Description

Technical Field

[0001] The invention relates to the technical field of feed sampling and detection, and in particular to a hay sampling device. Background Art

[0002] At present, the production technology of hay bales in animal husbandry is becoming more and more mature and large-scale, so the correct sampling of hay and the assessment of its nutritional value are extremely important. However, there are only grain and concentrate samplers on the market, and their production and processing technology is mature, and the production of roughage samplers, especially hay samplers, is almost blank. Most of the hay sampling can only be done manually, which is time-consuming and labor-intensive, destroys the structure of the bale, and the samples are not representative. In addition, due to the high density of hay bales, common manual hay samplers generally require a lot of effort to complete the sampling, which is extremely difficult for female samplers with less strength to sample; there are also electric and imported hay samplers on the market, but they all have the problem of slow sampling speed; or small sampling volume, and repeated sampling is required to reach the required test sample weight; or they are directly retained in the sampling tube / sampler after sampling, and cannot be quickly packaged, affecting the moisture test results; or partially retained in the sampling tube / sampler, and the sample is easily leaked when transferred from the sampling tube / sampler to the storage bag, resulting in incomplete sample collection and affecting the test results.

[0003] Chinese patent CN202547972U discloses a new type of electric hay sampler, which greatly speeds up the sampling process and reduces human factors. However, due to the small diameter of the sampling tube of the sampler, the hay sample is often difficult to unload after the hay is sampled, and if you are not careful, it is easy to cause the hay sample to leak, resulting in incomplete sampling and collection, affecting the detection results; in addition, during the sampling process of the hay sampler with this structure, the internal space of the sampling tube is limited, and the hay is often held in the air. After entering the sampling tube, it is easy to be compacted, and the longer the electric drill works, the more hay enters the sampling tube, the more compacted the hay is, and further sampling will be more difficult. When it reaches a certain level, the hay in the sampling tube will be stuck in the sampling tube, causing the hay outside to no longer enter the sampling tube, causing the sampling tube to no longer rotate, and the sampling head end can no longer continue to cut the hay, but the electric drill is still rotating and working, which can easily lead to inconsistent motion states between the electric drill and the sampling tube, and the two are easily disengaged and separated, making it impossible to continue sampling. Summary of the invention

[0004] The invention aims to provide a hay sampling device, which has a fast sampling speed, a large single sampling volume, is easy to collect hay samples and is not easy to leak, and is simple and convenient to operate.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A hay sampling device comprises an electric drill and a sampling barrel, and also comprises a drill rod, wherein the drill rod is detachably arranged on the electric drill, and the electric drill can drive the drill rod to rotate; the drill rod comprises a tip portion, a shaft rod and a spiral conveying portion, wherein the tip portion is arranged at one end of the shaft rod, and the spiral conveying portion extends in a spiral shape along the axial direction of the shaft rod; the sampling barrel comprises a barrel body and a plurality of fixed pointed feet, wherein a first opening, a second opening and a discharge port are arranged on the barrel body, and a fixed pointed angle is arranged on the first opening side of the barrel body; the tip portion of the drill rod, the shaft rod and the spiral conveying portion can pass through the barrel body and the first opening through the second opening, and the second opening is connected to a guide sleeve, and the guide sleeve is arranged in the barrel body.

[0007] Preferably, the spiral conveying portion is widened longitudinally to form a cutting edge.

[0008] Preferably, the cylinder is connected to the discharge cylinder via a discharge port.

[0009] Preferably, the diameter of the second opening is slightly larger than that of the spiral conveying part, and a discharge hole is provided on the guide sleeve.

[0010] Preferably, a sleeve is provided on the electric drill, and a guide groove matching the size of the sleeve is provided on the barrel. When the drill rod tip, the shaft and the spiral conveying part pass through the barrel and the first opening from the second opening, the sleeve is inserted into the guide groove.

[0011] Preferably, the discharge barrel is detachably connected to the storage bag.

[0012] Preferably, a square head or a hexagonal head matching with an electric drill is provided on the drill rod.

[0013] Preferably, the fixed sharp angle axial array is arranged on the first opening side of the cylinder, and the ends of the fixed sharp angles are pointed.

[0014] Preferably, the angle between the cylinder and the discharge cylinder is 70° to 80°.

[0015] Further preferably, a guide shaft is provided on the electric drill, and a guide shaft groove matching the size of the guide shaft is provided on the barrel, and when the drill rod tip, the shaft rod and the spiral conveying part pass through the barrel and the first opening from the second opening, the guide shaft is inserted into the guide shaft groove.

[0016] In the above technical scheme, the sampling barrel is quickly and stably fixed on the hay bale by inserting the fixed sharp corner of the axial array set on the first opening side of the barrel into the high-density hay bale; the tip of the drill rod, the shaft rod and the spiral conveying part pass through the barrel and the first opening from the second opening, and the electric drill drives the drill rod to rotate and then drives the tip, the shaft rod and the spiral conveying part to rotate, the tip cuts the hay bale and moves into the inside of the hay bale, and the cut hay sample forms a continuous accumulation of hay samples through the pitch of the spiral conveying part, until the hay sample is pushed into the barrel and falls into the discharge barrel from the discharge port, and then is collected by the discharge barrel into the storage bag, thereby realizing the sampling, collection and storage of hay. The setting of the discharge port prevents the hay samples in the cylinder from being packed at a high density or compacted. The coordinated setting of the guide sleeve and the spiral conveying part can not only prevent the hay samples from being transported to the outside of the cylinder with the spiral conveying part, causing leakage and incomplete collection of the hay samples, but also can further guide the movement of the spiral conveying part, prevent the spiral conveying part from being stuck on the second opening, and further improve the convenience of operation. By widening the spiral conveying part longitudinally to form a cutting blade, the spiral conveying part also has a certain cutting function, further improving the sampling speed and greatly improving the service life of the drill rod.

