the peanut fruit is correspondingly reduced. In addition, at the same rotation speed, the fruit picking roller of the present invention increases the feeding interval of the peanut crop in disguised form, especially for wet peanut vines. The feeding length of the wet peanut vine stems per unit time will be lengthened, which is convenient for feeding. In this way, after one wet peanut vine is grasped by a single spiral introduction blade and completely fed into the corresponding fruit picking device, another wet peanut vine will be grasped by the spiral introduction blade. Therefore, it is not easy to get blocked at the feeding port of the fruit picking roller, which not only improves the feeding efficiency, but also improves the fruit picking efficiency. It can be applied to wet and dry harvesting of peanut crops at the same time, and has better versatility.

[0050] Embodiment 2 of the fruit picking roller for the peanut harvester of the present invention:

[0051] The difference between this embodiment and the above-mentioned embodiment 1 is that, in this embodiment, the counterweight block and the inlet blade are respectively located on the radial sides of the cylinder, but are arranged asymmetrically. The position of the counterweight block is set within a certain range according to the needs of dynamic balancing of the cylinder, and the position is not unique. For example, it is set away from the connection between the conical cylinder section and the cylindrical cylinder section.

[0052] Embodiment 3 of the fruit picking roller for the peanut harvester of the present invention:

[0053] The difference between this embodiment and the above-mentioned embodiment 1 is that, in this embodiment, the counterweight block can be detachably connected to the cylinder body. For example, a threaded hole is provided on the cylinder wall of the cylinder body, and the counterweight block is fastened to the cylinder body by a threaded fastener. In this way, if a different cylinder body is replaced, the counterweight block on the discarded cylinder body can be removed for reuse.

[0054] Embodiment 4 of the fruit picking roller for the peanut harvester of the present invention:

[0055] The difference between this embodiment and the above-mentioned embodiment 1 is that, in this embodiment, the cylinder body includes two cylindrical sections with different outer diameters, wherein the outer diameter of the cylindrical section where the tooth pin seat is provided is larger than the outer diameter of the cylindrical section where the spiral introduction blade is provided.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. The patent protection scope of the present application shall be based on the claims. All equivalent structural changes made using the description and drawings of the present application shall be included in the protection scope of the present application.
