Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and relates to a strong-push and soft-pull stem-pulling roller device for poppy harvesting and a working method thereof. Background Art

[0002] In the process of poppy cultivation for many years, mechanized harvesting has not been realized. The biggest problem of poppy cultivation at present is that a high yield does not necessarily lead to a good harvest. The main reason is that it is difficult to find enough pickers in time for manual picking, and the high picking fees and security costs have caused the cost of poppy cultivation to rise. According to rough statistics, the cost of poppy harvesting is second only to the cost of fertilizer in the total cost of cultivation, about 280-300 yuan per mu.

[0003] In the field of poppy harvesting, those skilled in the art have been working hard to innovate. Chinese patent document CN109769465B discloses a small chain poppy harvester, which includes a harvesting bin, a harvesting platform, a transmission system, a feeding device and a wheeled chassis; the harvesting platform includes a reciprocating cutter installed at the front end of the bottom plate, a plurality of harvesting units arranged in parallel and a harvesting platform drive shaft; each harvesting unit includes two parts that are symmetrical on the left and right, and the left and right parts of the harvesting unit include a straw divider, a guide, a puller, a vertical support plate, a clamping chain, a disc knife and a clamping chain horizontal mounting plate; the feeding device includes a screw conveyor; the transmission system drives the screw conveyor, the harvesting platform and the reciprocating cutter. Although the above patent document can adapt to the growth characteristics of poppy, meet the requirements of poppy harvesting, save manpower and material resources, and improve labor production efficiency. However, the roller in its structure has rubber on the surface, which cannot achieve the effect of flexibly pulling the stems, and it is easy to break the poppy shells and leak the seeds. In addition, there is no spiral device, and the poppies are pushed forward by the support chain, which cannot achieve the purpose of retaining shorter straw on the poppy fruits.

[0004] According to the research of the prior art, poppy shell can be processed into medicine. The length of the straw from the poppy fruit to the bottom is about 1.5 cm, and it still has some medicinal value. However, the longer straw contains very few medicinal ingredients and has almost no extraction value. Poppy seeds can be used for edible oil processing and have high utilization and nutritional value. Therefore, when harvesting poppy, it is required that neither the shell nor the seeds should be damaged, so the mechanical harvesting is required to be high; when harvesting poppy fruits, the existing poppy harvesting equipment has different lengths of straws, which are seriously broken and leaked, and there are many impurities in the poppy shell; poppy seeds can be used for edible oil processing, and leaking will cause great economic losses; the lengths of the straws of the harvested poppy fruits are different, and the long straws must be processed manually before they can be used. Summary of the invention

[0005] The invention provides a strong-push and soft-pull stem-pulling roller device for poppy harvesting, which avoids the problems of seed breakage and leakage and large amount of impurities in poppy shells during harvesting according to the growth characteristics of poppy fruits, so as to improve the harvesting efficiency and save manpower and material resources.

[0006] At the same time, the present invention also provides a working method of the strong-push and soft-pull stem-pulling roller device for poppy harvesting.

[0009] The brush roller is evenly fixed with bristles along its periphery; the brush roller and the spiral roller are equipped with an introduction cone head at one end, and the head of the introduction cone head is connected to the lower side of the frame through a front support; the other ends of the brush roller and the spiral roller are connected to a variable speed reversing transmission box to make them rotate in relative directions; the cutting knife is connected to the variable speed reversing transmission box.

[0010] Furthermore, the cutting knife is a disc knife.

[0011] Furthermore, a spiral structure is arranged on the outer surface of the spiral roller along its axial direction; and a spiral structure is also arranged on the introduction cone head.

[0012] Furthermore, the introduction cone head is divided into a head part and a tail part, which are connected by a bearing.

[0013] Furthermore, the speed-changing and reversing transmission box is installed at the rear of the frame in the direction of movement, and is located at the lower side of the frame.

[0014] Furthermore, the front end of the adjustment plate is separated to both sides; and an oblong hole is opened on the adjustment plate.

[0015] Furthermore, the power input shaft of the speed-changing reversing transmission box is connected to a power output device of the agricultural implement.

[0016] Furthermore, a material box is connected and fixed to the rear end of the frame.