[0021] The present invention will be further described below in conjunction with the accompanying drawings:

[0022] like Figures 1 to 4As shown, the hay sampling device comprises an electric drill 1, a sampling barrel 2 and a drill rod 3, wherein the drill rod 3 is detachably connected to the electric drill 1 by setting a square head or a hexagonal head matched with the electric drill 1 at the head of the drill rod 3, and the drill rod 3 is driven to rotate by the electric drill 1; the drill rod 3 comprises a tip portion 31, a shaft rod 32 and a spiral conveying portion 33, the tip portion 31 is arranged at one end of the shaft rod 32, the spiral conveying portion 33 is spirally extended along the axial direction of the shaft rod 32, the sampling barrel 2 comprises a barrel body 21 and three to six fixed pointed feet 22, a first opening 23, a second opening 24 and a discharge port 25 are provided on the barrel body 21, the fixed pointed corners 22 are axially arranged in an array on the side of the first opening 23 of the barrel body 21, and the ends of the fixed pointed corners 22 are pointed, so that they can be quickly and firmly inserted into the hay bale; the second opening 24 is connected to a guide sleeve 26, and the guide sleeve 26 is arranged in the barrel body 21. In this embodiment, the spiral conveying part 33 is widened longitudinally to form a cutting blade 34, and the cylinder 21 is connected to the discharge barrel 4 through the discharge port 25. The setting of the discharge barrel 4 allows the storage bag to be conveniently and detachably set on the discharge barrel 4, so that the hay sample can be collected while sampling. First, use the fixed sharp corner 22 to quickly and firmly insert it into the hay bale, then insert the tip 31, shaft 32 and spiral conveying part 33 of the drill rod 3 through the second opening 24 into the cylinder 21 and the first opening 23, turn on the electric drill 1, the electric drill 1 drives the drill rod 3 to rotate and then drives the tip 31, shaft 32 and spiral conveying part 33 to rotate, the tip 31 begins to cut the hay bale and move into the inside of the hay bale, and the cut hay sample is formed into a continuous accumulation of hay samples through the pitch of the spiral conveying part 33, until the hay sample is pushed into the cylinder 21 and falls into the discharge barrel 4 through the discharge port 25, and then is collected into the storage bag by the discharge barrel 4, thereby realizing the collection and storage of hay samples during the collection and sampling process, without taking out the drill rod 3 from the cylinder 21 and then transferring the hay sample to the storage bag separately, and the operation is more convenient. The setting of the discharge port 25 prevents the hay sample in the cylinder 21 from having a high stacking density and being compacted, and the single sampling volume is large. The diameter of the second opening 24 is set to be slightly larger than the spiral conveying part 33, and a discharge hole 27 is added to the guide sleeve 26. The size matching setting of the guide sleeve 26 and the spiral conveying part 33 can not only prevent the hay sample from being transported to the outside of the cylinder 21 with the spiral conveying part 33, causing the hay sample to be leaked and incompletely collected, but also further guide the movement of the spiral conveying part 33, preventing the spiral conveying part 33 from being stuck on the second opening 24, and further improving the convenience of operation; the setting of the discharge hole 27 further prevents the hay sample from being discharged from the gap between the guide sleeve 26 and the spiral conveying part 33 to the outside of the cylinder 21, causing the hay sample to be leaked. By widening the spiral conveying part 33 longitudinally to form a cutting blade 34, the spiral conveying part 33 also has a certain cutting function, further improving the sampling speed and greatly improving the service life of the drill rod 3.After the hay samples are collected, the drill rod 3 is directly pulled out from the first opening 23, the cylinder 21 and the second opening 24, and then the fixed sharp corner 22 is pulled off from the hay bale to sample the next sampling point.

[0023] In a preferred embodiment, a sleeve 5 is provided on the electric drill 1, and a guide groove 51 matching the size of the sleeve 5 is provided on the barrel 21, so that when the tip 31 of the drill rod 3, the shaft 32 and the spiral conveying part 33 pass through the barrel 21 and the first opening 23 from the second opening 24, the sleeve 5 is inserted into the guide groove 51, which further guides the movement of the drill rod 3 and further reduces the wear of the spiral conveying part 33. Alternatively, a guide shaft 6 is provided on the electric drill 1, and a guide shaft groove 61 matching the size of the guide shaft 6 is provided on the barrel 21, so that when the tip 31 of the drill rod 3, the shaft 32 and the spiral conveying part 33 pass through the barrel 21 and the first opening 23 from the second opening 24, the guide shaft 6 is inserted into the guide shaft groove 61.

[0024] In another preferred embodiment, the angle between the cylinder 21 and the discharge barrel 4 is 70° to 80°, so that the extension direction of the discharge barrel 4 is toward the oblique downward direction away from the hay bale, which makes it easier for the storage bag to be fixed on the discharge barrel 4 to further facilitate operation. It also avoids the problem of the hay bale slightly bulging vertically and the discharge barrel 4 colliding with the slightly bulged hay bale, and does not affect the hay sample in the cylinder 21 falling from the discharge barrel 4 into the storage bag.

[0025] This embodiment is only an illustration of the concept and implementation of the present invention, and does not limit it. Under the concept of the present invention, technical solutions that have not been substantially changed are still within the scope of protection.