[0017] The working method of the above-mentioned strong push and soft pull stem pulling roller device for poppy harvesting is characterized in that it comprises the following steps:

[0018] Step 1: poppies to be harvested enter the introduction cone head under the driving force of the agricultural implement and the guiding action of the straw divider, and driven by the power of the speed change reversing transmission box, the brush roller and the spiral roller rotate towards each other, and drive the corresponding introduction cone heads to rotate towards each other; under the rotation action of the introduction cone head, the poppy straw is sent between the brush roller and the spiral roller, the spiral roller pushes the poppy straw to the rear side, and the brush roller pulls the poppy straw downward;

[0019] Step 2: When the poppy fruits with shorter stalks touch the adjusting plate, the brush roller keeps them in a pulled-down state, and the spiral roller continues to push them backwards; the poppy fruits with taller stalks continue to be pulled down and pushed backwards, and when the stalks reach the rear end of the adjusting plate, the poppy fruits have touched the adjusting plate, and as the spiral roller continues to push forward, the poppy fruits that have completed the pulling of the stems reach the cutting knife position, and the cutting knife rotates to cut off the poppy fruits.

[0020] Beneficial effects of the present invention:

[0021] (1) In the present invention, by providing the brush roller and the spiral roller, during the process of poppy harvesting, since the brush roller is not designed with a spiral structure, it only plays the role of pulling the poppy straw downwards.

[0030] Example 1

[0031] Referring to the attached drawings, a strong push and soft pull stem pulling roller device for poppy harvesting is characterized in that it comprises a frame 1, a brush roller 2, a spiral roller 3, an adjustment plate 4 and a cutting knife 5; the rear end of the frame 1 is connected and fixed with a material box;

[0032] The frame 1 is divided into two parts, which are like a grain divider; a brush roller 2 and a spiral roller 3 are respectively installed on the lower side of the frame 1, and an adjustment plate 4 is respectively installed on the upper side of the frame 1. The cutting knife 5 is installed at the rear of the frame 1 in the moving direction and is located between the frame 1 and the adjustment plate 4;

[0033] The brush roller 2 is evenly fixed with bristles along its periphery; the brush roller 2 and the spiral roller 3 are equipped with an introduction cone 6 at one end; the introduction cone 6 is divided into a head and a tail, which are connected by a bearing 6.1; the head of the introduction cone 6 is connected to the lower side of the frame 1 through a front support 7, so that the introduction cone 6 can rotate synchronously with the brush roller 2 and the spiral roller 3; the outer surface of the spiral roller 3 is provided with a spiral structure along its axial direction; and the introduction cone 6 is also provided with a spiral structure;

[0034] The other ends of the brush roller 2 and the spiral roller 3 are connected to the speed-changing reversing transmission box 8 so that they rotate in relative directions; the cutting knife 5 is connected to the speed-changing reversing transmission box 8; the cutting knife 5 is a disc knife; the speed-changing reversing transmission box 8 is installed behind the movement direction of the frame 1 and is located on the lower side of the frame 1; the power input shaft 9 of the speed-changing reversing transmission box 8 is connected to the power output device of the agricultural machinery.

[0035] The front end of the adjusting plate 4 is separated to both sides, and an oblong hole is provided on the adjusting plate 4 to adjust the distance between the two adjusting plates 4. After the gap is adjusted by installing bolts in the oblong holes, the bolts are tightened to fix the adjusting plates to complete the gap adjustment. The purpose of adjusting the gap is to adapt to poppy shells of different sizes and to prevent the poppy shells from falling into the stem pulling roller due to the large gap.

[0036] Example 2

[0037] See attached Figure 5 The working method of the above-mentioned strong push and soft pull stem pulling roller device for poppy harvesting is characterized in that it includes the following steps:.

[0038] Step 1: poppy to be harvested enters the introduction cone head 6 under the driving force of the agricultural implement and the guiding effect of the straw divider, and driven by the speed change reversing transmission box 8, the brush roller 2 and the spiral roller 3 rotate towards each other, and drive the corresponding introduction cone heads 6 to rotate towards each other; under the rotation of the introduction cone head 6, the poppy straw is sent between the brush roller 2 and the spiral roller 3, the spiral roller 3 pushes the poppy straw to the rear side, and the brush roller 2 pulls the poppy straw downward;

[0039] Step 2: The height of poppy shells varies due to their growth. When the crop reaches the middle position of the roller, the shorter poppy shells have already touched the adjusting plate 4. Because the brush roller 2 plays a role in pulling the straw downward, the brush hairs are soft and the pulling force is limited, and due to the obstruction of the adjusting plate 4, the shorter poppies will not go down anymore, and there will be no crushing, squeezing or seed leakage. When the poppy fruit with shorter straw touches the adjusting plate 4, the brush roller 2 keeps it in the pulled-down state, and the spiral roller 3 continues to push it backward. The poppy fruit with taller straw continues to be pulled down and pushed backward. When the straw reaches the rear end of the adjusting plate 4, the poppy fruit has already touched the adjusting plate 4. As the spiral roller 3 continues to push forward, the poppy that has completed the pulling of the stem reaches the position of the cutting knife 5, and the cutting knife 5 rotates to cut off the poppy fruit. The poppy shell and the straw are separated at an effective distance and enter the material box.
